Format APEX code Visual Studio code

Personally, I use the following extensions for vscode: Salesforce Extensions for VS Code - A package of Salesforce made extensions for editing code. Provides syntax highlighting & will recognize salesforce files based on their extension. Pretty much a must have for working with sfdx. Apex PMD - provides a tool to analyze code based on a ruleset. Comes with its own ruleset based on java best practices. Useful tool for new developers or old developers working with a codebase which could use a tuneup. It can be modified further to fit your needs. I asked about supporting an official formatter & was told that it was supported, via a version of prettier. Installation To install the Prettier Apex plugin: Navigate to the top-level of your project Check if your project contains the package.json file. If not, run: npm init and accept all the default options.  m install --save-dev --save-exact prettier prettier-plugin-apex. You must create a configuration file .prettier in the root of your project. If you’d like to know more about formatting options of Prettier, read other config options.

    { "trailingComma": "none", "overrides": [ { "files": "**/lwc/**/*.html", "options": { "parser": "lwc" } }, { "files": "*.{cmp,page,component}", "options": { "parser": "html" } } ] }

NOTE: The "trailingComma": "none" setting is required for Aura.

• After creating the local configuration file, install the Prettier extension for VS Code.
  
• I'd install the Salesforce extensions for vscode, or some of the individual components. They provide hinting and syntax features which make editing files much easier.
  
• 2020: Mavensmate is no longer around. The Salesforce provided extensions work well with SFDX and should meet any other need you have. There is no formatter included in the sfdx package.
