If I have a pip package that installs a cli tool.. how can I use that in pants? I'm attempting to run meson to do some builds via shell_command

adhoc_tool

can run pip packages (2.16, in the

pants.backend.experimental.adhoc

backend), e.g. potentially something like

adhoc_tool(runnable="path/to:meson", ...)

where that's the address of the

meson

python_requirement

Oh hmm neat! This is in the rigth direction I think..

adhoc_tool(
    name = "meson",
    runnable=".build/requirements:reqs-libcamera#meson",
)

run_shell_command(
    name="run-meson",
    command="version",
    runnable_dependencies=[":meson"],
)

hm, so

adhoc_tool

actually runs the dependency, similar to

shell_command

, just with deeper knowledge of how to set-up and run python deps or similar, so that might need to be:

adhoc_tool(
   name="meson-output",
   runnable="...",
   args=["version"],
)

Like

shell_command

,

adhoc_tool

is for codegen though, so `output_files`/`output_directories` is important

Hmm okay. Can I pass meson -> run_shell_command?

I wonder if passing the

.build/requirements:reqs-libcamera#meson"

as a

runnable_dependency

to `shell_command`/`run_shell_command` would also work, e.g.

run_shell_command(command="meson version", runnable_dependencies=[".build/requirements:reqs-libcamera#meson"])

I don't know exactly the name that that dep will appear on

PATH

, though (e.g. it could be called

reqs-libcamera#meson

literally, I think).

=D

pants run .build:ruuun-meson
1.0.1

run_shell_command(
    name="ruuun-meson",
    command="meson --version",
    runnable_dependencies=[".build/requirements:reqs-libcamera#meson"]
)

nice!

Thank you stranger.
