Some of you are probably aware, that since I've added the ability to type into ZScript, I've made a few text parsing modules.

Recently, I've given some thought to making a more portable version of my complex debug shell.

The one that I use is rather tightly woven into other things, and it isn't very easy for most people todeduce how it works. Therefore, I started again clean, writing something designed to run a single instruction in a shell, rather than a macro script.

This is now, tested and working. Press F7 to open the debug shell.

If anyone is curious on how to do new, insane things, have a look at this beastie! ;)

 

I designed the code in the link (above) so that when you press the F5 key (you can change this in the CFG settings), ZC opens a shell window. From there, you may type in any of the following commands:

Supported Instructions

 

Syntax and Usage

 

Tokens terminate by either a comma, or reaching the end of the string (NULL character).

If anyone is interested in using this, or if any of you are curious and have questions, please let me know. I may expand it to support multiple instructions and macros in the future, if there is any demand for that.

 

It also does not yet pause the action in ZC. I plan to add some ZScript functions to suspend all of ZC, except for scripts, just as the combo types Freeze All, and Freeze All (except FFCs), as Game->Freeze(int type, bool state), at some future point, so that scripts needn't use messy combo modification (or steal FFCs), in order to pause the game action.

 

The code for this should be both highly legible, and easy to modify.  Adding instructions is relatively simple and straightforward, although you do need to add them in a few places--similar to adding ZASM and ZScript in the ZC Source files pertaining to ZScript (ffscript):

 

To Expand the Instructions

1. Define a case value after:
define LINKITEM = 12; //item, (BOOL), on / off

2. In the switch statement inside of int num_instruction_params(int instr),
add a case value for the new instruction, and return the number of params that it uses.

3. Determine the actual in-use instruction identifier, and create a case set flow/entry for its characters, in
int match_instruction(int token), returning the new case value on a match.

4. In the switch statement inside of void execute(), add the new case label, and give it instructions to call a normal ZScript function.

 

5. Args and Stack Size
The present stack supports up to two args, so, if you need more, you will need to modify the value of
MAX_ARGS. The size of the stack is automatically determined and generated on compilation.

 

 

Script Syntax and Structure

This script makes use of a few new syntax features in ZScript, that require the latest Necromancer alpha builds. These include both typedef instructions, and script-local variables, arrays, and constants.

 

The details on these new mechanical ZScript components are a bit lengthy, so, for the sake of those shy of <tl;dr>, I'll put it all in a spoiler tag...

Using

 

Press F7 to open the shell.
Type an instruction.
Press the DOWN ARROW KEy to ENQUEUE the instruction, or;
    Press ENTER to execute the instruction.
If you have enqueued instructions, press ENTER either at the
    end of an instruction, or on an empty line to EXECUTE
    all of your enqueued instructions.

 

 

Traces
 
You may print a line of text, or a literal value directly
to allegro.log using the following syntax:
 
%s
    This traces all characters that follow it, to
    allegro.log as a string.
    It eats all leading spaces and characters,
    so all of these are identical:
        %sPRINTME
        %s:PRINTME
        %s PRINTME
        %s: PRINTME
        
    The output of this will be:
        LOG: PRINTME
        
%d
    This traces a literal value (integer or float)
    to allegro.log.
    It eats all leading spaces and characters,
    so all of these are identical:
        %100.500
        %s:100.500
        %s 100.500
        %s: 100.500
        
    The output of this will be:
        LOG: 100.500
        
Traces cannot be enqueued at this time.
    

Sequence Scripts
 
You may save a sequence of instructions that you have entered
into the shell into one of TEN SEQUENCE SLOTS.
 
To do this, after entering a series of commands, with a BLANK LINE,
press the CONTROL KEY and one of the main number keys (above the home row,
not on the number pad), 1 through 0.
 
The number key that you press corresponds to the SEQUENCE slot that your
sequence script is using.
 
If you save the quest, your sequence script will save with it.
 
To run a sequence script, open the shell, and do not add any INSTRUCTIONS ON THE STACK:
Type the command: RunSequence,id
 
    [example--
 
        RunSequence,1
        
    --end example]
    
    This will immediate;y run Sequence Script 1.

FFC and Additional Visual and Audio Commands

 

 

In version 1.11, I added the ability to enqueue a series of commands at one time.

 

Press the down arrow key to enqueue an instruction!
