Refactorings from proptietary libraries code to ES5, ES6 constructions.
See also more general project called lebab
NOTE: The code of scripts DOES NOT cover all possible scenarios, some usages of api may not me matched, or we just do not want to automate their usage (working on safest possible scenarios, but sometimes it is better to convert border cases by humans). You are always welcomed to CONTRIBUTE another variants.
Currently available refactoring scripts:
- all
- dojo/array.indexOf
- dojo/array.map
- dojo/df.keys
- dojo/dstring.trim
- dojo/hitch2bind
- dojo/lang.isArray
- dojo/lang.isFunction
- dojo/partial2bind
- js/for2map
- js/object.keys
- js/substring.length
- js/substring.tail
- lodash/array.forEach
- node/mkdirp.sync
Install external tools:
npm install -g grasp #yes for now as global, sorry
Apply refactoring (on sample files)
< samples/hitch2bind/hitch2bind.before.js src/dojo/hitch2bind.v01 # NOTE: should apply all versions step by step
Check what is changed and if behaves same (naive samples for now):
# before: print source and results
< samples/lodash/array.forEach.js tee /dev/fd/2 | node
# after: print source and results
< samples/lodash/array.forEach.js ./src/lodash/array.forEach.v02 | tee /dev/fd/2 | node
# for dojo samples use dnode
< samples/dojo/dstring.trim.js src/dojo/dstring.trim.v01 | tee x.js; dnode x.js; rm x.js

Study grasp.js for CLI parameters (we pass all to underlying grasp now)
There are plenty of projects to translate es6 syntax to older syntaxes. This allows you to write modern syntax and run on 'old machines'.
This project is opposite.
Helping you to CONVERT OLD CODE BASE TO NEW API AND SYNTAX. (hence anti- in the name and babel as one of 'them'.)
We are writing JavaScript from 'dark ages' (somewhere 19XX), and we are running big projects, this means we have to maintain them, for ages sometimes.
This could help to modernize them into something more readable today.
Today we are developing in dojo, so many samples may involve 'old dojo' APIs and refactoring to ES5,6 APIs, but the idea can be taken to other codes as well.
To see if you can/should refactor you can use compat-tables as UI or out CLI
We are developing in dojo. Dojo contains a lot of good ideas, but a lot of APIs is not needed anymore.
For Example
dojo/string/trim vs. String.prototype.trim
es5 features mapped to dojo apis. This is only approx mapping and for caveats you must learn both APIs, to understand if you can(not) refactor:
ES5 features mapped to dojo API, all of these except strict mode are supported in IE9.
