Consumers resolve liblogosdelivery at the revision these bindings were written against, instead of pinning it themselves, and build it through the task here rather than reimplementing logos-delivery's flags. srcDir points at an empty directory, so nothing is contributed to a dependent's Nim path.

### Package
|
|
version = "0.1.0"
|
|
author = "Logos"
|
|
description = "Go bindings for Logos Delivery"
|
|
license = "MIT or Apache License 2.0"
|
|
|
|
# This is a Go module. The Nimble package exists so consumers get a
|
|
# liblogosdelivery whose C ABI matches these bindings.
|
|
#
|
|
# Pinned to a commit because logos-delivery's version does not move per release
|
|
# yet: every revision is 0.38.1, so a range cannot express "at least the one
|
|
# that has the liblogosdelivery task". Once it publishes versioned tags this
|
|
# becomes a range, and consumers can then upgrade without a release here.
|
|
#
|
|
# srcDir points at an empty directory and the Go trees are skipped, so nothing
|
|
# is contributed to a dependent's Nim path.
|
|
srcDir = "internal/nimble/src"

### Dependencies
|
|
requires "nim >= 2.2.4"

### Helpers
|
|
|
|
proc nimblePkgDir(name: string): string =
|
|
## `nimble path` reports where a dependency was installed. It prints a banner
|
|
## on stdout and exits 0 even when the package is missing, so take the last
|
|
## line and check it.
|
|

### Tasks
|
|
|
|
task liblogosdelivery, "Build the liblogosdelivery these bindings link against":
|
|
## Delegates to logos-delivery's own build task.
|
|
## Consumers set NIM_PARAMS (e.g. -d:disable_rln) and LIBLOGOSDELIVERY_OUT;
|
|
## neither is decided here.
|
|

|

|
|
exec "nimble liblogosdelivery"
|
|
|
|

|
|
