[jira] [Comment Edited] (TIKA-2194) matlab files detected as
'text/plain'
[ https://issues.apache.org/jira/browse/TIKA-2194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15820902#comment-15820902 ]

Ah, I've found the problem with your filename case. In the tika mimetype definition for matlab we have this:
{noformat}
<!-- <glob pattern="*.m"/> - conflicts with text/x-objcsrc -->
{noformat}
This leaves us with a problem - matlab program files don't have any universal unique magic to spot, and they don't have a unique file extension either :(
That said, with your test file and the Tika App, we do manage to detect it correct as matlab just from the function definition on the first line. If you change your line 73 to {{def sherlock = new DefaultDetector();}} then the detection will work
