scope-analyzer change log

All notable changes to this project will be documented in this file.

This project adheres to Semantic Versioning.

2.1.1 / 2020-03-06

• use dash-ast for faster tree walking. anecdotally results in a 10-20% analysis speedup.

2.1.0 / 2020-03-06

• add deleteScope() and clear() methods to delete scope information from a single node or an entire tree. Thanks @fabiosantoscode!

2.0.6 / 2020-03-05

• detect the .value part of a shorthand property as the variable reference, instead of the .key part.

This is a bugfix only for ASTs that were already modified prior to being crawled with scope-analyzer. Thanks @fabiosantoscode!

2.0.5 / 2018-06-25

• detect catch(param){} bindings

2.0.4 / 2018-05-22

• fix class method definition names being counted as references to outer variables.

2.0.3 / 2018-04-20

• revert to custom walker, acorn.walk behaviour is different and not faster

2.0.2 / 2018-04-20

• fix valid references that occur above a value is declared in source code

2.0.1 / 2018-03-30

• always initialise scope on the root node, so that undeclared names can be attached

2.0.0 / 2018-03-08

• add support for ES5 environments (Node 0.10+)
• scan.getBinding() now also returns bindings for undeclared identifiers. binding.definition will be undefined for undeclared identifiers.

1.3.0 / 2018-01-13

• add binding.remove(node) to remove a reference to a binding from the list of references. use binding.isReferenced() to check if there are any references left.

1.2.0 / 2018-01-02

• track uses of undeclared variable names. use getUndeclaredNames() on the root scope to get a list of undeclared names used in the AST.

1.1.1 / 2018-01-02

• fix import { a as b } being counted as a reference to a

1.1.0 / 2017-12-26

• account for import declarations
• rename analyze to crawl (analyze is still available as alias)
• some tests

1.0.0 / 2017-11-15

• initial release
