This document contains some ideas for additions to the Nix language.

Motivation

The Nix package manager, Nixpkgs and NixOS currently have several problems:

Poor discoverability of package options. Package functions have function arguments like enableFoo, but there is no way for the Nix UI to discover them, let alone to provide programmatic ways to

Just some notes from my attempt at setting up Hydra.

Setting up on NixOS

No need for manual database creation and all that; just ensure that your PostgreSQL service is running (services.postgresql.enable = true;), and then enable the Hydra service (services.hydra.enable). The Hydra service will need a few more options to be set up, below is my configuration for it:

    services.hydra = {
        enable = true;
 port = 3333;

The right way to override any highlighting if you don't want to edit the colorscheme file directly

Generalities first

Suppose you have weird taste and you absolutely want:

your visual selection to always have a green background and black foreground,
your active statusline to always have a white background and red foreground,
your very own deep blue background.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

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.

	Unicode table - List of most common Unicode characters *
	* This summary list contains about 2000 characters for most common ocidental/latin languages and most printable symbols but not chinese, japanese, arab, archaic and some unprintable.
	Contains character codes in HEX (hexadecimal), decimal number, name/description and corresponding printable symbol.
	What is Unicode?

	Unicode is a standard created to define letters of all languages and characters such as punctuation and technical symbols. Today, UNICODE (UTF-8) is the most used character set encoding (used by almost 70% of websites, in 2013). The second most used character set is ISO-8859-1 (about 20% of websites), but this old encoding format is being replaced by Unicode.
	How to identify the Unicode number for a character?

	Type or paste a character:
