AWK based

LAWK is the simple literate programming tool for personal usage (no collaboration features). For collaboration nanolp can be used see.

Input files are markdown, output - any one. Supports non-ASCII, Windows. Does not support spaces and other special chars in paths. Source is here.

Good feautures are:

• very clean syntax of definition, pasting, writing named chunks
• simple dependencies (awk, mkdir, rm, make) - available for Windows too
• no installation (only copy source somewhere)
• markdown input format
• no special syntax for code chunks
• ctags tag file generation (unsorted)
