Detailed Description

Parse Parameters From Command Line and Input Files.

The ParmParse class is used to interpret parameters passed in to a program from the command line and an arbitrary collection of input files. The parameters are stored in static table that can be queried by any object of type ParmParse. A parameter can be either an "option" (usually specified on the command line) or a "definition". An option is of the form "-<name>" and is stored in the table without the hyphen. A definition is of the form "<name> = <value><value>...<value>". It is stored in the table as a name, value-list pair.

In the following example, verbose and no_opt are stored in the table as options. niter is a definition with the single integer value 10; name is a definition with the string value "big code" and dx is a definition with the two floating point values 0.5 and 0.75.

prog -verbose -no_opt niter = 10 name = "big code" dx = 0.5 0.75

The ParmParse class has two constructors. The first is responsible for building the table and is usually called by the main routine of an application. It has arguments for the command line argc and argv parameters, as well as an optional filename argument for reading definitions from an input file. The table is built by reading the input file first (if it exists) with the command line arguments added to the end of the table. The order of a definition in the table is significant, so command line parameters can be used to override definitions in the input file. A definition of the explicit form: FILE=<filename> is not added to the table but is a directive to include the named file at that point in the table.

The second constructor is generally used by other classes in the code. It permits access to the table via a large collection of query functions. Both constructors have an optional prefix argument that narrows the search to entries in the table with the same prefix. For example, let PlanR be a ParmParse object with code prefix "ope". PlanR.get("val",v) will look for an entry in the parameter list of the form: ope.val==<value>, and will reject all entries not starting with the correct code prefix.

The query functions search the table for definition names that match a given string (and prefix) and return values from the corresponding value list. The values can be returned as ints, Array<int>s, floats, std::vector<float>s, doubles, std::vector<double>s, std::strings, or std::vector<std::sring>s. All values in the table are stored as PP_String objects, but if an int, float, or double is requested, the translation is done automatically. In the previous example, the value of niter could be returned as either an std::string, an int, a double, or a float. The values of dx can be returned as std::strings, floats, or doubles, but the value of name can be returned only as an std::string.

Comments in an input file include all text from a `#' character to the end of the line. Here is a sample input file:

-no_garbage

niter = 100

title = "Double Wammy"

cell_size = 0.5 0.75

plot.var = Density 1 10

plot.var = Energy 5 12

bigarray = 1 2 3 4 5 6 7 8

9 10 11 12

test = apple "boy blue" 10 20 30 40

FILE = prob_file

Constructor & Destructor Documentation

ParmParse::ParmParse (  int  argc,
char **  argv,
const char *  prefix = 0,
const char *  parfile = 0
) 
 

Construct an initial ParmParse object from the argc and argv passed in to main(). An error will be signalled if another ParmParse object currently exists. If parfile is specified, read the parameters in from that file first and then append those derived from argv to the table. If prefix is specified, load this string as the code prefix for this particular ParmParse object.

ParmParse::ParmParse (  const char *  prefix = 0  ) 
 

Construct an additional ParmParse object sharing the same internal table as any other such objects in existence. If prefix is specified, load this string as the code prefix for this particular ParmParse object.

ParmParse::~ParmParse (   ) 
 

The destructor. The internal static table will only be deleted if there are no other ParmParse objects in existence.

int  num_val
) 
 

Gets a std::vector<bool> of num_val values from last occurrence of given name. If successful, the values are converted to a bool and stored in the std::vector<bool> object ref. ref is resized (if necessary) to hold num_val values. The value in the list indexed by start_ix is copied into std::vector<bool>[0], std::vector<bool>[1] holds start_ix+1, etc. Returns 0 if the name does not exist. If there are fewer than start_ix + num_val values associated with the last occurrence, or if some of the values cannot be converted to a bool, an error message is reported and the program halts.
