Helpers for rocambole AST token manipulation
npm install rocambole-tokenHelpers to manipulate rocambole
AST tokens.
Created mainly to be used by
esindent and
esformatter.
Right now all methods ignores the loc and range info of the tokens, this is
by design since updating the range and loc info on a large JS program
multiple times can be very expensive. It's better to write a separate tool to
sanitize this info and that can be executed as a separate step.
Also important to note that right now rocambole doesn't add any reference on
the token itself to the nodes that contain that token, so if you remove a token
that happens to be the startToken or endToken of any node you might have
some conflict if you start manipulating the tokens based on the nodes,
instead of the token LinkedList. - the node.startToken might be detached
from the LinkedList.
Test coverage is pretty low so far, but since it was mostly extracted from
esformatter the methods should work as expected. I started to write some tests
just to show how I would do it but did not had the time to finish it...
(ideally tests should be written before the implementation).
