Fixed item listing, moved margin-left to <li> #225

botzill · 2017-02-01T16:55:12Z

No unit tests yet! Will add soon.

About this PR. Basically there are scenarios like in the issue #224 and #202.

Scenario 1 - proper left/right margin:

Currently when we have a doc like:

(old code) will output this:

(new code) will output this:

So, basically proper margins are added to the <li> items like this:

<body><p>Heading 1</p>
<ol class="pydocx-list-style-type-decimal">
    <li style="margin-left:9.00em">AAA</li>
    <li style="margin-left:9.00em">BBB</li>
</ol>
<p>Heading 2</p>
<ul>
    <li style="margin-left:19.50em">CCCC</li>
    <li style="margin-left:19.50em">DDD</li>
</ul>
</body>

Scenario 2 - basically issue from #202:

If we have as input a list like this:

(old code) we get as output this:

(new code) while with new changes we get:

Now, this issues is related to the fact that listings like: B1,B2, C1,C2 are basically independent lists from the main one. This mean that they have a different NumberingProperties and, of course, different numId which is actually breaking the entire listing flow. Currently listing will works if NumberingProperties are the same and level_id is changing(which will cause proper nesting). Now, for this case I did the following(code commends as well 5a4d93a#diff-4aa70f6d5310ea0a57e5c20b629dc727R212):

Before we start to process numbering spans/items I read all the listing items(from components) and try to determine such scenarios and create a simple mapping like this:

child_parent_num_map = {
     "<child_num_id>": "<parent_num_id>",
    ....
}
parent_child_num_map = {
     "<parent_num_id>": "<child_num_id>",
    ....
}

Later, when we construct the span/items I do some checks and determine if we should start a new span or we already have a parent one and just add to it.
Check PR for more details relate to implementation and let me know what you think about this solution.

Now, this issues was tricky as I needed to understand basically the entire listing flow. Still not sure if I did it properly

Hello Chirica,

Thanks for the PR!

There's a lot going on here. It would really help if you could provide both a summary of what was wrong and what the new behavior is, and at least some minimal test coverage demonstrating the fix.

Thanks
-Wes

@winhamwr I think the discussion is in #224

botzill · 2017-02-01T17:11:43Z

Ou, I did not expect the PR here :). OK, I will make proper descriptions about it. Still some work in progress here. So, hold on for now.

Thx.

winhamwr · 2017-02-01T17:12:26Z

Thanks @kylegibson! The discussion there is great.

I guess that means we're just missing a bit of test coverage and a thorough review. I walked through the code itself and it looks high-quality. Thanks for that, Chirica!

So, hold on for now.

Will-do. We'll wait to hear from you before diving in.

botzill · 2017-02-01T18:05:59Z

OK, I did update the description with what I did so far. Please, if you have time, check the PR and let me know if you have any improvements. I did not covered 100% how listings are get constructed(fake lists as example).

Thx!

botzill · 2017-02-03T14:06:21Z

@winhamwr @kylegibson any chance you can check the current PR an let me know what you think about it?

Thx!

How would you feel about switching this conditional so that it was if properties.numbering_properties so that the else case was the 2-line case? Just a matter of preference, but I struggled for a bit reading this until I realized that the first case was essentially the "do nothing fancy" case.

I'd also love a comment explaining the do-something case like Numbering properties can define a text indentation on a paragraph

The (undocumented, sorry) coding standard this project follows is to use one line per kwarg when the definition stretches across lines.

It is on a new line, no?

Sorry that I wasn't clear. Like this:

def export_listing_paragraph_property_indentation( self, paragraph, level_properties, include_text_indent=False, ):

Actually, don't worry about these minor style issues, including my notes on comment capitalization/punctuation. I can handle all of that trivial stuff after we get this merged in. We can't expect you to read our mind on those things, since they aren't documented in our coding standards.

Nop, good to know ;).

Are we ignoring the possibility that only paragraph_ind_first_line is set on purpose? Is that case handled with this line?

Well, if paragraph is part of the listing then it's level will contain the left or hanging. I don't think we can have a listing paragraph where we don't have left/hanging on it's level and on paragraph but first line is set.

We go with the style of opening the parens and then indenting the next line, rather than using \.

like this:

prev_left_level_indentation = prev_paragraph.get_numbering_level( ).paragraph_properties.to_int('indentation_left')

Well, here we add margins to li elements, so no need for display: inline-block at this stage.

@jlward @kylegibson would either of you be willing to give this method a look? I understand what this is supposed to do (thanks to the excellent docstring), and I understand the code (looks good), but I don't understand the interaction between numbering_properties, abstract_num_id, and other concepts here to give it a confident review.

I just realized that this methods needs to be adapted to handle more cases, especially any nested separated list. Will look into it tomorrow and try to adapt for all cases. Any feedback is welcome.

winhamwr · 2017-02-16T23:08:09Z

We've given this a couple of days for review, and everything looks very solid to me. @botzill if you can get the python 2.6 tests passing, then I'll merge this in and fix the minor style issues.

botzill · 2017-02-17T06:00:55Z

Thx @winhamwr, sounds great! I have left some final things to finish related to setting proper margins for those separated nested lists. Hope will not take much time. I want to include that as well in this PR.

p.s Tests fixed.

botzill · 2017-02-17T15:02:33Z

OK, I think this PR is ready now. Did some changes related to separated nested lists. Now margins are properly set.
