What is WIMS?

WIMS (Www Interactive Multipurpose Server) is an internet server system designed for mathematical and other educational purposes.

The Wims server is composed of a kernel program which is a cgi program (wims.cgi), plus various activity units called ``modules''.

The client browser accesses the server via a http request to wims.cgi, with parameters specifying the name of the module to request, the type of the request, and possibly parameters for the module ; wims.cgi processes the requested module, passing the user parameters to it, and sends the result returned by the module back to the client.

A module may consist of a number of script files grouped in one directory. These scripts are written in a special scripting language: the WIMS language.

The WIMS language contains commands which allow it to call external programs (especially various mathematical softwares) to make sophisticated computations. Such commands are processed by wims.cgi and sent through interface programs which filter the request, check for security breaches, and send back a filtered output.

Examples of what you can do with WIMS

The current version 4.21f of wims has several applications which demonstrates (non-exhaustively) what one can do with a wims system.

Comparison with other approaches

Advantage of wims versus locally installed softwares

  1. No need of software installation and/or update by users.

    All installation and/or update of background software is done on the server side, which can be anywhere on the internet. On the client machine, only a common web browser is required (which needs not to be very up to date).
  2. No need to learn the usage and the syntax of a particular software package.

    As wims uses the html standard for user interface, a user, in particular a student, has only to use his usual knowledge of html browsing (which is now a common knowledge), in order to work on wims applications.
    This is not the case for any of current mathematics softwares; all of them require a training period before the user can work on it. This training period may be more or less lengthy, but we remark that the knowledge of using a particular software is not a universal knowledge, and such a knowledge usually has a short lifespan. Moreover, teaching knowledge about a commercial software contradicts with the principle of commercial neutrality of a public education institution.
  3. It provides a means to collect the knowledge and experience of the whole educational community.

    Wims is a modular system, where each application is a separated module whose links with other modules are done in the usual html way. This allows modules to be developped independently and remotely. It is our hope that as many educators as possible will add their knowledge and experience to the system by contributions in the form of new modules or improvements of existing ones.
  4. It allows student - teacher interactions in several ways.

    Organized under the structure of classes, a wims system allows teacher to assign works for his students, and get reliable informations about the progress (and/or difficulty) of the student in real time. This may allow the teacher to give more personalised guide to the student. The big advantage of such a system based on internet is that there is no site restriction: any work done from any site (local or remote) is valid, and is taken into account.
  5. It provides a dynamic interaction between different components, e.g. between exercises and computing tools.

    For example, practically no software dedicated to exercises can interface a computational tool as easily as wims does.
  6. It can be more powerful than any given software for certain works.

    Because wims can use different (dedicated) software as backend engine, even several softwares for one application or one request.

Disadvantage of wims versus locally installed softwares

  1. Low speed of reaction.

    Because usually every wims response has to travel through internet. This will improve when internet speed improves.
  2. Limited computational power and programming capability.

    If a user has a heavy computational job and/or has to design a complicated script to get his job done, he should work directly on the appropriate software. It is not at all the intention of wims to interface such activities.
  3. Limited capability of the graphical interface.

    The html graphical user interface is not very suited for interactive works.

Advantage of wims versus hand calculators

  1. Easier to use.

    A html page used by wims for user interface is much more comprehensible than any hand calculator.
  2. (Much) more powerful.

Disadvantage of wims versus hand calculators

  1. Non-portability.

    Wims is accessible only to computers connected to internet.

Advantage of wims versus interactive web applications based only on java or javascript

  1. More powerful and more versatile.

    As wims can embed java or javascript programs in its applications, a wisely designed wims application just extends the capability of java or javascript.
    And wims can really do more: even if it is theoretically possible to develop java applications which has the same power as a software used as a backend engine for wims, it would take too much effort to develop (is it reasonable to re-write TeX in java?), and would be so big that it would take forever for an http query to load.
  2. Easier to develop.

    Because wims language is first based on html (easy to learn), with an extension specifically designed for this purpose.
  3. Allows student-supervisor interaction.

    The design of server-based interactivity for users allows the back-end communication with supervisors, and much more (performance analysis, automatic intervention from supervisors, etc).

Disadvantage of wims versus interactive web applications based on java or javascript

  1. Lower speed of reaction.

    Because usually every wims response has to travel through internet. This will improve when internet speed improves. One can also use embedded javascript or java in a wims application, in places where response speed is important.

Current features of WIMS

  1. Write html pages with a programmability extension: substitution of variables, conditional branching, etc.

    This wims programmability extension to html does not require any addon or plugin at the browser side, as all the wims commands are treated by the wims server before sending the result to the browser, which will be a standard html page.
    For example, this allows you to define style macros which can be dynamically changed.
    And this extension can cohabit with all the current (and hopefully future) html standards, including java applets, javascripts, embedded objects, dhtml... This is because the wims extension follows a strict line discipline (i.e. a wims command must start at the first word of a line), while html standard is not line-oriented.
    This means that you can even embed wims extensions into javascripts, applets, dhtml...
  2. Dynamic insertions of paints, plots and TeX formatted mathematical formulas into html pages.

    For example, you may insert the following line into your wims-extended html page. At the browser side, the visitor will see a TeX formatted matrix whose content varies with the value of the variable $matrix:
          !instex $$ \left( $matrix \right) $$
    Moreover, this implementation of dynamic insertions makes future updates possible without modification at module's level. (For example when a better way to render mathematical formula is available, a simple modification at server's level will immediately let all !instex lines take benefit of the new standard.)
  3. Insplot is now animated!

    Exemple: the tool Tracés Animés .
  4. Direct interfaces to powerful external software packages.

    For example, you may define a variable `factor' by the following line:
          factor=!exec pari print(factor($number))
    Upon execution of this line, the variable will be replaced by its current value, then the software package `PARI' will be called with the string `print(factor(<value of $number>))' as command to execute. The output of the program, with the overheads stripped, will be placed as the value of the variable `factor'.
    Interfaces provided in version 4.21f of wims: PARI, Maxima, MuPAD, Coq, Povray, gnuplot, PostgreSQL, Fly (gif drawing), CALC (by Keith Matthew).
  5. Simple and versatile language.

    The language used for wims modules is an extension of the existing and popular html language. This extension is designed to be simple, easy to use and close to natural language. Synonymes are accepted whenever necessary. For example, to include the content of another file, you don't have to remember whether the command is include as in C, or input as in TeX, because both are valid.
  6. Convenient directives for string manipulations:

    replace with regular expression capability, extraction of a subset from a list of items, shuffle, evaluation of mathematical expressions, etc.
  7. Easy inline mathematical symbols:

    simply type $m_pi for pi, $m_RR for RR, $m_le for le, $m_Rightarrow for Rightarrow, etc.
  8. Intelligent treatment of mathematical expressions:

    built-in translation routines to allow error-tolerant expressions like 2y (instead of 2*y) or (x+1)(x-1) (instead of (x+1)*(x-1)), and translations of raw mathematical expressions into beautified html sources (x^3-3*x^2+1*x-5 will become x3-3x2+x-5 , etc.), or TeX sources, etc.
  9. Powerful random capabilities:

    random permutation (shuffle), random record from a datafile, random filename, etc.

Online development of activities

The system includes several facilities allowing you to create and develop WIMS activities directly online. To do so, you have only to click on the respective links from the home page of the server.

The easiest is the creation of simple interactive exercises which does not really require the knowledge about a computer language, but exercises that can be written in this way have limited power and versatility.

On the other hand, you can also develop full-power WIMS modules by working entirely on line. For obvious security reasons, you will need a login/password pair which you must ask the site manager to attribute to you. Once logged in, you can create and modify as many modules as you like, in a special development zone. When you have finished the development of a module, you can ask the site manager to move it to a public place.

Basic structure of WIMS

The central piece of a wims server is a cgi program, usually in the name of wims.cgi. It takes all the http calls to the server, then does the following work:
  1. Call the module asked by the user, and process parameters and variables according to what is defined in the module.
  2. Session management.
  3. Send the result of the process to the user.
  4. Write to different log files.

Modules of wims

A wims server is a modular system, with different applications as modules. At each new call to wims, the user has to specify which module he wants to access.

A wims module may be an interactive course or interactive exercise (of any level), a computational tool, a dictionary, a mathematical game, a database, or a mixture of the above.

Wims modules are independent from each other. Each module has its own directory, which serves as its address, and contains all the files of this module. Different modules have different authors and different maintainers, and may follow different copyright policies.

There is no relation between modules in a same wims site, except hypertext links which allows one module to access another in various ways.

How to access a wims server

Wims is accessed by a request to the main cgi program, for example

which usually should be followed by parameters. A call to the main wims.cgi program without parameter will bring up the wims homepage of the site.

Parameters of wims.cgi is a usual http name=value pair, where the name field may be one of the following:

calls the wims server at wims.univ-cotedazur.fr, with `new' as the value of `cmd', `tool/algebra/factor.en' as the module name.

How to use the supervisor-side interface

Supervisors of registered classes can maintain their classes and consult results of students via the same web address (the main cgi program), just by logging in as supervisor. All the options are then available via html links and buttons.

Table of Contents

Structure of a WIMS module

Each wims module has a private home directory in which go all the files of this module.

A module must have at least the following files:

And it may often contain the following (optional) files too:

There may be any number of other files, like a README.md file, one or more help pages, an about page, one or more graphics files, files called by one of the above mandatory or optional files, etc.

Variable processing files

The files var.init and var.proc, as well as any files called by these two files, are variable processing files.

A variable processing file is divided into lines, separated by non-escaped new-line characters. A new-line character can be escaped by the character \, in which case it does not separate the two lines before and after it.

Every line of a variable processing file must be one of the following:
  1. A comment line, whose first non-space character is either the character #, or ! followed by another !.
  2. A variable definition line, in the form of name=value. The content of value may be a string (if this string contains a new-line character, it must be escaped by the character \), or a wims variable command (which must then start with the character !).
  3. A command line, whose first non-space character is the character !, followed by the command name and optional parameters.
    If the command produces an output string, this output will be ignored.
  4. A label line, whose first non-space character is the character :, followed by the name of the label. Anything following the label name will be considered as comment and ignored by the interpreter.
    Label is used in conjunction with the jumping command !goto.
    A label starting with the character '*' is catch-all, matching any !goto label.
  5. Any line not fitting into one of the above 4 will generate a wims error message.

Phtml files

The files main.phtml and intro.phtml, as well as any files called by these two files, are phtml files (programmable html).

A phtml file is an ordinary html file, except for lines whose first non-space character is a ! or a :.

Lines can be escaped by \, just as in the case of a variable processing file.

A line starting with : is a label line, as in the case of a variable processing file.

A line starting with ! is a command line, as in the case of a variable processing file. To the difference that if the command produces an output string, this output will be inserted into the html page, at the place of the line.

Lines not of the above two types will be sent to the http client, after substitution of variables.

Table of Contents

Variables in a module

Definition and substitution of variables

Wims variables have only one type: they are all string variables. Numerical evaluation can be done on variables via the variable command !eval.

A variable may be defined or modified in a variable processing file, or by the commands !let and !default.

Variable names can contain any alphanumeric character, as well as the underscore character _. There is a limit to the length of variable names, and a limit to the length of values. (Limits depending on server configuration.)

Variable substitution can be done anywhere in a variable processing file or a phtml file (even in the name field of a variable definition line). A word preceeded by the character $ is considered to be a variable name, and will be replaced by its value when the line containing it is processed.

Special rules of variable substitution:

Reserved variable names

The following names are reserved for their special meanings. They should not be used for internal needs of any module.

Table of Contents

Variables with special meanings

Variables for general purposes by wims server
wims_exec_error is used to store error messages of the external program called by !exec. For this reason, this variable will be overwritten each time a !exec command is executed.
wims_module_log is used for individual module's log files: if this variable is non-empty, wims.cgi will put its content into the module's log file, at the end of the process of the user request.
wims_version has a value preset to the current version of the wims server.
wims_version_date has a value preset to the last compile date of the server program.
wims_site_manager contains the electronic address of the site manager, as defined in the configuration file wims.conf of the site. Modules should not modify this variable.
wims_print_precision defines the printing precision when a result of evaluation (via !eval or NaN) is converted to a character string. Default value: 8 (may be modified in wims.conf).
wims_warn_ ... is ...
wims_compare_precision is used to define error tolerance when wims compares two numerical values. Formula: !ifval a=b will return TRUE if


Default value: 10000 (may be modified in wims.conf).
wims_texsize can be used to modify TeX sizes for the module. Default value is 0 (no change). Maybe 1,2,... (increase TeX size) or -1,-2... (decrease TeX size).
wims_homeref_parm is reserved for future use in the command !homeref.
wims_homeref_bgcolor is...
wims_rawmath_functions is used to tell rawmath routine that the words contained in the variable value should be treated as function names. These words can be separated either by white space or by comma.
wims_rawmath_variables is used to tell rawmath routine that the words contained in the variable value should be treated as math variable names. These words can be separated either by white space or by comma.
wims_ref_name gives the addess of the wims serveur (for this server, https://wims.u-psud.fr/wims/wims.cgi)
httpd_HTTP_HOST gives the name of the wims serveur (for this server, wims.u-psud.fr)
wims_protocol gives protocol used (http, https. for this connexion )
wims_ref_target defines the target of the command !href, !homeref, !form. Its value is not automatically reset to empty after the commands. (Defaults to empty string, meaning that the target is the current document.)
wims_ref_id defines the id in the command !href (<a ... id=" ">) and in the commands !formradio, !formcheckbox and !getfile. Its value is automatically reset to empty after the commands. (Defaults to empty string)
wims_ref_class defines the css class in the command !href (<a ... class=" ">) and in the commands !formradio, !formcheckbox and !getfile. Its value is automatically reset to empty after the command. (Defaults to empty string)
wims_ref_title defines the title in the commands !href and !getfile (<a ... title=" ">). Its value is automatically reset to empty after the command. (Defaults to empty string)
wims_html_mode can be used before a command as !formradio, !formcheckbox. It forces the results of the formradio to be inside the html mode. The value must be span, li, div. It could be td.
wims_getfile_fname can be used before the command !getfile to specify the value for the download attribute, which will be the new filename of the downloaded file.
wims_html_header is the standardised html header for all its modules' html outputs. Its value is defined in the file html/header.phtml. It is highly recommended that modules use this variable to define their html headers.
wims_expire is used to define expiration dates of the pages sent to clients. Don't touch it if you don't know what this means.
module_init_parm is...
wims_ins_alt if the value is empty, no automatic alt is inserted (should be put in ins_attribut for example); if the value is none, alt="" is inserted.
jquery_defined if the value is yes, one can use jquery script (some themes do not use it, so another solution must be found even if there is less functionnality as dragdrop).
freepar_ If a variable begins by this prefix, no check on parenthesis is done.

Variables reserved for dynamic insertions
ins_align defines the manner in which the inline picture is aligned with respect to the line. Possible values: bottom, middle or top. Default is empty (which means bottom).
ins_attr is used to define miscallaneous attributes of a dynamic insertion. Examples:
  ins_attr = align=middle
(aligns the middle of the image with the baseline for the current textline), or
  ins_attr = ismap
(coordinates of the click will be passed back to the server; if the link of the element is the wims server, the coordinates will be registered under the variable no_name.)
This variable is reset to empty after a dynamic insertion.
ins_border is used to define border width of the html element IMG resulted from the dynamic insertion. Its value should be a positive number.
This variable is reset to empty after a dynamic insertion.
ins_density is used to define the density of the dynamic insertions. Default value: 100x100 .
Avoid using this variable! We are planning to suppress it. Will be replaced by a server-managed variable.
ins_format can be used to determine the format of the graphics file of the dynamic insertion: its value should be either gif or jpg. The default value of this variable is gif (which can be changed by modifying the file wims.conf; but such change is not recommended).
Some types of dynamic insertions may not be affected by this variable.
ins_quality is used to define quality of the graphics convertion used in dynamic insertions. Its value should be between 0 and 100. Affects only dynamic insertions whose graphics format is jpg.
ins_tag is used for dynamic insertions within a form. In this case define
ins_tag=form name where name is the name of the html element IMG within the form (optional).
This variable is reset to empty after a dynamic insertion.
insdraw_size is the size in pixels for the dynamic insertion. ins_filename is the name of the graphics file of the dynamic insertion (generated by wims). It must be taken just after the command !insdraw
ins_url is the url of the graphics file of the dynamic insertion. It must be taken just after the command !insdraw
insplot_data is ...
insplot_font is ...
insplot_set is ...
insplot_split is ...
insplot_transparent is used to define transparent color for insertions. Default is empty (no transparency). Usual value: 255,255,255(white is transparent).

Variables reserved for software
wims_backslash_insmath if the value is yes, it is possible to use the notation \( \) to insert mathematical expressions.
force_mathml if the value is yes, force mathml output of tex formulas.
disable_mathml If the value is 1, disable mathml output of tex formulas. The variable disable_mathml has priority on force_mathml.
pari_precision give the pari precision of the computation with Pari/GP
print_precision give the precision of the computed number at the end of the computation.
maxima_precision give the maxima precision of the computation with Maxima.
wims_multiexec If the value is yes, allow the multiexecution of the mathematical software
use_comma If value is 1 moneyprint will use a decimal comma. Any other value or no value will use the decimal point notation. Only to be used for presentation purposes.

Data structure


There is no special syntax in wims language for arrays. However, it is possible to design array-like variable structures, with integer or even string subscripts. This can be done using nested variable substitutions. For example, ...

Fields in a string

Wims variables are all string variables. There are three different ways to split a string into fields:

List of commands

WIMS commands can be used in variable processing files and phtml files. A command is a word preceeded by the character !.

Commands has two types:

Some commands can be used both as execution command and as variable command.

Commands may accept parameters which are words following it. Parameter fields are separated by white spaces or special words (depending on the command).

Here is the list of all commands.

Interfaces to external software packages

This documentation is yet not finished ... WIMS provides interfaces for some software packages which must be installed independantly.
the PARI group
Use PARI/GP est un système de calcul formel très répandu, conçu pour des calculs rapides en arithmétique (factorisations, théorie algébrique des nombres, courbes elliptiques...) mais contient aussi un grand nombre de fonctions pour le calcul matriciel, sur les développements limités, les nombres algébriques, etc. ainsi que de nombreuses fonctions transcendantes.

Use Maxima is a system for the manipulation of symbolic and numerical expressions, including differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors. Maxima yields high precision numeric results by using exact fractions, arbitrary precision integers, and variable precision floating point numbers.

Use Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. Automatic graph drawing has many important applications in software engineering, database and web design, networking, and in visual interfaces for many other domains.

The GAP Group
Use GAP is a system for computational discrete algebra, with particular emphasis on Computational Group Theory. GAP provides a programming language, a library of thousands of functions implementing algebraic algorithms written in the GAP language as well as large data libraries of algebraic objects. See also the overview and the description of the mathematical capabilities. GAP is used in research and teaching for studying groups and their representations, rings, vector spaces, algebras, combinatorial structures, and more.

Use interface to bc ; bc -l

Use YACAS is an easy to use, general purpose Computer Algebra System, a program for symbolic manipulation of mathematical expressions. It uses its own programming language designed for symbolic as well as arbitrary-precision numerical computations. The system has a library of scripts that implement many of the symbolic algebra operations; new algorithms can be easily added to the library. YACAS comes with extensive documentation (hundreds of pages) covering the scripting language, the functionality that is already implemented in the system, and the algorithms we used.

How to do an anstype

# How to add a new anstype (called here `_name`) Each anstype contains two files, `_name.input` is the input form element, and `_name` is the answer processing file. Specific anstypes need not be put into this directory. One can create a subdirectory "anstype" in the module, then put the files there. Any name will do, but we recommend that module-specific anstypes use a specific prefix for its names, like "mynumeric", "myfunction", ..., in order to avoid possible confusions. In an oef exercise, the anstype is called by the line `\answer{xxx}{yyy}{type=_name}{option=zzz}` see later for the intern variables corresponding to the values. The input file should contain the following two definitions: 1. define `anstype=yes`. Otherwise the OEF manager will not recognize the existence of the anstype. 2. define the form style using the variable `anstyle`. Here are the possible words to declare in this variable: * `mc`: multiple choice style. * `symtext`: allows symtext processing. * `numeric`: the data is numeric or with an input field * `dprompt`: correct answer prompt given under double-underlined variable (internal `reply__$i`); in this mode, the correct answer is not present by default. * `nogood`: never present correct answer (because there cannot be). * `noanswer`: never present the answer analysis (because there is no correct or wrong answer) These scripts accept the following input variables: * `i`: The number of the reply field. * `replyname$i`: The prompt of the form element. * `reply$i`: The answer given by the student. * `replygood$i`: The correct answer given by the author. so the value of the second field of `\answer{}{}`. * `replyoption$i`: Option words. Anstypes are more or less free to define their own recognized option words. In oef exercises, it correspond to the value `zzz` in `{option=zzz}` * `inputsize`: the second item of the field \embed{} (the first one is * `r$i` ou `reply$i`). In general, it contains the size of the form element. Moreover, if no comparison is wanted, the answer processing file can have a calling parameter "nocompare" (not useful in oef exercices). Output variables of the answer processing file: * `Test`: Put `bad $i` if the correct answer given by the author is not understandable. * `test`: Put `NaN` followed possibly by an error indicator, if the answer given by the student is not understandable. some available error indicators: * `badsize` (following by a number) * `badform` * `badform noreduced` * `nocompute` * `nocomputecomplex` * `notunit` * `bad_variable` * `unknownword` followed by some words * `chemdraw_empty_data` * `chemclick_empty_data` * `diareply$i`: Diagnostics result. Possible values: `good`, `bad`. * `precreply$i`: If the answer misses the correct result just by a problem of precision, put `yes` to this variable and put `bad` to `diareply$i`. In the computation of the score, a coefficient depending on the level is introduced. In thise case, one must not advance `freegot` at all. * `partialgood$i`: If the answer should be considered as partially correct, put `yes` to this variable and put `good` to `diareply$i`. It has no consequence on the calculation of the real score (use `freegot` for that). * `freegot`: This is a numerical variable. Its content is incremented by 1 if the answer is 100% OK, none if it is false, or anything between 0 and 1 for partially correct answer. It is not recommended to decrement this value, nor to increment it more than 1. The real score is computed using it. So, `partialgood$i=yes + diareply$i=good + freegot` advances of a number strictly between 0 and 1 or `!advance precgood + diareply$i=bad + fregot=0 + precreply$i=yes` There are also some optional output variables (they can be left empty). * `replyGood$i`: This variable can be defined for the correct answer shown to the students after replying to the exercise, It should be different than the real `replygood$i`. It is not shown in the analysis of the answer for false student answer if dprompt is declared in anstyle. * `m_reply$i`: This variable can be defined for the answer shown back in the oef variable `reply$i`, if it should be different than the real answer typed in. * `reply_$i`: The answer of the student shown in the html page in place of `\embed{}` or in the analysis zone (for oef exercises). * `reply__$i`: A special prompt in the analysis of the answer to show when `dprompt` is declared in anstyle. If it is empty, its value is the value of `reply_$i`. If the variable `noshow$i` is yes, the student reply is not shown in the answer analysis. * `m_sc_reply$i`: by default 0, 0.5 or 1 according to `diareply$i`, `partialgood$i` and `freegot`. Can be set to special values. Give the possibility to the developer of exercises to give feedbacks without testing again. There are also some variables which can be used (new/2009) * `oef_formnosubmit`: if `yes`, no "Send answer" button appear. * `oef_js_submit`: can be used to put javascript in the answer button, the line `onclick="javascript:$oef_js_submit;"` will be present in this button (in test). * `oef_anstype_css`: style css (what is inside ``) will be include at the end of the web page. If the following variables are defined in the file `_name.input`, they can be reused in the file `_name`: `oef_applet_option`,`oef_applet_command`,`oef_fill_option`,`oef_answer_option1`..., (for reuse applet options or embed options for example, if one wants to use the anstype several times in the same html page, it is recommanded to use `oef_answer_option$i` indexed by the answer's number). If you use an external software, use the variable `ans_require` (best if there is a version number). Add the help in `scripts/help/anstype` and `scripts/help/anstype.$lang` and in the list `help/$lang/reply.phtml`.
See the lists of the anstype in the OEF documentation even if they can be used in any pedagogical modules (with adaptation of the syntax).

Structure of sub directories

# To add a theme:

1. Decide on the name of the theme. If the theme is not intended for
   publication, please put it under the subdirectory "local":
   `local/1`, `local/YourName`, etc.

   Say the name is `local/1`.

2. Copy the content of `public_html/themes/standard` to
   `public_html/themes/local/1`, and modify.

- un fichier css global est créé par le script mkcss.pl dans themes.
   Ce script concatene et minimise les fichiers css dont la liste est dans le fichier `css.css.template` (respecter la syntaxe ...).
   Vous pouvez ainsi utiliser des fichiers css communs dans `themes/_css` des fichiers d'autres thèmes (à manier avec précaution) ou dans le répertoire `local/1/_css` de votre thème.

- Si vous désirez garder certains fichiers sans changement,
  il est conseillé de faire plutôt un changement de fichiers.
  Par exemple, si vous désirez conserver sans modification le fichier supervisor.phtml
   créez-le en écrivant simplement par exemple
  `!changeto themes/standard/supervisor.phtml`

- Le fichier `local.phtml.template` une fois changé en `local_phtml.fr`
   permet d'inclure des modules administratifs locaux dans les menus

- vous pouvez changer le "vocabulaire" dans la version de langue xx
  (par exemple xx=fr) de la manière suivante :
  créez un répertoire lang.
  Si vous désirez changer la définition des noms
  définis dans html, faites-le dans un fichier
  Si les définitions sont faites dans un module administratif,
  par exemple dans `modules/adm/class/exam/lang/names.phtml.xx`, faites-le dans un fichier de nom

- il est possible d'utiliser les "widgets" du répertoire `themes/_widgets`

  widget front.phtml:
  `!read themes/_widgets/frontmsg.phtml local/data/news.fr blocnews blocexamples`
  argument: `nom_du_module` `nom_du_bloc_news` `nom_du_bloc_exemple`
    (le module doit être dans `local/data`)
  css nécessaires (à rajouter dans `css.css.template`)
  `_css/news.css _css/foundation_button.css _css/foundation_animation.css`

À faire :

- nettoyer un peu plus les fichiers pour n'avoir qu'une succession
de widgets.
- bientôt un appel du type
  `!read themes/_widgets/visitormenubox.phtml`
  lira s'il existe `themes/local/1/_widgets/visitormenubox.phtml` dans `themes/local/1/_widgets` et sinon dans `themes/_widgets`.

* wims_homeref_n0 = renouveler, aide, wims_menu_items (liens venant des modules)
* wims_homeref_n1 : lien sur feuille, séquence, aide, about, resume, divers ! print
* wims_homeref_n2 :
* wims_homeref_n3 : était prévu pour des tabs, ne contient rien à supprimer
* wims_homeref_n4 : contrôle des scores par l'élève
* wims_homeref_n5 contient pour l'instant uniquement l'aide feedback des exos
* wims_hm : lien du menu supérieur (headmenu)

Help for script library

# Model for an slib
The first part (before :proc) is for the documentation.

You can also put the documentation part (everything except slib_author)
in multiple files, one per lang in scripts/help/lang/slib/...
if you want it to be translated.

!if $wims_read_parm!=slib_header
  !goto proc

slib_author=Firstname, Lastname
default, explanation\
default, explanation\
default, explanation


slib_out= result of the slib
slib_comment= more explanation


!distribute items $wims_read_parm into slib_xx, slib_yy, slib_zz, and so on





The result must be in the variable slib_out.

Please prefix all the variables names by slib_.
