I am a Java beginner with a question about the operation of the Digitalclock.java example in Netbeans 8.0.2
I want to alter the display to show only Hours and Minutes and change the color. I have found within the code a way to eliminate the display of the Seconds digits and change the color. What I can't do is get rid of the ":" or center the display.
1) Where is the ":" being generated from?
2) How would I center the display?
Thank you,
The colon ":" in this case is not an actual character rather it is being generated by using multiple instances of the java circle class and can be found in line 114 - 117 of the DigitalClock.java file. Centering the the new four digit clock can be accomplished by changing the clock.setLayoutX at line 78. – Six just now edit

I need to indent some math stuff in the \details section of my .Rd documentation to enhance its readability. I am using mathjaxr. Is there any way to indent without installing roxygen2 or similar?
The math stuff is inline, so simply setting to display using \mjdeqn won't solve this.
I seem to have a reasonable "cheating" work around for indenting the first line using mathjaxr, at least for the PDF and HTML output.
We need to do two things:
Use the mathjax/LaTeX phantom command. phantom works by making a box of the size necessary to type-set whatever its argument is, but without actually type-setting anything in the box. For my purposes, if I want to indent, say, about 2 characters wide, I would start the line with a \mjeqn{\phantom{22}}{ } and following with my actual text, possibly including actual mathy bits. If I want an indent of, say, roughly 4 characters wide, I might use \mjeqn{\phantom{2222}}{ }.
Because mathjaxr has a problem with tacking on unsolicited new lines when starting a line with mjeqn, we need to prefix the use of phantom in 1 above with an empty bit of something non-mathjaxr-ish like \emph{}.
Putting it all together, I can indent by about 2 characters using something like this:
\emph{}\mjeqn{\phantom{22}}Here beginneth mine indented line…
I need to explore whether the { } business actually indents for ASCII output, or whether I might accomplish that using or some such.
I've created a little Xmobar status indicator for https://complice.co. Inspired by the agnoster Zsh theme, I used some box-drawing characters to try to put triangle-like ends on the end of the status bar. But they aren't aligning correctly, as shown here:
The triangle is too small, leaving a lip at the bottom. It annoys me that it's not pixel-perfect. Does anyone have any insight into why it isn't sized correctly? I've never used box-drawing characters and couldn't find any documentation on the specific ones I'm using (\ue0b2 and \ue0b0) - any links would be appreciated.
I use a script to generate the text. The important part is here where I use the box-drawing characters: https://github.com/d4hines/beth/blob/master/scripts/complice#L38
And the Xmobar config: https://github.com/d4hines/beth/blob/master/flake.nix#L249-L265
Main question
I would like to add powerline characters at the start and at the end of the selected completion, like this:
Started the completion menu by inserting c and pressing the TAB key.
Moved right in the completion menu by pressing the right arrow key.
Moved down in the completion menu by pressing the down arrow key.
Is there any way to make zsh look/behave like in the pictures?
Note
Added powerline triangle + blank character at the beginning and blank character + powerline triangle at the end should somehow be accounted when columns are created to keep the alignment correct.
Bonus
Add 2 blanks at the beginning of every completion in the list, so that when the completion is selected it doesn't look like the text was moved to the right.
( This issue can be seen by comparing the completion with and without the selection. )
Alternative question
In case that previously explained behavior is impossible to get without changing the zsh source code, is it at least possible to add powerline triangle only at the end of the selected completion?
My unsuccessful attempts
I have tried using the lc, rc, and ec variables in the list-colors style but that didn't help:
Completion list was badly aligned and it created all kinds of visual problems.
Symbols were inserted in all elements of the completion list, not just the selected one.
I have also tried using the ma variable, but I couldn't properly insert a character at the beginning:
The variable expects only a number that represents a color and it is probably wrapped in some escape sequences, so the output did not look as expected.
This works for me.
zstyle ":completion:*:default" list-colors ${(s.:.)LS_COLORS} "ma=48;5;153;1"
Uses my LS_COLORS and then ma sets the background of my selection to bold and color 153 from https://jonasjacek.github.io/colors/.

In this example, prettytable.py can not display properly chinese ambiguous width of character · in 买买提江·阿布拉 , the character has ambiguous width. How to fix the bug in prettytable.py?
I have add two lines in def _char_block_width(char) of prettytable.py, but the problem still remains.
if char == 0xb7:
return 2
I have solved it, the file prettytable.py should be installed in my computer d:\python33\Lib\site-packagesdirectly not in as the form of d:\python33\Lib\site-packages\prettytable\prettytable.py
There are many chinese character with ambiguous width, it is stupid for us to add two lines such as the following to fix the bug, if there are 50 ambiguous character,100 lines will be added in the prettytable.py, is there a simple way to do that? Just fix some lines to treat all the ambiguous character?
if char == 0xb7:
return 2
The issue you're running into has to do with the dot character in the incorrectly padded line of your Python output. The dot is Unicode code point U+00B7 · middle dot. This character is considered to have an "ambiguous" width, as it is a narrow character in most non-East-Asian fonts, but is rendered a full-width in most Asian ones. Without context, a program can't tell how wide it will appear on the screen. Unfortunately, Python's Unicode system doesn't appear to have any way to provide that context.
One fix might be to replace the offending dot with one that has an unambiguous width, such as U+30FB katakana middle dot (which is always full width). This way the padding logic will be able to recognize that extra space is needed for that line.
Another solution could be to set your console to use a font with more Western treatment of the middle dot character, rather than the current one that follows the East-Asian style of rendering of it as full-width. This will mean that the existing padding is correct. Your output from R clearly uses a different font that the Python output does, and its font renders the dot as half-width.
How to convert all color code #XXYYZZ to shorter 3 character version #XYZ of whole css file?
You can convert to the shorter 3-character version only colors expressed this way: #RRGGBB where the first and the second characters are the same, the third and fourth characters are the same and the fifth and sixth characters are the same.
So: #CC00DD can be shortened to #C0D while #CC01DD cannot.
A quick way to shorten all the possible colors in a CSS file is to open the file with an editor supporting regular expressions (for example kwrite or kate on linux) and replace (ignoring case) the following regular expression:
#([0-9A-F])\1([0-9A-F])\2([0-9A-F])\3
with this substitution text:
#\1\2\3
Tested with kate.
Otherwise you can use this tool where, if you only need to compress color codes, you can uncheck all the options except the "Compress color codes where possible".
If you are just interested in minimizing the download size for your CSS file, you might use one of the many CSS compressors available (such as this one). And be sure to do the same with your javascript files while you are at it.
You can only shorten CSS colour codes to a 3 character version if they take the form
#XXYYZZ
Then they can be abbreviated
#XYZ
There are only 216 different codes which meet this requirement.
