This macro takes an issue pattern and an optional 'reason'.

When the BLOCKED_GITHUB_API_KEY environment variable is found this macro will attempt to find the status of the referenced issue. If the issue has been closed blocked will emit a warning containing the optional 'reason'.

Because this requires network access, it is recommended this is only run in CI builds so as to not slow down the edit-run-debug cycle.

// An attribute-like procedural macro is on the todo-list
#![feature(proc_macro_hygiene)]

use blocked::blocked;
# fn hacky_workaround() {}
# fn main() {
blocked!("1", "This code can be removed when the issue is closed");
hacky_workaround();

// The reason is optional
blocked!("1");
# }
