so the issue I'm seeing in 1.3/1.4-dev is the compile getting stuck in:

@adventurous-art-72916 uploaded a file: Untitled

repeated a lot in the stack trace

though it never stack overflows

oooh

@witty-crayon-22786 - so I managed to trick pants to use the fixed zinc code from https://github.com/sbt/zinc/pull/193. Would it be possible to get that fix into 1.4 dev?

Hi everyone, I’d like to run a

:load script.scala

command after starting a scala repl At the moment, my steps are: 1) ./pants repl src/:: 2) :load script.scala Has anyone been able to load a script automatically after the repl loads?

Is anybody using pants with kind-projector? I’m struggling to get it to work.

I’ve read through this, and I still can’t seem to get it right. https://www.pantsbuild.org/scalac_plugins.html

Nevermind. Finally figured it out via examples.

@quiet-garden-96241 you might be able to do via a python test

# repl complains if stdin is not a tty
master, slave = pty.openpty()

replProcess = Popen(['./pants', 'repl', ...], stdin=slave, stdout=PIPE, stderr=PIPE)

ttyIn = os.fdopen(master, 'w')
yield (replProcess, ttyIn)

if replProcess.poll() is None:
  replProcess.terminate()
replProcess.wait()

I was trying to do

scala_library(
  dependencies=[
  ],

  scalac_plugins=[
    '3rdparty/jvm/org/spire-math:kind-projector',
  ]
)

But I needed to do

scala_library(
  dependencies=[
    '3rdparty/jvm/org/spire-math:kind-projector',
  ],

  scalac_plugins=[
    'kind-projector',
  ]
)

I now understand what the docs are saying about

scalac-plugin-dep

. That could definitely use some more clear verbiage. Maybe I’ll make a doc PR sometime

Does pants have anything like sbt’s

~compile

? Like a file watcher that automatically re-runs compile?

don’t think so

is there a command for getting the history for a specific target? the use case is, we want to know if the last n commits ever touched this specific target

not from pants, but usually

git log <target's dir>

is accurate enough

okay

@quiet-garden-96241 i've done something like

cat <(echo ':load script.scala') - | ./pants repl src/::

before. you do have to press ctrl-d or something twice to get out of it, though

is anyone using the pants webpack plugin?

what's your story on incremental builds? it doesn't seem possible to use

webpack --watch

in conjunction with the pants stuff

@blue-fish-35856 thanks for posting that snippet. was it mostly not clear how both dependencies and scalac_plugins need to be provided, or were there other confusing bits too?

It wasn’t clear to me that I had to add it to dependencies for it to be in scope, so that I could then use it in plugins. That part seems like it’s just a misunderstanding of the pants paradigm on my part. I had thought you could just specify the qualified path to the plugin target in the plugins section. And then, after I understood that, I began to understand that things in

scalac-plugin-dep

aren’t automatically included as plugins, it’s just a bunch of dependencies that are accessible everywhere without adding them to dependencies. @aloof-angle-91616

sorry, slack just updated. that makes sense -- i wasn't familiar with using scalac plugins and wanted to check.

Greetngs, pants gurus <!here>. I'm having difficulty getting "pragma: no cover" to have an effect when running python tests with coverage

I've added the comment to a number of function definitions in a particular module, but the coverage report output continues to show the same line count and coverage statistics for that module.

Is it true that I should expect that directive to work with pantsbuild as it does when I'm not using pantsbuild?

And, would anyone have suggestions for how to begin to debug why it isn't working

anyone have a sense for whether I should cherry-pick this to the 1.3 release branch? I'm unclear on what the policy is for updating existing releases vs. putting features in upcoming ones: https://github.com/pantsbuild/pants/pull/4930#pullrequestreview-66649051

@bright-apartment-76721: see https://www.pantsbuild.org/release_strategy.html#release-cadence ... ask for it to be marked
