[dap-go] Debug extension has changed its file structure

[shackra]

It seems that the extension has changed:

internal/modules/cjs/loader.js:979
  throw err;
  ^

This is the file tree upon deleting ~/.emacs.d/.extension and letting lsp-go and friends make its contents:

I have a copy in one machine which has 0.14.4 as its version, compared to 0.16.1 on my work machine, lsp-go is currently compatible with the former but not with the latter.

[shackra]

yes, not sure what I can do on my own, the files in dist/ do not work due to missing dependencies:

internal/modules/cjs/loader.js:979

[yyoncho]

Can you verify this: #326?

[shackra]

fyi:

@yyoncho got this from Go debug stderr:

(node:27901) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

Process Go Debug stderr finished

I have node v13.11.0

also, in Warnings I got the following:

Warning (emacs): Initialize request failed: unrecognized request

I've attached some logs, but it short: no luck.

[shackra]

any updates with this? is there more debugging information or tests I can do in order to resolve this bug?

[Gleek]

It would be great if we would could update the version manually in dap-go.el to fetch 0.15.0 instead of the latest being fetched right now. This can be moved back to the latest version once we fix the bugs @shackra pointed out with the new version.

[yyoncho]

@Gleek you can path dap-utils-get-vscode-extension - it has version parameter. Also, you can download and extract the extension from marketplace manually in .emacs.d/.extension/vscode/

[Gleek]

@yyoncho I did that already and it works for me. I was suggesting we add this to dap-go.el as well so that things work out of the box for people trying out dap-mode with go.

[yyoncho]

@Gleek thank you, good idea, I will try to do that tomorrow my time.

[yyoncho]

FTR I pushed a change which forces 15.0 version which should work.

[h3poteto]

The master branch works fine.

[shackra]

for some reason I was unable to make it work, but testing now things go smooth and I can debug again

unless there is something else to do this issue can be close

[shackra]

or rather, open the issue again if there is something else
