如何让“sout”速记在 Sublime Text 3 中工作？

Question

I am trying to get the "sout" shorthand to work in Sublime Text 3 for Java. In vscode and other editors typing "sout + [tab]" will fill in "System.out.println". When I try this in Sublime Text it instead prints "southPane".

This is something that can be done via a snippet or a completion ; both can do this but which you use depends largely on the complexity of the text you want to insert and how many you have.

The main difference is that a snippet is a XML based format where each file contains a single completion whereas a sublime-completions file is JSON formatted file that can contain many completions at once. Additionally, all snippets are automatically added to the command palette and made available only in files to which they apply.

Thus the XML based snippet is good for larger stretches of code (eg blocks) or for any text that needs to contain characters that would be a pain to encode as JSON, whereas the JSON based completions are favored for shorter sequences of text, since you can pack more of them into a file.

To demonstrate a snippet, use Tools > Developer > New Snippet to generate a stub, then replace the stub with this content and save it as a file in the default offered location (your User package) as a sublime-snippet file; the name doesn't matter, but the extension does:

<snippet>
    <content><![CDATA[
System.out.println($0);
]]></content>
    <tabTrigger>sout</tabTrigger>
    <scope>source.java</scope>
</snippet>

This says that in a Java file the abbreviation sout Tab will expand out to the text System.out.println(); with the cursor left inside the parenthesis.

Alternately, create a file with the following content and save it in your User package as a sublime-completions file (name doesn't matter, only extension, and you can use Preferences > Browse Packages to find the User package`:

{
    "scope": "source.java",

    "completions": [
        { "trigger": "sout", "contents": "System.out.println($0);" },
    ]
}

This does the same as the above example, but the file is smaller, and you can include multiple items in it, say for example by also adding:

        { "trigger": "serr", "contents": "System.err.println($0);" },
