NS_ERROR_UNEXPECTED with custom linter

How To
1

I’ve created a linter for Komodo (https://github.com/Defman21/korubocop, I’m planing to integrate it in Komodo). However, I’m not able to get it working.

Here’s the error in my log when I open a ruby file:

[2017-01-30 20:27:41,954] [ERROR] lint:

I can access the linter itself with Cc["@addons.defman.me/koRubocopLinter;2"] so at least I’m sure Komodo loads it, but I don’t understand the error. Is it an issue in my code?

/cc @mitchell, I’d appreciate your help since you have the knowledge of linters :slight_smile:

@Defman please add debug logs to your linter python file and add try/catch statements. This isn’t something we can help with as we cannot possibly know what type of error your code is triggering.

3

I added a lot of try catch statements and logs, but I don’t see them at all :confused:

See what koLintService is doing:

require("ko/logging").getLogger("koLintService").setLevel(10)

The uid does not match the one in my linter though. Could it be a conflict with the default Ruby Komodo linter?

Have you managed to disable the default Ruby linter? Sorry, but that error traceback is not making much sense to me :frowning:

7

I’ve disabled it by changing _reg_categories in KoRubyCompileLinter class and it does not any linting anymore, but I still get the same error.

8

I see. Sorry, but I don’t have any time to try and help debug this right now. I’m not very familiar with adding new linters either, so I cannot offer any advice off the top of my head. If I think of anything I will let you know. I wish you luck.

I’ve fixed my problems by compiling the linter as built-in Komodo linter. It gave me errors related to encoding in my code and I’ve fixed them. Thank you for the help @mitchell and @nathanr
