Something went wrong attempting to parse the PHPCS output.

[Skeeve]

I receive this error even with this most basic file:

<?php

running phpcs on commandline with the same file gives me

$ phpcs Ohne\ Titel

FILE: […]/Ohne Titel
----------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE
----------------------------------------------------------------------
 1 | ERROR | Missing file doc comment
----------------------------------------------------------------------

Time: 59ms; Memory: 4Mb

The Developer Tools do not output anything except for

PHPCS Response            main.js? [sm]:326

[Skeeve]

Seems it's the Joomla standard I use. Running

$ phpcs --standard=Joomla Ohne\ Titel
E

FILE: /Users/shk/Projects/SIWECOS/business-logic-api/Ohne Titel
----------------------------------------------------------------------
FOUND 1 ERROR AFFECTING 1 LINE
----------------------------------------------------------------------
 1 | ERROR | Missing file doc comment
----------------------------------------------------------------------

Time: 97ms; Memory: 4Mb

Gives an additional "E" as first character :( Maybe that's the issue.

After a few tests: It isn't.

[Skeeve]

I've experimented a bit more.

Seems this is the commandline executed by the plugin

phpcs --report=json -q --encoding=UTF-8 --warning-severity=2 --tab-width=4 -s --stdin-path='Ohne Titel' -

My understanding is that phpcs should parse my file from commandline.

Unfortunately executing above command simply hangs on my Mac. Something's really weird here.

Executing

phpcs --report=json -q --encoding=UTF-8 --warning-severity=2 --tab-width=4 -s 'Ohne Titel'

works as expected.

[Skeeve]

More tests revealed that I have to execute:

phpcs --report=json -q --encoding=UTF-8 --warning-severity=2 --tab-width=4 -s --stdin-path='Ohne Titel' - < Ohne\ Titel
{"totals":{"errors":1,"warnings":0,"fixable":0},"files":{"\/Users\/shk\/Projects\/SIWECOS\/business-logic-api\/Ohne Titel":{"errors":1,"warnings":0,"messages":[{"message":"Missing file doc comment","source":"PEAR.Commenting.FileComment.Missing","severity":5,"type":"ERROR","line":1,"column":1,"fixable":false}]}}}

And - as you can see - the result is fine.

Nevertheless linter-phpcs receives receives an empty reply :(

Does no one have a clue what's going wrong here?

I also tried to "ktrace" phpcs while called from atom. I have the feeling it's not started due to a page fault.

First few lines of the trace show:

Final status: Seems somehow my atom installation is borken… Removin ~/.atom and installing linter-phpcs and its dependencies reveals no strange issues at all.
