Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Proper usage of opts table rather than setting things up with the config function.

how do you remove mapping. set_mappings seems to only set ?

I'll handle this :)

@rameshsanth I modified this implementation a bit to integrate a bit more seamlessly with AstroCore and make the mapping more easily configurable by the user. This also makes it a bit easier to start venn mode by setting up a user command :VennToggle.

It's also important to note that this plugin's method of setting up the buffer mappings is pretty bad and comes in and clobbers any previous buffer local mappings such as K which is used for LSP documentation. So any buffer that uses a language server will have at least that mapping borked after toggling venn mode. Not sure the best way to fix this other than caching already existing mappings on enable and restoring them on disable. Not sure if you want to implement that or not. I think as is this is fine enough to merge since it implements exactly what the README for that plugin recommends even though it's a bad recommendation.

@rameshsanth I actually just added Hydra.nvim to AstroCommunity in a way that it can be integrated with other plugins. I modified this config so that if hydra is available it defines the diagramming mode as a submode in Neovim (As described here: https://github.com/anuvyklack/hydra.nvim/wiki/Draw-diagrams)

If you want to try it out simply add hydra from AstroCommunity :)
