Add `read --tokenize` This splits a string into variables according to the shell's tokenization rules, considering quoting, escaping etc. This runs an automatic `unescape` on the string so it's presented like it would be passed to the command. E.g. printf '%s\n' a\ b returns the tokens printf %s\n a b It might be useful to add another mode "--tokenize-raw" that doesn't do that, but this seems to be the more useful of the two.

read: discard IFS delimiters before the last token Do this only when splitting on IFS characters which usually contains whitespace characters --- read --delimiter is unchanged; it still consumes no more than one delimiter per variable. This seems better, because it allows arbitrary delimiters in the last field. Fixes #6406 2019-12-20 02:32:18 +08:00
Run fish_indent on all our fish scripts It's now good enough to do so. We don't allow grid-alignment: ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` becomes ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` It's just more trouble than it is worth. The one part I'd change: We align and/or'd parts of an if-condition with the in-block code: ```fish if true and false dosomething end ``` becomes ```fish if true and false dosomething end ``` but it's not used terribly much and if we ever fix it we can just reindent. 2020-01-14 03:34:22 +08:00			`echo "a b b" \| read a b`
