| No matter what i do in a Lua script, i cant get a pattern to include an OR.
solo = "http://ggg.cnn.com http://www.cnn.com www.cnn.com monkey-tribble-duck w.cnn.com w ww oog.nomface.com www wwww w|www wW W WW WWW ouote o.ote.com.nom ___ gggg quote q.ote.com.nom.con WWWW WWW. http://www.cnn.com"
luke = "([hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/])|([wW]+[wW]+[wW]+[\.])"
leia = "[hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/]|[wW]+[wW]+[wW]+[\.]"
r2d2 = "(([hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/])|([wW]+[wW]+[wW]+[\.]))"
c3p0 = "([hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/])*([wW]+[wW]+[wW]+[\.])*([hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/])"
jaba = "(([hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/])*([wW]+[wW]+[wW]+[\.])*([hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/]))"
boba = "[hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/]*[wW]+[wW]+[wW]+[\.]*[hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/]"
yoda = string.find(solo, luke) -- fails
yoda = string.find(solo, leia) -- fails
yoda = string.find(solo, r2d2) -- fails
yoda = string.find(solo, c3p0) -- fails
yoda = string.find(solo, jaba) -- fails
yoda = string.find(solo, boba) -- fails
I'm out of options here X_X;
There is no way to put an OR into the pattern of a string.find is there?

| Lua pattern matching isn't the same as PCRE. The rex library has all the pcre syntax you're looking for.
The simple answer to your question is "No. Use 'or' between 2 string.find calls" :)
yoda = string.find(solo, "[hHtTpPsSmMaAiIlLoO]+://[%S]*[%w#/]")
or string.find(solo, "www") or string.find(solo, "WWW")
Lua Pattern matching doesn't support an | as "OR", or {}s for repetition quantifiers (i.e. %w{2,3} doesn't match at least 2 but no more than 3 alpha chars.)
Lua patterns tend to run a bit faster, since they're more simplistic. The speed of the language generally matches or exceeds the speed of compiling a rex regexp.
function IsUrl (darth)
local vader = darth:lower()
if vader:find("^http://") or vader:find("^mailto://")
or vader:find("^www") then
return true
end
end
That should accomplish what you're looking for. | | Top |
