SCons: Format buildsystem files with psf/black 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. 2020-03-30 14:28:32 +08:00			`Import("env")`

SCons: Disable C++ exception handling Upon investigating the extremely slow MSVC build times in #80513, I noticed that while Godot policy is to never use exceptions, we weren't enforcing it with compiler flags, and thus still included exception handling code and stack unwinding. This is wasteful on multiple aspects: - Binary size: Around 20% binary size reduction with exceptions disabled for both MSVC and GCC binaries. - Compile time: * More than 50% build time reduction with MSVC. * 10% to 25% build time reduction with GCC + LTO. - Performance: Possibly, needs to be benchmarked. Since users may want to re-enable exceptions in their own thirdparty code or the libraries they compile with Godot, this behavior can be toggled with the `disable_exceptions` SCons option, which defaults to true. 2023-08-14 19:02:40 +08:00			`if env["disable_exceptions"]:`
