| # This script wraps a binary that does not generate any output file, but |
| # can return a status (success or fail). Ninja actions need an output to |
| # resolve dependencies, so this wrapper creates or updates a stamp file |
| # with the date/time of the last success. |
| |
| # Stamp file to touch after the command runs successfully |
| stamp="$1" |
| shift |
| |
| # Execute the command and check return status |
| "$@" |
| status=$? |
| # only update the stamp file if the command returned a successful status |
| if (( $status == 0 )); then |
| touch "${stamp}" |
