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

inspect(lpeg.match(lpeg.tsplitat(" "),ssh_colors))

Hi Peter, there are some examples for „lpeg.splitat“ and
„string.split“ on the wiki:

Best regards, Philipp
