What is this?

A place to play with Typescript

read_xml_out_csv.ts

Special case: currently, we're running tests with karma which runs tests in the browser. this file requires the file system which doesn't work in the browser. So... the file lies outside of the src folder. See its header for instructions.

Initialisation

# install tsc
npm install typescript --save-dev

# initialise tsc config file
node_modules/typescript/bin/tsc --init

# then change outdir and rootDir in tsconfig.json

# continuous compilation
node_modules/typescript/bin/tsc -w

# run the program
node dist/src/index.js

# continuous test runner (generate coverage report too, see coverage folder)
node_modules/karma/bin/karma start

# clean all
rm -rf node_modules && rm -rf coverage && rm -rf dist && rm -f npm-debug.log
npm install

# using npm
npm run clean
npm install
npm run test
npm run dist
npm run run

TODO

change over to mocha so we can test stuff that doesn't exist in browser, like file system
add more ts stuff

Watch out...

Watch out, if we add import {describe} from 'karma'; then it fails miserably! karma test won't even start up and the error message is very cryptic!

Scala:

The XML processing API which allows you to write nice readable code which has standard collection style functions, for example the following line which builds a tuple of file model and the servlet node, for each servlet node found in the file:

return XML.loadFile(file) \ "servlet" map((fileModel, _))
pattern matching for giving tuples named parameters and dealing with parameter nodes in the XML
powerful collections library for writing functional code for transforming data
