Where does sublime store themes?
In st3 you can override packages by creating a same-name folder under ~/Library/Application\ Support/Sublime\ Text\ 3/Packages/
For example, if you want to override the default theme:
Open contents of Sublime Text.app (right clic > show package content), locate Contents/MacOS/Packages/Theme - Default.sublime-package
.sublime-package files are zip, so copy the file somewhere outside, unzip it, locate the Default.sublime-theme file. It's json.
Do your edits to the file
Navigate to ~/Library/Application\ Support/Sublime\ Text\ 3/Packages/, create a 'Theme - Default' folder
Copy your Default.sublime-theme into the folder you just created
Done. Any edits you'll do to Default.sublime-theme will be auto-loaded in your current theme, no need to restart ST.
For reference:
https://www.sublimetext.com/docs/3/packages.html
Sublime Text 3 packages installed via Package Control are by default stored as .sublime-package
zip files in your Packages
directory, whose location depends on your operating system:
- Linux:
~/.config/sublime-text-3/Packages
- OS X:
~/Library/Application Support/Sublime Text 3/Packages
- Windows Regular Install:
C:\Users\YourUserName\AppData\Roaming\Sublime Text 3\Packages
- Windows Portable Install:
InstallationFolder\Sublime Text 3\Data\Packages
The easiest way to edit them is to install PackageResourceViewer
from Package Control. Once installed, open the Command Palette with ⌘ShiftP (OS X) or CtrlShiftP (Windows/Linux) and type in prv
to access the PackageResourceViewer options.
Select Extract Package
, then scroll down to Theme - itg.flat
and hit Enter. This will extract the package into your Packages
folder, which can be easily accessed via your operating system's file manager (Finder, Windows Explorer, Nautilus, etc.) by selecting Sublime Text → Preferences → Browse Packages…
(this is for OS X, Windows and Linux have a separate Preferences
menu). Any edits to the files in this directory will override the files contained in the Installed Packages/Theme - itg.flat.sublime-package
file.
If you only wish to edit a single file, after typing prv
into the Command Palette, chose PackageResourceViewer: Open Resource
instead. You can then navigate through your packages and choose the file(s) you wish to edit - Theme - itg.flat/itg.flat.dark.sublime-theme
, for example. Once you edit the file(s) you have chosen, they will be saved in the Packages
directory,
However, please keep in mind that if the package is updated in the future, the changes will not apply because you've overridden them by extracting the files into Packages
. This is not quite the case if you choose Open Resource
- only the files you chose to edit and save will be stored in Packages
, and they will override the identically-named file in the .sublime-package
archive. If the package is updated in the future, the file(s) containing your edits will still override the same file(s) in the archive, but the rest of the files will be updated. For example, if you edit itg.flat.dark.sublime-theme
via Open Resource
, when the entire Theme - itg.flat
is updated, your customized file will override the file of the same name in the package archive, but all other files will have the changes from the update applied.
