Development languages (.lng) are rewritable files, which fill text to insert.
Data are organized in a tree with two levels. (Screenshot)

• .lng file is formated like standard windows .ini file:
  To create a node, write text between []: [Sample]
  To add an item to this node, add its name to new line
  followed by '=' and a value between 1 and 4
  1=>Collection/Table 2=>Property 3=>Methode/Function 4=>Event
  sample:
  stringtoadd=3
  To add contextual help to an item
  add | (pipe) and your text:
  stringtoadd=3|This is contextual help of item
  See .lng files shipped with HAPedit as samples. (Php, Asp, VBScript, ADODB and CSS).
• Depending on the terminology of the language, the text to insert can be table/collection, property/constante/var, method/function, event.
• The Languages window may be displayed by pressing Crtl+D.
• To add, edit or configure language options, see in Menu: Options | Development languages:
  Each language has its own parameters for insertion text and you can rewrite them depending your needs. (right-click)

Remark: Hints of items are in French only. See 'Help Context' parameter to deactivate it.
