fpp to layout

This tool writes layout text files for connection graphs within F Prime topologies.

Options:

1. -d dir: Set the output directory to dir. If this option is not present, then the output directory is the current directory.

2. -i files: Import files. The definitions in these files are part of the FPP model, but they do not cause any code to be generated.

Input:

1. A list fl_tr of files to translate: either the single file stdin or a list of files specified on the command line.

2. A list fl_i of files to import, specified as arguments to the -i option.

Output:

1. A set of .txt files, written to a topology layout directory (name format: <TopologyName>Layout) at the directory specified with the -d option (if present).

Procedure:

1. Parse each of the files in fl_tr, generating a list tul_tr of translation units. When parsing, recursively resolve include specifiers.

2. Do the same for fl_i, generating a list tul_i.

3. Perform semantic checking on the concatenation of tul_fl and tul_i.

4. Check that no two definitions in tul_tr will generate a directory with the same name. If so, halt with an error message.

5. For each topology definition T in tul_tr:

   1. Check to see if a directory already exists for the topology. If a directory already exists, delete the directory and re-create it.

   2. Generate the layout text output (according to FPL Input Format) of each connection graph in the topology.

   3. Write layout text files to the topology directory.
