Problem: due to totally async install/update/checkout there is no
guaranteed order of `PackChanged{Pre,}` events across different
plugins. This might lead to conflicts when callback for some "main"
plugin relies on features from "dependency" plugin: i.e. callback for
"main" plugin can trigger before installing/updating "dependency"
plugin. The installation order can be enforced by separate
vim.pack.add() calls, but update/checkout can not.
Solution: Trigger events in bulk independently of async execution:
- `PackChangedPre` before any action for all input plugins in order
they are supplied. It will also trigger even if an action will fail.
- `PackChanged` after all actions finished for all sucessfully
affected plugins in order they are supplied.
This also comes with a couple of side effect changes:
- `PackChangedPre kind=delete` is now also triggered even if the
delete won't be done. This makes it more aligned with `kind=install`
and `kind=update`.
- Force update (`:packupdate!`) and "udpate LSP action" now do two
async steps: download/compute updates and apply them. This also
results in two progress reports.
This is mostly a by-product of the implementation (there has to be
a pre-computation of target revision for all plugins before doing
`PackChangedPre` in bulk before possibly applying an update), but I
kind of like it more this way as it is more explicit of what's going
on. If absolutely not acceptable, there might be some hacks to
mitigate it at least in code action, but I'd keep it like this.
Neovim is a project that seeks to aggressively refactor Vim in order to:
- Simplify maintenance and encourage contributions
- Split the work between multiple developers
- Enable advanced UIs without modifications to the core
- Maximize extensibility

Install from source
See BUILD.md and supported platforms for details.
The build is CMake-based, but a Makefile is provided as a convenience. After installing the dependencies, run the following command.
make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install
To install to a non-default location:
make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=/full/path/
make install
CMake hints for inspecting the build:
cmake --build build --target helplists all build targets.build/CMakeCache.txt(orcmake -LAH build/) contains the resolved values of all CMake variables.build/compile_commands.jsonshows the full compiler invocations for each translation unit.
