[REGEX] How to capture any color text value on the fly ?

02 Sep 2019, 15:33

Hello,
In this example RGB value " 777,0,0 " witch is not a valid RGB value is also captured. How to avoid this? :think:
If i remove the first 3 letters from the variable, value " 800000 " is not captured why ?

Code: Select all

var=
(
try
800000	777,0,0 kldjfdoifj 12,12,3 dfjiosjf jksdi
8000AA	128,0,0 125,125,125|255,254,253 0xffaabb
FF0000	256,0,0
FFA500	257,165,0
FFFF00	550,255,0

800080	128,0,128

FFFFFF	255,255,255
)

colors:=[]
p:=0

while p:=RegExMatch(var, "[0-9a-fA-F]{6}|(\d{1,3}) ?, ?(\d{1,3}) ?, ?(\d{1,3})", color%a_index%,  p+strlen("color" %a_index%)) 
{
colors.push(color%a_index%)
}

msgbox, % st_printarr(colors)


; (by tidbit)
st_printArr(array, depth=5, indentLevel="")
{
   for k,v in Array
   {
      list.= indentLevel "[" k "]"
      if (IsObject(v) && depth>1)
         list.="`n" st_printArr(v, depth-1, indentLevel . "    ")
      Else
         list.=" => " v
      list.="`n"
   }
   return rtrim(list)
}

This is not capturing any of the valid RGB trio of values like 257,165,0. He's not looking to capture only the hex values, he also wants the trios of decimal values but only if they're valid (0-255) which 777,0,0 isn't.

it matches any 6 hexchars in a row and any comma separated triplets, then stores only the hexchars and valid triplets. 257 and 777 arent stored

A pure regex-solution to match your 0...255 triples - it uses a more specialized regex than your simple \d{1-3}

Yes, the script does that. :!: Like me, you are probably using an older version of AHK. Replace !Vars.Count() by !Vars.maxindex() to fix the problem.

Thanks, could you make it so it also match 255,0,000 or 12,00,07 format ?

swagfag code is the closest to what I'm looking for. I forgot to mention it, the StrLen() jumping feature should only applies to R,G,B format and not to hex #RGB format. I modified swagfag code to make it more tolerant regarding hex RGB value so that for a string like "backgroundFFAAFF" , "dFFAAF" and "FFAAFF" values will be both captured.

I still have a major problem. :(
Why is the first value " 80FF80 " not captured in this new example ? :think:

Code: Select all

		colors.push(m)
}

03 Sep 2019, 05:48

I think that neither backgroundFFAAFF nor any of the substrings of 0123456789ABCDEF is actually a RGB color value, so it makes no sense for me. But

Code: Select all

pos := 0 ; changed from 1
m := ""
while (pos := RegExMatch(clipboard, "[[:xdigit:]]{6}|(\d{1,3}) ?, ?(\d{1,3}) ?, ?(\d{1,3})", m, (instr(m,",")) ? pos + StrLen(m) : pos+1))
{
should do what you want (the first match will be searched at position 1, not 2).

It could be shortened:

re_255 := "\b(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\b"

The tool I created will display any selected value. Suppose you want to know what "456789" looks like in string "0123456789ABCDEF" is it red, blue or green? I'm a lazy person and instead of selecting the exact value with a mouse drag I'll just double click to select the entire word press a keyboard shortcut and immediately see that the value 456789 is blue. That's why the script must be very permissive. (Same for "backgroundFFAAFF") ;)

For sure ... https://regex101.com/r/iJ3fUc/1:

The regex has to be:

Code: Select all

re_255  := "\b([0-1]{0,1}[0-9]{0,1}[0-9]|2[0-4][0-9]|25[0-5])\b"
As teadrinker mentioned, this expression could be shortened by replacing [0-9] with \d ....

Code: Select all

re_255  := "\b([0-1]{0,1}\d{0,1}\d|2[0-4]\d|25[0-5])\b"
