CodeLab v6.12 for Paint.NET 5.0.12 (Updated February 11, 2024)

[toe_head2001]

That's pretty strange. CodeLab should only fallback to the Verdana font if none of the other fonts (Consolas, Courier New, ect.) are available.

Given that Consolas, Courier New, and Verdana are all included with Windows 7, those fonts must have been uninstalled from your computer at some point.

CodeLab 4.2 Released

This is only for Paint.NET 4.1.6+!

 

Big update today...

 

Changes:

▪ New Icons! (toe_head2001)

▪ Improved the 'unsaved changes' dialog for when there's only one tab open, and also changed the wording in the dialog when there's multiple tabs open, to be less confusing (toe_head2001)

▪ The search box (in Find & Replace) now turns red when there are no matches (toe_head2001)

▪ When using Save As, the "//Name: " comment is now parsed to try to create a default filename. If it's unsuccessful, it will fall back to "MyScript.cs" (toe_head2001)

▪ Minor fixes to Format Document (toe_head2001)

▪ Files (with .cs extension) can now be dropped (drag and drop) into CodeLab to open them. (toe_head2001)

▪ Options to use force SingleRenderCall and Legacy ROI when Building DLL (toe_head2001 and BoltBait)

▪ Added three additional menu items to the Effects menu to start CodeLab with specific parameters (EffectsFlags, EffectRendingSchedule). (toe_head2001)

▪ Scripts with "//Submenu: Adjustments" will be put in the Adjustments menu instead of the Effects menu (BoltBait)

▪ If your effect has a sample image for The Plugin Browser, it will be shown on the Build to DLL form (BoltBait)

▪ Added a new high res icon for when CodeLab is running higher than 96dpi (BoltBait)

▪ Added new build options (Legacy ROI, Single Render Call) to File New template screen (BoltBait)

▪ Added the following script comments to control build options: (BoltBait)
// Force Legacy ROI
// Force Single Render Call

▪ CodeLab can now be installed to the Store version of Paint.NET. However, when running the Store version you can not create a Visual Studio project from your CodeLab script. Building a DLL still works fine. (toe_head2001 and BoltBait)

▪ Assortment of bugfixes, cleanups, refactorings (toe_head2001 and BoltBait)

When developing a CodeLab script that utilizes special rendering commands, CodeLab now has the ability to run under those conditions while you are developing your script:

 

There are some new options on the File New screen:

 

Here are the new features of the Save as DLL screen:

 

You can now install CodeLab when using the Microsoft Store version of Paint.NET.  The only limitation is that you can't generate a Visual Studio solution of your CodeLab script.  If you click the button, nothing bad happens, it just tells you of the limitation.

 

New Options:

 

Legacy ROI... Here is a good description of how the ROI's work:

https://forums.getpaint.net/topic/113917-effectoptions/?do=findComment&comment=555790

 

Single Threaded vs. Single Render Call...

SingleThreaded only uses 1 thread to make calls into Render. It'll still be called many, many times, just like if you didn't use the flag, but without any multithreading. Progress bar still works here.

SingleRenderCall only calls Render once, and it's done with 1 array with all of the roi's. That this is effectively SingleThreaded is just a corollary. You won't see any progress bar updating here because the progress bar is updated as each Render call finishes, and there's no side-channel for reporting progress.

New Icons! (toe_head2001) 

 

I didn't get around to adding larger icons for HiDPI, but I plan to do so in the near future.

Thanks for your hard work.
Is there any chance to Format Document and Find/Replace icons to be added to the toolbar?

Easy.  Do you really use it that often?

Hmmm... not as easy.  We would need to highlight the icon if the Find window is open and close the window if clicked again...

Would we though? Most programs don't do that with their find buttons.

Yes, I use it very often. But I think I could get used to the CTRL + Q combination.

 

Now, CodeLab became very confuse for me. What version I need to use?

 

[BoltBait]

Normally, you would just start CodeLab using the top entry, "CodeLab...".  However,

If I run older scripts in Single Render Call or Legacy ROI mode, CodeLab freezes and I'm forced to close Paint.Net from Task Manager.

 

Edit:

Sorry, there was something wrong with my script.
CodeLab works perfectly.

You'll need to give us more information.  I'm not seeing any lockups.  I am able to run older scripts in all 4 of the CodeLab modes.

 

EDIT:  How old is "older"?  I mean, you can't run scripts designed for CodeLab 1.0... but, more modern previous versions (CodeLab 2.0+) should be fine.

If your script is causing CodeLab to freeze, that's an issue.

Can you share the script with us, so we can investigate?

Well, of course it does--you've created an endless loop.

Here's a little sneak peek of what I'm working on.

Disclaimer: It's half broken, and a work-in-progress.

Yellow for Methods

Aquamarine for Structs

Purple for certain Keywords

Light Blue for Parameters and Local Variables

Oooh! I like it!

Is it possible in CodeLab to have more validation conditions?

The way the readonlyproperty system is designed, no.  Sorry, this is not possible.

OK, thanks for the answer.

Wrong alignment for braces when I try to format document because the statement is in line with 'if' keyword.

While there are some fixes for both quick format and for typing, this is not fixed.

 

You can even see it with the default script:

 

The line after:

if (IsCancelRequested) return;

becomes indented improperly after pressing Ctrl+Q for Quick reformat.

Well, that embarrassing. Like, did I even do basic testing?!

For testing of Format Document, I have a special file filled with weird syntax. I've added a single-line if statement to that test file.

I'm pretty sure this was a regression that happened within the last 6 months, because I did test the default script in the past. Anyways, it's in the test file now, so no more regressions in the future.
