Auto Comment Blocks

Provides block comment completion for Javadoc-style multi-line comments and single-line comment blocks for most officially supported languages.

MAJOR CHANGES IN 1.0 UPDATE (Please Read)

A lot has changed in this update. Please open issues for any bugs you encounter.

Single-line Comment Blocks

You can now use single line comment blocks for languages with //, #, or ; style single line comments. Press Shift+Enter while on a commented line to insert a new commented line with the same level of indentation. See the Settings section for how to change the behavior so that Enter inserts a commented line while Shift+Enter breaks out of the comment block (this only works correctly for a subset of languages right now).

The Language Support section shows which languages are supported. See the Settings section for how to add single line comment support to languages that are not officially supported.

Multi-line Comment Blocks

This feature has not changed, but support has now been added for Less, Objective-C/C++, and Swift.

Usage

Demo

Javadoc-style comment blocks

Type /** to start a block comment, then hit the Enter key, and the extension will close the block. While inside the comment block, the extension will insert an asterisk at the start of every new line, and align the comment, respecting indentation.

QDoc-style (Qt) comment blocks

Use /*! in C/C++ files to start a QDoc comment block.

New: "single-line" block comments

You can insert single line comment blocks for languages with //, #, or ; style single line comments. Press Shift+Enter while on a commented line to insert a new commented line with the same level of indentation. See the Settings section for issues and more options.

Settings

Reload the extension after changing any settings.

  • auto-comment-blocks.singleLineBlockOnEnter: If enabled, pressing Enter inserts a new commented line at the same indentation, and pressing Shift+Enter breaks the comment block.
    • Caution: This feature is buggy in many languages (see Issues section), but it seems to work fine for C, C++, Go, Less, PHP, Ruby, and Sass.
  • auto-comment-blocks.disabledLanguages: Add languageIds here to disable any comment completion for that language.
  • auto-comment-blocks.slashStyleBlocks: Add languageIds here to enable '//' and '///'-style single line comment blocks for that language.
  • auto-comment-blocks.hashStyleBlocks: Add languageIds here to enable '#'-style single line comment blocks for that language.
  • auto-comment-blocks.semicolonStyleBlocks: Add languageIds here to enable ';'-style single line comment blocks for that language.

Issues

  • Single-line blocks using Enter: if you enable the singleLineBlockOnEnter setting, there are a few things to keep in mind:
    • It seems to work find for C, C++, Go, Less, PHP, Ruby, and Sass.
    • It doesn't work at all for Python, JavaScript, and TypeScript.
    • For every other language, if you press Tab immediately after breaking out of a comment block, it will insert a commented line, for some unknown reason.
  • Sometimes multi-line completion/aseterisk insertion doesn't work. The reason is still unknown. It may go away if you reload your workspace.
  • Currently, VS Code only allows extensions to overwrite, instead of modify, existing language configurations. This means that this extension may clash with another extension that overwrites the same language configurations, causing one or both not to work. In that case, uninstalling this extension is the only option for now.

Please create an issue in the repository if you find any bugs, or have questions or feature requests.
