one with administrative privilege should be able to see my request (that has been deleted) on a multi-page PDF file added to mwe package: meta.tex.stackexchange.com/users/19356/…
@egreg: I thought of you some minutes ago! We sang:
O vos omnes qui transitis per viam:

Si est dolor similis sicut dolor meus.
Attendite, universi populi, et videte dolorem meum.

@Karl'sstudents my texlive 2012 has quite a few pdf files in the tex tree, this one for example /usr/local/texlive/2012/texmf-dist/tex/context/base/status-lua.pdf
@PeterGrill I was reading your reply on \verb| | answer, in a few seconds it was redirecting to an old question. I think we should wait for few hours to delete the Q &A, i preferred this Q &A as it had good example.
If you want to have a "resume/pause"- like feature when downloading TeXLive then mirroring it on your hard drive is a good approach.
Advantages of mirroring TeXLive:
We can pause or resume the download.
We can share the raw TeX distribution for other users in our local network. As a result, we...
@Karl'sstudents I guess, I will still think this is more a question for math.sx even after you have changed the form. Even for a simple cone, you will have something like the left picture in the following:
@Karl'sstudents Package feature request do not belong on Meta or the main site. Instead simply contact the package author. I'm already aware that mwe misses a multipage PDF and planning to add one in the next release.
After playing around with the test file from showexpl, I found that when numbers=none, xleftmargin does not have any effect on verbatim. It only works when numbers=left or right. probably a bug? — ltxsunJan 15 '11 at 6:09
I think the questions says it all! :)
By TeX, I mean any derivative of TeX as long as the code is clearly a derivative of TeX, i.e. that it could belong on TeX.SX (and not pure Lua for example).
I'll give two answers myself so you see what I mean.
Your posted example runs without error although it isn't an example of the case mentioned in the title of using \input in tabularx (which should work mostly, depending on what exactly you input).
However I can't really suggest changes as it is hard to guess the intention of the code.
I make some...
@PauloCereda I'm going to have to remind myself how to check out a git repository (or whatever the git terminology is to get local copies of the files:-)
@JosephWright Yes I did it the other day for the w3c html test suite (which I had to fork first on github in that case) but since I just followed instructions line by line didn't really sink in, my mental model of source control is still somewhat svn/cvs oriented I expect:-)
@JosephWright yes I know (w3c less trusting that @PauloCereda in who they give rights to it seems:-) , just saying I managed fork/clone/commit/pull-request dance so I can probably manage to figure out the commands needed to mess up dandelion...
@JosephWright I'm not bothered really but as a matter of interest why is my answer here cw (did I click on it or did you or an automatic thing flip it to cw?) tex.stackexchange.com/questions/105670/…

@JosephWright: community board, defrost interview room, bring some muffins. :)
@percusse: sir, we need beer in the interview room. I repeat, we need beer in the interview room. Roger.
@PauloCereda Just remember who is next for the interview room after today......
@PauloCereda so do I just do git clone git@github.com:cereda/dandelion.git or do I need to first tell git(hub) that I'm me (ie my gmail login on github) if I want to get write access?

@JlDiaz i want to amke a picture of a householder transformation, where i can change alle the picture by just changing the first vector (the long story) i want to make a decotration that there is a right angle, so i need to calculate the arctan of (\y1/\x1) there
@DominicMichaelis atan2 needs x and y as separate arguments (and not only its quotient as atan) to compare the signs and determine in which quadrant the angle is
So, after 2 days of trying, I found out that when declaring a new pgf shape, \saveddimensions are not available in \savedanchors. Can I assume the same is true for \savedmacros?
@ThomasH You would save the definition (the calculation) of the \saveddimen inside of \savedanchor, so when you use the shape, you actually execute \saveddimen the first time and not while the defining the shape. This seems very messy …
I have a question about \saveddimen usage inside of a \pgfdeclareshape
command. My code is as follows:

@percusse I saw that before, but it's a bit too much trickery for my liking, as it exploits an unexpected side effect
I'm basically trying to make my life in declaring anchors, saved anchors and the backgroundpath easier by only defining once how to get the width and height of the shape and then re-using it
@Qrrbrbirlbel I declared \saveddimen{\mywidth}{\pgf@x=\pgfkeysvalueof{/pgf/minimum width}} (and analog for height) in the hope of re-using it to calculate a saved anchor at half width and half height of my shape.
So that I could 'escalate' it's complexity (taking into account inner and outer sep) gradually without having to search/replace everywhere
@ThomasH Erm, … I think I have misunderstood you before. I thought you wanted to do \savedmacro{\somemacro}{… stuff \saveddimen{\somedimen}{…}}. But you actually want to use \saveddimen inside of \somemacro, i.e.\savedmaro{\somemacro}{… \somedimen …}?
@Qrrbrbirlbel I need to use the width of my shape (which involves some calculation) a couple of times, inside \savedanchor, \anchor and \backgroundpath definitions. So I wanted to use a \savedimen to only calculate (and more importantly type) it once. But \saveddimenions are not available inside a \savedanchor declaration, so I was wondering if I can define the calculation using a \savedmacro, if I can make that available inside \savedanchor
@ThomasH I think, without a real example, one can only guess how to best solve this. The basic example, the rectangle shape only uses the southwest and the north east anchor to calculate everything (the shape is pretty basic, too). The width can be obtains by x_NE - x_SW.
@ThomasH In this answer of mine I have added anchors that lies directly on the middle of the drawn line and have opted to not save the line width but to save the anchors \linenortheast and \linesouthwest and use these to calculate all other anchors on the line. (In my own collection, there is also an addition of outer and inner anchors which lie on the inner side and the outer side of the line, disregarding what outer sep is/are.)
@Qrrbrbirlbel Yeah, I think I might be putting the cart before the horse. It seems that most people do the heavy duty / nitty gritty calculating in \savedanchor and then reuse the saved anchor in calculating other bits. I was trying to do the calculation outside and reuse it in the \savedanchor declaration
@ThomasH I’m happy to take a look at it as soon it is posted. Make a good MWE and distract the real PGF experts, otherwise they will probably be faster. ;)
In the following MWE, I declare a new shape myshape. In several instances, I plan to use a dimension that is calculated from different pgf keys (\my@width). One of these instances includes the declaration of the saved anchor \base. At the moment, I have to duplicate the code that calculated this ...
I just installed the vim latex-suite plugin. Whenever I type empty brackets, parentheses, or braces, I get an extra pair of them, and I am moved to the middle of the new pair and put into insert mode.
i.e. after typing
{}
I get
{}{}
with the cursor between the second pair of empty brace...
@ThomasH The \pgf@sh@savedpoints contains the code \def \my@height {71.13188pt}\def \my@width {16.09285pt} (for the second node), and in fact, the following works:
@percusse Thanks for the awesomely patient answer. I read Andrew's answer several times before that but every time my eyes see an \expand or edef my brain seems to switch off
All I took from his answer was that you can hack your way around the problem by making sure there's no new assignments between two \saveddimen declarations. Instead, I wanted to do it the 'right' way ...
@Qrrbrbirlbel But I need a saved anchor, no? I do have the textsize one, but that's an afterthought, since I don't plan the node to contain any text really.
I was hoping to draw the shape from the`\base` anchor upwards. That is, if the node is placed at (0,0), I wanted the \base anchor to be at (0,0) rather than the center of the shape
@Qrrbrbirlbel That would be a worthy answer to the question I posted as well, if you want to add it. But it seems from your and @percusse's answer that what I am trying to do is not how it should be done, since both approaches resort to 'hackery' of some form or another :(
@ThomasH Nope, you do not need a saved anchor, at least not with the shape definition you provided. You can define base entirely from \my@width and \pgf@x=0pt (which is what you wanted all along).
(You can of course also define two anchors and calculate the width and the height from that. In fact, if you do not use \my@width and \my@length anymore, I would define only the anchors.)
@Qrrbrbirlbel I see, well, tbh, I've tried so many different approaches trying to get it to work, I'm not sure what's needed anymore (head cold doesn't help)
For compatibility reasons I would also define the anchors center, west, east, north, south. (Important for the positioning library.) Maybe base * and mid *, too.
Though the pgf manual says: In order to define a new shape, you must provide: • a shape name, • code for computing the saved anchors and saved dimensions, • code for computing anchor positions in terms of the saved anchors,
Then again, it does say "code for saved anchors" not "saved anchors"
Yes, I was getting to those, though if I define east, west and others that don't sit on actual lines, I'm probably better off inheriting from rectangle and save myself the grief. I don't think there's any anchors that wouldn't be covered by it
@Qrrbrbirlbel do you happen to know which part of it is placed on the actual coordinate? I would like that to be the bottom of my shape (as currently defined by the \base anchor)
1. saved anchor + \pgf@sh@savedpoints; 2. without any saved anchor; 3. without saved dimen.
(0,0) in the local node coordinate system (i.e. \pgf@x=0pt and \pgf@y=0pt) is at the baseline of the node text (the left one). (I think, let me check.)
@Qrrbrbirlbel Yes, the centerpoint lies on .5\wd and .5\ht of the \pgfnodeparttextbox.
So the preferred approach would be then to "compute from first principles" in any \saved... definition, i.e. use only commands already established by pgf?
