Is it possible to easily change fold behaviour in VS Code? What I'm specifically looking for, is a way to fold ALL sections containing "#Region <> #EndRegion" and "Function Get-Example { <> }" with one keybind, without folding any other blocks of code.
Have tried "CTRL+K,CTRL+0", but this also folds/collapses every other kind of blocks - which I don't want. Also tried "CTRL+K,CTRL+n" but not getting the desired result.

When i click "Format Document" button inside of page, it looks like this,
From what I can tell, you are trying to solve the awkward line wrapping and deep nesting problem. When your code gets nested as deep as it is, it hits the column word wrap limit and the limit forces forces the formatter to break items that would normally be on one line into several. There are a couple things you can do:
Best option: Refactor your code and split it into multiple classes/ files. That will make it so that you don't have as deeply nested code and it will make it more readable as well as more maintainable.
Go to the vs code settings and search for Dart: Line Length and edit the value to set when the file starts wrapping content.
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
but works g

I've been using code folding in vim using the kent extensions that allow for folds to be specified in any language using {{{ and }}} markers. For example, OCaml I would say:
(* {{{ comment *)
code
(* }}} *)
and in LaTeX I might say:
% {{{ name
text
% }}}
The vim folding looks for the {{{ }}} pairs as the start/end markers for a fold. I found some examples of specifying custom folding markers as part of creating a brand new language extension in VSCode, but I haven't been able to figure out how to add the {{{ and }}} markers as part of my user settings. I'd prefer to not have to modify existing extensions to use these style markers.
I'm working with a large code base that already makes extensive use of these folding markers, and for the time being I end up being in vim if I want to take advantage of them. I'd really like to be able to move to vscode more, but the lack of this folding mechanism is blocking me.
You might find this comment and this feature request relevant.
Essentially, each language has specific markers supported. However, it sounds like there's a good chance that configurable markers will be implemented sometime in the future.
The Explicit Folding extension appears to be exactly what you're looking for, but it's experimental and has known issues.
When using "change all occurences" in VS Code, it will just search the whole file for matches and change them. Is there a similar feature doing the same thing, but limiting it to function or block scope?
Let's take an example where I would need that: I'm having a React file with several components and want to refactor a class component to a functional component, so I'm changing all occurences of this.props to props. However, I obviously don't want to change all the other class components as well that are supposed to stay class components. :-)
This seems like such a standard use case, but I'm not able to find it anywhere in VS Code. If it's not possible (yet, or for some good reasons) is there another way to achieve what I'm trying to do?
Check out the 'Add Selection To Next Find Match' functionality. It allows you to highlight the first occurrence you'd like to change, then using a keyboard shortcut, highlight the next occurrence and so on until you've selected all the instances you want to change. When all to-be-changed occurrences are selected, you can edit the selected text normally. Just remember to hit the escape key a couple times after editing to return to a single cursor!
Here are the keybindings for the command, it's Cmd+d on Mac:
https://code.visualstudio.com/docs/getstarted/keybindings
I find it very useful when renaming variables, there's also a shortcut to skip occurrences (Cmd+k Cmd+d) in case there is text you don't want to change in between.
I've been trying to make use of a cool feature of YASnippet: write snippets containing embedded Emacs Lisp code. There is a snippet for rst-mode that surrounds the entered text with "=" that is as long as the text such as in
====
Text
====
Based on this snippet, I decided to slightly modify it (with Elisp) so that it comments out these three lines depending on the major mode you are in (I thought that such a snippet would be useful to organize the source code). So I wrote this:
${1:`(insert comment-start)`} ${2:$(make-string (string-width text) ?\-)}
$1 ${2:Text}
$1 ${2:$(make-string (string-width text) ?\-)}
$0
This code works relatively well except for one problem: the indentation of these three lines gets mixed up, depending on the major mode I'm in (e.g., in emacs-lisp-mode, the second and the third lines move more to the right than the first line).
I think the source of the problem might have something to do with what comes after the string ${1: on the first line. If I add a character, I have no problem (i.e., all three lines are correctly aligned at the end of the snippet expansion). If I add a single space after this string, the misalignment problem still continues though.
So my question is: do you know of any way of rewriting this snippet so that this misalignment does not arise? Do you know what's the source of this behaviour?
Cheers,
From Writing snippets:
yas/indent-line
The variable yas/indent-line controls the indenting. It is bound to 'auto by default, which causes your snippet to be indented according to the mode of the buffer it was inserted in.
Another variable yas/also-auto-indent-first-line, when non-nil does exactly that :-).
To use the hard-coded indentation in your snippet template, set this variable to fixed.
To control indentation on a per-snippet basis, see also the directive # expand-env: in Writing Snippets.
For backward compatibility with earlier versions of YASnippet, you can also place a $> in your snippet, an (indent-according-to-mode) will be executed there to indent the line. This only takes effect when yas/indent-line is set to something other than 'auto.
