# x48ng -- HP 48 emulator
|
|
|
|
This is my fork of x48-0.6.4 where I deviate from the original code and do my own thing. (See ./README_0.6.4 for the original README)
|
|
|
|
## Usage
|
|
|
|
`x48ng --help`
|
|
|
|
You can use the script `setup-x48ng-home.sh` or simply run `x48ng --rom=<romfilename>`
|
|
|
|
## Screenshots
|
|
|
|
### `--tui-small` version (ncurses, 4 pixels per character)
|
|
|
|
|
|
|
|
### `--tui-tiny --mono` version (ncurses, 8 pixels per character)
|
|
|
|
|
|
|
|
### `--tui` version (ncurses)
|
|
|
|
|
|
|
|
### `--x11` version
|
|
|
|
|
|
|
|
### `--sdl`/`--sdl2` version
|
|
|
|
|
|
|
|
### manual setup
|
|
|
|
1. Create `$XDG_CONFIG_HOME/x48ng` (usually `~/.config/x48ng/`)
|
|
2. Copy `/usr/share/x48ng/ROMs/gxrom-r` (or any other rom) to `$XDG_CONFIG_HOME/x48ng/rom`
|
|
3. Run `x48ng --print-config > $XDG_CONFIG_HOME/x48ng/config.lua`
|
|
4. Run `x48ng`
|
|
|
|
### Ncurses UI (`--tui`)
|
|
|
|
I had to be a bit 'creative' mapping keys there:
|
|
- `Enter`: `F1`
|
|
- `Left Shift`: `F2` or `PgUp` or `[`
|
|
- `Right Shift`: `F3` or `PgDn` or `]`
|
|
- `Alpha`: `F4` or `Ins` or `;`
|
|
- `On`: `F5` or `Esc` or `Home` or `\`
|
|
|
|
_To quit `x48ng` use `F7`
|
|
|
|
## What have I done:
|
|
|
|
0. renamed it to x48ng to avoid confusion
|
|
1. merged in a SDL1 version I found @ https://code.google.com/archive/p/x48-sdl/source/default/source
|
|
2. removed the code supporting Solaris, HP-UX, etc.
|
|
3. removed the autotools-based build system and wrote a simple Makefile instead
|
|
4. added a x48ng.desktop file and an icon
|
|
5. refactoring as a way to explore/understand the codebase
|
|
6. drop Xresources
|
|
7. link to lua to use it as a config file reader
|
|
8. ported the SDL1 GUI to SDL2
|
|
|
|
## Bugs to fix
|
|
|
|
See and report at https://github.com/gwenhael-le-moine/x48ng/issues
|
|
|
|
## What more I would like to do:
|
|
|
|
### long(er) term
|
|
|
|
- GUI in gtk(4)?
|
|
- support the HP49g ROM?
|
|
|
|
## Compilation
|
|
|
|
The `Makefile` will try to autodetect if necessary dependencies for x11 and sdl front-ends are met and enable/disable x11 and sdl front-ends accordingly.
|
|
|
|
You can force disable x11 front-end by compiling with `make WITH_X11=no`.
|
|
|
|
You can force disable sdl front-end by compiling with `make WITH_SDL2=no`.
|
|
|
|
Ncurses front-end is always built-in.
|
|
|
|
### Dependencies (see .github/workflows/c-cpp.yml for debian packages names)
|
|
|
|
- Lua
|
|
- readline
|
|
|
|
for SDL2 version:
|
|
|
|
- SDL2
|
|
- SDL2_gfx
|
|
|
|
for x11 version:
|
|
|
|
- x11
|
|
|
|
for Ncurses:
|
|
|
|
- ncursesw
|
|
|
|
## Installation
|
|
|
|
1. Run `sudo make install PREFIX=/usr` (see the Makefile to see what variables your can override.)
|
|
2. once installed run `/usr/share/x48ng/setup-x48ng-home.sh` to setup your ~/.x48ng/. It sets up a HP 48GX with a 128KB card in port 1 and a 4MB card in port 2
|
|
3. run `x48ng` and enjoy
|
|
|
|
## Development
|
|
|
|
- `make FULL_WARNINGS=yes` to compile with all warnings
|
|
- `make clean` and `make mrproper` to clean between compilation runs
|
|
- `make pretty-code` to format the code using `clang-format` and the provided `.clang-format`
|
|
