Package complete provides a tool for bash writing bash completion in go, and bash completion for the go command line.
Writing bash completion scripts is a hard work. This package provides an easy way
to create bash completion scripts for any command, and also an easy way to install/uninstall
the completion of the command.
#### Go Command Bash Completion
In [./cmd/gocomplete](./cmd/gocomplete) there is an example for bash completion for the `go` command line.
This is an example that uses the `complete` package on the `go` command - the `complete` package
can also be used to implement any completions, see #usage.
#### Install
1. Type in your shell:
```go
go get -u github.com/posener/complete/gocomplete
gocomplete -install
```
2. Restart your shell
Uninstall by `gocomplete -uninstall`
#### Features
- Complete `go` command, including sub commands and all flags.
- Complete packages names or `.go` files when necessary.
- Complete test names after `-run` flag.
#### Complete package
Supported shells:
- [x] bash
- [x] zsh
- [x] fish
#### Usage
Assuming you have program called `run` and you want to have bash completion
for it, meaning, if you type `run` then space, then press the `Tab` key,
the shell will suggest relevant complete options.
In that case, we will create a program called `runcomplete`, a go program,
with a `func main()` and so, that will make the completion of the `run`
program. Once the `runcomplete` will be in a binary form, we could
`runcomplete -install` and that will add to our shell all the bash completion
options for `run`.
So here it is:
```go
import "github.com/posener/complete"
func main() {
// create a Command object, that represents the command we want
// to complete.
run := complete.Command{
// Sub defines a list of sub commands of the program,
// this is recursive, since every command is of type command also.
Sub: complete.Commands{
// add a build sub command
"build": complete.Command {
// define flags of the build sub command
Flags: complete.Flags{
// build sub command has a flag '-cpus', which
// expects number of cpus after it. in that case
// anything could complete this flag.
"-cpus": complete.PredictAnything,
},
},
},
// define flags of the 'run' main command
Flags: complete.Flags{
// a flag -o, which expects a file ending with .out after
// it, the tab completion will auto complete for files matching
// the given pattern.
"-o": complete.PredictFiles("*.out"),
},
// define global flags of the 'run' main command
// those will show up also when a sub command was entered in the
// command line
GlobalFlags: complete.Flags{
// a flag '-h' which does not expects anything after it
"-h": complete.PredictNothing,
},
}
// run the command completion, as part of the main() function.
// this triggers the autocompletion when needed.
// name must be exactly as the binary that we want to complete.
complete.New("run", run).Run()
}
```
#### Self completing program
In case that the program that we want to complete is written in go we
can make it self completing.
Here is an example: [./example/self/main.go](./example/self/main.go) .
## Sub Packages
* [cmd](./cmd): Package cmd used for command line options for the complete tool
* [gocomplete](./gocomplete): Package main is complete tool for the go command line
* [match](./match): Package match contains matchers that decide if to apply completion.
