Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

REACT NATIVE IOS vs ANDROID FONT USE

Tested for React Native 0.41+

IOS:
- Place the fonts in the assets and make sure they are bundled along
- On iOS, fontFamily in Text match the Font Family name as described in Font Book (macOS). Font weights can be specified exactly.

ANDROID:
On Android, there are two ways of using fonts:

{ writeScriptBin, runCommand, xterm }:

let
  nixposition = writeScriptBin "nix-position" ''
nix-position () {
    usage () {
        echo "Usage: nix-position <attribute-path-under-pkgs>"
        echo "Shows the Nix source file for a given attribute path."
    }
    if [ $# -ne 1 ]; then usage; return -1; fi

React Native Trouble

Updating to macOS Sierra is causing trouble with React Native due to some of the Node.js and system utilities it uses. Specifically the watch utility fails due to a limit on the number of files which can be opened at a time.

The following command shows the current limit.

launchctl limit maxfiles

nix-shell and Shebang Lines

A few days ago, version 1.9 of the Nix package manager was released. From the release notes:

nix-shell can now be used as a #!-interpreter. This allows you to write scripts that dynamically fetch their own dependencies.
