title: How to configure a sublime file_regex for *.bas-files
body: <p>I'm trying to configure a Build System for Freebasic files in Sublime Text3 and want to set the file_regex property to handle the error messages</p>
  
  <pre><code>{
  "selector": "source.bas",
  "cmd": ["fbc.exe", "$file"],
  "file_regex": "..."
  }
  </code></pre>
  
  <p>all i have is something like this, but it doesn't work:</p>
  
  <pre><code>"file_regex": "^[A-Za-z0-9\\\/:]*\\(.*)\(([0-9]*)\("
  </code></pre>
  
  <p>i want to parse this error messages:</p>
  
  <pre><code>C:\projekte\privat\freebasic\test.bas(24) error 3: Expected End-of-Line, found ...
  C:\projekte\privat\freebasic\test.bas(25) error 41: Variable not declared, This ....
  C:\projekte\privat\freebasic\test.bas(26) error 9: Expected expression, found ...
  C:\projekte\privat\freebasic\test.bas(27) error 9: Expected expression, found ...
  </code></pre>
  
  <p>to make my question more precise. I have to fumble apart the filename with extension in a first group and the linenumber in the second group.</p>
  
  <p>could you please help me to find the correct file_regex?!</p>
