# Recommended preferences in Sublime

Protip: When setting preferences in Sublime text, NEVER use preferences > Settings - Default. When you upgrade Sublime Text, there is a god chance that these will get completely re-written and any changes/customizations you make will get blown away!

Instead, what you want to edit is your preferences > Settings - User. When you first open this file, this most likely will be empty. The following is a good example of some popular settings:

{
// OS X only: This controls if an empty window is created at startup or not.
"create_window_at_startup": false,

// Set to true to ensure the last line of the file ends in a newline
// character when saving
"ensure_newline_at_eof_on_save": true,

// Set your p[referred font size]
"font_size": 15.0,

// If enabled, will highlight any line with a caret
"highlight_line": true,

// Additional spacing at the bottom of each line, in pixels

// OS X only: When files are opened from finder, or by dragging onto the
// dock icon, this controls if a new window is created or not.
"open_files_in_new_window": false,

// remember_open_files makes the application start up with the last set of
// open files. Changing this to false will have no effect if hot_exit is
// true
"remember_open_files": false,
"hot_exit": false,

// Set to true to automatically save files when switching to a different file
// or application
"save_on_focus_lost": true,

// Set to false to disable scrolling past the end of the buffer.
// On OS X, this value is overridden in the platform specific settings, so
// you'll need to place this line in your user settings to override it.
"scroll_past_end": true,

// The number of spaces a tab is considered equal to
"tab_size": 2,

// Set to true to insert spaces when tab is pressed
"translate_tabs_to_spaces": true,

// Set to true to removing trailing white space on save
"trim_trailing_white_space_on_save": true,

// Disables horizontal scrolling if enabled.
// May be set to true, false, or "auto", where it will be disabled for
// source code, and otherwise enabled.
"word_wrap": true,

// List any packages to ignore here. When removing entries from this list,
// a restart may be required if the package contains plugins.
"ignored_packages":
[
"Block Cursor Everywhere",
"Vintage"
]
}


## Avoid trailing commas

Setting preferences in Sublime is editing code. If there is an error with the code, there is a good chance that Sublime will break and break hard.

All the preferences use a "key"; "value" pair syntax. When there is a pair is that is followed by another pair, this requires a trailing comma like so:

{
"key": "string-value",
"key":
[
"value",
"value"   <- NO COMMA!!
],
"boolean": true   <- NO COMMA!!
}


Notice that the last line DOES NOT have a comma.
