'name': 'Web Widget - Formulas in Float fields',
|
||||
'version': '1.0',
|

'category': 'web',
|
||||
'description': """
|
||||
Allow to write simple mathematic formulas in Integer / Float fields
|
||||
===================================================================
|
||||
|
||||
Functionnalities:
|
||||
------------------
|
||||
* Possibility to tip a text like "=45 + 4/3 - 5 * (2 +1)";
|
||||
* if the formula is correct, The result will be computed and displayed;
|
||||
* if the formula is not correct, the initial text is displayed;
|
||||
|
||||
Documentations:
|
||||
------------------
|
||||
* Video: http://www.youtube.com/watch?v=jQGdD34WYrA&hd=1
|
||||
|
||||
Technical informations:
|
||||
------------------------
|
||||
* Overloads "instance.web.form.FieldFloat"; (so works for fields.integer & fields.float);
|
||||
* To compute, the module simply use the eval() javascript function;
|
||||
* Rounding computation is not done by this module (The module has the same behaviour if the user tips "=1/3" or if he tips "0.33[...]");
|
||||
* avoid code injonction by regexpr test: "=alert('security')" is not valid;
|
||||
|
||||
Limits:
|
||||
--------
|
||||
* Only supports the four operators: "+" "-" "*" "/" and parenthesis;
