Creating Context File

EMperson

The process for creating context files is unclear to me. I've read the sklanguser.pdf summary, but I'm confused on a few things:

1) How to set up the Directory Structure. If I want to create the context file "HelloWorld.cxt", where should the file "HelloWorld.il" go?

2) I keep getting the error "can't access startup.il". Where should that file be stored? What should the contents of startup.il be?

I just need a super concise, easy tutorial of how to create a context file. Thanks!!

    I agree, the documentation makes it sound difficult.

    This is a simple way of doing it:

    In a DOS shell, cd to your Skill folder

    Run Allegro Skill by typing:

    il_allegro

    Name your context file:

    setContext("My_context")

    load your Skill file(s) needed to run the code (normally only one):

    load("mySkillFile.il"); This is what startup.il does - you would add a load statement for each Skill file.

    define the initiation process:

    defInitProc("My_context", 'myFunction); Where myFunction is the name of the procedure/function that you want to call in your Skill file.

    Protect your code:

    sstatus(writeProtect t)

    saveContext("My_context.cxt")

    Thanks, this is super helpful! One last thing-- I need to load my code into Allegro PCB Designer, and my code has a command I created using  axlCmdRegister. So how do I load my "My_Context.cxt" file into Allegro, and then run a command?

    Where you previously would have used "load", use "loadContext".

    Be aware that 17.2 context files are in a 64bit folder.

    Run your command the same way as before.

    I read somewhere that axlCmdRegister() cannot be included in a context file... How do I still use commands?

    I always register commands in the allegro.ilinit file - not the Skill file itself unless I'm debugging.

    Do you have to create your own .ilinit file? Where should the allegro.init file be? I read a different post that says to check where the ALLEGRO_ SITE variable but I don't know where that is...

    Would you mind posting how to find the allegro.iliinit file, as well as example code of registering commands in the allegro.ilinit file? Thanks Slight smile

    The allegro.ilinit file resides in your Skill path.

    Type "set" on the Allegro command line to get the settings of all your variables. Find allegro_site. The skill folder is a subdirectory of that folder.

    Here's an example:

    loadContext("AutosilkUtils_public.cxt")
    axlCmdRegister("silkutils_public" 'ASU_start ?cmdType "interactive")
