Cmake truncates the full link path to a shared library if it is missing
an SONAME in some undocumented scenarios. This causes builds in some
systems to fail if "lpeg" isn't a library on the system path.
The path of imported libraries aren't modified by cmake, so we can use
that as a workaround until a proper solution for this has been
identified.
Closes https://github.com/neovim/neovim/issues/23395.
Currently files to install in runtime/ is detected by recursive glob
pattern which has two problems:
- cmake needs to do a of work at config time and
build/runtime/cmake_install.cmake becomes HUGE (2.5MB, biggest config file)
- we need to explicitly specify each file suffix used in the entire
runtime, which is duplication of information.
These globs specify every single file in a subdirectory.
Thus, we can just install every runtime/ subdirectory as a single
install command. Furthermore, at the top-level, only .vim and .lua files
need to be installed.
Further possible refactor: we could move files which does not belong
in $PREFIX/runtime out of $REPO/runtime. Then runtime could be installed
with a single install_helper(DIRECTORY ...) command.
This change will silence the warning from git describe command when the project
is built using source tarball. The warning is
fatal: not a git repository: 'neovim/.git'
* Remove C++ requirement if test is disabled
* Change CMake package name of C library to msgpack-c
* Unified all C package, library, cmake, tarball name become msgpack-c.
- Remove unused code
- Use consistent casing. Variable names such as LibLuV_LIBRARIES is
needlessly jarring, even if the name might be technically correct.
- Use title casing for packages. find_package(unibilium) requires the
find_module to be named "Findunibilium.cmake", which makes it harder
to spot when scanning the files. Instead, use "Unibilium".
Large parts the library weren't being used, and the parts that were was overly
abstracted for our use case. Additionally, part of its use case was to abstract
pkgconfig boilerplate, which is no longer needed as pkgconfig has been removed
in favor of relying on cmake alone in 09118052ce.
Libuv's recent changes in their pc file breaks cmake; they are using
-l:libuv.a for the linker, and it seems cmake can't resolve that.
Prefer using their cmake config file instead instead, and use the find
module as a fall-back in case it fails.
Closes https://github.com/neovim/neovim/issues/22271.
In Windows, library DLL's are copied in the building process, and a message for each copy is printed. This is useful to have in the log of CI, but annoying to see when you're building and rebuilding nvim constantly. Work around this issue by only enabling the messages on CI.
Eliminates lua-client and non-static libluv as test time dependencies
Note: the API for a public lua-client is not yet finished.
The interface needs to be adjusted to work in the embedded loop
of a nvim instance (to use it to talk between instances)
This makes it easier to see that -D is referring to the entire
"<variable>=<value>", rather than only <variable>. It also help syntax
highlighters highlight built-in variables.
Any logic involving CMAKE_BUILD_TYPE is automatically broken as it won't
work with multi-config generators. The only exception is if we
explicitly check whether the current generator is single-config as well.
Instead, use generator expressions or cmake variables that allows to set
options for certain build types only such as
INTERPROCEDURAL_OPTIMIZATION_<CONFIG>.
Opt to generate all headers with optimization level O2 with no debug
information for all build types as that is the simplest way to make it
behave the same for all generators.
Find modules should only link to libraries defined in the find module,
and not the main project. This helps the find modules be more self-contained and easier to understand.
* build: various cmake refactors and simplifications
- Add STATUS keyword to message to ensure messages are shown in the
correct order.
- Remove DEPS_CXX_COMPILER as we don't rely on C++ for any of our
dependencies.
- Simplify how msgpack and luv configure options are constructed.
- Rely on the default installation for luv instead of manually passing
configure, build and install commands.
- Simplify return code conditional.
* build: remove CMAKE_OSX_ARCHITECTURES_ALT_SEP workaround
CMAKE_OSX_ARCHITECTURES_ALT_SEP was defined as a workaround to prevent
the shell from interpreting `;`, which CMake uses as a list separator.
However, the same thing can be achieved by instead passing
CMAKE_OSX_ARCHITECTURES as a cache variable instead, which is a more
idiomatic way of achieving the same thing.
* build: define CMAKE_BUILD_TYPE before adding it to BUILD_TYPE_STRING
The problem with the current setup is that CMAKE_BUILD_TYPE is defined
after BUILD_TYPE_STRING. BUILD_TYPE_STRING will then be empty on the
first run, meaning that dependencies are built without a build type.
However, since CMAKE_BUILD_TYPE is a cache variable its value will
persist in subsequent runs. On the second run BUILD_TYPE_STRING will
have the correct value, but it's a different value from the ones the
dependencies were built with. This will force some dependencies to be
built again.
Fixes https://github.com/neovim/neovim/issues/21672.
Problem: On Windows, neovim's version is generated every time nvim is
built, even if code hasn't been changed. That is because version
generation is done based on a hash matching of a file and the content of
the file. And in Windows they don't match, because of the DOS
line-endings.
Solution: Write the file containing nvim version with UNIX line-endings.
clint takes around 5-10 seconds to lint tui/terminfo_defs.h. For CI this
is negligible, but it's annoying for local development as touching
terminfo_defs.h will skyrocket lint times. Furthermore, we have no
reason to touch or modify terminfo_defs.h as it's a generated file, so
linting it shouldn't be necessary. This should speed up "make lint" by
the same amount, so around 5-10 seconds.
Fix remaining clint errors and remove error suppression completely.
Rename the lint targets to align with the established naming convention:
- lintc-clint lints with clint.py.
- lintc-uncrustify lints with uncrustify.
- lintc runs both targets.
lintc is also provided as a make target for convenience.
After this change we can remove these files:

Replace old-school cmake with the so-called "Modern CMake", meaning
preferring using targets and properties over directory settings and
variables. This allows greater flexibility, robustness and clarity over
how the code works.
The following deprecated commands will be replaced with their modern
alternatives that operates on a specific target, rather than all targets
in the current directory:
- add_compile_options -> target_compile_options
- include_directories -> target_include_directories
- link_libraries -> target_link_libraries
- add_definitions -> target_compile_definitions
There are mainly four main targets that we currently use: nvim, libnvim,
nvim-test (used by unittests) and ${texe} (used by
check-single-includes). The goal is to explicitly define the
dependencies of each target fully, rather than having everything be
dependent on everything else.
EXCLUDE filters out all elements containing regex, meaning it works on
both files and directories.
Also rename add_glob_targets to add_glob_target since only one target is
being created.
- Prevent duplicate version strings such as v0.8.0-v0.8.0.
- Change the format for git releases from v0.9.0-dev-67-g625ba79be to
v0.9.0-dev-67+g625ba79be.
Nvim versions are now:
release : v0.9.0
prerelease without git info: v0.9.0-dev
prerelease with git info : v0.9.0-dev-67+g625ba79be
This partially reverts commit 42aeb5c5b1.
Setting cmake policies is normally not required as
cmake_minimum_required automatically sets these. One exception is cmake
script mode (-P) since it automatically resets all policy changes.
Closes: https://github.com/neovim/neovim/issues/20286
Add --always flag to `git describe` so version generation succeeds if
current directory is in a git repo. If not in git repo, fall back to a
default version in the format vx.y.z-dev
Change the default build type to always be Debug, and allow only four
predefined build types: Debug, Release, RelWithDebInfo and MinRelSize.
Furthermore, flags meant for single-configuration generator (make,
ninja) will not be used for multi-configuration generators (visual
studio, Xcode), and flags meant for multi-configuration generators will
not be used for single-configuration generators.
This will allow Debug builds to be built with MSVC which requires that
all dependencies are also built with the Debug build type to avoid
runtime library mismatch.
The correct way to specify build type (for example Release) for
single-configuration generators (Make and Ninja) is to run
cmake -B build -D CMAKE_BUILD_TYPE=Release
cmake --build build
while for multi-configuration generators (Visual Studio, Xcode and Ninja
Multi-Config) is to run
cmake -B build
cmake --build build --config Release
Passing CMAKE_BUILD_TYPE for multi-config generators will now not only
not be used, but also generate a warning for the user.

- Use DIRECTORY instead of PATH in get_filename_component
- Use COMPILE_OPTIONS instead of COMPILE_FLAGS. COMPILE_FLAGS is treated
as a single string while COMPILE_OPTIONS is a list, meaning that cmake
will take care of any escaping and quoting automatically.
