Add 'string.*' command group

• ✔️ Update / finish documentation
• ✔️ UTF8 support for all this!
• ✔️ string.len → value
• ✔️ string.substr → string
• ✔️ string.strip → string (optional char sequence to strip, lstrip / rstrip?)
• ✔️ string.replace → string
• ✔️ string.map → string
• ✔️ string.split → list
• ✔️ string.join → string – like cat, but with a delimiter
• ✔️ string.contains[_i] → value
• ✔️ string.equals → value
• ✔️ string.endswith → value
• ✔️ string.startswith → value
• ❌ string.chop – see string.substr
• ✔️ string.[lr]pad → string

I create 2 new methods that should work like math.* commands (accepting both string and number but not list), what shall I call the group?
data.* or chars.* or ... ?

• exposing u8_chop : chars.chop (accepts max 3 params)
  • print=(chars.chop, "1234567", 3, 1) -> 12…
• chars.pad (accepts max 4 param)
  • print=(chars.pad, "123", 5, "0", 1) -> 00123

These can be chained together as well:

• print=(chars.pad, (chars.chop, "1234567", 3), 5, "x") -> 123xx

This group suppose to deal with "strings" and do some manipulation on them, but it behaves differently than the string.* group.
They can be used to display something on the UI or during logging (log.execute).

Thanks

Edit: I picked chars.*

Here's the usage examples for the chars.* group, I extended your idea of logging.
Thanks for this as well!

A string is a list of chars, I don't see the need for a new group name. That they implicitly convert values is not enough ‘different’ for me. Things are complicated enough, and adding a stink of PHP doesn't help. ;)

:D :D :D You can rename them in ps, and I will rename it in ch if the setup project will reach 1.0 (I want to do couple of nontrivial things until then). That's why I asked for your opinion back then. It matters for me!
