This directory contains files that allow to generate two style files: 'programs.sty' and 'keywords.sty'. The 'demo' subdirectory contains an example of what can be done with these two styles ('demo.tex' can be compiled either with LaTeX or with LaTeX2.09 -- see the corresponding directory under macros/latex209/contrib). The two files in this archive may be used independently or in conjunction, according to your wish. The file 'programs.sty' is intended to allow a parameterized way of typesetting programs with TeX/LaTeX commands inside. The file 'keywords.sty' allows use and define sets of keywords that will be typeset with different fonts, according to the wish of the user. The purpose of these two files, when used in conjunction, is to allow a user to write only one program and to print it differently, according to the document where it must be put (ex: keywords in english/french, keywords underlined, boldfaced, programs indented, no indented, numbered, unnumbered, etc). Of course, the algorithm will be written only once. Below I give a short description of the files and the way to generate them. ------------ programs.sty ------------ I have written a style file for typesetting programs. Its particularities are: - TABS are replaced by simple SPACES as in the 'astyped.sty' style - and you can use emphasized fonts, math formulae, etc. - programs may be numbered or unnumbered - line numbers may appear in the left side or right side margin, or in both sides, or inside the text body (on the left of the text) - line numbers may be refered to with \label / \ref - the first line of a numbered program is by default 1, but it is possible to change this first value in two manners: o by specifying a particular first number o by indicating that the next program will start at the line number that follows the last line of the last previous program typed - programs may be globally indented, but a particular occurrence may have a different indentation By default, 7 environments are provided, according to the font size: program normal size programs small size programf footnote size programsc scriptsize programt tiny size programl large size programL Large size For each environment, there exist to file inclusion commands that work in a manner similar to the \verbatimfile and \verbatimlisting commands of the 'verbatimfiles.sty' file: \fprogram? inclusion of unnumbered program \lprogram? inclusion of numbered program where '?' stands for nothing, or for one string in "s", "f", "sc", "t", "l" and "L", according to the font size desired. It is possible to define new environments. For instance \NewProgram{FOO}{LARGE} will define the environment FOO with font size set to LARGE, and to file inclusion commands: \fFOO and \lFOO. Extract the package file from its '.dtx' file as follows: latex programs.ins And get the documented source by: latex programs.drv latex programs.drv latex programs.drv makeindex -s programs.ist programs.idx latex programs.drv ------------ keywords.sty ------------ As a companion to the style programs.sty, here follows a style called keywords.sty whose main purpose is to provide a parameterized way to typeset keywords. This style may be used in conjunction with the programs.sty file, but this is not necessary. What you can do is, for instance, to type a program where keywords will appear boldfaced. It suffices to issue the \ProgKeywords command (global scope), and then to type the text, for instance: \BEGIN \FOR I := 1 \TO 10 \DO .... \ENDDO \END In this example, the keywords are commands defined in the second part of the keywords.sty file. If the environment is such that spaces are obeyed (like in the verbatim environment or by using the programs.sty file), then keywords can be typed as is; otherwise (i.e. in normal text) they must be typed followed by a "\" character (e.g.: \BEGIN\ ...). Assume now, that you want that the program above is typed with keywords written with an emphazised font and underlined, and that words appear in French instead of English. Then take the same program, but just change the "\ProgKeywords" command that precedes it to "\UFAlgoKeywords" (for: Underlined French AlgoKeywords). I have sorted keywords in lexicographic order. If you need to change or add a definition go anywhere among the keywords and type (e.g. definition of the keyword FOO): #1{\FOO}{this is an example}[bla bla]% Then if you chose commands where the 'F' does not appear in the beginning of the name, any occurrence of "\FOO" is replaced by the sentence "this is an example"; otherwise, the sentence "bla bla" will be used. If your wish is that the same expansion is performed for all the commands, the omit tht fourth parameter: #1{\FOO}{this is an example} The commands provided are: ------------------------------------------------------------------------- English keywords French keywords ------------------------------------------------------------------------- \tt BOLDFACE DISPLAY \ProgKeywords \FProgKeywords \tt NORMAL DISPLAY \ttKeywords \FttKeywords \em DISPLAY \AlgoKeywords \FAlgoKeywords underlined \em DISPLAY \UAlgoKeywords \UFAlgoKeywords normal (\rm) DISPLAY \NormalKeywords \FNormalKeywords ------------------------------------------------------------------------- As I am French, I have used English and French languages; however you can use any couple of languages you want. I recall that if parameter 4 in keyword definition is omitted, then only the first language is used. The file terminates by a command that selects the default mode (in the current case this is \UFAlgoKeywords).
