I’ve implemented complete parser of POSIX Shell Command Language in LPeg . The project is not finished yet, so not used anywhere in production. However, it’s quite complex grammar with complicated rules and I haven’t run into any issue with LPeg yet, even when running it on large shell scripts. So I’d not worry about quality of LPeg, it’s really awesome library.
