I updated the IntellisenseCreator files again, fixing the client crash and reworking few things.
The headers can be generated by either
1) compiling create_intellisense.fos by using ASCompiler with -server, -client and -mapper switches, or
2) compiling it as a server, client or a mapper module by either server (for server and client headers) or mapper.
In case of 2), the create_intellisense module should be the last one on the list of modules, in each of server, client and mapper sections.
The advantage of 2) is that the header will be more complete: in addition to API registered by the core fonline applications, it will also contain information about other classes, functions, methods or properties registered by scripts or user dlls (with bindfunc pragma, for instance). Some projects can make an extensive use of this, and IntellisenseCreator is able to generate project-specific files this way.
For information, when it's write "// Arguments for this function have been guessed" it's because AngelScript function return prototype without arguments name?
Yes, and after getting the API information from the AngelScript engine, IntellisenseCreator opens the executable that loaded it and attempts to find within it the strings matching the definitions of the global functions and methods. These strings, being the original ones used to register the API, usually contain argument names.
However, some of the functions did not have the arguments named in the first place (notably certain AS addons), and user-registered functions won't be present in the executable at all. Meaning that few functions won't have their arguments named.
