    Have added to HowTo a description for how to label equations

    In the course of this I restructured the section “How to make links to subsections of a page” by giving it a few descriptively-titled subsections.

    I was reminded of some things that I had wanted to add to the HowTo page, and now I finally got around to doing so:

    I added a new section How to organize and write content with new subsections:

    Oh, and now I have spotted and removed the subsection “How to ask questions”. I think we all agree that this initial idea we once had didn’t work out and should be abandoned, reproduced below just for the record:

    [ begin obsolete old text ]

    How to leave comments and questions

    If you want to make a comment or question about a page without changing its main content, then edit the page and put your comment or question in a query block as shown in this example:

    +-- {: .query}
How do I ask a question?
=--

    which produces

    +– {: .query} How do I ask a question? =–

    Note that a query block should be less permanent than the rest of the page; once your comment is addressed or your question is answered, you can probably remove your query block.

    If you want to ask a question of a specific person, then you can place a query block on their user page (which is just a page whose title is their name). You should be able to find all user pages here.

    If your comment or question is more general than a specific page or person, then try the n-Forum. Previous discussions have been on the General Discussion page and on an entry at the n-Cafe. These previous discussions should not be added to but you may find your question answered there. Important answers are being migrated to this How To and the FAQ. As this is a Wiki, if you find an answer to your question and feel it should be added to one of those then do so.

    That text shouldn't be removed entirely; it's still a formatting feature that's sometimes useful and should be documented.

    The section has been edited bit by bit over the years as we've pulled away from heavy use of query boxes. It ought to start by pointing people to the Forum (instead of ending with this as it last did) and then show how to make a query box if people want to.

    I will try to write a section like that now. … Done.

    In order to improve the order-by-relevance of the material, I moved up the section How to make links to subsections

    I see now that this has a little bit of overlap with the new section on how to put references that I just added, but it’s maybe still good to have the latter

    This page is great, and I will definitely reference it in the future, but after about a year or two of editing here, I’m not sure I’ve ever seen it.

    I think it would be very nice if the editing page always included a link to this page right at the top. The edit page has some nice markdown tips, but this page has stuff like table of contents and theorem environments that are less common.

    I think it would be very nice if the editing page always included a link to this page right at the top.

    That sounds indeed like a good idea: include a pointer to HowTo in the line on top of each nLab entry.

    We will have to bring this to the attention of Richard. Probably he will see this here. If not, let’s remember to contact him about it.

    I noticed that the text under Software requirements was badly outdated.

    I rewrote a bit, to the best of my knowledge, in particular I mentioned MathJax (which wasn’t around yet when that section was last edited!) But somebody more expert should please check, especially the following points:

    • is installing STIX fonts still something one needs to do?

    • what’s the latest on Opera supporting MathML? It said something about the “recent” version, but that will be long outdated now.

    • Is it still true that IE (or any other browser) works with or needs the MathPlayer plugin? My impression is that this is a thing of the past?

    Anyway, somebody who knows about this might want to start this section completely from scratch, with up-to-date information.

    I don’t think STIX fonts are needed… at least, I haven’t installed them on my new computer and things still look fine.

    • CommentTimeJun 18th 2018

    just downloaded the latest Opera-version to check. But it calls MathJax instead of rendering MathML natively. So I removed that outdated line regarding Opera that we had. Also removed the statement about IE needing MathPlayer.

    So now it just says that Firefox is currently the only browser with native MathML support, the rest of the crowd falls back to MathJax.

    Which is a pity. Since its last update Firefox has become ridiculous, tending to take several seconds for opening new windows.

    (I followed the instructions that are offered online for how to work around this most unbelievable issue, but first of all I don’t actually want to clear my browsing history, as I am being advised, and it didn’t actually help for more than half an hour anyway. )

    The howto still mentions the Stylish plugin. However, there have been problems with it spying on people. There is a replacement. As I’m not using the plugin myself, I won’t change the howto, but people using it (Mike?) may want to have a look.

    Excellent. Thank you!

    I have further specified the pointer to the nnForum to a pointer to this particular thread here, to free the user of the need to create a new thread, come up with a decent thread title etc.

  24. Good idea, thanks very much!

    Add description of LaTeX syntax for theorem environments. Move ’Technical’ section to the bottom. Change instructions for ’how to remove a page’ to remove mention of the old making-the-page-empty method.

    diff, v166, current

  28. I think HowTo could still do with quite a bit of work, for example rearranging parts of ’How to organize and write content’ and ’Special typesetting features’ into one clean section which covers all typesetting, putting everything else, like CSS, how to ask questions, etc, in some other section. I’m also not sure about the ’Template’ page. I think now we could just link to a few particularly nicely constructed pages (many of them have a cohesive style, so it shouldn’t be too much of a problem).

    We should add a bunch of examples of tikzcd-diagram typesetting, with output in parallel to the source code, both for convenient copy-and-pasting for regulars, as well as a guide for newbies

    I have added the example of adjoint functor notation here.

    But there is a weird bug: You’ll see that the very last line of the escaped code is lacking its backslash – that’s because when adding that backslash (in the escaped code!) I get an error message upon “submit”-ing the entry (?)

    Added explanation for how to format xymatrix diagrams.

    diff, v169, current

  33. Tweaked xymatrix examples according to a slight change in syntax. Also fix the ’bent arrows’ example, and add 2-cell example.

    diff, v171, current

  34. Make source of Tikz and Xymatrix examples visible on the page.

    diff, v172, current

  35. I have now fixed the issue mentioned in #30, also discussed in #43 here, to allow for the diagram code to be displayed verbatim. See here for the github commit.

    As Urs suggested earlier in the thread, it would be good to collect together in the HowTo all common diagram shapes, e.g. commutative squares, triangles, 2-cells, …

  36. Added how to centre/center using the new(-ish!) LaTeX syntax to the HowTo.

    diff, v173, current

  37. Some links in the “How to edit nLab pages in your favorite text editor” section did not work anymore. I put there some links to some Firefox addons that are convenient to my impression.

    diff, v178, current

  38. Elaborated a bit on captions for graphics when using imagefromfile, and added some advice on floating graphics.

    diff, v180, current

  39. The newer syntax for table of contents was not documented, now added.

    The newer syntax for sectioning is still not documented.

    diff, v181, current

  40. As for troubles with h6. I don’t think that it is a feature that the “Theorem” shows up in the table of contents at HowTo#latex_syntax

  41. Updating available theorem environments in the ’new’ syntax, i.e. the LaTeX-like syntax.

    Where the new environment-syntax was mentioned (here) with but a pointer to the page’s source, I have added display of the code that the reader needs to know.

    Apparently the issue is that the new syntax doesn’t allow itself being escaped, but I worked around it:

    \begin{theorem} \label{SomeTheorem} Some theorem. \end{theorem} \array{ \mathrlap{ \backslash\text{begin}\{\text{theorem}\} } \\ & \;\; \mathrlap{\backslash\text{label}\{\text{SomeTheorem}\}} \\ & \;\; \mathrlap{\text{Some theorem.}} \\ \mathrlap{\backslash\text{end}\{\text{theorem}\}} }

    :-)

    (So this won’t allow being copy-and-pasted usefully, but at least the reader gets to see what they need to see.)

    (Oh, in fact, copy-and-pasting the code displayed in #42 works just fine.)

  44. Nice, thanks!
