rs-0.4.0#

The canonical Marslang source extension is now .mars.

Migration#

Rename your .mrs source files to .mars and update references in commands and scripts. The bundled files are now hello.mars, stdlib.mars, and docs/api/examples/strings.mars. Generated output still uses .js.

cargo run -- compile hello.mars -o hello.js
node hello.js

The CLI accepts explicitly supplied source paths without enforcing an extension, so older filenames can still be compiled. CLI help, tests, and current API documentation use .mars. Historical release notes retain their original names.

Validation#

cargo test: 55 passing tests (7 unit and 48 integration), none ignored. The renamed bundled example compiles and runs under Node, printing 3 and 78.53975. The renamed Unicode API example is covered by an execution test.

Language behavior and the limitations documented in rs-0.3.0 are otherwise unchanged.
