Dlings

Welcome to dlings. This project aims to teach you how to program in D. If the name doesn't sound strange, it's because you might have heard of rustlings or ziglings. In fact, this is heavily based on rustlings. If you're familiar with how rustlings work, you will have no trouble getting started with dlings.

Getting started

Dependencies

• argparse
• fswatch
• toml

Clone the repository

git clone [email protected]:iK4tsu/dlings.git
cd dlings

Using DUB

dub build -b release
./dlings --help

Installing with Meson

Note: DUB prioritizes dmd when building dependencies. Since Meson is using DUB's local repository to find dependencies, you must ensure both Meson and DUB are using the same compiler. This can be done by passing the --compiler argument to DUB, and setting the DC environment variable when invoking Meson. Pay attention to the steps below.

Manually fetch and build dependencies

dub fetch <dependency>
dub build <dependency>

Note: You can choose another compiler with --compiler

dub build <dependency> --compiler=dmd

This will build DUB dependencies and place them in your DUB local repository.

Now that we have all needed dependencies in DUB's local repository, we can install dlings:

DC=dmd meson setup <builddir> --buildtype=release
ninja -C <builddir> install
dlings --help

By default, Meson will use the system's install path. You can change it with --prefix.
If you want to install dlings to $HOME/.local/bin/ then:

DC=dmd meson --prefix="$HOME/.local/" setup <builddir> --buildtype=release
ninja -C <builddir> install
dlings --help

Note: If Meson fails due to sub-dependency issues, you might need to use dub-build-deep to fetch and build your DUB dependencies.

Dlings Command Line

Arguments

argument	description
--help | -h	Prints the help menu
--color	Colorize the output. If value is omitted then 'always' is used.
--emoji	Enable emoji output. If value is omitted then 'always' is used.

Commands

command	description
hint	Prints an exercise's hint
run	Examines a single exercise
verify	Runs all exercises by the recommended order
watch	Verify in interactive mode

Note: use '--help' with a command for more information about it.

Colors and Emojis

By default, dlings will auto-detect whether or not to use colored output and emojis if the respective optional arguments are not used. Dlings depends on argparse to detect if colors can be used. If the environment variable NO_EMOJI is defined emojis won't be used.

The following sequence disables colors and emojis:

NO_COLOR=1 NO_EMOJI= dlings --help

Status

This project is in its early days. Currently, only exercises used for testing are available.
