v6.63.0

v6.63.0 — corpus expansion, transpiler improvements, linter hardening

- Corpus: 97.0/100 A+ score, +5400 entries (17,882 total)
- Makefile emitter raw output mode
- Nested __if_expr lowering for let-assignment and return
- Parser println! macro fix for escaped quotes
- SEC001/SEC002 linter improvements
- Comprehensive complexity refactor in parser.rs

v6.62.0 — Variable shadowing, 15,106 corpus entries

Fixed

• Variable Shadowing in Loops (P0): save/restore pattern for let-bindings
• 80 corpus failures eliminated (97.0 → 97.5 A+)
• Lexer panic on bare heredoc
• Pipe-in-condition parser (#133)
• Dynamic array indexing with runtime variables
• For-in array expansion

Added

• 819 new corpus entries (Rounds 21-37 + 20 shadow pathological)
• 15,106 total entries, 97.5/100 A+, 0 failures

Install

cargo install bashrs --version 6.62.0

v6.61.0 — 2 P0 Transpiler Fixes + 14,712 Corpus Entries

Highlights

Transpiler Bug Fixes (P0)

Two critical correctness bugs fixed in the Rust-to-Shell transpiler:

1. Return-in-loop: return expr inside while/for/match bodies within functions was emitting debug format strings (Arithmetic { op: Add, ... }) instead of shell arithmetic ($((expr))). Root cause: loop/match bodies were not propagating function-context awareness for return handling.

2. Match-in-let: let x = match y { 0 => a, 1 => b, _ => c } was producing x='unknown' instead of a proper case statement with per-arm assignments. Root cause: the parser represents match-as-expression as Expr::Block([Stmt::Match{...}]), which had no handler in convert_expr_to_value.

Both bugs were silent — the transpiler succeeded but generated incorrect shell code.

Corpus Expansion

• 14,712 total entries (13,397 Bash + 695 Makefile + 620 Dockerfile)
• V2 Score: 97.5/100 (A+), 0 failures
• 107+ CLI subcommands for corpus analysis, quality gates, and convergence tracking

New Example

cargo run --example transpiler_demo — 7 self-verifying demonstrations:

• Basic functions with return values
• Nested function calls: f(g(h(x)))
• Match expressions in let bindings
• While loops with early return
• Match inside loops (combined pattern)
• Recursive functions (fibonacci)
• Multi-function programs (gcd/lcm)

Documentation

• New Transpiler chapter in The Rash Book (overview + corpus testing)
• Updated README with current quality metrics
• Updated book version references

Upgrade

cargo install bashrs --version 6.57.0

Full Changelog

• fix(validation): context-aware exec() string validation (Refs #95)

v6.56.0

v6.56.0 - Issue Triage Release

Closes 15 GitHub issues with verified fixes:

- **#125**: SC2062 now skips SSH remote command strings
- **#97**: SEC010 recognizes custom validation functions
- **#96**: Heredoc quoted delimiters, find -name patterns
- **#95**: SC2154 with sourced files
- **#93**: Inline if/then/else/fi, SC2031/SC2125/SC2317
- **#118**: MAKE003 quoted context
- **#103**: Parser array syntax (local arr=(), arr+=(), >&2, &>/dev/null)
- **#102**: SC2128/SC2199 local scalar false positives

- **#94**: Rust→Shell transpilation deferred to v3.0+

Full test suite passes (9,872 tests)

v6.55.0 - Fix SC2128, SC2031, SC2154 False Positives

What's Changed

This release fixes several false positive issues reported in Issue #132.

Fixed

• SC2128 False Positives: No longer flags scalar variables ending in 's' (e.g., cpu_tps, status, formats) as arrays. Now tracks actual array declarations (var=(...)) instead of using heuristics.

• SC2031 False Positives: Fixed multiple false positive scenarios:

  • Array declarations var=(...) no longer detected as subshells
  • Arithmetic grouping $(( (a - b) / c )) no longer detected as subshells
  • Parentheses inside quotes (e.g., regex (?=...)) no longer detected as subshells

• SC2154 False Positives: Variables with parameter expansion operators (${VAR:-}, ${VAR:=}, ${VAR:+}, ${VAR:?}) no longer flagged as undefined.

Quality

• All fixes include comprehensive test coverage with property-based tests
• Validated against real-world benchmark scripts
