I'm using Codemirror in an app. Has anyone found a way to make it uses spaces when using tab? When I press enter to go to a new line it uses spaces. However, if I backspace to the beginning of the line, and use a tab instead, it inserts it as a tab instead of 2 or 4 spaces or whatever I have it set to. Then, when I view the rendered view, my code has like 8 spaces for indentations in the areas where I used the tab key. Is there some option or way to convert actual tabs to spaces in Codemirror?
I'm also using the codemirror-rails gem, which may not be as up-to-date as the actual Codemirror version.
I would override the default tab key functionality and replace it with this function.
Add this to your Codemirror configurations.
extraKeys: {
"Tab": function(cm){
cm.replaceSelection(" " , "end");
}
}

I would like to ensure that names in a multi-line copyright string on the launch screen do not get split by line breaks on different devices. Inside a view controller with a UILabel outlet textLabel, the escape sequence "\u{00a0}" works programmatically:
textLabel.text = "Lots of text before... Firstname\u{00a0}Lastname... and after."
It displays the string with the escape sequence replaced by a space and the words either side always appear on the same line.
However, I can't get it work by putting it in as the value in a UILabel in Interface Builder - either in LaunchScreen or any other View Controller. It just displays the string with the codes left as typed. I've tried all the various combinations of \u, \U, \\u, \\U, \x+, etc. suggested in several SO questions to no avail. I think intervening in the display of the launch screen programmatically is impossible.
Have I missed something?
Don't use \u{00a0} in the text you enter into the storyboard. Enter an actual non-breaking space. The easiest way is to type ⌥-space (option-space).
If you ever need to enter any other special characters, another option is to use the standard Character Viewer. Select Emoji & Symbols from the Edit menu to bring up the Character Viewer. Then find the desired character that you wish to put in a label. You can do this in Swift code as well instead of typing cryptic Unicode escape sequences into your strings.
I'm using Brackets editor http://brackets.io/ and I'd like to change behavior when I click TAB key it will put 4 SPACEs instead and also I'd like to change amount of spaces added.
Is it possible to do this adjustment?
In the lower right corner of the editor, you'll see text saying Spaces: 4 or the like.
You can click Spaces (or Tab) to toggle between those and click the number to change it.
I want my files to be saved as 4 spaces per tab. However, when navigating through the file, I want 4 spaces to be navigated over as if it was a tab. How do I do that?
Set tab_size equal to 4.
// The number of spaces a tab is considered equal to
"tab_size": 4,`
and set to true
// Set to true to insert spaces when tab is pressed
"translate_tabs_to_spaces": false,
I think there's no way to do that without plugins.
I personally use custom binding for navigation and almost never use the arrows, and use command/ctrl/alt + left/right arrows to navigate by words, when you'll get used to this, you'll become very productive. You can then ctrl+right arrow to get from the beginning of the line to the first indented character.
I'm trying to override the default behavior of list items and buttons in jQuery Mobile, which has text which doesn't fit on one line as hidden overflow.
If you view this on a skinny browser window or iPhone you'll see what I mean: http://m.gizmag.com
I'd like to be able to wrap the text in the h3 and p tags of each list item onto new lines.
Thanks in advance!
Try setting a style of white-space:normal for the elements.
I just did this with an anchor (<a>) element inside a jQuery Mobile listview-styled li, and it worked to wrap the text as I expected. I used Chrome's developer tools to determine where the CSS attributes were coming from and interactively changed them to make it work the way I wanted.

If feasible, enclosing it inside a <div> will also make it wrap. (But finding the affected element and declaring white-space:normal is the more proper solution)

Is there any way to do this in the Powerbuilder properties window for a datawindow's textbox?
That kind of depends on how you define "textbox", but in general the only way to mix normal and superscript text is with a richtext control. In PB 11.5, you can even use richtext as a column style.
Good luck,
Terry.
Yes. For the text control, you must select a font that has superscript characters (Arial does).
Go into the Windows Character Map (usually in the start menu under Accessories->System Tools) and select your font.
Then go to the superscript character that you want to place in your text control. Click it and then click the Select button to place it down in the character map text box.
Then click the Copy button.
Now you can return to PowerBuilder and paste this value into the properties window text area.
As long as the same font is selected for the DataWindow control as was selected in the character map it should show as your superscript character.
This same techinque can be done to include any of the Wingding type characters as well.
We ended up using two separate text fields. It's a butt-ugly solution, but it works. The superscript field has a smaller font and is nudged a little higher up.
I think newer PB versions support superscripts.
Thanks for the help.

If you go to the character map - when you select your character it will show the keys to enter this character on the bottom right of the window.
Example : in Arial font - the ® (registered) mark is Alt + 0174
To enter these, turn your numlock on, hold the alt key down, and type 0 1 7 & 4 then let up on the alt key. You have to use the number keys on the number pad to do this the ones on the top of the keyboard dont work.
You can then enter your characters directly or do something like this :
ls_key = '®'
Actually I stumbled across a simpler solution. I copied and pasted a portion of the text from a pdf into the text property of a datawindow text contol. The superscript character simply pasted in. So I'm guessing that Dougman's solution would work too.
Example:
"™Trademark used under..."
Note: I'm using PB 9.0.1
Thanks for all the help,
