greetings

i'd like to pad a string... say for instance i want to pad the string "andy" and "ian" to be able to have a total of 10 characters, and the padding character will be an underscore. so the end result would add 6 underscores to the string "andy" and seven underscores to the string "ian": "andy______" "ian_______"

i poked around through extended and did a search on the list archives for "character pad" and "string pad", nothing came up in the archives, and the only things i found in extended are mrpeach's [str] help examples, and moocow's [string2any], [any2string] help examples. it looks like mrpeach's stuff is the closest to what i want, but i don't think it's what i want. after tofofmtl introduced me to pdmtl, i expected there would be some string handling in to coincide with the list stuff they have too, but nothing there.

thanks, andy

moin Andy,

This is quite easy using [string2any] and [any2string] together with pd's [list] operations. see attached example patch. I'm sure the same basic idea can be used to pad [str] strings as well...

Is it the best method ? I'm not sure. Is it what you are looking for ? ++

wow, thank you :)

I've never used [s2l], [list-len], [Uzi], [last-x], [Append], or [prepend set] ..... lots of new goodies to look at!

thanks alot, this looks like exactly what i wanted. i will now meditate on the patch for some time.

You may need to find some external that will give you the length of a symbol. Then substract that from your desired total length, make a list of that length with your symbol and use [list-l2s] from list-abs to build a single symbol out of your original string and the padding.

Or just install pdlua and use attached lua-external. Once you've install pdlua, you can do all kinds of string/symbol processing using Lua's string library easily.
