I have successfully created a tcl text object and filled it with text.
focus .textpath sets the focus, but pressing an arrow takes me to the end of the text.
how do I ensure the insertion point is at the beginning of the text without user intervention?
The insertion point is the insert mark, which defaults to having right gravity (so text inserted at the point where the mark is goes to the left of it).
To move a mark programmatically, use the mark set method:
$txt mark set $mark $position
The $position can be any valid text location descriptor, including 1.0 for the start of the text (it looks like a floating point number but isn't; it's $line.$char), end for the end, 1.end for the end of the first line, etc.
In your case, to move the insertion position to the start, do this:
$txt mark set insert 1.0

If I want to delete few lines of text in most of text editors, not touching some words on the bottom line and the whole upper line, I put cursor on the bottom row leaving all unnecessary words to the left of the cursor. Then I select few lines vertically by holding Shift + ↑. I stop on upper row and get some selection: part below + right part of the upper row:
In this example I want to get rid of if word and an empty space between the function header and the code, not touching the function header (even hough let will stick to the opening bracket {).
Normally (not in Xcode) I would still hold Shift and will press cmd + ➝ to deselect the right (selected) part or the top row.
Result will be like this:
I can simply press Delete and job is done.
However, in Xcode such shortcut usage makes bottom row fully selected (till the right) and not changes upper row selection:
Same thing happens if you select from top to bottom and you need to remove extra selection from the bottom line.
I tried to rebind shortcuts in Preferences but didn't find a solution.
This example is very particular and maybe not the best, however I face such selection problems only in Xcode and have to use mouse which is not handy.
This is a rather old question, but what you want is fairly simple to achieve. If your cursor is between the if and the let, you would only need to press option-shift-left arrow twice. The first time, it would select the if and the leading tabs, and the second would select the empty line.
How do I shift a set of lines one space to the right within a text editor?
If I wanted to shift a set of lines several spaces to the right, I would perform:
selected text + Tab
However, I just want to shift the text one space to the right without tabbing.
Any suggestions?
Hold down the alt key, left-click and hold the mouse button down on the first line where you wish to insert your space. Then, while still holding down the left mouse button, drag the mouse vertically to extend this edit point to all the lines you want to move. Dragging it horizontally will create a box selection, which you want to avoid, as the selected text will end up being replaced, rather than a space be added.
Also, you cannot select individual, disjoint lines to move. You can only use alt-drag over a contiguous block of lines.
Once you have your multiline edit point created, hit the spacebar once.
Tada.
Here's a blog post by Scott Guthrie with more details and a vidya demo
If you don't want to use the mouse, you can use shift+alt+(up, down, left, or right) to create a box selection, or a multiline edit point.
I'm using the UML sequence diagram in gliffy for Jira and I can't seem to move the dotted line to the middle of the alt box - it stays stuck to the top and I don't see a handle for it. How do I move it to the middle?
It's really fiddly but it possible.
1) Double click the top guard condition [If] to go into text edit mode.
2) Add some carriage returns (new lines) at the end - the idea is to move the cursor down to where you want the line to go
If the line doesn't move when you insert the new lines (it's a bit flaky) then click outside the box (to save) and wait a few seconds for it to catch up.
If it still doesn't move the line, then move the shape a little to get it to redraw.
Finally, delete the shape and start again if it still won't move it.
As I said, it's a bit flaky.
I used Interface Builder to create an NSTextField and set its Line Break to Truncate Head (because if its text is too long to display all at once, I'd rather see the last few words than the first few).
My problem is that the modified Line Break compromises my ability to place my cursor in a specific position when making the NSTextField active (a.k.a. First Responder) by clicking the mouse. In this example, the NSTextField is not active, and I attempt to place my cursor between the "L" and "A" in "lazy".
After clicking, the cursor appears before the word "over".
Clearly, the NSTextField is ignoring the modified Line Break, and positioning the cursor as if it were the default. Can I achieve the effect of Truncate Head but keep the ability to place the cursor in a specific location by clicking?
I had the idea to record the mouseDown location, compare that to attributedStringValue's size, and calculate where the cursor should go, but I quickly got in over my head.
Original question: NSTextField keep scrolling at the end
I have the following silly problem:
I placed a single-line NSTextField on my View. The idea would be that it contains a long URL, but in my case mostly the ending is interesting.
So I would like the content to appear like scrolled to the end (so the beginning is not visible if it is longer than the textfield). The problem is that I do not know how to set this properly. I tried the "Text Direction" option to Right To Left which then displays properly, but as soon the user clicks on the field it jumps back to the beginning, thus confusing the user.
Please let me know what I am missing.
Thanks!
This could be more of a Superuser question, but here goes:
I find myself deleting large amounts of text all the time, I do so by holding Shift-Arrow followed by Delete. However I would love to be able to delete in the way you edit in a video editing application, by adding in- and out-points.
You would press the "IN" keyboard shortcut where you would like the edit to begin and the "OUT" where it should end, followed by delete.
Is this crazy? Is there a way to do this in Textmate?
The cursor doesn't move when you use page-down or page-up, so you could just place the cursor at the beginning of the text, move the pointer to the end of the text, or page-down to where the end of the text is and move the pointer to the end, then hold the shift key down as you click after the last character you wish to delete, and all of the text between the first point and the second will be selected. Then you can hit delete. This will work in either direction (select start then end or select end then start).
