ruamel.yaml is a YAML parser/emitter that supports roundtrip preservation of comments, seq/map flow style, and map key order
Project description
ruamel.yaml
ruamel.yaml is a YAML 1.2 loader/dumper package for Python.
ChangeLog
0.12.18 (2016-11-16):
- another fix for numpy (re-reported by Nathanial Burdic)
0.12.17 (2016-11-15):
- only the RoundTripLoader included the Resolver that supports YAML 1.2
now all loaders do (reported by mixmastamyk)
0.12.16 (2016-11-13):
- allow dot char (and many others) in anchor name
Fix issue 72 (reported by Shalon Wood)
- Slightly smarter behaviour dumping strings when no style is
specified. Single string scalars that start with single quotes
or have newlines now are dumped double quoted: "'abc\nklm'" instead of
'''abc
klm'''
0.12.14 (2016-09-21):
- preserve round-trip sequences that are mapping keys
(prompted by stackoverflow question 39595807 from Nowox)
0.12.13 (2016-09-15):
- Fix for issue #60 representation of CommentedMap with merge
keys incorrect (reported by Tal Liron)
0.12.11 (2016-09-06):
- Fix issue 58 endless loop in scanning tokens (reported by
Christopher Lambert)
0.12.10 (2016-09-05):
- Make previous fix depend on unicode char width (32 bit unicode support
is a problem on MacOS reported by David Tagatac)
0.12.8 (2016-09-05):
- To be ignored Unicode characters were not properly regex matched
(no specific tests, PR by Haraguroicha Hsu)
0.12.7 (2016-09-03):
- fixing issue 54 empty lines with spaces (reported by Alex Harvey)
0.12.6 (2016-09-03):
- fixing issue 46 empty lines between top-level keys were gobbled (but
not between sequence elements, nor between keys in netsted mappings
(reported by Alex Harvey)
0.12.5 (2016-08-20):
- fixing issue 45 preserving datetime formatting (submitted by altuin)
Several formatting parameters are preserved with some normalisation:
- preserve 'T', 't' is replaced by 'T', multiple spaces between date
and time reduced to one.
- optional space before timezone is removed
- still using microseconds, but now rounded (.1234567 -> .123457)
- Z/-5/+01:00 preserved
0.12.4 (2016-08-19):
- Fix for issue 44: missing preserve_quotes keyword argument (reported
by M. Crusoe)
0.12.3 (2016-08-17):
- correct 'in' operation for merged CommentedMaps in round-trip mode
(implementation inspired by J.Ngo, but original not working for merges)
- iteration over round-trip loaded mappings, that contain merges. Also
keys(), items(), values() (Py3/Py2) and iterkeys(), iteritems(),
itervalues(), viewkeys(), viewitems(), viewvalues() (Py2)
- reuse of anchor name now generates warning, not an error. Round-tripping such
anchors works correctly. This inherited PyYAML issue was brought to attention
by G. Coddut (and was long standing https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=515634)
suppressing the warning:
import warnings
from ruamel.yaml.error import ReusedAnchorWarning
warnings.simplefilter("ignore", ReusedAnchorWarning)
0.12.2 (2016-08-16):
- minor improvements based on feedback from M. Crusoe
https://bitbucket.org/ruamel/yaml/issues/42/
0.12.0 (2016-08-16):
- drop support for Python 2.6
- include initial Type information (inspired by M. Crusoe)
0.11.15 (2016-08-07):
- Change to prevent FutureWarning in NumPy, as reported by tgehring
("comparison to None will result in an elementwise object comparison in the future")
0.11.14 (2016-07-06):
- fix preserve_quotes missing on original Loaders (as reported
by Leynos, bitbucket issue 38)
0.11.13 (2016-07-06):
- documentation only, automated linux wheels
0.11.12 (2016-07-06):
- added support for roundtrip of single/double quoted scalars using:
ruamel.yaml.round_trip_load(stream, preserve_quotes=True)
0.11.0 (2016-02-18):
- RoundTripLoader loads 1.2 by default (no sexagesimals, 012 octals nor
yes/no/on/off booleans
