This commit adds "deno add" subcommand that has a basic support for
adding "jsr:" packages to "deno.json" file.
This currently doesn't support "npm:" specifiers and specifying version
constraints.
This initially uses the new diagnostic printer in `deno lint`,
`deno doc` and `deno publish`. In the limit we should also update
`deno check` to use this printer.
This commit deprecates "--unstable" flag.
When "--unstable" flag is encountered a warning like this is printed:
```
The `--unstable` flag is deprecated, use granular `--unstable-*` flags instead.
Learn more at: https://docs.deno.com/runtime/manual/tools/unstable_flags
```
When "--unstable" flag is used and an unstable API is called an
additional warning like this is printed for each API call:
```
The `Deno.dlopen` API was used with `--unstable` flag. The `--unstable` flag is deprecated, use granular `--unstable-ffi` instead.
Learn more at: https://docs.deno.com/runtime/manual/tools/unstable_flags
```
When no "--unstable-*" flag is provided and an unstable API is called
following
warning is issued before exiting:
```
Unstable API 'Deno.dlopen'. The `--unstable-ffi` flag must be provided.
```

This commit adds support for [Stage 3 Temporal API
proposal](https://tc39.es/proposal-temporal/docs/).
The API is available when `--unstable-temporal` flag is passed.

This commit removes conditional type-checking of unstable APIs.
Before this commit `deno check` (or any other type-checking command and
the LSP) would error out if there was an unstable API in the code, but not
`--unstable` flag provided.
This situation hinders DX and makes it harder to configure Deno. Failing
during runtime unless `--unstable` flag is provided is enough in this case.
The self-upgrade feature is undesirable when deno is installed from
(Linux) distribution repository - using a system package manager. This
change will allow package maintainers to build deno with the "upgrade"
subcommand and background check disabled.
When the user runs `deno upgrade <args>` and the upgrade feature is
disabled, it will exit with error message explaining that this deno
binary was built without the upgrade feature.
Note: This patch is already used in the Alpine Linux’s
[deno](https://pkgs.alpinelinux.org/packages?name=deno) package.
This commit moves all Chrome Devtools Protocol messages to `cli/cdp.rs`
and refactors all places using these types to pull them from a common
place.
No functional changes.
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.
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 commit adds ability to print metrics of the Tokio
runtime to the console by passing "DENO_TOKIO_METRICS=1"
env var.
Metrics will be printed every second, but this can be changed
by "DENO_TOKIO_METRICS_INTERVAL=500" env var.
This reverts commit 798c1ad0f1.
Reverting because this change caused a spike in memory usage, but we
can't fully realise gains from lower GC pressure from more optimal
malloc/ free provided by "jemalloc".
We might revisit the topic in future.
Partially supersedes #19016.
This migrates `spawn` and `spawn_blocking` to `deno_core`, and removes
the requirement for `spawn` tasks to be `Send` given our single-threaded
executor.
While we don't need to technically do anything w/`spawn_blocking`, this
allows us to have a single `JoinHandle` type that works for both cases,
and allows us to more easily experiment with alternative
`spawn_blocking` implementations that do not require tokio (ie: rayon).

This is the initial support for npm and node specifiers in `deno
compile`. The npm packages are included in the binary and read from it via
a virtual file system. This also supports the `--node-modules-dir` flag,
dependencies specified in a package.json, and npm binary commands (ex.
`deno compile --unstable npm:cowsay`)
Closes #16632
This removes `ProcState` and replaces it with a new `CliFactory` which
initializes our "service structs" on demand. This isn't a performance
improvement at the moment for `deno run`, but might unlock performance
improvements in the future.
1. Adds cli/standalone folder
2. Writes the bytes directly to the output file. When adding npm
packages this might get quite large, so let's not keep the final output
in memory just in case.
1. Breaks up functionality within `ProcState` into several other structs
to break out the responsibilities (`ProcState` is only a data struct
now).
2. Moves towards being able to inject dependencies more easily and have
functionality only require what it needs.
3. Exposes `Arc<T>` around the "service structs" instead of it being
embedded within them. The idea behind embedding them was to reduce the
verbosity of needing to pass around `Arc<...>`, but I don't think it was
exactly working and as we move more of these structs to be more
injectable I don't think the extra verbosity will be a big deal.
Removes the functions in the `emit` module and replaces them with an
`Emitter` struct that can have "ctor dependencies" injected rather than
using functions to pass along the dependencies.
This is part of a long term refactor to move more functionality out of
proc state.
- Generalizes the npm version code (ex. `NpmVersion` -> `Version`,
`NpmVersionReq` -> `VersionReq`). This is a slow refactor towards
extracting out this code for deno specifiers and better usage in
deno_graph.
- Removes `SpecifierVersionReq`. Consolidates `NpmVersionReq` and
`SpecifierVersionReq` to just `VersionReq`
- Removes `NpmVersionMatcher`. This now just looks at `VersionReq`.
- Paves the way to allow us to create `NpmPackageReference`'s from a
package.json's dependencies/dev dependencies
(`VersionReq::parse_from_npm`).
