Set Delimiters `{{=<% %>=}}`

Status: Not supported. Not planned: most defensible "won't fix" of the optional categories.

Summary​

Mustache lets a template change the open/close delimiters mid-stream: {{=<% %>=}} switches from {{ }} to <% %> for the rest of the template (or until the next set-delimiter tag). Bigodin's parser hard-codes {{ / }} and provides no mechanism to switch.

delimiters.json is in SKIPPED_SPECS (test/spec.spec.ts); its 14 tests count toward the file-level skip total in the overview. Bigodin's existing {{= ...}} syntax is variable assignment (e.g. {{= $foo expression}}), not set-delimiters; the two share a leading = and would need to be disambiguated if set-delimiter support were added.

Why not planned​

Three reasons stack:

  • Real-world demand is minimal. Handlebars itself does not ship set-delimiters, and Bigodin is positioned as a Handlebars-flavored superset.
  • The parser is combinator-based. pierrejs parsers are pure functions; there is no built-in mutable parser state. Implementing delimiter switching cleanly requires either a preprocessing pass that rewrites the source (with a location-map so error messages still point at the right column) or threading delimiter state through Pr.context and rewriting openMustache / closeMustache / text. Both options are large surgeries on a stable parser.
  • Disambiguation cost. The = branch in the parser today is assignment. Adding a set-delimiter meaning means context-sensitive parsing (e.g. {{= followed by $ is assignment; {{= followed by anything else is a set-delimiter). Easy to get subtly wrong.

The combination - low demand, high implementation cost, and a brittle disambiguation - makes this the strongest "won't fix" candidate of the optional categories.

Workaround​

Pick a different templating tool if you need this feature; Bigodin will not be it. If you only want to escape literal {{ / }} inside a template, the standard approach is to wrap the literal text in a helper or in a configured raw escape sequence rather than to repurpose the delimiter syntax.
