Neovim remap for vscode for commenting doesn't work - visual-studio-code

This is my current code
map z, <Cmd>call VSCodeNotifyRange('editor.action.commentLine', getline('.'), getline('.') + v:count1, 1)<CR>
Usage of VSCodeNotifyRange used as explained in the Neovim extension's readme:
What I'm trying to do: I pass a number to the remap, for example 5z,
The current line and four next lines are selected in vscode, and then commented out
What's happening: nothing gets commented out, and I get jumped to the line I specified the number to
So when I use 5z, I end up on line 5 (absolute). When I use 10z, I end up on line 10, and so on
I imagine this is a syntax issue, any help would be appreciated

How do I get a cursor on every line in vscode

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.

comment out an interval in matlab through command line

I have a very long script in MATLAB (1500 lines) and want to test two different settings. To do so, I need to comment out some codes in a specific interval (e.g. form line 234 to line 255).
Is there a function in MATLAB that takes the intervals and comments/uncomments them automatically?
You can just highlight your code and click on the comment button. Highlight and click on uncomment to remove comment.In windows you may also use shortcut keys cntrl+r and cntrl+t. But yeah, the if else is a better idea but takes more time in the beginning to code in the if else.
I would agree with others that putting your code into a block surrounded by if-else would probably be a better solution than what you originally asked for.
But if you want to do it, you can use the following function:
function commentout(fromline, toline)
currentDoc = matlab.desktop.editor.getActive;
currentDoc.insertTextAtPositionInLine(sprintf('%%{\n'), fromline, 0)
currentDoc.insertTextAtPositionInLine(sprintf('%%}\n'), toline+1, 0)
This will work in most recent versions of MATLAB.
To uncomment, I think you'll need to do something a bit more complex, like getting the entire text from the active document, removing the specified comment lines, then setting the entire text back again (get, modify and set the Text property of the document).

Sublime Text Macro Command Move to Specific Column Number

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.

how to freely format comments in cc-mode

I'm quite new to cc-mode and I'd like to configure it to allow me to freely format and use tabs in multiline comments. This is important to me because I want to use cog.py in my source file and need to be able to format the python source in the comment correctly. I'd be ok with comments not beeing autoindented at all, however I'd like to keep auto indenting the rest of the source code.
Example:
...
/*
[[[cog
import cog
for x in ['a','b','c']:
>cog.outl(x)
]]]
*/
...
In the line marked with > I'd like to press TAB to indent the line. cc-mode simply does nothing at all if i do so. I could use spaces there (which is inconvenient) but every (semi-)automatic re-indentation of this block would cause the spaces to vanish and therefore the python code to be incorrectly indented (which is what happens if i happen to press tab somewhere on this line after indenting it with spaces).
I tried to start emacs without my .init to be sure this is default behavior and not modified by my configuration so far. I've done google searches and read the documentation of the cc-mode variables / functions I stumbled upon (cc-mode online docs) while searching for a solution (i.e. c-indent-comments-syntactically-p, c-indent-command, c-tab-always-indent,...) but none of these seemed to solve my question.
EDIT1:
Thanks to abo-abo's idea of a "multi-major-mode" setup i've stumbled upon mmm-mode and have set up automatic switching to python mode for a cog section, which fixes most of my problems.
The only remaining problem is reindenting the whole file or a region containing a cog section. Can I somehow tell cc-mode to not change anything in comments while reindenting the file? mmm-mode + that would be a perfect solution for me.
You can use M-i to force a tab indent on the lines that you want, so you can use it to indent your comments.
You can also change your comments to use // instead. Just select your python code snippet, and do M-x comment-region:
// def foo(x):
// print 'hi'
Then the autoindent won't mess up your indentation.

Unexpected 'INDENT' in CoffeeScript Example Code

As I was playing around for the first time with CoffeeScript, I ran in to a problem. In order to debug my problem, I tried replacing my whole file with one of the example bits of code from the coffee script site:
kids =
brother:
name: "Max"
age: 11
sister:
name: "Ida"
age: 9
However, when I try to compile that code, I get:
Error: In coffee/main.coffee, Parse error on line 3: Unexpected 'INDENT'
at Object.parseError (/usr/lib/coffeescript/parser.js:501:11)
at Object.parse (/usr/lib/coffeescript/parser.js:573:32)
at Object.compile (/usr/lib/coffeescript/coffee-script.js:23:22)
at /usr/lib/coffeescript/command.js:99:27
at /usr/lib/coffeescript/command.js:72:28
at fs:84:13
at node.js:773:9
In coffee/main.coffee, Parse error on line 3: Unexpected 'INDENT'
Since this is code from the CoffeeScript site, I assume the code itself isn't the problem. However, the compiler also seems to be working properly; if I compile:
a = 2
it generates a file with:
(function(){
var a;
a = 2;
})();
as expected. So in other words, the code is good, the compiler is good, and yet somehow I'm getting this Unexpected 'IDENT' error ... can anyone help me understand what is going on?
I am pretty sure this is a tabs-vs-spaces issue. Tell your editor not to convert spaces to tabs if it does that. Also, go through your code with the cursor and make sure it doesn't jump over blank areas.
The issue is that while normal editors see a tab as equivalent to two or four spaces, coffeescript sees it as one space, so the indentation gets messed up.
If this all doesn't help, make sure you have a recent coffeescript version, e.g. 1.1.0 or newer.
If you are using a JetBrains IDE (IntelliJ, PHPStorm, etc) the change of setting that worked for me is:
File > Settings > Project Settings > Code Style > CoffeeScript > Tabs
and Indents
Tick "Use tab character" & "Smart tabs"
Code is fine. Make sure you haven't messed up the whitespace (strange control chars showing as blanks, tabs or similar).
If you have the same problem, but your indentation is okay,
then you must be suffering from bug 2868.
Basically, the error is misleading. Check for indentation
errors in the required files.
When in Atom you can automatically convert tabs to spaces:
Packages > Whitespace > Convert Tabs to Spaces
You can resolve this two ways
1. IF using webstorm File->Default Settings as said above
2. Other workaround, is to use a different editor like Sublime, there u can press enter on earlier line and it will auto tab it for you with spaces
