58 // ParmParse class implements a simple database for the storage and
59 // retrieval of command-line and input-file arguments. The entries are
60 // stored in a static table in (name,value_list) pairs.
61 //
62 // The format of the input file is a series of DEFINITIONS.
63 //
64 // A DEFINITION is of the form <name> = <value> <value> ...
65 // The equal sign is important since the list of values can span multiple
66 // lines.
67 //
68 // Comments in an input file include all text from a '#' character to the
69 // end of the line. Here is an example input file:
70 /*
71  niter = 100 # niter is an integer
72  title = "Double Wammy" # example of a string with spaces
73  cell_size = 0.5 0.75 # cell spacing in each dimension
74  plot.var = Density 1 10 # a list of values
75  plot.var = Energy 5 12 # another list of values
76  bigarray = 1 2 3 4 5 6 7 8 \
77  9 10 11 12 # continuation of bigarray
78  multi_line_string = "This is a
79  multi-line string."
80  test = apple "boy blue" 10 20 30 40
81  FILE = prob_file # insert contents of this "prob_file" here
82 */
83 // For values spanning multiple lines, one must use '\' at the end of a line
84 // for continuation, otherwise it's a runtime error. Note that there must be
85 // at least one space before the continuation character `\`. Multiple lines
86 // inside a pair of double quotes are considered a single string containing
87 // '\n's. The "FILE = <filename>" definition is special. Rather than just
88 // adding this entry to the database, it reads the contents of <filename>
89 // into the database.
90 // For CI/CD workflows and out-of-source tests, the environment variable
91 // AMREX_INPUTS_FILE_PREFIX can be set to prefix every FILE = <filename>
92 // with a custom path.
93 //
94 // ParmParse stores all entries in a static table which is built the
95 // first time a ParmParse object is constructed (usually in main()).
96 // Subsequent invocations have access to this table.
97 // A ParmParse constructor has an optional "prefix" argument that will
98 // limit the searches to only those entries of the table with this prefix
99 // in name. For example:
100 // ParmParse pp("plot");
101 // will find only those entries with name given by "plot.<string>".
102 //
103 // All values in the table are stored as strings. For example, the
104 // values of "cell_size" in the above input file are stored as the
105 // strings "0.5" and "0.75". These strings can be returned as either
106 // strings or numeric values by the query functions.
107 // Character strings with spaces must be delimited by double quotes
108 // in the input file but the quotes are stripped before they are entered
109 // into the table. For example, 'title' in the above input file has a
110 // single value, the string 'Double Wammy' (without the quotes).
111 // Each value in the list associated with a definition can be referred to
112 // by its index number. The index numbers start at 0 just like an array
113 // in the C programming language. Consider the definition of "test" in
114 // the above input file. The first value 'apple'is a string with index
115 // 0. The second value 'boy blue' is a string with index 1. The
116 // remaining four values are integers indexed 2, 3, 4, and 5.
117 //
118 // For a string value to represent an integer or float it must fit the
119 // following regular expression:
120 // Sign ::= '+' | '-'
121 // Digit ::= '0' | '1' | ... | '9'
122 // Integer ::= [Sign]Digit+
123 // Exp ::= ('e'|'E')Integer
124 // Float ::= ( Integer[.Digit*][Exp] | [Integer].Digit+[Exp] )
125 //
126 // Where '+' indicates one or more occurrences, '*' represents zero or
127 // more occurrences, '|' means one or the other and '[]' represents zero
128 // or one occurrence.
129 //
130 // Note that floats and doubles have the same string representation and
131 // that the FORTRAN "double" exponent format is not supported.
132 // That is, 1.0d+3 is not a valid representation of a floating point
133 // number but that 1.0e+3 is acceptable.
134 //
135 // There are a host of functions allowing the user to query the database
136 // and retrieve values. Here are some general rules about the names of
137 // the member functions:
138 //
139 // * Functions with the string "get" in their names attempt to get a
140 // value or an array of values from the table. They generate a
141 // run-time error if they are not successful.
142 //
143 // * Functions with the string "query" in their names attempt to get a
144 // value or an array of values from the table. They return the value 1
145 // (true) if they are successful and 0 (false) if not.
146 //
147 // * Functions with the string "kth" in their names get values from
148 // the Kth entry with the given name in the database. This is
149 // necessary since there may be multiple definitions with the same
150 // name in the database.
151 //
152 // * Functions without the string "kth" in their names get values from
153 // the last entry with the given name in the database. Note that the
154 // definitions from the command line are appended to the database table
155 // and hence will be the last entries.
156 //
157 // * Functions with the string "arr" in their names get an Array of
158 // values from the given entry in the table. The array argument is
159 // resized (if necessary) to hold all the values requested.
160 //
161 // * Functions without the string "arr" in their names get single
162 // values from the given entry in the table.
163 //
164 // The following is a code sample showing how to use ParmParse:
165 //
166 // main(int argc, char **argv)
167 // {
168 // char* in_file_name = argv[1];
169 // ParmParse::Initialize(argc-2, argv+2, in_file_name);
170 //
171 // // Query table for value of "niter". If not in table
172 // // then set to default value
173 // if (!pp.query("niter",niter)) niter = 20;
174 //
175 // // read array of cell sizes if in table
176 // Vector<float> dx;
177 // if (nx=pp.countval("cell_size")) {
178 // // get nx values starting at index 0 and store in dx.
179 // // dx is automatically resized here.
180 // pp.getarr("cell_size",dx,0,nx);
181 // }
182 // ParmParse::Finalize();
183 // }
184 //
185 // void do_graphics()
186 // {
187 // //
188 // // Will only query entries with the "plot" prefix:
189 // //
190 // ParmParse pp("plot");
191 // //
192 // // Read all variables with "plot.var" keyword.
193 // //
194 // std::string var_name;
195 // Vector<int> range;
196 // int num = pp.countname("var");
197 // for (int k = 0; k < num; k++)
198 // {
199 // //
200 // // Element 0 in list is a string.
201 // //
202 // pp.getkth("var",k,var_name,0);
203 // //
204 // // Elements 1 and 2 are integers.
205 // // Note that "range" will be resized to hold 2 elements.
206 // //
207 // pp.getktharr("var",k,range,1,2);
