Changelog¶

1.2.3 (2023-02-02)¶

now using typehints, tested on Python back to 3.6; though could work with older Python 3 versions. See the new docs for better information on types (#70)
fixed problem with usage of warn=True; in a for loop, an internal variable warning_thrown wasn’t being reset after each loop iteration, with the result that all objects returned after a warning was thrown were None regardless of the actual result. sorry about that! (#112) (#113)

Fixed class WorksContainer to work with cursor output of works results (e.g., cr.works(query, cursor=”*”)) (#106) thanks @IvanSterligov

fixes to docs/contributing.rst and package level docs for habanero (#89) (#90) thanks @Daniel-Mietchen !
fix limit and offset internal handling for request and Request (#91) thanks @Bubblbu !
content_negotation throws warning now on 4xx/5xx status code to allow for bad DOIs alongside good DOIS (#92)
add example to README for querying works by DOI (#93)
fail better when json is not returned; try json.loads and catch ValueError (JSONDecodeError is a subclass of ValueError) (#97)
funders, journals, members, prefixes, types and works gain warn parameter to optionally throw a warning instead of error if a DOI is not found - not found DOI with warn=True returns None (#69)

Crossref() class gains ua_string option to add an additional string to the user-agent sent with every request (#84)

filter_names() and filter_details() altered to get metadata for works, members and funders filters; and added egs to members and funders methods for using filters (#67)
many typos fixed (#80) thanks @Radcliffe !
use of a progress bar is now possible when fetching works route data, only when doing deep paging, see progress_bar parameter (#77) (#82)
content_negotiation fixes: ids parameter is now required (has no default), and must be a str or list of str (#83)
no longer testing under Python 2

changelog was missing from the pypi distribution, fixed now (#71)
fixed Crossref.registration_agency() method, borked it up on a previous change (#72)
set encoding on response text for content_negotiation() method to UTF-8 to fix encoding issues (#73)
fix Crossref.filter_names() method; no sort on dict_keys (#76)

Added verification and docs for additional Crossref search filters (#62)
Big improvement to docs on readthedocs (#59)
Added mailto support (#68) (#63) and related added docs about polite pool (#66)
Added support for select parameter (#65)
Added all new /works route filters, and simplified filter option handling within library (#60)

Now using vcrpy to mock all unit tests (#54)
Can now set your own base URL for content negotation (#37)
Some field queries with works() were failing, but now seem to be working, likely due to fixes in Crossref API (#53)
style input to content_negotiation was fixed (#57) (#58) thanks @talbertc-usgs
Fix to content_negotiation when inputting a DOI as a unicode string (#56)

Added more documentation for field queries, describing available fields that support field queries, and how to do field queries (#50)
sample parameter maximum value is 100 - has been for a while, but wasn’t updated in Crossref docs (#44)
Updated docs that facet parameter can be a string query in addition to a boolean (#49)
Documented new 10,000 max value for /works requests - that is, for the offset parameter - if you need more results than that use cursor (see https://github.com/CrossRef/rest-api-doc/blob/master/rest_api.md#deep-paging-with-cursors) (#47)
Added to docs a bit about rate limiting, their current values, that they can change, and how to show them in verbose curl responses (#45)
Now using https://doi.org for cn.content_negotation - and function gains new parameter url to specify different base URLs for content negotiation (#36)
Fixes to kwargs and fix docs for what can be passed to kwargs (#41)
Duplicated names passed to filter were not working - fixed now (#48)
Raise proper HTTP errors when appropriate for cn.content_negotiation thanks @jmaupetit (#55)

fixed problem with cr.works() where DOIs passed weren’t making the correct API request to Crossref (#40)
added support for field queries to all methods that support /works (<https://github.com/CrossRef/rest-api-doc/blob/master/rest_api.md#field-queries>) (#38)

user-agent strings now passed in every http request to Crossref, including a X-USER-AGENT header in case the User-Agent string is lost (#33)
added a disclaimer to docs about what is actually searched when searching the Crossref API - that is, only what is returned in the API, so no full text or abstracts are searched (#32)
improved http error parsing - now passes on the hopefully meaningful error messages from the Crossref API (#31)
more tests added (#30)
habanero now supports cursor for deep paging. note that cursor only works with requests to the /works route (#18)

Fix wheel file to be a universal to install on python2 and python3 (#25)
Added method csl_styles to get CSL styles for use in content negotiation (#27)
More documentation for content negotiation (#26)

Changed library structure, now with module system, separated into modules for the main Crossref search API (i.e., api.crossref.org) including higher level methods (e.g., registration_agency), content negotiation, and citation counts.
