Switch back to Ubuntu 18.04 for buliding the appimage. This allows for
using the appimage on older systems that do not provide GLIBC_2.29.
Fixes#19711.
Fixes#20113.
Skipping the CI on documentation-only changes is no longer appropriate
as we now rely on CI to test parts of documentation, e.g.
test/functional/lua/help_spec.lua.
Ignore changes in contrib/ as it's for non-essential user contributions
that we don't need to test.
It's a leftover artifact that currently just acts as an unnecessary
intermediary script that calls the Makefile. It can be replaced by just
calling the Makefile directly.
Our previous mangling of gettext broke the `HAVE_WORKING_LIBINTL` test
because it prevented CMake from finding `libintl.h`. Let's fix that by
linking Gettext's `include` directory into `/usr/local` too.
Problem:
Dirs "config", "packaging", and "third-party" are all closely related
but this is not obvious from the layout. This adds friction for new
contributors.
Solution:
- rename config/ to cmake.config/
- rename test/config/ to test/cmakeconfig/ because it is used in Lua
tests: require('test.cmakeconfig.paths').
- rename packaging/ to cmake.packaging/
- rename third-party/ to cmake.deps/ (parallel with .deps/)
After some tweaks to our dep builds, we can now build a universal binary
for macOS by using `CMAKE_OSX_ARCHITECTURES`. So, let's do that. This
requires a number of additional changes:
1. We need to build on macOS 11, since earlier versions do not support
building universal (M1 + Intel) binaries.
2. We need to provision a universal `libintl`. The linker will look for
an ARM64 version of this library when linking the `nvim` binary.
While we're here:
1. Link statically to `libintl`. This allows to to avoid having to do
any install name rewriting or codesigning to package Neovim.
2. Bump the `MACOSX_DEPLOYMENT_TARGET` to `11`. We're already using a
`libintl` built by Homebrew (through the pre-installed version of
`gettext`), and that is built for macOS 11.
In order to ensure we link to `libintl.a` instead of `libintl.dylib`, we
have to make sure that CMake can't find the latter. This ideally should
be a matter of doing `brew unlink gettext`. However, CMake is too adept
at finding things that Homebrew has installed (even when not linked), so
we have to do a bit more than that. This appears in the additional step
ensuring static linkage to `libintl`.
We end up breaking some Homebrew-installed software in the process, and
some of these software is called during our build (e.g. curl, git,
wget). To avoid any adverse effects, let's just uninstall them.
Problem:
The release script bundles a system library (CoreServices) that was
added in #18294, which leads to errors on M1 since the architecture is
different from the Github runner.
Solution:
Skip CoreServices when bundling the libraries (as was done for the
CoreFoundation library that #18294 replaced with CoreServices).
* build: move the logic for linters to cmake
Cmake is our source of truth. We should have as much of our build
process there as possible so everyone can make use of it.
* build: remove redundant check for ninja generator
The minimum cmake version as of writing this is 3.10, which has ninja
support.
Since we're not running tests or other things that are more sensitive to
changes in the VM environment, use ubuntu-latest to avoid the busy work
of updating the VM image.
