The VM Vassign instruction now takes an argument to indicates the
number of assignations to perform on the stack.
Definitions with a function returning multiple values now work.
There is still some simplifications, and also to apply the same
strategy to var declarations with assign.
fix: improve multi assign2026-01-26T17:44:29ZMarc Vertesmvertes@free.fr2026-01-26T17:44:29Zurn:sha1:aa5861917ac2543f85bf4cfefbb69cf501d4de41
Do not consider assign operators in expression handling, they are
part of statements.
Isolate parsing of left hand side and right hand side in assignments.
feat: add Next2 and Pull2 instructions in vm.2026-01-23T12:05:10ZMarc Vertesmvertes@free.fr2026-01-23T12:05:10Zurn:sha1:3113c7f058e427c49e936f82a518766ddb869c58
These will be used for range clause assigning both key and value.
feat: make Next iterator instruction faster and more efficient2026-01-23T10:16:12ZMarc Vertesmvertes@free.fr2026-01-23T10:16:12Zurn:sha1:2837dabf7818666a9366d659d2da3b9055140740
Branching control is delegated directly to the Next instruction,
which now takes the location of loop exit as first argument.
It avoids the use of JumpFalse, plus the stack storage for the
condition.
chore: make Compiler.emit a method instead of closure2026-01-23T08:37:11ZMarc Vertesmvertes@free.fr2026-01-23T08:37:11Zurn:sha1:abd8581bac36018be2f090e05fdd00ea74f6ca4bchore: use parser.Token.Arg to store generated parameters2026-01-23T08:23:51ZMarc Vertesmvertes@free.fr2026-01-23T08:23:51Zurn:sha1:79eaad4bbb778b04501fca724ce2641e25b33f3achore: use token helpers2026-01-22T22:22:46ZMarc Vertesmvertes@free.fr2026-01-22T22:22:46Zurn:sha1:9e4a84f78283f9b5a972245076b26da312490ff0chore: refactor token types to avoid mutate scanner tokens2026-01-22T10:33:32ZMarc Vertesmvertes@free.fr2026-01-22T10:33:32Zurn:sha1:9bf668e7114bb92a0b072db5d4e092c0b8f964c4
Mutating scanner tokens or reusing scanner token attributes to
store other metadata is a hack. Introduce a new parser token
type with arbitrary args. The next step will be to use the arg
field instead of scanner token fields.
feat: add support for range clause and iterators2026-01-21T18:26:42ZMarc Vertesmvertes@free.fr2026-01-21T18:26:42Zurn:sha1:c922c797204069f42a7abf88500c5708f68a8e43
- vm: added Pull, Next and Stop instructions, to implement iterators
- lang: add Range, Next and Stop tokens
- parser: handle range clause. Still naive and incomplete.
- comp: generate iterator instructions from range clause.
Work in progress. Only initial support for slices. Many more tests
and combinations needed, but the main pattern is there now.
