Switch to using Go modules. This migrates our vendor.json to use Go 1.11's modules system, and replaces the vendor folder with the output of go mod vendor. The vendored code should remain basically the same; I believe some tree shaking of packages and support scripts/licenses/READMEs/etc. happened. This also fixes Travis and our Makefile to no longer use govendor.

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 [gocomplete](./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](#usage).
|
|
|
|
### Install
|
|
|
|
1. Type in your shell:
|
|
```
|
|
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)
|
