ASCII

strutils: proc toLowerAscii(c: char): char
strutils: proc toLowerAscii(s: string): string

(1) ASCII
print('a'.upper()) # A print('A'.lower()) # a print("adam".upper()) # ADAM print("LASZLO".lower()) # laszlo	import std/strutils # strip, split, join echo 'a'.toUpperAscii() # A echo 'A'.toLowerAscii() # a echo "adam".toUpperAscii() # ADAM echo "LASZLO".toLowerAscii() # laszlo

𝥶In Python, 'a' is equivalent to "a". When you write 'a' in Python, it's actually a 1-long string.

If you have Unicode characters, then use the std/unicode module.

unicode: proc toLower(c: Rune): Rune
unicode: proc toLower(s: string): string

(2) Unicode
print('á'.upper()) # Á print('É'.lower()) # é print("ádám".upper()) # ÁDÁM print("LÁSZLÓ".lower()) # lászló	import std/unicode # Rune echo "á".toUpper() # Á echo "É".toLower() # é echo "ádám".toUpper() # ÁDÁM echo "LÁSZLÓ".toLower() # lászló let c: Rune = "á".runeAt(0) d: Rune = "É".runeAt(0) echo c.toUpper() # Á echo d.toLower() # é

𝥶Python cheats a bit. In Python, there is no distinct char type. When you create a "char", it's actually a 1-long string.
