# mousetrap
mousetrap is a tiny library that answers a single question.
On a Windows machine, was the process invoked by someone double clicking on
the executable file while browsing in explorer?
### Motivation
Windows developers unfamiliar with command line tools will often "double-click"
the executable for a tool. Because most CLI tools print the help and then exit
when invoked without arguments, this is often very frustrating for those users.
mousetrap provides a way to detect these invocations so that you can provide
more helpful behavior and instructions on how to run the CLI tool. To see what
this looks like, both from an organizational and a technical perspective, see
https://inconshreveable.com/09-09-2014/sweat-the-small-stuff/
### The interface
The library exposes a single interface:
func StartedByExplorer() (bool)

## Cobra User Contract
### Versioning
Cobra will follow a steady release cadence. Non breaking changes will be released as minor versions quarterly. Patch bug releases are at the discretion of the maintainers. Users can expect security patch fixes to be released within relatively short order of a CVE becoming known. For more information on security patch fixes see the CVE section below. Releases will follow [Semantic Versioning](https://semver.org/). Users tracking the Master branch should expect unpredictable breaking changes as the project continues to move forward. For stability, it is highly recommended to use a release.
### Backward Compatibility
We will maintain two major releases in a moving window. The N-1 release will only receive bug fixes and security updates and will be dropped once N+1 is released.
### Deprecation
Deprecation of Go versions or dependent packages will only occur in major releases. To reduce the change of this taking users by surprise, any large deprecation will be preceded by an announcement in the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) and an Issue on Github.
### CVE
Maintainers will make every effort to release security patches in the case of a medium to high severity CVE directly impacting the library. The speed in which these patches reach a release is up to the discretion of the maintainers. A low severity CVE may be a lower priority than a high severity one.
### Communication
Cobra maintainers will use GitHub issues and the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) as the primary means of communication with the community. This is to foster open communication with all users and contributors.
### Breaking Changes
Breaking changes are generally allowed in the master branch, as this is the branch used to develop the next release of Cobra.
There may be times, however, when master is closed for breaking changes. This is likely to happen as we near the release of a new version.
Breaking changes are not allowed in release branches, as these represent minor versions that have already been released. These version have consumers who expect the APIs, behaviors, etc, to remain stable during the lifetime of the patch stream for the minor release.
Examples of breaking changes include:
- Removing or renaming exported constant, variable, type, or function.
- Updating the version of critical libraries such as `spf13/pflag`, `spf13/viper` etc...
- Some version updates may be acceptable for picking up bug fixes, but maintainers must exercise caution when reviewing.
There may, at times, need to be exceptions where breaking changes are allowed in release branches. These are at the discretion of the project's maintainers, and must be carefully considered before merging.
### CI Testing
Maintainers will ensure the Cobra test suite utilizes the current supported versions of Golang.
### Disclaimer
Changes to this document and the contents therein are at the discretion of the maintainers.
None of the contents of this document are legally binding in any way to the maintainers or the users.

Cobra is a library for creating powerful modern CLI applications.
Cobra is used in many Go projects such as [Kubernetes](https://kubernetes.io/),
[Hugo](https://gohugo.io), and [GitHub CLI](https://github.com/cli/cli) to
name a few. [This list](site/content/projects_using_cobra.md) contains a more extensive list of projects using Cobra.

# Overview
Cobra is a library providing a simple interface to create powerful modern CLI
interfaces similar to git & go tools.
Cobra provides:
* Easy subcommand-based CLIs: `app server`, `app fetch`, etc.
* Fully POSIX-compliant flags (including short & long versions)
* Nested subcommands
* Global, local and cascading flags
* Intelligent suggestions (`app srver`... did you mean `app server`?)
* Automatic help generation for commands and flags
* Grouping help for subcommands
* Automatic help flag recognition of `-h`, `--help`, etc.
* Automatically generated shell autocomplete for your application (bash, zsh, fish, powershell)
* Automatically generated man pages for your application
* Command aliases so you can change things without breaking them
* The flexibility to define your own help, usage, etc.
* Optional seamless integration with [viper](https://github.com/spf13/viper) for 12-factor apps
# Concepts
Cobra is built on a structure of commands, arguments & flags.
**Commands** represent actions, **Args** are things and **Flags** are modifiers for those actions.
The best applications read like sentences when used, and as a result, users
intuitively know how to interact with them.
The pattern to follow is
`APPNAME VERB NOUN --ADJECTIVE`
or
`APPNAME COMMAND ARG --FLAG`.
A few good real world examples may better illustrate this point.
In the following example, 'server' is a command, and 'port' is a flag:
hugo server --port=1313
In this command we are telling Git to clone the url bare.
git clone URL --bare
## Commands
Command is the central point of the application. Each interaction that
the application supports will be contained in a Command. A command can
have children commands and optionally run an action.
In the example above, 'server' is the command.
[More about cobra.Command](https://pkg.go.dev/github.com/spf13/cobra#Command)
## Flags
A flag is a way to modify the behavior of a command. Cobra supports
fully POSIX-compliant flags as well as the Go [flag package](https://golang.org/pkg/flag/).
A Cobra command can define flags that persist through to children commands
and flags that are only available to that command.
In the example above, 'port' is the flag.
Flag functionality is provided by the [pflag
library](https://github.com/spf13/pflag), a fork of the flag standard library
which maintains the same interface while adding POSIX compliance.
# Installing
Using Cobra is easy. First, use `go get` to install the latest version
of the library.
```
go get -u github.com/spf13/cobra@latest
```
Next, include Cobra in your application:
```go
import "github.com/spf13/cobra"
```
# Usage
`cobra-cli` is a command line program to generate cobra applications and command files.
It will bootstrap your application scaffolding to rapidly
develop a Cobra-based application. It is the easiest way to incorporate Cobra into your application.
It can be installed by running:
```
go install github.com/spf13/cobra-cli@latest
```
For complete details on using the Cobra-CLI generator, please read [The Cobra Generator README](https://github.com/spf13/cobra-cli/blob/main/README.md)
For complete details on using the Cobra library, please read the [The Cobra User Guide](site/content/user_guide.md).

[![Go Report Card](https://goreportcard.com/badge/github.com/spf13/pflag)](https://goreportcard.com/report/github.com/spf13/pflag)
[![GoDoc](https://godoc.org/github.com/spf13/pflag?status.svg)](https://godoc.org/github.com/spf13/pflag)
## Description
pflag is a drop-in replacement for Go's flag package, implementing
POSIX/GNU-style --flags.
pflag is compatible with the [GNU extensions to the POSIX recommendations
for command-line options][1]. For a more precise description, see the
"Command-line flag syntax" section below.
[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
pflag is available under the same style of BSD license as the Go language,
which can be found in the LICENSE file.
## Installation
pflag is available using the standard `go get` command.
Install by running:
go get github.com/spf13/pflag
Run tests by running:
go test github.com/spf13/pflag
## Usage
pflag is a drop-in replacement of Go's native flag package. If you import
pflag under the name "flag" then all code should continue to function
with no changes.
``` go
import flag "github.com/spf13/pflag"
```
There is one exception to this: if you directly instantiate the Flag struct
there is one more field "Shorthand" that you will need to set.
Most code never instantiates this struct directly, and instead uses
functions such as String(), BoolVar(), and Var(), and is therefore
unaffected.
Define flags using flag.String(), Bool(), Int(), etc.
This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
``` go
var ip *int = flag.Int("flagname", 1234, "help message for flagname")
```
If you like, you can bind the flag to a variable using the Var() functions.
``` go
var flagvar int
func init() {
flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
}
```
Or you can create custom flags that satisfy the Value interface (with
pointer receivers) and couple them to flag parsing by
``` go
flag.Var(&flagVal, "name", "help message for flagname")
```
For such flags, the default value is just the initial value of the variable.
After all flags are defined, call
``` go
flag.Parse()
```
to parse the command line into the defined flags.
Flags may then be used directly. If you're using the flags themselves,
they are all pointers; if you bind to variables, they're values.
``` go
fmt.Println("ip has value ", *ip)
fmt.Println("flagvar has value ", flagvar)
```
There are helper functions available to get the value stored in a Flag if you have a FlagSet but find
it difficult to keep up with all of the pointers in your code.
If you have a pflag.FlagSet with a flag called 'flagname' of type int you
can use GetInt() to get the int value. But notice that 'flagname' must exist
and it must be an int. GetString("flagname") will fail.
``` go
i, err := flagset.GetInt("flagname")
```
After parsing, the arguments after the flag are available as the
slice flag.Args() or individually as flag.Arg(i).
The arguments are indexed from 0 through flag.NArg()-1.
The pflag package also defines some new functions that are not in flag,
that give one-letter shorthands for flags. You can use these by appending
'P' to the name of any function that defines a flag.
``` go
var ip = flag.IntP("flagname", "f", 1234, "help message")
var flagvar bool
func init() {
flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
}
flag.VarP(&flagVal, "varname", "v", "help message")
```
Shorthand letters can be used with single dashes on the command line.
Boolean shorthand flags can be combined with other shorthand flags.
The default set of command-line flags is controlled by
top-level functions. The FlagSet type allows one to define
independent sets of flags, such as to implement subcommands
in a command-line interface. The methods of FlagSet are
analogous to the top-level functions for the command-line
flag set.
## Setting no option default values for flags
After you create a flag it is possible to set the pflag.NoOptDefVal for
the given flag. Doing this changes the meaning of the flag slightly. If
a flag has a NoOptDefVal and the flag is set on the command line without
an option the flag will be set to the NoOptDefVal. For example given:
``` go
var ip = flag.IntP("flagname", "f", 1234, "help message")
flag.Lookup("flagname").NoOptDefVal = "4321"
```
Would result in something like
| Parsed Arguments | Resulting Value |
| ------------- | ------------- |
| --flagname=1357 | ip=1357 |
| --flagname | ip=4321 |
| [nothing] | ip=1234 |
## Command line flag syntax
```
--flag // boolean flags, or flags with no option default values
--flag x // only on flags without a default value
--flag=x
```
Unlike the flag package, a single dash before an option means something
different than a double dash. Single dashes signify a series of shorthand
letters for flags. All but the last shorthand letter must be boolean flags
or a flag with a default value
```
// boolean or flags where the 'no option default value' is set
-f
-f=true
-abc
but
-b true is INVALID
// non-boolean and flags without a 'no option default value'
-n 1234
-n=1234
-n1234
// mixed
-abcs "hello"
-absd="hello"
-abcs1234
```
Flag parsing stops after the terminator "--". Unlike the flag package,
flags can be interspersed with arguments anywhere on the command line
before this terminator.
Integer flags accept 1234, 0664, 0x1234 and may be negative.
Boolean flags (in their long form) accept 1, 0, t, f, true, false,
TRUE, FALSE, True, False.
Duration flags accept any input valid for time.ParseDuration.
## Mutating or "Normalizing" Flag names
It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow.
**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag
``` go
func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
from := []string{"-", "_"}
to := "."
for _, sep := range from {
name = strings.Replace(name, sep, to, -1)
}
return pflag.NormalizedName(name)
}
myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc)
```
**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name
``` go
func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
switch name {
case "old-flag-name":
name = "new-flag-name"
break
}
return pflag.NormalizedName(name)
}
myFlagSet.SetNormalizeFunc(aliasNormalizeFunc)
```
## Deprecating a flag or its shorthand
It is possible to deprecate a flag, or just its shorthand. Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used.
**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead.
```go
// deprecate a flag by specifying its name and a usage message
flags.MarkDeprecated("badflag", "please use --good-flag instead")
```
This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used.
**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n".
```go
// deprecate a flag shorthand by specifying its flag name and a usage message
flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only")
```
This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used.
Note that usage message is essential here, and it should not be empty.
## Hidden flags
It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
```go
// hide a flag by specifying its name
flags.MarkHidden("secretFlag")
```
## Disable sorting of flags
`pflag` allows you to disable sorting of flags for help and usage message.
**Example**:
```go
flags.BoolP("verbose", "v", false, "verbose output")
flags.String("coolflag", "yeaah", "it's really cool flag")
flags.Int("usefulflag", 777, "sometimes it's very useful")
flags.SortFlags = false
flags.PrintDefaults()
```
**Output**:
```
-v, --verbose verbose output
--coolflag string it's really cool flag (default "yeaah")
--usefulflag int sometimes it's very useful (default 777)
```
## Supporting Go flags when using pflag
In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
to support flags defined by third-party dependencies (e.g. `golang/glog`).
**Example**: You want to add the Go flags to the `CommandLine` flagset
```go
import (
goflag "flag"
flag "github.com/spf13/pflag"
)
var ip *int = flag.Int("flagname", 1234, "help message for flagname")
func main() {
flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
flag.Parse()
}
```
## More info
You can see the full reference documentation of the pflag package
[at godoc.org][3], or through go's standard documentation system by
running `godoc -http=:6060` and browsing to
[http://localhost:6060/pkg/github.com/spf13/pflag][2] after
