The link used here resolves with a 301 to the proper page for messaging usage, but not actually the 'messaging' section of that page. This commit provides a more direct link to the exact instructions.
This changes the entry-points in lib/auto so that clients never have to
handle magic-spoon. You can specify either a tape of code with a
position index or a preparsed hoon (presumably you ran +insert-magic
before parsing).
This stops slogging the tab completion and intead adds a +sole-effect
for tab completion output. This is morally correct, and it lets dojo
clients show tab completions how they want. For example, web dojo could
implement this as a drop-down box.
Another advantage is that this puts the rendering logic in drum, which
knows the width of the terminal. Thus, we can make sure each match
takes no more than one line by truncating with ellipses. If there's
only one match and it's already fully typed, then we display the whole
type.
It's useful to know what a function takes and produces, so this changes the autocomplete type prettyprinter to emphasize those. This also gives a nice syntax for molds. Examples:
```
-----
add {a/@ b/@} -> @
~zod:dojo> add
-----
term * -> @tas
~zod:dojo> term
-----
sign-transaction {tx/{nonce/@ud gas-price/@ud gas/@ud to/@ux value/@ud data/@ux chain-id/@ux} pk/@} -> @ux
~zod:dojo> sign-transaction🔑ethereum
-----
wind {a/(* -> *) b/(* -> *)} -> * -> ?({$give p/*} {$pass p// q/*} {$slip p/*})
~zod:dojo> wind
```
This is initial support for type-aware tab completion. When you hit tab, it tries to complete the word you're in the middle of using a face or arm in the subject at that point in the code. It also shows all possible matches and their associated types. It's nearly instantaneous. Notes:
- It advances to the longest common prefix, so if you hit tab on `ab` and the only possible results are `abcde` and `abcdz`, then it'll write `abcd` and print both out (with their types).
- If there are fewer than ten matches, it prints the type along with the face. Printing types is too slow to use all the time, but with 10 it's essentially instantaneous.
- The match closest in the subject to you (i.e. smallest axis number) is displayed lowest (closest to your focus).
Examples below, where `<TAB>` represents me hitting tab while my cursor is at that position (the line with the `<TAB>` is not preserved in the actual output).
```

Functionally, this is in a state where I'd be comfortable shipping it. It doesn't interfere with anything if you don't press tab, and it's perfectly OTA-able. I do think its output is a little verbose, but that can be tuned over time as people try it and determine what feels good in practice.
Additional notes:
- There are plenty of similar systems for other languages, but my most direct inspiration is Idris's editor tools. This is implemented for the dojo, but I actually want it in my editor, which is why the meat is all defind in a library. I've only tested on dojo one-liners, so I don't know the performance on large blocks of code.
- The default type printer isn't great for this use case. In particular,
- Cores should not print anything about their context
- The `#t/` should go away
- If it looks like a gate, we should print its return value
- Maybe special handling for molds, but if the above is done, then for example `bone` is `* -> @ud`.
- The worst part about our wing ordering is that it really screws up tab completion. You want to do `point.owner-address` instead of `owner-address.point` because that lets you type `point.ow<TAB>`. I weakly prefer reading it how we do it now, but it's really not great. You could do an (dojo-specific?) alternate syntax of `point;owner-address`; this is a simple transformation.
- Regardless of the above, this should handle the case where we're in the middle of defining a wing; it doesn't right now.
- When a variable is shadowed, we show both of them. We should probably show the shadowed one with a `^`.
- We probably shouldn't print out hundreds of results. Maybe just the closest 50 with ellipses.
- This gets you any face in your subject, regardless of whether its type is reasonable. We could limit that some by copying the `gol` logic in mint, so that if the pseudo-backward-inference engine happens to know what type it should be, you can filter the tab results according to if they nest in that type. This would be "strongly type-aware".

Re-implements the behavior of the previous azimuth-tracker as an app
that pokes and peers eth-watcher. Should have maintained identical
outward semantics to the original.
When configuring a watchdog on a path that already exists, we now
"overwrite" it, meaning we throw away all history and trawl the node
for logs again.
If the only config change is the url, however, we silently modify it,
and simply use it "from this point onward".
This matches the behavior of the original azimuth-tracker.
In order to give an initial response to incoming subscriptions (without
resorting to retrieving that data from chain again) we now store event
log history in state.
Instead of discarding pending-logs entirely after sending out updates,
we add them to the watchdog's history.
Just like pending-logs, we remove from the head during a rewind (though
not before exhausting the pending-logs).
Kicks the update timer on application start, then sets a new timer
whenever it's awoken. This aims to ensure eth-watcher never stops
looking for updates periodically.
No longer overwrite messages' timestamp on-receive, instead keeping whatever
timestamp was set by the sender.
This behavior matches that of the late Hall.

Uses the logic existing in azimuth-tracker to implement a new
eth-watcher, which can look at Ethereum nodes for _any_ events, as
opposed to exclusively a subset of the Azimuth contract's events.
Azimuth-tracker will be reimplemented as a dependent of this in
forthcoming commits.
These were deprecated in favor of azimuth-tracker in #1320.
(Azimuth-tracker, however, isn't a general-purpose Ethereum log watcher
tool. Commits to transform it into a more broadly useful tool are
forthcoming.)
Until now, clients of Jael have had to store the first-seen rift if they
want to reliably detect breaches. Otherwise, they would get a false
positive if they heard an old message about a breach (eg if you kick
azimuth-tracker). Clay and Gall did this correctly, but Ames did not.
Jael already maintains this state, so I added a notification to the
existing subscription that happens whenever it notices a breach (a diff
or full where the new rift is greater than the old one).
Because this is an issue on the live network, I wrote state adapters
for Gall and Clay. The Gall one just removes the rift from our state,
but the Clay one is much more involved because we have to upgrade
instances of the clad monad that are possibly in progress.
Specifically, since more input is possible than before, we must wrap any
in-progress instances of the monad in a function that handles the
potential new input from Jael. This temporarily preservers a copy of
the old kernel, but only until the current commit/merge/update has
completed.
The real solution for Clay is to factor out those IO-heavy instances to
userspace tapp/async/imp/threads, and if an upgrade happens in the
middle, you should simply restart them.
Fixes#1852
Vere will attempt to download a pill from https://bootstrap.urbit.org if
not given one explicitly. These pill filenames have traditionally had
the format:
urbit-$URBIT_VERSION.pill
but this is inconsistent with the manner in which versions are referred
to elsewhere. For example, release binaries are packaged in tarballs
with the names:
urbit-linux64-v$URBIT_VERSION.tgz
urbit-darwin-v$URBIT_VERSION.tgz
Note the 'v' prepended to URBIT_VERSION.
From v0.9.2 forward it is expected that bootstrap pills will also use
the 'v' prefix, i.e.
urbit-v$URBIT_VERSION.pill
so this commit makes the appropriate change in the daemon.

are not equal. This commit merely rights that wrong.
