The following guide explains how to export an openproject wiki to somewhat readable openproject syntax-ed files.
The guide assumes you are running in bash shell, and can use GNU sed, and that you have the sqlite3 command utility installed.
Following UN*X philosophy, all commands should be silent and have no stdout. If you get something printed to stdout there is an error.
Recently, there had been a call for blog posts reflecting 2017 and about which path Rust should choose in 2018.
First a few words about me. I was and still am a student, and most of my coding is for learning and because it is fun. Also, coding is a great excuse for procrastinating something more important :). Having contributed to open source codebases has helped me determine that I want to do this in a day job once I'm done with my studies.
I've heard about Rust somewhere around the 1.0 release in 2015. I don't know the details any more, but most likely it was a German tech news website. I've then read on about what Rust is and its promises like zero cost abstractions, fearless concurrency or the concept of safety really stood out. My background was C++ so I also quite liked the syntax. A bit later I decided to read the the book (first edition, back then
In the best case, you should:
export.cfg, with an icon, and version numbers raised at each releaseExplanations why these things are useful for packagers, and how they are done, and done best, can be found below.
