control+/ does not work to comment multi line in sublime 3 - sublimetext3

I can't comment out multi line in sublime 3. Looked at this Keyboard shortcut to comment lines in Sublime Text 3 already but it is not fixing it
Sublime version is 3.2.1 build 3207 . on windows 10.
Please help me out if have any tips.

The keyboard binding for commenting is indeed Ctrl+/ (Cmd+/ on MacOS) so in the general case what you're trying should work just fine.
That said, the keys in question are bound to the toggle_comment command and that command requires language specific metadata to know what comments are supposed to look like. For example comments look and work differently in HTML than they do in C or JavaScript. Some file types (such as plain text files) aren't code and thus don't have a concept of comments at all.
If the metadata file for a file type is missing, then the toggle_comment command won't do anything because comments are assumed to not be valid, which seems to be what's happening to here.
The first thing to check would be to examine the bottom right of the window to see if Sublime agrees with you about what the file type is supposed to be. For example, newly created tabs are Plain Text files until you save the file for the first time, and comments are not allowed in Plain Text files.
If the file type doesn't say what you think it should, you can click it to open a menu and select the appropriate type for that file.
If the type of the file looks to be correct and the command still doesn't work, then the metadata file needed is not being provided in the package that is adding support for that language. In that case you should raise an issue with whoever is responsible for the package in question and get them to add the appropriate file.
Based on the comments on your question, you think you're editing JavaScript files but Sublime thinks you're editing an ActionScript file instead. The JavaScript package includes the appropriate file, but the ActionScript package does not.
So in your particular case, your best bet is to switch the file type to JavaScript and your problem should go away. If you actually want to be editing ActionScript instead, then you need to create an issue on the Default package tracker and ask for this to be added.

How do you make a specific folder that has subfolders to be uneditable in Sublime Text

How do you make a specific folder that has subfolders to be uneditable in Sublime text? ? I know it's possible but how ? Like i have some old projects that I want to use as a reference to study my old code, but i"m worried that I mistakenly edited some parts of that specific module / file, when I'm mindlessly touring around my code.. How do I do it ? like making a specific folder to be uneditable in sublime text that only modifying it can change it . I mean I tried installing this one package : https://packagecontrol.io/packages/Toggle%20Read-Only
But it still gives me a prompt whenever I want to changed something from a file
Your best bet is to make sure that your source code is covered by some sort of Source Control, such as git or Subversion; this is just always a good idea in general and unrelated to your particular question. Having your code under source control means that when you edit a file (accidentally or on purpose) you can see exactly what you edited or throw those edits away and go back to what you had if you want to. If you also push your code to an external server, such as GitHUb (if you use git) then you also have a cheap and easy off-site backup of your code as well.
That said, if you want to make files uneditable, that's more the job of your file system than the tools that you're using to edit the files (in this case Sublime Text).
All file systems and operating systems should have the concept of a read-only file, which sounds like what you want. A file being marked as read-only stops you from accidentally modifying it; depending on the software that you use, edits are either impossible or will need to be confirmed.
In your case, you can do this in a couple of different ways. If you only want to protect a couple of files, then you would do a Right click and choose Properties; in the bottom of the General tab there is a check box you can check to make that file read-only:
If you have many files, you can do the same thing by editing the properties of the folder that contains the code instead:
When you do this to a folder, the property set works a little differently; since you're modifying the folder as a whole, you need to click the box twice to change it from a square (shown above) to a check mark. When you apply the change, you will be asked if you only want to make files inside of that directory read-only, or all files in that folder as well as all folders under it; choose as appropriate.
Sublime will let you open read-only files and will also let you modify their contents, but when you try to save you will get a warning dialog telling you that the file is write-protected; you need to confirm if you want to actually save changes or not; (other software may not prompt with such a dialog and may just fail):
If you choose to save, you will remove the read-only attribute and make the file normal again.
If you want to make a file completely un-editable so that you can't even accidentally change the file, you can achieve that with a simple plugin in combination with making the file read-only (see this video if you're not sure how to apply a plugin):
import sublime
import sublime_plugin
import os
class ReadOnlyListener(sublime_plugin.EventListener):
def on_load(self, view):
if (os.path.exists(view.file_name())
and not os.access(view.file_name(), os.W_OK)):
view.set_read_only(True)
EDIT: The internal View Package Files command will open package resources from sublime-package files transparently and give them a filename that represents where they would exist on disk if they were not in the package file.
The plugin from the original answer would stop you from being able to use this command by noting that the file is not writable (because it does not exist on disk) and make the view read-only, which stops the file content from being displayed because the view can't be modified.
This is rectified in the edit above by only taking action if the file actually exists on disk (the View Package File command already makes files it loads in this manner read-only if they do not exist on disk).
This makes an event listener that checks every time you open a file to see if the file is writable, and if it's not it makes the view read-only. This distinction is Sublime specific; regardless of the underlying state of the file, you just can't make any changes to such a file at all. That doesn't stop you from saving the file even if you haven't made any changes, which would have the same effect as the above.

Unwanted text appears every time I close a bracket in VIM using VimTex

I am typesetting a latex file in VIM using the Vimtex plugin.
Every time I close a bracket, this text shows up automatically in the <++>.
For example:
\section{This is one}<++>
\section{The variable $V_L$<++> explains things}<++>
\begin{equation}
<+content+>
\label{<+label+>}
\end{equation}<++>
LaTeX compiles my text with those printed out in the pdf so I have to manually remove the every time. This behavior goes from $$ to {} to others also and even inside certain areas when using autocompletion features wit F5.
I did look add this question but it did not provide much help as to how to solve my issue.
How can I prevent the from being added to my tex files?
If they are a feature meant for something I do not understand, how do I prevent them from compiling in my pdf's?
This part of the documentation on the vim-latex (not Vimtex) repo on github
explains how the macro system works, how it's useful and solely meant for editing
NOTE: Place Holders
-------------
Almost all macros provided in Latex-Suite implement Stephen Riem's
bracketing system and Gergely Kontra's JumpFunc() for handling
place-holders. This consists of using "place-holders" to mark off
locations where the next relevant editing has to be done. As an example,
when you type EFI in |insert-mode|, you will get the following: >
\begin{figure}[<+htpb+>]
\centering
\includegraphics{<+file+>}
\caption{<+caption text+>}
\label{fig:<+label+>}
\end{figure}<++>
The text <+htpb+> will be selected and you will be left in |select-mode|
so that you can continue typing straight away. After having typed in the
placement specifier, you can press <Ctrl-J> (while still in insert-mode).
This will take you directly to the next "place-holder". i.e, <+file+> will
be visually selected with Vim in select mode again for typing in the file
aaaa. This saves on a lot of key presses.
Note: Upon testing I realized that the placeholder only appears when the bracketing is empty.

Can sublime 3.0 convert display from plain text to source color scheme automatically?

I'm little new to Sublime, wanted to know if there is a way to change display in sublime-3.0 from plain text to source colors automatically (i.e. Sublime should keep source colring from where code was copied and pasted like- HTML or XML or Java code) without I changing it manually.
Thanks in Advance!
Sublime Text already does this for some languages, like XML.
It works when you have a blank document that is set to Plain Text format (i.e. you open a new tab), and paste something in whose first line can be identified to be a specific language, using regular expressions.
For XML, it looks for an XML prolog or an XML element with a namespace. Regex
For HTML, it looks for a HTML doctype.
It currently doesn't support Java - I guess it's not easy to come up with a regex that would match only the first line of a Java file and not a C# file, for example. If you do have some ideas, you can use https://packagecontrol.io/packages/PackageResourceViewer to edit the relevant .sublime-syntax (YAML) file and add a first_line_match in.
You may also find the following packages helpful:
https://packagecontrol.io/packages/AutoSetSyntax
https://packagecontrol.io/packages/ApplySyntax
Extra note: these "first line matches" also apply when opening files that aren't automatically matched to a syntax by the file's name/extension.
There might be a better way, but I've done it with the Package control ctrl+shift+p (Win, Linux) or cmd+shift+p (OS X). Search for Package Control: install Package, press Enter and then search whatever package you need.
After installing the SCSS package, I'd get the HTML colouring as well.

Tabcompletion and docview while editing rc.lua

I saw that there is a lua plugin for eclipse and there is a docpage on the awesome main page api_doc and all the .lua files in /usr/share/awesome/lib.
So I thought it must be possible to create a Library or Execution Environment so that one has tabcompletion and docview.
So I tried making my own Execution Environment:
wrote the standard .rockspec file
downloaded the documentation made an ofline version of it and put it in docs/ folder
ziped the files and folders in /usr/share/awesome/lib
ziped all up
tried it out ... and it failed.
When I try to view a documentaion for a .lua file I get "Note: This element has no attached documentation."
Questions: Am I totaly wrong in my doing (because I have the feeling I am)? Is there any way to edit the rc.lua with tabcompletion and docview?
Koneki will probably take a while to setup, but it's definitly worth it. Going for the".doclua"(by using version 1.2) would certainly make it, but I doubt that using a script to generate the information you need, would work out on the long run.
Most likely, you'll probably pass a bit of time to define what kind of object you're dealing with every time you come across one. The right to do, would be to actually take the time to see if the object/module/inner type inherit from an another object, so can actually have more completion feature as you keep using autocomplete to go from one object to another by pressing "dot"+ctrl_space.
In an ideal world, one person could probably make it right and share to other, so they can enjoy a full featured autocomplete editor.
Found solution for eclipse.
First off the idea of setting up an Execution environment was the wrong one.
So the whole thing about downloading the doc although.
For more information on that visit eclipse Wiki for LUA Development Tool.
The right thing to do is to add a source folder which contains the /usr/share/awesome/lib directory.
The bad news is that my comment from above was totally right, which means one has to configure each .lib file in /usr/share/awesome/lib to meet the requirements of the Documentation Language described here.
Than editing the rc.lua (which one can add to the project in eclipse) works with tabcompletion and doc view.
Since the Documentation Language used in the lib files is similar to the one used by "LUA Development Tool" one has not to change many things. Maybe there are even scripts for that.

Opening the header file to a C/C++ source file with vim from multiple directories and multiple extension

First off, I was about to write a long list of if/else statements in vim and realized that 1) there was a better way to do what I was trying to do and 2) SO would be ripe with help on the subject. So! I have a variety of files spread about like
foo/src/file01.C
foo/src/file02.cc
foo/src/file03.c
foo/include/file01.hh
foo/include/file02.h
foo/include/file03.h
If you notice that the C/H, cc/hh, c/h extension may or may not match then you are keen and I'd like you to please help. I've look at things like the following vim scripts from the Vim wiki for "Easily switch between source and header file" and although I only dumped a few hours into a.vim without success, it doesn't seem that the others would work via the docs on that page. So can anyone help out on how to make this work?
A good lead I had was a quick How to Easily Switch between Header and Source topic, but still couldn't make it work.
I guess what I really want is how to avoid the multiple if statements and use real matching to do what I want. I want to look into another directory and if look for a header file of the same name with any familiar extension if it was a source C/C++ file, or look for a source file of any regular extension if it was a header file. Thanks for your help!
UPDATE: I specifically want to open the file in a new tab. I live on vim tabs!
I recommend using the FSwitch plugin. https://github.com/derekwyatt/vim-fswitch
This does exactly what you need out of the box. It is better than a.vim in more than one way, being a rewrite of the idea behind a.vim.
The link you posted presents it as a solution, too.
I have just installed it to my vim configuration and it does its job well.
Enjoy.
Just to make sure I was using the most current version, I downloaded the latest a.vim script (2.18) and copied it into my ~/.vim/plugin directory.
You can define certain variables in your ~/.vimrc file to get a.vim to recognize alternate file extensions.
To get the files in your example to match their alternates I added the following to my ~/.vimrc:
let g:alternateExtensions_C = "H,hh"
let g:alternateExtensions_hh = "C"
These are global variables that allow you to override what's already defined. You'll have to define
both relationships (they don't work both ways).
You can see what the current mappings are by typing:
:echo g:alternateExtensionsDict
If you need to define other mappings, follow the same pattern. What comes after the underscore is the file extension you're editing. What's in the double quotes is a comma-separated list of alternate extensions.
let g:alternateExtensions_<ext> = "<list,of,alt,ext>"
If you have a different directory structure, you can define what paths to search by overriding the g:alternateSearchPath variable. ../src and ../include are already included by default.
:echo g:alternateSearchPath
To open the alternate file in a new tab:
:AT
By the way, the a.vim script is pretty well documented. You might want to open it up and take a look. I found a setting or two that I didn't know about and I've been using it for years ;o)
I hope that helps.
IMO your best option is to adopt existing scripts to use :tabf instead of :e or whatever the scripts use right now to open the counterpart file. You can also try to make the change configurable and submit it to the script author. (I'm pretty sure many would find the enhancement useful.)
That reminded me of a trick I used very long time ago. Instead of guessing where the corresponding source/header files are, I have used at the top of file special comment containing relative path to the counterpart file. Switching was as simple as finding the special comment, extracting file name and opening it. Problem was similar to yours in that file extensions were not predictable. My rational solution was to stop guessing and denote counterparts explicitly in the source code. (This days I would have probably tried to put the relationship table into an external file with a standard name and look it up in VIM using the upward search.)
Two helpful things
:he 'path'
:he tabfind
So you would do
:set path=../,/usr/include/,/home/buildagent/SDKROOT/mysdk/inc
:tabfind error_codes.h
to open error_codes.h from somewhere exotic without having to specify it. Note how vim globbing is very very flexible, so you might not need mucht
:argadd ./**/*.[h,H] | tab sall
will open all header files under the current directory, regardless of how many levels deep. Be careful running this command on a large tree or with symlinks outside the tree
