emacs-tree-sitter has issues with auto-yasnippet: wrong-type-argument char-or-string-p nil

[shackra]

After creating a snippet, when I expand the snippet in a Python buffer, I got this error:

Debugger entered--Lisp error: (wrong-type-argument char-or-string-p nil)
  tree-sitter--after-change(2045 2151 106)
  run-hook-with-args(tree-sitter--after-change 2045 2151 106)
  #f(compiled-function () #<bytecode 0x446903a9>)()
  funcall(#f(compiled-function () #<bytecode 0x446903a9>))
  (let nil (funcall (quote #f(compiled-function () #<bytecode 0x446903a9>))))
  eval((let nil (funcall (quote #f(compiled-function () #<bytecode 0x446903a9>)))))
  yas--snippet-create("if data.$1:\n            feed = team_pb2.UpdateTeamInput.$1.DESCRIPTOR.name\n            mask.paths.append(feed)" nil 2045 2045)
  yas-expand-snippet("if data.$1:\n            feed = team_pb2.UpdateTeamInput.$1.DESCRIPTOR.name\n            mask.paths.append(feed)")
  aya-expand()
  funcall-interactively(aya-expand)
  call-interactively(aya-expand nil nil)
  command-execute(aya-expand)

the result is that the string is expanded, but those parts with $1 are empty.

My Emacs version: GNU Emacs 26.3 (build 1, x86_64-apple-darwin18.2.0, NS appkit-1671.20 Version 10.14.3 (Build 18D109)) of 2019-09-02

This seems to be one of the edge cases in Emacs's change tracking mechanism, where the to-be-changed range passed to before-change-functions is empty, but the before-change-text's length passed to after-change-functions is non-zero (106).

Can you provide more details to reproduce/debug it? For example:

• The Python file.
• The snippet being used (and maybe yasnippet's config).
• Steps to trigger the behavior. For example, any navigation/editing after opening the file.

I can't lend the python file due to it being part of a commercial software project, instead I will try to reproduce on the same machine with a minimal example, just give me a couple of hours. El vie., 10 de jul. de 2020 a la(s) 08:52, Tuấn-Anh Nguyễn ( notifications@github.com) escribió:

I ran a session of debugging with elisp bug hunter and this is the results:

You have asked to do an interactive hunt, here's how it goes.
1) I will start a new Emacs instance, which opens a new frame.
2) You will try to reproduce your problem on the new frame.
3) When you’re done, close that frame.
4) I will ask you if you managed to reproduce the problem.
5) We will repeat steps up to 11 times, so hang tight!
Doing some initial tests...
Initial tests done. Hunting for the cause...

confusing to say at least lol.

I cannot reproduce this bug on my GNU/Linux machine running Emacs 28 tho. I will try to reproduce with a minimal conf and see what happens

Cannot reproduce on my GNU/Linux machine with Emacs 26. Maybe this is isolated to macOS somehow

I just reproduced this bug on my GNU/Linux machine:

indeed, @ubolonton, I'm having troubles narrowing what is causing this issue in my configuration.

I was able to reproduce 10/10 times the error with the following snippet:

(with-current-buffer (find-file-noselect "/tmp/test/main.go") ;; file must exist and be empty
  (company-complete-selection))

I have deleted a bunch of unused packages in my configuration https://github.com/shackra/emacs

[shackra]

I've updated some packages on my end:

• company-mode/company-mode@4462e7d
• joaotavora/yasnippet@5cbdbf0
• sebastiencs/company-box@39e3671
• radian-software/prescient.el@cc289ba
• with 527badc installed.

and seems like the issue is gone now. I'll re-open this issue if happens again.

these are the commits I have for some of those packages before updating shackra/emacs@6ad8e87
