It seems to be a problem with a single letter.

For example if I use "mm", it works:

$ crystal init app mm
    create  mm/.gitignore
    create  mm/.editorconfig
    create  mm/LICENSE
    create  mm/README.md
    create  mm/.travis.yml
    create  mm/shard.yml
    create  mm/src/mm.cr
    create  mm/spec/spec_helper.cr
    create  mm/spec/mm_spec.cr
Initialized empty Git ...

It's bug in file.cr method #dirname.
This code:

full_path = "m/.gitignore"
puts "Full path: #{full_path} dir name: #{File.dirname(full_path)}"

prints:

Full path: m/.gitignore dir name: .

I will look at it.

What Crystal version? Because I remember a similar bug and it should be already fixed in master (and maybe in 0.31.1, not sure)

[asterite]

Oh, nevermind, I just tried it and it's broken in 0.31.1

@asterite I guess you are thinking of #8119
