Specifying files with spaces in the name to clojure.contrib.command-line

[Kevin Albrecht]

This utility is very useful, but it seems unable to handle passing in
file names with spaces in them.

Example program:

;--------- begin args.clj
(ns args
(:use clojure.contrib.command-line))

(with-command-line *command-line-args*
"args -- test of args"
[filenames]
(doseq [filename filenames]
(prn filename)))
;---------- end args.clj

I run the program like this:
> clj args.clj ~/src/no_spaces.txt "~/file with spaces.txt"

And the results are this:

"/Users/smith/src/no_spaces.txt"
"~/file"
"with"
"spaces.txt"

When they should be this:

"/Users/smith/src/no_spaces.txt"
"~/file with spaces.txt"

P.S. Also, unrelated to this problem, the following line in the
example code in command_line.clj is missing the vector surrounding the
bindings of the doseq:

:else (doseq filename filenames

This works for me. Maybe there's a problem with your "clj" script.

I get this:

$ clj /tmp/args.clj one two "three three three" four
"one"
"two"
"three three three"
"four"

Does this work for you?

(doseq [arg *command-line-args*]
(prn arg))

And this?

(ns args
(:use clojure.contrib.command-line))

(with-command-line ["one" "two two" "three"]

"args -- test of args"
[filenames]
(doseq [filename filenames]
(prn filename)))

My clj script basically does this:

java -server -cp "${CLASSPATH}" clojure.main "${script}" "$@"

The quotes are necessary around the $@, otherwise you will get the
symptoms you are seeing.

That's the old syntax for doseq, so I suspect nobody remembered to
update the example.

Ah, this was the problem, thanks.

Fixed, thanks.
