# Each path is installed into the appropriate directory for shell completions for the given shell.
|
||||
# If one of `--bash`, `--fish`, or `--zsh` is given the path is assumed to belong to that shell.
|
||||
# Otherwise the file extension will be examined to pick a shell. If the shell is unknown a warning
|
||||
# will be logged and the command will return a non-zero status code after processing any remaining
|
||||
# paths. Any of the shell flags will affect all subsequent paths (unless another shell flag is
|
||||
# given).
|
||||
#
|
||||
# If the shell completion needs to be renamed before installing the optional `--name <name>` flag
|
||||
# may be given. Any name provided with this flag only applies to the next path.
|
||||
#
|
||||
# For zsh completions, if the `--name` flag is not given, the path will be automatically renamed
|
||||
# such that `foobar.zsh` becomes `_foobar`.
|
||||
#
|
||||
# This command accepts multiple shell flags in conjunction with multiple paths if you wish to
|
||||
# install them all in one command:
|

#
|

# installShellCompletion share/completions/foobar.{bash,fish} --zsh share/completions/_foobar
|

||||
# However it may be easier to read if each shell is split into its own invocation, especially when
|
||||
# renaming is involved:
|
||||
#
|
||||
# installShellCompletion --bash --name foobar.bash share/completions.bash
|

# installShellCompletion --fish --name foobar.fish share/completions.fish
