Very much not needed, yeah, much like most of the development tools. Now, debug tools...

I've found it pretty easy and discoverable how to mirror a random LSL2 pic in PE.

So the code to flip the vector image is there already, but hidden... and there's an off by one bug that is fixed in Experimental?

Hmmm...

It is not a feature in SCI Companion and frankly the picture editor's code scares me so I don't think I'd want to try and add it.

I did just mirror a random pic from Larry 2 using Sierra's own picture editor though. It was pretty easy, just a few clicks. Would you like a copy?

If the save/load scripts don't have path separators in any of their strings, they're not affected by what I fixed.

Smells like the latter possibility, then 🤔

For whatever reason, main.sc does not have the line (include sci.sh) in it, or it is including a version of sci.sh that for whatever reason is missing all these define statements.

SCI Syntax Help / Re: Converting sciAudio to Sierra Script

« on: June 23, 2020, 01:21:12 PM »

It's not SCI I don't think that's confused by the backslash. If I decompile this test script with "sciAudio\\command.con" in it, I get "sciAudio\mmand.con" in the disassembly and syntax tree alike. I'll look into the string parser and report back.

Okay I think I found it. In ParserCommon.h:

Code: [Select]

default:
    if (isxdigit((uint8_t)ch))
    {
        chHex = charToI(ch);
        lookingForSecondHex = true;
    }
    else
    {
        str += "\\"; // Add it, the following char was not an escape char
        processCharNormally = true; // Add the current char too
    }That last line is what mucks it up. Commenting that out seems to help the co part survive without apparently being mistaken for an invalid hex sequence and eaten. A new build will be is available from the stash in my signature shortly now.

The recently-added fixes for QFG1V got me to update SCI Companion.

Code: [Select]

- (and (<= `a evtMsg) (<= evtMsg `z))
+ ;EO: For some reason, `a and `A compile exactly the same,
+ ;despite the different cases.
+ ;This makes inputting a proper name (e.g. Eric)
+ ;impossible without the keys.sh defines.
+ (and (<= KEY_a evtMsg) (<= evtMsg KEY_z))
This is because indeed the part of the compiler that works out backtic sequences uppercases what follows. This should now be fixed. There's a build that should leave the case alone in the stash linked in my signature.

That'd be "not an object".

What exactly isn't an object, I don't know. E_NOT_OBJECT may be raised by the Clone, DisposeClone, and RespondsTo kernel calls. More likely, it may also be raised by trying to send to something that's not an object, such as a null variable.

(Going off of SCI11 here, just in case.)

unless two scripts have cross dependencies

Main and ColorInit come to mind.

They contain names and exports and such, so the compiler can link smarter than Sierra's did. I don't think they're actually needed for present purposes.
