VScode snippets
Development of this extension is done in Visual Studio Code. To make it slightly easier and faster to type the Lua calls a set of code snippets are made available. They can be downloaded from Visual Studio Marketplace: Lua snippets for Wikimedia or from GitHub: jeblad/vscode-wikimediafunctions-snippets. It is also possible to do a direct install from inside VScode
ext install jeblad-3.WMFsnippets
Due to lack of a proper Lua intellisense it only works sort of halfway.
