This change removes the handling of `--check` and `--no-check` flags from
`deno repl` subcommand.
Currently these flags don't have effects, and the help output for these
options are incorrect and confusing.
closes #26042
When using the `--unstable-detect-cjs` flag or adding `"unstable":
["detect-cjs"]` to a deno.json, it will make a JS file CJS if the
closest package.json contains `"type": "commonjs"` and the file is not
an ESM module (no TLA, no `import.meta`, no `import`/`export`).
The exploit `--allow-import` is preventing against requires a
compromised host. To make things easier and given its popularity, we're
going to have the default `--allow-import` value include
`cdn.jsdelivr.net:443`, but this can be overridden by replacing the
`--allow-import` value with something else.
Currently we only warn once. With this PR, we continue to warn about
not-run scripts on explicit `deno install` (or cache). For `run` (or
other subcommands) we only warn the once, as we do currently.
This replaces `--allow-net` for import permissions and makes the
security sandbox stricter by also checking permissions for statically
analyzable imports.
By default, this has a value of
`--allow-import=deno.land:443,jsr.io:443,esm.sh:443,raw.githubusercontent.com:443,gist.githubusercontent.com:443`,
but that can be overridden by providing a different set of hosts.
Additionally, when no value is provided, import permissions are inferred
from the CLI arguments so the following works because
`fresh.deno.dev:443` will be added to the list of allowed imports:
```ts
deno run -A -r https://fresh.deno.dev
```

Refactors the lifecycle scripts code to extract out the common
functionality and then uses that to provide a warning in the global
resolver.
While ideally we would still support them with the global cache, for now
a warning is at least better than the status quo (where people are
unaware why their packages aren't working).
This commits stabilizes CSS, HTML and YAML formatters
in `deno fmt`.
It is no longer required to use either of these flags:
- `--unstable-css`
- `--unstable-html`
- `--unstable-yaml`
Or these `unstable` options in the config file:
- `fmt-css`
- `fmt-html`
- `html-yaml`
Fixes a regression where we were ignoring `--node-modules-dir` if there
was no value passed with it. We should instead default to "auto", to
maintain compat with deno 1
This commit lets `deno test --doc` command actually evaluate code snippets in
JSDoc and markdown files.
## How it works
1. Extract code snippets from JSDoc or code fences
2. Convert them into pseudo files by wrapping them in `Deno.test(...)`
3. Register the pseudo files as in-memory files
4. Run type-check and evaluation
We apply some magic at the step 2 - let's say we have the following file named
`mod.ts` as an input:
````ts
/**
* ```ts
* import { assertEquals } from "jsr:@std/assert/equals";
*
* assertEquals(add(1, 2), 3);
* ```
*/
export function add(a: number, b: number) {
return a + b;
}
````
This is virtually transformed into:
```ts
import { assertEquals } from "jsr:@std/assert/equals";
import { add } from "files:///path/to/mod.ts";
Deno.test("mod.ts$2-7.ts", async () => {
assertEquals(add(1, 2), 3);
});
```
Note that a new import statement is inserted here to make `add` function
available. In a nutshell, all items exported from `mod.ts` become available in
the generated pseudo file with this automatic import insertion.
The intention behind this design is that, from library user's standpoint, it
should be very obvious that this `add` function is what this example code is
attached to. Also, if there is an explicit import statement like
`import { add } from "./mod.ts"`, this import path `./mod.ts` is not helpful for
doc readers because they will need to import it in a different way.
The automatic import insertion has some edge cases, in particular where there is
a local variable in a snippet with the same name as one of the exported items.
This case is addressed by employing swc's scope analysis (see test cases for
more details).
## "type-checking only" mode stays around
This change will likely impact a lot of existing doc tests in the ecosystem
because some doc tests rely on the fact that they are not evaluated - some cause
side effects if executed, some throw errors at runtime although they do pass the
type check, etc. To help those tests gradually transition to the ones runnable
with the new `deno test --doc`, we will keep providing the ability to run
type-checking only via `deno check --doc`. Additionally there is a `--doc-only`
option added to the `check` subcommand too, which is useful when you want to
type-check on code snippets in markdown files, as normal `deno check` command
doesn't accept markdown.

Closes #4716
`--allow-run` even with an allow list has essentially been
`--allow-all`... this locks it down more.
1. Resolves allow list for `--allow-run=` on startup to an absolute
path, then uses these paths when evaluating if a command can execute.
Also, adds these paths to `--deny-write`
1. Resolves the environment (cwd and env vars) before evaluating
permissions and before executing a command. Then uses this environment
to evaluate the permissions and then evaluate the command.
Remove `--allow-hrtime` and `--deny-hrtime`. We are doing this because
it is already possible to get access to high resolution timers through
workers and SharedArrayBuffer.

This commit hides following unstable flags:
- `--unstable-ffi` (the API is now stable)
- `--unstable-webgpu` (this API is now stable)
- `--unstable-fs` (no more unstable APIs)
- `--unstable-byonm` (BYONM is on by default)
The flags are still parseable, but they are not used. Concrete cleanup
will be done in a follow up PR.
`deno bundle` now produces:
```
error: ⚠️ `deno bundle` was removed in Deno 2.
See the Deno 1.x to 2.x Migration Guide for migration instructions: https://docs.deno.com/runtime/manual/advanced/migrate_deprecations
```
`deno bundle --help` now produces:
```
⚠️ `deno bundle` was removed in Deno 2.
See the Deno 1.x to 2.x Migration Guide for migration instructions: https://docs.deno.com/runtime/manual/advanced/migrate_deprecations
Usage: deno bundle [OPTIONS]
Options:
-q, --quiet Suppress diagnostic output
--unstable Enable all unstable features and APIs. Instead of using this flag, consider enabling individual unstable features
To view the list of individual unstable feature flags, run this command again with --help=unstable
```
Before:
```
$ deno upgrade v1.xx
error: Invalid version passed
```
After:
```
$ deno upgrade v1.xx
error: Invalid version passed (v1.xx)
Example usage:
deno upgrade | deno upgrade 1.46 | deno upgrade canary
```
Also updates help text to use "shorthand version" without flags, but a
positional arg.
