984b0dd29c Add generate-docs command to build task
The Swift Docc has to run in a Linux container to be able to build the
documentation, as it needs access to the inotify.h header files.

This is the most convenient option when you need full coverage of a growing directory tree.
## Excluding Items
You can tell the `Inotify` actor to ignore certain file or directory names. Excluded names are skipped during recursive directory resolution (so no watch is installed on them) and silently dropped from the event stream:
```swift
let inotify = try Inotify()
// Ignore version-control and build directories
await inotify.exclude(names: ".git", "node_modules", ".build")
try await inotify.addWatchWithAutomaticSubtreeWatching(
forDirectory: "/home/user/project",
mask: [.create, .modify, .delete]
)
```
Use `isExcluded(_:)` to check whether a name is currently on the exclusion list.
## Event Masks
`InotifyEventMask` is an `OptionSet` that mirrors the native inotify flags. You can combine them freely.

## Build Tool
The package ships with a `task` executable (the `TaskCLI` target) that serves as the project's build tool. It automates running tests and generating documentation inside Linux Docker containers, so you can validate everything on the correct platform even when developing on macOS.
Because of a Swift Package Manager Bug in the [package dependency resolution][swiftpm-bug], the executable needs to be run using the `task.sh` shell script.
[swiftpm-bug]: https://github.com/swiftlang/swift-package-manager/issues/8482
### Tests
The package ships with a `task` executable (the `TaskCLI` target) that serves as the project's build tool. It spins up a Docker container running `swift:latest` on Linux and executes the full test suite inside it, so you can validate everything on the correct platform even when developing on macOS.
```bash
./task.sh test
swift run task test
```
Use `-v`, `-vv`, or `-vvv` to increase log verbosity. The command runs two passes: first all tests except `InotifyLimitTests`, then only `InotifyLimitTests` (which manipulate system-level inotify limits and need to run in isolation).
Docker must be installed and running on your machine.
### Documentation
## Documentation
Full API documentation is available as DocC catalogs bundled with the package. Generate them locally with:
```bash
./task.sh generate-docs
# Inotify library
swift package generate-documentation --target Inotify
# Task build tool
swift package generate-documentation --target TaskCLI
```
Then open the files in the newly created `public` folder.
Or preview in Xcode by selecting **Product > Build Documentation**.

Internally this listens for `CREATE` events carrying the ``InotifyEventMask/isDir`` flag and installs a new watch with the same mask whenever a subdirectory appears.
### Excluding Directories
When watching large trees you often want to skip certain subdirectories entirely — version-control metadata, build artefacts, dependency caches, and so on. Call ``Inotify/Inotify/exclude(names:)`` **before** adding a recursive or automatic-subtree watch:
```swift
let inotify = try Inotify()
await inotify.exclude(names: ".git", "node_modules", ".build")
try await inotify.addWatchWithAutomaticSubtreeWatching(
forDirectory: "/home/user/project",
mask: .allEvents
)
```
Excluded names are matched against the last path component of each directory during resolution and are also filtered from the event stream, so you never receive events for items whose name is on the exclusion list.

The build tool for the Swift Inotify project.

`TaskCLI` is a small command-line executable (exposed as `task` in `Package.swift`) that automates project-level workflows. Its primary purpose is running integration tests and generating documentation inside Linux Docker containers, so you can validate inotify-dependent code on the correct platform even when developing on macOS.
Because of a Swift Package Manager Bug in the [package dependency resolution][swiftpm-bug], the executable needs to be run using the `task.sh` shell script.
[swiftpm-bug]: https://github.com/swiftlang/swift-package-manager/issues/8482

### Generating Documentation

This copies the project to a temporary directory, injects the `swift-docc-plugin` dependency via `swift package add-dependency` (if absent), and runs documentation generation inside a `swift:latest` Docker container. The resulting static sites are written to `./public/inotify/` and `./public/taskcli/`, ready for deployment to GitHub Pages.
