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.
!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.)
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'.
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 fullpower 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.
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 want 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.
http://wims.unice.fr/wims/wims.cgi
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:
Parameter string  Meaning 

cmd=intro  get introduction page of the module 
cmd=new  open new working session 
cmd=renew  restart working session 
cmd=reply  send reply to the module 
cmd=next  get next exercise (in a working session) 
cmd=config  set preferences 
cmd=help  get contextual help 
cmd=hint  get contextual hint 
cmd=resume  resume work (e.g. after help) 
cmd=getins  get dynamic insertions: internal use by the server. Not to be used by modules. 
http://wims.unice.fr/~wims/wims.cgi?cmd=new&+module=tool/algebra/factor.encalls the wims server at wims.unice.fr, with `new' as the value of `cmd', `tool/algebra/factor.en' as the module name.
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 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.
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 nonescaped newline characters. A newline 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: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 nonspace 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.
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:
3*$(alpha$(i)beta)*xwill become
3*pi*xafter substitution.
Array addressing: if the variable l contains a commaseparated list a,b,c,d,e, then the string $(i[3]) gives c after substitution, and $(i[2 to 4]) tives b,c,d, etc.
Twodimensional array addressing is also available: if
$M=x,y,z;a,b,c(a 2x3 matrix), then
$(M[1;3,2])=z,y
$(a$[$i1])*x+$(a$[$i2])will become
pi*x+3after substitution.

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). 
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.

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).
The syntax for a range of integers is n1 to n2. For example, 2 to 2 means the whole string except the first and the last characters.
If your module depends on datamodules to run, declare them in the INDEX file, then use this command to check the presence of the datamodules. If the answer is "no", you can take actions to lock further access to your module and/or show error messages.
The syntax for a range of integers is n1 to n2. For example, 2 to 2 means the whole string except the first and the last columns.
When vname contains several names, the values of each will be returned with the same separators as for the names.
For example, if type is words, then the first (resp. second, etc.) variable in namelist will be set to the first (resp. second, etc.) word of string.
The curly braces in string can be nested, but the execution runs from outmost pair to innermost pair.
Available opword:
Special case: if the file name starts with getfile/, the file is written to the getfile subdirectory of the session. This file is then accessible via the command
!href cmd=getfile&special_parm=fname_without_getfile_prefixor a complete url
$wims_ref_name?session=$session&+cmd=getfile&+special_parm=fname_without_getfile_prefix
!fileexists themes/standard/_procs/tt.phtmlor for a trusted module,
!fileexists wimshome/log/classes/2001/Exindex
Special case: if the file name starts with getfile, the file is written to the getfile subdirectory of the session. This file is then accessible via the command
!href cmd=getfile&special_parm=fname_without_getfile_prefix, or a complete url
$wims_ref_name?session=$session&+cmd=getfile&+special_parm=fname_without_getfile_prefix
!breakwithin the for loop breaks it. continue is not yet implemented in this version.
The target of the form can be controlled by the variable wims_ref_target. It can also be defined via an optional word target=.... Note that in this case the target must start with wims_.
The variable wims_form_method which must be either get or post controls the method of the form. This method defaults to post for tool modules, and to get for all other modules.
It returns the defined value in the string, or the name itself if it appears in string but if there is no = sign following it, or an empty string if name does not appear in string as a word.
value can be a multiword string, if it is enclosed by a pair of parentheses, brackets, curly braces or double quotes. The enclosing parentheses etc. will be removed from the output.
Spaces are allowed before and/or after the = sign.
parm is reserved for future implementation.
In particular, the result can be used as part of a variable name whatever the content of string is (as long as it is not too long).
The target of the reference can be controlled via the variable wims_ref_target. It can also be defined via an optional word target=.... Note that in this case the target must start with wims_.

islineof  string1 islineof string2  true if string1 is a line of the list string2. 
notlineof  string1 notlineof string2  true if string1 is NOT a line of the list string2. 
issamecase  string1 issamecase string2  true if string1 and string2 are the same text by a comparison insensitive to multiple spaces but casesensitive. 
notsamecase  string1 notsamecase string2  true if string1 and string2 are NOT the same text by a comparison nsensitive to multiple spaces but casesensitive. 
issametext  string1 issametext string2  true if string1 and string2 are the same text by a comparison insensitive to cases, multiple spaces and accented letters. 
notsametext  string1 notsametext string2  true if string1 and string2 are NOT the same text by a comparison insensitive to cases, multiple spaces and accented letters. 
The syntax for a range of integers is n1 to n2. For example, 2 to 2 means the whole string except the first and the last items.
The computation is made from (x1,y1) to (x2,y2), and points are computed as integer positions in a picture with size xsize,ysize.
Order of the fields is not important. All the fields except levels are mandatory.
The syntax for a range of integers is n1 to n2. For example, 2 to 2 means the whole string except the first and the last lines.
!listfile $module_dir
fname may be either in the module directory (in this case the module directory need not be specified), or in the directory bases.
The first word of the first line in the parameter should be the email address.
The rest of the first line is the recepient name (default to email address).
The second line and up is the mail subject.
This command calls, in the order of priority, one of the following files:
In the second syntax, the substitutions are done with respect to each item in the list v1,v2,....
The variable v should appear in templ as a math variable (that is, with no preceeding character).
For example, the command
!makelist [x;x+1;xx] for x in a,x and y,1,(2,3)gives the result
!makelist [x;x+1;xx] for x in a,x and y,1,(2,3)
Actually wims use Wikipedia as the standard reference encyclopedia.
In the second syntax, the values are given with respect to each item in the list v1,v2,....
The syntax for a range of integers is n1 to n2. For example, 2 to 2 means the whole fname except the first and the last records.
In the second syntax, the values are given with respect to each item in the list v1,v2,....
The function fn should use the variable last to indicate the value of the previous recursion step. And the starting value can be put into the WIMS variable $recursion_start.
Browsers translate & primitives into corresponding (special) characters even when these primitives occur in input or textarea fields. Also, if string contains html tags, they may confuse browsers. You can use this command on the string (usually derived from an earlier user input) before inserting them back into a input or textarea, to avoid the above problems.
This command is useful with exercises where important information is carried by multimedia files (pictures, audios, movies). It can be used to hide the name of the multimedia file that otherwise would give clues to the solution of the problem.
The renamed file must be located within the module, and the filename f should start with $module_dir.
The command returns a string which is the new URL. The file is not effectively copied or renamed on the server.
Under the first syntax, variable substitution is first done on string.
Then all occurences of substring s1 are replaced by s2.
When the keyword internal is absent, the Linux utility sed is called to make the replacements,
therefore regular expressions are accepted in s1 and s2.
Please refer to the man page of sed for details.
Under the second syntax, obj can be char, word, item or line.
Then the word, item or line identified by ident in string is replaced
by s, after variable substitutions.
ident can be a string, in this case all objects (words, items or lines) matching ident
will be replaced. It can also be a number (positive or negative integer n), preceded
by the word number. In this case the object number n will be replaced.
(In the case where n<0, it is the last n th object which is replaced.)
This command can be only used before output starts. Repeated restart is disabled, to avoid infinite loops.
The condition can use words column 1, column 2, etc. to designate commaseparated columns in each row.
fn may have several roots in the interval [v1,v2], but roots too close to each other may be overlooked.
In the second syntax, the values are given with respect to each item in the list v1,v2,....
parm is reserved for future implementation.
In the second syntax, the values are given with respect to each item in the list v1,v2,....
fns may be a commaseparated list of functions.
This command can also be used to make recursions. If the functions fns contain a variable named last, this variable will take the value of the last step each time. And the starting value can be put into the WIMS variable $recursion_start.
If the switch nofn is present, function names will not be listed.
The syntax is the same as for if.
The syntax for a range of integers is n1 to n2. For example, 2 to 2 means the whole string except the first and the last words.
The symbol names are based on corresponding TeX names.

It uses its own programming language designed for symbolic as well as arbitraryprecision 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 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 modulespecific 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. dprompt good answer prompt given under doubleunderlined variable (internal reply__$i) ; in this mode, the good answer is not present by default. nogood never present good answer (because there cannot be). noanswer never present the answer analysis (because there is no good or bad answer) These scripts accept the following input variables. i The number of the reply field. replyname$i The prompt of the form element. reply$i The answer given by the student. replygood$i The good 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 $i" if the good answer given by the author is not understandable. test Put "NaN" followed possibly by an error indicator, if the answer given by the student is not understandable. diareply$i Diagnostics result. Possible values: "good", "bad". precreply$i If the answer misses the good result just by a problem of precision, put "yes" to this variable and put "bad" to diareply$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$i If the answer should be considered as partially good, put "yes" to this variable and put "good" to diareply$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 good 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 et 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$i This variable can be defined for the good answer shown to the students after replying to the exercise, if it should be different than the real replygood$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_$i m_sc_reply$i by default 0, 0.5 or 1 according to diareply$i, partialgood$i and partialgood$i. Can be set to special values. Give the possibility to the developer of exercises to give feedbacks without testing again. There are also some variables which can be used (new/2009) oef_formnosubmit: if yes, no "Send answer" button appear. oef_js_submit: can be used to put javascript in the answer button, the line onclick="javascript:$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$i indexed on the numero of the answer.) If you use an external software, use the variable ans_require (best if there is a version number). Add the help in scripts/help/anstype and scripts/help/anstype.$lang and in the list help/$lang/reply.phtml
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 concate 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 créezle 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, faitesle dans un fichier lang/home_names.xx . Si les définitions sont faites dans un module administratif, par exemple dans modules/adm/class/exam/lang/names.phtml.xx, faitesle dans un fichier de nom adm_class_exam_lang_names.phtml.xx  il est possible d'utiliser les "widgets" du répertoire themes/_widgets A 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)
