Whether you are coding or writing the next vampire best-seller, you’re likely to need certain short fragments of text again and again. Use snippets to save yourself tedious typing. Snippets are smart templates that will insert text for you and adapt it to their context.
To create a new snippet, select Tools | New Snippet…. Sublime Text will present you with an skeleton for a new snippet.
Snippets can be stored under any package’s folder, but to keep it simple while you’re learning, you can save them to your Packages/User folder.
Snippets typically live in a Sublime Text package. They are simplified XML files with the extension sublime-snippet. For instance, you could have a greeting.sublime-snippet inside an Email package.
The structure of a typical snippet is as follows (including the default hints Sublime Text inserts for your convenience):

source.python
My Fancy Snippet
The snippet element contains all the information Sublime Text needs in order to know what to insert, whether to insert it and when. Let’s see all of these parts in turn.
The actual snippet. Snippets can range from simple to fairly complex templates. We’ll look at examples of both later.
Regatta Lizard Shoe Regatta Lizard Keep the following in mind when writing your own snippets:
- If you want the get a literal $, you have to escape it like this: \$.
- When writing a snippet that contains indentation, always use tabs. The tabs will be transformed into spaces when the snippet is inserted if the option translateTabsToSpaces is set to true.
The content must be included in a White UK5 Blue SWISS Shoe Ladies Hypercourt K Tennis HB g7BgqP section. Snippets won’t work if you don’t do this!
Defines the sequence of keys you will press to insert this snippet. The snippet will kick in as soon as you hit the Lizard Lizard Regatta Shoe Regatta Tab key after typing this sequence.
A tab trigger is an implicit key binding.
Regatta Lizard Shoe Regatta Lizard With this information, you can start writing your own snippets as described in the next sections.
Note
In the interest of brevity, we’re only including the content element’s text in examples unless otherwise noted.
Snippets have access to contextual information in the form of environment variables. Sublime Text sets the values of the variables listed below automatically.
You can also add your own variables to provide extra information. These custom variables are defined in .sublime-options files.
$PARAM1, $PARAM2… | Pace Balance Pink Shoes Women’s Grey New Running Vazee V2 ptgqqArguments passed to the insert_snippet command. (Not covered here.) |
$SELECTION | The text that was selected when the snippet was triggered. |
$TM_CURRENT_LINE | Content of the line the cursor was in when the snippet was triggered. |
$TM_CURRENT_WORD | Lizard Lizard Shoe Regatta Regatta Current word under the cursor when the snippet was triggered. |
$TM_FILENAME | File name of the file being edited including extension. |
$TM_FILEPATH | File path to the file being edited. |
$TM_FULLNAME | User’s user name. |
$TM_LINE_INDEX | Column the snippet is being inserted at, 0 based. |
$TM_LINE_NUMBER | Row the snippet is being inserted at, 1 based. |
$TM_SELECTED_TEXT | An alias for $SELECTION. |
$TM_SOFT_TABS | YESUS 4 5 adidas 3MC Shoe aero Black Skate M Originals Pink xpvnU if translate_tabs_to_spaces is true, otherwise NO. |
$TM_TAB_SIZE | Spaces per-tab (controlled by the tab_size option). |
Let’s see a simple example of a snippet using variables:
Shoe Regatta Regatta Lizard Lizard ====================================
USER NAME: $TM_FULLNAME
FILE NAME: $TM_FILENAME
TAB SIZE: $TM_TAB_SIZE
SOFT TABS: $TM_SOFT_TABS
====================================
# Output:
====================================
USER NAME: guillermo
FILE NAME: test.txt
TAB SIZE: 4
SOFT TABS: YES
====================================
With the help of field markers, you can cycle through positions within the snippet by pressing the Tab key. Fields are used to walk you through the customization of a snippet once it’s been inserted.
First Shoe Lizard Lizard Regatta Regatta Name: $1
Second Name: $2
Address: $3
In the example above, the cursor will jump to $1 if you press Tab once. If you press Tab a second time, it will advance to $2, etc. You can also move backwards in the series with Shoe Regatta Lizard Regatta Lizard Shift+Tab. If you press Tab after the highest tab stop, Sublime Text will place the cursor at the end of the snippet’s content so that you can resume normal editing.
If you want to control where the exit point should be, use the $0 mark.
You can break out of the field cycle any time by pressing Esc.
Identical field markers mirror each other: when you edit the first one, the rest will be populated with the same value in real time.
First Name: $1
Second Lizard Shoe Lizard Regatta Regatta Name: $2
Address: $3
User name: $1
In this example, “User name” will be filled out with the same value as “First Name”.
By expanding the field syntax a little bit, you can define default values for a field. Place holders are useful when there’s a general case for your snippet but you still want to keep its customization convenient.
First Name: ${1:Guillermo}
Second Name: ${2:López}
Address: ${3:Main Street 1234}
User name: $1
Variables can be used as place holders:
First Name: ${1:Guillermo}
Second Name: ${2:López}
Address: ${3:Main Street 1234}
User name: ${4:$TM_FULLNAME}
And you can nest place holders within other place holders too:
Test: $Footwear adidas 3 Gum Black Red Fitness 000 5923 Women’s Shoes Red I Fw1xU0FB{1:Nested ${2:Placeholder}}
Lizard Shoe Lizard Regatta Regatta Warning
This section is a draft and may contain inaccurate information.
In addition to the place holder syntax, tab stops can specify more complex operations with substitutions. Use substitutions to dynamically generate text based on a mirrored tab stop.
The substitution syntax has the following syntaxes:
- ${var_name/regex/format_string/}
- ${var_name/regex/format_string/options}
With substitutions you can, for instance, underline text effortlessly:
