<p>Thanks to <a href="http://web.archive.org/web/20060303052933/http://thread.gmane.org/gmane.editors.textmate.general/8520">a helpful thread</a> on the TextMate mailing list I have the beginning of a solution to insert text at 2 (or more) locations in a file.</p>
|
||
|
||
|
||
<p>I implemented this for a new snippet I was working on for migrations, <code>rename_column</code>. Since the command is the same in self.up and self.down simply doing a reverse search for <code>rename_column</code> in my <a href="http://web.archive.org/web/20060303052933/http://sami.samhuri.net/articles/2006/02/21/textmate-move-selection-to-self-down">hackish macro</a> didn’t return the cursor the desired location.</p><p>That’s enough introduction, here’s the program to do the insertion:</p>

<div class="typocode"><pre><code class="typocode_ruby "><span class="comment">#!/usr/bin/env ruby</span>

<p>Save this as a command in your Rails, or <a href="http://web.archive.org/web/20060303052933/http://blog.inquirylabs.com/">syncPeople on Rails</a>, bundle. The command options should be as follows:</p>
|
||
|
||
|
||
<ul>
|
||
<li><strong>Save:</strong> Nothing</li>
|
||
<li><strong>Input:</strong> Selected Text or Nothing</li>
|
||
<li><strong>Output:</strong> Insert as Snippet</li>
|
||
<li><strong>Activation:</strong> Whatever you want, I’m going to use a macro described below and leave this empty</li>
|
||
<li><strong>Scope Selector:</strong> source.ruby.rails</li>
|
||
</ul>
|
||
|
||
|
||
<p>The first modification it needs is to get the lines to insert as command line arguments so we can use it for other snippets. Secondly, regardless of the <strong>Re-indent pasted text</strong> setting the text returned is indented incorrectly.</p>
|
||
|
||
|
||
The macro I’m thinking of to invoke this is tab-triggered and will simply:
|
||
<ul>
|
||
<li>Select word (<tt><strong>⌃W</strong></tt>)</li>
|
||
<li>Delete (<tt><strong>⌫</strong></tt>)</li>
|
||
<li>Select to end of file (<tt><strong>⇧⌘↓</strong></tt>)</li>
|
||
<li>Run command “Put in self.down”</li>
|
||
</ul>
