TagCompiler-1.0

From WowAce Wiki

Documentation is very very initial. More to come.

TagCompiler-1.0 is a library to provide tag based customization to addons. Each addon specifies which tags it handles, and what those tags mean, and TagCompiler generates an efficient function to realise the desired result.

Example

local tagData = { name = { compileString = function() return "UnitName(data)" end } }
local result = TagCompiler:Evaluate("Unit's name: [name]", tagData, "string", "player")
assert(result == "Unit's name: "..UnitName("player"))

API Documentation

 :Compile(tag, tagData, resultType)

Compiles a tag and returns a table containing information about the compile.

Args

tag 

The tag to compile

tagData 

Information about the tags to be handled

resultType 

One of "string", "number", or "raw"

Remarks

Example

 :FixCasing(tag, tagData, resultType)

Cosmetic fixup of the tag to match the casing in tagData

Args

tag 

The tag to compile

tagData 

Information about the tags to be handled

resultType 

One of "string", "number", or "raw"

Returns

string - The tag passed in with cases adjusted to how the casing is specified in tagData.

Remarks

This function is not required for proper operation. Calling it allows formatting of user-entered strings to provide a consistent appearance and increase chances of cache hits between multiple tags within the same addon.

 :HighlightSyntax(tag, tagData, resultType)

Inserts color codes into tag strings for nicer display.

Args

tag 

The tag to compile

tagData 

Information about the tags to be handled

resultType 

One of "string", "number", or "raw"

Returns

string - The tag passed in with colors adjusted

Remarks

If you use this function to color tags for input, make sure you remove the color codes before using the tag.

tag = tag:gsub("|c%x%x%x%x%x%x%x%x", ""):gsub("|r", "")

 :Evaluate(tag, tagData, resultType, tagParameter)

Args

tag 

The tag to compile

tagData 

Information about the tags to be handled

resultType 

One of "string", "number", or "raw"

tagParameter 

Arbitrary user data passed into the tag's handlers. This can be a table, a string, or whatever your handlers are designed to work with.

Returns

The result of evaluating the tag. If resultType is string or number, then those are returned. Raw will return whatever the tag evaluates to, with no type coercion.
