Summary

This needs lots of work. Posting so @mharbison and others can see what
I've been hacking on.

To build:

$ cd rust/hgcli
$ pyoxidizer build

Things currently blow up in many different ways at run time.

This is in no way suitable for review or landing. Many things are missing. Binaries segfault on startup (which is likely a PyOxidizer bug, ugh).

durin42 added a subscriber: mharbison72.Nov 15 2019, 12:39 AM

also fyi @mharbison72 since it looks like the @ in the commit message didn't work?

indygreg abandoned this revision.Dec 23 2019, 12:42 PM

D7450 is the successor to this patch.
