Help - can't open source member programmatically

[StuBramley]

Hi,
I'm developing an extension (essentially a port of an internal utility to VS Code) and have hit a problem I can't get to the bottom of when trying to get VS Code to open a source member..

The block of code I have to open the source member is essentially as follows - it's pretty much the example from here: https://codefori.github.io/docs/dev/examples/#get-members-and-streamfiles but with the uri creation decoupled from the openTextDocument method so I can debug the URI and log it out..

            const uri:vscode.Uri = vscode.Uri.from({
                scheme: 'member',
                path: `/${source_library_iasp}/${source_library}/${source_file}/${source_member}.${source_type}`,
                query: 'readonly=true' 
            });
            this.logger.getOutputChannel().append(`URI constructed: ${uri}`);
            try {
                const doc = await vscode.workspace.openTextDocument(uri);
            } catch(e) {
                this.logger.getOutputChannel().append(`DLS: Error retrieving member ${e}`);
            }

When this executes, the source member indicated does not open. The URI is logged out correctly and if I ctrl-click the URI in the output window, it then opens.. but not when the code above executes.. is there something obvious I'm doing wrong here? I can see that the source member has been copied to a temporary IFS file but it does not open in VS Code..
Any ideas gratefully received..

@StuBramley The naming of the openTextDocument API can be a bit misleading. All that one does is loads the document and gives you access to it as a TextDocument. There is another API to actually show it in the editor:

const doc = await vscode.workspace.openTextDocument(uri);
await vscode.window.showTextDocument(doc);

That worked perfectly - thank you.. maybe something to tweak in the example code in the documentation?

Great! Yes that would be a good clarification in the docs. Would you like to contribute that? If yes, you can do that here
