- ARexxBox - ARexx Interface Design Tool
- FREEWARE, (C) 1992 Michael Balzer
-
- ARexxBox (inspired by the GadToolsBox) is a tool for designing
- ARexx interfaces for your programs, with the special goal to
- greatly simplify this procedure while coming as close as possible
- to the suggestions and ideas stated in the User Interface Style
- Guide's ARexx section.
-
- ARexxBox is for ARexx, what GadToolsBox is for the GUI.
-
- FEATURES:
-
- - Syntax and results of the ARexx commands follow
- exactly the conventions suggested by the Style Guide,
- e.g. command arguments are parsed using the AmigaDOS
- ReadArgs function, and the keywords VAR and STEM are
- supported automatically.
-
- - Each command may have an unlimited number of arguments
- and results.
-
- - All ReadArgs template options are allowed for arguments
- and are supported automatically. For results, the
- switches /N and /M are supported.
-
- - Graphical user interface (designed using GadToolsBox :-).
-
- - Generates ANSI C or Oberon-2 source.
-
- - ARexxBox can generate source for CommandShells, shells
- in which the user may enter ARexx commands directly
- and view their output.
-
- - CommandShells can be used to execute external macros.
-
- - A program may open as many ARexx ports and
- CommandShells as the system memory will allow.
-
- - ARexx commands can use an extended error return feature
- using a secondary return code.
-
- - I already entered all standard commands suggested by
- the Style Guide. Example code for some of them is also
- included.
-
- REQUIREMENTS:
-
- ARexxBox and the generated code will only run on AmigaOS 2.04
- (or better). The Box (but not the generated source) needs
- reqtools.library by Nico Francois.
-
- HISTORY SINCE LAST RELEASE:
-
- V1.12
- FIXED: The HELP command produced Enforcer hits (strlen(0)).
- (Report: Klaas Hermanns)
-
- ENHANCED: Introduced tag #2 for commands: External status flag,
- "New" state of this flag will only be reset by external programs,
- e.g. documentation aids like ARB2TeXinfo by Albert Weinert.
- (Suggestion: Albert Weinert)
-
- FIXED: The command list was generated not alphabetically but
- numerically sorted (by their IDs).
- (Report: Klaas Hermanns)
-
- ENHANCED: Instead of the binary search algorithm, the Box now
- generates a real finite state machine for searching of commands
- (FindRXCommand). The binary search method had a big design flaw
- with abbreviations on the alphabetically sorted list of commands.
- (ATT: This has been implemented for C only up to now!)
- (Report: Klaas Hermanns)
-
- FIXED: For SAS C, toupper() will be #undefined. Also there is now
- the real function cast in the list of commands.
- (Report: Klaas Hermanns)
-
- FIXED: The MIN and MAX results of Misc.arb/GETATTR have to be
- numbers, of course.
- (Report: Klaas Hermanns)
-
- FIXED: "Merge" trashed the command list when merging in existing
- commands.
-
- CHANGED: Now declares the external library bases with their
- appropriate types (C).
- (Wunsch: Klaas Hermanns)
-
- CHANGED: In arb/advanced.arb, commands REQUESTNUMBER and
- REQUESTSTRING, I changed the argument called "DEFAULT" to "DEFAULTNUM"
- resp. "DEFAULTSTR" to avoid conflicts with the 'default' keyword in C.
- (Report: Klaas Hermanns)
-
- ENHANCED: There's now another parameter for all interface functions
- called "struct RexxMsg *rexxmsg", which will contain the address of
- the message from REXX if called by ARexx. If called from a command
- shell, it will contain NULL, so you can also use it to determine the
- caller. This is to support GetRexxVar(), which needs this pointer.
- (Report: Klaas Hermanns)
-
- FIXED: I now define toupper() as a function for GCC. The macro caused
- problems by evaluating the parameter more than once.
-
- FIXED: The command shell parameter parsing had a bug (the ReadArgs
- buffer wasn't cleared).
