LDT/User Area/Execution Environment file format
Execution Environment
An Execution Environment, which may also be referred to as EE, is file containing information about the environment on which a lua application will be executed.
So, If you want enable some IDE features (autocompletion, code documentation, ...) for a given execution environment (Lua 5.1, Corona, mihini, Gideros, ...) you can create your own custom EE, there are just a few rules to follow the type of the file and its inner structure.
File format
An EE is simply a regular .zip file.
File structure
To be a valid EE, a ZIP file root must respect the following tree structure.
-
/
-
api.zip
-
docs/
-
index.html
-
-
*.rockspeck
-
api.zip
is a regular ZIP archive containing Lua API files written with the right format.
You could generate this api files from your source code (lua and C) with LuaDocumentor command line tool.(perhaps one day luadocumentor will be able to generate the complete execution environment)
Note: All the globals variable your will defined in global.lua will be considered as preloaded global variables, this means they will be always available in LDT autocompletion.
docs
is a folder containing html
documentation files. index.html
is the file opened by LDT when user ask for EE documentation. (see LuaDocumentor)
*.rockspeck
enable to specify information about an EE, it is strongly inspired by the Rockspeck format. So far, following fields have been added to match LDT needs:
api
documentation
flags
You may have noticed that api.file
is set to 'api.zip'
and documentation.dir
to 'docs'
. Do not change those values in the *.rockspec you write, it will have no effect.
As I am writing, all parameters are hard coded, except:
-
package
-
version
It is temporary, we will soon handle all *.rockspec settings. This why you must write valid *.rockspec to be compliant with up coming versions of LDT.
A sample of EE manifest
package = "lua"
version = "5.1"
flags = { ee = true }
description = {
summary = "Lua 5.1 Execution Environment",
detailed = [[ Lua 5.1 Execution Environment Support]],
licence = "MIT",
homepage= "http://www.lua.org/manual/5.1/manual.html"
}
api = {
file = "api.zip"
}
documentation ={
dir="docs"
}
