The Wims server is composed of a kernel program which is a cgi program (wims.cgi), plus various activity units called ``modules''.
The client 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 eventually parameters for the module. Upon request, 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 recognizable by wims.cgi.
The script language contains also 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 filters the request, checks for security breaches, and sends 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.cgiwhich 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_warn_  ... is ... 
wims_compare_precision  is used to define error tolerance
when wims compares two numerical values. Formula: !ifval a=b will

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_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... 
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 servermanaged 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

This section is not yet finished. Sorry.
Commands has two types:
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.
The output is separated by commas if only one column is selected, or separated in the same way as the matrix string otherwise.
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
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_.

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
Only trusted modules can use this command.
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
[a;a+1;xx],[x and y;x and y+1;xx],[1;1+1;xx],[(2,3);(2,3)+1;xx]
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,....
A datafile is a plain text file whose content is split into a number of records. Records are separated by tag strings "\n:" (a newline character immediately followed by `:'). Lines before the first tag string are treated as comments.
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 is only available to trusted modules, and 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.
defstr maybe multiple line, each being a definition string.
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.
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.

Example 
voronoi  
Steve J. Fortune  
Use  compute Voronoi diagram or Delaunay triangulation. Voronoi reads the standard input for a set of points in the plane and writes either the Voronoi diagram or the Delaunay triangulation to the standard output. 
Input data  Each input line should consist of two real numbers, separated by white space. 
Output data 
If option t is present, the Delaunay triangulation is produced. Each output line is a triple i j k which are the indices of the three points in a Delaunay triangle. Points are numbered starting at 0. If this option is not present, the Voronoi diagram is produced. There are four output record types. s a b indicates that an input point at coordinates l a b c indicates a line with equation ax + by = c. v a b indicates a vertex at a b. e l v1 v2 indicates a Voronoi segment which is a subsegment of line number l; with endpoints numbered v1 and v2. If v1 or v2 is 1, the line extends to infinity.
