catdvi can be used to transform TeX DVI files into text, losing
|
||||
formatting its main aim on SBo is to be used by recoll, when it cannot
|
||||
extract text from pdf files by other means.
|
||||
|
||||
|
||||
catdvi is a program that translates TeX Device Independent (DVI) files
|
||||
into readable plain text. The program is under development. It
|
||||
produces satisfactory results in many cases, but still has some issues
|
||||
with complicated input.
|
||||
|
||||
Goals Actually, "translate to plain text" can mean several different
|
||||
things, depending on the intended use:
|
||||
|
||||
Output formatted text that resembles the layout of the DVI file as
|
||||
closely as possible, suitable for e.g. preview on a character cell
|
||||
terminal or printing on a teletype style printer. Output unformatted
|
||||
text in "read order". (Rather than "print order", which makes quite a
|
||||
difference with e.g. multi-column page layouts). Useful for searching,
|
||||
indexing and other kinds of postprocessing, and maybe also for export
|
||||
to different text processors. Output (not completely plain) text in
|
||||
read order with the formatting distilled into some kind of markup so
|
||||
that paragraph breaks, subscripts, superscripts, etc. can still be
|
||||
recognized. This functionality is essentially a (La-)TeX decompiler,
|
||||
useful for recovery of lost or otherwise unavailable .tex files.
|
||||
catdvi's principal target is to create human-readable text files from
|
||||
DVI input, and hence the first kind of translation.
|
||||
|
||||
The second kind is supported as well because one of the developers
|
||||
needed it and it could be obtained as an easy by-product (based on the
|
||||
mostly true assumption that read order = order in the source file =
|
||||
order in the DVI file).
|
||||
|
||||
The third kind of translation is the most difficult one to achieve
|
||||
since a DVI file does not contain logical markup information. The
|
||||
structure of the text has to be guessed from heuristic principles and
|
||||
an analysis of certain characteristics of TeX's output. No attempt in
|
||||
this direction has been made so far. But knowledge of some aspects of
|
||||
text structure would also help to improve the quality of layout in
|
||||
case 1. If it turns out these can reliably be guessed, an option to
|
||||
show them as markup will probably follow. This feature has low
|
||||
priority at the moment, especially since nobody has expressed a need
|
||||
for it.

# HOW TO EDIT THIS FILE:
|
||||
# The "handy ruler" below makes it easier to edit a package description. Line
|
||||
# up the first '|' above the ':' following the base package name, and the '|'
|
||||
# on the right side marks the last column you can put a character in. You must
|
||||
# make exactly 11 lines for the formatting to be correct. It's also
|
||||
# customary to leave one space after the ':'.
