Hi, I'm currently trying to adapt my MP specials to the 'new' plugin handler. My actual problem is the splitting of the 'ssh_colors' string with lpeg. Sadly my knowledge about lpeg is nearly zero and it would take me a few days to understand this (my mind is already contaminated with 'regular expressions'). How do I split the 'ssh_colors' string ["ssh_colors"]="1:1:0 0.949:0.729:0 0.894:0.514:0 0.835:0.341:0 0.776:0.216:0 0.706:0.125:0 0.631:0.063:0.588 0.549:0.027:0.953 0.443:0.008:0.953 0.318:0:0.588 0:0:0", to get the single color strings (r:g:b) in say 'col[i]'? Regards, Peter

Hi Peter, there are some examples for „lpeg.splitat“ and „string.split“ on the wiki: http://wiki.contextgarden.net/String_Manipulation#lpeg.splitat.28delimiter.2... Best regards, Philipp

Thanks for the link! The more examples, the better. :-) I have to learn this stuff...
