[OS X TeX] color theme from prefs

Hi Herb,

That’s what I did concerning the theme from prefs. I know how to transfer the theme I have been tinkering with, so not a big thing.

As for opacity, that’s what I assumed, but I don’t see any difference. E.g., GLG-Lite seems to have Opacity=0 for the console, yet that is not apparent in the image attached. I am guessing that I miss a more important part of the big picture — e.g., what it means to show the background behind the window. Or there is a system-wide setting that blocks transparency. But these are unlikely because the theme “TransparentTheme” actually does show the background (windows behind).. Interestingly, in that theme all Opacity settings equal 1 — except for Image Copy, whatever that is.

I don’t know whether it has to do with the “Alpha” field (last column, to the right of “Text" and “Background”). I didn’t really understand what that was. Dick’s notes talk about “alpha=1”, while the preference panel have an `entry’ Alpha that is a color. I am starting to believe that Dick’s notes alpha is what I — following the pop-up window, perhaps `color well’ — called “Opacity.” In any case, in TransparentTheme these Alphas are black, but they are also in DarkTheme, where I don’t notice any transparency. 

Having said all this, it is not an important topic for me. I was looking actually for a way to soften a particular hue that I had come across and liked, as I found doing that manually to be difficult, but transparency/opacity is not the way to go.

Based on a previous message from Herb — and Dick’s change notes — I created a theme from prefs, but in doing so the theme (the colors) did not change — as if the preferences had already been overwritten with the loaded theme. In particular, I got the LiteTheme, which had been loaded by default. Later I created a new theme (say, NT), and when I tried the experiment again, the theme that got created from prefs was identical to NT, which was loaded at the time.

Or, perhaps more likely, some local settings are such that TexShop looks at the “wrong” preferences?


I haven't done this in a while now. The Theme doesn't change the old values in Preferences that were created by an old version of TeXShop so that data should still be there.

After pressing the button to create a new Theme from the old Preferences make sure to give it a name and Save it. Then you need to change the Theme for whichever mode you wish to use it (Dark or Light Mode) to use that names Theme.

As I said above, the settings that you had in your TeXShop.plist file should still be there. You can't simply replace TeXShop.plist with a new one because the OS actually copies it to memory and you new one will be overwritten with the one in memory.

One of the nice things about the use of Theme files is that they are easy to get at (they are sored in ~/Library/TeXShop/Themes) and can be freely moved from one system to another.

Opacity is the opposite of Transparency so it's a measure of how much of the background behind the window shows through.

Hope this was helpful.

Good Luck,
