Command-line options

By default, launching Storm Storm from the command line launches the REPL (i.e. an interactive session) for Basic Storm. This behavior can be changed by using different command-line flags.

To start a REPL of another language, pass -l <language>. For example: Storm -l bs to start the Basic Storm REPL.

To pass a string to the REPL of a language, use the flag -c. For example: Storm -l bs -c 1+2 sends the expression 1+2 to the Basic Storm REPL. This flag can of course be used without the -l flag.

To run a single function, use the -f flag. This function may not take any parameters, and not all return types are supported. Example: Storm -f foo.main.

To specify a root path, use -r. For example: StormMain -r root/ launches Storm with root/ as the root directory. The default root directory depends on your system. If you have Storm installed in your system, it resides in /usr/share/storm on most systems. Otherwise, it is the root/ directory relative to the directory of the executable file.

It is also possible to import specific directories into the package tree. This is done with the -i and -I flags. -i takes one parameter, the name of a file or directory to be imported. This file is placed in a package with the same name as the file or directory. For example Storm -i will import the contents of into the package myfile. If you wish to specify the location of the imports, use -I <package> <file> instead. For example: -I mypkg imports the file into mypkg instead. Both -i and -I works with both files and directories. These flags do not alter the default behavior, so unless you specify something else, a REPL is still launched.

Any options without a preceeding flag are treated the same as -i, i.e. as names of files or directories. So, to launch a function main inside the file, you can run: Storm -f test.main.
