import { matchstr } from "https://deno.land/x/denops_std@v6.4.0/function/mod.ts";
Same as match(), but return the matched string. Example:
:echo matchstr("testing", "ing")
results in "ing".
When there is no match "" is returned.
The {start}, if given, has the same meaning as for match().
:echo matchstr("testing", "ing", 2)
results in "ing".
:echo matchstr("testing", "ing", 5)
result is "".
When {expr} is a List then the matching item is returned.
The type isn't changed, it's not necessarily a String.
Can also be used as a method:
GetText()->matchstr('word')
