모듈:Ustring

This module directly imports all functions from the mw.ustring library. Documentation for each function can be found there.

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

1 Usage

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

lua

Copy

( arg1, arg2, ... )

1.1 Example using mw.ustring.sub

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

produces:

bcd

1.2 Example using mw.ustring.gsub

{{#invoke:Ustring|gsub|1234|23|}}

produces:

14

1.3 Example using mw.ustring.match

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

produces:

cd

1.4 Example using tag arguments

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

produces:

		if frame.args.tag then
			local tag = {name = frame.args.tag, content = mw.ustring[k](unpack(args)), args = {}}
			for x, y in pairs(frame.args) do
				if type(x)~='number' and x~='tag' and not tag[x] then tag.args[x] = y end
			end
			return frame:extensionTag(tag)
		end

Note that:

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

produces:

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