My current vim setup sticks the first line all the way to the top, so that all the characters are touching the edge. Is there a way to to add a small amount of padding to the top so that the text doesn't touch the top?
Currently it looks as like:

I have a variable-width container (screen width) and fixed left and right margins. Remaining area gives me a constraint for maximum text width, where I'm placing text of variable content (multiple languages). I want text to fit into that width without truncation, wrapping if needed. Text is relatively short - it may fit into single line, likely to fit into 2 lines and will fit into 3 lines for sure.
I want to avoid cases like (2) - where text wraps into long and a short line. It does not look nice. Instead I would like it to wrap more evenly, like in case (3).
For the demo purposes I've hardcoded hand-picked margins, but I want solution to work automatically for any text content and any container width.
Is it achievable using built-in Flutter widgets, or I need to implement something custom, similar to https://pub.dartlang.org/packages/auto_size_text?
I wanted to allow the Emacs cursor to move around freely outside of actual text (similar to virtualedit=all in Vim).
"Oh," I thought, "I'll just keep track of a virtual cursor and draw it to the screen myself."
But it turns out the actual native C drawing routines (such as draw_glyphs) seem to refer back to the buffer contents to decide what to draw (I could be wrong though).
My next idea was to make a giant overlay of all spaces so I'd have complete freedom where to put stuff. But an overlay only goes over ranges of actual text, so again, this does not seem to give me what I'm looking for.
Is this a reasonable goal without hacking the C code?
I believe the writeable area of a window is intrinsically limited to the buffer with which it is associated, i.e. you have to draw in an area where buffer content exists.
(One example of this limitation is the impossibility of drawing a vertical guide line in the 80th column to help the user identify long lines; currently the best possible implementation of such a feature is to highlight the "overflow" of each too-long line.)
You can do the same as what artist-mode does without adding spaces to the buffer:
when trying to place the cursor after the end of the line, just use an overlay with an after-string property which adds the spaces in the display without modifying the buffer.
Have a look at "artist-mode" (M-xartist-modeRET) - it allows you to draw in Emacs.
From the function documentation: "Artist lets you draw lines, squares, rectangles and poly-lines, ellipses and circles with your mouse and/or keyboard."
You can look at popup.el from the auto-complete package, which can pop up tooltips and menus and such at any position, including positions outside the contents of the buffer. Maybe that will show you how you can do it.
I have a view that draws multicolored text inside UITableViewCell. To draw multicolored text I'm using NSAttributedString However, I would like to make it so that if the text is too long to fit into the view, the last visible line is truncated to display an ellipsis at its end.
Obviously this is very easy to do when drawing only a single line, as you can just set
kCTLineBreakByTruncatingTail for the line break mode of the paragraph style. The problem is that I want my text to wrap to fill the rectangle, and then only have the last line truncated with an ellipsis - setting the line break mode confines the whole text to one line.
Does anybody have any ideas of how I would go about this?
Many thanks in advance for any suggestions,
JC.
Create your CTFrame from your CTFrameSetter with the rectangle of your UITableViewCell. Then, you can get all the CTLines of your CTFrame and determine when they will cut off. To swap out the ellipsis, you could keep that drawn with a separate CTFrame and draw it over the overflowing text on the last line.
You can find working code here: https://stackoverflow.com/a/14612598/473067
It's a similar approach to what Heath suggested. But then all wrapped up in a shiny package.
Well, to activate text truncating in UILabel, you should re-set lineBreakMode parameter to NSLineBreakByTruncatingTail after setting attributedText.
textLabel.attributedText = attributedText;
textLabel.lineBreakMode = NSLineBreakByTruncatingTail;
Ok, I am beat. I tried a few things but I am unable to make this happen. I need some help now.
I want to be able to have some text and picture side by side (only one line, thus no need for wrapping or other fun. The picture is small enough to fit in a text line):
This is a text <temp.jpg placed center to the textline>
Problem is, when I use
This is a text \includegraphics{temp.jpg}
the pictures baseline is alligned with the text baseline. I want the picture (vertical) center to be aligned with the text baseline. How can I make this possible?
This is a text $\vcenter{\hbox{\includegraphics{temp.jpg}}}$
It sounds like you want \raisebox (see the raisebox section of the LaTeX wikibook), with a negative argument. Use dimensions ex (the notional height of an 'x' in the current font) or \baselineskip (the size between text baselines) as your units.
If you want to do more complicated things, such as move the graphics box down by half its height, you can, but it gets fiddly. If the graphic size isn't unpredictable, you're probably better off tuning this by hand anyway.
In my opinion, most simple answer \raisebox{-0.5\totalheight}{<your graphic here>}
This is a text \raisebox{-0.5\totalheight}{\includegraphics{temp.jpg}}
Explanation:
\raisebox moves vertically the whole text/picture given as second argument. The first argument is the vertical shift as a length. This command provides the length \totalheight which is, self-explanatory, the height of the whole text/picture that you want to raise. The factor -0.5 lowers exactly at the half of the length(as the question demands). For aesthetic adjustments just modify the factor's value.
By the way, with this method there is no need to get into math mode as in #AlexeiMalistov answer, and no need of double command \vcenter + \hbox
I'm using LaTeX and I would like to have vertical rule along left side of page, topmargin to bottommargin, 0.5in from the left edge of the page. I want this on every page, so I assume that means it must somehow be tied to the header or the footer?
I've made no progress at all, so I need help with (1) making the full-length rule itself and (2) making it happen automatically on every page of the document.
Can someone tell me how to do that?
I got a working answer to my question on the Latex Community forum: http://www.latex-community.org/forum/viewtopic.php?f=5&t=9072&p=34877#p34877
The answer I got uses the 'Background' package and this code:
\documentclass{article}
\usepackage{background}
\usepackage{lipsum}% just to generate filler text for the example
\SetBgScale{1}
\SetBgAngle{0}
\SetBgColor{black}
\SetBgContents{\rule{.4pt}{\paperheight}}
\SetBgHshift{-9cm}
\begin{document}
\lipsum[1-90]
\end{document}
Works great and was easy to adjust to put one vrule in left margin area and one in the right margin area.
There could be a LaTeX package to do this for you, but I'm more of a TeX person, so I tried to come up with a TeX solution (not always the best idea to mix plain TeX with LaTeX but I think I have it working).
Try this. Box 255 is the box register that TeX places the page contents into before the page is output. What I've done is taken the existing output routine, and changed it to insert into box 255: a 0-height, 0-width infinitely shrinkable-but-overflowing set of boxes containing a rule that is the height of the page, 0.4pt thick and with any luck, half an inch away into the left. The existing contents of box 255 is then added after this rule. Then I call the previous output routine which outputs the page (which now includes a rule), and also the headers and footers.
\newtoks\oldoutput
\oldoutput=\expandafter{\the\output}%
\output{%
\setbox255\vbox to 0pt{%
\hbox to 0pt{%
\vsize\ht255%
\vbox to \ht255{%
\vss
\hbox to -0.5in{%
\hss
\vrule height \ht255 width 0.4pt%
}%
}\hss
}\vss
\box255%
}%
\the\oldoutput
}%
Put it before your \begin{document} command. This might not solve your problem completely, but hopefully it should get you started. Here's a great page for learning about TeX primitives and built-in things.
Have a look at the eso-pic package. From memory, what you want would look like this:
\AddToShipoutPicture{%
\setlength\unitlength{1in}%
\AtPageUpperLeft{%
\put(0.5,\topmargin){\vrule width .5pt height \textheight}%
}%
}
It's not clear in your question if you want the line to span the text area or the whole paper height. Depending on the case, you have to replace \topmargin and \textheight by the correct values, either 0pt or whatever your top margin is, or by \paperheight. See the geometry package if you don't already use it for how to control those dimensions.
