Parsing `--allow-read=...`

[tcely]

I recently reviewed the code for parsing flags. It looks like , isn't allowed in the paths used at all.

Is this accurate?

I would like to know how to allow reading authors/last, first directory or any other path that contains ,.

Thanks.

Have you tried using quotes? Also providing a reproduction code that you have problem with would be helpful.

I included quotes in this reproduction:

$ deno --version
deno 2.6.5 (stable, release, x86_64-unknown-linux-gnu)
v8 14.2.231.17-rusty
typescript 5.9.2

$ deno run --ext=ts --allow-read='authors/last, first' <( echo 'console.log(Deno.readFileSync("authors/last, first/listing.txt"))' )
error: Uncaught (in promise) NotCapable: Requires read access to "authors/last, first/listing.txt", run again with the --allow-read flag
console.log(Deno.readFileSync("authors/last, first/listing.txt"))
                 ^
    at Object.readFileSync (ext:deno_fs/30_fs.js:755:10)
    at file:///dev/fd/63:1:18

$ deno run --ext=ts --allow-read='authors' <( echo 'console.log(Deno.readFileSync("authors/last, first/listing.txt"))' )
Uint8Array(14) [
   72, 101, 108, 108, 111,
   44,  32, 119, 111, 114,
  108, 100,  33,  10
]

I think deno is parsing the first command as --allow-read='authors/last' --allow-read=' first'

[lucacasonato]

In flags taking multiple arguments, you must escape commas with another comma. So --allow-read='authors/last, first' should be --allow-read='authors/last,, first'.
