carapace

CircleCI PkgGoDev documentation GoReportCard Coverage Status

Command argument completion generator for cobra. You can read more about it here: A pragmatic approach to shell completion.

Supported shells:

Usage

Calling carapace.Gen on the root command is sufficient to enable completion script generation using the hidden command.

import (
    "github.com/rsteube/carapace"
)

carapace.Gen(rootCmd)

Standalone Mode

Carapace can also be used to provide completion for arbitrary commands as well (similar to aws_completer). See rsteube/carapace-bin for examples. There is also a binary to parse flags from gnu help pages at caraparse.

Example

An example implementation can be found in the [example](./example/) folder.

cd example
go build .

# bash
PATH=$PATH:$(pwd)
source <(example _carapace bash)

# elvish
paths=[[email protected] (pwd)]
eval (example _carapace elvish | slurp)

# fish
set PATH $PATH (pwd) 
example _carapace fish | source

# nushell [needs fork: https://github.com/rsteube/nushell]
example _carapace nushell | save example.nu ; nu -c 'source example.nu'

# oil
PATH=$PATH:$(pwd)
source <(example _carapace oil)

# powershell
Set-PSReadLineOption -Colors @{ "Selection" = "`e[7m" }
Set-PSReadlineKeyHandler -Key Tab -Function MenuComplete
$env:PATH += ":$pwd"
example _carapace powershell | out-string | Invoke-Expression

# tcsh
set autolist
eval `example _carapace tcsh`

# xonsh
$COMPLETION_QUERY_LIMIT = 500 # increase limit
$PATH.append($(pwd))
exec($(example _carapace xonsh))

# zsh
PATH=$PATH:$(pwd)
source <(example _carapace zsh)

example <TAB>

or use docker-compose:

docker-compose pull
docker-compose run --rm build
docker-compose run --rm [bash|elvish|fish|ion|nushell|oil|powershell|tcsh|xonsh|zsh]
