Lua function
lpeg.C
Summary
Creates a simple capture
Prototype
lpeg.C (patt)
Description
Creates a simple capture, which captures the substring of the subject that matches patt. The captured value is a string. If patt has other captures, their values are returned after this one.
For example:
digits = lpeg.R ("09")
hp = lpeg.P ("You gain ") * lpeg.C (digits^1) * " hp."
print (lpeg.match (hp, "You gain 300 hp.")) --> 300
