Rune is the interactive command line interpreter for E code.
Setting up rune
Windows: Copy the file
rune.bat and edit the settings in the file.
rune and edit it.
Add execute rights to the file by executing the shell command
chmod a+x rune.
You should now be able to execute rune and get an interactive shell.
As an alternative, rune can be started using the java executable:
java -jar e.jar --rune
Running an E script from rune
There are two ways to start an E script using rune:
First, you can give the name of the script as a command line argument.
The second way is to start the script from the E command prompt:
The second method can be faster if you want to start a script more than once, for example for testing. The java virtual machine is only started once, which can save some seconds.
The interactive E interpreter does not provide command history. Under windows, the shell has its own command history, which can be used by pressing the up and down arrow keys. If your system does not provide command history, you can try RLWrap.
