This standard includes besides many accented letters the Edh, > Eng and Thorn. It does *not* include Open E, Open O and variant B, which are > widely used in african writing (not to mention those letters occurring in > only a few languages). So, if you want to use TeX for typesetting african > languages, you will have to prepare your own fonts. We put accented letters used in European languages into the proposed standard because: 1) We want TeX to hyphenate words with accented letters correctly. 2) We want correct kerning for accented letters. 3) We want the accents to be correctly placed and shaped. You can't do this with the \accent primitive. We know this standard only supports the major European languages. We'll need other font standards to support other languages or groups of languages (or a new version of TeX that supports a character set larger than 256 characters).

Being somewhat low on funds, I am not real anxious to buy it unless I must. Is there any freely available summary of the differences between the old and new editions/printings? David ---------------------------------------------------------------------------- Date: Sat, 22 Sep 90 00:59:07 EDT From: gabriele@riverdale.toronto.edu (Mark Gabriele ) Subject: Help with Strange sort of Tabular environment Keywords: LaTeX, tabular I am attempting to coerce LaTeX into drawing a 2-dimensional matrix which has labels on the rows *and on the columns*. The appearance I wish to achieve is this: / / / / / / / / / / / / / / / / / / / / / / / / / --------------------- row 1 name | | | | | --------------------- row 2 name | | | | | --------------------- row 3 name | | | | | --------------------- ...etc. Where the areas represented by "/" should actually be the text which labels the columns. The text should be ascending at an angle of about 60 degrees elevation from the horizontal. Can anyone suggest a way to do this? Thanks in advance. =Mark (gabriele@hub.toronto.edu) ------------------------------------------------------------------------------- Date: Mon, 1 Oct 90 15:26:32 EDT From: guy@phy.duke.edu (Guy Metcalfe) Subject: \lefteqn inside eqnarray environment Keywords:\lefteqn, eqnarray environment > FLEQN style option. Is there a way to just move the first line to the > left margin of the page? I wrote out an integral table (using LaTeX) where the first line was outdented to the left. I used fleqn.sty and redefined the \mathindent parameter to 2em and stuck in an \hspace for the third equation line because I thought it looked good. It doesn't put the first line of the equation to the left text margin (as you wanted), but it does put it to the left margin of the indented equation environment. I suppose you could redefine the equation indentation to zero, if you liked. Hope this helps.

Program text is set in a Roman font, comments in slanted, and strings in typewriter. Operators such as <= are optionally combined into single symbols like $\le$. Keywords are *not* emphasised---I find this ugly and distracting. (By purest coincidence it would also be very hard to do.) These macros can be \input in plain TeX or used as a style file in LaTeX. They provide a convenient alternative to tgrind, particularly for program fragments embedded in documents. Full instructions for use appear in the macro package itself. \'Eamonn McManus <emcmanus@cs.tcd.ie> <emcmanus%cs.tcd.ie@cunyvm.cuny.edu> ASCII: !"#$%&'()*+,-./09:;<=>?@AZ[\]^_`az{|}~ % cprog.tex (or cprog.sty) - formatting of C programs % By \'Eamonn McManus <emcmanus@cs.tcd.ie>. This file is not copyrighted. % $Id: cprog.tex,v 1.4 90/09/12 23:21:26 emcmanus Exp $ % This allows C programs to be formatted directly by TeX. It can be % invoked by \cprogfile{filename} or (in LaTeX) \begin{cprog} ... % \end{cprog} or (in plain TeX) \cprog ... \end{cprog}. In LaTeX, the % alternative form \begin{cprog*} is allowed, where spaces in C strings % are printed using the `square u' character (like LaTeX {verbatim*}). % In plain TeX, you have to use \csname cprog*\endcsname for this (sorry). % If you are using \cprogfile, say \cprogttspacetrue beforehand if you % want this effect. % The formatting is (necessarily) simple. C text is set in a normal Roman % font, comments in a slanted font, and strings in a typewriter font, with % spaces optionally made visible as the `square u' symbol. Tabs are % expanded to four spaces (this does not look good when comments are % aligned to the right of program text). Some pairs of input characters % appear as single output characters: << <= >> >= != -> are respectively % TeX's \ll \le \gg \ge \ne \rightarrow. Say \cprogpairsfalse to disable % this. % You can escape to TeX within cprog text by defining an escape character. % The character @ is suitable for C and Pascal. I have not tested other % characters so they may interact badly with their existing definitions here. % To define @ as the escape character, do \cprogescape@. Then within text % you can do @ followed by TeX commands. These commands will be in a TeX % group with the \catcodes of \{}% as normal. The commands are terminated % by a newline, which is not considered part of the program text. % The fonts below can be changed to alter the setting of the various parts % of the program. The \cprogbaselineskip parameter can be altered to % change the line spacing. LaTeX's \baselinestretch is taken into account % too. The indentation applied to the whole program is \cprogindent, % initially 0. Before and after the program there are skips of % \beforecprogskip and \aftercprogskip; the default values are \parskip % and 0 respectively (since there will often be a \parskip after the % program anyway). % If the source text is Pascal or Modula-2, say \pascaltrue or \modulatrue % (respectively) before formatting it. This makes (* *) be recognised for % comments instead of /* */. Braces {} are also recognised for Pascal. % \pascalfalse or \modulafalse as appropriate restores the default of C. % This package works by making a large number of characters active. Since % even spaces are active, it is possible to examine the next character in % a macro by making it a parameter, rather than using \futurelet as one % would normally do. This is more convenient, but the coding does mean % that if the next character itself wants to examine a character it may % look at a token from the macro rather than the input text. I think that % all cases that occur in practice have been looked after. % The macros could still do with some work. For example, the big macro % defined with [] taking the place of {} could be recoded to use {} and so % be more legible. The internal macros etc should have @ in their names, % and should be checked against LaTeX macros for clashes. % Allow multiple inclusion to go faster. \ifx\undefined\cprogsetup % The whole file. % Define the fonts used for program text, comments, and strings. % Note that if \it is used for \ccommentfont, something will need to % be done about $ signs, which come out as pounds sterling. \let\ctextfont=\rm \let\ccommentfont=\sl \let\cstringfont=\tt % Parameters.
