Question on opening the quickfixlist to show errors from a gcc compilation process about overseer.nvim HOT 5 CLOSED

There is a PR #4 in the works. Meanwhile you can check out this custom component that I created based on (but independent of) this PR that does the same. It is a lua table, but you can just convert that to json and put it in your task.json file

from overseer.nvim.

As Ranjith said, that PR should address this and is in-progress but not finalized. There are some API changes I'd like to make to it before merging. It's been pending for a while because I've had a whole lot going on at work and outside of work, and requests on my open source projects have piled up. Just this last week I've started making headway on the backlog, but I'm out of time again for today. I hope to be able to come back and finish this one up no later than the end of next weekend.

@krishnakumarg1984 after taking another look, your ask is actually independent of that PR. The issue was much simpler: the necessary problemMatcher wasn't included (because it was in the vscode-cpptools extension).

If you get the most recent master and change your tasks.json to have this line: "problemMatcher": "$gcc", that's all that's required to parse the output into diagnostics.

If you then make sure that you have the on_result_diagnostics_quickfix component (with open = true to auto-open quickfix), that should be all you need. This could look like:

require("overseer").setup({
  component_aliases = {
    default = {
      -- These are the default components listed in the README
      -- You probably want to keep them
      "on_output_summarize",
      "on_exit_set_status",
      "on_complete_notify",
      "on_complete_dispose",
      -- This puts the parsed results into the quickfix
      { "on_result_diagnostics_quickfix", open = true },
      -- This puts the parsed results into neovim's diagnostics
      "on_result_diagnostics",
    },
  },
})

@ranjithshegde and @stevearc Thank you for your responses, and thank you for trying to address this request.

I updated the overseer setup call to use the above suggested table, and updated the problemMatcher line in tasks.json to use $gcc, and even after updating to the latest commit of overseer, I still am not able to make this work. i.e. the quickfix window does not open. In fact, the quickfix window seems to not even contain diagnostics. After :OverSeerRun and :OverSeerToggle!, I am getting some garbled characters in the overseer split. Please see the screenshot below which hopefully illustrates these problems.

• The problematic source code in the top right split
• Manually opened (with :copen) empty quickfix window in bottom right
• Overseer window (with :OverSeerToggle!) in the left split

Some questions:

• In your initial tasks.json file, you used the key "problemMatchers" instead of "problemMatcher". Have you corrected that?
• If you expand the task all the way in the overseer list (default bound to L), do you see a "problem_matcher: " line underneath the vscode.result_vscode_task component?
  
• What does the full output of the command look like if you open the terminal?
