Generate tab completion for any shell command by specifying its usage in a
familiar manpage-like format. For example, a usage specification for
top(1):
top [-b | -c | -H | -i | -s | -S | -d <delay> | -n <num> | -p <pid> ...] ... ;
top (-h|-v)
Supported shells are bash, fish, and zsh.
Get the source code: git clone git://github.com/mbrubeck/compleat.git
Next, install Stack.
To install Compleat in your system, run:
make install
This will install the compleat binary into ~/.local/bin and the
compleat_setup script into $BASH_COMPLETION_USER_DIR (defaults to
$XDG_DATA_HOME/bash-completion/completions or
~/.local/share/bash-completion/completions):
To enable compleat in bash, add the following line to your .bashrc.
(Adjust the path if you configured with a custom prefix.)
source ${BASH_COMPLETION_USER_DIR}/compleat_setup
and install your .usage files in a directory named /etc/compleat.d or
~/.compleat:
mkdir ~/compleat
cp examples/* ~/compleat
Restart your shell to begin using completions:
exec bash
zsh support requires zsh >= 4.2.1, and currently uses zsh's bash-compatibility mode rather than taking advantage of zsh's extended completion features.
To enable compleat in zsh, make the following change to your .zshrc.
(Adjust the path if you configured with a custom prefix.)
If you used the zsh wizard (zsh-newuser-install) to set up your zshrc, it should contain lines
like the following (if they don't exist, simply add the lines in the change below):
autoload -Uz compinit
compinit
Change these to:
autoload -Uz compinit bashcompinit
compinit
bashcompinit
source ~/.bash_completion.d/compleat_setup
and install your .usage files in a directory named /etc/compleat.d or
~/.compleat:
sudo mkdir /etc/compleat.d
sudo cp examples/* /etc/compleat.d
Restart your shell to begin using completions:
exec zsh
To install the fish completion file, run:
make install-fish
To enable compleat in fish, add the following line to your ~/.config/fish/config.fish.
source ~/.config/fish/compleat_setup.fish
and install your .usage files in a directory named /etc/compleat.d or
~/.compleat:
mkdir ~/compleat
cp examples/* ~/compleat
Restart your shell to begin using completions:
exec fish
Type top and then press Tab a few times to see the example files in action.
A usage file contains commands and definitions, separated by semicolons.
A command consists of a command name followed by a pattern. The command name can be any atom. If there is more than one command in the file, compleat will attempt to match each of them against the input line.
An atom consists of letters, numbers, and any of the characters -_/@=+.,:,
or any string enclosed in double quotes with C/Java-style backslash escapes.
The following are valid patterns:
- Any atom matches itself:
foomatches the stringfoo."x\\y"matches the stringx\y. a bmatchesafollowed byb.a b | cmatches eithera borc.[a]matches zero or one occurrences ofa.a ...matches one or more occurrences ofa.[a] ...matches zero or more occurrences ofa.
Use parentheses to group patterns:
a (b | c)matchesafollowed by eitherborc.(a | b) ...matchesaorbfollowed by any number of additionalaorb.
Patterns may also include variables:
-
name = value;defines a new variable. The name can be any atom, and the value can be any pattern. Then<name>in a pattern refers to the value as a sub-pattern. -
name = !command;defines a variable that uses a shell command to generate suggested completions. The shell command should print one suggested completion per line. The$COMP_LINEand$COMP_CWORDenvironment will contain the input line and the current word being completed. -
If no value is defined for
name, then the pattern<name>will match any word.
