We need to manually convert to string, as the default ToDynamic
impl encodes the underlying bits value from the bitfield and
that doesn't round trip with the try_from String impl
Brief usage notes here:
```lua
local wezterm = require 'wezterm'
local a_plugin = wezterm.plugin.require "https://github.com/owner/repo"
local config = wezterm.config_builder()
a_plugin.apply_to_config(config)
return config
```
The referenced repo is expected to have a `plugin/init.lua` file,
and by convention, return a module that exports an `apply_to_config`
function that accepts at least a config builder parameter, but may
pass other parameters, or a lua table with a `config` field that maps
to a config build parameter.
`wezterm.plugin.require` will clone the repo if it doesn't already
exist and store it in the runtime dir under `plugins/NAME` where
`NAME` is derived from the repo URL. Once cloned, the repo is
NOT automatically updated.
Only HTTP (or local filesystem) repos are allowed for the git URL;
we cannot currently use ssh for this due to conflicting version
requirements that I'll take a look at later.
`wezterm.plugin.require` will then perform `require "NAME"`,
and since the default `package.path` now includes the appropriate
location from the runtime dir, the module should load.
Two other functions are available:
`wezterm.plugin.list()` will list the plugin repos.
`wezterm.plugin.update_all()` will attempt to fast-forward or `pull
--rebase` each of the repos it finds. It doesn't currently do anything
proactive to reload the configuration afterwards; the user will need to
do that themselves.
Rust 1.67, released today, is a bit more particular about the layout
of the memory used in TeenyString and segfaults in the test suite.
On closer inspection, our Drop impl was casting to Vec<u8> instead of
TeenyStringHeap and the fault was freeing bogus memory within that
region.
Fixing the cast to the correct type resolves the issue.
The motivation here was to remove some similar but not quite the same
logic that existed for starting up when using `wezterm connect`.
Now `wezterm connect DOMAIN` is implemented as `wezterm start --domain
DOMAIN --attach --always-new-process` and a little extra hand-wave to
ensure that the default domain is set correctly.
The startup events have been refactored a bit; a new gui-attached
event is emitted after attaching and starting any default programs
in the selected domain at startup.
That event can be used to maximize windows and so on, if desired.
The gui-attached event is independent of the startup command and fires
for `wezterm connect`, which `gui-startup` did not (and could not) do.
base arch linux installation doesn't include `hostname` binary as it's part of
a separate `inetutils` package, use systemd `hostnamectl` which is available in
all systemd-based distributions
config_builder helps to make issues more visible/useful in the case
where you may have typod a config option, or otherwise assigned
an incorrect value.
The tcgetpgrp call appears to have high variance in latency, ranging
from 200-700us on my system.
If you have 10 tabs and mouse over the tab bar, that's around 7ms
spent per frame just figuring out the foreground process; that doesn't
include actually extracting the process executable or current working
directory paths.
This was exacerbated by the mouse move events triggering a tab bar
recompute on every pixel of mouse movement.
This commit takes the following steps to resolve this:
* We now only re-compute the tab bar when the UI item is changed by
a mouse movement
* A simple single-item cache is now used on unix that allows the caller
to proceed quickly with stale-but-probably-still-mostly-accurate data
while queuing up an update to a background thread which can absorb
the latency.
The result of this is that hovering over several tabs in quick
succession no longer takes a noticeable length of time to render the
hover, but the consequence is that the contents of a given tab may be
stale by 300-400ms.
I think that trade-off is worth while.
We already have a similar trade-off on Windows, although we don't
yet do the updates in a different thread on Windows. Perhaps in
a follow up commit?
