Can you fold a highlighted selection of code?

6 views (last 30 days)
I have enabled cell folding with the double percent signs, %%.
I can click each individual +/- on the left hand side of my script window to expand or fold cells now. I can also right click the window and click 'Fold' or 'Fold all'
I want to fold all cells in a section of a few thousand lines of code in the middle and leave open the rest. There are many cells in this section making the manual process annoying. I was hoping I could highlight a large amount of code with the cursor, and fold any cells in it.
If I try to highlight that large section and click Fold , it only folds one (The last one)
If I highlight the section and click Fold All, everything in the file folds, including things I haven't highlighted.
Is there a way to only fold the cells I have highlighted?

I agree that this is very much needed. I'd also like to be able to fold all the functions in a methods block of a classdef file by clicking on the block in some way. Currently, when you fold a methods block, you see this,
classdef myclass
methods ... %folded
In addition to that, I'd also like to have a button that folds as follows, where I can see a synopsis of what functions are present in the methods block, and their signatures:
classdef myclass
function obj=F1(arg1,arg2) ...
function obj=F2(arg1,arg2) ...
function obj=F3(arg1,arg2) ...
function obj=F4(arg1,arg2) ...

I think the bigger question is why do you have more than 1000 lines in a file?
Consider breaking it out into smaller manageable functions (which could be folded as a whole function) and which can be in a separate file once they're working..

I frequently inherit poorly formatted code and what I'm asking about would help manage it a lot.
I just want to know if there is a way to fold all cells in a cursor highlighted section of code. It seems like a potentially basic function but it may not be possible.

"why do you have more than 1000 lines in a file" [...] "smaller manageable functions" &nbsp I'm not convinced that's always true. I have huge classdef-files and huge files with unit tests. I use folding systematically and I would benefit from better control over the folding. Now it requires far too many mouse-clicks.
Available tools matters. Search and Search&Replace for one works better with one huge file.
My code evolves through experiments and refactoring and during that process huge files present advantages.
