崇高的文字3摘要变量（来自先前的分配）

Question

I recently try to adjust to sublime text 3 instead of netbeans which I was using for web development for the last years, I really liked the features in netbeans IDE especially the code templates which is the equivalent to sublime snippets, unfortunately I wasn't able to find the variable from last assignment like in netbeans code templates.

this is code template I am using in netbeans

error_reporting(E_ALL);
ini_set('display_errors', '1');
echo '<pre style="background: black;color: white; font-size:16px; font-wheight:bold; direction:ltr!important;text-align: left;">';
print_r(${VARIABLE variableFromPreviousAssignment default="$variable"});
echo '</pre>';
die();

this is the snippet I am using in sublime text 3

<snippet>
    <content><![CDATA[
error_reporting(E_ALL);
ini_set('display_errors', '1');
echo '<pre>';
echo print_r(${1:*});
echo '</pre>';
]]></content>
    <!-- Optional: Set a tabTrigger to define how to trigger the snippet -->
    <tabTrigger>dbg</tabTrigger>
    <!-- Optional: Set a scope to limit where the snippet will trigger -->
    <scope>source.php</scope>
    <description>dbug snippet</description>
</snippet>

In simple words what I am looking for is the equivelent in sublime to this in netbeans

(${VARIABLE variableFromPreviousAssignment default="$variable"}

Answer 1

I changed your snippet to the text you had in the Netbeans shortcut:

<snippet>
    <content><![CDATA[
error_reporting(E_ALL);
ini_set('display_errors', '1');
echo '<pre style="background:black; color:white; font-size:16px; font-weight:bold; direction:ltr!important; text-align:left;">';
print_r(${1:\$variable});
echo '</pre>';
die();
]]></content>
    <tabTrigger>dbg</tabTrigger>
    <scope>source.php</scope>
    <description>dbug snippet</description>
</snippet>

In a PHP document in Sublime, type dbg and hit Tab , and the following will appear:

^{syntax highlighting is Neon}

$variable is highlighted, allowing you to replace it with something of your own choosing.

For more information on snippets, check out the snippet reference .

Unfortunately, there is no way in Sublime to save the value of the last assignment just using a snippet - you'll need a plugin for that. Let me know if that's a feature you really need, and I'll see if I can put something together.

Forget about ugly print_r code, use dBug library.

1. Download http://dbug.ospinto.com/ and include in your project

2. Add the following function in your project:

    /** * Returns dBug object [pretty object/array] * @param $var * @param bool $stop */ function dbug($var,$stop=FALSE) { if ( ! class_exists('dbug') ) { require '../path_to/dbug.php'; } new dBug($var); if ( $stop ) die(); } 

   1. Enjoy ;-)

Answer 3

On menu bar open Preferences -> Key Bindings :

Now add below code on right-side of Key Bindings within square bracket []

{ 
    "keys": ["ctrl+shift+c"],
    "command": "insert_snippet",
    "args": { "contents": "echo \"<pre>\";\nprint_r(${0:\\$variable_to_debug});\necho \"</pre>\";\ndie();\n" }
}

Enjoy your ctrl+shift+c shortcut as a Pretty Print of PHP.
