Gema is described as 'General purpose text processing utility based on the concept of pattern matching. In general, it reads an input file and copies it to an output file, while performing certain transformations to the data as specified by a set of patterns defined by the user' and is an app. There are more than 10 alternatives to Gema for a variety of platforms, including Linux, Windows, Mac, BSD and Haiku apps. The best Gema alternative is Perl, which is both free and Open Source. Other great apps like Gema are AWK, GNU sed, PP - A generic Preprocessor and GNU M4.
Perl is a high-level, general-purpose, interpreted, dynamic programming language with over 22 years of development.
Perl is the most popular Windows, Mac & Linux alternative to Gema.
Perl is the most popular Open Source & free alternative to Gema.
If you are like many computer users, you would frequently like to make changes in various text files wherever certain patterns appear, or extract data from parts of certain lines while discarding the rest.
sed (stream editor) is a Unix utility that parses text and implements a programming language which can apply transformations to such text. It reads input line by line (sequentially), applying the operation which has been specified via the command line (or a sed script), and then...
P is a text preprocessor designed for Pandoc (and more generally Markdown and reStructuredText). PP implements:
GNU M4 is an implementation of the m4 macro preprocessor. Developed by the GNU Project, GNU M4 is designed to avoid many kinds of limits found in traditional m4 implementations, such as maximum line lengths, maximum size of a macro and number of...
The C preprocessor implements the macro language used to transform C, C++, and Objective-C programs before they are compiled. It can also be useful on its own.
filepp is a generic file preprocessor. It is designed to allow the functionality provided by the C preprocessor to be used with any file type. filepp supports the following keywords, all of which have their usual C preprocessor meanings and usage.
TXR is a pragmatic, convenient data munging language oriented toward processing of text from files or streams, using multiple programming paradigms. It is influenced by concepts from text processing languages such as awk or perl, pattern matching concepts from logic/AI...
Programming language for symbolic computation with extraordinary combination of pattern matching features: tree patterns, associative patterns and expressions embedded in patterns.
GPP is a general-purpose preprocessor with customizable syntax, suitable for a wide range of preprocessing tasks. Its independence from any one programming language makes it much more versatile than the C preprocessor (cpp), while its syntax is lighter and more flexible than...
A variation on the C preprocessor that (1) works on multiple languages and (2) encodes preprocessor statements as comments in that language so syntax correctness is not broken.
The build preprocessor is similar to the C preprocessor, meant for processing files which have no built-in preprocessor such as XUL and JavaScript documents.
