Question: Lookup external module names

[basarat]

I already provide a decent experience for relative paths /~https://github.com/TypeStrong/atom-typescript#relative-paths

Want to expand it to also list the available external module declarations. But struggling to find the different between these two types:

declare module foo{
}

vs

declare module 'foo'{
}

Is there some LS API I could use to just get 'foo' and not foo?

Note: I have access to program so if its not possible using LS feel free to guide me a bit toward the program based solution 🌹

What I've look at : they both seem to be SyntaxKind.ModuleDeclaration

[mhegazy]

yes. the external module have a name that is SyntaxKind.StringLiteral. so the check would be

1. in Ambient context
2. name of the module is stringLiteral

I had a PR (#2173) that did external module name completions, this might be helpful.

PR helped a lot. Thanks ❤️

export function getExternalModuleNames(program: Program): string[] {
    var entries: string[] = [];

    program.getSourceFiles().forEach(sourceFile => {

        // Look for ambient external module declarations
        forEachChild(sourceFile, child => {
            if (child.kind === SyntaxKind.ModuleDeclaration && (<ModuleDeclaration>child).name.kind === SyntaxKind.StringLiteral) {
                entries.push((<ModuleDeclaration>child).name.text);
            }
        });
    });

    return entries;
}
