Examples

The checkout includes example programs under examples/. They are useful for learning the language surface, checking library behavior, and exercising larger application shapes than a single hello-world file.

Run the example launcher after installation:

./install.sh
./demos.sh list
./demos.sh all

./demos.sh all builds and runs the batch demos. Interactive and GUI demos are listed but are not run automatically by the batch mode.

Batch demos

Name	Source	Shows
`primes`	`examples/primes/sieve.pas`	Sieve of Eratosthenes.
`sudoku`	`examples/sudoku/sudoku.pas`	Backtracking solver.
`factorial`	`examples/bignum/factorial.pas`	Big-integer factorial.
`bigmath`	`examples/bignum/bigmath.pas`	Arbitrary-precision arithmetic.
`json`	`examples/json/jsondemo.pas`	JSON parse and emit.
`sat`	`examples/sat/satdemo.pas`	DPLL SAT solver.
`mathf`	`examples/mathf/mathdemo.pas`	Floating-point math helpers.
`maze`	`examples/maze/maze.pas`	Maze generation.
`mandelbrot`	`examples/mandelbrot/mandelbrot.pas`	ASCII Mandelbrot output and interactive TUI explorer.
`vm`	`examples/vm/vmdemo.pas`	Tiny bytecode VM.

Build one directly:

./pxx examples/json/jsondemo.pas /tmp/jsondemo
/tmp/jsondemo

Interactive terminal demos

Name	Source	Shows
`life`	`examples/life/life.pas`	Terminal animation.
`calc`	`examples/calc/calcdemo.pas`	Expression calculator.
`lisp`	`examples/lisp/lispdemo.pas`	Small REPL.
`chess`	`examples/chess/chess.pas`	Console engine.
`adventure`	`examples/adventure/adventure.pas`	Text adventure.
`2048`	`examples/g2048/console_2048.pas`	Terminal game.
`solitaire`	`examples/solitaire/console_solitaire.pas`	Terminal card game.
`menu`	`examples/tui/menudemo.pas`	Terminal UI widgets.

Run these through the launcher so the terminal interaction is clear:

./demos.sh

GUI demos

GUI demos need the relevant desktop libraries and a display server. The launcher builds them and prints the generated executable path instead of launching every GUI program automatically.

Name	Source	Shows
`triangle`	`examples/gl/triangle.pas`	OpenGL setup.
`solitaire-gui`	`examples/solitaire_gui/solitaire_gui.pas`	GUI card-game surface.
`fm`	`examples/fm/fm.pas`	GTK file manager.
`player`	`examples/player/player.pas`	GTK media-player shell.

Apps

apps/ide/ is a larger application built with PXX: a single-window IDE, Lazarus/Delphi-inspired but deliberately stripped down (no multi-window, no modal forms, no scattered subwindows — everything tiled in one window). It doubles as a real-world stress test for the compiler.

The components use a Hebrew naming scheme, all transliterating names tied to the prophet Elijah and the theme of testimony/witness:

Name	Hebrew	Meaning	Role
`garin`	גרעין	kernel / core	Render-agnostic engine: editor buffer, project model, the designed-form document, the builder. Both faces grow from this seed.
`eliah`	אליה	Elijah	GTK face (posix + GTK) — the graphical IDE window.
`ilja`	איליה	Elijah	ANSI/TUI face (posix + terminal) — same prophet, second face.
`bochan`	בוחן	examiner	Headless test driver for `garin`. Links no GUI/TUI face, proving the core is render-agnostic.
`eduth`	עדות	testimony	The validator `bochan` reports to: witnesses results, tallies pass/fail, yields a verdict.

Build and run the GTK face with the pinned stable compiler:

apps/ide/build.sh
apps/ide/eliah/eliah

Run the headless core test gate (no GUI library on the search path):

apps/ide/test.sh

Networking demo

The networking demo has its own notes in examples/net/README.md. It runs a loopback HTTP server and client on one coroutine reactor thread, so it does not need an external network service:
