Creating your first project

Installing Derw

First we need to install Derw. It's recommended that you use the latest stable version of Node, though most supported versions should work. You need ts-node to run the test runner, so it's recommended to install that too.

npm install -g ts-node derw

Creating a project

Starting a project is as simple as making a directory, then initializing Derw inside it.

derw init
Initialize a directory as a Derw project.
  --dir string:		name of a directory to use as package name e.g stdlib. 
                        Defaults to current directory's name
  -h, --help :		This help text

Using templates to get started

Derw comes with some templates to get you started. Right now there is only one template: for creating a web app using Derw's html library.

To create a web template, run

derw template --template web --path src/Main.derw
Generate a Derw file from a template.
Also installs required packages.
  --path string:		path of Derw file to create
  --template web:		Template to use
  -h, --help :		        This help text

Installing editor and CLI utils

Right now the best supported editor is VSCode, with three extensions that can be used in combination to get some nice features

Install vscode-language-server

The language server supports things like inline error messages.

On the vscode store: https://marketplace.visualstudio.com/items?itemName=derw.derw-language-server

git clone https://github.com/derw-lang/derw-language-server
cp -r derw-language-server ~/.vscode/extensions/derw-language-server-0.0.1

Install Derw syntax

Derw syntax highlighting it provided in a separate extension

On the vscode store: https://marketplace.visualstudio.com/items?itemName=derw.derw-syntax

git clone https://github.com/derw-lang/derw-syntax
cp -r derw-syntax ~/.vscode/extensions/derw-syntax-0.0.1

Install auto-formatter

The auto-formatter runs on-save for files with the .derw extension

On the vscode store: https://marketplace.visualstudio.com/items?itemName=derw.derw-formatter-vscode

git clone https://github.com/derw-lang/derw-formatter-vscode
cp -r derw-formatter-vscode ~/.vscode/extensions/derw-formatter-vscode-0.0.1

Install Bash completions

If you use Bash, then you probably want some auto completion.

  • Clone this repo

  • Source the _derw_completions.sh files in your ~/.bashrc or ~/.bash_profile, using source

  • Restart bash or open a new terminal session

If you're using Linux, you probably want .bashrc. If you're using OS X, you probably want .bash_profile.

Example .bashrc or .bash_profile file:

for f in ~/dev/derw-bash-completion/_*; do source $f; done

Oh my Zsh

Use bashcompinit.

autoload bashcompinit
bashcompinit
for f in ~/dev/derw-bash-completion/_*; do source $f; done
