Features: globskipdots, array slice, $(<file), prefix/suffix ops, |& pipeline, negative index, indirect expansion, compgen -X, >&word redirect, vectorized strip Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Features: BASH_LINENO/FUNCNAME tracking, /dev/full device, compgen -F callback, Empty IFS with unquoted $* keeps params separate Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Features: brace expansion in declare, export+array reassignment fix, array expansion in default value (partial) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Session 54 progress: 519 to 467 SKIPs (52 removed) Features: alias expansion, BASHPID, extglob quoted metacharacters, backslash-newline in defaults, array literal variable expansion, $_ isolation, brace expansion edge cases, associative array keys. Bug fixes: printf hex escapes, argv.py unicode, word splitting, function name validation, redirect timing, case multiline matching, @q quoting format, array append syntax. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Full @p prompt expansion with various escape sequences - Case conversion with glob patterns - Fix command substitution environment isolation - Associative array variable key expansion - Various array handling improvements Progress: 519 to 465 SKIPs (54 removed net) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Fix indexed array literal evaluation: RHS values expanded first, then indices - Correct bad var ref test expectations (bash returns empty, status 0) Progress: 519 to 462 SKIPs (57 removed) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Implement nested array index [a[0]] in literals - Fix export -n to keep value while removing export attribute - Fix array element value evaluation as arithmetic - Remove 6 stale SKIP markers (tests now pass) Progress: 462 to 456 SKIPs (6 removed) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Register commands in both /bin and /usr/bin for compatibility - Update default PATH to /usr/bin:/bin (modern system order) - Fix exec prefix binding export to child processes - Fix exec-only-redirections to not persist temp assignments - Remove 6 more stale SKIP markers Progress: 462 to 450 SKIPs (12 removed) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Word splitting fixes:
- Detect ambiguous redirect when unquoted expansion produces multiple words
- Fix mixed quotes in default values: ${Unset:-"a b" c} now produces 2 words
- Fix complex default value word splitting with multiple quoted/unquoted parts
Typeset/declare append fixes:
- Support typeset s+=foo to append to undefined/existing scalars
- Support typeset s+=(d e f) to convert scalar to array
- Support typeset a+=s to append string to array[0]
- Support dynamic variable names with +=
Unset validation:
- Validate variable names (reject invalid chars like %)
Progress: 450 to 441 SKIPs (9 removed)
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Tilde expansion fixes:
- Apply tilde expansion after brace expansion (e.g., ~{/src,root})
- Fix HOME='' tilde expansion in [[ ]] edge cases (empty vs undefined)
Syntax error fixes:
- Detect unmatched single quotes in ${var%pattern}
Progress: 441 to 438 SKIPs (3 removed)
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Unset improvements:
- Support arithmetic expressions in unset indices: unset 'a[i - 1]'
- Integrate with existing arithmetic evaluation infrastructure
Word expansion improvements:
- Fix word joining with ${arr[@]} and $@ in mixed contexts
- Properly concatenate boundary words between word-producing expansions
- Fixes dynamic flag in array assignments and extglob with arrays
Progress: 438 to 434 SKIPs (4 removed)

Major fixes include: extglob negation, declare -a clearing, case conversion with patterns, SHELLOPTS/BASHOPTS, sparse array slicing, shopt -o, rmdir command, FD move closing, set output ordering, declare -p filtering, regex handling improvements, read builtin fixes, redirect improvements, unset scoping, parser fixes for braces and backticks, division by zero handling, and many more. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
…oved) Additional fixes: - set -o verbose mode implementation - Invalid token syntax error detection - Subscript on nameref pointing to array element validation - Single quotes in arithmetic expansion error handling - Shell initialization with unset PWD using realpath - read -a with empty IFS produces empty array - Empty nameref with nounset error handling - Empty nameref assignment edge case handling Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Additional fixes: - Nameref assignment to associative array elements - Indirect array expansion with suffix operators - Associative array key-value sequence initialization - Array as associative array key coercion - Extglob patterns with IFS field splitting - Variable expansion in extglob file glob patterns Session 56 total: Reduced SKIP markers from 431 to 342 (89 removed) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Fixes: - Quotes in array index (single quotes now error, double quotes work) - Redirect with $@ expansion (ambiguous redirect error) - Readonly variable assignment stops same-line execution - Side effects in brace expansion (each expansion evaluates separately) - Regex special chars, multiple groups, = and parentheses - Typeset output format uses $'..' for newlines - Variable expansion inside nested extglob patterns - Security restrictions for command substitution in arithmetic/unset - Tilde expansion on RHS of =~ escapes regex chars - User scripts in PATH now executable (command shadowing) - Stderr warning format for assoc array bare values - Removed stale SKIP markers for user script execution tests Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Fix brace expansion to evaluate side effects per alternative (e.g., {a,b,c}-$((i++)) now outputs a-0 b-1 c-2)
- Make readonly variable assignment a fatal error (matches dash/mksh/POSIX)
- Fix ambiguous redirect detection for "$@" expansion
- Fix double-expansion bug in redirect targets with side effects
- Remove 3 SKIP markers: brace-expansion side effects, readonly one-line, $@ redirect
- Add OK bash annotations for stricter readonly behavior in several tests
Session 57: 336 -> 333 SKIP markers (3 removed)
