Using snapshots like a .lock file

[YodaEmbedding]

How do I use packer snapshots in the exact same way as a .lock file?

This almost works:

packer.startup {
  packer_spec,
  config = {
    snapshot = util.join_paths(vim.fn.stdpath("config"), "packer-lock.json"),
    snapshot_path = vim.fn.stdpath("config"),
  },
}

...except that it always tries to rollback on every neovim startup, not merely on :PackerSync, which is how .lock files usually work.

Output of :messages:

Rollback to "/home/username/dotfiles/nvim/.config/nvim/packer-lock.json" completed

Also, annoyingly, I have to press enter every time to hide this status message.

I got same question today.

Sadly, snapshots are not intended for that use case. They are just "pictures" (snapshots if you will 😄 ) of certain states of your plugins, so you can go back to them at any moment.
There is already a proposal to provide and use lockfiles #1009 and even a PR.
You can also provide a commit to the plugin configuration. And you can derive that from a snaphsot if you want by using some functions in your neovim config if you want (I have some utility functions to do that)

Having more people test the feature would be a great help. I would also suggest that you watch the issue and PR for changes. I have created a feature proposal and implementation but it might change what it looks like when Wil reviews it.

”pictures“ is great , but it is a little annoyed because snapshot try to roll back everytime when neovim open .

@YodaEmbedding Now Packer.nvim update the SnapShot way . If you want to create a SnapShot , just type the command : PackerSnapShot v1 . v1 just a snapshot name . When you want to rollback , type PackerSnapShot v1 <plugin Name> .

my config:

packer.init(
  {
    snapshot_path = require("packer.util").join_paths(vim.fn.stdpath("config"), "snapshot")
  }
)
