# --- Parse command line ---
#
# Author: Magnus Engström
# Email: magnus@gisab.se
# File: cmdline_parse
#
# Description
# -----------
# Parses the commandline and
# returns a hash with the
# switch as key and the
# value as value :)
# --------------------------
class Commandline
def Commandline::parse()
params = Hash::new() # Could be useful to have something to put the commandline in ;)
key = false # Just a really ugly hack to keep track on if we're reading key or value
foo = '' # Keeps the key name
# Iterate through the command line ($*) and put it in the params hash
$*.each { |param|
key = ( key == true ? false : true ) # Negate the value of key
if(key)
foo = param
else
params[foo] = param
end
}
# Validate the command line.
# Every key should begin with at least one '-' and have a value
if( !key ) # If key equals true, then the user should enter one more parameter
passed = true
params.each { |key, value| # Iterate through all parameters
passed = false if(key[0].chr() != '-') # Doesn't it start with a '-'? Not passed...
passed = false if(value == '') # I really want a value here, not just an empty string
}
end
# Return params if check passed, else return -1
passed ? params : -1
end
