tstl-simple-inline-func
TypeScriptToLua plugin that performs inline expansion to functions that you annotate.
This plugin is intended to handle functions that do NOT take parameters. If you need to handle parameters, try TSTL-extensions by @Cheatoid instead.
Inline expansion may or may not provide any performance benefit depending on your Lua runtime. Always measure with real world code.
:exclamation: Use this and any code transformation plugin with caution. Mistakes are possible.
Usage
Add a comment containing @inlineStart
before the function you want to inline, and @inlineEnd
directly afterwards.
Example:
/** @inlineStart */
const FOO = () => {
const BAR = 1 + 2 + 3;
};
/** @inlineEnd */
FOO();
Becomes:
-- @inlineStart@inlineEnd
local BAR = 1 + 2 + 3
Subsequent comments
Keep in mind, TSTL may choose to strip comments. If you have multiple inline functions next to each other, you may have to combine comments.
This example may NOT work because the first @inlineEnd
may get stripped:
/** @inlineStart */
const FOO = () => {
...
};
/** @inlineEnd */
/** @inlineStart */
const BAR = () => {
...
};
/** @inlineEnd */
This example may work because we've combined the middle comments:
/** @inlineStart */
const FOO = () => {
...
};
/** @inlineEnd @inlineStart */
const BAR = () => {
...
};
/** @inlineEnd */
Removing return
To strip the return
keyword from your function, add a comment with @removeReturn
somewhere after @inlineStart
.
Example:
/** @inlineStart @removeReturn */
const FOO = () => {
return 7;
};
/** @inlineEnd */
const BAR = FOO();
Becomes:
-- @inlineStart@inlineEnd
local BAR = 7
