WIP : Eff it, I left the magic memcpy in. Printing mostly works but it's still broken. Calls to _cputs and _cputsf may mysteriously fail due to some kind of memory corruption I haven't tracked down yet. This commit leaves in a bunch of commented testing code, the next commit will rip them out.

WIP. Somewhere in between the init of basic_cmd_run and basic_cmd_list calls to _cputs stop working with constant character string pointers and only work with pointers off the heap.

WIP Immediate mode, printing, and listing is working, but something wierd is going on with _cputs. See the comment in basic_cmd_list. I'm tempted to throw the C away and move it all to ASM so I can have more control & awareness of what's going on.

WIP : About to rip out the old parser and solver, can't get things working the way I expect and the old code is in the way

WIP scrolling seems to work correctly now if all you ever do is call advanceCursor()

WIP minor improvements to conio/screen for scrolling, still doesn't work reliably once we print more than 25 lines

WIP. Storing code in line numbers and listing is working. Added a RUN command, and refactored the line runner logic out of basic_repl into basic_run_line. The repl still works but the RUN function is busted. The parser logic is increasingly getting in the way, and the solver is not as useful as I originally thought. The original design of the datastructures and logic is getting in my way and adding confusion. I may need to try something simpler.

WIP : Storing line numbers, detecting immediate mode vs storage mode, solver tests are not working
2024-05-06 17:51:42 -04:00

Added the ability to parse commands as well as expressions.
...
Added basic PRINT and REM commands.
Added solver tests which had been around for a while and not committed.
All execution is still immediate mode.

Refactored the name of some defined basic parser codes and exposed basic_solve_expr for tests
2024-05-06 14:51:04 -04:00

- Added the ability to start a line with a number and store it for later execution
...
- Added the ability to force immediate mode processing (calculator mode) by beginning a line with =
- Expanded parser testing
- Expression execution seems to be broken now, everything is returning error code 0 and not returning results
2024-05-05 06:55:39 -04:00
921a9dd8bd
- Added string strip methods lstrip and rstrip
...
- Fixed the tokenizer to chomp whitespace from left and right of tokens
- Fixed the tokenizer so it returns reserved symbols not just constants and expressions
- Added some tests for the basic tokenizer and parser
- Started working on structures to allow the basic interpreter to store lines in memory
2024-05-04 22:08:20 -04:00
0d1ecd9bd3
- All tests passing
...
- Updated README and image
- Added itoa to stdlib
- Implemented modulus math for bcc which has none in the stdlib
- Updated the build scripts to work on Ubuntu 22
- Added bochsrc with some useful overrides (new bochs bios in ubuntu is broken, use the legacy)
- Made most of stdlib compile and run under GNU C for testing
- Improved the tokenizer so it will return tokens of more than one character
- Moved the basic parser from using void pointers to store values to using basic_value unions to represent possible types
- Added tests for the basic tokenizer
