Expected behavior:
$ kmimetypefinder5 example.py
text/x-python3
or
$ kmimetypefinder5 example.py
text/x-python
or
$ kmimetypefinder5 example.py
text/plain
Actual behavior:
$ kmimetypefinder5 example.py
application/xhtml+xml
Summary: Python scripts with a string containing HTML can be
misidentified as HTML files by kmimetypefinder5.
For example, this python script is identified as
"application/xhtml+xml":
#! /usr/bin/env python3
example_string = \
"""\
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>Example title</title>
</head>
<body>
<p>Example body</p>
</body>
</html>
"""
print('Hello, world!')
This difficulty is not shared by other mimetype identification tools.
$ kmimetypefinder5 example.py
application/xhtml+xml
$ cat example2.py #! /usr/bin/env python3
print('Hello, world!')
$ kmimetypefinder5 example2.py
text/x-python3
$ mimetype 'example.py'
example.py: text/x-python
$ mimetype 'example2.py'
example2.py: text/x-python
$ file --mime-type 'example.py'
