Rex v0.6.0

Rex 0.6.0

Rex 0.6.0 expands the standard library, tightens several compiler checks, and clarifies the current path toward Rex 1.0.

Highlights

Standard library

• Added rex::process
  • process.run(&command) -> Result<num, str>
  • process.capture(&command) -> Result<(num, str), str>
• Added rex::url
  • url.parse(&url) -> Result<Map<str, str>, str>
  • url.encode_component(&text) -> str
  • url.decode_component(&text) -> Result<str, str>
  • url.join(&base, &part) -> str
  • url.with_query(&base, &params) -> str

Compiler and diagnostics

• Generic bounds are now validated more strictly at call sites.
• Multi-tag match arms that attempt to use bindings now fail with a clear parse error instead of being accepted in a broken state.
• Internal method dispatch generation was tightened for nested member calls.
• http.get_status now matches its documented return shape more closely.

CLI and release workflow

• Added explicit CLI version reporting:
  • rex version
  • rex --version
  • rex -v
• Added rex check-update to compare the local CLI version with the latest published release.
• Clarified the distinction between:
  • the Rex CLI/language version
  • the project version written to rex.toml

Documentation

• Updated standard library documentation for the new modules.
• Added new examples for process and url.
• Reworked the roadmap and spec notes to make the current pre-1.0 direction explicit.

Notes

This release does not introduce new core syntax. The focus of 0.6.0 is standard library growth, stronger diagnostics, and a cleaner path toward a stable 1.0 baseline.

Direction toward Rex 1.0

The goal remains a disciplined Rex 1.0 release with a stable core surface, clearer version semantics, stronger compiler guarantees, and a more complete standard runtime. Rex 0.6.0 is an incremental step in that direction, not the final freeze point.
