Regarding the templating of weechat conf files:
I think this is a great example of how to combine:
- tt-render command: https://github.com/ingydotnet/weechat-dots/blob/master/Makefile#L7
- YAML data: https://github.com/ingydotnet/weechat-dots/blob/master/weechat.yaml
- tt2 templates: https://github.com/ingydotnet/weechat-dots/blob/master/template/weechat.conf#L237
I coded up the YAML real tasty (DRY), and then wrote code in tt2 to slice it up various ways, thus avoiding any auxiliary Perl helper script. All in all, pretty elegant.
In this case (weechat), I'm not sure it plays out because it works against the save_layout_on_exit workflow, if you prefer to work that way. Time will tell.
