2026-01-07fix: set 'HasInit' token property in language definitionMarc Vertes
2026-01-06fix: correct and simplify parsing of expressions.Marc Vertes
The expressions were parsed from right to left, and it was incorrect and cumbersome. Now they are processed from left to right, with a simpler and correct handling of precedence rules. The vm function call syntax has been changed to set the function before the input arguments on the stack, as to follow the declaring order in languages.
2025-11-27fix: improve parser, compiler and interpreter APIsMarc Vertes
Pass a language spec as an argument when create a new parser, compiler or interpreter. Also move the REPL code in interpreter package.
2024-04-02chore: add linters and some lint fixes (#8)Marc Vertes
* chore: add linters and some lint fixes Configure some golangci-lint linters to get the code quality right. Apply the first fixes. Next step will be to add github actions to run lint and tests in github CI. * chore: more lint, fixed comments and variable names. no semantic change. * chore: add Makefile This makefile is intended to be used as a local substitute to github actions.
2023-10-21parser: implement operator precedence rules in expressionsMarc Vertes
2023-10-12move to a direct byte code compiler (#8)Marc Vertes
* chore: refactor to keep only the new parser and bytecode vm * scanner: remove Token.value field * scanner: remove scanner.kind field * chore: move language specification in lang package This avoid a cyclic dependency in scanner_test which can now use the golang/GoSpec language specification for Go. * clean code * scanner: export scanner fields Also parser now generate function calls, including externals. * chore: fix lint issues * parser: handle strings * wip * parser: implement support for 'if, else, else if' statements Resolving labels in the compiler still in progress. * parser: support if statements, improve compiler * improve handling of functions * improve support of local variables * scanner: trim leading and trailing spaces * fixes to make fibonacci work * parser: improve README, fix function parameters parsing
