* Line breaks reinserted
* None in place of ''
* Check for browser before selecting default input format (to fix
KeyError)
* Remove redundant -S option and clarify help to make it slightly more
obvious what output formats make sense
* Added long-form arguments and slightly more sensible names (not really a
fix, but I personally like having them)
This restructures things to better support future implementations of
other input formats. The default formats are specified in a global dict
of browsers, which prevents duplicating the list of choices for browser
in bother get_args() and main(), and a new option enables overriding of
the default.
This allows importer.py to process Netscape HTML exports from Firefox
(and other Mozilla browsers) with three distinct types:
* bookmarks (sans shortcuturl attribute)
* keywords (bookmarks with a shortcuturl attribute)
* searches (keywords with a URL containing a %s substitution)
The first two can be combined at will in either quickmark or bookmark
output formats, the only difference being that keywords will be used in
place of titles when exporting to quickmark format. Searches are
exported to qutebrowser.conf format, or the new config.py format.
Dictionaries are used in the import function for readability's sake, but
the command line arguments follow the same general formula of true-false
flags used to select input bookmark types and the output format.
With the previous commit, we also checked that PyQt was >= 5.7.1, but we want to
support PyQt 5.7.0. Instead, we now check the individual components by hand.
Also, the previous check accidentally allowed PyQt >= 5.2.0 instead of 5.7.0.
With an older PyQt built against a newer Qt, we still don't have its features
available.
This also drops support for exact=True with compiled=True as the semantics for
that are unclear, and it's not used.
