问题描述
我希望能够转储包含长字符串的字典,我希望在块样式中具有可读性.例如:
I'd like to be able to dump a dictionary containing long strings that I'd like to have in the block style for readability. For example:
foo: | this is a block literalbar: > this is a folded blockPyYAML 支持加载具有这种样式的文档,但我似乎找不到以这种方式转储文档的方法.我错过了什么吗?
PyYAML supports the loading of documents with this style but I can't seem to find a way to dump documents this way. Am I missing something?
推荐答案import yamlclass folded_unicode(unicode): passclass literal_unicode(unicode): passdef folded_unicode_representer(dumper, data): return dumper.represent_scalar(u'tag:yaml,2002:str', data, style='>')def literal_unicode_representer(dumper, data): return dumper.represent_scalar(u'tag:yaml,2002:str', data, style='|')yaml.add_representer(folded_unicode, folded_unicode_representer)yaml.add_representer(literal_unicode, literal_unicode_representer)data = { 'literal':literal_unicode( u'by hjw ___' ' __ /.-.\' ' / )_____________\\ Y' ' /_ /=== == === === =\ _\_' '( /)=== == === === == Y \' ' `-------------------( o )' ' \___/'), 'folded': folded_unicode( u'It removes all ordinary curses from all equipped items. ' 'Heavy or permanent curses are unaffected.')}print yaml.dump(data)结果:
folded: > It removes all ordinary curses from all equipped items. Heavy or permanent curses are unaffected.literal: | by hjw ___ __ /.-. / )_____________\ Y /_ /=== == === === = _\_ ( /)=== == === === == Y `-------------------( o ) \___/为了完整起见,还应该有 str 实现,但我会偷懒:-)
For completeness, one should also have str implementations, but I'm going to be lazy :-)

Python 中是否有任何支持将长字符串转储为块文字或折叠块的 yaml 库?
