I have a question with VSCode. I developed tests with Cypress and VS didn't show any problem. In fact, this tests are working right now. However, VS Code shows a lot of stranges errors today. For example 'describe' is not defined. (no-undef)' or 'Expected indentation of 4 spaces but found 8. (indent)' as you can see in the image.
I did not change the VS Code Settings. Why is it happening?
UPDATE: I think the problem is the new version of Cypress 7.5, but i have not found a solution yet
I tried to fix that with this steps:
File / Preferences / Settings then Text Editor (or just search for 'tab' in the search settings box)
Then remove the tick from the following settings:
Insert Spaces
Detect Indentation
But it didnt' work. FInally, I had to remove the JS6 VS Extensions and this errors dissapeared.
That was My problem too, The exact error was:
Expected indentation of 4 spaces but found 6. eslint(indent)
And to fix that, I just let ESLint knows that "I don't want it to take care of those indentations".
There're two approaches for that (base on the eslint docs):
1. Using configuration comment
Put the following comment at the very top of each file you want that indentation to be ignored:
/* eslint-disable indent */
2. Using configuration file
To disable the indentation rule for a group of files (ex. test.js or spec.js), use the following code snippet in the .eslintrc file:
{
/* Whatever's here */,
"overrides": [
{
"files": ["*-test.js","*.spec.js"],
"rules": {
"indent": "off"
}
}
]
}
For every typescript file visual studio code uses an auto indentation of 8 spaces. This is a bit too much for my taste but I can't find where to change it.
Maybe it's available as a setting but under a different name as I can't find anything related to indentation.
UPDATE
I'm currently using the Prettier code formatter and that solves all formatting problems by auto formatting on save (if there is no syntax error)
In the toolbar in the bottom right corner you will see a item that looks like the following:
After clicking on it you will get the option to indent using either spaces or tabs. After selecting your indent type you will then have the option to change how big an indent is. In the case of the example above, indentation is set to 4 space characters per indent. If tab is selected as your indentation character then you will see Tab Size instead of Spaces
If you want to have this apply to all files and not on an individual file basis, then override the Editor: Tab Size and Editor: Insert Spaces settings in either User Settings or Workspace Settings depending on your needs
Edit 1
To get to your user or workspace settings go to Preferences -> Settings. Verify that you are on the User or Workspace tab depending on your needs and use the search bar to locate the settings. You may also want to disable Editor: Detect Indentation as this setting will override what you set for Editor: Insert Spaces and Editor: Tab Size when it is enabled
You can change this in global User level or Workspace level.
Open the settings: Click the gear on the bottom left, then click Settings as shown below.
Then, do the following 2 changes: (type tabSize in the search bar)
Uncheck the checkbox of Detect Indentation
Change the tab size to be 2/4 (Although I strongly think 2 is correct for JS. Haha :))
To change the indentation based on programming language:
Open the Command Palette (CtrlShiftP | macOS: ⇧⌘P).
Type and select: Preferences: Configure Language Specific Settings... (command id: workbench.action.configureLanguageBasedSettings).
Select a programming language (for example TypeScript).
If Settings menu is opened (since 1.66.0):
4. Press → to place the cursor right beside the language filter (e.g. #lang:typescript).
5. Type Tab Size and enter your preferred value in the text box.
If settings.json file is opened:
4. Add this code:
"[typescript]": {
"editor.tabSize": 2
}

Code Formatting Shortcut:
VSCode on Windows - Shift + Alt + F
VSCode on MacOS - Shift + Option + F
VSCode on Ubuntu - Ctrl + Shift + I
You can also customize this shortcut using preference setting if needed.
column selection with keyboard
Ctrl + Shift + Alt + Arrow
You might also want to set the editor.detectIndentation to false, in addition to Elliot-J's answer.
VSCode will overwrite your editor.tabSize and editor.insertSpaces settings per file if it detects that a file has a different tab or spaces indentation pattern. You can run into this issue if you add existing files to your project, or if you add files using code generators like Angular Cli. The above setting prevents VSCode from doing this.
In my case "EditorConfig for VS Code" extention is overriding VSCode settings.
If you have it installed, then check .editorconfig file in the root folder of the project.
Here is an example config. The "indent_size" sets the number of spaces for a tab.
# editorconfig.org
root = true
[*]
indent_style = space
indent_size = 4
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true
[*.md]
trim_trailing_whitespace = false

Hope someone sees this.
Simplified explanation with pictures for those that googled "Change indentation in VS Code"
Step 1: Click on Preferences > Settings
Step 2: The setting you are looking for is "Detect Indentation", begin typing that. Click on "Editor: Tab Size"
Step 3: Scroll down to "Editor: Tab Size" and type in 2 (or whatever you need).

Example of my changes
To set all existing files and new files to space identation to 2 just put it in your settingns.json (in the root of json):
"[typescript]": {
"editor.defaultFormatter": "vscode.typescript-language-features",
"editor.tabSize": 2,
"editor.insertSpaces": true,
"editor.detectIndentation":false
}
you can add the language type of the configuration:
"[javascript]": {
"editor.tabSize": 2,
"editor.insertSpaces": true,
"editor.detectIndentation":false
}
Setting the indentation in preferences isn't allways the solution. Most of the time the indentation is right except you happen to copy some code code from other sources or your collegue make something for you and has different settings. Then you want to just quickly convert the indentation from 2 to 4 or the other way round.
That's what this vscode extension is doing for you
Step 1: Open settings.json in vscode
Step 2: Add the lines as below for the programming language (an example is below)
For typescript and javascript
"editor.detectIndentation": false,
"[typescript]": {
"editor.defaultFormatter": "vscode.typescript-language-features",
"editor.tabSize": 2,
"editor.insertSpaces": true,
"editor.detectIndentation":false
},
"[javascript]": {
"editor.tabSize": 2,
"editor.insertSpaces": true,
"editor.detectIndentation":false
}
Problem: The accepted answer does not actually fix the indentation in the current document.
Solution: Run Format Document to re-process the document according to current (new) settings.
Problem: The HTML docs in my projects are of type "Django HTML" not "HTML" and there is no formatter available.
Solution: Switch them to syntax "HTML", format them, then switch back to "Django HTML."
Problem: The HTML formatter doesn't know how to handle Django template tags and undoes much of my carefully applied nesting.
Solution: Install the Indent 4-2 extension, which performs indentation strictly, without regard to the current language syntax (which is what I want in this case).
I wanted to change the indentation of my existing HTML file from 4 spaces to 2 spaces.
I clicked the 'Spaces: 4' button in the status bar and changed them to two in the next dialog box.
I use 'vim' extension. I don't how to re-indent without vim
To re-indent my current file, I used this:
gg
=
G
Check tabWidth if you are using a formatter, that was the issue in my case. It represents the number of spaces used in tabs.
Adding on: yes, you can use the bottom-right UI to configure the space settings. But if you have existing code that's not formatted to the new spacing, then you can right-click anywhere within the file and click Format Document. Took me a while to figure this out until I stumbled on this issue.
Format Document menu
For me it was docs-markdown andDocs Authoring Pack. Microsoft's many modules messing with each other yet again! Disabled the extensions and now good to go again 😀
The Problem of auto deintending is caused due to a checkbox being active in the settings of VSCode.
Follow these steps:
goto preferences
goto settings
search 'editor:trim auto whitespace'
Uncheck The box
The following search-and-replace regex changes the number of spaces per indentation level from 4 to 2 in existing files. It's relatively easy to understand, reliable, and doesn't require installing anything.
Instructions
Press CtrlH (or ⌥⌘F on macOS).
Make sure regex matching is on by clicking on the .* button in the search popup or pressing AltR (or ⌥⌘R on macOS).
In the Find field, enter ^(?:( ) )?(?:( ) )?(?:( ) )?(?:( ) )?(?:( ) )?(?:( ) )?(?:( ) )?(?:( ) )?(?:( ) )?
In the Replace field, enter $1$2$3$4$5$6$7$8$9
Finally press CtrlEnter (or ⌘Enter on macOS) to apply to the current file.
You could also use this in the Search pane on the left to do this across all files in your project. However, note that this should only be run once per file. It will mess up the indentation of files that already use 2 spaces.
Extra Credit: How It Works
The way the regular expression works is it matches groups (?: ... ) of four spaces at a time at the beginning ^ ... of each line, only capturing ( ... ) the first two spaces. Each indentation level is optional ... ?, so it works for as many indentation levels as the pattern is repeated and there are in each line. Then it replaces the whole pattern with only the captured spaces $1, $2, ..., effectively replacing every four-space indentation level with two spaces.
This pattern only works up to 9 indentation levels (I'm not sure if $10 would work, but if so this could be expanded indefinitely).
Extra Extra Credit: Extending
You could adapt the pattern to decrease the number of spaces per indentation level in a file from any original number to another lower target number.
Put the target number of spaces inside the inner parenthesis. Then, put the remaining original number of spaces in the outer parenthesis, so the total number of spaces in the pattern is the original.
For example, if you want to change the indentation level from 6 to 4, repeat this search pattern as many times as you like:
^(?:( ) )? or ^(?:( {4}) {2})?
And use the same number of $1, $2 in the replacement pattern.
First, check if you have installed "EditorConfig for VS Code". It was overriding my editor settings. I spent all day correcting this problem.
In the project find .editorconfig file and ones changed there it will work.
I like these settings for indentation you can modify them according to need.
You can open VScode setting.json file by typing CTRL+SHIFT+P and paste below the JSON setting
setting.json
"[javascript]": {
"editor.defaultFormatter": "vscode.typescript-language-features",
"editor.formatOnSave": true,
"editor.tabSize": 4,
"editor.insertSpaces": false,
"editor.detectIndentation": false,
"editor.wrappingIndent": "deepIndent",
"editor.autoIndent": "full"
},
"[typescript]": {
"editor.defaultFormatter": "vscode.typescript-language-features",
"editor.formatOnSave": true,
"editor.tabSize": 4,
"editor.insertSpaces": false,
"editor.detectIndentation": false,
"editor.wrappingIndent": "deepIndent",
"editor.autoIndent": "full"
}
With VSCode 1.75 (Jan. 2023), indentation is also customizable on VSCode terminals, not just VSCode views.
See issues 170432: "Add a terminal tab stop size (editor.tabSize) setting"
When a tab is printed in the terminal, it has a tab size of 8 spaces, regardless of the tab size setting.
Therefore, PR 170733 adds a new setting:
terminal.integrated.tabStopWidth: The number of cells in a tab stop
I am trying to generate a PDF file from an html content using FPDF
$this->pdf->AddPage();
$html = "Hello World";
$footer = "Footer";
$this->pdf->WriteHTML($html);
$this->pdf->SetXY(1,255);
$this->pdf->MultiCell(208, 20, $footer, 0, "C", false, 0, '','',true,0,true,true,0,'B',false);
The generated file contains a vertical line on the top of the page (above Hello World). After few tests I found out that it's added by AddPage(), I get that it's sort of a seperator of pages but I don't want to keep it and didn't find how to remove it.
Also, it doesn't seem like a common issue so I don't know if I'm missing something...
I think you are using TCPDF instead of FPDF. So just disable the automated page header via the setPrintHeader() method.
Open the api's code, go to the AddPage() function and modify it...remove the line that is being added.
I changed the user setting from preference and saved it. Then i tried to open editor but i get the error message. So i uninstalled and installed it again. Though, no use. Also the path mentioned in the error message also is not there.
The error message is:
Error trying to parse setting: Trailing comma before closing bracket in C:\Users
Rajanand\AppData\Roaming\Sublime Text 2\Packages\User\Preferences.sublime-settings:5:1
What am I missing here?
Go to Preferences > Settings - User. AppData is hidden by default in Windows, show with the explorer's folder options.
Your problem is that you have an extra comma somewhere in that file. Remove the comma from the last setting in any list. Without seeing that file, I can not tell you where exactly. Here are examples:
{
setting1,
setting2,
last_setting,<-- remove
}
Remove the comma from the last setting.
or
{
setting1,
setting2:
[
setting2_item1,
setting2_last_item,<-- remove
]
}
Remove the comma from setting2_last_item.
or
{
setting1:
[
setting1_item
],
setting2:
[
setting2_item
],<-- remove
}
Remove the comma after setting2's list.
The above answers helped me out on sublime text 3
But just wanted to add this...
For newbies like me, if you want to add your custom settings and you tried adding it to the Preference file and you're getting the error too... In my case I did like the following...
{
"ignored_packages":
[
"Vintage"
], // <-- I put the comma there so I can add the below, new setting.
"tab_size": 2 //My new setting
}
