Lefthook Documentation

use_stdin

Note: With many commands or scripts having use_stdin: true, only one will receive the data. The others will have nothing. If you need to pass the data from stdin to every command or script, please, submit a feature request.

Pass the stdin from the OS to the command/script.

Example

Use this option for the pre-push hook when you have a script that does while read .... Without this option lefthook will hang: lefthook uses pseudo TTY by default, and it doesn't close stdin when all data is read.

# .lefthook/pre-push/do-the-magic.sh

remote="$1"
url="$2"

while read local_ref local_oid remote_ref remote_oid; do
  # ...
done

# lefthook.yml
pre-push:
  scripts:
    "do-the-magic.sh":
      runner: bash
      use_stdin: true
