This archive contains OS/2 and DOS versions of LaCheck, a "lint"
for LaTeX (see below). New files:
./
lacheck.exe OS/2 1.x--2.x and DOS executable
lacheck-32.exe OS/2 2.x executable
lacheck.1 man-page (see text version below)
src/
makefile.os2 makefile for EMX/gcc 0.8g and MSC 6.00A
lacheck.def linker-definition file
lacheck-32.def
The 32-bit OS/2 executable will need the DLLs from the EMX distribution.
These are currently available as

LaCheck is a tool for finding potential errors in LaTeX documents.
LaCheck catches many errors LaTeX will ignore, and LaCheck generally
gives better error messages. Think of it as lint for LaTeX. However,
it may also give warning for correct documents.
LaCheck should work on any Unix system that `flex' has been ported
to. It may also work on other systems, I wouldn't know. In
particular, no DOS binary of this version is currently available, and
I cannot create one. LaCheck is available for anonymous ftp from:
host: ftp.iesd.auc.dk
file: /pub/TeX/LaTeX/lacheck.tar.gz
New in this version is check for italic correction:
alpha% cat test.tex
{\it Say {\sl goodbye {\em evil, cruel\/} world\/}\/}.
alpha% lacheck test.tex
"test.tex", line 1: you may need a \/ before "evil"
"test.tex", line 1: \/ not needed after non-italic text " cruel"
"test.tex", line 1: \/ not needed before italic text "world"
"test.tex", line 1: double \/ found "\/"
"test.tex", line 1: do not use \/ before "."
Also line numbers should be more correct in this version.

NAME
LaCheck - A consistency checker for LaTeX documents.
SYNOPSIS
lacheck filename [ .tex ]
DESCRIPTION
LaCheck is a general purpose consistency checker for LaTeX
documents. It reads a LaTeX document and displays warning
messages, if it finds bad sequences. It should be noted,
that the badness is very subjective. LaCheck is designed to
help find common mistakes in LaTeX documents, especially
those made by beginners.
The things checked are:
Mismatched groups (braces), environments and math mode del-
imiters. When a mismatch is found, line numbers for both
start and end of the mismatch is given. The error messages
comes in pairs, one for the end match and one for the begin-
ning, marked with `<-' and `->' respectively.
Bad spacing including missing a `\ ' after an abbreviation,
missing an `\@' before a punctuation mark in a paragraph
that is ended by an capital letter, double spaces like ` ~',
bad usage of ellipsis (like using ... instead of \ldots, or
using \ldots where \cdots should be used), missing ~ before
a \cite or \ref commands, space before footnotes, italic
corrections before comma, point, or italic text, italic
correction after normal text, missing italic correction when
switching from italic to normal text, and double italic
correction.
Badly placed punctuation marks around end of math mode del-
imiters. This is, pucktuators placed right after display
math end or punctuators placed right before text math end.
Sequences of whitespace followed by punctuation marks are
also caught.
Bad use of quotation characters, i.e. constructs like
"'word" or "word`" are warned about, tabs in verbatim
environments are caught, certain TeX primitives are frowned
upon, attempts to give font specifiers arguments such as
\em{text} are noted, and use of @ in LaTeX macros are
reported.
LaCheck will read files that are input using \input or
\include. Files with suffix `.sty' are omitted, as they
probably will cause LaCheck to crash.
LaCheck may be invoked from within Emacs(1) using compile:
To run: M-x compile RET lacheck RET , and then C-x ` to
parse the messages
OUTPUT
The output is UNIX-error like, and may be parsed using
Emacs(1) compile mode. Here is a sample:
lacheck compiler
"/usr/mef/compiler.tex", line 34: missing `\ ' after "etc."
"/usr/mef/compiler.tex", line 179: double space at " ~"
"/usr/mef/compiler.tex", line 186: <- unmatched "}"
"/usr/mef/compiler.tex", line 181: -> unmatched "$$"
A control space `\ ' should be inserted at line 34, to
prevent an end-of-sentence space. Also, at line 179, the
first space of the sequence " ~" should probably be deleted.
The last two lines is an example, where the user mistyped,
and probably inserted an extra "}" somewhere.
DIAGNOSTICS
Some special cases should be explained. In cases where a
sentence ends with something that LaCheck thinks is an
abbreviation an missing `\ ' error may also occur, if the
following sentence begins with a lowercase letter.
A mismatch error may cause more to follow, due to the chosen
algorithm. In such cases just correct the first error and
run LaCheck again
Braces, environments and math mode must be balanced within a
file.
LaCheck may be confused by unmatched stuff placed inside
verbatim-like environments called something else than
exactly `verbatim'.

BUGS
LaCheck gets confused by advanced macros, is fooled by sim-
ple macros, can't figure out if you use a non-standard way
to switch italic on or off, does not like TeX at all, does
not provide any options to turn off specific warnings, and
is at best a crude approximation.
Ideas for improvements and bug reports are very welcome.
Such should be directed to the maintainers, their email
address is <auc-tex_mgr@iesd.auc.dk>.
