Get Visual Studio Code snippets scope programmatically using API - visual-studio-code

Question

Can I get the list of the available scopes for snippets?
Is there any native functionality that would control what files to create and where?

Answer 1

Snippets are scoped to languages and introduced to VS Code as global or local to a workspace. Languages can be contributed to VS Code by exceptions. Typically by declaring a language in the package.json, adding a syntax and snippet files. Update:
Here is the guide how to add a snippet to any language via your extension. If you follow the guide and add a snippet to the current workspace, you will notice that the file with extension .code-snippets gets created under the .vscode folder in the workspace. Therefore you can enumerate all such files using the vscode.workspace.workspaceFolders and fs.readDir APIs.
vscode.workspace.workspaceFolders!.forEach(workspaceFolder => {
const snippetFiles = fs.readdirSync(path.join(workspaceFolder.uri.fsPath, '.vscode'))
.filter(el => /\.code-snippets$/.test(el));
});
Similarly, the global snippets get added as .code-snippets files into the user profile folder - on Windows it looks like this: C:\Users\currentUser\AppData\Roaming\Code\User\snippets\*.code-snippets. Both locations you can scan for *.code-snippets files as well as programmatically add such files to those folders.
Here is the documentation how to add snippets to a scope via a file. There does not seem to be any public API to enumerate all such snippet files in a programmatic way.
But if you want to retrieve list of the languages in the screenshot you posted, use this API:
vscode.languages.getLanguages()
It could help if you explained what are you trying to achieve. Do you want to find where a particular snippet is coming from to change it? Do you want to add a snippet to a language in this list? Or to a language that is not on this list?
