in reply to self limiting regex help

If I understand your conditions correctly, this should do:

print if /^ [ACGT]* ([RYMKSWHBVDN])? (?:[ACGT]|\1)*([RYMKSWHBVDN])? (?:[ACGT]|\1|\2)*$ /ix;

    Eureka! I was just attempting to do something similar, but had discovered that \n doesn't work in a character class.

    Thank you (and everyone who responded) very much for your help!

[Discipulus]: anyway once I proposed an automatic font decrease for post below -1, stepping every 5 votes: i'm still thinks it's a good idea but dunno if feasible

[shmem]: Discipulus: has that been in the CB? or in a PM node proper? for the latter case, can you provide the ID?
[Discipulus]: you seriously can use their in this way in eng?
[Corion]: Meh. $effin_bad_system has an interface breakdown and then loads events in parallel with events overtaking one another instead of being processed sequentially
[shmem]: Discipulus: dunno, but we do all the time ^^
