Is there a way to delete custom functions (e.g. extractZipCode in the screenshot below) from the QGIS Field Calculator without having to look into the expressions folder on disc?

I know I can simply delete the Python script in this folder:

C:\Users\admin\.qgis2\python\expressions

But is there a way to actually do it from within QGIS?

    Would be nice if they added a Delete file button next to New file. But if you want to do it within QGIS then I guess you could use the Python Console: import os; os.remove('C:/Users/admin/.qgis2/python/expressions/example.py') – Joseph Mar 22 '17 at 11:27

One way which I found to do that is to erase the definition of the function from the Function Editor tab and you won't see the function name under the 'Custom' functions list .

  • You mean just erasing the entire content? Or removing the name (New File), which is created on the left-hand side in the Function Editor? In the latter case, how would you do that? Right-clicking does not seem to work... – BritishSteel Mar 28 '17 at 10:47
  • By erasing the definition I meant to erase the contents of the file. The latter functionality is not yet available in QGIS. – nash Mar 28 '17 at 14:47
