74 # header_gen_rv_test_inc.pl : tool to generate header files
75 #
76 # Short spec:
77 #
78 # This tool generates one header file using the information from the command
79 # line. The expected fommand line form is:
80 #
81 # header-file-name other-parameters
82 #
83 # where header-file-name is the filename of the include file to be generated
84 # (including path components).
85 # other-parameters parameters define an association of names to values. each
86 # association has the form:
87 #
88 # name=value
89 #
90 # name may have an prefix SWE_, which is then ignored. name must have the
91 # suffix _STATE, otherwise this particular association is ignored.
92 # only the component between SWE_ and _STATE gets considered. value must
93 # be 2, otherwise this particular association is ignored.
94 #
95 # The tool generates from the accepted (not ignored) a list of defines.
96 # the identifiers are the considered part of the other-parameters, but have
97 # the prefix TEST_ and suffix _SWE. The values they define start with 1,
98 # increasing.
99 # the order of the parameters is not important. However, it must be the same
100 # as of the tool header_gen_rv_test_exec_level.pl (see there).
101 # Conveniently both tools should be invoked with the same other-parameters.

147 #
148 # the contents of the header file will be of the ANSI C language.
149 # it is a the definition of an array:
150 # static char TEST_LEVEL_LCD [TEST_LEVEL_LCD_LEN][TEST_LEVEL_LCD_STR_LEN] =
151 # having 0-terminated strings as components.
152 # the values of TEST_LEVEL_LCD_LEN and TEST_LEVEL_LCD_STR_LEN and the elements
153 # of the array depend on the parameters:
154 # TEST_LEVEL_LCD_LEN is the number of considered (or not ignored)
155 # other-parameters PLUS 1.
156 # TEST_LEVEL_LCD_STR_LEN is the length of the strings. various rules apply,
157 # e.g. for 0 termination (but at last, it will get the value of 15!).
158 # see below and/or ask a ANSI C guru.
159 # the strings have the form: running index," - ", considered name component
160 # (max 8 chars), filling blanks (up to the final length)
161 # the running index use 3 characters, i.e. no more than 999 considered indexes
162 # are allowed. this is no problem for the time being.
163 # Thus we can compute the max length: 3+3+8+1=15 (running index, delimiter,
164 # name, string delimiter \0).
165 # There is one special initial string. it is always placed at index 0 and has
166 # the contents " TEST LEVEL " plus '\0'.
167 # the 2 spaces at the beginning are legacy, I guess they are just to have a
168 # left alignment with the first 9 indexes (those with 1 figure indexes)
