Problem: Installing treesitter parser is hard (harder than
climbing to heaven).
Solution: Add optional support for wasm parsers with `wasmtime`.
Notes:
* Needs to be enabled by setting `ENABLE_WASMTIME` for tree-sitter and
Neovim. Build with
`make CMAKE_EXTRA_FLAGS=-DENABLE_WASMTIME=ON
DEPS_CMAKE_FLAGS=-DENABLE_WASMTIME=ON`
* Adds optional Rust (obviously) and C11 dependencies.
* Wasmtime comes with a lot of features that can negatively affect
Neovim performance due to library and symbol table size. Make sure to
build with minimal features and full LTO.
* To reduce re-compilation times, install `sccache` and build with
`RUSTC_WRAPPER=<path/to/sccache> make ...`
Problem: Adding support for modern Nvim features (reflow, OSC 8, full
utf8/emoji support) requires coupling libvterm to Nvim internals
(e.g., utf8proc).
Solution: Vendor libvterm at v0.3.3.
utf8proc contains all the data which is currently in
unicode_tables.generated.h internally, but in quite a different format.
Ideally unicode_tables.generated.h should be removed as well so we rely
solely on utf8proc. We want to avoid a situation where the possibility
of unicode mismatch occurs, e.g a distro using both unicode 12 and
unicode 13.
This will reduce friction as developers no longer need to provide a hash
when testing out different commits.
To skip the hash check, set `DEPS_IGNORE_SHA` to `TRUE` in
`cmake.deps/CMakeLists.txt`.
Debugging dependencies is rare so a Debug build type is usually not
needed. In cases where it _is_ needed it is easy to rebuild in Debug
mode. But since Release builds are more common, it makes more sense as a
default.
For Neovim itself we stick with a Debug build as a default, since
rebuilding and debugging is done _much_ more frequently than with
dependencies (which we _mostly_ expect to "just work").
Also remove the CMAKE_BUILD_TYPE variable in the Makefile, since this is
set by default in CMake.
- remove "ran-" prefix from touch files as it's redundant since the
they're already in the directory named `touches`.
- Include `contrib` when formatting with `make formatlua`.
- Use TARGET_FILE generator expression instead of assuming the
executable location.
- reuse logic that determines whether to use lua or luajit.
- add translations to the `nvim` target.
Makefile improvements:
- rename variable `CMAKE_PRG` to `CMAKE` to make it more consistent with
the builtin `MAKE` variable.
- stop propagating flags to generator. Users should use cmake for
non-standard use cases.
- remove `+` prefix from targets. If the user for whatever reason wants
to dry-run a target then they should be able to.
- add EXTERNALPROJECT_OPTIONS variable to main build
- use `REQUIRED` keyword for IWYU.
- remove check_c_compiler_flag checks when `ENABLE_COMPILER_SUGGESTIONS`
is `ON`. If we explicitly enable it then we probably want it to give
an error if it doesn't exist, rather than silently skip it.
- Move dependency interface libraries to their find module and use them
as a pseudo-imported target.
- Remove BUSTED_OUTPUT_TYPE. It's not used and we can reintroduce it
again if something similar is needed.
- Use LINK_OPTIONS intead of LINK_FLAGS when generating the `--version`
output.
The benefits are primarily being able to use FetchContent, which allows
for a more flexible dependency handling. Other various quality-of-life
features such as `-B` and `-S` flags are also included.
This also removes broken `--version` generation as it does not work for
version 3.10 and 3.11 due to the `JOIN` generator expression.

- Correct MSVC warning suppression. The C4003 warning is issued during
file generation and not for the actual source files.
- Remove non-existent "scripts/pvscheck.sh" file from `lintsh` target.
- Remove spaces inside for loops with uncrustify.
- Point dependencies to use a git tag rather than releases, as releases
might have changes that deviate from the actual source code.
- Automatically update uncrustify config before formatting or linting.
We do not have any patches that we use at the moment, so git is not
needed right now. Futhermore, we've become more strict with not adding
patches, which makes it pretty safe to remove this for the time being.
- silence false warnings on MSVC
- merge `clang-tidy` cmake target into `lintc` and remove the
corresponding make target
- use cmake's built-in endianness detection
Now that all the Find<Foo>.cmake modules are using our custom
find_path2, the bundled deps build needs to include the Find module so
it has access to find_path2.
The missing include was causing the PPA build to fail:

Neovim QT was originally bundled on Windows as a response to the then
lackluster terminal options. The situation has dramatically changed,
with viable options such as Windows terminal, Alacritty and Wezterm to
name a few. The Windows build no longer needs this special treatment for
neovim to be usable.
Pros:
- Release builds will be smaller.
- Less maintenance burden.
- Clearer separation of responsibility (neovim issues go to the neovim
repo and neovim-qt issues to the neovim-qt repo).
- More consistent treatment between platforms.
Cons:
- Users who've come to expect neovim-qt to be bundled with nvim will
need to adjust and download neovim-qt from
https://github.com/equalsraf/neovim-qt instead.
- Similarly, build scripts will need to be adjusted to reflect this
change.
Closes https://github.com/neovim/neovim/issues/21209.
Uncrustify is sensitive to version changes, which causes friction for
contributors that doesn't have that exact version. It's also simpler to
download and install the correct version than to have bespoke version
checking.
- Simplify error checking when using execute_process.
- Set BUILD_SHARED_LIBS to OFF when building dependencies.
This is normally not needed, but msgpack interprets an unset
BUILD_SHARED_LIBS to build a shared library, which is the opposite of
the cmake behavior.
- Move function check_lua_module to Util.cmake.
- Remove unnecessary code.
- Make variable naming more consistent
Cmake won't rebuild with the new URL when bumping dependency version.
This is because the old URL is still cached, and won't be removed
automatically. The workaround for using non-cached variables, but also
let users specify an alternative URL is to only set the defined
variables in deps.txt if the corresponding variable hasn't already been
set by the user from the command line.
Also apply the CMAKE_CONFIFGURE_DEPENDS property to deps.txt, as we want
cmake to rebuild when changing this file.
The cmake.deps build will read this file and set the left part of the
text as the variable name and the right part as the variable value. The
benefit of doing this is that it becomes much easier to parse which
dependencies are required, as well as to bump dependencies with
scripts/bump_deps.lua.
Adjust bump_deps.lua script to work with this new format.
The shipped versions of xdiff already does everything diff does, so this
duplication of tools isn't necessary. Furthermore, this setup is more
consistent overall, as the 'diffopt=external' option should be for
external programs rather than programs we bundle neovim with.
Install diffutils for oldtests in CI to avoid needing to modify tests.
Currently, the release build picks up headers in
`/Library/Frameworks/Mono.framework/Headers`. You can verify this by
downloading the latest nightly build and checking the output of `nvim
--version`.
These headers are likely to be from a different version of `libintl` than the
one we link to. Let's avoid usage of them by setting `CMAKE_FIND_FRAMEWORK` to
`NEVER`.
Problem: tree-sitter-viml parser was not maintained and missing a
release, making it difficult for distros to package Neovim.
Solution: fork the parser under the neovim org, merge some outstanding
PRs, perform general cleanup, make a release, and use this for the
build.
Problem: www.leonerd.org.uk is sometimes unreachable
Solution: switch to Launchpad URLs for libvterm (official page) and
libtermkey (source mirror for Ubuntu package)
The wintools executables are stored in a zip file, making it
inconvenient to bump these during releases. Instead, unpack the
executables in the deps repository and download each executable
separately.
Older gcc versions (4.x) require passing --std=c99 compiler flag to
prevent warnings from being emitted. Instead of setting it for each
dependency, it's easier to just pass the CMAKE_C_STANDARD flag to all
dependencies. This also prevents the scenario of us forgetting to set it
if we add new dependencies.
Neovim and the generated headers needs to use the same include
directories to build correctly. However, we need to generate headers
before all target dependencies has been resolved, meaning that we cannot
rely on any target to determine the final list of include directories.
This may lead to a problems when bundling some, but not all or none,
dependencies as the dependency include directory won't be included.
Also remove the dependency path options as this assumes a specific
structure on the dependency build directory.
We provide options such as "DEPS_BIN_DIR" for the user to set, but only
sometimes use them. This makes binaries and other files to be spread out
if the user defines a custom DEPS_BIN_DIR location.
