My long time ago promised tribute to my favorite operating system is finally near to the useful state, and thus I decided to make a pre-release for the members of the board to try it.
It is, as you may guess from the name, the equivalent of FASMW for DOS. In fact, they share the same editor control, since when I designed the editor's core, I had in plan to make it portable to different operating systems, just as the assembler's core. Well, with editor the thing is a bit harder and more things have to be re-done in the OS-dependent interface, but FASMD shows that it's still possible. Its interface part re-uses some pieces of code from my very old "flat editor" project, BTW. FASMD runs in protected mode and uses DPMI 0.9 for this purpose, so if your DOS doesn't support DPMI, you need to use some third-party DPMI server, I can recommend CWSDPMI for this purpose. Since they are based on the same core, the "feel" of both editors is very similar, and they share the most of the keyboard commands. The FASMD has for now persistently enabled some of the editor's options, in future they will be customizable, as in FASMW. Also some of the windows, like opening a file or entering a text to find, are not yet ready in this pre-release, and are replaced with very ordinary substitutes, just to allow you to enter some text for testing. As this program has not yet been throughfully tested, please use it with caution. PS. The editor's core still needed a few corrections and FASMW has also been updated with a new one. All the common editor files that are used by both FASMW and FASMD reside directly in the SOURCE\IDE directory, while system-dependent interfaces are in its subdirs. PS2. No, I don't yet have a plans for FASMX. Attachment removed - FASMD is a part of DOS distribution now. Last edited by Tomasz Grysztar on 19 Dec 2006, 21:27; edited 1 time in total |

The color theme is the same one I've been using in DOS Navigator for years, and it's a slight variation on standard DN's colors (including those for asm highlighting).

Cool Tomasz! Will there be such an alternative for Linux as well??

I noticed a few bugs using this on my DOS machine. First, the characters to the left and right of the time don't get replaced with space (they retain whatever character was there before fasmd started). Next, the file loader doesn't properly terminate the file in memory - if you edit a larger file, quit, then edit a smaller one, you end up with part of the large file added on to the small one. Last and worst, if the get_memory function fails it returns without popping EDI and ESI first; this one made it impossible to compile.

Thanks for testing. All those were a quick fixes, the attachment above is updated.

Works, thanks! I would appreciate, however, if FASMD is able to use the full text-screen. I run DOS (and full-screen DOS-Boxes) usually with 34 text lines, in 640x480 resolution, with a text font size of 14. Just in case: the number of rows-1 can be found in BIOS vars (40h:0084h, type BYTE).

Japheth, does that work in XP? My brief tests failed, so maybe I did it wrong.

@Tomasz: will it be much to do porting it to Linux? if now, I think I've found a new project to work on :p

Well, there's is quite a bit of work, because the whole interface of the editor has to be re-written. If you're still interested
and want some details, please contact me. |

But what did you test? that at 40:0084h is indeed the value for rows-1? That is valid for NTVDM as well. Indeed the NTVDM VGA emulation is not that bad, even the CRT port values are correct. |

I'll have to re-install freeDOS to give her a test go.

About porting to Linux, please select the names carefully, FASMX will be the TTY version or the X Windows version?

Tomasz Grysztar 08 Dec 2006, 14:43
The TTY version would be called FASMT.

I like that name
[edit]And the Win32 console version FASMC? [/edit] |

Added a bit of customizability at source level (search for the "Configuration" in the FASMD.ASM). In future there will be perhaps .INI file like in case of FASMW, for now you can just configure by recompiling (not really a bad thing for a programmer).
For some advanced tweaks: there's a "set_video_mode" routine, which looks like this: Code: set_video_mode: mov ah,0Fh int 10h cmp al,3 je video_mode_ok mov ax,3 int 10h video_mode_ok: ret You can try changing the text mode that FASMD uses by playing with this function. For example add a call to function 1112h of video BIOS interrupt to set 80x50 (with awful 8x8 font), or try the below extension to set the VGA 80x30 mode (I really like this one): Code: set_video_mode: mov ah,0Fh int 10h cmp al,3 je video_mode_ok mov ax,3 int 10h video_mode_ok: ; The code below is taken from the small program that comes with DOS Navigator source distribution (originally in TASM) macro outb v1,v2 { mov al,v1 out dx,al mov al,v2 inc dx out dx,al dec dx } macro outv v { mov al,v out dx,al } cli mov dx,3C4h outb 0,1 mov dx,3D4h outv 23 inc dx in al,dx and al,127 out dx,al dec dx outv 17 inc dx in al,dx and al,127 out dx,al mov dx,3CCh in al,dx or al,192 mov dx,3C2h out dx,al mov dx,3D4h outb 6,11 outb 7,62 outb 9,79 outb 16,234 outb 17,140 outb 18,223 outb 21,231 outb 22,4 outv 17 inc dx in al,dx or al,128 out dx,al dec dx outv 23 inc dx in al,dx or al,128 out dx,al mov dx,3C4h outb 0,3 sti mov byte [fs:84h],29 ; put the right value into 40h:84h retn Last edited by Tomasz Grysztar on 10 Dec 2006, 00:30; edited 1 time in total |
