I just ran into the following problem: For a technical document I’m creating with LaTeX, there are a lot of sections that have a repeated/consistent format. Is there a way to Apply Multilingualism to Contents Label in the TOC Template or Even Custom Title? And it would hide header G even though it is a level-3 heading just like header B, because header G is shown at the third level in the TOC while header B is shown at the second level.. This is implemented as a CSS class in the MediaWiki:Common.css. Using {{TOC limit}} on this page would not hide header D, because even though it is a level-6 heading it is shown at the second level in the TOC. __NOTOC__ disables the TOC entirely. And limit=2 will hide all subheadings leaving only the main headings. For instance using limit=4 will hide the fourth level and deeper subheadings in the hierarchy. Is there a scroll-able support / hack for TOC in mediawiki? You can specify a different limit by adding a header level: {{TOC limit|4}} 4 allows for third-level headings, e.g. Using {{TOC limit}} on this page would not hide header D, because even though it is a level-6 heading it is shown at the second level in the TOC. You can specify a different limit by adding a header level: {{TOC limit|4}} 4 allows for third-level headings, i.e. This is implemented as a CSS class in the MediaWiki:Common.css. "1.1.1", but omits any subheadings below that from the TOC. For further details see the descriptions in … I just ran into the following problem: For a technical document I’m creating with LaTeX, there are a lot of sections that have a repeated/consistent format. This works by hiding the lower levels with CSS. WP:Blanking sections violates many policies, WP:Add wikilinked sections to balance NPOV, m:Help:Expansion_depth#Transcluding_a_template, https://en.wikipedia.org/w/index.php?title=Wikipedia:Avoiding_MediaWiki_expansion_depth_limit&oldid=966530395, Creative Commons Attribution-ShareAlike License, {{formatnum: {{#expr: 5* {{formatnum:21,001|R}} }} }} → 105,005, This page was last edited on 7 July 2020, at 16:20. "1.1.1", but omits any subheadings below that from the TOC. The effect here is that I'll have 2 boxes (the TOC box in the scroll box) which makes it not look good. A single test for running over the top of the hierarchy is applied (in {{Findall taxa/5}}). By setting a number value for |limit=, only headings of … Cautions Thanks ! I can accomplish this with __TOC__, but doing this on every single page is infeasible. limit Limits the depth of subheadings shown. Need new example(s) since the template previously used here to illustrate the issues is now coded in Lua and doesn't cause problems. You can specify a different limit by adding a header level: {{TOC limit|4}} 4 allows for third-level headings, e.g. Number: optional: Width: width 1: Overrides the CSS width. Section names should preferably be unique withi… An example is the traversal of the taxonomic hierarchy stored in templates with names of the form "Template:Taxonomy/taxon". So, a calculation which removes commas, multiples the amounts, and then re-adds commas will nest 3 levels deep: Omitting formatnum reduces 1 level: In many cases, it is unavoidable to remove commas from numbers, so formatnum is then used to drop any commas, {{formatnum:21,001|R}}, but in an extreme case, require the input to contain no commas, and reduce the expansion depth by 1 level by omitting {formatnum}. Using large templates together in an article paragraph is rarely a problem. And it would hide header G even though it is a level-3 heading just like header B, because header G is shown at the third level in the TOC while header B is shown at the second level.. For example ==Section Header==
will not work. As noted previously, the parser function {{#expr:...}} consumes 1 level of expansion depth, as does {{formatnum:...}}. I can't say if it can have possible side effects on something else, but for my needs...it works. I have not found an extension that does this either. For example, {TOC \l 1-4 } builds a table of contents from TC fields that assign entries to levels 1-4. As an example, a 3-nested stack for 3 #ifexpr can be reduced to a sequence of 3 separate uses of #ifexpr: Alternatively, a #switch can be used to check a parameter when equal to some specific values: By keeping the nesting of #if, #ifeq, #ifexpr or #switch to just 1-level coding, then the template would have a total nesting depth of just 2 levels. limit Limits the depth of subheadings shown. Avoid placing the TOC in a visually poor location. Builds a table of contents from TC fields that assign entries to one of the specified levels. The refactoring of both calculations into a single {#expr} can reduce the nesting by 1 level: The use of parentheses "( )" allows a single {#expr} calculation to combine each formula, inside others, as only 1 level of expansion depth. Table of Contents. And limit=2 will hide all subheadings leaving only the main headings. Is it possible? Within a template, the nesting can be reduced by moving each if-expression to be outside another if-expression, or by combining the logic into compound conditions, such as "#ifexpr:|a=b and c=d..." rather than have a #ifexpr nested inside an outer #ifexpr. "1.1.1", but omits any subheadings below that from the TOC. Natrashafierce (talk) 20:23, 23 August 2014 (UTC). NOTE THE DANGER: When the depth limit is exceeded, not all templates die, but rather, they simply generate the wrong results (from the remainder of the template) and keep going, as if nothing were wrong. This page was last edited on 23 September 2020, at 07:24. You can specify a different limit by adding a header level: {{TOC limit|3}} 3 allows for third-level headings, e.g. Need to check which templates used here to illustrate the issues are now coded in Lua. Can I add Table of Content of one page to another page? In some cases, avoiding the use of other templates inside a template can also reduce the nesting: whereas using a #ifexpr increases the depth by 1 level, invoking another template containing that #ifexpr increases depth by 2 levels. Would a skin do it? — Preceding unsigned comment added by 14.207.179.110 (talk • contribs) 05:39, 23 May 2017‎, IDEA: when __NOTOC__ is used, a little [TOC} etc. "1.1.1", but omits any subheadings below that from the TOC. In the HTML code for each section there is an anchor සැකිල්ල:H:mlw with both "name" and "id" attributes holding the section title. ` into my company wiki page but it does not work. This is implemented as a CSS class in the MediaWiki:Common.css. If I poke into the html, I can see anchor tags that are blank or have "_#". is the only variant supported on Wikimedia projects, and only on smaller projects. It would generally be helpful to know where I'd go if I wanted to add something like a containing div around things like the ToC. Each template has a parameter |parent=parent-taxon. --X-Savitar (talk) 16:08, 8 April 2020 (UTC), The solution below, no longer works since MediaWiki 1.29. "1.1.1", but omits any subheadings below that from the TOC. It contains the advice or opinions of one or more Wikipedia contributors. There are a ton of variables and hooks and arrays that I suspect this is buried in, and I only have moderate programming ability so I can't dig it up on my own. I have not see anything relevant in the console, but I'm really a novice in LaTeX. Positioning the TOC . You can also use Special:ExpandTemplates to examine the results of template use. __TOC__ forces the TOC to appear at the point where the magic word is inserted instead of the normal location. Manual:Table of contents#Depth refers to MediaWiki:Common.css in order to find the relevant toclimit- styles, but it appears as though Common.css is just empty. All during 2009-2010, the nesting limit has been only a mere 40 levels of nested if-then-else (or … Valid values are 2,3,4,5,6,7.The functionality for hiding unwanted elements is defined at MediaWiki:Common.css. |toc=on). Conflicts. those numbered "1" and "1.1" in the TOC. I'm not sure if this is a result of most of the styles being moved into a default location and that file just being used for overrides or something. Using {{TOC limit}} on this page would not hide header D, because even though it is a level-6 heading it is shown at the second level in the TOC. The Mediawiki restriction on expansion depth results in significant increases in processing time through the necessarily inefficient coding that results. Section linking. those numbered "1" and "1.1" in the TOC. Fortunately, many common templates can be rewritten to unnest the if-else logic or avoid using too many embedded templates. The default position of the TOC is directly above the first section heading. My question is: how would I even begin to change that? This works by hiding the lower levels with CSS. "1.1.1", but omits any subheadings below that from the TOC. I want to make an index page that always show table of contents of another pages. For instance using limit=4 will hide the fourth level and deeper subheadings in the hierarchy. limit Limits the depth of subheadings shown. It regards the step of producing the expanded wikitext. Conflicts. The technical limits of expansion depth are explained in the pages: The limits were chosen to thwart denial of service (DoS) attacks being caused by very large or complex templates. A suggested alternative is … However, we know from the discussion above that inside a template that is itself expanded at most 20 nested template calls are possible, so it would appear that this is the maximum number of levels of the taxonomic hierarchy that can be processed. I've looked through my skin, I've looked through all the skinning manuals I can find, I even looked through SkinTemplate.php and Skin.php in the MediaWiki files, but I can't figure out which file it is -- if there even is a single file -- that simply lays out the order the different elements appear in the page code. limit Limits the depth of subheadings shown. Avoid placing the TOC in a visually poor location. |toc=on). Example: create. Conflicts. The maximum level of headings displayed on the TOC is defined in $wgMaxTocLevel. And limit=2 will hide all subheadings leaving only the main headings. rate_limit (bool) – Use rate limiting to limit calls to the site rate_limit_wait ( timedelta ) – Amount of time to wait between requests cat_prefix ( str ) – The prefix for categories used by the mediawiki site; defaults to … TOC levels versus wikitext header levels The advanced version covers all functions of the older variant, here only the latter is explained. Worse, a template which is itself transcluded cannot have more than 20 levels of nested templates. I'm not sure where to go about finding these. What is not affected: Typically, large templates can be invoked, together, in article text without reaching the limit. Sectionsare created by creating their headings, as below: Headers with only one equals sign on a side (=text here=) causes a title the size of the page name. the page may malfunction due to MediaWiki limits. And limit=2 will hide all subheadings leaving only the main headings. Manning Bartlett (talk) 04:08, 13 March 2013 (UTC). You can specify a different limit by adding a header level: { { TOC limit |3}} 3 allows for third-level headings, e.g. Using {{TOC limit}} on this page would not hide header D, because even though it is a level-6 heading it is shown at the second level in the TOC. I'm not sure if this is a result of most of the styles being moved into a default location and that file just being used for overrides or something. Omitted sections still have section edit links in the article body; the main use for this template is situations where you want section edit links for ease of editing but don't want to clutter the table of contents. Avoid placing the TOC in a visually poor location. Combining nested expressions avoids 1 level: In rare cases, a calculation might contain another nested calculation. A problem will be that applied to a taxon with fewer than k2-1 levels above it, the code will go over the top of the hierarchy, which is wasteful of processing time, even if it does not generate an error. You'll need to edit the TOC field to add a switch, \l, which is described in Help as follows: \l Levels. Cautions Here my question, I want to have the Table of Contents in the page, but there are one header & subheaders that I don't want to show in it. [1] The severe limit is so restrictive that some templates cannot function properly when invoked inside other large templates. The syntax of the sections hasn't changes (since when it used to work). "1.1.1", but omits any subheadings below that from the TOC. And if not, what would be a "recommended" way to edit the files? The template limits the depth of a table of contents. Change the "hide" link text to "show" or vice versa. Therefore, the element with the, When the code hides the TOC, it doesn't change the "hide" link text to "show". To customize this for individual pages, the TOC can be enclosed in an element with class toclimit-, if the appropriate CSS rules are defined in the pages CSS. This is implemented as a CSS class in the MediaWiki:Common.css. However, care must be taken to not change the overall effect of the logic, when shifting the nesting of each #ifeq or #ifexpr. You can specify a different limit by adding a header level: {{TOC limit|4}} 4 allows for third-level headings, i.e. Unfortunately, it's impossible to completely prevent this happening, because adding #if: expressions to test for the highest level being reached greatly increases the expansion depth and hence greatly reduces the maximum level that can be reached. Changes can be tested faster by copying a section of code to be edited (and debugged) separately. The template defaults to including only the first- and second-level headings, e.g. but, it seems as though if you went with MediaWiki:Common.css, you would need a different class for each number of columns (or column width). As example text, the header text would be Contents in English and Sommaire in French. A practical example of this approach, used in determining the correct colour to be applied to an automated taxobox, will be found at {{Findall taxa}}. Any prior text is placed before the TOC. This is a user preference, set in Special:Preferences (Preferences > Appearance > Advanced options > Show table of contents). This solution is working for me on 1.34.0 (I was unable to make it work in Vector skin with the. Limit: limit: Limits the depth of subheadings shown. This essay covers issues about the MediaWiki version 1.16 "expansion depth limit" for the nesting of templates and if-logic. The template works by hiding the lower levels with CSS. I want it to always sync and don't need to update it manually. For instance using limit=4 will hide the fourth level and deeper subheadings in the hierarchy. And it would hide header G even though it is a level-3 heading just like header B, because header G is shown at the third level in the TOC while header B is shown at the second level.. The template works by hiding the lower levels with CSS. I just want to simple have a box with the TOC and which is scroll-able. those numbered "1" and "1.1" in the TOC. And it would hide header G even though it is a level-3 heading just like header B, because header G is shown at the third level in the TOC while header B is shown at the second level.. Using {{TOC limit}} on this page would not hide header D, because even though it is a level-6 heading it is shown at the second level in the TOC. Any prior text is placed before the TOC. Consequently, many people have tried to write templates as if they were writing computer software for modern computer systems, totally unaware of the unusual restriction of 40 levels of nested logic, where other computer software would allow 300, or perhaps unlimited, levels of nesting. However, this is not the case. You can specify a different limit by adding a header level: { {TOC limit|4}} 4 allows for third-level headings, e.g. {{ TOC limit }} can be used to control the depth of subsections included in the TOC. And limit=2 will hide all subheadings leaving only the main headings. This is implemented as a CSS class in the MediaWiki:Common.css. Reducing expansion depth: The nest-levels can be reduced, inside large templates, by rewriting some of the nested if-else-if-else logic as non-nested if-then-if-then-if-then, or using a #switch outside of the if-then logic. With k=4, the template Proc1 would have the form: Then the template Proc2 would be identical other than calling Proc3, and so on. You can also use Special:ExpandTemplates to examine the results of template use. To include a Table of Contents (ToC), set the parameter toc (e.g. Using {{TOC limit}} on this page would not hide header D, because even though it is a level-6 heading it is shown at the second level in the TOC. Need to check which templates used here to illustrate the issues are now coded in Lua. If we have N such templates, from Proc1 to ProcN, with all but the last calling the next in the sequence, then it can be shown by theory and experiment that: Some elementary calculus shows that for a given L, the optimum is at N = k. Thus to reach 49 levels, N = k = 7, and the expansion depth will be A + 14. Of course, some cases will require nesting of the #ifexpr coding to handle multiple conditions which trigger extended processing with some nested #ifexpr coding to handle other options. The template defaults to including only the first- and second-level headings, e.g. Positioning the TOC . See MediaWiki:Common.css. "1.1.1", but omits any subheadings below that from the TOC. And it would hide header G even though it is a level-3 heading just like header B, because header G is shown at the third level in the TOC while header B is shown at the second level.. For instance using limit=4 will hide the fourth level and deeper subheadings in the hierarchy. Number: optional: Width: width 1: Overrides the CSS width. For example, is there a way to have the header within the TOC modified to match the applicable language if an individual selects the other language page under the navigation menu (left side) and it automatically modifies the applicable language setting, as well (top right) with that click rather than an individual having to change the language setting in top right as an additional steps? All during 2009-2016, the nesting limit has been only a mere 40 levels of nested if-then-else (or nested templates) invoked inside other templates. The table obeys the same layout rules as the __TOC__ magic word. WP:UNNEST. The default position of the TOC is directly above the first section heading. This essay covers issues about the MediaWiki version 1.16 "expansion depth limit" for the nesting of templates and if-logic. This essay, WP:Avoiding MediaWiki expansion depth limit, covers issues about the MediaWiki version 1.16 "expansion depth limit" for the nesting of templates and if-logic. I have changed the CSS to float the ToC left, but I need it to come directly after the H1 heading on the page, rather than before the first H2 heading, for the text to wrap how I want it to. This step can be isolated from the step of rendering the expanded wikitext by using Special:ExpandTemplates. Users can individually opt to have the table of contents hidden. This is hard-code solution, if you find extension solution, please mention it. http://en.wikibooks.org/wiki/MediaWiki_User_Guide/Sections_and_Headings#Headings_not_in_TOC, https://www.mediawiki.org/w/index.php?title=Manual_talk:Table_of_contents&oldid=4128462, Creative Commons Attribution-ShareAlike License, Add the following line at the beginning of the method, It doesn't always work. The MediaWiki software that powers Wikipedia has several parameters that limit the complexity of a page, and the amount of data that can be included. Unknown: optional When the code executes, the page may not have been fully loaded or parsed. Is there a way to accomplish this? The parent of taxon can be found via {{Taxonomy/taxon|machine code=parent}}, thus. the page may malfunction due to MediaWiki limits. So, I suspect something in MediaWiki text parser if failing to properly turn my section headers into anchors that TOC depends on. And it would hide header G even though it is a level-3 heading just like header B, because header G is shown at the third level in the TOC while header B is shown at the second level.. Expansion of templates, parser functions, variables (on this page collectively called templates in italics), and template parameters (tplargs) is subject to an expansion depth limit of 40. For example: {{TOC left|width=30%}} Depth. Avoid placing the TOC in a visually poor location. The template defaults to including only the first- and second-level headings, e.g. Using {{TOC limit}} on this page would not hide header D, because even though it is a level-6 heading it is shown at the second level in the TOC. In many computer systems, such nesting of if-else logic is allowed to exceed 100 levels, or perhaps unlimited levels, and hence, many people from computer backgrounds might be stunned to realize that the MediaWiki parser had severely limited such nesting to a mere, shallow 40 levels deep, all during 2009–2021. That looks. or whatever tiny marker should still show up, that the user can push, revealing the Table of contents. Jidanni (talk) 12:28, 12 December 2017 (UTC), Hi, I'm wondering if there is an option somewhere (it seems not) or an easy hack to automatically display the TOC when there are 3 or more headings, instead of the treshold of 4.--Varlin (talk) 21:25, 24 January 2020 (UTC), When a TOC becomes too long, is it possible to make it scroll-able within a particular box? When you create a section header, you can't have other content on the same line. Table of Contents. The main worry is when using large templates inside an infobox or deeper inside the coding of other templates (when editing a large template). Quadra23 (talk) 17:02, 20 January 2015 (UTC). This template inserts a Table of Contents which omits subheadings beyond a certain depth. An quick an dirty way to have the TOC start collapsed.
