- ### Start of ProcArgs library
- # @(#) ProcArgs 1.10 96/11/16
- # 92/02/29 john h. dubois iii (john@armory.com)
- # 93/07/18 Added "#" arg type
- # 93/09/26 Do not count -h against MinArgs
- # 94/01/01 Stop scanning at first non-option arg. Added ">" option type.
- # Removed meaning of "+" or "-" by itself.
- # 94/03/08 Added & option and *()< option types.
- # 94/04/02 Added NoRCopt to Opts()
- # 94/06/11 Mark numeric variables as such.
- # 94/07/08 Opts(): Do not require any args if h option is given.
- # 94/09/23 Fixed bug that caused fail if -opt<value> given as last arg.
- # 95/01/22 Record options given more than once. Record option num in argv.
- # 95/06/08 Added ExclusiveOptions().
- # 96/01/20 Let rcfiles be a colon-separated list of filenames.
- # Expand $VARNAME at the start of its filenames.
- # Let varname=0 and -option- turn off an option.
- # 96/05/05 Changed meaning of 7th arg to Opts; now can specify exactly how many
- # of the vars should be searched for in the environment.
- # Check for duplicate rcfiles.
- # 96/05/13 Return more specific error values. Note: ProcArgs() and InitOpts()
- # now return various negatives values on error, not just -1, and
- # Opts() may set Err to various positive values, not just 1.
- # Added AllowUnrecOpt.
- # 96/05/23 Check type given for & option
- # 96/06/15 Re-port to awk
- # 96/10/01 Moved file-reading code into ReadConfFile(), so that it can be
- # used by other functions.
- # 96/10/15 Added OptChars
- # 96/11/01 Added exOpts arg to Opts()
- # 96/11/16 Added ; type
-
- # optlist is a string which contains all of the possible command line options.
- # A character followed by certain characters indicates that the option takes
- # an argument, with type as follows:
- # : String argument
- # ; Non-empty string argument
- # * Floating point argument
- # ( Non-negative floating point argument
- # ) Positive floating point argument
- # # Integer argument
- # < Non-negative integer argument
- # > Positive integer argument
- # The only difference the type of argument makes is in the runtime argument
- # error checking that is done.
-
- # The & option is a special case used to get numeric options without the
- # user having to give an option character. It is shorthand for [-+.0-9].
- # If & is included in optlist and an option string that begins with one of
- # these characters is seen, the value given to "&" will include the first
- # char of the option. & must be followed by a type character other than ":"
- # or ";".
- # Note that if e.g. &> is given, an option of -.5 will produce an error.
-
- # Strings in argv[] which begin with "-" or "+" are taken to be
- # strings of options, except that a string which consists solely of "-"
- # or "+" is taken to be a non-option string; like other non-option strings,
- # it stops the scanning of argv and is left in argv[].
- # An argument of "--" or "++" also stops the scanning of argv[] but is removed.
- # If an option takes an argument, the argument may either immediately
- # follow it or be given separately.
- # "-" and "+" options are treated the same. "+" is allowed because most awks
- # take any -options to be arguments to themselves. gawk 2.15 was enhanced to
- # stop scanning when it encounters an unrecognized option, though until 2.15.5
- # this feature had a bug that caused problems in some cases. See the OptChars
- # parameter to explicitly set the option-specifier characters.
-
- # If an option that does not take an argument is given,
- # an index with its name is created in Options and its value is set to the
- # number of times it occurs in argv[].
-
- # If an option that does take an argument is given, an index with its name is
- # created in Options and its value is set to the value of the argument given
- # for it, and Options[option-name,"count"] is (initially) set to the 1.
- # If an option that takes an argument is given more than once,
- # Options[option-name,"count"] is incremented, and the value is assigned to
- # the index (option-name,instance) where instance is 2 for the second occurance
- # of the option, etc.
- # In other words, the first time an option with a value is encountered, the
- # value is assigned to an index consisting only of its name; for any further
- # occurances of the option, the value index has an extra (count) dimension.
-
- # The sequence number for each option found in argv[] is stored in
- # Options[option-name,"num",instance], where instance is 1 for the first
- # occurance of the option, etc. The sequence number starts at 1 and is
- # incremented for each option, both those that have a value and those that
- # do not. Options set from a config file have a value of 0 assigned to this.
-
- # Options and their arguments are deleted from argv.
- # Note that this means that there may be gaps left in the indices of argv[].
- # If compress is nonzero, argv[] is packed by moving its elements so that
- # they have contiguous integer indices starting with 0.
- # Option processing will stop with the first unrecognized option, just as
- # though -- was given except that unlike -- the unrecognized option will not be
- # removed from ARGV[]. Normally, an error value is returned in this case.
- # If AllowUnrecOpt is true, it is not an error for an unrecognized option to
- # be found, so the number of remaining arguments is returned instead.
- # If OptChars is not a null string, it is the set of characters that indicate
- # that an argument is an option string if the string begins with one of the
- # characters. A string consisting solely of two of the same option-indicator
- # characters stops the scanning of argv[]. The default is "-+".
- # argv[0] is not examined.
- # The number of arguments left in argc is returned.
- # If an error occurs, the global string OptErr is set to an error message
- # and a negative value is returned.
- # Current error values:
- # -1: option that required an argument did not get it.
- # -2: argument of incorrect type supplied for an option.
- # -3: unrecognized (invalid) option.

- # Data[] is a tree of data to draw. The indexes consist of one or more
- # integer values separated by SUBSEP. The "depth" of the element determines
- # how many integers (dimensions) are contained in the index. For each set
- # of node siblings, the integer describing the varying dimension varies from
- # 1 through n where n is the number of siblings. This shows the indexes
- # used for the elements of a small tree with depth 3:
- # 1----+-1,1--+-1,1,1
- # | |-1,2,2
- # | \-1,2,3
- # \-1,2--+-1,2,1
- # \-1,2,2
- # 2------2,1--+-2,1,1
- # \-2,2,2
- # ^----^--see below
- # The values of the elements are lines of data which constitute the
- # nodes of the tree.
- # By default, the tree is drawn with each node on a separate line.
- # Offset is the horizonal offset of each child from its parent. It must be
- # at least 1. If Width is non-0, the tree is drawn with the first child of
- # each parent immediately to the right of its parent. Width is the number
- # of characters allocated to the node data for each level. If the data for
- # an interior node is longer than Width, the value is truncated to Width-1
- # characters and a left-tee is appended to indicate the truncation, so Width
- # should be at least two. If this style is used, Offset is the number of
- # characters of additional horizontal separation to use after the "split
- # point"; in the example tree above, Width is set to 1, causing the addition
- # of the characters at the positions marked by ^ on the "see below" line.
- # The tree is drawn using box-drawing characters appropriate to the
- # terminal if they are available, and a default set of ASCII characters if
- # not.
- # If AltChars[] contains all of the following elements, they are used to draw
- # the tree. I is the index to use; A is the ASCII default.
- # I A Description
- # x | Vertical bar
- # q - Horizontal bar
- # m \ bottom left corner
- # w + Top tee
- # t } Left tee
- # + > Right arrow (optional)
- # ~ * Bullet (optional)
- # If AltChars[] does not contain all of these elements and the alternate
- # character set it used, AltChars[] is returned filled in with the
- # characters used to draw the tree. The same array can then be passed back
- # to DrawTrees(), avoiding the need for it to use tput again to get the
- # terminal's alternate character set capabilities.
- # If Spaces is true, indentation is done with spaces only; the effect is to
- # set all of the above characters to be a space.
- # If term is passed, it overrides the TERM environment variable. Pass "dumb"
- # to force the ASCII values to be used.
- # If the terminal has a right-arrow character defined and useArrow is true,
- # it is used for the branch character to the left of node data.
