User:Sbb/sandbox/Episode table
This is an experiment to determine if there is a substantial parser benefit or penalty when using different (otherwise equivalent) uses of the {{Episode table}} template.
Background[edit]
The {{Episode table}} template generates table header information for lists of episodes of TV shows. Usually, the episode tables are separated per season, and quite often, the episode tables are given their own articles, which are then usually transcluded in higher-level articles about the TV series or total episodes. For instance, the article on List of Family Guy episodes looks something like:
==Episode list==
===Season 1 (1999)===
{{main|Family Guy (season 1)}}
{{:Family Guy (season 1)}}
===Season 2 (1999–2000)===
{{main|Family Guy (season 2)}}
{{:Family Guy (season 2)}}
...
The Family Guy (season 1) article contains the following episode list:
<onlyinclude>{{#invoke:Episode table|main|background = #FBEC5C
|overall= 5 |season= 5 |title= 23 |director= 18
|writer= 25 |airdate= 16 |prodcode= 8 |country= U.S.
|episodes=
{{#invoke:Episode list|sublist|Family Guy (season 1)
| EpisodeNumber = 1
| EpisodeNumber2 = 1
| Title = [[Death Has a Shadow]]
| DirectedBy = [[Peter Shin]]
| WrittenBy = [[Seth MacFarlane]]
| OriginalAirDate = {{Start date|1999|1|31}}
| ProdCode = 1ACX01
| ShortSummary = [[Peter Griffin|Peter]] applies for [[welfare (financial aid)|welfare]] to support his family after losing his job. He receives a check for $150,000 due to a misplaced decimal point, and uses it to buy lavish presents for his family. [[Lois Griffin|Lois]] is upset when she finds out after receiving a new welfare check in the mail; Peter attempts to make her happy by dropping his surplus money out of a blimp above [[Super Bowl XXXIII]] with the help of [[Brian Griffin|Brian]]. Both are arrested by security guards and prosecuted for [[welfare fraud]]. At the courthouse, Lois pleads with the judge not to imprison Peter; [[Stewie Griffin|Stewie]], grudgingly coming to realize his dependence on his parents, influences the judge to reconsider the sentence.

<!-- ... deleted the remainder of episodes: {{$invoke|Episode list|sublist|Family Guy (season 1)}} -->
}}</onlyinclude>
Simplifying the pattern, it looks like:
<onlyinclude>{{Episode table
|episodes=
{{Episode list|sublist|(Show/season)}}
...
{{Episode list|sublist|(Show/season)}}
}}</onlyinclude>
But, using the |dontclose=y parameter, it could just as well be:
<onlyinclude>{{Episode table
|dontclose=y }}
{{Episode list|sublist|(Show/season)}}
...
{{Episode list|sublist|(Show/season)}}
{{End|Episode table|html=y}}</onlyinclude>
Note that in real articles, the table closure on the last line varies between {{End|Episode table|html=y}}, </table>, and even sometimes, clearly erroneously, }}.
Test article[edit]
I used the List of Annoying Orange episodes article because it is a huge article with over 10 template transclusions of {{Episode table}}, in an attempt to get some meaningful data about table parsing and parser function execution time. The results are shown below.
