Crash on Mac OSX Yosemite when opening the Font Chooser

[BrunoEssmann]

Dear DiffMerge Team

I recently switched to Mac OSX Yosemite and noticed that I cannot change the fonts (e.g. Menu > Preferences > File Window > Window Font > Choose...) the application crashes. I've attached the crash log.
The behavior was observed with DiffMerge "4.2.0 (697:52f98c4fcb) [intel] stable" on OSX Yosemite "10.10 (14A389)".

Cheers,
// Bruno

PS: I've got an older machine lying around somewhere that runs OSX Lion (10.7) and there the font selector works, so there's probably been some change in the api.

[Beth]

Does it behave differently if you are logging in with a different user account?

I don't think testing has happened yet with Yosemite. I'll get this logged.

I'm having the same issue on Yosemite. I was hoping there was a work around so that I could increase the size of the font to something usable.

[BrunoEssmann]

It does happen when logged in with a different user account.
Also, I've tried running DiffMerge in Low Resolution mode to no avail.

My current solution as a workaround is to use a copied prefs file from another machine.

Is there any documentation available on the contents of the prefs file:
~/Library/Preferences/SourceGear DiffMerge Preferences

I'm having the same issue on Yosemite. Any feedback from the devs would be appreciated; for now, I'll just stick to the FileMerge that comes packaged with Xcode.

I was also unable to select fonts under Yosemite. After I copied the preferences file from an older installation on Mavericks, DiffMerge no longer crashes when trying to open the font chooser, but it brings up the debug alert which can be seen in the attached file. Hope this helps pinpoint the root cause. Looking forward to the new version that will fix this.

I'm also unable to change the DiffMerge 4.2 font size on Mac OS X 10.10.2.

Same problem here.

@Beth: What is the prognosis for getting this resolved in the near future, given that it was reported several months ago?

[Beth]

I don't have a timeline for a fix on the font chooser yet, but I do have a way to change the fonts.

Close DiffMerge.

Open a Terminal window and enter this:

Code: Select all

open -e "$HOME/Library/Preferences/SourceGear DiffMerge Preferences"

This will open the file in TextEdit. The font setting is under the [File] section.

[wrightmikea]

I tried

Code: Select all

open -e "$HOME/Library/Preferences/SourceGear DiffMerge Preferences"

but there is no [File] section, but even if I added one, what is the syntax used to specify the font name and size?

I also have a working DiffMerge 4.2.0 on a Mavericks OS X installation, where I can change the font size using the Preferences dialog (without it crashing). I cannot find where these preferences are stored on Mavericks. The open command responds with a message saying that the file does not exist.

So, can someone upload the contents of a preferences file that shows the non-default font?

Can someone reply with the location of this file on Mavericks?

[Beth]

Under [File] try adding your font in a format like Font=11:76:consolas or maybe Font=10:70:Copperplate.

The location of the file is the same for any Mac OS. I just checked Lion and the location of the preferences file was the same as on Yosemite.

[ron.stewart]

@Beth: Thanks for the follow-up. Can you clarify what the "11:76" and "10:70" attributes in your examples specify? And do font faces with spaces in their names (e.g., Source Code Pro or Input Mono) need quoting or escaping to be used?

[Beth]

The first number is the font size. That and the name are all you need to change. The other number can be left as is.

[zorz]

i added the Font=11:76:consolas in the mentioned file but nothing changed. the font remains the default courier font size 10.

Any idea how to fix this?

[danomatic]

I just ran up against this same issue and essentially DiffMerge is unusable on my Macbook Pro as I can't make the font larger. I don't see any preferences folder located at ~/Library/Preferences/SourceGear. I do see a preferences file at ~/Library/Preferences/com.sourcegear.DiffMerge.plist but it seems to be in XML format so the changes to add a font size herein don't seem to match up with the format in this file. Any other suggestions? Thanks.
