It appears the `--prompt` flag has done nothing for some time. Perhaps,
since #13650. Classifying this as a dead functionality removal for this
reason.
Did this while working on #22021.
This commit introduces deprecation warnings for "Deno.*" APIs.
This is gonna be quite noisy, but should tremendously help with user
code updates to ensure
smooth migration to Deno 2.0. The warning is printed at each unique call
site to help quickly
identify where code needs to be adjusted. There's some stack frame
filtering going on to
remove frames that are not useful to the user and would only cause
confusion.
The warning can be silenced using "--quiet" flag or
"DENO_NO_DEPRECATION_WARNINGS" env var.
"Deno.run()" API is now using this warning. Other deprecated APIs will
start warning
in follow up PRs.
Example:
```js
import { runEcho as runEcho2 } from "http://localhost:4545/run/warn_on_deprecated_api/mod.ts";
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
async function runEcho() {
const p = Deno.run({
cmd: [
Deno.execPath(),
"eval",
"console.log('hello world')",
],
});
await p.status();
p.close();
}
await runEcho();
await runEcho();
for (let i = 0; i < 10; i++) {
await runEcho();
}
await runEcho2();
```
```

Closes #21839
We were calling `expand_glob` on our excludes, which is very expensive
and unnecessary because we can pattern match while traversing instead.
1. Doesn't expand "exclude" globs. Instead pattern matches while walking
the directory.
2. Splits up the "include" into base paths and applicable file patterns.
This causes less pattern matching to occur because we're only pattern
matching on patterns that might match and not ones in completely
unrelated directories.
This PR fixes #21658.
- `check` subcommand sees `exclude` option in `deno.json`. When some
paths passed with `check` command listed in `exclude`, they are ignored.
- When some files are listed in `exclude` and imported indirectly among
module graph, they are checked.
This PR implements the child_process IPC pipe between parent and child.
The implementation uses Windows named pipes created by parent and passes
the inheritable file handle to the child.
I've also replace parts of the initial implementation which passed the
raw parent fd to JS with resource ids instead. This way no file handle
is exposed to the JS land (both parent and child).
`IpcJsonStreamResource` can stream upto 800MB/s of JSON data on Win 11

Fixes https://github.com/denoland/deno/issues/21594
I verified locally that this fixes the problem. I'm working on testing
harness for Jupyter kernel to catch regressions like this and will
add it in a follow up PR.
This PR implements the Node child_process IPC functionality in Deno on
Unix systems.
For `fd > 2` a duplex unix pipe is set up between the parent and child
processes. Currently implements data passing via the channel in the JSON
serialization format.
Adds an `--unstable-sloppy-imports` flag which supports the
following for `file:` specifiers:
* Allows writing `./mod` in a specifier to do extension probing.
- ex. `import { Example } from "./example"` instead of `import { Example
} from "./example.ts"`
* Allows writing `./routes` to do directory extension probing for files
like `./routes/index.ts`
* Allows writing `./mod.js` for *mod.ts* files.
This functionality is **NOT RECOMMENDED** for general use with Deno:
1. It's not as optimal for perf:
https://marvinh.dev/blog/speeding-up-javascript-ecosystem-part-2/
1. It makes tooling in the ecosystem more complex in order to have to
understand this.
1. The "Deno way" is to be explicit about what you're doing. It's better
in the long run.
1. It doesn't work if published to the Deno registry because doing stuff
like extension probing with remote specifiers would be incredibly slow.
This is instead only recommended to help with migrating existing
projects to Deno. For example, it's very useful for getting CJS projects
written with import/export declaration working in Deno without modifying
module specifiers and for supporting TS ESM projects written with
`./mod.js` specifiers.
This feature will output warnings to guide the user towards correcting
their specifiers. Additionally, quick fixes are provided in the LSP to
update these specifiers:
A bit hacky, but it works. Essentially, this will check for all the
scripts in the node_modules/.bin directory then force them to run with
Deno via deno_task_shell.
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 adds unstable workspace support. This is extremely
bare-bones and
minimal first-pass at this.
With this change `deno.json` supports specifying `workspaces` key, that
accepts a list of subdirectories. Each workspace can have its own import
map. It's required to specify a `"name"` and `"version"` properties in the
configuration file for the workspace:
```jsonc
// deno.json
{
"workspaces": [
"a",
"b"
},
"imports": {
"express": "npm:express@5"
}
}
```
``` jsonc
// a/deno.json
{
"name": "a",
"version": "1.0.2",
"imports": {
"kleur": "npm:kleur"
}
}
```
```jsonc
// b/deno.json
{
"name": "b",
"version": "0.51.0",
"imports": {
"chalk": "npm:chalk"
}
}
```
`--unstable-workspaces` flag is required to use this feature:
```
$ deno run --unstable-workspaces mod.ts
```
