I was playing with this piece of code to print a list of chars:
perl -e 'print join(" ", map { sprintf "%02x", ord } grep /\s/, map { chr } 0x0 .. 0x7F )'
Is there a easier way to write map { chr } 0x0 .. 0x7F
?
I've tried:
map \&chr 0x0 .. 0x7F
But I get syntax error.
map { chr } 0x00 .. 0x7F
is already pretty concise, but in addition to the map BLOCK LIST
syntax, there is also the map EXPR,LIST
syntax.
map chr,0x00..0x7f
map chr,0..127
