amiga-debug Visual Studio Code Extension (fork with libraries support)

This fork is based on the marvellous vscode-amiga-debug extension vscode-amiga-debug by Bartman^Abyss, which is also available on github.

Additional features

  • Standard Amiga libraries are available (you need to specify a Workbench floppy disk or hard disk; see below).
  • MUI is also included on the compilation side (SDK v3.9) and on the execution side (libraries v3.8).
  • clib2 (stdlib, stdio, amigalib, etc.) is available as a set of static libs (please see https://github.com/jyoberle/clib2 for all details).
  • Custom libraries can be declared through the setting of assigns.
  • The bsdsocket.library of UAE can also be enabled.
  • Additional commands to be added at the end of the startup-sequence can be specified.

Quick-start

  1. Install the extension from the Visual Studio Code Marketplace
  2. Create a new empty project folder with File > Open Folder...
  3. From the command palette Ctrl+Shift+P select Amiga: Init Project With Libs
  4. Open .vscode/launch.json and make "kickstart" point to your Kickstart 3.1 ROM and "workbench" to your Workbench 3.1 floppy (.adf)
  5. Hit F5 to build and run a minimal sample project (you should see the MUI app of the above screenshot)
  6. You'll also find on youtube a video showing the previous steps.

How-to-use

  • In .vscode/launch.json, you can also make "workbench" point to a hard file (.hdf) containing the Workbench 3.1; in this case, for WinUAE, you need to specify at the end of its path its number of sectors, number of surfaces, number of reserved blocks, and block size (e.g. "workbench": "C:/Path to hard file/A1200.hdf,32,1,2,512") as they appear in the settings window of WinUAE (see picture below). For FS-UAE, just specify the path to the .hdf file (e.g. "workbench": "C:/Path to hard file/A1200.hdf").
  • Both for WinUAE and FS-UAE, you can also make "workbench" point to a directory virtual hard disk (e.g. "workbench": "C:/Path to directory virtual hard disk/A1200_dir").
  • Still in .vscode/launch.json, you can specify with "assigns" a list of assigns (separated by commas) which will be translated in the startup-sequence; for example "assigns":"MUI: DH2:MUI,LIBS: DH2:LIBS DH2:MUI/Libs" will add at the end of the startup-sequence:
    assign MUI: DH2:MUI
    assign LIBS: DH2:LIBS DH2:MUI/Libs
    The purpose is to add the ability to declare your own libraries residing on your hard file or directory virtual hard disk. These latest are defined as DH2: (DH0: is a directory virtual hard drive, used for booting and where the startup-sequence is located, and DH1: is the directory virtual hard drive containing your compiled program). Thus, the content of DH2: is never modified.
  • "bsdSocket" can be set to true (e.g. "bsdSocket":true) to enable the bsdsocket.library of UAE.
  • At last, with "cmdList", you can specify a list of commands (separated by commas) which will be added at the end of the startup-sequence, e.g. "cmdList":"df0:System/rexxmast".

Please note that if your Workbench disk doesn't have a Fonts directory, you'll have to create one (you can keep it empty), because the startup-sequence is assigning FONT: to it (it seems that some versions of the Workbench disk don't come with a Fonts directory).

UAE_HardFile

Supported Amiga Models

  • Possible values of "config" in .vscode/launch.json:
    • "A500": KS 1.3, ECS Agnus, 0.5MB Chip + 0.5MB Slow; needs Kickstart 1.3 ROM in "kickstart"
    • "A1200": 68020, 2MB Chip; needs Kickstart 3.1 ROM in "kickstart"
    • "A1200-FAST": A1200 with 4MB fast memory
    • "A1200-030": A1200 with Blizzard 1230-IV and 32MB board memory. Requires the absolute path to the Blizzard ROM in "cpuboard".
    • "A3000": A3000 (no profiler support); needs Kickstart 2.0 ROM in "kickstart"
    • "A4000": 68030, 68882, 2MB Chip, 8MB FAST; needs Kickstart 3.1 ROM in "kickstart"
  • Also, you can override the memory configuration using following fields (values are case-insensitive):
    • "chipmem": allowed values: "256k", "512k", "1m", "1.5m" or "2m"
    • "fastmem": allowed values: "0", "64k", "128k", "256k", "512k", "1m", "2m", "4m", "8m"
    • "slowmem": allowed values: "0", "512k", "1m", "1.8m"

How-to-use clib2?

You can do a minimal test of clib2 by setting OPTION_TEST_CLIB to 1 in main.c (created by following the steps in the Quick-start section), and then press F5

If you want to use the clib2 libraries in your own project, your code will have to follow the skeleton of the main.c file.

It is also mandatory:

  • To declare the static libs in your Makefile:
    a. static_libs := -lc -lm -ldebug -lnet -lunix -lc -lm -lamiga, to use Amiga style paths, or
    b. static_libs := -lm -ldebug -lnet -lunix -lc -lm -lamiga, to use UNIX style paths (e.g. "/RAM/myfile" instead of "RAM:myfile")
  • To call SetPatch in your startup-sequence
  • To increase the stack size, especially if you use libunix (see line below)
  • To mount the PIPE: device if you intend to use pipe functions (popen, pclose, etc.); this is done in .vscode/launch.json file through the instruction "cmdList":"C:Mount PIPE:,C:stack 16384,C:SetPatch QUIET" (which also increases the stack size)
  • To have the bsdsocket.library installed in your system (it is required by libnet); this is done in .vscode/launch.json file through the instruction "bsdSocket":true
  • To have at least the usergroup.library installed in your system (it is required by libnet for the usergroup functions); vscode-amiga-debug version 1.7.5 comes with the usergroup.library embedded in DH0:Libs
  • To have AmiTCP installed in your system if you want to take full advantage of the usergroup functions (like setuid, setgroups, etc.)
  • To NOT use libnet functions and native bsdsocket.library functions together, as they are incompatible; in order to avoid this, do not include "<inline/bsdsocket.h>" in your code if your intention is to use libnet

Please be also aware of the current limitations of clib2:

  • libm881 has not been tested and is provided as-is
  • The function hstrerror is currently crashing the program when used
  • ARexx functions GetRexxVar and SetRexxVar are not yet working in the current version of libamiga
  • Neither 64 bits integers nor long double are supported
  • The following functions are currently do-nothing: feclearexcept, fegetenv, fegetexceptflag, fegetround, feholdexcept, feraiseexcept, fesetenv, fesetexceptflag, fetestexcept, fetestround, feupdateenv

You'll find some examples on how to use the clib2 functions in https://github.com/jyoberle/clib2.

How does this fork work?

  • This fork has the MUI libraries included in the disk DH0: which is already used by the original vscode-amiga-debug extension to store the startup-sequence and to boot the Amiga.
  • It adds the needed definitions to the UAE configuration file to declare your "workbench" pointing to a floppy, a hard file or a directory virtual hard disk, and to enable optionally the bsdsocket.library.
  • It also adds the following instructions to the startup-sequence (when "workbench" points to a hard file or a directory virtual hard disk; for a floppy disk, just replace DH2: by DF0:):
    DH2:C/assign C: DH2:C
    C:assign SYS: DH2:
    C:assign S: DH2:S
    C:assign LIBS: DH2:LIBS DH0:MUI/Libs DH0:Libs
    C:assign DEVS: DH2:Devs
    C:assign FONTS: DH2:Fonts
    C:assign L: DH2:L
    C:MakeDir RAM:T RAM:Clipboards RAM:ENV RAM:ENV/Sys
    C:assign T: RAM:T
    C:assign CLIPS: RAM:Clipboards
    C:assign ENV: RAM:ENV
    C:assign LOCALE: DH2:Locale dh0:MUI/Locale
    C:assign PRINTERS: DEVS:Printers
  • At last, when you define "assigns", it adds your assigns at the end of the startup-sequence (see above for an example). And in case you define additional commands with "cmdList", they are also added at the end of the startup-sequence.
