`depth` is tool to retrieve and visualize Go source code dependency trees.
## Install
Download the appropriate binary for your platform from the [Releases](https://github.com/KyleBanks/depth/releases) page, or:
```sh
go get github.com/KyleBanks/depth/cmd/depth
```
## Usage
`depth` can be used as a standalone command-line application, or as a package within your own project.
### Command-Line
Simply execute `depth` with one or more package names to visualize. You can use the fully qualified import path of the package, like so:
```sh
$ depth github.com/KyleBanks/depth/cmd/depth
github.com/KyleBanks/depth/cmd/depth
├ encoding/json
├ flag
├ fmt
├ io
├ log
├ os
├ strings
└ github.com/KyleBanks/depth
├ fmt
├ go/build
├ path
├ sort
└ strings
12 dependencies (11 internal, 1 external, 0 testing).
```
Or you can use a relative path, for example:
```sh
$ depth .
$ depth ./cmd/depth
$ depth ../
```
You can also use `depth` on the Go standard library:
```sh
$ depth strings
strings
├ errors
├ io
├ unicode
└ unicode/utf8
5 dependencies (5 internal, 0 external, 0 testing).
```
Visualizing multiple packages at a time is supported by simply naming the packages you'd like to visualize:
```sh
$ depth strings github.com/KyleBanks/depth
strings
├ errors
├ io
├ unicode
└ unicode/utf8
5 dependencies (5 internal, 0 external, 0 testing).
github.com/KyleBanks/depth
├ fmt
├ go/build
├ path
├ sort
└ strings
7 dependencies (7 internal, 0 external, 0 testing).
```
#### `-internal`
By default, `depth` only resolves the top level of dependencies for standard library packages, however you can use the `-internal` flag to visualize all internal dependencies:
```sh
$ depth -internal strings
strings
├ errors
├ io
├ errors
└ sync
├ internal/race
└ unsafe
├ runtime
├ runtime/internal/atomic
└ unsafe
├ runtime/internal/sys
└ unsafe
├ sync/atomic
└ unsafe
└ unsafe
├ unicode
└ unicode/utf8
12 dependencies (12 internal, 0 external, 0 testing).
```
#### `-max`
The `-max` flag limits the dependency tree to the maximum depth provided. For example, if you supply `-max 1` on the `depth` package, your output would look like so:
```
$ depth -max 1 github.com/KyleBanks/depth/cmd/depth
github.com/KyleBanks/depth/cmd/depth
├ encoding/json
├ flag
├ fmt
├ io
├ log
├ os
├ strings
└ github.com/KyleBanks/depth
7 dependencies (6 internal, 1 external, 0 testing).
```
The `-max` flag is particularly useful in conjunction with the `-internal` flag which can lead to very deep dependency trees.
#### `-test`
By default, `depth` ignores dependencies that are only required for testing. However, you can view test dependencies using the `-test` flag:
```sh
$ depth -test strings
strings
├ bytes
├ errors
├ fmt
├ io
├ io/ioutil
├ math/rand
├ reflect
├ sync
├ testing
├ unicode
├ unicode/utf8
└ unsafe
13 dependencies (13 internal, 0 external, 8 testing).
```
#### `-explain target-package`
The `-explain` flag instructs `depth` to print import chains in which the
`target-package` is found:
```sh
$ depth -explain strings github.com/KyleBanks/depth/cmd/depth
github.com/KyleBanks/depth/cmd/depth -> strings
github.com/KyleBanks/depth/cmd/depth -> github.com/KyleBanks/depth -> strings
```
#### `-json`
The `-json` flag instructs `depth` to output dependencies in JSON format:
```sh
$ depth -json github.com/KyleBanks/depth/cmd/depth
{
"name": "github.com/KyleBanks/depth/cmd/depth",
"deps": [
{
"name": "encoding/json",
"internal": true,
"deps": null
},
...
{
"name": "github.com/KyleBanks/depth",
"internal": false,
"deps": [
{
"name": "go/build",
"internal": true,
"deps": null
},
...
]
}
]
}
```
### Integrating With Your Project
The `depth` package can easily be used to retrieve the dependency tree for a particular package in your own project. For example, here's how you would retrieve the dependency tree for the `strings` package:
```go
import "github.com/KyleBanks/depth"
var t depth.Tree
err := t.Resolve("strings")
if err != nil {
log.Fatal(err)
}
// Output: "'strings' has 4 dependencies."
log.Printf("'%v' has %v dependencies.", t.Root.Name, len(t.Root.Deps))
```
For additional customization, simply set the appropriate flags on the `Tree` before resolving:
```go
import "github.com/KyleBanks/depth"
t := depth.Tree {
ResolveInternal: true,
ResolveTest: true,
MaxDepth: 10,
}
err := t.Resolve("strings")
```

# Changelog
1.9.0 2024-04-04
----------------
### Changes and fixes
- all: make BufferedWatcher buffered again ([#657])

1.7.0 - 2023-10-22
------------------
This version of fsnotify needs Go 1.17.
### Additions
- illumos: add FEN backend to support illumos and Solaris. ([#371])
- all: add `NewBufferedWatcher()` to use a buffered channel, which can be useful
in cases where you can't control the kernel buffer and receive a large number
of events in bursts. ([#550], [#572])
- all: add `AddWith()`, which is identical to `Add()` but allows passing
options. ([#521])
- windows: allow setting the ReadDirectoryChangesW() buffer size with
`fsnotify.WithBufferSize()`; the default of 64K is the highest value that
works on all platforms and is enough for most purposes, but in some cases a
highest buffer is needed. ([#521])
### Changes and fixes
- inotify: remove watcher if a watched path is renamed ([#518])
After a rename the reported name wasn't updated, or even an empty string.
Inotify doesn't provide any good facilities to update it, so just remove the
watcher. This is already how it worked on kqueue and FEN.
On Windows this does work, and remains working.
- windows: don't listen for file attribute changes ([#520])
File attribute changes are sent as `FILE_ACTION_MODIFIED` by the Windows API,
with no way to see if they're a file write or attribute change, so would show
up as a fsnotify.Write event. This is never useful, and could result in many
spurious Write events.
- windows: return `ErrEventOverflow` if the buffer is full ([#525])
Before it would merely return "short read", making it hard to detect this
error.
- kqueue: make sure events for all files are delivered properly when removing a
watched directory ([#526])
Previously they would get sent with `""` (empty string) or `"."` as the path
name.
- kqueue: don't emit spurious Create events for symbolic links ([#524])
The link would get resolved but kqueue would "forget" it already saw the link
itself, resulting on a Create for every Write event for the directory.
- all: return `ErrClosed` on `Add()` when the watcher is closed ([#516])
- other: add `Watcher.Errors` and `Watcher.Events` to the no-op `Watcher` in
`backend_other.go`, making it easier to use on unsupported platforms such as
WASM, AIX, etc. ([#528])
- other: use the `backend_other.go` no-op if the `appengine` build tag is set;
Google AppEngine forbids usage of the unsafe package so the inotify backend
won't compile there.

1.6.0 - 2022-10-13
------------------
This version of fsnotify needs Go 1.16 (this was already the case since 1.5.1,
but not documented). It also increases the minimum Linux version to 2.6.32.
### Additions
- all: add `Event.Has()` and `Op.Has()` ([#477])
This makes checking events a lot easier; for example:
if event.Op&Write == Write && !(event.Op&Remove == Remove) {
}
Becomes:
if event.Has(Write) && !event.Has(Remove) {
}
- all: add cmd/fsnotify ([#463])
A command-line utility for testing and some examples.
### Changes and fixes
- inotify: don't ignore events for files that don't exist ([#260], [#470])
Previously the inotify watcher would call `os.Lstat()` to check if a file
still exists before emitting events.
This was inconsistent with other platforms and resulted in inconsistent event
reporting (e.g. when a file is quickly removed and re-created), and generally
a source of confusion. It was added in 2013 to fix a memory leak that no
longer exists.
- all: return `ErrNonExistentWatch` when `Remove()` is called on a path that's
not watched ([#460])
- inotify: replace epoll() with non-blocking inotify ([#434])
Non-blocking inotify was not generally available at the time this library was
written in 2014, but now it is. As a result, the minimum Linux version is
bumped from 2.6.27 to 2.6.32. This hugely simplifies the code and is faster.
- kqueue: don't check for events every 100ms ([#480])
The watcher would wake up every 100ms, even when there was nothing to do. Now
it waits until there is something to do.
- macos: retry opening files on EINTR ([#475])
- kqueue: skip unreadable files ([#479])
kqueue requires a file descriptor for every file in a directory; this would
fail if a file was unreadable by the current user. Now these files are simply
skipped.
- windows: fix renaming a watched directory if the parent is also watched ([#370])
- windows: increase buffer size from 4K to 64K ([#485])
- windows: close file handle on Remove() ([#288])
- kqueue: put pathname in the error if watching a file fails ([#471])
- inotify, windows: calling Close() more than once could race ([#465])
- kqueue: improve Close() performance ([#233])
- all: various documentation additions and clarifications.

Thank you for your interest in contributing to fsnotify! We try to review and
merge PRs in a reasonable timeframe, but please be aware that:
- To avoid "wasted" work, please discuss changes on the issue tracker first. You
can just send PRs, but they may end up being rejected for one reason or the
other.
- fsnotify is a cross-platform library, and changes must work reasonably well on
all supported platforms.
- Changes will need to be compatible; old code should still compile, and the
runtime behaviour can't change in ways that are likely to lead to problems for
users.
Testing
-------
Just `go test ./...` runs all the tests; the CI runs this on all supported
platforms. Testing different platforms locally can be done with something like
[goon] or [Vagrant], but this isn't super-easy to set up at the moment.
Use the `-short` flag to make the "stress test" run faster.
Writing new tests
-----------------
Scripts in the testdata directory allow creating test cases in a "shell-like"
syntax. The basic format is:
script
Output:
desired output
For example:
# Create a new empty file with some data.
watch /
echo data >/file
Output:
create /file
write /file
Just create a new file to add a new test; select which tests to run with
`-run TestScript/[path]`.
script
------
The script is a "shell-like" script:
cmd arg arg
Comments are supported with `#`:
# Comment
cmd arg arg # Comment
All operations are done in a temp directory; a path like "/foo" is rewritten to
"/tmp/TestFoo/foo".
Arguments can be quoted with `"` or `'`; there are no escapes and they're
functionally identical right now, but this may change in the future, so best to
assume shell-like rules.
touch "/file with spaces"
End-of-line escapes with `\` are not supported.
### Supported commands
watch path [ops] # Watch the path, reporting events for it. Nothing is
# watched by default. Optionally a list of ops can be
# given, as with AddWith(path, WithOps(...)).
unwatch path # Stop watching the path.
watchlist n # Assert watchlist length.
stop # Stop running the script; for debugging.
debug [yes/no] # Enable/disable FSNOTIFY_DEBUG (tests are run in
parallel by default, so -parallel=1 is probably a good
idea).
print [any strings] # Print text to stdout; for debugging.
touch path
mkdir [-p] dir
ln -s target link # Only ln -s supported.
mkfifo path
mknod dev path
mv src dst
rm [-r] path
chmod mode path # Octal only
sleep time-in-ms
cat path # Read path (does nothing with the data; just reads it).
echo str >>path # Append "str" to "path".
echo str >path # Truncate "path" and write "str".
require reason # Skip the test if "reason" is true; "skip" and
skip reason # "require" behave identical; it supports both for
# readability. Possible reasons are:
#
# always Always skip this test.
# symlink Symlinks are supported (requires admin
# permissions on Windows).
# mkfifo Platform doesn't support FIFO named sockets.
# mknod Platform doesn't support device nodes.
output
------
After `Output:` the desired output is given; this is indented by convention, but
that's not required.
The format of that is:
# Comment
event path # Comment
system:
event path
system2:
event path
Every event is one line, and any whitespace between the event and path are
ignored. The path can optionally be surrounded in ". Anything after a "#" is
ignored.
Platform-specific tests can be added after GOOS; for example:
watch /
touch /file
Output:
# Tested if nothing else matches
create /file
# Windows-specific test.
windows:
write /file
You can specify multiple platforms with a comma (e.g. "windows, linux:").
"kqueue" is a shortcut for all kqueue systems (BSD, macOS).

Usage
-----
A basic example:
```go
package main
import (
"log"
"github.com/fsnotify/fsnotify"
)
func main() {
// Create new watcher.
watcher, err := fsnotify.NewWatcher()
if err != nil {
log.Fatal(err)
}
defer watcher.Close()
// Start listening for events.
go func() {
for {
select {
case event, ok := <-watcher.Events:
if !ok {
return
}
log.Println("event:", event)
if event.Has(fsnotify.Write) {
log.Println("modified file:", event.Name)
}
case err, ok := <-watcher.Errors:
if !ok {
return
}
log.Println("error:", err)
}
}
}()
// Add a path.
err = watcher.Add("/tmp")
if err != nil {
log.Fatal(err)
}
// Block main goroutine forever.
<-make(chan struct{})
}
```
Some more examples can be found in [cmd/fsnotify](cmd/fsnotify), which can be
run with:
% go run ./cmd/fsnotify

FAQ
---
### Will a file still be watched when it's moved to another directory?
No, not unless you are watching the location it was moved to.
### Are subdirectories watched?
No, you must add watches for any directory you want to watch (a recursive
watcher is on the roadmap: [#18]).
[#18]: https://github.com/fsnotify/fsnotify/issues/18
### Do I have to watch the Error and Event channels in a goroutine?
Yes. You can read both channels in the same goroutine using `select` (you don't
need a separate goroutine for both channels; see the example).
### Why don't notifications work with NFS, SMB, FUSE, /proc, or /sys?
fsnotify requires support from underlying OS to work. The current NFS and SMB
protocols does not provide network level support for file notifications, and
neither do the /proc and /sys virtual filesystems.
This could be fixed with a polling watcher ([#9]), but it's not yet implemented.
[#9]: https://github.com/fsnotify/fsnotify/issues/9
### Why do I get many Chmod events?
Some programs may generate a lot of attribute changes; for example Spotlight on
macOS, anti-virus programs, backup applications, and some others are known to do
this. As a rule, it's typically best to ignore Chmod events. They're often not
useful, and tend to cause problems.
Spotlight indexing on macOS can result in multiple events (see [#15]). A
temporary workaround is to add your folder(s) to the *Spotlight Privacy
settings* until we have a native FSEvents implementation (see [#11]).
[#11]: https://github.com/fsnotify/fsnotify/issues/11
[#15]: https://github.com/fsnotify/fsnotify/issues/15
### Watching a file doesn't work well
Watching individual files (rather than directories) is generally not recommended
as many programs (especially editors) update files atomically: it will write to
a temporary file which is then moved to to destination, overwriting the original
(or some variant thereof). The watcher on the original file is now lost, as that
no longer exists.
The upshot of this is that a power failure or crash won't leave a half-written
file.
Watch the parent directory and use `Event.Name` to filter out files you're not
interested in. There is an example of this in `cmd/fsnotify/file.go`.
Platform-specific notes
-----------------------
### Linux
When a file is removed a REMOVE event won't be emitted until all file
descriptors are closed; it will emit a CHMOD instead:
fp := os.Open("file")
os.Remove("file") // CHMOD
fp.Close() // REMOVE
This is the event that inotify sends, so not much can be changed about this.
The `fs.inotify.max_user_watches` sysctl variable specifies the upper limit for
the number of watches per user, and `fs.inotify.max_user_instances` specifies
the maximum number of inotify instances per user. Every Watcher you create is an
"instance", and every path you add is a "watch".
These are also exposed in `/proc` as `/proc/sys/fs/inotify/max_user_watches` and
`/proc/sys/fs/inotify/max_user_instances`
To increase them you can use `sysctl` or write the value to proc file:
# The default values on Linux 5.18
sysctl fs.inotify.max_user_watches=124983
sysctl fs.inotify.max_user_instances=128
To make the changes persist on reboot edit `/etc/sysctl.conf` or
`/usr/lib/sysctl.d/50-default.conf` (details differ per Linux distro; check your
distro's documentation):
fs.inotify.max_user_watches=124983
fs.inotify.max_user_instances=128
Reaching the limit will result in a "no space left on device" or "too many open
files" error.
### kqueue (macOS, all BSD systems)
kqueue requires opening a file descriptor for every file that's being watched;
so if you're watching a directory with five files then that's six file
descriptors. You will run in to your system's "max open files" limit faster on
these platforms.
The sysctl variables `kern.maxfiles` and `kern.maxfilesperproc` can be used to
control the maximum number of open files.

// - illumos via FEN
//
// # FSNOTIFY_DEBUG
//
// Set the FSNOTIFY_DEBUG environment variable to "1" to print debug messages to

// your distro's documentation):
//
// fs.inotify.max_user_watches=124983

// # kqueue notes (macOS, BSD)
//
// kqueue requires opening a file descriptor for every file that's being watched;
// so if you're watching a directory with five files then that's six file
// descriptors. You will run in to your system's "max open files" limit faster on
// these platforms.
//
// The sysctl variables kern.maxfiles and kern.maxfilesperproc can be used to
// control the maximum number of open files, as well as /etc/login.conf on BSD
// systems.
//
// # Windows notes
//
// Paths can be added as "C:\\path\\to\\dir", but forward slashes
// ("C:/path/to/dir") will also work.
//
// When a watched directory is removed it will always send an event for the
// directory itself, but may not send events for all files in that directory.
// Sometimes it will send events for all files, sometimes it will send no
// events, and often only for some files.
//
// The default ReadDirectoryChangesW() buffer size is 64K, which is the largest
// value that is guaranteed to work with SMB filesystems. If you have many
// events in quick succession this may not be enough, and you will have to use
// [WithBufferSize] to increase the value.

// fsnotify can send the following events; a "path" here can refer to a

//
// fsnotify.Create A new path was created; this may be followed by one
// or more Write events if data also gets written to a
// file.
//
// fsnotify.Remove A path was removed.
//
// fsnotify.Rename A path was renamed. A rename is always sent with the
// old path as Event.Name, and a Create event will be
// sent with the new name. Renames are only sent for
// paths that are currently watched; e.g. moving an
// unmonitored file into a monitored directory will
// show up as just a Create. Similarly, renaming a file
// to outside a monitored directory will show up as
// only a Rename.
//
// fsnotify.Write A file or named pipe was written to. A Truncate will
// also trigger a Write. A single "write action"
// initiated by the user may show up as one or multiple
// writes, depending on when the system syncs things to
// disk. For example when compiling a large Go program
// you may get hundreds of Write events, and you may
// want to wait until you've stopped receiving them
// (see the dedup example in cmd/fsnotify).
//
// Some systems may send Write event for directories
// when the directory content changes.
//
// fsnotify.Chmod Attributes were changed. On Linux this is also sent
// when a file is removed (or more accurately, when a
// link to an inode is removed). On kqueue it's sent
// when a file is truncated. On Windows it's never
// sent.

//

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]

where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.

wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,

(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

The object model for OpenAPI specification documents.
### FAQ
* What does this do?
> 1. This package knows how to marshal and unmarshal Swagger API specifications into a golang object model
> 2. It knows how to resolve $ref and expand them to make a single root document
* How does it play with the rest of the go-openapi packages ?
> 1. This package is at the core of the go-openapi suite of packages and [code generator](https://github.com/go-swagger/go-swagger)
> 2. There is a [spec loading package](https://github.com/go-openapi/loads) to fetch specs as JSON or YAML from local or remote locations
> 3. There is a [spec validation package](https://github.com/go-openapi/validate) built on top of it
> 4. There is a [spec analysis package](https://github.com/go-openapi/analysis) built on top of it, to analyze, flatten, fix and merge spec documents
* Does this library support OpenAPI 3?
> No.
> This package currently only supports OpenAPI 2.0 (aka Swagger 2.0).
> There is no plan to make it evolve toward supporting OpenAPI 3.x.
> This [discussion thread](https://github.com/go-openapi/spec/issues/21) relates the full story.
>
> An early attempt to support Swagger 3 may be found at: https://github.com/go-openapi/spec3

// Parameter a unique parameter is defined by a combination of a [name](#parameterName) and [location](#parameterIn).
//
// There are five possible parameter types.
// * Path - Used together with [Path Templating](#pathTemplating), where the parameter value is actually part
// of the operation's URL. This does not include the host or base path of the API. For example, in `/items/{itemId}`,
// the path parameter is `itemId`.
// * Query - Parameters that are appended to the URL. For example, in `/items?id=###`, the query parameter is `id`.
// * Header - Custom headers that are expected as part of the request.
// * Body - The payload that's appended to the HTTP request. Since there can only be one payload, there can only be
// _one_ body parameter. The name of the body parameter has no effect on the parameter itself and is used for
// documentation purposes only. Since Form parameters are also in the payload, body and form parameters cannot exist
// together for the same operation.
// * Form - Used to describe the payload of an HTTP request when either `application/x-www-form-urlencoded` or
// `multipart/form-data` are used as the content type of the request (in Swagger's definition,
// the [`consumes`](#operationConsumes) property of an operation). This is the only parameter type that can be used
// to send files, thus supporting the `file` type. Since form parameters are sent in the payload, they cannot be
// declared together with a body parameter for the same operation. Form parameters have a different format based on
// the content-type used (for further details, consult http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4).
// * `application/x-www-form-urlencoded` - Similar to the format of Query parameters but as a payload.
// For example, `foo=1&bar=swagger` - both `foo` and `bar` are form parameters. This is normally used for simple
// parameters that are being transferred.
// * `multipart/form-data` - each parameter takes a section in the payload with an internal header.
// For example, for the header `Content-Disposition: form-data; name="submit-name"` the name of the parameter is
// `submit-name`. This type of form parameters is more commonly used for file transfers.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.

3. Grant of Patent License. Subject to the terms and conditions of

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.
