We unified most code paths earlier, but the common code will still
import Main locally if no extension manager was injected before.
Now that the old extensionUtils was split between extension and
preferences, each of those modules can simply import the manager
from its corresponding environment, and then inject it into the
shared module.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2837>
For the time being this mostly means re-exporting functions
from the shared module. However openPrefs() is now only
available to extensions, and we stop exporting both
getCurrentExtension() and setExtensionManager() to either
extensions or prefs.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2837>
We got rid of all uses of extension utils code in the gnome-shell
process itself, and everything that is now using it - including
extensions - is already loaded as module.
We can therefore quickly move the file to ESM, which will help
a bit with upcoming changes.

ExtensionUtils was originally used for shared functions between
the extension system and the (old) prefs-tool, but then gained
useful API meant for extensions themselves.
It's a bit weird to mix the two, so split out the extension convenience
API into a separate module.
We will soon split up the module further, and add specific "flavors"
for extensions and preferences, with the current code providing a
shared base for both.
That should explain both the new location and the odd module name. :-)

Now that we always have an extension manager object, we can use
the same code path for use from extensions and prefs.
For that, inject the D-Bus service's extensionManager instead
of the current extension.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2832>
ExtensionUtils' getCurrentExtension() method currently either
returns the extension that was injected with setCurrentExtension(),
or imports Main locally to access the extensionManager.
But local imports won't work anymore when we convert to ESM,
and setCurrentExtension() is only an option for prefs.
Instead of diverging the code paths even further, we'll unify
the two cases as much as possible.
As a first step, add a basic extension manager in the Extensions
D-Bus service that exposes the same lookup() API as the "real"
extension manager.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2832>
When looking for a directory name that matches the extension UUID,
we can just as well use GLib's dirname()/basename() functions
instead of wrapping the path in a GFile.
We also know that the original path corresponds to a regular file
and not a directory, so rearrange the loop to avoid a lookup that
is guaranteed to fail.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2832>
We currently use a regular expression to extract the exact file path
from a stack line. That RE is no longer accurate:
- we assume a line number at the end, but at one point the column
number was added as well
- stacks from ES modules use file:// URIs instead of plain paths
Luckily that doesn't matter: We don't want to access any actual
files, so all we need is a path that can be traversed and that
contains the UUID.
We can get that with simple string manipulation, so avoid the regex
overhead.

gi modules are always loaded (there is no API for "set version without
loading"), so
we need to break dependencies.js into three sections:
- Required
- Compile-time optional
- Runtime optional
Required dependencies are always imported, compile-time optional
dependencies
are loaded if gnome-shell is compiled with support for them, and for
runtime optional dependencies we catch any errors when attempting to
load them.
If runtime optional dependencies fail to load we log a debug-level
message.

Removes the init() function in favor of executing all environment
changes when the file is imported.
Additionally ports all unit tests using imports.gi.environment.init() to
use the updated module.

We started to version them last cycle, so docs can be differentiated
between versions. It is not *expected* that two versions show up
on the same system, but then it also doesn't hurt handling it.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2822>
Once environment.js is an ES module we need to ensure we can dynamically
specify the version for required GI dependencies such as Clutter.
Moving dependency version setup to dependencies.js ensures gi.require
calls are done before environment.js imports any utilities.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2822>
The environment module is used to initialize the environment, yet it
currently also defines the adjustAnimationTime() function.
Ideally it should not export any utility functions, in particular
once converted to ESM.
The function cannot be moved to the existing Utils module, as that
depends on an initialized environment, and can therefore not be
imported from environment.js, so use that opportunity to group
together several animation helpers in a new animationUtils module.

This allows using await in the command (or the header we
add to it), for example when handling Promises or importing
a module dynamically.
The latter will be crucial when porting to ESM.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2842>
Part of the possible completions involves evaluating the part
of the passed in text that looks like an object, so that we
can query it for properties.
Using a Function or eval() for that means that we can only
complete text that does not use `await`. To get over that
limitation, evaluate the text in an AsyncFunction instead.

We currently throw an error when encountering a result that cannot
be represented as string, with the prompt appearing somewhat stuck
(the input cannot be committed).
Showing a lame fallback instead at least avoids that issue. When
the object has a typeof 'object' but is not an instanceof Object,
we are likely dealing with an ES module, and can show a slightly
less lame fallback.

console.log() is implemented with structured logging, and as we
set an appropriate log domain, it's identical to the custom function
bar the custom fields with extension data.
Few people know about those custom fields, and adding them comes
at a cost, as we end up producing and parsing a stacktrace on
every log() call.
It therefore seems appropriate to drop the custom function, and
turn the global log() symbol into a simple convenience alias for
console.log().
If it turns out that people do miss the custom fields, we can add
an alternative to ExtensionUtils.

`toLocaleFormat` is now `formatDateWithCFormatString` and formatTime and
formatTimeSpan are moved into dateUtils.
Instead of overriding system.clearDateCaches, add a helper in dateUtils.

Now that scripts are loaded as external modules, there's no reason
anymore for bundling them with the gnome-shell executable. Just
move the scripts into a dedicated folder in tests/ and run them
from there.

Environment variables aren't the best option to pass parameters
to a process (wouldn't it be "fun" if SHELL_PERF_MODULE appeared
in a regular user session?).
Instead, use a (hidden) --automation-script command line flag to
specify a script file that should be used to drive an automated
session.
As a side effect, the script no longer has to be relative to the
main module itself, so it will be possible to run scripts that
aren't bundled with the shell sources.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2812>
The perf scripts that can be used to script the gnome-shell UI
for testing are sufficiently separate from the rest of the code
base to allow porting them to ESM modules before the rest of
the code base.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2812>
The file indicates to the systemd shutdown scripts that extensions
should be disabled, so that extensions that crash the shell on
startup cannot lock out the user indefinitely.
For that purpose, we create the file before initializing extensions,
and remove it after 60 seconds. That generally works, because it's
highly unlikely that a session genuinely ends within the first minute.
It's possible though (for example during developments or when running
tests), so also remove the file when shutting down cleanly before
the timeout.

Now that extensions themselves are imported as modules, do the
same for their preference dialogs.
Extensions must now export a class with a `fillPreferencesWindow()`
method as default.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2795>
Continue the move to ESM by loading modules dynamically with
the standard import() expression, rather than by installing a
custom (legacy) importer.
This is a breaking change that affects all extensions, as they
now need to explicitly export the expected symbols.
As we are already breaking all extensions, take that opportunity
and remove support for the individual entry points: Using a
class with enable()/disable() methods has been the recommended
pattern for a long time, it is now the only entry point.
Instead of instantiating the class from an `init()` function,
the class must now be exported as default to be recognized.
Additionally, we no longer install an importer on the extension
object, so extensions that consist of more than one file MUST
import those files as modules now.
There will be a second breaking change for extensions when
gnome-shell's own code is ported to ESM, so most extension
developers will likely want to wait until the port is complete
before starting to port their extensions.
Based on a commit from Evan Welsh.

We want to replace gjs' custom (and now legacy) imports system
with standard EcmaScript modules: JS developers are already
familiar with them, they have better tooling support and using
standard features over non-standard ones is generally the right
thing to do.
Our D-Bus services are separate from the main process, and thus
can be ported separately (except for the few imports that are
shared with the main process' code base).
