Added DOI regex function to utils.py which is called in add_cmd.py
upon specifying a new DOI. DOI validation applies directly on
argument parsing by using a custom argparse.Action.
Additionally, reverted FakeSystemExit subclassing Exception, but added
an explicit __init__ so that we can emulate the SystemExit.code
functionality without having to change the superclass.
Unittest just checks that both `pubs` and `pubs --help` raise a
`SystemExit` exception with error code 0. Due to how argparse
handles the `--help` keyword, this is the best way I could think to
provide test coverage without heavily modifying the parser structure
or the unittest infrastructure.
To ensure the `pubs` matches the behavior of `pubs --help`, it now
raises the same `SystemExit(0)` exception via `sys.exit(0)`. And
in order to catch it in the unittest, I had to modify the
`FakeSystemExit` behavior slightly.
Made subparsers not required in the main parser, but if no commands are parsed,
then the parser prints its help. When a command is present, the normal
functionality preserved.
Removed the single unittest that checks for this exact behavior.
For now, the editor_input and edit_file functions do not make sense
outside of the context of an ui. Having them in the content module
was confusing. (See issue fixed by a600855.)
Replace the in-house stubbing by the facilities offered
by pyfakefs for running tests. We don't use `io.open`
anymore, because pyfakefs does not stub it correctly.
We rely on a patched version of pyfakefs, as a few bug
remain in the official repo.
The implementation is designed to be robust to filesystems having integers
or nanosecond stat time.
Added a requirements.txt file for the tests:
`pip install -r tests/requirements.txt` to install the necessary packages
to run the tests.
Fix#13, Fix#14
1. Removed the unicode wrapper around fake_env io
2. Overrided pyfakefs cStringIO with StringIO (Python 2.x)
3. copy_dir will copy file in binary file to the fake filesystem
*unless* they are bib, yaml, txt or md files
4. ui.handle_exception() conserve traceback
Numerous unicode subtelties required diving into pyfakefs and configobj
source code. Unicode on Python 2.x is the worst.
