A bridge between EmacsSpeak and the Speech Rule Engine.

Install

PrePrerequisites

Install the latest version of nvm and npm

git clone https://github.com/creationix/nvm.git

Move somewhere where you like it. E.g., ~/.nvm

Put into your bashrc:

export NVM_DIR="/home/sorge/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" "--no-use"  # This loads nvm

nvm use --delete-prefix stable --silent

export NODE_DISABLE_COLORS=1 export NODE_NO_READLINE=1

Then install the latest version of node

nvm install stable

Prerequisites

You need to have a recent installation of NodeJS and npm. Then do

npm install speech-rule-engine
npm install mathjax-node

Emacs Interaction

Test server/client

From a shell, run node math-server.js

Then from a different shell, run a client 
    nc localhost 5000
    
    In this client connection, type 
        
            enter: a+b
            
            If everything works, you'll see an S-expression come
            back.

Next Run it Through Emacs

 M-x load-file 
     emacspeak-maths.el
