- File languages/doctools/tests/sf/result/var-ref-007 — part of check-in [ea5192243e] at 2018-08-21 23:51:07 on branch language-doctools — Brought part of the `mindt` example, and associated experiences into the doctools example. Reworked the doctools grammar to properly handle the special forms. Further reworked to give it a structure similar to the `mindt` grammar. Started updating the tests. Oops! There is strong ambiguity in the innards of `tclword`, the G1 level sub-structuring of command arguments. It happens because at G1 level we have invisible whitespace discards, and so a text like `BBB CCC` can be parsed as two separate `unquoted` arguments (good), or as a __single__ `unquoted` argument of two elements (bad) because the spacing separating them went away at L0 level. Something similar happens in the definition for `quoted`. `braced` is fine because it maps to a single unbroken lexeme. This needs more thought ... Currently I only see bringing the argument spacing into the G1 as possible solution. The lexeme match would have precedence over the discards. Oh, and `quoted` already has `space` as element of the structure, so maybe it would not have the issue. That would be similar to the special forms, they handle their inner whitespace explicitly too, although in L0. ... A quick trial looks to be working ... Only forest remaining looks to be `breaker` vs `space` in example blocks. Fixed the ambiguity as well. Introduced non-breaking (nb) space, allow only that in the example text. Use non-breaking simplex variants as well to gather longer chunks of input. This looks good. Tests all ok, and ASTs look good enough. I may introduce the special action `::evens` however to drop unwanted spaces in the `tclwords` sub-tree. Explicit removal of the separators. Tests/examples for variable handling and includes have priority tough. Also, get larger/real-world examples (Tcllib, Critcl, Kettle, Kinetcl, etc). (user: andreask size: 138) [more...]
