|
// Why this file exists:
|
|
// We have two places in the tool where we need to do source maps:
|
|
// 1. Loaded isopacks, which use a special custom source map cache
|
|
// 2. Transpiled tool code from Babel
|
|
//
|
|
// In order to avoid crazy bootstrapping, it would be nice to be able to add
|
|
// functions to look for source maps, so that we can call
|
|
// sourceMapSupport.install as early as possible, and not worry about having
|
|
// the right data structures around.
|
|
//
|
|
// This module maintains a stack of source map retrieval functions, which are
|
|
// called in reverse order until one returns a truthy value.
|
|
|
