## This file is designed to be sourced from a bash script whose name takes the
## form 'command-name'. This script will then instead invoke
## '[depot_tools]/command_name.py' correctly under mingw as well
## as posix-ey systems, passing along all other command line flags.
## Example:
## echo ". python_runner.sh" > git-foo-command
## ./git-foo-command #=> runs `python git_foo_command.py`

# SCRIPT defaults to the basename of $0, with dashes replaced with underscores
# "$0" can have several different formats depending on how the script was called
# and the environment being used, including having different formats even in the
# same environment (e.g. in msys, 'git cl' causes $0 to have a Windows-style
# path, but calling 'git-cl' results in a POSIX-style path), so don't assume a
# particular format.
# First try to split it using Windows format ...
DEPOT_TOOLS="${0%\\*}"
if [[ "$DEPOT_TOOLS" = "$0" ]]; then
# If that didn't work, try POSIX format ...
DEPOT_TOOLS="${0%/*}"
if [[ "$DEPOT_TOOLS" = "$0" ]]; then
# Sometimes commands will run with no path (e.g. a git command run from
# within the depot_tools dir itself). In that case, treat it as if run like:
# "./command"
