deweb(1) strips away C & CWEB commands from CWEB sources


deweb [ file1 file2 ... ]


deweb filters away all C & CWEB commands from a CWEB source code. This leaves only the LaTeX code. This stripped code, in turn, may then be passed to a suitable syntax checker for LaTeX, like ChkTeX and lacheck, or spell-checkers like ispell.

The chkweb tool, included in the ChkTeX distribution will do just this; writing similar scripts should be trivial.

When deweb strips away the C code from your CWEB source, it tries to preserve line breaks. This means that the error reports from <your favorite tool> will be correct regarding to line numbers. In most cases, the column position will also be correct. This significantly simplifies finding the errors in the LaTeX source (in contrast to the output from cweave, which output is truly difficult to figure anything out from).

deweb accepts a list of filenames on the argument line, and will send its output to stdout. If no filenames are given, it will read from stdin, acting as a filter. No options are currently accepted.

Macho users may try to pipe the output from deweb directly into LaTeX, theoretically, this should work. This would ease the debugging of the LaTeX code significantly, as when LaTeX complains about wrong syntax, you'll be able to find the erroneous line much more easily. Don't expect that the output looks very much like the final one, though.

deweb should now understand all correct CWEB opcodes. If it complains about not understanding a correct opcode, please inform the author.

Doesn't even compile under Perl versions before perl v5. Unfortunately, this means that we can't even tell the user why we failed; Perl will just complain about not being able to compile the regexps.

The program will try to swallow the whole input file at once, instead of processing it on a line-by-line basis.
