When you have opened a folder in a workspace you can do &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;P&lt;/kbd&gt; (&lt;kbd&gt;Cmd&lt;/kbd&gt;+&lt;kbd&gt;P&lt;/kbd&gt; on Mac) and start typing the filename, or extension to filter the list of filenames

if you have:

 * plugin.ts
 * page.css
 * plugger.ts


You can type `css` and press enter and it will open the `page.css`. If you type `.ts` the list is filtered and contains two items.




Press `Ctl+T` will open a search box. Delete # symbol and enter your file name. 

I believe the action name is &quot;workbench.action.quickOpen&quot;.

It is CMD + P (or CTRL + P) by default. However the keyboard bindings may differ according to your preferences.

To know your bindings go to the &quot;Keyboard Shortcuts&quot; settings and search for &quot;Go to File&quot;

It&#39;s &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;Shift&lt;/kbd&gt;+&lt;kbd&gt;O&lt;/kbd&gt; / &lt;kbd&gt;Cmd&lt;/kbd&gt;+&lt;kbd&gt;Shift&lt;/kbd&gt;+&lt;kbd&gt;O&lt;/kbd&gt; on mac.
You can see it if you close all tabs

I hit some shortcut and I can&#39;t find the setting the turn it off. But opening multiple files doesn&#39;t show different tabs.

VSCode showing only one file in the tab bar (can&#39;t open multiple files)

I saw a lot of questions about methods of using `git blame`, but I don&#39;t really understand them.

I see a &lt;kbd&gt;Blame&lt;/kbd&gt; button on top of files on the GitHub interface. Upon clicking it, it shows some diff with usernames on the left bar. What does that indicate?

Why is `git blame` actually used, apart from GitHub?

I&#39;ve very recently migrated to Python 3.5.
This code was working properly in Python 2.7:

    with open(fname, &#39;rb&#39;) as f:
        lines = [x.strip() for x in f.readlines()]

    for line in lines:
        tmp = line.strip().lower()
        if &#39;some-pattern&#39; in tmp: continue
        # ... code

After upgrading to 3.5, I&#39;m getting the:

&gt; TypeError: a bytes-like object is required, not &#39;str&#39;

The error is on the last line (the pattern search code).

I&#39;ve tried using the `.decode()` function on either side of the statement and also tried:

    if tmp.find(&#39;some-pattern&#39;) != -1: continue

\- to no avail.

I was able to resolve almost all Python&amp;nbsp;2-to-Python&amp;nbsp;3  issues quickly, but this little statement was bugging me.

Pretty simple question but can&#39;t seem to find it anywhere online. I&#39;m trying to make a program that depending on the file type will give me the extension.

I want to convert Base64String extracted from file(ex: &quot;AAAAA....~&quot;) to a javascript file object.

The javascript file object what I mean is like this code: 

HTML:

    &lt;input type=&quot;file&quot; id=&quot;selectFile&quot; &gt; 


JS:

    $(&#39;#selectFile&#39;).on(&#39;change&#39;, function(e) {
      var file = e.target.files[0];
      
      console.log(file)
    }

    

&#39;file&#39; variable is a javascript file object. So I want to convert a base64 string to the javascript file object like that.

I just want to get file object by decoding base64 string (encoded by other app from a file) without html file input form.

Thank you.

How to convert Base64 String to javascript file object like as from file input form?

As a complete beginner to programming, I am trying to understand the basic concepts of opening and closing files. One exercise I am doing is creating a script that allows me to copy the contents from one file to another. 


    in_file = open(from_file)
    indata = in_file.read()
    
    out_file = open(to_file, &#39;w&#39;)
    out_file.write(indata)
    
    out_file.close()
    in_file.close()


I have tried to shorten this code and came up with this:


    indata = open(from_file).read()
    open(to_file, &#39;w&#39;).write(indata)


This works and looks a bit more efficient to me. However, this is also where I get confused. I think I left out the references to the opened files; there was no need for the in_file and out_file variables. However, does this leave me with two files that are open, but have nothing referring to them? How do I close these, or is there no need to?

Any help that sheds some light on this topic is much appreciated.

Is there a need to close files that have no reference to them?

I&#39;m trying to use [GitHub&#39;s code search](https://github.com/search) to search for some lines of code containing characters like `=`, `+`, etc.

I understand from https://help.github.com/articles/searching-code/#considerations-for-code-search that these characters are wildcards and have to be escaped, otherwise they will be ignored.

Here&#39;s an example: [&quot;if \$done is True\$&quot;][1], and another: [&quot;if (done is True)&quot;][2]. 

Both return the same `&quot;your query contains a character that is ignored&quot;` warning on the right side of the search bar. My escaping doesn&#39;t seem to be doing anything and the results I get are with the characters ignored.

How do I escape characters in GitHub code search?

Recently I had an interview, where they asked me a &quot;*searching*&quot; question.  
The question was:

&gt; Assume there is an array of (positive) integers, of which each element is either `+1` or `-1` compared to its adjacent elements.
&gt;
&gt; **Example:**
&gt;
&gt;     array = [4,5,6,5,4,3,2,3,4,5,6,7,8];
&gt;
&gt; Now search for `7` and return its position.

I gave this answer:

&gt; Store the values in a temporary array, sort them, and then apply binary search.
&gt;
&gt; If the element is found, return its position in the temporary array.  
(If the number is occurring twice then return its first occurrence)

But, they didn&#39;t seem to be satisfied with this answer.

What is the right answer?

Efficient way to search an element

There are a couple of things I do not yet understand the VIM way.

One of these is searching in a project like so (using VIM in Atom):

I use CtrlP currently for file names, but what about the contents? 

How can I search with a string, and then look through a list of all occurrences using VIM and/or VIM plugins?

How do I search in all files of my project using VIM?


I usually work on larger projects with many files that would contain the search query. So I would open the files I want to modify and do a find/replace across all currently opened files. Can this be done in vs code?

The feature I&#39;m looking for is implemented in Notepad++, but I&#39;d prefer not to have to switch editors for this task.

VS 2017&#39;s new &quot;Go to All&quot; (Ctrl + T or Ctrl + ,) does not lists items for me.

Searched for a setting for it, no luck. Also no error messages regarding this at all. Any ideas?

Thanks.

Visual Studio Code now [supports JSX on 0.8 version][1], but looks like the only way to activate it is with a `.jsx` file extension. It is not on the list to change the language mode manually, the nearest option is `JavaScriptReact`, but it doesn&#39;t parse the JSX tags.

I&#39;m in a project with a lot of `.js` files with JSX and I can&#39;t change it.

Is there any other way to use JSX syntax without the `.jsx` extension?

Change language to JSX in Visual Studio Code

Let&#39;s say I type in the following code and format it.

    if (condition) { /* Hello! */ }

If this is C# code, it is formatted like this:

    if (condition)
    {
        // Hello!
    }

If it is JavaScript, VSCode formats it like this:

    if (condition) {
        // Hello!
    }
So how can I use the first formatting style (curly braces on new lines) for all languages? I can&#39;t find a setting or something similar. Suggestions?

How do I set up VSCode to put curly braces on a new line?

I&#39;m using the new [Visual Studio Code][1], which is clearly not ready for prime time yet, but I&#39;m hoping to resolve a problem I&#39;m having.

In a SQL file, any time you type &lt;kbd&gt;c&lt;/kbd&gt;&lt;kbd&gt;a&lt;/kbd&gt;&lt;kbd&gt;s&lt;/kbd&gt;&lt;kbd&gt;e&lt;/kbd&gt;, it automatically adds `end`, as if you were building a `case` block. Even if you&#39;re in a comment, or using `Case` as part of a word (for example, `select CaseID from...`).

I&#39;d like to disable all of that nonsense completely, since it doesn&#39;t do a good job of auto completing things for me.

The only configuration options I can find, I&#39;ve already set:

    &quot;editor.autoClosingBrackets&quot;: false,
    &quot;editor.suggestOnTriggerCharacters&quot;: false,

What else can I do to stop this?

It is also true for things like &lt;kbd&gt;b&lt;/kbd&gt;&lt;kbd&gt;e&lt;/kbd&gt;&lt;kbd&gt;g&lt;/kbd&gt;&lt;kbd&gt;i&lt;/kbd&gt;&lt;kbd&gt;n&lt;/kbd&gt; (it adds `end`), and I&#39;m sure lots more.

Prevent autocomplete in Visual Studio Code

Is the `.vscode` folder meant to be committed to source control? 

In a fresh project, the folder is empty, except the `settings.json` file. What kind of things would go into this folder? Is it machine-specific, developer-specific like the `.vs` folder and thus not be committed? Or should all developers share this folder and thus it should be committed?

The comment at the top of the file `.vscode/settings.json` states:

    // Place your settings in this file to overwrite default and user settings.
    {
    }

This seems to imply that the folder should contain project-specific settings and thus be included in source. Also, [this post on UserVoice](https://visualstudio.uservoice.com/forums/293070-visual-studio-code/suggestions/8868625-rename-settings-to-vscode-move-typings-in) seems to imply some typings would go in there, also suggesting that it should be committed. 




Should I commit the .vscode folder to source control?

When I want to change from double quotes to single quotes, I&#39;m used to selecting the double quote, and then type a single quote. I&#39;m intending to use the overwrite feature, but instead, I&#39;m getting the &#39;wrap with quote&#39; feature.

For example:

    &quot;id&quot;

Would result in:

    &#39;&quot;&#39;id&quot;

I always turn this auto surround with wrapping off, but I was unable to find a setting for this in the settings file...

Is there a way to turn this off?

Visual Studio Code: Disable quote wrapping text selection

In **IntelliJ IDEA**, is there an option to find and replace a symbol for whole project with on time operation?

Find and Replace symbol for whole project intellij?

Suppose I have a structured dataframe as follows:

    df = pd.DataFrame({&quot;A&quot;:[&#39;a&#39;,&#39;a&#39;,&#39;a&#39;,&#39;b&#39;,&#39;b&#39;],
                       &quot;B&quot;:[1]*5})
The `A` column has previously been sorted. I wish to find the first row index of where `df[df.A!=&#39;a&#39;]`. The end goal is to use this index to break the data frame into groups based on `A`. 

Now I realise that there is a groupby functionality. However, the dataframe is quite large and this is a simplified toy example. Since `A` has been sorted already, it would be faster if I can just **find the 1st index** of where `df.A!=&#39;a&#39;`. Therefore it is important that whatever method that you use **the scanning stops once the first element is found**.
