Report an API-call warning with full context

Mirrors .report_api_error() but for tryCatch(warning = ...) handlers. Emits, in order:

Usage

.report_api_warning(w, hint = NULL, args = list())

Arguments

w

warning condition (the w from function(w) in tryCatch).

hint

character. Same semantics as .report_api_error()'s hint. If NULL, defaults to "Request emitted a warning".

args

optional named list of caller arguments to dump.

Value

Invisibly NULL. Called for its side effects.

Details

1. A timestamped friendly hint (brace-interpolated against the caller env),

2. A dump of the function call's arguments,

3. The actual warning message (conditionMessage(w)).
