[TF] Request for function.

[mazur at xs4all.nl (S. Linnemann)]

Hello, once more,

I have some variables, set from world input, that contain colour codes
as well as the value I seek.  Now i'm trying to program a function to
strip the colour codes from the variable, and leave only the rest.
Alas my programming skills seem to desert me on this, all I achieve is
either an infinite loop or the value 1.

Setting the emulation to ansi_strip is no solution, because much more
than the three values I capture are coloured, adn that helps
tremendously in recognising what to look for in play.  It's only these
few values, that need their colours stripped.

The problem is as follows:
	there are one or two colour codes sequences at the start in the
variable, there may be a colour code sequence at the end.
	Solution: 
Step 1: Find escape character, if found, find first letter "m" after
that, call the position of this "m": i.
Step 2: From position after "i", search next escape char.  If this is
not the following character, the wanted value lies between.  If no
eacape character is found, the wanted value is from i+1 to end of
string.
--  There ar no other escape sequences in the string, only those colour
codes sequences.
-- So far the only colour code sequences are invariably of the form
\033[..m, with two cyphers at the dots.  Two colour codes at the start
means twice this sequence.

I should be able to program this myself, but I seem to misunderstand
several basic characteristics of Tinyfugue.

Your help would be enormously appreciated.

Stefan.
