Binary SAVE/LOAD: SAVE now writes tokenized binary by default (0xFF header format), matching original GW-BASIC behavior. SAVE "file",A for ASCII. LOAD auto-detects binary vs ASCII from the first byte. Command-line file loading also auto-detects, so binary .BAS files just work. INKEY$ extended keys: arrow keys, Home/End/PgUp/PgDn, Insert/Delete, and F1-F10 now return the correct CHR$(0) + scan_code two-byte sequences per the IBM PC convention. Refactored event trap key parsing to use tui_read_key() instead of duplicating escape sequence parsing. Golden-file regression tests: generated .expected output files for 55 of 58 test programs (3 timing-dependent tests excluded). The test runner now reports compat match status alongside pass/fail. Classic programs: added Hamurabi, Lunar Lander, Gunner, and Diamond from David Ahl's BASIC Computer Games (1978) in tests/classic/ for manual compatibility testing. Docs updated with compiler roadmap item and hardware I/O simulator plan.

# Getting Started
|
|
|
|
## Dependencies
|
|
|
|
- C11 compiler (GCC or Clang)
|
|
- CMake 3.10+
|
|
- PulseAudio development library (`libpulse-simple`) — optional, for `SOUND`/`BEEP`/`PLAY`
|
|
|
|
On Debian/Ubuntu:
|
|
|
|
```bash
|
|
sudo apt-get install build-essential cmake libpulse-dev
|
|
```
|
|
|
|
On Fedora/RHEL:
|
|
|
|
```bash
|
|
sudo dnf install gcc cmake pulseaudio-libs-devel
|
|
```
|
|
|
|
## Building
|
|
|
|
```bash
|
|
git clone https://github.com/evvaletov/gw-basic-2026.git
|
|
cd gw-basic-2026
|
|
mkdir -p build && cd build
|
|
cmake .. && make
|
|
```
|
|
|
|
The binary is `build/gwbasic`.
|
|
|
|
## Usage
|
|
|
|
### Interactive Mode
|
|
|
|
Running `./gwbasic` with no arguments launches the full-screen editor:
|
|
|
|
```
|
|
$ ./gwbasic
|
|
GW-BASIC 2026 0.10.0

|
|
Ok
|
|
PRINT 2+2
|
|
4
|
|
Ok
|
|
FOR I=1 TO 5:PRINT I;:NEXT
|
|
1 2 3 4 5
|
|
Ok
|
|
```
|
|
|
|
Use arrow keys to move the cursor freely. Press Enter on any screen line to
|
|
re-enter it. F1-F10 insert common commands (F2 runs the program).
|
|
|
|
### Running a Program File
|
|
|
|
```bash
|
|
./gwbasic tests/programs/prime_sieve.bas
|
|
```
|
|
|
|
### Piped Input
|
|
|
|
```bash
|
|
echo '10 FOR I=1 TO 10:PRINT I*I;:NEXT' | ./gwbasic
|
|
```
|
|
|
|
### Direct Mode Expressions
|
|
|
|
Type expressions and statements at the `Ok` prompt:
|
|
|
|
```
|
|
PRINT SIN(3.14159/2)
|
|
1
|
|
A$="HELLO WORLD":MID$(A$,7,5)="BASIC":PRINT A$
|
|
HELLO BASIC
|
|
```
|
|
|
|
### Command-Line Options
|
|
|
|
