What I want to do is write a single file which: 1. can be directly processed to produce a formatted document, and 2. can be directly processed to produce a running program. In Haskell, one writes a plain LaTeX file where source code is marked off from the surrounding environment. Prolog, being a declarative language, allows the presentation of the different statements to be made in any order convenient for organizing the explanation -- something that can also be done with Haskell, a purely functional language. With txt2tags, one is not limited to LaTeX, of course, and this is another plus. On reading the Wikipedia entry on "Literate Programming", I see that what I seek is more properly called "semi-literate programming". Please see that article for an explanation of the difference. With that out of the way, Thanks! for your response. Although I've used Vim regular expressions for fairly complex changes, when I read "Python regular expressions" the beginning of line ^ didn't come to mind. I'm somewhat embarrassed. Also, I'd missed the %%% comment blocks in 2.5. Now with your answer setting my mind in motion (hopefully), it appears that I can get pretty much what I want by using the preprocessor fairly simply together with a little source code discipline with almost any language. > > ... > > Question: Using the current built in preproc filter, can one just set the > > first % in a line to "", and thus eliminate the need for a separate > > pre-process filter? > > > yes of course: > %!preproc: "^%" "" > ^ stand for the beginning of the line in python regular expressions. > > My goal would be to not have to pre-process the source code file, since in > > development there may be many compile-test-compile-test-compile-test > > cycles. > > > > Maybe it is not related to your question, but do not forget the %%% mark > that delimits a commented section in txt2tags.
