AstroNvim v2.11.8 on the current main branch

In order to update AstroNvim to the current main branch (which is also nightly branch), Neovim needed to be updated v0.8+. Since the official Debian package was stuck at v0.7, I installed the upstream provided deb package. See Debian BTS #1021339.

The following configuration was built on top of the configuration mentioned in Re-learning Vim (5).

Local customization

I customized my Neovim with ~/.config/astronvim and installed a few extra packages as astronvim-osamu.

Key local features:

vimdoc-install script to make all available Vimhelp documentation easily accessible via :h by creating symlinks in ~/.config/astronvim/doc/ directories to them.

Treesitter language support

Treesitter supports for pertinent languages were installed as:

:TSInstall {language}

See :h nvim-treesitter

LSP/DAP/Linter/Formatter language support

LSP/DAP/Linter/Formatter supports for pertinent languages were interactively installed by <leader>pI or :Mason.

Basically, this helps us to install requested <packagename> package into ~/.local/share/nvim/mason/packages/<packagename>/ and make its executable <progname> program accessible from Neovim in ~/.local/share/nvim/mason/bin/<progname>. So executable programs from Neovim plugins are not the one on the main system.

In order this to work, some system programs are needed to be installed in advance. As I see my situation with :checkhealth mason.nvim (after mason.nvim has been delay loaded by opening a file).:

mason: require("").check()

I ended up to install following Debian packages as required system programs.

See more :h mason.nvim

In order to make LSP/DAP/Linter/Formatter programs accessible from shell prompt, I have modifies ~/.profile to include the following:

# set PATH so it includes mason.nvim's private bin if it exists (Neovim/mason.nvim)
if [ -d "$HOME/.local/share/nvim/mason/bin/" ]; then

I got annoyed with automatic reformat upon file save. The upstream gave me a lesson pointing me to a solution.

I also added ~/.editorconfig to cope with sources using editorconfig.

AstroNvim on v3 branch with lazy.nvim

It looks like AstoNvim is migrating to the new package manager lazy.nvim as I see its v3 branch development.

Once we migrate, files under ~/.local/share/nvim/site/pack/packer seem to be safely removed after migration.
