@AlexVonB - good catch on the README.rst file, thank you! This pull request improves runtime for hierarchically deep HTML structures (as opposed to #186, which improves runtime for broad flat HTML structures). @AlexVonB , @AlextheYounga - this branch now includes #186. I did some local correctness and performance testing, but I would appreciate any additional testing you can provide so we can merge this in confidence. |

@AlexVonB, @AlextheYounga - I had one more look through the code and felt pretty good about it, so I merged it. |

Fixes #190.
Improves runtime by propagating the parent tag context downward into children. Python
set()objects are used because membership tests are fast and deduplication is automatic.In addition, the following "pseudo-parent" parent tag names are propagated:
_inline- parent include a heading,td, orthtag_noformat- parents include apre,code,kbd, orsamptagFor one of my large HTML testcases that has
<div>,<article>, and<section>hierarchy, runtime improves from 502 seconds to 261 seconds.This pull request changes the interface for
convert_*()functions by changing theconvert_as_inlineBoolean parameter to aparent_tagsset parameter, so this change should probably be made in a major version number change.
