@JosephWright @AnyMod Could somebody unfreeze the Forest chat room again, please? chat.stackexchange.com/transcript/30992
@AlanMunn Are you around? I have a Forest question ...
0
Q: How can I upgrade Forest code for={Lu}{} so that my diagram compiles with current Forest?

cfrI created the following diagram using Forest version 1: \documentclass[tikz,border=10pt]{standalone} \usepackage{forest-1}% forest v.1 \begin{document} \begin{forest} for tree={ font=\sffamily\scriptsize, line width=1pt, draw, anchor=west, child anchor=west, parent ...

tikz-pgf errors trees forest
@AlanMunn I must surely be missing something blindingly obvious ....
Alan Munn

@cfr Sorry, but this is out of my range of forest knowledge, at least without doing some serious messing around (which I don't have time for right now, unfortunately). As a linguist my needs are too simple (binary branching trees with some arrows occasionally). :)

@JosephWright I'm so glad I'm not the only person using svn. I really, really tried to sit down and understand the basics of git last week so I could put the workshop code on GitHub. But I gave up. It is still in my personal svn repo and now on OverLeaf. Subversion was not difficult to start to learn. Git is just a mystery.
@AlanMunn I thought you'd say that ;(. I'm really puzzled by the effect of the compat=1.0-all key. How the hell does that happen to it?!

Hello,

I am using scrbook, and I would be grateful if anyone could tell me how to make the chapter prefix be "CHAPTER 1: <title>" on the same line of title without line break.

@cfr I've said before that I find the Git CLI) user interface less friendly than Mercurial, though one gets used to it
@cfr I probably use Git in a rather 'SVN like' way: the most complex set up I have is for siunitx, where I have two branches (at present rather divergent, normally not that different). I do like having the log data locally: makes looking back over things on the train easy!
@cfr I'm sure you've seen various 'SVN <-> Git' guides. I suppose I routinely use perhaps half a dozen commands

Is there a place where one can be volunteer for Tikz ?
Open sources may be
3 hours per week will be good for me.
I'm thinking to pick books and draw its graphs to reinforce my skills.

@CroCo most likely place is here, as a question.
Paulo Cereda
Paulo Cereda
@CroCo Ah I see, sorry for the confusion. :) My suggestion would be: take a look at some TikZ efforts, like existing libraries or packages that heavily rely on it. Surely the authors could benefit from contributed code. Contact them or simply experiment changes and improvements. You could also work on your own personal projects, so it's a nice start!
CroCo

I'm having some problems with encoding for our company-class. Since we only write in norwegian, we need UTF-8-support, therefore, I wanted to add '\RequirePackage[utf8]{inputenc}` as the first package loaded by the class, but somehow this doesn't work at all. If I don't add the line, and only use \usepackage[utf8]{inputenc} in the document, it works like I would expect it to. If I add both, it doesn't work.
By "doesn't work" I mean that the utf-8-support is broken. Should I create a question for this?
daleif
daleif
15:52
@RunarTrollet We might at least need to see more code. In our University letter class, I ended up removing inputenc, that is the users job not mine. Also you don't know if the user is using pdflatex, xelatex, lualatex where forcing inputenc might be problematic. I just ended up writing (and requesting others do the same in their department config files for the class) special letters as TeX codes, aka ascii. Then it always works (almost, some font packages forget to define say \o)
You get into the same problems if you try to force babel (I also left that one out)
wilx
wilx
@RunarTrollet MWE?
I guess creating a question is not out of the question!
cfr
cfr
16:19
@wilx The thing is, I'm not sure it would even make sense for me to use git instead of svn. So I was trying to figure out how to move some things under svn to git without losing their history and without changing my svn repo to git. [My svn repo is local on my machine and it is used exclusively by me on two machines, which both hold copies of it. All of the user guides assume a more standard case and assume source code is the issue, multiple users etc.] Besides, CLI is crucial.
David Carlisle
David Carlisle
@RunarTrollet it should work although to be honest it's better to declare it in the document. the file encoding is a property of (each) file not a property of the class.
cfr
cfr
@JosephWright My svn repo is local anyway. I just have a copy on one or two machines and back ups on external disk and in the cloud.
David Carlisle
David Carlisle
@cfr we use svn exclusively at work, for a repository that does have a clear master copy git as a source code control doesn't really have a lot over svn I'd say, but for open projects where you want to expose the history and issue tracker etc github is really one of the better web interfaces so (especially since google killed googlecode) I've been tending to use git(hub) for personal projects,site)
Joseph Wright
Joseph Wright
16:38
@cfr there are various tools for creating Git versions of SVN histories, either at the 'user end' or from the server (see SubGit, for example, which we use for LaTeX3)
@DavidCarlisle Well it depends on your workflow but I do know what you mean (depends whether you like the 'lots of branches' approach)
David Carlisle
David Carlisle
16:56
@JosephWright we have a few dozen branches in svn is that lots? (versions and point versions and individual developers experimental branches, they all seem to merge back OK when required (better than cvs)
@JosephWright do I remember you saying you were looking again at what we need to do for tu encoding, probably we should do it since it's nearly Christmas, so I'm told:-)
Joseph Wright
Joseph Wright
@DavidCarlisle Yes ;)
@DavidCarlisle Those are 'permanent-ish' branches I guess? That works OK with SVN (though I personally do prefer the way Git only shows one branch at a time): I was thinking of the 'you branch for development of a feature or similar' way that various people suggest working, which is less well supported by SVN (for example, everyone has to have the branches in SVN rather than being able to branch locally)
@DavidCarlisle I'm not going to try to sell any particular version control system to anyone :) As you say, the big plus for git for open source things is the GitHub interface rather than anything else
@DavidCarlisle I think my favourite Git thing is the log tool, which works better than the SVN, at least for me (could be a Windows thing ...)
David Carlisle
David Carlisle
17:14
@JosephWright I tend to use svn log > foo.txt then look in emacs:-)

17:33
@JosephWright I use branches. I didn't know svn could show more than one at a time. But maybe I don't understand what you mean.
@DavidCarlisle GitHub is really the attraction. But I like subversion for documents and I like have my custom code under the same vcs. subversion is rather painfully slow, at least with a local file-system repo. But I can live with that. I guess there is probably some maintenance thing I don't know to do which makes it slow. I just thought if I could put the code for the workshop on GitHub, it would work quite nicely. The original is there and OverLeaf now integrates with GitHub.

Hello everyone!
Do you know if pdflatex, xelatex or lualatex ever write to stderr when there wasn't really an error?
I noticed that pdflatex from MiKTeX will write to stderr if it has encountered some serious error. The output to stderr is relatively short and informative (unlike the output to stdout or a LaTeX log file, which typically contain 90% irrelevant information for most debugging we do).
Is this usually the case?
Joseph Wright
Joseph Wright
18:13
@cfr With SVN if you check out the 'top level' you end up with each branch as a separate directory within in. In contrast, a Git checkout only ever shows one branch so there's not this (to me) issue: I know @DavidCarlisle feels it's fine :)
@cfr I'm sure if you can give an example of your workflow I can 'translate' (I use both SVN and Git reasonably routinely, though can't claim to be a real expert in either!)

@JosephWright v.v Why is that five lines instead of one?

@Canageek So each message is clearly delineated
@Canageek New document commands change the semantics of LaTeX => important

@JosephWright I wonder how much faster this would compile if it didn't have to write all this out command line?

19:29
@Canageek Very little
Canageek

@JosephWright (I once wrote a program that took so long to run I thought it was in an infinite loop. Once I turned off almost all the output it finished as soon as I ran it)
Joseph Wright
Joseph Wright
@Canageek Unless you \tracingall beamer you are likely safe!
Canageek
Canageek
@JosephWright Still, it does a lot to hide imporant messages like 'option depricated'
@JosephWright Would be nice to have a 'user facing' message option.
Or a 'only if this is unexpected/wrong'
a .logall and a .logbad or such
.all.log .bad.log?
Joseph Wright

@Canageek For the LaTeX3 warnings there is a mechanism to turn them off 
\documentclass{article}

\ExplSyntaxOff

Hi everyone,

This is maybe a naive question for koma-script, but I totally forget how to do it. I did prefix "CHAPTER" to chapter entries in toc using

\renewcommand*{\addchaptertocentry}[2]{%
\addtocentrydefault{chapter}{\chapapp\nobreakspace#1:}{#2}%
}

However, it also affects lof and lot titles in toc. So, is there any way to confine this manipulation to normal chapters only?

@Canageek When NFSS was written it was like entering a new universe. Just remember that prior to it it was like cars from Ford: you could have any color as long is it was black. So understanding what got changed and how was an important feature (still is if things go wrong though fortunately that is not happening often any longer.
it is again in the world of unicode and unicode fonts as there it is again luck if things work end-to-end ... but unfortunately for this NFSS tracing doesn#t really help you
Canageek
Canageek
@FrankMittelbach So it made a lot of sense at the time, even if now it is mostly visual overload?
Thanks
Frank Mittelbach
Frank Mittelbach
@Canageek well most of it is only log, so not that much visual (unless you are one of those people that read the .log file
the problem this these things is that if you turn them off completely then you never get to see them if somebody is in trouble (which is why I tend to keep info in the .log file)
Canageek
Canageek
@FrankMittelbach Yeah, I watch for compile errors and messages from packages as it compiles. How else would I see all the packages telling me to update, or the overfull hboxes? >.>
It is so odd how many papers report using Shelx97 to solve their structures. Imagine if people refused to update LaTeX since 1997. (Please tell me they don't do that)
Frank Mittelbach

@Canageek 1997 is quite new really ... I have seen older installations :-)
Canageek

@FrankMittelbach In 1997 I think we had a Windows 3.1 computer with a 386 in it. We MIGHT have gotten a used 486 running Windows 95 by then that never worked right.

Many thanks. I came across a weird behavior when using \appendix command.

I found that all prefixes of chapter entries in ToC have an additional dot. For example, <CHAPTER 1: title> has become <CHAPTER1:. title>. This behavior only shows up when using \appendix command.

How can I fix this?

@Canageek Shelx97 was the standard for a long time: it's when you see Shelx76 you need to worry! (We had some data recently unreported but run about 20 years ago so done with 76: luckily someone had kept the crystals so we could re-run!)

@JosephWright It is a good program: I use it for some things. I prefer to solve crystals to start with in ShelxLE, but often fiddle with the disoorder in OLEX2. I don't like how much it mucks about with my res file though. I've got those comments in place for a reason, stop shoving them to the top of the file!
Very good for doing hfix and difx and such though, far easier.
@JosephWright Yeah, but when a paper comes out in 2016 using 97? o.0 (That said, I bet all the bugs are known by now, unlike 2016/6....)

David Carlisle
David Carlisle
@Canageek so why are you using a typesetting engine hardly changed since 1993?
cfr
cfr
@JosephWright Oh, I don't think I ever check out the top-level. I have a repo on another logical volume of my disk in a directory svn. The top-level has sub-directories according to purpose e.g. teaching, work, texmf etc. (OK, not necessarily in English, but those are the kinds of meanings.) Each of those has branches, tags and trunk as is standard. Each of the top-level directories corresponds to some working directory in my home. ...
If I branch, I check out the bit that I care about into the relevant sub-directory of my working copy. Or, rather, I switch the existing sub-directory to the relevant branch. So I work with a mixed working copy (I can't remember the technical term). Usually, branches correspond to alternative versions of papers e.g. a version which cuts out all the stuff about Y to focus on X. I tag journal submissions. I should tag or branch modules, but I don't. I just create another sub-directory in trunk.
Canageek
Canageek
@DavidCarlisle It is heavily changed! It has SIunitx, chemacros, etc.
David Carlisle
David Carlisle
22:01
@Canageek has it, I never noticed:-) (but I meant the executable, really)
Canageek

@DavidCarlisle Admittedly, it could use an upgrade to account for the fact that modern computers have GB of memory.
@DavidCarlisle Well, the second I can publish in LuaLaTeX and use OTF fonts....

The repo is synchronised between 2 machines, if I am currently using 2, or kept on 1 otherwise. Then it is backed up to hard disk and the cloud. I sync either using the cloud or using unison usually. That's really it. I then make heavy use of svn-prov and svn-multi in documents/classes etc. @JosephWright
Joseph Wright
Joseph Wright
@cfr If you use SVN properties then Git is not for you: there's a philosophical position for Git that things like revision number don't 'belong' in sources
@cfr From a Git POV they'd normally I think be separate repos: hard to see that there's a single history
cfr
cfr
@JosephWright How are you meant to keep track of things, then?
@JosephWright That would probably be better, but doesn't work with svn.
Joseph Wright
Joseph Wright
@cfr Well Git, like other version control systems, is primarily aimed at code with a 'compilation' step. So if you want the hash (there are no revision numbers in Git) in your 'output', you script this to be added during the 'build' phase.
cfr
cfr
22:08
@JosephWright And, yes, I use svn properties heavily, including the automatic properties which I rely on a lot. Especially for research so I can tell whether printed copy is current or note which revision I'm sending in an email.
Joseph Wright
Joseph Wright
@cfr For say a release of something one normally expects to mark it as such: a human intervention step
cfr
cfr
@JosephWright Maybe svn is just better for documents? Even a .cls doesn't really seem to fit that model.
Joseph Wright
Joseph Wright
@cfr One can arrange to add the Git hash to a PDF typeset with LaTeX (see gitinfo, etc.), but not to the source itself. The same is more-or-less true of all DCVS systems (we had some 'fun' with beamer for a while as my co-maintainer set up Mercurial in an SVN-like way)
cfr
cfr
@JosephWright I don't think I'd like that :(.
Joseph Wright
Joseph Wright
@cfr One would normally still expect to have 'release versions' (or at least I would, as I'd have the source as a .dtx and need to build/extract for release)
@cfr Don't use a DCVS, then: it's at-best an add-on concept (Mercurial) or simply not available at all (Git) (I've not tried the same thing in Bazaar)
cfr
cfr
22:13
@JosephWright I just tag releases of prooftrees, for example. Or use a branch for a substantial change I'm experimenting with. So I have a pgfmath branch and 0.3 and 0.4 tags. (I didn't used to keep code in svn.)
@JosephWright I was only really considering using it for the workshops on LaTeX. I could probably live without properties there. But those are in sub-directories of sub-directories of ... so I'd need a way to extract them, preferably with their histories, and put them in git. And I'd ideally keep them in a sub-directory of my svn working copy (but this should be fine as I can just tell svn to ignore them). But the instructions I found seemed designed for whole repos and I couldn't figure it out.
@Canageek Because it doesn't know you are not me. I frequently look at the log precisely to check stuff about fonts.
Canageek
Canageek
@cfr Hummm. Still wish there was someway to highlight messages normal humans care about, like "this package is depreciated", "hey idiot, this line extends into the margin" and "this font you are trying to use doesn't exist as you got the order of them backwards"
