In NetLogo is there a way to treat a text string as a command and execute it?
In the simplest case - is there way to simply generate a text string like "forward " concatenated with a number I don't know till runtime, so i end up with a text variable equal to "forward 8", say, and then execute that command?
My immediate need is probably what LOGO did, namely, have the user click buttons to move a turtle around with the pen down to draw some shape, say a square, saving those commands as they are written to an output window, saving the full text of the output window to some named text like "draw-square", and then have the user able to type "draw-square" in the command center and have the turtle execute those steps and draw a new square.
I could work around this I suppose by exporting the output to a myfile.nls text file, then restarting NetLogo to bring in the new command file using the __includes [ "myfile.nls"] step , but I'd rather not ask them to do that if I can avoid it and in any case that wouldn't work over the web.
Jasper answered the question in the comment above -- "run" and "runresult" do what I wanted.

I'm using visual studio code and run into a weird problem. I'm not sure how I got here - I could have accidently pressed a shortcut unknowingly.
I'm trying to select a phrase, link or anything that crosses multiple lines (whether the lines are true lines or due to word wrap). When I select multiple lines, it doesn't automatically select the text at the start and end between the two points. Rather, it just selects the length of text for that line and repeats it in the subsequent lines. See the image below to understand.
Image of issue
As you can see, I am trying to select the words from "the" to the end of "sub". Instead of selecting all the words between the two, it selects the text "the instru" and selects every line with the same amount of characters/length.
In order to show what I am expecting, I have pasted the text into Notepad and done the same thing.
What I am expecting
As you can see, all the words between "the" and "sub" are selected.
If anyone has any idea about how to fix this, I would be greatly appreciative.
Below is a copy of the text if the images don't display.
Follow the instructions below for a click guide to retire and/or add 'School'.
Best practice if there is a change in 'School' structure would be to 'retire' any existing school setup that is no longer required and add the new sub school information. The reason why we don't just edit existing school names (typically) is due to leaving historical data intact.
Try using ctrl+shift+P and typing "Toggle Column Selection Mode"
Having trouble finding a way to do this, maybe it is not even possible?
In my case, for testing flow of if-statements/user-interaction, am temporarily adding 40 lines of console.log('trigger-fired-1'); throughout our code.
However, to tell them apart would like each to end with a different number, so in this case, numbers one to forty like so:
In the screen recorded gif, to replicate what I am going for, all I did was copy/paste the numbers one to nine. What I really would like is a shortcut key to generate those numbers at the end for me to eliminate that step of typing out each unique number.
Am primarily coding in Visual Studio Code or Sublime Text, and in some cases shortcuts are similar, or at least have same support but for different shortcut keys.
There are a few extensions that allow you to do this:
Text Pastry
Increment Selection
NumberMonger
For Sublime Text, the solution to this problem is the internal Arithmetic command. Something similar may or may not be available in VS Code (possibly with an extension of some sort) but I'm not familiar enough with it to say for sure.
This command allows you to provide an expression of some sort to apply to all of the cursor locations and/or selected text.
By way of demonstration, here's the example you outlined above:
The expression you provide is evaluated once for every selection/caret in the buffer at the time, and the result of the expression is inserted into the buffer (or in the case of selected text, it replaces the selection). Note also that when you invoke this command from the input panel (as in the screen recording) the panel shows you a preview of what the expression output is going to be.
The special variable i references the selection number; selections are numbered starting at 0, so the expression i + 1 has the effect of inserting the selection numbers starting at 1 instead of 0.
The special variable x refers to the text in a particular selection instead. That allows you to select some text and then transform it based on your expression. An example would be to use x * 2 immediately after the above example (make sure all of the selections are still present and wrapping the numbers) to double everything.
You can use both variables at once if you like, as well as anything in the Python math library, for example math.sqrt(i) if you want some really esoteric logs.
The example above shows the command being selected from the command palette interactively, where the expression automatically defaults to the one that you want for your example (i + 1).
If you want to have this as a key binding, you can bind a key to the arithmetic command and provide the expression directly. For example:
{
"keys": ["super+a"],
"command": "arithmetic",
"args": {
"expr": "i+1"
},
},
Try this one ...
its not like sublime

I'm trying to use the multi cursor functionality of vscode on a large(ish) file.
the file is too large to select every line individually with ctrl-alt-up or down. In sublime-text I would select everything and push ctrl-shift-l. Is there a similar thing in vscode. I've tried using a regex search for ^, but that gives me an error stating "Expression matches everything".
The command Selection / Add Cursors to Line Ends altshifti will put a cursor on every line in the current selection. (For mac use optshifti)
Tip: You can pull up the keyboard shortcut reference sheet with ctrlk,ctrls (as in, those two keyboard combos in sequence).
(For mac use cmdk,cmds)
Hold Alt+Shift and select the block. Then press End or Right button.
You get selected individual lines.
I use version VSCode 1.5.3 in Windows.
Hold Alt+Shift+i
Hold Home (fn+-> Mac) for right-most or End for left most(fn+<- Mac)
This feature is actually called split selection into lines in many editors.
Sublime Text uses the default keybinding, CTRLSHIFT L
VSCode uses ALTSHIFTI
For Atom you actually need to edit your keymap to something like this
'.platform-win32 .editor, .platform-linux .editor':
'ctrl-shift-L': 'editor:split-selections-into-lines'
Real Lines vs Display Lines
First we have to understand the difference between Real Lines and Display Lines to completely understand the answer of the question.
When Word Wrap is enabled, each line of text that exceeds the width of the window will display as wrapped. As a result, a single line in the file may be represented by multiple lines on the display.
The easiest way to tell the difference between Real Lines and Display Lines is by looking at the line number in the left margin of the text editor. Lines that begin with a number correspond to the real lines, which may span one or more display lines. Each time a line is wrapped to fit inside the window, it begins without a line number.
Cursor At the Beginning of each Display Lines:
Cursor At the Beginning of each Real Lines:
Answer to the Question
Now that we know the difference between Display Lines and Real Lines, we can now properly answer the actual question.
Hold AltShift and select the text block.
Press Home to put cursor on the beginning of every Display Line.
Press End to put cursor on the end of every Display Line.
Press HomeHome (Home twice) to put cursor on the beginning of every Real Line.
Press EndEnd (End twice) to put cursor on the end of every Real Line.
Please understand that AltShiftI put cursor on the end of every Real Line.
Install the extension Sublime Commands.
[Sublime Commands] Adds commands from Sublime Text to VS Code: Transpose, Expand Selection to Line, Split into Lines, Join Lines.
(Don't forget to add the keybinding(s) from the extensions details page to your keybindings.json)
Doesn't VS Code already have a "split into lines" command?
Yes, yes it does. However it differs from the one in Sublime.
In VS Code, when you split into lines your selection gets deselected and a cursor appears at the end of each line that was selected (except for the last line where the cursor appears at the end of the selection).
In Sublime, when you split into lines a cursor appears at the end of each line (with the same exception as in VS Code) and the selection is divided on each line and "given" to the same line.
I have the same problem, i'm used to Alt + drag to do 'box selections' in visual studio but it does'n work in code.
It seems to be impossible for now to do it differently than by selecting every single line.
However plugins should be supported soon so we will likely see a plugin for this if not implemented directly by microsoft.
From visual studio uservoice forums:
We plan to offer plugin support for Visual Studio Code. Thank you for your interests and look for more details in our blog in the coming weeks. http://blogs.msdn.com/b/vscode.
For the preview we are looking for exactly this type of feedback. Keep it coming.

I'm trying to move to a specific column number in a Sublime Text macro command, so that I can delete everything after that point, but I can't get the move command to work.
I've compared the old and new versions of the unofficial documentation, and it looks like the move command used to have an "amount" parameter, but it hasn't been working for me. So the reason I'm writing is because I feel like there's something the docs are leaving out, but I don't know what it is, or how to even debug it in Sublime Text.
Here's an example of what I'm trying to do:
/*//////////////////////////////////////////////////////////
// Comment Block ///////////////////////////////////////////////
//////////////////////////////////////////////////////////*/
When the caret is at the end of the phrase "Comment Block", I need to run a command that advances the caret to a specific column number. After that, I can expand the selection to the end of the line and delete, trimming the line to be equal with its counterparts.
I think it should be pretty simple what I want to do, basically I have one edit box that displays a value in percentages and another that I want to update to display raw values. I've tried using the following code under the edit1 (percent) callback:
currentKey = str2num(get(gcf,'CurrentKey'));
percent = str2num(get(handles.edit1,'String'));
if ~isnan(currentKey) && ~isnan(percent) && 0<=percent && percent<=100
set(handles.edit2,'String',num2str(2*percent))
end
But it will only update the second edit box if I first click outside of the first one. Anyone have an idea of what I should be doing?
Thanks!
I think this link should help you:
How can I make the text that I enter into an edit text box update dynamically?
Solution:
This enhancement has been incorporated in Release 2011a (R2011a). For previous product releases, read below for any possible workarounds:
This is expected behavior of the Edit Box UICONTROL in MATLAB.
You can try using the 'keypressfcn' to grab the keyboard input. The attached two files demonstrate the ability of real-time text update. As you enter text into the upper edit box, the text will be copied to the edit box beneath it as you enter.
Please download the following two files:
test_keypressfcn.m
test_keypressfcn.fig
Execute the program.
A GUI will appear. Enter text in the upper edit box displayed in the GUI.
Observe the text in the lower editbox is updated dynamically or in real-time as you enter test in the upper edit box.
Please note that this will work only for text that is continuously entered in the editbox. If you type in between words already entered in the editbox the gui will not perform as expected. You will need to implement logic similar to the one in this example to get the behavior that you desire.
