File templates are automatically expanded when opening empty files who match one
of the rules in the ~+file-templates-alist~ variable.

These templates are simply yasnippet snippets, which can also be expanded by
typing their trigger and pressing [[kbd:][TAB]]. By convention, the triggers for file
templates are prefixed with two underscores ~__~ (the trigger for the default
file template of a major mode is almost always ~__~).

** Inserting OSS licenses
A special command is available for inserting software licenses: ~M-x
+file-templates/insert-license~.

#+begin_quote
 📌 Licenses with a ~-bp~ suffix are boilerplate templates; i.e. shorter
    versions intended for comment headers in code files.

** Adding new or changing existing file templates
New file templates can be added to
=$DOOMDIR/snippets/{major-mode}/{snippet-name}=. The yasnippet documentation
covers [[https://joaotavora.github.io/yasnippet/snippet-development.html][how to write a snippet]]. You can map a snippet to a file path, major mode,
or another arbitrary predicate using [[fn:][set-file-template!]].

Look into its documentation with [[kbd:][<help> f set-file-template\!]].

** Adding new OSS licenses
Add snippet files to =$DOOMDIR/snippets/text-mode/= with the =__licenses-=
prefix and [[fn:][+file-templates/insert-license]] will recognize them. E.g.
=$DOOMDIR/snippets/text-mode/__license-mit=.

* Troubleshooting
- If a file template isn't expanding where you expect it to, run ~M-x
  +file-templates/debug~. This will report to you what file template rule would
  apply for the correct file.
