Using dylan-compiler interactively

The interactive mode of dylan-compiler allows you to carry out multiple development tasks over a period of time without having to restart the console compiler each time. To start the console environment in interactive mode, enter dylan-compiler without any arguments at a shell. For example:

$ dylan-compiler
Welcome to Open Dylan, Version 2020.1pre.

For documentation on Open Dylan, see http://opendylan.org/documentation/.
See http://opendylan.org/documentation/getting-started-cli/ for an introduction to the command line tools.

Type "help" for more information.

If you’ve used the Open Dylan IDE on Windows, note that using dylan-compiler interactively is similar to working in the IDE’s interactor.

You can find a list of command groups by entering the command help. The command groups in the console compiler are:

You can use help -group group-name to view the available commands and properties of a specific group. You can also use help command-name to view the full documentation of a command. We can see the kind of information available by looking at the help entry for the help command:

> help help
Usage: :HELP [options*] [command]

If specified with no arguments, HELP shows a list of all commands
with a one line description. Help can display command options by
specifying the name of the command. Additionally, it can display
group or property help by specifying the GROUP or PROPERTY option.

Therefore, to find out what commands exist within the PROJECT command group, type:

For documentation on a group, use:    HELP -GROUP group.

For a complete list of commands, use: SHOW COMMANDS

Then, to examine the OPEN command, type:

> help open
Usage: OPEN file

Properties can be displayed via the show command. For example to see the value of the “projects” property listed previously, use show projects.

To exit the console environment, use the command exit.
