As pointed out in https://github.com/denoland/deno/issues/21067 , it's
confusing that `deno doc --lint mod.ts` outputs the documentation to
stdout on success. Instead, it would be better if it outputted how many
files were checked similar to what `deno lint` does on success. It still
outputs the documentation if `--lint` or `--html` are provided so this
is non-breaking.
This commit adds granular `--unstable-*` flags:
- "--unstable-broadcast-channel"
- "--unstable-ffi"
- "--unstable-fs"
- "--unstable-http"
- "--unstable-kv"
- "--unstable-net"
- "--unstable-worker-options"
- "--unstable-cron"
These flags are meant to replace a "catch-all" flag - "--unstable", that
gives a binary control whether unstable features are enabled or not. The
downside of this flag that allowing eg. Deno KV API also enables the FFI
API (though the latter is still gated with a permission).
These flags can also be specified in `deno.json` file under `unstable`
key.
Currently, "--unstable" flag works the same way - I will open a follow
up PR that will print a warning when using "--unstable" and suggest to use
concrete "--unstable-*" flag instead. We plan to phase out "--unstable"
completely in Deno 2.
Implements `WebSocket` over http/2. This requires a conformant http/2
server supporting the extended connect protocol.
Passes approximately 100 new WPT tests (mostly `?wpt_flags=h2` versions
of existing websockets APIs).
This is implemented as a fallback when http/1.1 fails, so a server that
supports both h1 and h2 WebSockets will still end up on the http/1.1
upgrade path.
The patch also cleas up the websockets handshake to split it up into
http, https+http1 and https+http2, making it a little less intertwined.
This uncovered a likely bug in the WPT test server:
https://github.com/web-platform-tests/wpt/issues/42896
This change adds the `--env=[FILE]` flag to the `run`, `compile`,
`eval`, `install` and `repl` subcommands. Environment variables set in
the CLI overwrite those defined in the `.env` file.
Adds a new `--lint` flag to `deno doc` that surfaces three kinds of
diagnostics:
1. Diagnostic for non-exported type referenced in an exported type.
* Why? People often forget to export types from a module in TypeScript.
To supress this diagnostic, add an `@internal` jsdoc tag to the internal
type.
1. Diagnostic for missing return type or missing property type on a
**public** type.
* Why? Otherwise `deno doc` will not display good documentation. Adding
explicit types also helps with type checking performance.
1. Diagnostic for missing jsdoc on a **public** type.
* Why? Everything should be documented. This diagnostic can be supressed
by adding a jsdoc comment description.
If the lint passes, `deno doc` generates documentation as usual.
For example, checking for deno doc diagnostics on the CI:
```shellsession
$ deno doc --lint mod.ts second_entrypoint.ts > /dev/null
```
This feature is incredibly useful for library authors.
## Why not include this in `deno lint`?
1. The command needs the documenation output in order to figure out the
diagnostics.
1. `deno lint` doesn't understand where the entrypoints are. That's
critical for the diagnostics to be useful.
1. It's much more performant to do this while generating documentation.
1. There is precedence in rustdoc (ex. `#![warn(missing_docs)]`).
## Why not `--check`?
It is confusing with `deno run --check`, since that means to run type
checking (and confusing with `deno check --docs`).
## Output Future Improvement
The output is not ideal atm, but it's fine for a first pass. We will
improve it in the future.

Use new https://github.com/denoland/rustls-tokio-stream project instead
of tokio-rustls for direct websocket connections. This library was
written from the ground up to be more reliable and should help with
various bugs that may occur due to underlying bugs in the old library.
Believed to fix #20355, #18977, #20948
This commit adds support for multiple entry points to `deno doc`.
Unfortunately to achieve that, I had to change the semantics of the
command to explicitly require `--filter` parameter for filtering
symbols, instead of treating second free argument as the filter argument.
`deno doc --builtin` is still supported, but cannot be mixed with
actual entrypoints.
Upgrades to deno_doc 0.70 which includes the feature for showing
non-exported types referenced in exported types as well as a much more
advanced deno doc that uses a symbol graph.
This PR adds a new unstable "bring your own node_modules" (BYONM)
functionality currently behind a `--unstable-byonm` flag (`"unstable":
["byonm"]` in a deno.json).
This enables users to run a separate install command (ex. `npm install`,
`pnpm install`) then run `deno run main.ts` and Deno will respect the
layout of the node_modules directory as setup by the separate install
command. It also works with npm/yarn/pnpm workspaces.
For this PR, the behaviour is opted into by specifying
`--unstable-byonm`/`"unstable": ["byonm"]`, but in the future we may
make this the default behaviour as outlined in
https://github.com/denoland/deno/issues/18967#issuecomment-1761248941
This is an extremely rough initial implementation. Errors are
terrible in this and the LSP requires frequent restarts. Improvements
will be done in follow up PRs.
This brings in [`display`](https://github.com/rgbkrk/display.js) as part
of the `Deno.jupyter` namespace.
Additionally these APIs were added:
- "Deno.jupyter.md"
- "Deno.jupyter.html"
- "Deno.jupyter.svg"
- "Deno.jupyter.format"
These APIs greatly extend capabilities of rendering output in Jupyter
notebooks.

This fixes #20767.
We were losing `this` and then when an exception was happening, it
didn't show up in the output because we weren't bubbling up exceptions
from within a user defined function for displaying. I thought about
doing a `.call(object)` but didn't want to get in the way of a bound
`this` that a user or library was already putting on the function.
Adds `buffers` to the `Deno.jupyter.broadcast` API to send binary data
via comms. This affords the ability to send binary data via websockets
to the jupyter widget frontend.
Adds an experimental unstable built-in package manager to Deno, but it is
currently not usable because the registry infrastructure hasn't been
setup and it points to a non-existent url by default. The default
registry url can be configured via the `DENO_REGISTRY_URL` environment
variable.
This commit improves async op sanitizer speed by only delaying metrics
collection if there are pending ops. This
results in a speedup of around 30% for small CPU bound unit tests.
It performs this check and possible delay on every collection now,
fixing an issue with parent test leaks into steps.
This commit adds "deno jupyter" subcommand which
provides a Deno kernel for Jupyter notebooks.
The implementation is mostly based on Deno's REPL and
reuses large parts of it (though there's some clean up that
needs to happen in follow up PRs). Not all functionality of
Jupyter kernel is implemented and some message type
are still not implemented (eg. "inspect_request") but
the kernel is fully working and provides all the capatibilities
that the Deno REPL has; including TypeScript transpilation
and npm packages support.

This adds the ability to pattern match unordered lines. For example, the
downloading messages may appear in any order
```
[UNORDERED_START]
Download https://localhost:4546/a.ts
Download https://localhost:4546/b.ts
[UNORDERED_END]
Hello!
```
Additionally, I've made the pattern matching slightly more strict and the output better.
Closes #14122.
Adds two extensions to `--allow-run` behaviour:
- When `--allow-run=foo` is specified and `foo` is found in the `PATH`
at startup, `RunDescriptor::Path(which("foo"))` is added to the
allowlist alongside `RunDescriptor::Name("foo")`. Currently only the
latter is.
- When run permission for `foo` is queried and `foo` is found in the
`PATH` at runtime, either `RunDescriptor::Path(which("foo"))` or
`RunDescriptor::Name("foo")` would qualify in the allowlist. Currently
only the latter does.
Disables `BenchContext::start()` and `BenchContext::end()` for low
precision benchmarks (less than 0.01s per iteration). Prints a warning
when they are used in such benchmarks, suggesting to remove them.
```ts
Deno.bench("noop", { group: "noops" }, () => {});
Deno.bench("noop with start/end", { group: "noops" }, (b) => {
b.start();
b.end();
});

This PR adds a test reporter for the [Test Anything
Protocol](https://testanything.org).
It makes the following implementation decisions:
- No TODO pragma, as there is no such marker in `Deno.test`
- SKIP pragma for `ignore`d tests
- Test steps are treated as TAP14 subtests
- Support for this in consumers seems spotty
- Some consumers will incorrectly interpret these markers, resulting in
unexpected output
- Considering the lack of support, and to avoid implementation
complexity,
subtests are at most one level deep (all test steps are in the same
subtest)
- To accommodate consumers that use comments to indicate test-suites
(unspecced)
- The test module path is output as a comment
- This is disabled for `--parallel` testing
- Failure diagnostics are output as JSON, which is also valid YAML
- The structure is not specified, so the format roughly follows the spec
example:
```
---
message: "Failed with error 'hostname peebles.example.com not found'"
severity: fail
found:
hostname: 'peebles.example.com'
address: ~
wanted:
