checksum and "start server" should always start the first time

[frederikhors]

If I have a task like this:

start_server:
  sources:
    - "**/*.go"
  method: checksum
  cmds:
    - go run ./cmd/app

it will run fine just the first time.

The second time (from command line launched with: task start_server -w) it will not because it prints:

Task "start_server" is up to date.

It should always start the first time I think, right?

Hi @frederikhors,

I think I disagree. This makes sense for your use case (having a HTTP server up) but won't make sense for other use cases. For example, if you're watching a task that compiles a static web site, it makes sense to skip if it's already compile, even if you're using --watch.

I think you solve this by reworking your Taskfile like this:

version: '2'

tasks:
  run:
    deps: [build]
    cmds:
      - ./app

  build:
    cmds:
      - go build -v -o ./app ./cmd/app
    method: checksum
    sources:
      - '**/*.go'

This way, by watching run, it'll only compile if necessary, but always run.

@frederikhors Closing this since it's been almost a month.

If you still have questions, let me know.

@frederikhors Create a task always-start and then add it as a dependency to the dev server task.

  dev:
    deps: [always-start, build:clean:generate, build:script]

  always-start:
    cmds:
      - echo "Always run" >/dev/null
    status: [ 1 = 0 ]
    silent: true

For those running into this in 2024, you can now solve this by setting method: none
