Requirements:

• Scraping: curl, ack, python
• Visualisation: R, tidyverse packages, scales

Scrape

echo "Gross;Net" > data.csv; 
python -c 'RANGE=(20000, 200000); STEPS=40; [print(int(RANGE[0] + i*(RANGE[1] - RANGE[0])/STEPS)) for i in range(1, STEPS)]' | \

1. You'll need platform-dependent binaries for SQLite4Java (that's what local dynamo is using under the hood): https://bitbucket.org/almworks/sqlite4java/src/master/
2. put them in native-libs folder at the root of your project
3. In your script you'll need to set

System.setProperty("sqlite4java.library.path", "native-libs")

4. When you run it first, it won't work. You need to skip Catalina's notarization:

This is a simple script to help me see the bytecode when plaing with Scala 3.

All it does is parallelises the calls to javap command that should available if you have JDK installed.

Installation

Just Ammonite - https://ammonite.io/

It's excellent.

This script does the following:

1. Downloads the listing of Scala 3 nightly versions from https://repo1.maven.org/maven2/org/scala-lang/scala3-compiler_3/
2. Parses and sorts them in a really silly way
3. Runs binary search, invoking scala-cli with a given file and different versions, until it hits the earliest version where the file fails to compile

E.g. if you have a file like this (from scala/scala3#15160):

example.sc
