hello guys,
i want each lines of the output of a shell command to become a key of a
dict. I wote this code:
let t = {}
for k in split( system("echo foo; echo bar "), '\n' )
let t[k] = 1
endfor
but i don't like it: as the loop is here to populate the dictionnary, i
would like to use something more appropriate. In perl for exemple, the
map function enables you to write
my %a = map { $_ => 1 } split /\n/, qx< echo foo; echo bar>
vim has the equivalent of $_: it's called v:val, so i tried to use map
or filter with attempts looking like that:
let t = map( split( system("echo foo; echo bar "), '\n' ), { v:val : 1 } )
and yet i just wonder if it's possible.
regards,
marc
