restore buffers after git_reset_branch function

[xnorly]

After undoing commits with telescope's git_reset_branch function, the buffers do not reload and still show the old state. Therefore I added a restore_buffers function in actions/utils.lua, that does exactly that:

• reloading all the buffers with vim.cmd("bufdo e")
• turn syntax on again with vim.cmd("syntax on") (because bufdo may turn off syntax to increase speed)
• show previously shown buffer with vim.cmd("b" .. currentBuff) (because with multiple buffers opened, bufdo will change the view and not return back to the previously shown buffer)

The restore_buffers function could also be used in other git functions. Which is why I added it to the utils module.

Interesting fix. I have auto-read enabled so when the file on disk changes the buffer gets updated but this seems to be better way to avoid some errors, in particular, I'm interested to know what will happen in the following cases:

• buffers open but not saved yet.
• buffers open but no longer exists after a git command

Additionally, what other function do u think we should have this in.

Thanks for the detailed explanation

Hi tami5
Thanks for your answer.

I have no clue yet about how to treat the situations you mentioned.

Here are other functions that (I think) could make usage of the restore_buffer function:
git_switch_branch
git_apply_stash
git_checkout
git_merge_branch
git_rebase_branch
git_reset_branch

I tried set autoread in vimrc, but it didn't work as expected:
After git_switch_branch, the buffer still showed old branch state. Only after clicking outside the terminal window and clicking back into it, the buffer showed the new state. Maybe it's a setting of my terminal?

best regards

Any update ?
