VSCode-Hovering-Dictionary

Hovering-Dictionary is a VSCode extension for looking up words your mouse cursor is indicating.

This extension is inspired by Mouse Dictionary (MIT License, wtetsu, 2018).

Features

Fast looking up words with case sensitivity

(Note that this demonstration was held after importing 英辞郎(EIJIRO) dictionary data, see #importing-dictionaries. Many expressions such as "on one's own" are NOT included in the default dictionary.)

Mouse Dictionary provides a very fast and flexible way to refer to a dictionary. By partially using the code in this Chrome extension, I realize its similar function in VSCode!

• Fast reference: It usually takes only less than 1 ms to obtain the reference to the words your mouse indicates.
• Case-sensitive search: camelCase -> camel case, snake_case -> snake case, etc...
• Expandability: You can import many other dictionary data if you want.

You can toggle the visibility of the hover by simply clicking the right side button or the command hovering-dictionary.toggle-hover-visibility. I recommend registering this command hovering-dictionary.toggle-hover-visibility as a short-cut key.

Importing dictionaries

This extension includes the default dictionary provided in ejdict-hand (Public Domain). In addition, you can import any dictionary formats you could import in Mouse Dictionary.

You can import the dictionaries via the command hovering-dictionary.import-dictionary.

This page which shows much information about some kinds of available dictionary files is also helpful.

How to work?

This extension uses Level as a database in the background. The dictionary data is registered and kept in the storage directory the VSCode allows; e.g. C:\Users\hoge\AppData\Roaming\Code\User\globalStorage\take-me1010.hovering-dictionary if you are a Windows user.
