Column/multi selection mode
显示 更早的评论
Is there a way in the Matlab editor to select vertical selections of text (like Alt-selection in MS word or Notepad++) and to insert text or an incremented numbered list into a vertical selection? (Notepad++ has this by pressing Alt-C, but can only increment)

Dear MathWorks, please implement this functionality. A "Column Mode" in Editor would be fantastic. Also, a "Column Mode" where you can increment numbers would save time as well. In 2017, we still have to open UltraEdit and Excel to do this and paste results in MATLAB.

Hi all -- column selection mode, or block edit mode, was added to the Live Editor in R2018a, and to the regular MATLAB Editor in R2021b. You can select and edit a rectangular area of code by pressing the Alt key while making a selection with the mouse (or the Option key on macOS). This is mentioned briefly in the release notes for those releases and also in the documentation page for editing and formatting code. Please go ahead and try it out!!

This feature would be very useful - please keep us up to date about the plans when this feature will be available in regular editor.

selecting a rectangular area of code is a great first step, but being able to select different lengths of text in each row would be better! (VS Code is good at this)

No, but I agree it would be useful!
Every other day I copy blocks of code to Notepad++ to use "vertical selection" and regular expressions.

I'll second this, it's hard to overestimate how much time this feature would save me on a daily basis!

Mathworks really needs this column edit feature in their editor. There's no reason not to have it and I end up having to temporarily open another editor just to edit something and going back to matlab editor afterwards. Why is this not already available????
also was looking for multi line selection, have made this function to open file in notepad++.
Can be used to fast open in any editor, good to assign it to some keyboard shortcut
function edit_in_npp()
% the function will open active in editor file in npp in the corresponding line
% before use check that npp is in your system path or set path to npp_path
% variable below.
% to set path from cmd use setenv('PATH', [getenv('PATH') ';C:\Program Files (x86)\Notepad++']);
npp_path='notepad++.exe'; % or set npp_path=C:\Program Files (x86)\Notepad++\notepad++.exe
doc=matlab.desktop.editor.getActive;
system(sprintf('"%s" "%s" -n%d',npp_path,doc.Filename,doc.Selection(1)));

Very good! Suggest adding an ampersand to the sprintf('... &'). I needed to use the full path to notepad++

I have to use notepad ++ to make easy tasks which the regular editor should be capable of. The is no need to do that in the live editor. This is standard feature for decades.

Hi Maxim, column selection mode is available in the regular MATLAB Editor as of R2021b.
Thanks,

I see no evidence that Mathworks will be making any feature changes to the regular editor, other than in the sense of continuing to work on the code analyzer and autofixes. Otherwise all of the editor development appears to be going into the live editor. Thus I do not expect the column cut or paste to ever be put into the regular editor. I would instead suspect that the live editor is intended to replace the regular editor in time.

Two years later, now I concur with you...I am switching to VScode to edit matlab now. Even though I lost cell mode, overall I am pretty happy.

The features of the Live Editor such as column/block selection (as well as refactoring, duplicate line, and other desirable text editing features) will be available in the regular MATLAB Editor imminently.

The R2021b pre-release has this feature in the regular editor.

In the R2021b pre-release, could you please explain how to select text columnwise on an OSX system? Which key combination should I use?

Hold down alt and left click and drag.
(Or... left click and drag letting it be messy and selecting everything not just columns; and then hold down alt and move the mouse (movement is required!!), and it will switch to column selection. But I do not recommend this approach.)

It works. Thank you.

On Linux, the Alt shortcut clashes with the Plasma Window Manager shortcut. Change is not feasible on modern notebooks since there is no Meta key on keyboards. Please make it possible to alter the column selection shortcut from Alt to something else.

Hi zmi zmi,
Unfortunately there's no way to change the shortcut for column selection right now, we're still looking into this. In the meantime if you need to disable column selection altogether to avoid conflicts, the command to run is:
>> s=settings;
>> s.matlab.editor.EnableColumnSelection.PersonalValue=0;
