Allow for an optional argument to only delete cached entries from
a specific module.
delete all cache entries
$ gallery-dl --clear-cache
or
$ gallery-dl --clear-cache all
only delete entries for instagram
$ gallery-dl --clear-cache instagram
This allows for stuff like "{extractor.url}" and "{extractor.category}"
in logging format strings.
Accessing 'extractor' and 'job' in any way will return "None" if those
fields aren't defined, i.e. in general logging messages.
Instead of a strict list of (URL, RESULTS)-tuples, extractor result
tests can now be a single (URL, RESULTS)-tuple, if it's just one test,
and "only matching" tests can now be a simple string.
The functionality of --(chapter-)filter and --(chapter-)range are now
also exposed as the following config-file options:
- extractor.*.image-filter
- extractor.*.image-range
- extractor.*.chapter-filter
- extractor.*.chapter-range
TODO: update configuration.rst
Useful for quick testing (even though -g and -j kind of do the same)
and to fill a download archive without actually downloading the files.
-s does the same as the default behaviour, except downloading stuff.
Maybe it should get a more fitting name, as it does actually write to
disk (cache, archive)?
Standard logging to stderr, logfiles, and unsupported URL files (which
are now handled through the logging module) can now be configured by
setting their respective option keys (log, logfile, unsupportedfile)
to a dict and specifying the following options;
- format:
format string for logging messages
available keys: see [1]
default: "[{name}][{levelname}] {message}"
- format-date:
format string for {asctime} fields in logging messages
available keys: see [2]
default: "%Y-%m-%d %H:%M:%S"
- level:
the lowercase levelname until which the logger should activate;
available levels are debug, info, warning, error, exception
default: "info"
- path:
path of the file to be written to
- mode:
'mode' argument when opening the specified file
can be either "w" to truncate the file or "a" to append to it (see [3])
If 'output.log', '.logfile', or '.unsupportedfile' is a string, it will
be interpreted, as it has been, as the filepath
(or as format string for .log)

Python3.5 and lower throw an UnicodeEncodeError when trying to print
not-encodable characters when not using 'utf-8' as encoding.
Setting their error handlers to 'replace' should help.
Instead of a dictionary/object, input file options are now specified
by a 'key=value' pair starting with '-' for options only applying to
the next URL or '-G' for Global options applying to all following URLs.
See the docstring of parse_inputfile() for details.
Example option specifiers:
- filename = "{id}.{extension}"
- extractor.pixiv.user.directory = ["Pixiv Users", "{user[id]}"]
-spaces="are_optional"
-G keywords = {"global": "option"}
- see docstring of parse_inputfile() for details
- TODO: unittests, recursion (currently setting for example
{"extractor": {"key": "value"}} will override the whole "extractor"
branch instead of merging {"key": "value"} into the already existing
dictionary)
- requests and urllib3 version on 1 line
- close input file after reading from it
- use expand_path for unsupported-urls file
- remove unnecessary logging from options.py
The same filter infrastructure that can be applied to image URLS now
also works for manga chapters and other delegated URLs.
TODO: actually provide any metadata (currently supported is only
deviantart and imagefap).
This allows for image filtering via Python expressions by the same
metadata that is also used to build filenames (--list-keywords).
The usually shunned eval() function is used to evaluate
filter-expressions, but it seemed quite appropriate in this case and
shouldn't introduce any new security issues, as any attacker that could do
> gallery-dl --filter "delete-everything()" ...
could as well do
> python -c "delete-everything()"
The output can be configured via the 'output.progress'
config value.
Possible values:
- true: Show the default progress indicator
"[{current}/{total}] {url}" (default)
- false: Never show the progress indicator
- <string>: Show the progress indicator using this
as a custom format string(1).
Possible replacement keys are:
- current: current URL index
- total : total number of URLs
- url : current URL

- speed improvements, especially in the 'interpolate' function
- 'interpolate' now prioritizes base-level values if they exist
- "username" is chosen before "extractor.<category>.username"
- -u/--username & co can now override config-file values
