Deno fmt command does not complain about missing files

[srackham]

$ deno fmt non-existant-file.ts
Formatted 0 files in 213ns

$ echo $?
0

$ deno --version
deno 0.32.0
v8 8.1.108
typescript 3.7.2

Is this the expected behaviour?

Maybe we should handle this like the test runner; non-zero exit code if there are no matching files.

[srackham]

@nayeemrmn: That would still allow file name typos to slip through unnoticed e.g.

deno fmt non-existent-file.ts existing-file.ts  # 1 file formatted.

I think a basic solution is simply to warn "No file matching {...}" when we get empty paths after running glob on a pattern

Fixed in #3988 and released in v0.33.0
