LTEX Extension for VS Code: Grammar/Spell Checker Using LanguageTool with Support for LATEX, Markdown, and Others
LTEX provides offline grammar checking of various markup languages in Visual Studio Code using LanguageTool (LT). LTEX currently supports BibTEX, ConTEXt, LATEX, Markdown, Org, reStructuredText, R Sweave, and XHTML documents. In addition, LTEX can check comments in many popular programming languages (optional, opt-in).
The difference to regular spell checkers is that LTEX not only detects spelling errors, but also many grammar and stylistic errors such as:
This is an mistake.The bananas is tasty.We look forward to welcome you.Are human beings any different than animals?
A classic use case of LTEX is checking scientific LATEX papers, but why not check your next blog post, book chapter, or long e-mail before you send it to someone else?
Find more information and documentation about LTEX on the official website.
LTEX is a successor (since it's a fork) of the abandoned LanguageTool for Visual Studio Code extension by Adam Voss†.
