Consider the LaTeX docs the real docs. +.SH SYNOPSIS +\fBlgrind\fR [ \fB-e\fP ] [ \fB-i\fP ] [ \fB-\fP ] [ \fB-n\fP ] [ \fB-c\fP ] +[ \fB-t\fP \fI<width>\fP ] +[ \fB-h\fP \fI<header>\fP ] [ \fB-d\fP \fI<description file>\fP ] +[ \fB-l\fP\fI<language>\fP ] [ \fB-s\fP ] \fI<name>\fP ... +.PP +.SH DESCRIPTION +LGrind formats program sources in a nice style using LaTeX(1). +Comments are placed in roman, keywords in bold face, variables in +italics, and strings in typewriter font. Source file line numbers +appear in the right margin (every 10 lines). +.PP +LGrind processes its input file(s) and writes the result to standard +output. This output can be saved for later editting, inclusion in a +larger document, etc. +.PP +The options are: +.IP "\fB\-e\fP" +process a LaTeX file for embedded code. +.IP "\fB\-i\fP" +process source code file for inclusion in a LaTeX document. +.IP "\fB\-\fP" +take input from standard input. +.IP "\fB\-n\fP" +don't boldface keywords. +.IP "\fB\-c\fP" +don't treat @, etc. specially in comments. +.IP "\fB\-t\fP" +change tab width (default 8). +.IP "\fB\-h\fP" +specifies text to go into the header. +.IP "\fB\-d\fP" +specifies the language definitions file (default is +\fB/usr/lib/texmf/tex/latex/lgrind/lgrindef\fP). +.IP "\fB\-d!\fP" +same as above, but write patched executable. +.IP "\fB\-l\fP" +specifies the language to use. +.IP "\fB\-s\fP" +shows a list of currently known languages. +.PP +If LGrind is called without parameters, a help screen will be shown. +If neither \fB\-e\fP nor \fB\-i\fP are specified, a complete LaTeX +file is produced. When no language is specified, LGrind tries to find +out the language used itself; C is used when this fails. +.SH USAGE +For example, to include a C file named \fBfoo.c\fP +into your LaTeX document, first give the command: +.IP "\fC lgrind -i -lc foo.c > foo.tex\fP" +.PP +This will generate \fCfoo.tex\fP, which will have the +pretty-printed version of \fCfoo.c\fP with a lot of LaTeX commands. +.PP +Then include \fClgrind.sty\fP as you include any other style, +namely with the \fC\eusepackage{lgrind}\fP line at +the beginning of your LaTeX document. Having done this, +within the document you can include \fCfoo.tex\fP using one of the +following commands: +.PP +.IP "\fC\elgrindfile{foo.tex}\fP" +which will simply include the file at that point +of text, and will draw horizontal lines before and +after the listing. +.PP +.IP "\fC\elagrind[htbp]{foo.tex}{caption}{label}\fP" +which will put the listing also within a figure +environment, using the float options, caption and +label you gave. +.PP +To produce a standalone LaTeX file from, say, a Yacc file: +.IP "\fC lgrind -ly bary.y > bary.tex\fP" +This uses Piet van Oostrum's \fCfancyhdr.sty\fP to make the +headers and footers. +.PP +For a more detailed explanation of these commands, refer to +\fC/usr/TeX/texmf/doc/latex/lgrind.dvi\fP. +.PP +.SH "EMBEDDED PROGRAMS WITHIN A LaTeX FILE" +(From Jerry Leichter's notes.) +.PP +Within the text of your LaTeX file, you mark groups of lines as +either text- or display-style program code: +.PP +Text style: +.TS +l l. +.fT \*C + The expression + %( + a + 3 + %) + produces 10. +.fT +.TE +prints something like: "The expression \fIa\fP + 3 produces 10." +(with "a + 3" set as a program.) +.PP +The same effect can be achieved with inline @'s. +.TS +l l. +.fT \*C + The expression @a + 3@ produces 10. +.TE +.PP +Display style: +.TS +l l. +.fT \*C + The statement + %[ + a += 3; + %] + is an example of an incrementing operator. +.fT +.TE +prints something like: +.TS +l l. + The statement + a += 3; + is an example of an incrementing operator. +.TE +.PP +Important rules: +.IP +\fC%\fP and the following character must be the first two characters on +the line to be recognized. +.IP +Put \fInothing\fR on the line after the \fC%\fR and the key character. +If you do that, LGrind will provide a default environment that will +produce an \fC\ehbox\fP for \fC%(\fP \fC)%\fP, and a \fC\evbox\fP for +\fC%[\fP \fC-\fP \fC%]\fP. If you put stuff on the line, LGrind +assumes you want to control the format completely. Doing this +requires understanding \fIexactly\fP what the code LGrind produces is +doing. (Sometimes I'm not sure I do!) +.IP +\fC%)\fP and \fC%]\fP are, if I remember right, simply ignored outside +of a code group, but any extra \fC%(\fP or \fC%[\fP produces a +warning, so a missing \fC%)\fP or \fC%]\fP is usually caught. +.PP +You can insert your own code by using a line starting with \fC%=\fP in +the program text. Whatever you enter after that is left in the +output, exactly as you typed it. It will be executed in a strange +environment, so doing anything fancy is very tricky. A macro, \fC\eLine\fP, +is provided to help you do simple things. For example, +.TS +tab (/); +l. +.fT \*C +%[ +%=\eLine{________\evdots} + a = 1; +%] +.fT +.TE +produces: +.TS +tab (/); +l. +.fT \*C + \. + \. + \. + a = 1; +.fT +.TE +.PP +(Within the program text, \fC_\fP is active and expands to a +fixed-width space. A whole bunch of macros are also defined. If you +understand how LGrind sets lines up, you can replace the 8 \fC_\fP's +with a call to \fC\eTab\fP \(em but I'll let you hang yourself on that one.) +.PP +The output of LGrind always contains exactly one output line for each input +line. Hence, you can look up line numbers in TeX error messages in your +original file, rather than in the lgrind'ed (lground?) file. (Of course, if +the problem is in the LGrind output....) +.PP +Many things are controllable by re-defining various macros. You can +change what fonts LGrind will use for various kinds of things, how +much it indents the output, whether it adds line numbers, and if so at +what interval it prints them and whether it sticks them on the left or +right, and so on. This stuff is all described in \fClgrind.dvi\fP, +though probably not very well. The default settings produce output +that looks reasonable to me, though I can't say I'm ecstatic about it. +Doing a \fIreally\fP good job would require defining some special fonts. +.PP +.SH FILES +.IP "\fC/usr/bin/lgrind\fP" +Executable +.PP +.IP "\fC/usr/doc/lgrind/lgrind.dvi\fP" +Documentation +.PP +.IP "\fC/usr/lib/texmf/tex/latex/lgrind/lgrind.sty\fP" +LaTeX style file +.PP +.IP "\fC/usr/lib/texmf/tex/latex/lgrind/lgrindef\fP" +Language descriptions +.PP +.SH AUTHORS +Van Jacobson, Lawrence Berkeley Laboratory (based on +"vgrind" by Dave Presotto & William Joy of UC Berkeley), +wrote it for TeX. +.PP +Jerry Leichter of Yale University modified it for LaTeX. +.PP +George V.
