deweb - strips away C & CWEB commands from CWEB sources
[ file1 file2 ...
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
or spell-checkers like ispell.
tool, included in the ChkTeX
distribution will do just
this; writing similar scripts should be trivial.
strips away the C code from your CWEB source, it tries to
preserve line breaks. This means that the error reports from <your
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
which output is truly difficult to figure anything out from).
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
theoretically, this should work. This would ease the debugging
of the LaTeX
code significantly, as when LaTeX
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.
should now understand all correct CWEB
opcodes. If it
complains about not understanding a correct opcode, please inform the author.

Doesn't even compile
versions before perl v5.
Unfortunately, this means that we can't even tell the user why we failed;
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.
