qfmt — Quick Formatter

Lightweight, fast, zero-config code formatter for VS Code. Clean up your code in one keystroke. No plugins, no dependencies, no configuration needed.

Why qfmt?

Most formatters are heavy, language-specific, and require complex configuration files. qfmt is different:

• Zero config — Works out of the box, no .prettierrc, no .editorconfig needed
• Any language — JavaScript, TypeScript, Python, Java, C#, Go, Rust, HTML, CSS, Markdown, and more
• Blazing fast — Pure text transformations, no AST parsing, no external processes
• Non-destructive — Only cleans formatting issues, never changes your logic

Features

Trim Trailing Whitespace

Removes invisible spaces and tabs at the end of every line. Keeps your diffs clean and your code consistent.

Remove Consecutive Blank Lines

Collapses 3+ blank lines into just one. No more huge gaps in your files.

Ensure Final Newline

Automatically adds a newline at the end of the file if missing. Follows POSIX standards.

Sort Imports (JS/TS)

Alphabetically sorts import and require() blocks. Groups are preserved and sorted independently.

Convert Indentation

Switch between tabs and spaces instantly across your entire file.

Format on Save

Enable automatic formatting every time you save. Set it once, forget about it.

Available Commands

Open the Command Palette (Ctrl+Shift+P) and type qfmt:

Keyboard Shortcut

Examples

TypeScript — Before

import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { ActivatedRoute } from '@angular/router';


import { Observable } from 'rxjs';



export class AppComponent {
    name:   string;


    constructor(private http: HttpClient) {
        this.name = 'hello';
    }
}

TypeScript — After Ctrl + Alt + Q

import { ActivatedRoute } from '@angular/router';
import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

export class AppComponent {
    name:   string;

    constructor(private http: HttpClient) {
        this.name = 'hello';
    }
}

Trailing whitespace removed, consecutive blank lines collapsed, imports sorted alphabetically.

Java — Before

import java.util.Map;
import java.io.File;
import java.util.List;
import java.util.ArrayList;


import java.io.IOException;



public class UserService {


    private List<String> users;



    public UserService() {
        this.users = new ArrayList<>();
    }
}

Java — After Ctrl + Alt + Q

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

public class UserService {

    private List<String> users;

    public UserService() {
        this.users = new ArrayList<>();
    }
}

Imports sorted, trailing whitespace cleaned, blank lines normalized.
