algorithms style : need \starttyping with TeX and math feature
Bonjour à tous, I'm trying to white some algorithms in natural language (versus pseudo-computing langage) I need to keep some "typing" for write space (i.e. indentation of text) while being able to white TeX commands (with \xxx{yyy}) and math (like $y_u(t)$) In fact I'd like some LaTeX algorithms style like feature. I could do some recursive \startitemize...\stopitemize... but it is two much verbose, so I thought looking at the ConTeXt "typing" system Also, perhaps my request is simply an option of \startlines which keep not only the lines break, but also the first spaces of each line (in a verbatim font fors these space) Thank you for any help! -- Maurice Diamantini
A solution of my probleme could be reformule to : How can I configure the \setuptyping environment to be able to keep the normal feature of special TeX caracters like: - \ - { and } and [ and ] - $ Well I agree that it's no more "typing" any more! So a special option for \setuplines would be more appropriate? Le 24 déc. 04, à 09:07, Maurice Diamantini a écrit :

Exactly, \starttyping does exactly that what you don't want: it disables math and expansion of TeX commands.
Also, perhaps my request is simply an option of \startlines which keep not only the lines break, but also the first spaces of each line (in a verbatim font fors these space)
In plain TeX you have a command \obeyspaces (apart from \obeylines). Nevertheless, whitespaces at the beginning of line are ignored when using \obeyspaces, so you additionally need to write an escaped whitespace '\ ' or \strut at the beginning of line (I guess there's a more efficient solution for that, but I'm no expert). But if you really only need whitespace at the beginning of line, probably make something like: \def\tab{\strut\hbox to 3em{}} % or any other size instead 3em instead of using \obeyspaces and simply put \tab where you need a certain amount of white space.

Using eplain.tex you can say: \verbatim |endverbatim (note bar instead of backslash.) If you need a vertical bar in the verbatim text then just double it. Anything in between including blank spaces and lines is printed verbatim. Context used to complain about one non-critical statement in the eplain file. Actually it complains about the following statement but you can easily spot the troublemaker. Delete it and eplain works fine with Context. Latest versions of eplain may already have the fix, haven't tested them. -- John Culleton Short list of publishing/marketing books: http://wexfordpress.com/tex/shortlist.pdf

Christmas present ...
Thank you Hans for this present !! I just had to search the key to open this present, as I used an old ConTeXt version So I'm trying to switch to the texlive-2004 distribution (choosing the GUTenberg installation set) After some setup (m-bib has changed, ...) I could try your code and... *** it does exactly what I need ! *** Thank you very much ! Just a question. As you keep calling this environment "\startline" I suppose it is intended to be a standard option for "\startline" (which is a great news as I think it is quite usefull for numerous situations) But as the new version of context is not yet in the texlive-2004 (or as texlive-2005 is not yet out ;-) Would it not be a better idea to provide another environnement name to avoid conflict with the future standard startline environment? I tried to rename "startlines" to "startLines" with other hack, but it doesn't seem to be suffisant (but I didn't expect to!). Any way thank you for the solution !

no, just the same command, but with an option: \setuplines[space=on] if there is real demand for it i can always make a \definelines[lines] \definelines[Lines][space=on] Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Happy new year ! Thanks to Mojca and John, I use \startlines for the algorithms environment. In the "Algo" environment, I defined some short names command to help dealing with indent spacing (\0, \1, ..., \5) and with itemize like indent (i.e. space with the same length as "- " Here is the environment I defined. It could be better (to keep the use of it event simpler) But as the "père Noël" Hans give me a "Christmas present" (see next post) It is no more usefull! \definestartstop[Algo][ before={ \start \tx \def\H{\phantom{- }}% H for Hyphen (espace correspondant à "- " \def\0{\hskip0em} % indent 0 \def\1{\hskip2em} % indent 1 \def\2{\hskip4em} % indent 2 \def\3{\hskip6em} % indent 3 \def\4{\hskip8em} % indent 5 \def\5{\hskip10em} % indent 6 \setupinterlinespace[small] \startframedtext[ width=\makeupwidth, framecolor=blue, ] \startlines }, after={ \stoplines \stopframedtext \stop }, ] Just a "french like" algorithm \startAlgo \0 Entrée : \1 - nom de l'instance à traiter (e.g. ucp8, ...) \1 - LDS\_Limit Nombre maximum de discordances (e.g. 1 pour LDS\_1, ...) \0 Sortie : \1 - affichage des meilleures solutions primale et duale \0 Algorithme : \1 - initialisation : \2 - LDS\_Counter := 0 (nombre de discordances courantes) \2 - lecture de l'instance \2 - propagation initiale \1 - relaxation lagrangienne principale avec primalisations interne \1\H $\Rightarrow$ on connait bestDualValue, bestPrimalValue et les coûts réduits \1 - explorer le noeud racine (i.e. toutes les variables étant libres) \1 - afficher les résultats \stopAlgo Thanks you very much !
