Library Reference

Note: the LMNtal API is under development and its specification is subject to change.

In the following, arguments with the '+' sign are those consumed upon reaction with the library atoms, while arguments with the '-' sign are those generated by the library API. The slash (/) notation is used to indicate the arity of atoms.

Library nlmem

The library nlmem (nonlinear membrane) contains an implementation of the following rule schemes that use aggregates:

R=nlmem.copy(X,a), {$p[X|*Z]} :-
   R=copied(X1,X2),
   {$p[X1|*Z1]}, {$p[X2|*Z2]},
   a(*Z1,*Z2,*Z).
nlmem.kill(X,b), {$p[X|*Z]} :- b(*Z).

They are rule schemes in the sense that a and b are metasymbols to be replaced by any symbolic names.

nlmem.copy(+{P},+a,-R)
An abbreviated form of (nlmem.copy(R0,a,R), {+R0,P}). Creates two copies of the cell {+R0,P} with all its free links renamed, and connects R and the two fresh copies of R0 using a ternary atom with the name a. Furthermore, for each free link L of the original cell {+R0, P} (except R0 that will disappear together with the '+'), nlmem.copy connects the two fresh copies of L and the original L via the ternary atom a.
nlmem.copy(+{P},-R)
Same as {nlmem.copy({P},copied,R).
nlmem.kill(+{P},+b)
An abbreviated form of (nlmem.kill(R0,b), {+R0,P}). Connects each free link L of the cell {+R0, P} (except R0 that will disappear together with the '+') to the unary atom b.
nlmem.kill(+{P})
Same as nlmem.kill({P},killed).

Library io (SLIM)

Input/output in SLIM is done through ports. An operation on a port will return a new port to be used for future operations on the port.

io.stdin(-RetRort)
Returns a standard input port.
io.stdout(-RetRort)
Returns a standard output port.
io.read_line(+Port,-RetRort,-Str)
Read a single line Str from the input port Port and returns a new port RetRort.
io.read_char(+Port,-RetRort,-C)
Read a character C from the input port Port and returns a new port RetRort.
io.read_token(+Port,-RetRort,-S)
Read a token S separated by a space or newline from the input port Port and returns a new port RetRort.
io.close_port(+Port,-RetRort)
Close Port and returns it as RetRort. Further operations on the port will cause an error.
io.free_port(+Port)
Frees Port.
io.print_char(+Port,+C,-RetRort)
Print a character C or an atom name C to Port and return a new port RetRort.
io.print(+Port,+Str,-RetRort)
Print a string Str to Port and return a new port RetRort.
io.print_newline(+Port,-RetRort)
Print a newline to Port and return a new port RetRort.
io.print_line(+Port,+Str,-RetRort)
Print a string Str and a newline to Port and return a new port RetRort.
io.print_mem(+Port,+M,-RetRort)
Print the content of the membrane M to Port and return a new port RetRort.
io.open_output_string(-SRetRort)
Creates a new string output port SRetRort.
io.open_input_string(+Str,-SRetRort)
Creates a new string input port SRetRort consisting of the characters in the string Str.
io.output_string(+Port,-RetRort,-Str)
Dumps the current content of the string port Port to Str and returns the port as RetRort (without flushing it).
