dm42decode - a command-line decoder tool
I have been enjoying both the Plus42 Emulator and a DM42 calculator, and while I can convert programs from binary to text using them, I thought it would be nice to have a command-line tool that could also do the job.
I've written one, and I've made it available under a GPL license. You can get a copy of the source code here: dm42decode I develop on Linux, and in that environment the tool can be simply built via typing "make". Disclaimer: The tool may not be 100% perfect, but it is able to correctly decode the various raw files that I've found on the web at: 42progs. If folks try it and find any bugs, please let me know. |

RE: dm42decode - a command-line decoder tool
Too bad you don't have a version for Windows.
I myself developed an interface tool for DM41L, DM41X then another one for DM15L and yet another one for DM11L These tools allow me to exchange programs between emulators and calculators (see my site http://clones.phweb.me) I started working on the DM32 and I put aside the DM42 interface (for 2024...) because it was much more complex. My tools are in Excel in order to try to be as portable as possible. Are you considering a version for Windows? http://ti58c.phweb.me http://clones.phweb.me http://www.instagram.com/ti58c "No!

Pierre, I am very impressed by your emulator page. You have put in a lot of work! I bookmarked yur emulator website and will be spending more time looking at its contents.

I bookmarked yur emulator website and will be spending more time looking at its contents.Hi Namir, MERCI !!! (You have the habit of complimenting me and I am very flattered.) The last improvement to my ti58c emulator dates back to April 19, 2023. I let myself be tempted to add new instructions largely inspired by calculators... HP! Then I wrote the documentation for Miroslav Nemecek's ET-57 calculator (largely improved clone of the TI-57). For the moment I'm mainly working on code interfaces between calculators and emulators. For example, my first program converts HP41cx sources into dump code for DM41X or PX41CX (Alex Garza prototype) but also produces barcodes for HP41C from programs from emulators. My second program compiles/decompiles HP15C programs for exchange between emulators and DM15L. The third program concerns the HP11C... Since I retired I haven't stopped and I will continue ! I wish you Happy Holidays for this end of the year. http://ti58c.phweb.me http://clones.phweb.me http://www.instagram.com/ti58c "No! Do or Do not. There is no try!" [Master Yoda] |

You might have a look at: (Free42) txt2raw - raw2txt These programs are based on the sources of Free42 and use some functions for the translation. Therefore you can expect to get the same results. I haven't tried but it should also compile on Windows. After all Free42 does. |

Quote:You might have a look at: (Free42) txt2raw - raw2txt Thanks but I know the solutions you cite but: - raw2txt not very "flexible" (I wrote a parameterized command file for ease) - txt2raw inoperative (.pl!!!) Otherwise : - dm42coder.py requires the installation of python but does not work with the python3 that I use. - hp41uc with win41uc gives good results with programs that are not too specific HP-41 and there remains Swissmicros Programming tool... so I have to follow my intuition and develop my own interface... after finishing hp-11C (dm11L) then hp-32s (dm32)! http://ti58c.phweb.me http://clones.phweb.me http://www.instagram.com/ti58c "No!

Instead of reinventing the wheel, these C programs use the same code for the transformations as Free42. They are just thin wrappers around the necessary function calls. I haven't tried it yet, but the same should work with Plus42. |

I guess I can't really follow you there. I wasn't able to remove the dependency on the GUI so easily. My approach would probably be to extract these methods into separate files so they can be used by both the GUI and CLI. Asked somewhat bluntly: Would it be possible to make these two tools available with a regular release of Free42/Plus42? Most of the members in this forum are probably not able to compile them themselves. Therefore, they would be happy if these were made available officially. (12-26-2023 12:28 PM)Thomas Klemm Wrote: I haven't tried it yet, but the same should work with Plus42. In the meantime I tried to compile the two programs with plus42desktop. That worked, but when I let them run it results in a segmentation fault. I haven't looked at it in detail yet, but I saw that the signature of core_init changed: free42: Code: void core_init(int read_state, int4 version, const char *state_file_name, int offset); plus42desktop: Code: void core_init(int *rows, int *cols, int read_state, const char *state_file_name); This can not work of course but should be easy to fix. |

RE: dm42decode - a command-line decoder tool
I added txt2raw and raw2txt targets for the Linux version.
I'll add targets for the Windows and MacOS versions in a bit. |

RE: dm42decode - a command-line decoder tool
That's great to hear.
And we even got a decent usage. Usage: ./txt2raw <text-file> Usage: ./raw2txt <raw-file> I 'd say on the scale of evolution of the wheel we're right between a "wooden wheel rimmed with iron" and a "rubber tire and an inner tube mounted on a good rim with good shock absorbers".

RE: dm42decode - a command-line decoder tool
I added the targets for Windows, but I still need to do some testing and look at some build warnings. I'll try to add the MacOS targets tomorrow.
Once it's all done, I'll upload executables to my web site. They won't be part of the app distribution since they only need to be updated when there are additions to the instruction set. |
