Hi, I am using the function below which is adapted from http://lilypondblog.org/2014/01/why-use-version-control-for-engraving-scores/#more-2151
While it works and the .ly files compile successfully, the function issues a warning (?) I’d like to get rid of. 1) If the document is in a git directory, this is printed: Parsing...git: /…path/to…/lilypond-2.20.0-1/lilypond/usr/lib/libz.so.1: no version information available (required by git) Where does it come from and why is it issued? Doing `git --version` in bash does not issue it. 2) If the document is not in a git repository another log line is added: fatal: not a git repository (or any of the parent directories): .git Which I understand but I’d like to hide it anyways because I want to use the same file no matter if it is used with git or not. Any ideas how to achieve this? Cheers, Joram %%%% code \version "2.20.0" #(use-modules (ice-9 popen)) #(use-modules (ice-9 rdelim)) #(define (strsystem_internal cmd) (let* ((port (open-input-pipe cmd)) (str (read-line port))) (close-pipe port) str)) #(define gitshort (let* ((res (strsystem_internal "git describe --long --dirty='+' | sed 's/-/./' | sed -r 's/-g[0-9a-f]+//g'"))) (if (string? res) res ""))) % if (string? ... is my clumsy way to ensure it returns a string \markup { "Version" \gitshort }
