does please allow some kind of substitution in the config file? I know I can define a buildconfig.foo and use that in build scripts s CONFIG.FOO, but can I also refer to such values from other configuration values?

also just a shout out that please is awesome! As a xoogler it's wonderful to have so many familiar comforts from blaze without the end user complexity of bazel ;)

Hi all. Wondering if it's possible to define a remote_file rule whose url depends on the values of the $OS and $ARCH environment variables. I want to build a please rule which can download a python-build-standalone distribution for the system currently building the rule, so I'm thinking it would be nice to write a bit of code which can map from $OS and $ARCH to the relevant LLVM target triple for python-build-standalone, then construct the URL for a given release on github and go and fetch it. Any advice welcome!

Looking for some advice on how to resolve this. I'm pretty positive that it's upset about the # character, given https://pkg.go.dev/cmd/cgo:

Also for security reasons, only a limited set of characters are permitted, notably alphanumeric characters and a few symbols, such as '.', that will not be interpreted in unexpected ways. Attempts to use forbidden characters will get a "malformed #cgo argument" error.

Hey folks! I've been eyeing please for the purpose of handling a mono repo, I was hoping maybe some folks could bounce some ideas with me on structure of the mono repo and the way to finagle myself into some lovely ideas. Currently I want to use please to explicitly handle building of containers that we can then use during a deployment pipeline (think CNAB style) . I've browsed the terraform pleasing, and unfortunately, I don't think it'll work for me primarily because I think it's more opinionated than I want it to be. I don't know if I WANT it to handle the terraform executable (bad of me I know...), or that I want it to manage providers. So I started on my adventure and would love some other great thoughts if they are available.

I'll continue my thoughts in the thread if anyone is interested and would like to chime in I'd love to hear some thoughts. :)

Hello! I'm struggling to understand how to use go_mod_download to resolve a circular go package problem. Specifically, I'm trying to add a dependency on the go opentelemetry module. I've tried quite a lot of things but consistently come back to errors either along the lines of:

failed to compile go.opentelemetry.io/otel/propagation: package cycle detected:
go.opentelemetry.io/otel/propagation
 ->go.opentelemetry.io/otel/trace
 ->go.opentelemetry.io/otel/internal/global
 ->go.opentelemetry.io/otel/propagation

... or, with various attempts to refactor out a go_mod_download for go.opentelemetry.io/otel and then reuse that as the download parameter to multiple go_module rules, something like this:

failed to compile go.opentelemetry.io/otel/propagation: package cycle detected:
go.opentelemetry.io/otel/propagation
 ->go.opentelemetry.io/otel/propagation

Can anyone point me to some working examples elsewhere, some documentation, or some other hints on how to resolve this? Thanks in advance!

Hello all! Is there a way to configure the location of the build directory, which is something like: TMPDIR={PROJECT_ROOT}/plz-out/tmp/ directory? The issue is it often results in a long file name and that is causing Unix socket binding related issues.

Hello, I'm having trouble using please. I'm trying to build ipxe with some custom config, so I have to copy a file into the newly downloaded ipxe sources, but I'm having a hard time doing it:

name = 'ipxe'
version = '1.21.1'

url = 'https://github.com/' + name + '/' + name + '/archive/refs/tags/v' + version + '.zip'

extract = new_http_archive(
    name = name + '_' + version,
    urls = [url],
    strip_prefix = name + '-' + version,
    build_file = name + '.BUILD',
)
# here I tried all sequences described here
# https://please.build/build_rules.html
# none worked except 'hash'
extract_loc = '$(out_location ' + extract + ')'

patch = genrule(
    name = 'patch',
    srcs = {
        'config_h': ['config.h'],
    },
    outs = {
        'config_h': ['config.h'],
    },
    tools = {
        "cp": ["echo"],
    },
    cmd = [
        '$TOOLS_CP "${SRCS_CONFIG_H}" AA' + extract_loc + 'AA ${OUTS_CONFIG_H}> /tmp/here'
    ],
    deps = [extract],
)

filegroup(
    name = 'ipxe',
    deps = [extract, patch],
    visibility = ['PUBLIC'],
)

The replacement sequence end up being empty (except for hash), so nothing between the 'AA'.
How can I add config.h in the newly downloaded sources?
Thanks,
Hugues

Can someone help me understand the please way to use a specific version of something like a kotlinc to build a kotlin module? For example I have created a way to download and extract a kotlinc compiler to a specific directory in plz-out/gen/. I'd then like to expose a command (or tool possibly) that all kotlin projects can use based on this 'pinned' version of kotlinc. I thought the $(out_location) to my remote_file //path/to:target would work but it gets put into a bash script that can't be referenced from within the build env bash env.

This happens when I import the lib in go like:

fyi the library itself is declared and build successfully like (all deps are also build OK):

go_module(

    module = "github.com/jackc/pgx/v5",
    version = "v5.2.0",
