Weird error: "expecting is not a supported rule" #60

Open darkvertex opened 2 years ago

darkvertex commented 2 years ago

Describe the bug A clear and concise description of what the bug is.

To Reproduce Steps to reproduce the behavior:

  1. Ensure autosave is ON, make a new Dockerfile.
  2. Start typing this: 
    FROM node:latest
WORKDIR

    (Note: WORKDIR has a space after it.)

  3. A notification should appear: hadolint: expecting is not a supported rule

Expected behaviour Okay, so an empty "WORKDIR" is nonsense, but I would not expect the hadolint extension to be worrying about it, let alone throwing a cryptic notification.

Screenshots or Dockerfile

FROM node:latest
WORKDIR

(Note: WORKDIR has a space after it.) image ...and if I pop open the Help->Developer Tools window, I got this in the JS Console: image

Environment and version (please complete the following information):

Debug information I tried running the same command that the extension output log said it was running:

> hadolint C:\Users\alan\repos\redacted\buggy.Dockerfile --no-color
C:\Users\alan\repos\redacted\buggy.Dockerfile:2:9 expecting the workdir path

From my naive understanding, it appears like maybe the extension is expecting rule-style (DLXXXXX....) output strings all the time and not handling those few error messages that don't have a rule to them.

Additional context This issue looks related to #46 and #55.

I should perhaps add that (I think due to #42) even after closing the buggy file, hadolint continues to haunt my notification corner over the file it can't parse right.

I have kind of the same error: image

I had the same error as @bendem - any plans to fix it? @michaellzc
