MCAmiga 0.5 68000

Posted by ALB42 on 27. Mai 2020No Comments

Due to multiple questions, yes it is possible to compile MCAmiga for 68000 as well, even it would still need AmigaOS3.x to work. But because I got some requests also to supply such a binary a made a separate archive for a Version for 68000, it’s not really tests, at least it starts:

But no promises about the function. It is rather slow but somehow usable.

MCAmiga 0.5

Posted by ALB42 on 27. Mai 2020No Comments

Finished a little bit more MCAmiga testing, especially on MorphOS and AmigaOS4 there where some serious problems. On AmigaOS4 the device view did not work at all, just crashed, reason was a bug in the AmigaDOS unit of FreePascal. I fixed that exact problem already for other platforms, and now also on AmigaOS4. On MorphOS only tiny changes are needed, mostly related to the supplied lha being a little bit different than the one on classic, but still very close. AROS was a bigger problem, the lha command here is completely different, very limited actually, for example you cannot extract a single file.

MCAmiga 0.5 on MorphOS 3.11

I got a hint from Charlie to use cad to unpack archives, because it supports many different formats and it’s available for at least classic and MorphOS, I found out for AROS there is also a version in contrib, that means at least Icaros even comes automatically with it. AmigaOS4 seems not to have it, at least I did not find it. It works very nicely, easy to operate, but sadly it’s only for unpacking archives, no way to pack them. That means the functionality is limited to read only access in MCAmiga. Therefore I gave xad a lower priority over the native lha/lzx programs, except on AROS because there xad is the better choice, the native lha command does not work at all.

Besides that big feature for handling archives, I added a lot of small stuff, like Shift cursor keys to select file, or Ctrl cursor keys to jump fast up and down or to first item (left) or to last item (right). Start programs with enter and wait for finish or with Shift Enter an do not wait for it, so effectively start it in a new shell.

The Source is now also available on GitHub completely. I did put it there on the first release but I forget to push the changed source. I committed locally only. But now the full source should be there, so take it an improve it and most importantly have fun with it.

MCAmiga 0.5 on Amiga OS 4

For now that is already a very useful program for me, more or less finished. I do not really need more than that, maybe one day one could add an editor to it, especially an hex editor. But at the moment I don’t need it.

The requirements did not change, still Amiga 68020+, 4 MB, AmigaOS3.x, AmigaOS4 (except X5000), MorphOS 3.x, AROS i386 ABIv0, AROS ARM ABIv0, AROS x64 ABIv1 NonSMP

MCAmiga & LHA Archives

Posted by ALB42 on 22. Mai 20202 Comments

Working on the lha handling inside MCAmiga, would be nice to have it like in Midnight commander where you can directly browse inside archive, add, remove files, and even edit files inside.

I got it somehow to work, still with some limitations, for example, LHA you cant create an empty directory, so I create the directory with a ‘delete_me’ file inside. Also when the directory is created “merged” on adding (usually means added together with its parent directory) you cant remove it, if will stay there, even empty. But still it works already very nicely. Until now you can copy files to archive, copy file from archive, make a new directory, rename files. View and edit files (also with external tools, file is extracted to temp dir). Also introduced the Tools menu (F2) well known from midnight commander.

I did not try on AROS/MorphOS or so until now, hmm curious if all LHA versions are the same, I should try some different versions 😉

MCAmiga 4 colors

Thanks to some hints/wishes in amiga.org forum I spend some time to optimize the use of MCAmiga on lowest possible setting, thats means a high res, no interlace screen with 4 colors, like starting without startup-sequence. It works quite nicely, one still can see activated entries, so it’s somehow usable, but of course on a real Amiga will be quite slow.

MCAmiga 0.4

Posted by ALB42 on 15. Mai 20203 Comments

Worked a little bit on the mouse control for MCAmiga, the mouse/video unit combination makes it very easy, exactly the same mechanisms than the keyboard events. So now you can also use the mouse to click on buttons or select files. The search and jump function was already included in the last version but I did not show them in a video, so I included them here.

The second part was to activate app window functionality, that you can drag and drop a file onto one of the two panels and the program will automatically jump to that directory and file. I did give me some headache though, because initially it did not work on Classic Amiga and MorphOS, and I found out that the FreePascal workbench unit had a big bug. The syscall offset of the needed Function AddAppWindowA was wrong. Now thats fixed as well.

MCAmiga 0.2

MCAmiga work continues, move now completely works (also with the fast move when source and destination are on the same harddisk). I build in a little text viewer also with hex display which I use very often, and for editor you can define yourself which editor you want to use, ed, editpad or what else you like. Already works very nicely and I use it frequently now, and hopefully that motivates me to improve it further. 😉

MCAmiga 0.2

There where some little changes needed to make it compile for other Amiga Systems (AROS, MorphOS, AmigaOS4) but not serious changes, but I did not try them, so be careful when using it.

  • Amiga 68k: 3.x+, 68020 or AROS m68k
  • AROS: i386 ABIv0, ARM ABIv0, x86_64 Non-SMP
  • MorphOS: 3.x
  • AmigaOS4: 4.x (except X5000)

More playing with video unit

Posted by ALB42 on 8. Mai 20202 Comments

Continuing playing with the video unit, learn how to resize the window, something I did not implement in the vidcrt unit in freepascal. The commander style application already is kind of usable for basic stuff. Copy, Delete, Rename, basic movement, selecting such stuff (move is not implemented until now and a lot of error checking is missing, especially overwriting :-P)

I took a lot of work to get the resize stuff working, especially if an additional window like the help is open at this moment, but finally that is working well.

If you want to play with it (68konly atm) you can download the exe of MCAmiga, but be warned it’s just a playground for me, so bugs may occur a lot, and do some harm to your files.

Playing around with FreePascals Video unit

Posted by ALB42 on 2. Mai 2020No Comments

Playing around with the video unit, really easy to write a norton/midnight commander style application with it. Not really seriously plan to make such app, but to be fair, Amiga is lacking a good norton/midnight commander style app which is fully controllable via keyboard (typical amiga application are more mouse centered, like dopus 4/5, filemaster and so on)

Amiga 1.x Online Compiler

Posted by ALB42 on 10. April 2020No Comments

Charlie implemented a Amiga 1.x compatible version of the FreePascal compiler. It’s a little bit harder to write program for 1.x so many features are missing in Workbench 1.x. These machines are usually 7 Mhz and only very little RAM, so cross compiling is highly advised. Of course the Online compiler would be a good starting point for basic tests.

And that is exactly what I did, I created a separate Online Compiler for the Amiga 1.x Version, why separate, because most of the sources of the original Online Amiga FreePascal Compiler will not work with 1.x. I included a creation of a bootable ADF file directly from the executable created so you can directly try your work inside a UAE instance for example in the very nice Scripted Amiga Emulator.

See for yourself:

So if you are locked inside your home because of corona, why not do something new and start to learn to code FreePascal for Amiga. Have fun.
