I'm building a VS Code extension which includes changing the name/title of untitled-1 tab (unsaved file).
I tried running the below code in debugger console of extension but it didn't reflect in the editor:
vscode.workspace.textDocuments[0].fileName="myFile"
Is it not possible or am I missing something?
It is still (Q1 2020) not possible, but the next VSCode 1.42 will name its Untitled editors differently.
Untitled editors in VS Code are text buffers that have not yet been saved to disk.
You can leave them open for as long as you like and all text content is stored and restored between restarts.
Untitled editors were given generic names such as Untitled-1 and counting upwards.
In this release, untitled editors will use the content of the first line of the document for the editor title, and include the generic name as part of the description:
Note: If the first line is empty or does not contain any words, the title will fall back to Untitled_* as before.
So while you cannot set the title yourself (still readonly fileName), technically... changing the first line of that file would be enough to change the title of said "Untitled" editor.
With VSCode 1.43 (Q1 2020), a new setting workbench.editor.untitled.labelFormat allows to control whether untitled editors should use the contents as title or not.
Possible values are content or name.
Configure 'workbench.editor.untitled.labelFormat': 'name' to get the previous behavior back where untitled editors would have a short title, such as Untitled-1.
It's not possible - if you check out the source code for the API definition in vscode.d.ts, you'll see that fileName is declared as readonly:
export interface TextDocument {
// ...
readonly fileName: string;
// ...
}
Unfortunately, it seems that the readonly attribute isn't reflected in the API docs on the website.
This mainly happens if we create a new file in the OPEN EDITORS section, thus they appear as unsaved. To prevent this, create a folder for storing your files, and then in that folder, create your new file then it will show options to name it, also you can add a file type extension like .cpp.
TIP: vsc-rename-files extension to rename your files.

VS Code is aware of many file types, but I cannot find any information on where to see all file types it currently understands.
I want to see which file type is associated with which language.
If I view the file associations it's totally blank:
I want to add a new association. I want to associate *.inc as a restructured text file. But figuring this out is a guess right now, what is the "code" for the restructured text language?
Is it rst:
Or is it "restructured text"? Or another value. My VS Code currently associates *.rst files with restructured text, but I cannot see that configuration anywhere.
The easiest way I've found for a global association is simply to Ctrl + k m (or Ctrl +Shift + P and type "change language mode")` with a file of the type you're associating open.
In the first selections will be the option "Configure File Association for 'x' " (whatever file type - see image attached). Selecting this gives you the option to choose the language and will then make the filetype association permanent.

This may have changed (probably did) since the original question and accepted answer (and I don't know when it changed) but it's so much easier than the manual editing steps in the accepted and some of the other answers, and totally avoids having to muss with IDs that may not be obvious.
Answer 2
In VScode, you can add persistent file associations for language highlighting to your settings.json file like this:
// Place your settings in this file to overwrite the default settings
{
"some_setting": custom_value,
...
"files.associations": {
"*.thor": "ruby",
"*.jsx": "javascript",
"Jenkinsfile*": "groovy"
}
}
You can use Ctrl+Shift+P (or View -> Command Palette from the menu) and then type settings JSON. Choose Preferences: Open Settings (JSON) to open your settings.json.
To find the proper language ID, use Ctrl + Shift + P (or View -> Command Palette from the menu) and then type Change Language Mode. You can see the language ID in the list, e.g. type docker to find the language ID for Docker files (dockerfile). In the first entry in the example above, .thor is the file ending, ruby is the language ID.
Is there any to revert/disable the newest change for the untitled tab name (https://code.visualstudio.com/updates/v1_42#_untitled-editor-improvements)
I would prefer to the untitled-1 than the first sentence line.
As your link says:
Note: If the first line is empty or does not contain any words, the
title will fall back to Untitled-* as before.
I don't think there is a way to disable it other than to have that first line blank until you do give it a name.
The request for a setting to disable the current functionality is tracked here: https://github.com/microsoft/vscode/issues/90378 (Config to limit/disable the new Untitled tab auto-naming) or https://github.com/microsoft/vscode/issues/90495
you could upvote that issue.
---------- update, coming in v1.43:
A new setting workbench.editor.untitled.labelFormat lets you control
whether untitled editors should use the file contents as the title or
not. Possible values are content or name. Configure
'workbench.editor.untitled.labelFormat': 'name' for the previous
behavior, where untitled editors would have a short title, such as
Untitled-1.
When pasting text into an untitled editor, VS Code now automatically
tries to detect the language mode from the first line of text. For
example, pasting XML will set the XML mode automatically upon paste if
the first line contains the typical XML header .
Now my default file type of Visual Studio Code is Plain Text.
If I save a new file with name like a.in, it will save as a.in.txt. I have to change the dropdown to All Files.
I find the same problems in github: 1, 2. However, they seem not solve my problem.
This is not possible in the general case in VSCode.
The issue is that you cannot assign "no extension" to a language, and as per the links you mentioned, the All Files (*.*) option is disabled by upstream (electron).
Therefore, you will either have to remove the extension manually, OR you can create the file first (using the terminal, Explorer, an extension, etc.) and then open that existing file.
There is a way to change the default extension (but not to All Files)
Add the following line to your settings.json
"files.defaultLanguage": "<language>",
Replace <language> with the language of your choice.
Now, whenever you make a new a file, the default file language will be <language>.
A special value for <language> is ${activeEditorLanguage} which is the language of the file last opened (useful if, say, you copy a piece of code from one file to save as another).
Unfortunately, this does not fully answer the question, but provides a partial solution.
How would you filter the files shown in the folder view in Visual Studio Code?
Reference: Filter files shown in folder
Hiding files and folders
The files.exclude setting lets you define patterns to hide files and folders from several places in VS Code like the explorer and search. Once defined, files and folders matching any of the patterns will be hidden.
{
"files.exclude": {
"**/*.js": true
}
}
Hide derived resources
If you use a language that compiles to another file at the same location of the source file, like TypeScript does to JavaScript, you can easily set an expression to hide those derived files:
"**/*.js": { "when": "$(basename).ts"}
Such a pattern will match on any JavaScript file (**/*.js), but only if a sibling file with the same name and extension, *.ts in this example, is present. The same technique can be used for other transpiled languages, like Coffee Script or Less/Sass, too.
Source: VS Code v0.5.0 (July 2015)
In version after VScode 1.70 (July 2022) all you need to do is press Ctrl+F or F3 to search.
Please refer following post
Searching in Explorer panel after VSCode 1.70
Only applicable for v1.69 and below.
Step #1
Click on Explorer window. This is critical as without focus on Explorer it will not work.
Step #2
Start Typing name you want to filter. It's weird that there is no textbox to take input but... take a leap of faith and type. You will see your typed text in top-right corner in brown background. Now hover on that text.
Step #3
Click on 3 stacked lines to filter..
They look like hamburger menu but they are not. They are saying if it's filtered or not. They are toggled between filtered and just highlight. So, make sure they are like inverted pyramid.
That's it. It should be filtered now.
If you only want to change the setting for this project, then do the following:
File > Save Workspace As > ... enter your {project name}
Then open file: {project name}.code-workspace
And update section settings.
Sample:
{
"folders": [
{
"path": "."
}
],
"settings": {
"files.exclude": {
"**/*.log": true
}
}
}
VScode 1.70 (July 2022) should improve on this "tree filter" feature.
(Available today in Code insiders)
See issue 70646 and PR 152481:
Support find widget in lists/trees
This PR replaces the existing list/tree type filter:
with an bona fide find widget:
While a seemingly simple change, this has some (desired) consequences when searching/filtering in trees. Namely:
We will restore simple keyboard navigation by default.
That is: pressing the letter A will focus the next element which starts with A.
Initiating a search operation requires pressing Ctrl-F or F3, like the editor.
While searching, focus is in the find input box as opposed to the list itself.
Pressing DownArrow will focus the first list element which was found.
We'll preserve all custom behavior of context keys, eg. used by the VIM extension).
In VIM, the pre-existing / command will trigger simple keyboard navigation, as opposed to opening the find widget.
The VIM extension has the option to change this behavior themselves.
And:
In general:
Keyboard navigation is now called type navigation
Filter on type is now called find mode, aligned with a new find concept
Settings
workbench.list.keyboardNavigation has been renamed to workbench.list.defaultFindMode
workbench.list.automaticKeyboardNavigation has been deleted
Commands
list.toggleKeyboardNavigation has been renamed to list.triggerTypeNavigation
list.find has been added
list.closeFind has been added
list.toggleFilterOnType has been renamed to list.toggleFindMode
Context Keys
Mainly used by the vim extension:
listSupportsKeyboardNavigation has been renamed to listSupportsTypeNavigation
listAutomaticKeyboardNavigation has been renamed to listTypeNavigationMode
"With the focus on the File Explorer start to type part of the file name you want to match.You will see a filter box in the top-right of the File Explorer showing what you have typed so far and matching file names will be highlighted."
"Hovering over the filter box and selecting Enable Filter on Type will show only matching files/folders."

IN Eclipse i want to chnage the default editor of some .htm files.
If i try to go to FIle Association and assiciate the default editor then file gets opened in that new editor but i don't get the syntax highlighting.
The solution is that the file association is locked ny some plugin editor
Preferences -- Context type----text ----Your editor -- reomve the extension
But i get the .htm(locked) so i cant remove it.
http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.platform.doc.user%2Freference%2Fref-content-type.htm
Note: Certain items will be marked as "locked". An item is locked if
it is one of the associations provided by the plug-in that declares
the content type. In other words, you can remove only user-contributed
associations.
Is there any way to remove those locks even thought it can be hackish way but i want to do it
You don't need to "unlock" an existing association to add a new association and make it the default.
Add a new association via the "Add" button
Select the new entry
Hit the "Default" button to make your new entry the default editor
Could it be, that you want to change the "File Association"? This can be done in General / Editors / File Associations. BUT Eclipse uses at least one default-editor and this is the reason for the "locked"-message in the "Content Types". You could set the "Text Editor" to all unwanted types. Looks like a workaround, but makes sense, because it is the same as the file associations of your operating system, that asks you for the program to display the file.
Another question is, why do you want to unlock or remove the "Content Type"? Does it change anything in the Eclipse logic?
Go see this answer from "Greg Desmarais" (assign the desired editor to "default")
