Command lineΒΆ

An LSP program is executed with the following command in a console where file.lsp is a text file containing a valid LSP program and arguments is a list of arguments:

localsolver file.lsp [arguments]

The arguments will be available in the LSP programs as global variables. Each argument consist in an assignment of a value to a global variable. Before starting the execution of the program, these assignment statements will be executed. They are described by the following lexical definition:

arguments      : argument*
argument       : identifier "=" value
value          : float | integer | string | cmdmap
cmdmap         : ( identifier ":" cmdmapvalue | cmdmapvalue )+
cmdmapvalue    : float | integer | string

For example:

localsolver test.lsp x=12 y=abc z="a string with whitespaces" t=true

will assign the integer value 12 to variable x, the string "abc" to variable y, the string "a string with whitespaces" to variable a and the value 1 to variable t.

The assignment of values to maps follows a specific syntax:

localsolver test.lsp a=z,12,8:text,key:41

will create a map a with z associated to key 0, 12 associated to key 1, text associated to key 8 and 41 associated to key key.

Note

The syntax a={2,3} is not valid to assign maps in the command line since unix shells interpret braces as a quantifier.

Note

On Windows, the colon character : is used to separate the drive letter from the directory. Thus, do not refer explicitely to the drive when you want to pass a path in a variable.

For example localsolver myFile.lsp inFileName=C:\\tests\\test.in will not assign the given path to the global variable inFileName. According to the explained behavior above, it will create a map with \tests\test.in assigned to key C.
