gema is a general purpose text processing utility based on the concept of pattern matching. It reads an input file and copies it to an output file transforming the data as specified by the patterns defined by the user.
It can be used to do the sorts of things that are done by Unix utilities such as cpp, grep, sed, awk, or strings.
It can be used as a macro processor, but it is much more general than cpp or m4 because it does not impose any particular syntax for what a macro call looks like. Unlike utilities like sed or awk, gema can deal with patterns that span multiple lines and with nested constructs. It is also distinguished by being able to use multiple sets of rules to be used in different contexts.
This is free and open source software.
