I was trying to close unused files in Eclipse and accidentally made something wrong. Now I can’t see syntax highlighting for one of my files.
Here are two screenshots – on the first you can see file, where highlighting is broken, and on the second everything is fine:
Highlighting doesn’t work for this file only. Extension of this file is correct. I tried to look through all menu buttons carefully, but this attempt failed, I suppose Eclipse is hard enough for newbie. Of course, I tried to find information in the Web, but couldn’t get anything relative.
I guess you accidentally opened the file with the ‘Text Editor’. Refer screenshot below.
