Cogito

Get rational about GUI.

Requirements

• C compiler (cc) with C11 support
• Meson
• Ninja
• SDL3
• SDL3_ttf
• freetype2
• SDL3_image (optional, used for themed icon file loading)
• (Optionally) Yis compiler [for extras folder apps]

Example (macOS/Homebrew):

brew install meson ninja sdl3 sdl3_ttf sdl3_image freetype

SUM Theme Validator

Validate Cogito SUM themes (including @bring expansion with source-mapped diagnostics):

./yis/build/yis sum validate cogito/examples/sum_validator_fixtures/theme.sum
./yis/build/yis sum validate --mode off cogito/examples/sum_validator_fixtures/theme.sum
./yis/build/yis sum validate --mode strict cogito/examples/sum_validator_fixtures/theme.sum
./yis/build/yis sum validate cogito/examples/sum_validator_fixtures

Fixtures for validator behavior are in:

cogito/examples/sum_validator_fixtures/

Build Cogito

Build the Cogito shared library in its own build directory:

meson setup cogito/build cogito
meson compile -C cogito/build

Then run GUI examples with Yis:

./yis/build/yis run cogito/examples/gui_hello.yi
./yis/build/yis run cogito/examples/gui_gallery.yi

If your program uses Cogito, include:

bring cogito

Install Cogito library and headers:

meson install -C cogito/build

• YIS_COGITO_CFLAGS: extra C flags for Cogito
• YIS_COGITO_FLAGS: extra linker flags for Cogito
