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.
Fixes https://github.com/denoland/deno/issues/25862.
npm only makes bin entries executable if they get linked into `.bin`, as
we did before this PR. So this PR actually deviates from npm, because
it's the only reasonable way to fix this that I can think of.
---
The reason this was broken in moment is the following:
Moment has dependencies on two typescript versions: 1.8 and 3.1
If you have two packages with conflicting bin entries (i.e. two
typescript versions which both have a bin entry `tsc`), in npm it is
non-deterministic and undefined which one will end up in `.bin`.
npm, due to implementation differences, chooses to put typescript 1.8
into the `.bin` directory, and so `node_modules/typescript/bin/tsc` ends
up getting marked executable. We, however, choose typescript 3.2, and so
we end up making `node_modules/typescript3/bin/tsc` executable.
As part of its tests, moment executes `node_modules/typescript/bin/tsc`.
Because we didn't make it executable, this fails.
Since the conflict resolution is undefined in npm, instead of trying to
match it, I think it makes more sense to just make bin entries
executable even if they aren't chosen in the case of a conflict.
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
```

Fixes #25813.
I initially tried doing this in `deno_semver`, where it's a cleaner
change, but that caused breakage in deno in places where we don't expect
a tag (see https://github.com/denoland/deno/issues/25857).
This does not fix wildcard requirements failing to choose pre-release
versions. That's a little more involved and I'll do a separate PR.
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).
`deno fmt --check` was broken for CSS, YAML and HTML files.
Before this PR, formatting any of these file types would return a
string, even though the contract in `cli/tools/fmt.rs` is to only return a
string if the formatting changed. This causes wrong flagging of these files
as being badly formatted even though diffs showed nothing (because
they were in fact formatted properly).
Closes https://github.com/denoland/deno/issues/25840
Partially addresses https://github.com/denoland/deno/issues/25648.
This allows packages that use `crossws` to be installed with `deno
install`. `crossws` specifies an optional peer dependency on
`uWebSockets`, but `uWebSockets` is not on npm (it is used with `git:`
or `github:` specifiers). Previously we would error on this, now we
don't error on non-existent optional peer dependencies.
Fixes #25802
markup_fmt plugin supports some HTML-like formats like Angular, Jinja,
Twig, Nunjucks or Vento, that are not supported by `deno fmt`. This PR
adds support for the extensions `njk` (Nunjucks) and `vto` (Vento).
Angular doesn't have a custom extension (it uses `html` afaik) and Jinja
and Twig are template engines written in Python and PHP respectively so
it doesn't make sense to be supported by Deno.
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`
This commit adds better handling for terminal errors when
`window` global is used. This global is removed in Deno 2,
and while we have lints to help with that, an information and
hints are helpful to guide users to working code.

Fixes rsbuild running in deno.
You can look at the test to see what was failing, the gist is that we
were trying to statically analyze the re-exports of a CJS script, and if
we couldn't find the source for the re-exported file we would fail.
Instead, we should just treat these as if they were too dynamic to
analyze, and let it fail (or succeed) at runtime. This aligns with
node's behavior.
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.

**Code Changes**
- Updated malva version to the latest in cli/Cargo.toml.

- Added test case same as the issue to assure changes success.
This commit improves error messages for unstable APIs:
- `--unstable-broadcast-channel`
- `--unstable-cron`
- `--unstable-http`
- `--unstable-kv`
- `--unstable-temporal`
By providing information and hints what went wrong and how the
error can be fixed. It reuses the same infra that was added in
https://github.com/denoland/deno/pull/21764.
This was initially added in #25399 in order to make transitioning over
from package.json to deno.json more easy, but it causes some problems
that are shown in the issue and it also means that the output of `deno
install` would have different resolution than `npm install`. Overall, I
think it's too much complexity to be smarter about this and it's
probably best to not do it. If someone needs an aliased folder then they
should keep using a package.json
Closes #25538
Closes https://github.com/denoland/deno/issues/25321
Ended up being a larger refactoring, since we're now juggling
(potentially) two config files in the same `add`, instead of choosing
one. I don't love the shape of the code, but I think it's good enough
Some smaller side improvements:
- `deno remove` supports `jsonc`
- `deno install --dev` will be a really simple change
- if `deno remove` removes the last import/dependency in the
`imports`/`dependencies`/`devDependencies` field, it removes the field
instead of leaving an empty object
The map field has been empty for years now and we don't want the emit
file to be exposed so it allows us to iterate on making the cache
faster. Additionally, it's racy/unreliable to rely on this information.
Instead, people should emit the TS files themselves using tools like
deno_emit, typescript, esbuild, etc.

This allows using npm deps of jsr deps without having to add them to the
root package.json.
Works by taking the package requirement and scanning the
`node_modules/.deno` directory for the best matching package, so it
relies on deno's node_modules structure.
Additionally to make the transition from package.json to deno.json
easier, Deno now:
1. Installs npm deps in a deno.json at the same time as installing npm
deps from a package.json.
2. Uses the alias in the import map for `node_modules/<alias>` for
better package.json compatiblity.
These now works:
```
$ deno add @std/dotenv/load
$ deno add npm:preact/hooks
```
Previously we were erroring out, because this is a "package reference"
including
a subpath.

`--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.

This commit effectively turns Deno into Deno 2.0.
This is done by forcing `DENO_FUTURE=1` env var, that was available in
the past few months to try Deno 2 changes.
This commit contains several breaking changes scheduled for Deno 2:
- all deprecated JavaScript APIs are not available any more, mostly
`Deno.*` APIs
- `window` global is removed
- FFI, WebGPU and FS APIs are now stable and don't require
`--unstable-*` flags
- import assertions are no longer supported
- "bring your own node modules" is enabled by default
This is the first commit in a series that are scheduled before the Deno
2 release.

This PR makes the logic that caches top level dependencies (things
present in import map) smarter, so we handle JSR dependencies without
root exports.
This commit deprecates "import assertions" proposal that has been
replaced with "import attributes".
Any time an import assertion is encountered a warning will be printed
to the terminal. This warning will be printed for both local and
remote files (ie. user code and dependencies).
Import assertions support will be removed in Deno 2.
