General Description

This code was inspired by Henry G. Baker’s article: “Pragmatic Parsing in Common Lisp”, ACM LISP Pointers IV,2 (April-June 1991), 3-15.

However, any errors are mine; inefficencies too. There have been some minor changes and additions from the code in that article.

Original paper


  • Run ‘make’ in directory Extras/Vmeta.
  • Run ‘make test’ in directory Extras/Vmeta.


The pipe library consists of single EuLisp module:

  • vmeta.em – root module

which uses the syntax operators in vmeta-aux.em

Something went wrong with that request. Please try again.
