Implements basic sed (stream editor) and awk (pattern scanning) commands following ChrysaLisp coding conventions and architectural patterns. sed features: - Substitute command (s/pattern/replacement/[g]) - Delete command (d) - Print command (p) - Line number and pattern addressing - Range addressing - Quiet mode (-n flag) awk features: - Field splitting with configurable separator - Built-in variables (NR, NF, $0-$n) - BEGIN/END blocks - Pattern matching and conditionals - Print and variable assignment - Simple expression evaluation Both commands: - Read from stdin or files - Follow ChrysaLisp naming conventions - Use lib/text/searching for pattern matching - Include comprehensive usage documentation Test suite includes: - Sample data files - Test cases for both commands - README with examples and limitations
Fixes: - Replace filter with filter! (correct iteration primitive) - Replace get/insert with proper hmap API (def and :find method) - Use (. vars :find key) instead of undefined get function - Use (def vars key value) instead of insert for environment updates - Handle nil case in compound assignment Testing: - Add TESTING_sed_awk.md with comprehensive test procedures - Document CONTRIBUTIONS.md conformance checklist - Include manual test cases for both sed and awk - Add test runner script framework - Document known limitations The code now properly uses ChrysaLisp hmap/environment API and follows iteration primitives (filter! vs filter).
