[Question] How to programatically access New Unsaved File

[jongeller]

Hi all, trying to get access through the vscode namespace to a new tab (unsaved) editor in the active window.

I would like to create a new document, but it needs to remain unsaved. I cannot find a way to programmatically set the content of this document while it is in a unsaved state.
I have used: commands.executeCommand("workbench.action.files.newUntitledFile") but there seems to be no way focus on that new editor window (until saved) to then add content to the document.
When I create a new temp file and open it with: workspace.openTextDocument(path) The file is already saved.

Thanks!

I believe I just answered your question over on StackOverflow

Please let me know if that is what you are looking for or if anything is unclear.

Thanks.

@mjbvz - thanks! That is what I was looking for, I'll follow if I have any questions.

@mjbvz is there any way to do this without providing a path to save the unsaved file to? I'd like force the prompt for a save location when a user tries to save the file, instead of forcing one to be provided.

[jongeller]

@mjbvz - just pinging again, incase this got lost over the weekend.

I'm not sure if we have a good api story for that flow.

@jrieken Do you have any thoughts on how he could accomplish this using the existing apis?

[jongeller]

Just to add a bit more. Is there anyway to leverage "workbench.action.files.newUntitledFile"? I've been trying to discern what parameters may exist, but no luck yet.

@jongeller You can call openTextDocument with an URI using the untitled-scheme. That will create a new document, like so:

return workspace.openTextDocument(Uri.parse('untitled:c:/test/files.js').then(doc => {
	assert.equal(doc.uri.scheme, 'untitled');
	assert.ok(doc.isDirty);
});

[jongeller]

@jrieken right, which was what @mjbvz showed me over on stackoverflow, however, I was asking if it was possible to use the API to open a new tab, populate it, but not pre-set a save path. This way, on save, the user is prompted to provide a path.

looks like these two items were added to open issues internally and externally, but haven't been addressed in a couple months:
#12283
and
hoovercj/vscode-octo#11

[jrieken]

Yes #12283 is what you want
