| * zc: add the defer statementGravatar zinc 13 days1-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | defer expr; and defer { ... } register code that runs when the enclosing block ends: at the end of the block, and at return, break and continue that leave it. the tokens are kept at the defer and compiled again at each exit (block_close, body, kw_return, kw_break, kw_continue), newest first, before the block's variables are released, so the analyzer sees a deferred rt.free(p) as the transfer of p where it runs. names mean what they meant at the defer; values are read when it runs. return, break and continue inside a deferred statement are errors, reported once. works in unchecked code and closures (own base per function context).
* | fix std hover, full capture terminator, bare static calls, void main in ↵Gravatar zinc 13 days1-2/+2
|/ | | | | | | | | | | | | run-only images - hover: a symbol from an embedded library source (tinyvm:std.zc, tinyvm:icon.zc) was looked up only in the document; look it up by its qualified name in the library source (hover_embedded_sym), and render a method found that way by its line (bs_hover). - std.capture: allocate one word more than the 256 it holds, so end() terminates inside the buffer. - a bare call to a static function of the enclosing struct resolves like a bare struct constant (mstruct is set for every non-generic struct's methods); the struct's own wins over a global. - run.zc declares main untyped (fn main();), so a run-only image accepts int, void or untyped main with both compilers.
* docs: add SPEC.md, the first written specification of zcGravatar zinc 13 days1-0/+1093
Reference for lexing, types, expressions (full precedence table), statements, declarations, the ownership analyzer and its messages, compile-time execution and the runtime contract, with appendices for the zc0 subset and for doc/implementation disagreements and bugs found while checking the rules against build/bin/zy. Pointers added to README.md and ONBOARD.md.
