@egreg: To risk the war ... (tex.stackexchange.com/q/28836/86), I use the \coloneq(q?) quite a lot but I also back it up with words. When scanning a text, I don't always see every word but the \coloneqqqqq stands out and says "here's where it was defined". Then I read the surrounding text to reach enlightenment. So there's a place for symbols, but I agree that they should not replace the text.
@AndrewStacey For some time I had a good balance (unwillingly) between my questions and answers. I always had the same amount. Now I have more answers than questions. I should ask more :-)
@Raphink I'm not sure that equal numbers is a "good balance". Obviously, the "more expert" you are, the greater the shift you'll have to answers over questions. So I would expect some sort of curve that started high on the "questions" axis and headed towards the "answers" axis as the user's reputation increased.
@AndrewStacey A consistent use of \ceq (for brevity) would require it in many more places than it's actually used by \ceqaddicts. Using a symbol just for emphasis is wrong from a mathematical point of view (but there are worse things around, and this is not a capital sin). Completely different is its use in computer science in syntax rules, for example; or in formal logic as a metalinguistic symbol ("stands for" is what they say when defining a new abbreviation for simplifying formulas.
In tex.stackexchange.com/questions/10558/… I read about pplatex. Until now I wasn't able to make it run under osx. Does anyone have experience with pplatex?
@egreg Agree on all points. I'm certainly not setting myself up as an example to be copied, nor saying that my behaviour is exemplary in any form. Just trying to explain what I do. If there's a better way to achieve the same effect, I'd love to know. I do find myself wanting to distinguish visually between "equals by declaration" and "equals by dint of the huge five-page proof we've just slogged through".
@AndrewStacey That's the difference between well and badly written mathematics. I ended studying Latin many years ago, but I can read and understand Gauß's "Disquisitiones Arithmeticae" just because it's well written mathematics (and doesn't use \ceq). :)
@egreg That doesn't help! There's a difference between knowing that ones mathematical writing is (to be blunt) rubbish, and being able to do something about it. It's like teaching: no-one ever tells you how to do it, you're just expected to "pick it up" as you go along. (Yes, I do know of texts on writing mathematics, but they only give general principles and I'm very much an examples-person).
@egreg I can relate a similar story: I stopped speaking French many years ago, but during my PhD had a copy of one of Grothendieck's texts permanently open and could - with one notable exception - understand what he was saying.
@egreg: On other things, thinking about redefining labels and references, on the first such question (tex.stackexchange.com/questions/28894/modify-eqref-command/…) the questioner asked me if there was anywhere else that the equation number would get put, other than the label of the equation and in a reference. I couldn't think of any, can you?
@AndrewStacey I'm a bit afraid about the interaction with hyperref; but \eqref uses \ref and I don't think that hyperref hooks into \eqref as well. I don't see any use of \tagform@other than producing the equation number (or tag) and in \eqref.
suppose a file with code (*.cpp, *.php, or whatever). There's a lot of symbols like '$', '{', '}' what will definetely be disliked by TeX. I want to make a documentation from a code file. Maybe you heard of some templates for working with code?
Thank you in advance!
well, without the code, I can't tell you anything :) I've once crated such an algorithm with a self-written line breaking algorithm and I have made the lines higher and only counted spaces that overlap a certain amount with a helper array. I don't want to look it up though because it was in my diploma thesis and I don't want to read this again.
@AndreyVihrov there is none. The best I've found is "Rivers: In a paragraph of text, a series of wordspaces that accidentally align vertically or diagonally, creating an awkward flow of white space within the column of text"
I have added a first version of an algorithm to detect rivers using Lua to the impnattypo package on github. To use it, simply use the rivers option:
\usepackage[draft,rivers]{impnattypo}
Here is an example result:
Beware that there might still be some bugs ;-)
I think it would be better later on to take in consideration the orientation of the river
you can have diagonal rivers that are problematic, but when it goes left and right alternatively, it's not a big deal in quite a few cases
I'd have to really narrow the definition of problematic rivers
@JosephWright Thanks! Since I'm suggesting a fix to someone else (an end user) to fix a problem with package incompatibiliy, and both \appto with etoolbox and \g@addto@macro both seem to solve the problem, I don't think there's a need for my own local equivalent. Are there any unforseen problems with using the global version that might crop up?
@AlanMunn Assuming this is not done repeatedly on a local macro, all is well. (Mixed local and global assignments can exhaust the save stack, but this is not normally an issue.)
I'm assuming that it's okay to alter the macro globally, of course
@JosephWright Simple is in the sense that it has no arguments; otherwise \apptocmd from etoolbox is necessary (with limitations). Your \myappto should be \long.
\long\def\appto#1#2{\expandafter\def\expandafter#1\expandafter{#1#2}} is simpler (but has no check on #1 being a macro).
You observation about shorthands is correct. Loading mathspec redefines \sigma to "σ, makes " active and \lets a certain control sequence to this character. Loading polyglossia with the russian option makes " active again and overwrites the previous definition of ". mathspec also sets up " to be ...
@AndreyVihrov As I wrote in the comment, Polyglossia is at fault because it calls \initiate@active@char also if shorthands are not required. One should modify the code, issuing the call only if the shorthands are asked for. It's possible to enable them globally or locally for each language that supports them, but in this case the \initiate@active@char routine is called.
Supporting mathspec along with shorthands seems quite complicated, but at least one can warn users that shorthands must not be activated if mathspec is loaded.
I hope some of the most active voters apply for SE sponsored membership in TUG, because they highlight quality and they ensure that other active members get more access to site features. Reading and validating is a deserving task.
Maybe we should do the reverse nomination for TUG membership. You have to sign the list if you don't want membership. Then SE can go through the list of everyone else to decide who to award it to.
I'd also say that it would be good for us directly if we have lots of people nominating themselves. It's a way of saying "Thank you" to SE and showing that we appreciate them becoming an institutional member of TUG. So don't think of it as putting yourself forward, think of it as saying, "When it comes to this time again next year, we definitely want SE to renew its membership."
So, for example, anyone who's committed enough to this site to spend time in chat should nominate themselves. Consider it a penance for talking about football all the time. (If it were rugby, now, that would be different.)
@StefanKottwitz: as you're here, would you like to deal with the top question on the "active" view?
Anyone any views on this question: tex.stackexchange.com/q/26378/86 ? @lockstep: you've a lot of experience with what should be closed (and why), what do you think?
Out of curiosity, how much spam do we get? I don't get the sense that there's loads, but then it might all be being dealt with before I ever see it. On occasion I see some deleted answer, but not often enough that I feel we have a problem.
@Raphink: Can your code to highlight repetitions do anything with highlighting? It seems that as you're working at the PDF level, you can find out about the height of the current line - which is one of the main difficulties. See, for example, tex.stackexchange.com/q/24036/86
@Raphink What I mean was, if I (in the TeX code) mark a couple of places, can you (via your Lua code and pdfliterals) colour in the background between those places with the correct height?
@Raphink: Okay, so if I mark a point in the text, what I'd like to do is save the coordinates to the aux file not of that point itself, but of the top and bottom of the current line at that point.
@egreg Yes, they are good to watch. Was it them that got to the semis last time? I remember watching the third-place play-offs. I think it was Argentina against France. Argentina (if it was them) played as if they were in the final. France played as if they weren't there.
@AndrewStacey I am not Raphink, but this is possible. The green line with the formula would have the height of the formula though and that's not really beautiful.
@AndrewStacey you want to complete the highlighting when it's partial like in the case of the math in the question?
@AndrewStacey, @Patrick : why not do that in Lua altogether? What I've done in two packages is that I have two implementations, one in pure TeX and one in Lua, and the switch is done automatically using \ifluatex so the functionalities are nicer when using LuaTeX, but still there somehow when using another rendering engine.
@Patrick You mean you aren't one of Raphink's sockpuppets? I agree that it wouldn't be beautiful in that case. However, I'm using highlighting in maths-only places where the highlighter should be wider. I'd also say that this sort of thing should be configurable and shouldn't be totally automatic, but it'd be good to make the configuration as easy as possible.
Here's another that's borderline, and the length of time with no response from the OP tips it over that line for me: tex.stackexchange.com/q/26470/86
@AndrewStacey Well, I am @Raphink. I ask questions and with my other ID I comment my questions that they are really clever questions. :) I am not sure how math is presented in TeX's nodes, so there could be an automatic solution...
@AndrewStacey That would explain it. :-) Ah, I know what a try is. :-)
The guy at ESPN always explains the rules and how the games work. I don't get some concepts, but it's quite nice and entertaining to watch it. Specially now with the World Cup.
@AndrewStacey I live it indirectly, as my brother's son is quite good. At just 18 he's scrum half in a second division team. And I live in Padova, where there's one of the best Italian teams (at least it was some years ago and it's improving).
@AndrewStacey But I'm more into basketball, having been involved in it for almost 40 years. Ouch!
@AlanMunn Really you weren't there? Somebody here always tells me that I was at Springfield with Naismith: in our local officials' association I'm the one with the least association number.
@Raphink On-topic, though I ponder "Not a real question". I'd say that detection of rivers was the whole of it. Avoiding rivers feels (on the basis of almost nothing) like it's too fine to be left to the computer to do automatically. I'd rather think about the paragraph myself and decide whether or not I like it.
