plots: support opening plots file directly in the browser #5584

skshetry · 2021-03-09T16:20:21Z

$ dvc plots show --open

I don't know if this is that useful, but I think this does save some time (I was feeling the need when I was going through example-get-started).

Alternative:

No way to be compatible across different platforms. For me on Linux, it's following:

$ dvc plots show | xargs xdg-open

Working on macOS and on Windows (cc @jorgeorpinel?) confirmation would be great.

❗ I have followed the Contributing to DVC checklist.
📖 If this PR requires documentation updates, I have created a separate PR (or issue, at least) in dvc.org and linked it here.

Thank you for the contribution - we'll try to review it as soon as possible. 🙏

@skshetry There doesn't seem to be any comments/requests from users thus far, worried that we are adding dead code that no one is going to use. Though it is possible that people don't know they want it.

My workflow for this is to use Cmd (~Ctrl on Mac) + click the link DVC prints - it opens it automatically in the browser. Not saying that this option is not needed, just sharing my thoughts on why this feature didn't cross my mind I guess. I wonder how many users are familiar with hot keys in their terminals.

I would add --open to tests/unit/command/test_plot.py. Also, we have live command that produces HTML. Though the latter can be handled in other issue, as it seems we could share some options between plots and live.

I think it's a nice idea, although I guess it's a bit of an anomaly since no other commands open up anything outside the terminal. I would use it! Anything to avoid using my trackpad/mouse. It's also possible that some users are a bit confused by seeing a file:// url and don't realize it should be opened in the web browser. But I have no strong feelings on this, so feel free to drop it if it feels unnecessary.

dvc/command/plots.py

-
-            logger.info(f"file://{path}")
-
+            url = f"file://{path}"


This might need to be quoted, will do in a separate PR.

I was thinking about adding --open option to test_plots_diff, this exceeds expectations!

@skshetry Btw, looks like even though the checkbox is ticket, the doc is missing?

I was not sure if this was going to merged. I have created the docs, thanks.

Working on macOS and on Windows (cc @jorgeorpinel?) confirmation would be great.

I'm on Windows but on WSL (non-GUI Ubuntu) and it fails there unfort:

$ dvc plots show --open train.json
file:///home/jop/DVC-repos/test/plots.html
Start : This command cannot be run due to the error: The system cannot find the file specified.
At line:1 char:1
+ Start "file:///home/.../plots.html"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Start-Process], InvalidOperationException
    + FullyQualifiedErrorId : InvalidOperationException,Microsoft.PowerShell.Commands.StartProcessCommand

On Windows / Cmder (Git Bash) it works for me! But only from a DVC project dir.

Minor: for some reason if you run it outside a DVC project it get's stuck (while on Linux that seems to work regardless of where you are).

jorgeorpinel · 2021-03-17T19:01:15Z

Same on regular Command Prompt (cmd):

plots show (in general) gets stuck if run outside a DVC project dir.
plots show --open works from within a DVC project 🙂

skshetry · 2021-03-22T16:43:12Z

@jorgeorpinel, opened #5670 to address the WSL related issue.

To open into a browser in the host computer, you have to specify BROWSER envvar, something like follows:

export BROWSER=/mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe

and then you can do --open and it'll open in the specified browser. For me, it's terribly slow.

skshetry · 2021-03-22T16:44:17Z

@jorgeorpinel, for other issues, please open an issue as it needs more information on what's happening. Thanks. 🙂
