This is similar in spirit to the helper flags in git subcommands, e.g. try `git branch --git-completion-helper`. It provides a list of long flags that the subcommands support, without repeating it manually in the completion script. Note that this special flag is not returned in help, so there is no noise. To see the result, source the script, then `git cl upload --<TAB>`.

# This adds completion to bash shells for git cl commands. It is
|
|
# meant for developers and not needed for inclusion by any automated
|
|
# processes that will, of course, specify the full command, not rely
|
|
# on or benefit from tab-completion.
|
|
#
|
|
# Requires:
|
|
# Installed git bash completion.
|
|
#
|
|
# Usage:
|
|
# Put something like the following in your .bashrc:
|
|
# . $PATH_TO_DEPOT_TOOLS/git cl_completion.sh
|
|
#
|
|
|
|
|
|
# Parses commands from git cl -h.
