fatal: unable to read files to diff

This happens on all repos I have.

I am using Ubuntu 17.10, and have git version 2.14.1.

I think this is because the underlying prettier_d process died, but the ~/.prettier_d file is still present (this happens when you reboot your machine). Try removing ~/.prettier_d and rerunning prettier-diff.

[josephfrazier]

This should be fixed in v0.0.15 (just published)!

[ariselseng]

Great! Thank you:) You were totally right about it being prettier_d file that was present.

[josephfrazier]

Sure thing! I had definitely encountered this problem as well, but just hadn't gotten around to fixing it.

I have the same error with the latest version, could you please confirm?

[josephfrazier]

@sandangel can you run the following and copy/paste the commands and output here:

rm ~/.prettier_d
prettier-diff --version
prettier-diff # put your arguments here

[sandangel]

hi @josephfrazier , there is no prettier-diff --version option.
I do a fresh install with yarn global add prettier-diff

$ yarn global add prettier-diff
yarn global v1.13.0

Ah, this is due to a difference in how nc works on Linux vs macOS. Your best bet is to open the prettier_dnc script (find it with which prettier_dnc) and delete the -q 0 from the nc command options. Let me know how it goes!

I've recently rewritten the prettier_d project (on which prettier-diff depends) and removed the prettier_dnc script, so if I get a chance, I'll likely update prettier-diff as well.

hi @josephfrazier I think prettier-diff is using the latest commit from prettier_d
package.json

"prettier_d": "https://github.com/josephfrazier/prettier_d.js",

let me try editing the prettier_d script

[josephfrazier]

Oh good catch, I had forgotten about that. Yeah I'll probably have to change some things here before it'll work again
