Source Maps
|
|
===========
|
|
|
|
This project implements a Dart pub package to work with source maps. The
|
|
implementation is based on the [source map version 3 spec][spec] which was
|
|
originated from the [Closure Compiler][closure] and has been implemented in
|
|
Chrome and Firefox.
|
|
|
|
In this package we provide:
|
|
* Data types defining file locations and spans: these are not part of the
|
|
original source map specification. These data types are great for tracking
|
|
source locations on source maps, but they can also be used by tools to
|
|
reporting useful error messages that include on source locations.
|
|
* A builder that creates a source map programatically and produces the encoded
|
|
source map format.
|
|
* A parser that reads the source map format and provides APIs to read the
|
|
mapping information.
|
|
|
|
Some upcoming features we are planning to add to this package are:
|
|
* A printer that lets you generate code, but record source map information in
|
|
the process.
|
|
* A tool that can compose source maps together. This would be useful for
|
|
instance, if you have 2 tools that produce source maps and you call one with
|
|
the result of the other.
