| <p>If you are using <a href="http://rvm.beginrescueend.com/"><span class="caps">RVM</span></a> in your machine (just as <a href="/2010/07/28/getting-started-with-rvm.html">Francisco showed us</a> the other day) then you should take advantage of the <a href="http://rvm.beginrescueend.com/workflow/rvmrc/#project">project .rvmrc</a> feature.</p> | ||
| <p>Let’s say your project is in the directory:</p> | ||
| <div class="highlight"><pre><code class="bash">~/repo/myproject | ||
| </code></pre> | ||
| </div><p>And you have ruby-1.8.7 and ruby-1.9.2 in <span class="caps">RVM</span> and you want to use 1.9.2 ruby version in that project.</p> | ||
| <p>Then you can put this in your <code>~/repo/myproject/.rvmrc</code> file:</p> | ||
| <div class="highlight"><pre><code class="bash">rvm 1.9.2 | ||
| </code></pre> | ||
| </div><p>So, every time you change to that project directory, <strong><span class="caps">RVM</span> will change to the specified ruby version</strong>.</p> | ||
| <div class="highlight"><pre><code class="bash"><span class="lineno"> 1</span> chalofa <span class="o">[</span>1.8.7<span class="o">]</span>:~/repo/myproject<span class="nv">$ </span>ruby --version | ||

| </code></pre> | ||
| </div><p>As you can see, first we are using Ruby version 1.8.7, after the change to our project directory, the version selected in the <code>.rvmrc</code> is used: 1.9.2<br /> | ||
| Once you abandon the project directory, your default Ruby version will be used!</p> | ||
| <p>It even <strong>works with gemsets</strong> so you can have something like this in your <code>.rvmrc</code> file:</p> | ||
| <div class="highlight"><pre><code class="bash">rvm 1.9.2@blog | ||
| </code></pre> | ||
| </div><p><strong>And every time you cd into your directory, your ruby version and gemset will be changed :)</strong></p> | ||
| <h2>Final thoughs</h2> | ||
| <p>Whether this file should or shouldn’t be in your project repo is up to you, but <span class="caps">IMO</span> it should be ignored, creating the possibility to be defined by every user…</p> | ||
| <p>What do you think about that?</p> | ||
