Module:Ustring/doc

This module directly imports all functions from the mw.ustring library.

The module takes an indefinite number of arguments. All arguments are coerced as number type if possible. If you wish for something to remain a string, you can escape it with \, which in turn can be escaped by itself.

You can also wrap results in tags. All non-number indexed arguments will be passed to { frame:extensionTag

Usage

{{#invoke:Ustring|function_name|arg1|arg2|...}} is equivalent to mw.ustring.function_name( arg1, arg2, ... )

Example using mw.ustring.sub

{{#invoke:Ustring|sub|abcde|2|4}}

produces:

bcd

Example using mw.ustring.gsub

{{#invoke:Ustring|match|abcde|(c%w)}}

produces:

cd




Example using tag arguments

{{#invoke:Ustring|sub|{{Module:Ustring}}|274|548
|tag=pre|style=background-color:#edd}}

produces:

			local str_i = 1
			while fargs['s' .. str_i] do
				fargsused['s' .. str_i] = true
				args[str_i] = fargs['s' .. str_i]
				str_i = str_i + 1
			end
			for i, v in ipairs(fargs) do
				fargsused[i] = true
				args[i + str_i - 1] = tonumber(v) or v:gsub("^\\", "", 1)
			

Note that:

<pre style=background-color:#edd>{{#invoke:Ustring|sub|{{Module:Ustring}}|274|548}}</pre>

produces:

{{#invoke:Ustring|sub|{{Module:Ustring}}|274|548}}
