# Run ethercalc on port 80 ( http://localhost/ )
docker-compose up -d

Config database

set env vars:
  REDIS_PORT REDIS_HOST REDIS_SOCKPATH REDIS_PASS REDIS_DB OPENSHIFT_DATA_DIR

Defaults:
  REDIS_HOST = localhost   
  REDIS_PORT = 6379   
  OPENSHIFT_DATA_DIR= process.cwd!

Send email

Optional - Send email formulas requires OAuth2 & cron  e.g. =email(to, subject, body), =emailAt(time, to, subject, body)

OAuth2 - Set environment vars
1) Tutorial: follow the tutorial to get the 4 environment vars http://masashi-k.blogspot.com.au/2013/06/sending-mail-with-gmail-using-xoauth2.html
2) Set 4 environment vars - see [src/emailer.ls] vars: user, clientId, clientSecret, refreshToken
Tested using gmail, have not tested with other providors

Cron - Required for emailAt formulas.
See *curl* in [.openshift/cron/minutely/timetrigger] for openshift version (openshift](openshift.redhat.com)
The curl checks the database for unsent emails and updates the database after sending.

Please see API.md for the API Blueprint, or the online version at Apiary.

Specify a specific host and/or a different port for the service.

By default EtherCalc listens at 0.0.0.0:8000 (all IPv4 interfaces).

openssl genrsa -out ethercalc-key.pem 1024
openssl req -new -key ethercalc-key.pem -out certrequest.csr
openssl x509 -req -in certrequest.csr -signkey ethercalc-key.pem -out ethercalc-cert.pem
ethercalc --keyfile ethercalc-key.pem --certfile ethercalc-cert.pem

Useful when running behind a proxy without WebSocket support.

Useful when setting up EtherCalc as a public REST API server.

Useful when running under an URL rewriter. If running with a nginx reverse proxy, please add this section:

    location /zappa/socket/__local/ {
        rewrite (.*) /path/prefix$1;
    }

Offers read-write vs. read-only modes. See issues #1 and #4 for details on setting this up.

Runs a single-thread background loop with vm.createContext instead of webworker-threads.

Useful for running custom functions in server side that requires full VM access.

Deletes a spreadsheet's content after N seconds of inactivity. Activities include accessing with REST API as well as Web UI, including moving the active cell cursor on an opened page.
