SQL Formatter

Build Status

This is a simple SQL formatter that handles formatting whitespace and capitalization of keywords. I originally wrote it for the purpose of learning Elm, but it soon became a project where I could try out languages that I'm unfamiliar with and see how many different languages can be compiled down to JavaScript. Most of the languages used, plus a lot of others, can be found here.

The app logic in each language is compiled to JavaScript using various Webpack loaders, some of which I implemented as wrappers around shell commands. The current languages are:

Setup

Install npm dependencies first with npm install, then follow the steps for each language below.

Dart

Find the correct Dart SDK URL for the desired version and OS here, then run the following:

mkdir -p "$HOME/.dart"
curl -L <dart-sdk-url> -o "$HOME/.dart/dart.zip"
unzip -q "$HOME/.dart/dart.zip" -d "$HOME/.dart"
export PATH="$HOME/.dart/dart-sdk/bin:$PATH"
pub get

ElixirScript

First, install Erlang and Elixir. On Mac, you can install Erlang with brew install erlang. To install Elixir, I recommend using Kiex.

Then install ElixirScript:

export EXS_VERSION=56cb2c5
mkdir -p "$HOME/.elixirscript/$EXS_VERSION"
curl -o- -L https://s3.amazonaws.com/mrdziuban-resources/elixirscript-$EXS_VERSION.tar.gz -o "$HOME/.elixirscript/elixirscript-$EXS_VERSION.tar.gz" | tar xvzf - -C "$HOME/.elixirscript/$EXS_VERSION"
export PATH="$HOME/.elixirscript/$EXS_VERSION/dist/elixirscript/bin:$PATH"

Elm

Install Elm packages:

$(npm bin)/elm-package install

ES6

The ES6 build doesn't require any additional dependencies!

Fable

Install F#. On Mac, you can run brew install mono. On Linux, check out the docs.

GopherJS

First, install Go 1.8, then run:

go get -u github.com/gopherjs/gopherjs

Opal

First, install Ruby if you don't already have it. I recommend using RVM. Then run:

bundle install

PHP

Install PHP (any version 5.3-5.6 should work fine), then install PHPUnit:

mkdir -p "$HOME/.phpunit/bin"
curl -sL https://phar.phpunit.de/phpunit-4.8.phar -o "$HOME/.phpunit/bin/phpunit"
chmod +x "$HOME/.phpunit/bin/phpunit"
export PATH="$HOME/.phpunit/bin:$PATH"

PureScript

Install psc-package and install dependencies:

export PSC_PACKAGE_VERSION=0.2.5
mkdir -p "$HOME/.psc-package/$PSC_PACKAGE_VERSION"
# Replace macos with linux64 if necessary
curl -o- -sL https://github.com/purescript/psc-package/releases/download/v$PSC_PACKAGE_VERSION/macos.tar.gz | tar xzf - -C "$HOME/.psc-package/$PSC_PACKAGE_VERSION" --strip-components 1
export PATH="$HOME/.psc-package/$PSC_PACKAGE_VERSION:$PATH"
psc-package update

Rust

Rust has the most experimental compilation process, using support for WebAssembly via nightly builds. Run the following:

# Install Rust
curl -L https://sh.rustup.rs | sh -s -- -y --default-toolchain=nightly
source ~/.cargo/env
rustup target add wasm32-unknown-unknown
cargo install cargo-web

Scala.js

Run the following to setup SBT:

export SBT_VERSION=0.13.15
mkdir -p "$HOME/.sbt-bin/$SBT_VERSION"
curl -o- -L https://dl.bintray.com/sbt/native-packages/sbt/$SBT_VERSION/sbt-$SBT_VERSION.tgz | tar xvzf - -C "$HOME/.sbt-bin/$SBT_VERSION" --strip-components 1
export PATH="$HOME/.sbt-bin/$SBT_VERSION/bin:$PATH"

Development

Compile

Compile all code to JavaScript:

npm run compile

Compile certain languages

The compile command accepts comma-separated only and exclude arguments to filter what languages are compiled, e.g.

# Only compile ES6 and Opal
npm run compile -- --env.only es6,opal

# Compile everything but GopherJS and Dart
npm run compile -- --env.exclude gopherjs,dart

Run

Run the Webpack dev server:

npm run dev

Note: The dev command also accepts the only and exclude arguments mentioned above

Then visit http://localhost:8000 in your browser.

Test

Tests are run using a variety tools to match the different languages. To run them:

npm run test

Build for production

npm run dist

Note: The dist command also accepts the only and exclude arguments mentioned above

Deployment

Deployment to GitHub pages is scripted.

You can’t perform that action at this time.
