Support for Wasm modules.
Note this implements the standard where the default export is the
instance (not the module). The module will come later with source phase
imports.
```ts
import { add } from "./math.wasm";
console.log(add(1, 2));
```
```
> deno compile --allow-read=. --include data-file.txt main.js
```
This only applies to files on the filesystem. For remote modules, that's
going to have to wait for `import ... from "./data.txt" with { "type":
"bytes" }` or whatever it will be.
The issue was this package had an import like: `".//index.js"` and we
resolved that as specified, but node normalizes it to `"./index.js"` so
we have to copy node.
This commit adds support for "dependencies" in `deno task` subcommand:
```jsonc
{
"tasks": {
"build": "deno run -RW build.ts",
"generate": "deno run -RW generate.ts",
"serve": {
"command": "deno run -RN server.ts",
"dependencies": ["build", "generate"]
}
}
}
```
Executing `deno task serve` will first execute `build` and `generate`
tasks (in parallel) and once both complete the `serve` task will be executed.
Number of tasks run in parallel is equal to the no of cores on the
machine, and respects `DENO_JOBS` env var if one is specified.

This PR removes the public Deno.tracing.Span API.
We are not confident we can ship an API that is
better than the `@opentelemetry/api` API, because
V8 CPED does not support us using `using` to
manage span context. If this changes, we can
revisit this decision. For now, users wanting
custom spans can instrument their code using
the `@opentelemetry/api` API and `@deno/otel`.
This PR also speeds up the OTEL trace generation
by a 30% by using Uint8Array instead of
strings for the trace ID and span ID.
Adds a lazily created code cache to `deno compile` by default.
The code cache is created on first run to a single file in the temp
directory and is only written once. After it's been written, the code
cache becomes read only on subsequent runs. Only the modules loaded
during startup are cached (dynamic imports are not code cached).
The code cache can be disabled by compiling with `--no-code-cache`.
Closes #26425
## Overview
This PR adds support for specifying multiple environment files as
arguments when using the Deno CLI. Subsequent files override
pre-existing variables defined in previous files.
If the same variable is defined in the environment and in the file, the
value from the environment takes precedence.
## Example Usage
```bash
deno run --allow-env --env-file --env-file=".env.one" --env-file=".env.two" script.ts
```

This commit adds `Deno.jupyter.image` API to display PNG and JPG images:
```
const data = Deno.readFileSync("./my-image.jpg");
Deno.jupyter.image(data);
Deno.jupyter.image("./my-image.jpg");
```
This commit changes three aspects of `deno task`:
1. Tasks can now be written using object notation like so:
```jsonc
{
"tasks": {
"foo": "deno run foo.js",
"bar": {
"command": "deno run bar.js"
}
}
```
2. Support for comments for tasks is now removed. Comments above tasks
will
no longer be printed when running `deno task`.
3. Tasks written using object notation can have "description" field that
replaces
support for comments above tasks:
```jsonc
{
"tasks": {
"bar": {
"description": "This is a bar task"
"command": "deno run bar.js"
}
}
```
```
$ deno task
Available tasks:
- bar
// This is a bar task
deno run bar.js
```
Pulled most of the changes from
https://github.com/denoland/deno/pull/26467 to
support "dependencies" in tasks. Additionally some cleanup was performed
to make code easier to read.

Improving the breadth of collected data, and ensuring that the collected
data is more likely to be successfully reported.
- Use `log` crate in more places
- Hook up `log` crate to otel
- Switch to process-wide otel processors
- Handle places that use `process::exit`
Also adds a more robust testing framework, with a deterministic tracing
setting.

This commit makes comments in code snippets in JSDoc or markdown
preserved when they are executed as tests. In particular, this is needed
to get TypeScript special comments such as `@ts-ignore` or
`@ts-expect-error` to work correctly.
Fixes #26728
This will respect `"type": "commonjs"` in a package.json to determine if
`.js`/`.jsx`/`.ts`/.tsx` files are CJS or ESM. If the file is found to
be ESM it will be loaded as ESM though.
Initial import of OTEL code supporting tracing. Metrics soon to come.
Implements APIs for https://jsr.io/@deno/otel so that code using
OpenTelemetry.js just works tm.
There is still a lot of work to do with configuration and adding
built-in tracing to core APIs, which will come in followup PRs.

Fixes #26677
Some packages (like supabase) declare bin entries that don't exist until
lifecycle scripts are run. For instance, the lifecycle script downloads
a binary file which serves as a bin entrypoint.
Unfortunately you can't just defer setting up the bin entries until
after lifecycle scripts have run, because the scripts may rely on them.
I looked into this, and PNPM just re-links bin entries after running
lifecycle scripts. I think that's about the best we can do as well.
Note that we'll only re-setup bin entries for packages whose lifecycle
scripts we run. This should limit the performance cost, as typically a
given project will not have many lifecycle scripts (and of those, many
of them probably don't have bin entries to set up).

`performance.timeOrigin` was being set from when JS started executing,
but `op_now` measures from an `std::time::Instant` stored in `OpState`,
which is created at a completely different time. This caused
`performance.timeOrigin` to be very incorrect. This PR corrects the
origin and also cleans up some of the timer code.
Compared to `Date.now()`, `performance`'s time origin is now
consistently within 5us (0.005ms) of system time.

Fixes #26116.
Handle the new error and treat is as lacking permission to make
symlinks, but also to make this more robust, just always fall back to
junctions no matter what the actual error is. Instead, warn if the error
isn't one we've handled, but go on to attempt creating the junction
This commit adds support for wildcard packages in `workspace`
configuration option in `deno.json`. This is now supported:
```
{
"workspace": [
"./packages/*"
]
}
```
Closes https://github.com/denoland/deno/issues/25783
* cts support
* better cjs/cts type checking
* deno compile cjs/cts support
* More efficient detect cjs (going towards stabilization)
* Determination of whether .js, .ts, .jsx, or .tsx is cjs or esm is only
done after loading
* Support `import x = require(...);`

Fixes #25342.
Still not sure on the exact user agent to set (should it include
`node`?).
After this PR, here's the state of running some `create-*` packages
(just ones I could think of off the top of my head):
| package | prints/runs/suggests deno install | notes |
| ---------------- | ------------- | ------ |
| `create-next-app` | ❌ | falls back to npm, needs a PR
([code](c32e280209/packages/create-next-app/helpers/get-pkg-manager.ts (L3)))
| `sv create` | ❌ | uses `package-manager-detector`, needs a PR
([code](https://github.com/antfu-collective/package-manager-detector/tree/main))
| `create-qwik` | ✅ | runs `deno install` but suggests `deno start`
which doesn't work (should be `deno task start` or `deno run start`)
| `create-astro` | ✅ | runs `deno install` but suggests `npm run dev`
later in output, probably needs a PR
| `nuxi init` | ❌ | deno not an option in dialog, needs a PR
([code](f04e2e8944/src/commands/init.ts (L96-L102)))
| `create-react-app` | ❌ | uses npm
| `ng new` (`@angular/cli`) | ❌ | uses npm
| `create-vite` | ✅ | suggests working deno commands 🎉
| `create-solid` | ❌ | suggests npm commands, needs PR
It's possible that fixing `package-manager-detector` or other packages
might make some of these just work, but haven't looked too carefully at
each
This PR addresses issue #25600
Changes:
Updated `fn has_hmr` to check `serve` subcommand and return its hmr
value if found, in order to run the worker in serve mode with
hmr_runner. Thus the hmr event can be dispatched upon changes on the
file served.
Fixes percent encodings showing up when installing scoped packages via
`deno add` or `deno install`. The issue is caused by us trying to map
back the package name from the resolved http url. This doesn't and has
never worked with private registries. The proper solution would be to
pass the original specifier into here, but that's a bit of a bigger
refactor.
So for now the quickest workaround is to replace `%2f` back to `/`.
Fixes https://github.com/denoland/deno/issues/26576
Spend some time stepping through the npm client code and noticed that
the bearer token was different from ours. They do some double encoding
and @dsherret helped me in matching the encoding behavior.

The --watch option should clear the screen scrollback buffer as well as
the screen itself.
On Ubuntu (22.04 Jammy) the 'clear' command generates
"\x1B[H\x1B[2J\x1B[3J"; that is:
- \E[H - cursor home
- \E[2J - clear entire screen
- \E[3J - clear entire screen & scrollback buffer.
By contrast, Deno defined CLEAR_SCREEN as "\x1B[2J\x1B[1;1H", which
fails to clear the scrollback buffer.
The "\E[H\E[2J\E[3J" sequence works on MacOS (Sonoma) (using printf);
I'm not able to test on Windows.

Ended up being a `deno_graph` bug causing the error to surface. This PR
updates `deno_graph` to pick up the fix and reverts the temporary
workaround that skipped JSON exports.
Fixes #26498.
This was a sort of intentional decision originally, as I wanted to avoid
caching extra files that may not be needed. It seems like that behavior
is unintuitive, so I propose we cache all of the exports of listed jsr
packages when you run a bare `deno install`.
This commit makes sure that `deno add`, `deno install` and `deno remove`
update the lockfile if only `package.json` file is present.
Fixes https://github.com/denoland/deno/issues/26270
1. Respects the formatting of the file (ex. keeps four space indents or
tabs).
2. Handles editing of comments.
3. Handles trailing commas.
4. Code is easier to maintain.
This PR fixes the issue where mapped specifiers in a workspace member
would never be found. Only mapped paths from the workspace root would
resolve.
This was caused by always passing the workspace root url to the import
map resolver instead of the workspace member one.

I don't have a reliable reproduction for it, but it makes it
painful to use the Jupyter kernel with semi-frequent random panics.
The completions don't always work correctly anyway, so I think
it's better to just not panic here for the time being.
