--[[ @file enum_generator.lua
|
|
|
|
This script can be used to generate an enum in game_share.
|
|
Minimal usage:
|
|
require("enum_generator")
|
|
enum_generator.build("name", { "VAL" })
|
|
|
|
Name parameter can be a table of strings, in which case each string will be
|
|
treated as a word and concatenated in various ways. Example:
|
|
enum_generator.build({ "composed", "name" }, { "VAL" })
|
|
|
|
The name of the generated file will be composed_name.h and composed_name.cpp,
|
|
and thus your lua script should be composed_name.lua.
|
|
|
|
Default templates for h and cpp files are respectively in
|
|
enum_generator_template_h.lua and enum_generator_template_cpp.lua. You should
|
|
only modify these templates in a generic way to avoid breaking existing
|
|
generated enums. If you need specific templates you can provide your own to
|
|
the build method. Example:
|
|
enum_generator.build(name, enum, "int %name1%[];", "int %name1%[] = { %enum1% };" )
|
|
