Thanks! I came up with the following:
import parseutils, strutils
proc splitArgs(args: string): seq[string] =
var
parsed, tmp: string
i, quotes: int
while i < args.len:
i += args.parseUntil(parsed, Whitespace, i) + 1
tmp.add(parsed)
if parsed.startsWith('"'):
quotes.inc
if parsed.endsWith('"'):
quotes.dec
elif quotes > 0:
tmp.add(" ")
if quotes == 0:
tmp.removePrefix('"')
tmp.removeSuffix('"')
result.add(tmp)
tmp = ""
if tmp.len > 0:
result.add(tmp[1 .. ^2])
let text = "spam eggs \"spam and eggs\""
doAssert text.splitArgs == @["spam", "eggs", "spam and eggs"]
Run
I chose not to cover single quotes because I don't want to have to handle words
like "don't". Advice on how I could improve on this?
