This is an independent, simple implementation of an encoder for the BinaryAST format.
The main AST schema is defined in src/schema.ts and derived
from es6.webidl.
The src/parse_js.ts file contains code to lift a parsed
JSON representation of the AST (produced by the shift parser),
into the typed schema, as well as identifying the scopes in
which names are bound, which names are captured in inner
function scopes, building the string table, etc.
The main program logic is defind in src/index.ts.
The actual encoding logic is not yet implemented, but will
go into src/encode_binast.ts
After checkout, run npm install to initialize the node_modules
directory.
Then, npm run build will compile the TypeScript to JS and
place the results in the dist subdirectory.
Then, npm run encode <FILE> <DIR> will encode a file (i.e.
run the generated dist/index.js script on the given <FILE>,
dumping results in <DIR>).
Currently the resulting files are dumped as follows:
* `<DIR>/section-01-string-table` contains the string table dump.
* `<DIR>/section-02-tree` contains the tree dump
* `<DIR>/full.binast` contains the concatenation of the two above files.
* `<DIR>/original.js` contains the original js file that was encoded.
