# About:
# there are 2 common conversions that I find myself doing:
# markdown -> html for online blog posts with mathjax
# markdown -> pdf for pdfs via pandoc
# unfortunately, if the markdown contains LaTeX, then there are different ways to escape the
# delimiters, as well as the matrix new row symbol. http://docs.mathjax.org/en/latest/tex.html#tex-and-latex-math-delimiters

# usage: `tex2jax_delim true infile.md outfile.md`

Setup for heroku for snowplow scala apps

1. obfuscate access keys in conf as: ${AWS_ACCESS_KEY_ID}
   • if you get a error like adf, make sure resolve() the config file like: ConfigFactory.parseFile(new File("conf/application.conf")).resolve()
2. add addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "0.8.0-M1") to project/plugins.sbt and .settings(com.typesafe.sbt.SbtNativePackager.packageArchetype.java_application: _*) to wherever val project is defined (project/ScalaCollectorBuild.scala)
   • this provides the sbt stage task that heroku runs to compile
   • be careful to skip every other line in plugins.sbt
3. add java.runtime.version=1.7 to system.properties in repo root
4. add worker: ./target/universal/stage/bin/name-of-my-app --config myconf.conf to Procfile in repo root, check name of executable after sbt compile stage

• don't use sh here, heroku runs Ubuntu with dash not bash
