FsHotWatch.Build

Plugin that runs a build command when source files change and emits BuildCompleted events for downstream plugins (like test runners and coverage checkers).

Why

Without this plugin, each tool would need to trigger its own build. The BuildPlugin centralizes builds so they happen once, and downstream plugins (TestPrune, Coverage) react to the result.

How it works

  1. You save a file
  2. BuildPlugin receives FileChanged
  3. It runs dotnet build (or your custom command)
  4. On completion, it emits BuildCompleted (success or failure)
  5. Downstream plugins like TestPrune react to the build result

The plugin guards against concurrent builds -- if a build is already running and you save again, it skips. It also skips the build entirely if only test files changed (and emits BuildSucceeded directly).

Configuration

In .fs-hot-watch.json:

{
  "build": {
    "command": "dotnet",
    "args": "build",
    "buildTemplate": "dotnet build {projects}"
  }
}

Set "build": false to disable the build plugin entirely.

Field Type Default Description
command string "dotnet" Build command.
args string "build" Arguments to the build command.
buildTemplate string -- Template for incremental builds. {projects} is replaced with changed project paths.

CLI

# Trigger a build and wait for it
fs-hot-watch build

# Check build status
fs-hot-watch build-status

Programmatic usage

From the FullPipelineExample:

daemon.RegisterHandler(
    BuildPlugin.create
        "dotnet"          // command
        "build"           // args
        []                // environment variables
        daemon.Graph      // project graph
        []                // test project names (to skip build-only-test-changes)
        None              // build template
        None              // getCommitId for caching
)
