v0.3.0 — 2024-03-26

In this version the main executable has been renamed to normalizer and several commands have been implemented for normalization, dataization, and reporting.

New:

• Command Line Interface:
  • Add commands:
    • normalizer transform to perform normalization without executing any atoms (was default behavior before)
    • normalizer metrics to compute metrics of a given φ-expression (see #153)
    • normalizer dataize to run partial evaluation of φ-expressions with atoms (see #187)
    • normalizer report to generate report based on the results of testing against the EO compiler (see #213)
  • Add --single flag (see #131)
  • Add --json flag for machine-readable output format (see #143)
  • Add --max-depth=N and --max-term-size=N options to control limits for the normalizer (see #173)
  • Improve --chain option to provide better elaboration on the applied normalization rules and the dataization process (see #195)
• Update rule set for φ-calculus (see #152 and some changes in #136 and #166)
• Add property-based and regression tests for confluence (see #136 and #166)
• Tests and metrics against the EO compiler and standard EO test suite (see #98, #191)

Fixes:

• Count metrics, including dataless objects, correctly (see #142, #193, #211)
• Fix metavariables in context patterns (see #174)
• Support empty Δ-bindings (see #184)

Documentation has been improved (see #134, #221).

Maintenance:

• Run CI on all pull requests (see #156)
• Downgrade Stackage snapshot (see #146)
• Add HLint to CI (see #157)

v0.2.0 — 2024-02-16

• Complete implementation of Yegor's rules (see #109, #112)
  • Support global counter in user-defined rules (see #105)
  • Context matching (global object and this object, see #99)
• Fix grammar for \(\varphi\)-calculus (see #97 and #127)
• Improve documentation:
  • Set up wesbite for documentation (see #104, #124, and #128)
  • Update CLI documentation (see #113)
• Improve command line interface:
  • Support --output/-o command line option (see #92)
  • Remove logs from default output (see #106)
• Allow collection of metrics for \(\varphi\)-terms (see #121)
