GoAWK is a POSIX-compatible version of AWK, and additionally has a CSV mode for reading and writing CSV and TSV files.
The project has a good suite of tests, which include the developer’s own interpreter tests, the original AWK test suite, and the relevant tests from the Gawk test suite.
This is free and open source software.
Key Features
- Proper support for CSV and TSV files (read the documentation).
- Code coverage feature.
- Supports negative field indexes to access fields from the right, for example, $-1 refers to the last field.
- Embeddable in your Go programs! You can even call custom Go functions from your AWK scripts.
- Most AWK scripts are faster than awk and on a par with gawk.
- The parser supports ‘single-quoted strings’ in addition to “double-quoted strings”, primarily to make Windows one-liners easier when using the cmd.exe shell (which uses ” as the quote character).
