Bugs due to two selectors used that are not available on older Mac OS X versions (e.g. 10.8) about context-free HOT 10 CLOSED

I will use the deprecated methods instead in the next release.

That would be great. Download it from here.

Thanks. Appreciate you being open to supporting older systems.

Happy to test a pre-release build if that's helpful.

Thanks for pre-release build to test. Currently taking a look at it.

I've managed to successfully generate an animation which is good, thanks.

There appears to be a couple of issues I encountered, one of which is:

• Opening the "File" menu now generates an uncaught exception error (it didn't previously):

-[GView validateMenuItem:]: unrecognized selector sent to instance 0x7fd98bb9ad60

• I think it's due to this code:

Other issues I've encountered (unrelated to original issue, aside from being encountered now that animation is possible):

• Animation player controller appears to have second & third controls overlapping:

• The "Current Playback Position" field in the middle isn't updated to zero when animation is regenerated (see above value of 1.0 when player head is at 0). (FWIW--particularly with this bug--but even in general--IMO it's not entirely obvious the middle value is the current playback position.)

from context-free.

Also:

• Render > Animate... followed by Render > Animate a frame... doesn't display the selected rendered frame unless you run Render > Save Output... in-between. (Seems like the "render frame" method may not hide the "animation sheet"?)

from context-free.

I'm slightly confused about behaviour which I thought was a bug but appears to be the same in the previous release:

• What is the intended purpose of the Render > Repeat Render menu item?

I had thought that repeating the render used the same seed/variation value again without increment but that doesn't seem to be the case.

Further investigation suggests the effect is related to editing of the list of rules:

1. Create New file. (Variation value is prefixed with "next variation")
2. Paste this: (Prefix: "next variation")

startshape START

shape START {
SQUARE []
}

3. Render > Render (Prefix changes to: "this variation"; seed does not increment)
4. Render > Repeat Render (Prefix is unchanged "this variation"; seed does increment.)
5. Render > Render (Prefix is unchanged "this variation"; seed does increment.)
6. Insert space at on startshape line. (Prefix changes to: "next variation"; seed does not increment)
7. Render > Repeat Render (Prefix changes to: "this variation"; seed does not increment)
8. Render > Repeat Render (Prefix is unchanged "this variation"; seed does increment.)

So, it seems currently "Repeat Render" only "repeats" the render with the same seed if the grammar has also been edited, otherwise it increments the seed and renders as "Render" does.

I think the assumption is that "Repeat Render" is only used on an edited grammar? Which makes sense on one level but also leads to inconsistent behaviour if (for whatever reason--I can't remember why I encountered this originally) "Repeat Render" is used...repeatedly. :) )

I would suggest "Repeat Render" never increments the seed as this behaviour seems more consistent and to me clearly differentiates between the two menu items.

[Thanks again for the test build to try, I look forward to playing more with the animation functionality.]

I have updated the dmg to fix your issues.

1. File menu crash: I fixed CFDGDocument to call GView validateUserInterfaceItem: instead of the now missing GView validateMenuItem: method. Interestingly, this crash does not happen on High Sierra even though the selector is not present in GView.

2. I don't know what is going on with the rewind button. It draws fine on Sierra/High Sierra. I can reproduce the issue by booting into Lion. It doesn't seem to affect functionality.

3. The playback position field resets to 0.0 like it should and now stands out more.

4. Animate-a-frame displays the frame even after a movie was playing

5. Repeat Render was added to make it easier to explore variations when using Render with dimensions. It allows you to sequentially see what variations of a design look like when rendered to a specific size without tediously bringing up the Render with dimensions modal sheet and clicking OK.

I think a better approach would be to get rid if it and get rid of the modal Render with dimensions sheet. Instead, the Render button should have a Render with dimensions mode and the render size controls should be available in a non-modal manner.

Would you mind testing the Context Free 3.1 release candidate on OS X 10.7? I have lost my Lion boot setup and it costs $20 to make a new one. The link is https://www.contextfreeart.org/download/ContextFree3.1.dmg

Never mind, I found my Lion boot disk and tried it out. CF 3.1 runs fine on Mountain Lion and later but would require a lot of work to run on Lion.
