deweb - strips away C & CWEB commands from CWEB sources
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
lacheck, or spell-checkers like
chkweb tool, included in the
ChkTeX distribution will do just this; writing similar scripts should be
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
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
LaTeX code significantly, as when
LaTeX complains about wrong syntax, youll be able to find the erroneous
line much more easily. Dont 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.

Perl versions before perl v5. Unfortunately, this means that we cant 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.
