I think it's clearer if only the actual demos started with `demo_`,
so I renamed `demo_helpers.sh` to just `helpers.sh`.
`demo_resolve_conflict.sh` should match `resolve_conflicts.png` (with an s).
The demos don't need to be animated - the user wouldn't miss anything
if they skipped to the end. So let's just show the full output so the
user can read through it at their own pace. We could use plain text,
but I think the colors are helpful, so I went with screenshots.
Closes#166.
The default log output of showing all commits is not very useful when
contributing to an existing repo. Let's have it default to showing
commits not on any remote branch instead. I think that's the best we
can do since we don't have a configurable main branch yet, and we
don't even have per-repo configuration..
Closes#250.
It can take quite a while to record a demo. This patch adds a `--fast`
flag for reducing delays to a tenth of the usual. You can play the
recording with `asciinema play -s 0.1` to get close-to-normal speed
(except that command delays will be slower). That way you can adjust
timings with shorter round-trips.
According to asciinema.org, it should be possible to change the title
after uploading, but I couldn't figure out how to do that. Let's set
it when creating the recording. That also means it's one less step to
perform when re-running scripts.
I find it frustrating to wait for the typing, but I need much more
time to think between commands (and users who are new to the tool
surely need even more time).
Most commands are non-interactive, so this reduces duplication. We can
add another function for running a command and not waiting for a
prompt when we need it.
