This allows comic module authors to use the full power of regular
expressions in XPath expression, see http://exslt.org/regexp/regexp.html
for usage. Please be aware that these use the prefix re: instead of
regexp: here.
This is a first step for #42. Since most access to the scraper classes
is through instances, modules can now dynamically override url and name
(name is now a property).
HTML character encoding in the context of HTTP is quite tricky to get
right and honestly, I'm not sure if I did get it right this time. But I
think, the current behaviour matches best what web browsers try to do:
1. Let Requests figure out the content from the HTTP header. This
overrides everything else. We need to "trick" LXML to accept our
decision if the document contains an XML declaration which might
disagree with the HTTP header.
2. If the HTTP headers don't specify any encoding, let LXML guess the
encoding and be done with it.
This basically reverts commit 86b31dc12b.
It now works like this: If the use has pycountry installed, it is used.
If not, Dosage falls back to a small internal list generated from
pycountry by scripts/mklanguages.py.
This means additional work if we ever decide to translate Dosage, since
pycountry already has all the translations for language names...
This fixes#23.
Maintaining the descriptions creates quite a bit of overhead (finding
them, copying them, checking if they are still correct) for a minimal
user benefit.
PS: Viewing this diff should be easier in a difftool that shows changes
in a line, for example kdiff3.
Each comic module author can decide if she wants to use CSS or XPath,
not a mix of both. Using CSS needs the cssselect python module and the
module gets disabled if it is unavailable.
This is modeled parallel to the "adult" feature, except the user can't
override it via the command line. Each comic module can override the
classmethod getDisabledReasons and give the user a reason why this
module is disabled. The user can see the reason in the comic list (-l or
--singlelist) and the comic module refuses to run, showing the same
message.
This is currently used to disable modules that use the _ParserScraper if
the LXML python module is missing.
This reverts commit fcde86e9c0 & some
more. This lets python-requests do all the encoding stuff and leaves
LXML with (hopefully) clean unicode HTML to parse.
- This also makes "<base href>" handling an internal detail of the regular
expression scraper, future scrapers might not need that or handle it in
another way.
