Persist pins through sessions

[otavioschwanck]

Would be nice to have it on barbar.

Does #363 fit the use case? Or is there something different you had in mind?

i think it fits!

@Iron-E i upgraded and the buffer pin is still not being persisted!

[Iron-E]

Did you :doautocmd User SessionSavePre, then :mksession foo.vim (or any other session management command) before exiting? Then to load, nvim -S foo.vim

Im using persistence.nvim. i already testes with bufferline pins and it works.

[Iron-E]

So it works now? Might be convenient to write a wrapper like this to ensure the autocmd event always gets fired in the future:

vim.api.nvim_create_user_command( 
  'Mksession',
  function()
    vim.api.nvim_exec_autocmds('User', {pattern = 'SessionSavePre'})
    --[[ session save command here 
         e.g. `vim.cmd.mksession()` 
              or persistence.nvim function ]]
  end,
  {} 
)

---

Edit: interesting. persistence.nvim doesn't have a session save command, it just does everything automatically

---

Edit 2: found the issue. persistence.nvim overrides your sessionoptions on save with these:

options = { "buffers", "curdir", "tabpages", "winsize" }

…which are specified when calling persistence.nvim's setup function. You'll need to add "globals" to this list. As long as persistence.nvim emits SessionLoadPost you shouldn't need to nvim -S either.

(Not sure why they do it this way, instead of just reading sessionoptions directly, but that's neither here nor there)

im already adding globals to persistence. Not working either.

{
    "folke/persistence.nvim",
    event = "BufReadPre", -- this will only start session saving when an actual file was opened
    module = "persistence",
    config = function()
      require("persistence").setup({
        options = { "buffers", "curdir", "tabpages", "winsize", "globals" }, -- sessionoptions used for saving
      })
    end,
  }

Another thing: The buffer order is not being keep too, maybe is something with the load of barbar?

[Iron-E]

@otavioschwanck Just double checking that you run :doautocmd User SessionSavePre before exiting vim.

If so, can you post one of the session files that persistence.nvim is generating? Make sure to censor personally identifying information, I don't need any actual filenames, just the leading setup info.

Since the order of buffers is lost, my guess is that the global barbar session restore variable isn't being stored by persistence.nvim, in which case I'll download the plugin and try it later as well

even using :doautocmd User SessionSavePre it not save.

Looks like it's not saving the global variables. I'll open a separate issue with regards to persistence.nvim and investigate later today— in the meantime, manually running :mksession and nvim -S should work.

the session only saves CamelCase variables, another variables are being save like:

:set g:MyVariable='hello'

reset nvim

:echo g:MyVariable

The global variable from barbar are being saved as CamelCase?
