Previously, all of the code generation routines would just needlessly
write the same files over and over, even when not needed.
This became a problem with the advent of the experimental ninja backend
for SCons, which can be trivially enabled with a few lines of code and
relies on timestamp changes, making it thus impractical.
- Extract individual components to their own files.
- Improve order of declarations and definitions within those files.
- ProjectDialog is only extracted as there are upcoming
PRs touching on it.
This change introduces a new EditorThemeManager class
to abstract theme generatio and its subroutines.
Logic related to EditorTheme, EditorColorMap, and editor
icons has been extracted into their respective files with
includes cleaned up.
All related files have been moved to a separate folder to
better scope them in the project. This includes relevant
generated files as well.
Also start organizing editor-specific GUI components
into a dedicated folder, `editor/gui`.
Also move `editor_file_server` next to the rest of debugger classes.
- Separate editor interface and property translations.
- Add property translation in TranslationServer.
- The split and merge of the POT/PO/Makefiles and extract scripts is done
directly in godot-editor-l10n, the files will be removed in the next commit.
- Remove the hardcoded "to_include" lists from the SCsub, we'll only commit the
files which are ready to inclue.
Implements https://github.com/godotengine/godot-proposals/issues/3371.
New `target` presets
====================
The `tools` option is removed and `target` changes to use three new presets,
which match the builds users are familiar with. These targets control the
default optimization level and enable editor-specific and debugging code:
- `editor`: Replaces `tools=yes target=release_debug`.
* Defines: `TOOLS_ENABLED`, `DEBUG_ENABLED`, `-O2`/`/O2`
- `template_debug`: Replaces `tools=no target=release_debug`.
* Defines: `DEBUG_ENABLED`, `-O2`/`/O2`
- `template_release`: Replaces `tools=no target=release`.
* Defines: `-O3`/`/O2`
New `dev_build` option
======================
The previous `target=debug` is now replaced by a separate `dev_build=yes`
option, which can be used in combination with either of the three targets,
and changes the following:
- `dev_build`: Defines `DEV_ENABLED`, disables optimization (`-O0`/`/0d`),
enables generating debug symbols, does not define `NDEBUG` so `assert()`
works in thirdparty libraries, adds a `.dev` suffix to the binary name.
Note: Unlike previously, `dev_build` defaults to off so that users who
compile Godot from source get an optimized and small build by default.
Engine contributors should now set `dev_build=yes` in their build scripts or
IDE configuration manually.
Changed binary names
====================
The name of generated binaries and object files are changed too, to follow
this format:
`godot.<platform>.<target>[.dev][.double].<arch>[.<extra_suffix>][.<ext>]`
For example:
- `godot.linuxbsd.editor.dev.arm64`
- `godot.windows.template_release.double.x86_64.mono.exe`
Be sure to update your links/scripts/IDE config accordingly.
More flexible `optimize` and `debug_symbols` options
====================================================
The optimization level and whether to generate debug symbols can be further
specified with the `optimize` and `debug_symbols` options. So the default
values listed above for the various `target` and `dev_build` combinations
are indicative and can be replaced when compiling, e.g.:
`scons p=linuxbsd target=template_debug dev_build=yes optimize=debug`
will make a "debug" export template with dev-only code enabled, `-Og`
optimization level for GCC/Clang, and debug symbols. Perfect for debugging
complex crashes at runtime in an exported project.
This reduces the size of the editor binaries significantly, as we otherwise
embed all WIP translations, including ones with very low completion ratios,
and end up paying for the size of all `msgid`s for each locale.
Cf. https://github.com/godotengine/godot-proposals/issues/3421 for details.
The thresholds used are:
- 30% for the editor interface (should already include most common strings
while more obscure ones like UndoRedo action names might be untranslated).
- 10% for the class reference: this is a HUGE resource and 10% is already
a lot of useful content, especially if focused on the most used APIs.
This currently reduces the size of the editor binary by 17% on Linux.
The list will be synced manually every now and then.
(cherry picked from commit 8425c58991)
Whenever we change the name (or remove) generated cpp files with the `.gen.cpp`
extension, users run into build issues when switching between branches (i.e.
switching before and after the name change/removal). This is because we glob
`*.cpp` so if a now-obsolete file from a previous build is present, we'll
include it too, potentially leading to bugs or compilation failure (due to
missing headers or invalid code).
So globbing patterns in `add_source_files` will now skip files ending with
`.gen.cpp`, which should instead be passed explicitly where they're used.
A new `env.Run` method is added which allows to control the verbosity
of builders output automatically depending on whether the "verbose"
option is set. It also allows to optionally run any SCons commands in a
subprocess using the existing `run_in_subprocess` method, unifying
the interface. `Action` objects wrap all builder functions to include a
short build message associated with any action.
Notably, this removes quite verbose output generated by `make_doc_header`
and `make_editor_icons_action` builders.
This patch adds ability to include external, user-defined C++ modules
to be compiled as part of Godot via `custom_modules` build option
which can be passed to `scons`.
```
scons platform=x11 tools=yes custom_modules="../project/modules"
```
Features:
- detects all available modules under `custom_modules` directory the
same way as it does for built-in modules (not recursive);
- works with both relative and absolute paths on the filesystem;
- multiple search paths can be specified as a comma-separated list.
Module custom documentation and editor icons collection and generation
process is adapted to work with absolute paths needed by such modules.
Also fixed doctool bug mixing absolute and relative paths respectively.
Implementation details:
- `env.module_list` is a dictionary now, which holds both module name as
key and either a relative or absolute path to a module as a value.
- `methods.detect_modules` is run twice: once for built-in modules, and
second for external modules, all combined later.
- `methods.detect_modules` was not doing what it says on the tin. It is
split into `detect_modules` which collects a list of available modules
and `write_modules` which generates `register_types` sources for each.
- whether a module is built-in or external is distinguished by relative
or absolute paths respectively. `custom_modules` scons converter
ensures that the path is absolute even if relative path is supplied,
including expanding user paths and symbolic links.
- treats the parent directory as if it was Godot's base directory, so
that there's no need to change include paths in cases where custom
modules are included as dependencies in other modules.
Configured for a max line length of 120 characters.
psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:
- Manually wrapped strings will be reflowed, so by using a line length
of 120 for the sake of preserving readability for our long command
calls, it also means that some manually wrapped strings are back on
the same line and should be manually merged again.
- Code generators using string concatenation extensively look awful,
since black puts each operand on a single line. We need to refactor
these generators to use more pythonic string formatting, for which
many options are available (`%`, `format` or f-strings).
- CI checks and a pre-commit hook will be added to ensure that future
buildsystem changes are well-formatted.
Now that the unused DocDump was removed, the `editor/doc` subfolder is
redundant.
Similarly, there's no reason for Collada to have a subfolder for itself
when glTF or OBJ don't.
- Parse `.po` files from `doc/translations/*.po` like already done
with `editor/translations/*.po`.
- Add logic to register a doc translation mapping in `TranslationServer`
and `EditorSettings`.
- Add `DTR()` to lookup the doc translation mapping (similar to `TTR()`).
Strings are automatically dedented and stripped of whitespace to ensure
that they would match the translation catalog.
- Use `DTR()` to translate relevant strings in `EditorHelp`,
`EditorInspector`, `CreateDialog`, `ConnectionsDialog`.
- Small simplification to `TranslationLoaderPO`, the path argument was
not really meaningful.
Also added support for SCons project-absolute paths (starting with #) and
warning about duplicates in add_source_files(), and fixed
default_controller_mappings.gen.cpp being included twice after first build
due to *.cpp globbing.
Part of #30270.
Reverts "Build polygon clipper only in tools builds" (see #17319)
which allows to build Clipper with tools disabled (release) and because
of that, Clipper has to be patched to optionally disable exceptions in
order to be built on some platforms.
Patched Clipper 6.4.2 to be compiled with exceptions enabled/disabled.
and ensure that Clipper-specific exception macros are defined: don't use
exceptions by default unless exception handling is detected.
Compilation with exceptions will be determined by various
C++ exceptions defines:
* ` __cpp_exceptions` is part of C++ feature testing macros (since C++98);
* `__EXCEPTIONS` is used by some GNU compilers;
* `_CPPUNWIND` is used by MSVC.
The user can override specific exceptions behavior via corresponding
`*_USER` macros (i.e. compiling for embedded systems).
Also finally move freetype to its own env and disable warnings for it.
Still needs some work to fix the awkward situation of the freetype and
svg modules used in scene/ and editor/ respectively.
If this is undesired it can be avoided by specifying builtin_certs=no .
Bundled SSL certs will be used unless you specify an override in:
Project Settings -> SSL -> Certificates .
so that godot package builds reproducibly
in spite of indeterministic filesystem readdir order
and http://bugs.python.org/issue30461
See https://reproducible-builds.org/ for why this is good.
Sort font input file list, so that builtin_fonts.gen.h
is created in a reproducible way
Sort list of platforms, so that editor/register_exporters.gen.cpp
is created in a reproducible way
Sort list of source files, so that .a files and resulting godot binaries
are created in a reproducible way
We want to add the individual strings to the list
and not add a list object to the list.
Without this patch, sorting failed because "str < list"
is not a valid operation in python.
- Refactored all builder (make_*) functions into separate Python modules along to the build tree
- Introduced utility function to wrap all invocations on Windows, but does not change it elsewhere
- Introduced stub to use the builders module as a stand alone script and invoke a selected function
There is a problem with file handles related to writing generated content (*.gen.h and *.gen.cpp)
on Windows, which randomly causes a SHARING VIOLATION error to the compiler resulting in flaky
builds. Running all such content generators in a new subprocess instead of directly inside the
build script works around the issue.
Yes, I tried the multiprocessing module. It did not work due to conflict with SCons on cPickle.
Suggested workaround did not fully work either.
Using the run_in_subprocess wrapper on osx and x11 platforms as well for consistency. In case of
running a cross-compilation on Windows they would still be used, but likely it will not happen
in practice. What counts is that the build itself is running on which platform, not the target
platform.
Some generated files are written directly in an SConstruct or SCsub file, before the parallel build starts. They don't need to be written in a subprocess, apparently, so I left them as is.
