CWEB is a computer programming system created by Donald Knuth and Silvio Levy as a follow-up to Knuth's WEB literate programming system, using the C programming language (and to a lesser extent the C++ and Java programming languages) instead of Pascal.
Like WEB, it consists of two primary programs: CTANGLE, which produces compilable C code from the source texts, and CWEAVE, which produces nicely-formatted printable documentation using TeX.
Features
- Can enter manual TeX code as well as automatic.
- Make formatting of C code for pretty printing.
- Can define sections, and can contain documentation and codes, which can then be included into other sections.
- Write the header code and main C code in one file, and can reuse the same sections, and then it can be tangled into multiple files for compiling.
- Include files.
- Change files, which can be automatically merged into the code when compiling/printing.
- Produces index of identifiers and section names in the printout.
