As reported by pippin, when gimp-data submodule is not initialized,
meson configuration fails with:
> meson.build:1830:0: ERROR: Nonexistent build file 'gimp-data/meson.build'
This does not give a lot of info, and while the solution can also be
found in INSTALL.in (INSTALL in tarballs) and on developer website, it's
nicer if the build itself could give a clearer information.
Now it will say instead:
> ERROR: Problem encountered: gimp-data submodule not present. Run: git submodule update --init
… found at build-time.
It was working on a machine with default paths and system-installed
packages (e.g. a typical Linux distributions) but needs to be manually
set up e.g. on Windows.
I had the case on my machine where `lua` was version 5.4.4 and the
lua-lgi test succeeded fine, but then the demo plug-in would fail to run
with the error message from #11876.
Let's parse the output of `lua -v` to detect the version ourselves and
therefore be able to output proper error messages for packagers not to
assume that the Lua interpreter they are using will work fine.
See: https://gitlab.gnome.org/GNOME/gimp/-/issues/11876
For 3.0 we will support only Lua 5.1, since we need to figure out how
much of the Lua 5.1 API is compatible with newer versions (Lua minor
versions aren't like Python minor versions, there is API breakage so
plug-ins would be completely unreliable, this commit prevent this).
Also, change some files to not force luajit since it isn't mandatory.
Unlike the other bindings (Lua, JS, Vala) where we only have a demo
plug-in, we actually have a bunch of interesting and useful Python
plug-ins.
Furthermore, we are running several Python scripts through GIMP during
our build (to generate a few images), so pygobject becomes a build
dependency anyway, even if it may not be a run dependency with
-Dpython=disabled.
This all becomes a bit confusing and in fact handling this case (of not
installing Python plug-ins) seems like an annoyance while we lose good
core plug-ins. So let's just make Python plug-ins mandatory. It's not
like Python is very controversial these days, and AFAWK, it is available
on every platform out there.
Commit 81a68ae758 added usage of hb_blob_create_from_file_or_fail().
Since Debian bookworm has harfbuzz 6.0.0, this is not a big deal, but
the minimum requirement should still be bumped in our build scripts.
Without this, build-time GIMP cannot find the etc/ files unless GIMP is
installed. This becomes even more annoying now as I want to run tests
(for GimpUnit) depending on etc/unitrc contents.
This will also ensure that tests run properly in environments where the
etc/unitrc may have been modified.
lua-lgi now works with Lua 5.3 on Windows:
https://github.com/msys2/MINGW-packages/issues/21171
According to my tests, after installing lua53-lgi MSYS2 package,
lua5.3.exe tries to run the goat exercise (fails since the goat
uses different lua API). Anyway, lua5.1 isn't required per se.
1) Right now, MS Partner Center doesn't tell us if the .pdb bunbled as .appxsym
are fine and we only have "Unknow" dumps in the Health page from MS Par. Cen.
My theory, according to my tests with 'SymChk', 'PDBCopy' and 'llvm-pdbutil',
is that this is happening because .pdb from clang or gcc are not "perfect", but
I really have no proof to afirm this, since Partner Center tell us nothing
about them, and we don't even know if the .appxsym were uploaded to begin with.
---
2) The compiler can't generate DWARF (.debug*) symbols when generating .pdb,
which breaks debugging in DrMingw and even lldb according to my tests.
(This is not a fault of the .pdb format but a circumstance: our debuggers
only support DWARF, which is the format already used by MSYS2 packages)
---
So, the .pdb will return probably only in the potential vcpkg transition.
We compile GObject-Introspection anyway (except for cross-builds, where
anyway we don't rely on local Python scripts), so even if not installing
the Python plug-ins, still use them locally.
Creating a temporary config directory for the in-build GIMP (run as a tool or
for unit-testing) is not done as a build target anymore, but in the
in-build-gimp.sh script as a unique temp directory, then cleaned out on exit.
This has a few advantages:
- It is properly cleaned out once the build ends (instead of leaving a full
config dir as trash inside the build dir).
- It is not reused from one build to another (with risk of carrying bugs and
issues over).
- Every use of the in-build GIMP will have its own config directory, and in
particular when they are called in parallel.
As a side update, make sure that all `gimp_exe` runs depend on
`gimp_exe_depends`.
Most of the work in this commit is by @Jehan.
These icons are used only by the .msix (MS Store) distribution of GIMP.
Some legacy icons are used only by Windows 10 and need to have smaller logo
than full image dimensions, so let's not use colorsvg2png. We just pass the
dimensions to use by configuring variants of the same base script.
This makes possible to debug with DIA SDK, if wanted by the developer.
Also, this is needed to create .appxsym files for MS Store debugging.
Ideally meson should be able to install for us, but apparently it doesn't.
See https://github.com/mesonbuild/meson/issues/12977
This line should have never been pushed (in commit a78c41d2a3), my bad! It was
an early (extremely ugly and bad!) attempt to try and have the bindings see the
libraries another way than using DYLD_LIBRARY_PATH (which was instead resolved
with commit 3e980d5ad4).
This omission went unnoticed until I add `set -e` very likely as this failed
command would stop the script in failure.
AppImage is pretty fast to make, like the win crossbuild; and portable,
being very appropriate to do quick tests on Linux when pushing to git.
The overall organization of Debian jobs was changed to take advantage
of this and make things less complicated (but less clear at first sight).
I reinforce that this was the most efficent way to make the AppImage.
The previous commit worked for all the compiled executables, but for Python
plug-ins (and likely all other GObject-Introspected bindings), we need to
generate a temporary typelib linking to the in-build-directory libgimp*
libraries.
This is similar to what the script `package/macports_build_app.sh` does for
packaging in gimp-macos-build repository.
This is now back in sync with how it used to be up to GIMP 2.10. Basically our
API version should always be <major>.0 in the shared libraries naming, as well
as in pkg-config and docs. Otherwise we would break library compatibility with
every minor version bump.
Now the development and stable logos will be generated from gimp-data.
In other changes, the gi-docgen logo is installed as a symlink using
install_symlink() which exists since meson 0.61.0 so I bumped our meson
dependency (in practice we were already using this function anyway and Debian
bookworm has meson 1.0.1 so it's all good).
Finally I don't install a wilber.png anymore, which was only used by script-fu
testing, and which was the same as gimp-logo.png (except 256x256 instead of
128x128). Unless mistaken, all script-fu tests loading this image still work
with the change. The only one where I needed further change was buffer.scm
(which was checking the dimensions).
See gimp-data@9aa6e35.
- Splash images will now be stored from gimp-data.
- The installer BMP image scripts also move in the same time.
- We don't need devel and non-devel variants of the BMP images in InnoSetup
scripts since the images are generated from the actual splash.
Meson subprojects just have too many problems and limitations and I can foresee
the maintenance headache and the future incoming false-positive bug reports if
we start using meson subprojects.
Comparing to the simplicity of git submodule which also has much better
notifications to help people understand when the submodule is not in sync and
how to remedy to it.
See commit gimp-data@c364adb explaining the main reasons in detail.
Note that the executables are not built yet at this point, but we just need to
pass the name for configuration. The gimp.ico generation step is run manually
anyway and requires a fully functional and installed GIMP.
See commit gimp-data@40d4822.
This commit is separate from the previous to make it immediately clear (by
comparing files) that the previous commit is a simple move with no modification
whatsoever of the icons/ directory, i.e. the symmetrical removal of add commit
gimp-data@8b54490.
We now clone gimp-data as a meson subproject. I am currently testing the
subproject feature though I am doubting a bit because of its limitations: the
git clone is not updated automatically, nor are errors clear. Therefore it would
be easy to end up with outdated data for developers not manually and regularly
running:
> meson subprojects update
Worse, it looks like even when updating the suproject, it fails to be properly
reconfigured. See: https://github.com/mesonbuild/meson/issues/12898
With Python binding, it gets very easy to test new functions. I've been
wondering if we need C counterparts, but really since it's a GObject
Introspection binding, if a function succeeds there, it should also succeed in C
code.
For now, I'm testing a few of GimpPalette API. Not all of it yet. Also I test
both the direct C binding and PDB procedure since in some cases, one or the
other may not properly working. See #10885.
One of the big improvement in this commit is that text layers are now much
better at space accuracy. They were already space-aware, yet rendered as sRGB u8
only before being converted to the image's space. It means that text layers had
the following limitations:
* Any color out of sRGB gamut were trimmed.
* Precision was always 8-bit (even if the image was high-bit depth).
Now GimpTextLayout keeps track of its source space (for RGB and CMYK only, this
won't be as easy when we will support more backend, since Cairo has only RGB
support for image data) and the image TRC (in case it bypasses the color space's
TRB) and it draws within this gamut and space.
It means first that we are not limited to sRGB colors; we will draw text main
color in the full image gamut, with still 2 remaining limitations:
* Unbounded colors are impossible because Pango format (to color text) uses
hexadecimal (so even with half/float images, you can't draw out-of-gamut text
unfortunately).
* Main color precision is still 8-bit, yet a tiny bit better than before as we
at least follow TRC (so we avoid some of the precision loss when converting,
even though the bit-depth is still the biggest loss).
The outline color on the other hand is drawn through Cairo API entirely, in
float. This means that the outline color will now be without any precision loss.
Note that this depends on CAIRO_FORMAT_RGBA128F which is only available since
Cairo 1.17.2 which is not in Debian bookworm (our current baseline for GIMP
3.0). It means that the old precision will still happen with older Cairo
version, as determined by #if code at compilation.
In particular in a cross-compilation environment where you don't have an exe
wrapper or cross-host run ability, you still want to be able to configure GIMP.
It is also possible to install lua scripts anyway with -Dlua=enabled, bypassing
ability to test lua-lgi presence (a warning will be outputted at configuration
time, but no error).
The -Dlua option has 3 cases:
1. disabled: lua plug-ins aren't installed at all.
2. auto: lua plug-ins are only installed if we find a lua installation
with access to the 'lgi' module. We now do the actual test at configuration
(not only lua existence test, but also lua-lgi).
3. enabled: lua plug-ins are always installed but if no lua installation with
'lgi' module is found, a warning is displayed at end of configuration step.
As suggested by Jehan, the manifest will be configured by meson.
Of course, for CI compliance, this pushes the job to a further stage:
'packaging', which is what Flatpak is about, after all.
The distribution job name has also been changed, because when Store job
is merged, this will be the new nomenclature of the distribution jobs,
which was not changed since !1171 by lack of time.
This will be needed in particular for GIMP on Windows/Aarch64. Also even on
other OSes, it is useful to support lua plug-ins not only with luajit but also
upstream lua.
… function gimp_font_get_pango_font_description().
Also updating file-pdf-save which is the only plug-in using these right now.
Note that I am not fully happy with the new function
gimp_font_get_pango_font_description() because I experienced some weird behavior
in file-pdf-save which is that some fonts were wrong if this is called after
pango_cairo_font_map_set_resolution().
But let's say this is a first step looking for improvements.
New code uses pango_attribute_as_font_desc() which appeared with Pango 1.50.
Since it's currently present in Debian stable, I don't bother too much and bump
this dependency.
Also let's use the same version for pango, pangocairo and pangoft2. They all
come from the same project/repository, so we must likely expect them to be equal
(if they are not, there is likely a problem).
