added String modifier to parse-string

[andre-dietrich]

Hi, it took a while, but I had added one function modifyStream that can be used to inject strings into the parse string. I use it to define statefull macros, that inject code at compile time into the code while parsing. See, https://liascript.github.io ...

It would be great, if you could add this simple function, so that I could switch back to your repo in my project.

Regards

This check failed because of:

Could not find Elm compiler "elm-make". Is it installed?

see the travis output and not because of the new function ...

If you replace the current contents of .travis.yml with

language: elm

I think the tests should run properly :)

Just curious, what is the status on this one?
