Miscellaneous

This is a list of reminders and open questions I still wanted to look at in more detail.

CSV conversion

Next to FSharp.Data there is CSVHelper. However, it does not support FSharp types intrinsically. A stackoverflow article describes the details.

I have concluded that to read CSV files, FSharp.Data is the best. To easily write CSV files, use CSVHelper.

The configuration is set like this:

use csvStream = new IO.StreamWriter("woCancelled.csv")
let culture = System.Globalization.CultureInfo.InvariantCulture
let config = new CsvHelper.Configuration.CsvConfiguration(culture)
config.Delimiter <- ";"

use csvWriter = new CsvHelper.CsvWriter(csvStream, config)
csvWriter.WriteRecords(data)

Stress tests of CSV

There are several stress tests for CSV reading and writing:

Writing scientific papers

Print Markdown with pandoc

pandoc is a tool to convert markdown to all kinds of formats. It states:

If you need to convert files from one markup format into another, pandoc is your swiss-army knife.

You can use the yaml header in a markdown file to tell pandoc how to print it. For instance:

---
title: My Title
author: Markus Greiner
date: 2024-01-18
fontsize: 12pt
papersize: a4
geometry: margin=2cm
---

This will use paper size A4 and font 12pt when converting to pandoc, and will set the margin to 2 cm. If you want to print it landscape, do:

---
geometry: landscape
---

The conversion to pdf is done as follows:

% pandoc *.md -o mydoc.pdf

Humanizer

Humanizer meets all your .NET needs for manipulating and displaying strings, enums, dates, times, timespans, numbers and quantities. It is part of the .NET Foundation, and operates under their code of conduct.

Humanizer is an amazing library to do string conversions from programming strings to human readable strings. For instance, it handles all the PascalCase, camelCase, etc renaming, shortening of strings, even creating [Display("Family Name")] attribute handling.

Yaml

Use YamlDotNet.

Markdown

Use Markdig.

## datatools

datatools is a rich collection of command line programs targetting data conversion, cleanup and analysis directly from your favorite POSIX shell. It has proven useful for data collaberations where individual members of a project may prefer different toolsets in their analysis (e.g. Julia, R, Python) but want to work from a common baseline. It also has been used intensively for internal reporting from various Caltech Library metadata sources.

MVC, Razor, Razor Pages, MVC, and Blazor

I found a good article explaining all of this on Progress Telerik

Unix stuff

To only grep on stderr, do:

go run . 2>&1 >/dev/null | grep MyPattern
