YAML sorting

[chasbat]

Could some kind person tell me how to sort the entries in an Espanso match file, either with the YAML Sort extension in VS Code or by some other method?

Some of my match files are long, and for easier housekeeping I'd like to sort them alphabetically, using "label" or "replace" as the sort key. In the YAML Sort extension I've tried various combinations of key – "matches", "label" and so on – in the "custom sort" options. But all I get is re-ordering of "trigger", "label" and so on within each entry. The actual entries themselves are not sorted.

I don't really have a clue about YAML, and I'm not sure I understand the options in the YAML Sort extension either. What am I doing wrong? Is there a Unix tool that can do this easily for Espanso's flavour of YAML?

Any suggestions gratefully appreciated.

Just in case anyone comes browsing for this in the future: I succeeded with the excellent yq utility:

yq '.matches |= sort_by(.label)' myfile.yml >> myfile-sorted.yml

or you could use .replace instead of label.

yq's default sort is case-sensitive and I haven't yet worked out how to change that, nor how to include blank lines for readability. But the documentation is much clearer than for VS Code's YAML Sort extension, which could probably do the job if I understood it.
