Deno permissions flags required to use ddc after updating deno/installing for the first time

[lukelbd]

Problems summary

The latest version of deno (1.29.2) requires the following --allow flags for ddc.vim to work after updating deno or installing deno for the first time (I installed deno with mamba install deno):

let g:denops#server#deno_args = ['--allow-env', '--allow-net', '--allow-read', '--allow-write']

Perhaps this is specific to the deno version I installed. But if not, it might be a good idea to add some notice to the documentation / at the top of your readme. Or, you could even include these flags by default when ddc starts the server?

Expected

The ddc plugin works like normal / without errors on startup.

Actual

The ddc plugin throws many many different errors without the above init.vim setting.

Provide a minimal init.vim/vimrc without plugin managers (Required!)

" Your minimal init.vim/vimrc
set runtimepath+=~/path/to/ddc.vim/
call ddc#enable()
" Uncomment to fix the errors:
" let g:denops#server#deno_args = ['--allow-env', '--allow-net', '--allow-read', '--allow-write']

How to reproduce the problem from neovim/Vim startup (Required!)

Simply start vim with ddc enabled and the versions listed above.

Upload the log messages by :redir and :message (if errored)

• Without the flags, after installing / updating deno, deno emits many many error messages indicating that the above flags are required.
• With the flags, when starting vim for the first time, deno emits messages indicating that different components are being downloaded / installed.
• After this step, when starting vim again, the above g:denops#server#deno_args setting is no longer required for ddc to work like normal.

I can no longer get the specific error messages, but hopefully you can still reproduce. Thanks for the great package.

Please use the latest version of deno. Because 1.29.2 is not the latest.
