Reconstruct the actual output from my unit test tool report - 125 entries

When a test fails, my unit test tool reports differences between the actual output and the expected output as follow: - line in the expected output but missing in the actual output are prefixed with a dash - unexpected lines in the actual output are prefixed with a plus sign - comments added by the unit test tool are prefixed with a question mark - common lines are showed `as-is` (well, almost;) From that "diff" format, I would like to reconstruct the actual output.

Back to the Future - 3 entries

We can't just time-travel around without first making sure our code is pretty and columns are aligned. And keeping lines with at most 80 characters should help if we ever need to review the code while we're stuck in the past. This is my first challenge. I tried being creative and even did a bit of research, so I hope you enjoy it.

Sometimes databases output things differently one to another. Fixing things that are out of order will make the diffs more usable.

Reformat Cura settings - 102 entries

Cura settings are weirdly encoded... After mere replacements, you'll have to enquote two strings (infill_pattern & speed_travel) and dont forget booleans in lowercase. #format #json

Unsemantic linewrapping - 818 entries

[Inspired by a blog post I read: https://scott.mn/2014/02/21/semantic_linewrapping/. Text adapted.] Sometimes when editing a Markdown file, I wrap the lines semantically. Instead of inserting a newline at 70 columns (or whatever), or making paragraphs one long line, I put in newlines at a point that seems logical to me. This may seem silly, but it produces better diffs. Semantic linewrapping also makes editing snappier. I can delete, edit or insert sentences easily using linewise operations. Code-oriented text editors like Vim and [REDACTED] are really good at this kind of manipulation. Editing text that hasn't been wrapped semantically is a pain, though:

Song Transcription Oops - 221 entries

When transcribing vocal music to Canjo Tab you can start by finding the lowest note and assigning that to zero and working your way up from there. However, without fail, I tend to miscount the notes and when I am near done I find a lower note. I mark this with a "z". This means I have to increase all the previous ones by 1. just a sting of numbers :)

If-then-else regexp - 37 entries

Tables, Functions, Sprocs - 109 entries

In order to load some scripts into my database in the correct order I need to load tables first (t_), then functions (fn_), then stored procedures (sp_). The order of the t_ lines and the order of the sp_ lines should also match. Reorder the lines so they will load correctly.
