Add event-driven programming: ON TIMER(n) GOSUB with TIMER ON/OFF/STOP,
ON KEY(n) GOSUB with KEY(n) ON/OFF/STOP for F1-F10. Fix F-key escape
sequence parser (F9/F10 detection, push back consumed bytes on unmatched
sequences). Add EDIT statement for TUI line editing. Guard key trap
polling so keystrokes aren't consumed when no traps are configured.
LPRINT and LLIST now output to a printer device or file instead of the
screen. By default, output is appended to LPT1.TXT in the current
directory. Use --lpt to redirect to a real printer device (/dev/lp0,
LPT1 on FreeDOS) or a custom file path.
Includes full PRINT format support (semicolons, commas, TAB, SPC,
PRINT USING) and LLIST with line number range parsing.
The TUI screen buffer is now dynamically allocated instead of using a
fixed 25x80 array. When launched with --full/-f, the editor queries the
terminal size via ioctl(TIOCGWINSZ) and adapts accordingly. The default
remains the authentic 25x80.
AUTO generates line numbers during interactive editing, RENUM
renumbers program lines and patches all GOTO/GOSUB/ON references,
DELETE removes line ranges. COMMON declares variables preserved
across CHAIN. Also fixed LIST/DELETE range parsing (was broken by
expression evaluator consuming the dash as subtraction).
Bump to v0.7.0, 53 tests.
DATE$, TIME$, and TIMER now return real system date/time instead of
hardcoded values. Added directory and shell access statements with
proper GW-BASIC error codes (Path not found 76, File already exists 60).
Bump to v0.6.0, 52 tests.
Authentic GW-BASIC screen editor with 25x80 buffer, free cursor movement,
enter-on-any-line, F1-F10 function keys, Insert/Overwrite toggle, KEY
ON/OFF/LIST statement, and Ctrl+Break handling. HAL pointer swap routes
all PRINT/LIST/error output through the TUI automatically. Piped mode
unchanged (50/50 tests pass).
Adds automated compatibility testing infrastructure: DOSBox-X headless
config, PRINT-to-file transform script, and run_compat.sh with --generate
and --compare modes for verifying output against real GWBASIC.EXE.
Project renamed from gwbasic-c to GW-BASIC 2026.
- Tokenizer now copies entire identifier (letters+digits) when no
keyword matches, fixing variables like K2, V1, AB3%
- ERL returns actual error line number instead of 0
- Update README and Sphinx docs for v0.5.0
Add README.md for public release. Implement KILL and NAME statements
for file management. Change test programs to use relative paths
instead of /tmp/ and clean up temp files with KILL. Update .gitignore
for test artifacts.
