deweb - strips away C & CWEB commands from CWEB sources
Contents
Bugs
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.
7th Edition June 8, 1996 deweb(1)
Description
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 <yourfavoritetool> 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.
