I installed the GitHub Actions extension for VS Code and it started
giving me lint warnings about this line:
a9adb4175c/.github/workflows/rust-ci.yml (L99)
Using an env var to track the state of individual steps was not great,
so I did some research about GitHub actions, which led to the discovery
of combining `continue-on-error: true` with `if .. steps.STEP.outcome ==
'failure'...`.
Apparently there is also a `failure()` macro that is supposed to make
this simpler, but I saw a number of complains online about it not
working as expected. Checking `outcome` seems maybe more reliable at the
cost of being slightly more verbose.
https://github.com/openai/codex/pull/855 added the clippy warning to
disallow `unwrap()`, but apparently we were not verifying that tests
were "clippy clean" in CI, so I ended up with a lot of local errors in
VS Code.
This turns on the check in CI and fixes the offenders.
I noticed that sometimes I would enter a new message, but it would not
show up in the conversation history. Even if I focused the conversation
history and tried to scroll it to the bottom, I could not bring it into
view. At first, I was concerned that messages were not making it to the
UI layer, but I added debug statements and verified that was not the
issue.
It turned out that, previous to this PR, lines that are wider than the
viewport take up multiple lines of vertical space because `wrap()` was
set on the `Paragraph` inside the scroll pane. Unfortunately, that broke
our "scrollbar math" that assumed each `Line` contributes one line of
height in the UI.
This PR removes the `wrap()`, but introduces a new issue, which is that
now you cannot see long lines without resizing your terminal window. For
now, I filed an issue here:
https://github.com/openai/codex/issues/869
I think the long-term fix is to fix our math so it calculates the height
of a `Line` after it is wrapped given the current width of the viewport.
