Sublime Text .gitignore template

The editor splits its state across two files and the distinction matters. A .sublime-project file holds the folders in the project, the build systems and the project scoped settings, which are all things a team might reasonably share. A .sublime-workspace file holds the session: open tabs, unsaved buffer contents, find history and cursor positions. This template ignores both, so if you want to share a project definition, remove that one line.

sftp-config.json is the rule that matters most. The popular upload package stores its configuration in that file, in the project root, and the configuration includes the host, the username and, by default, the password or the path to a private key. It is a plain text credential sitting in a file that looks like editor configuration, which is exactly the kind of thing that gets committed without a second glance.

sftp-config-alt*.json covers the alternative configurations of the same package. If either file has ever been committed, the credential is in the history of every clone and needs rotating, not just removing. That is the shape of every secret in git: an ignore rule stops the next commit and does nothing about the ones already made, so the fix always ends with changing the password.

The Package Control rules cover the package manager's caches and certificate bundles: the last run marker, the certificate authority lists, the merged and user bundles and the cache directory. Together they are the largest group in this template and the least interesting, since none of it is project specific.

The cache rules for *.tmlanguage.cache, *.tmPreferences.cache, *.stTheme.cache and bh_unicode_properties.cache cover compiled syntax definitions, preferences and theme data. GitHub.sublime-settings holds settings for an integration package, which can include an access token depending on how it was configured. None of the cache files are project specific, so they are pure noise in a diff and are rebuilt the first time the editor opens a file that needs them.
