- From Howard's text file:
-
- Challenge: Use OS/2 to build a farily powerful gopher client program
- with the least amount of code.
-
- Gopher is a protocol for organizing distributed information. The user
- is presented with a view of folders containing other folders, documents,
- terminal sessions, and simple query servers. In reality, information is
- retrieved using the TCP/IP network and a very simple protocol.
-
- OS/2 2.0 provides an ideal environment for a gopher client. Its
- "Workplace Shell" consists of folders containing other folders and
- objects. If an object is a file it can be opened and displayed. Other
- objects are programs which when run can prompt for input.
-
- Unfortunately, it requires some heavy duty C programming to create new
- object classes. More importantly, trying to model gopher objects as
- "folders" and "files" interacts with the disk directories in an
- unclear manner, while basing them on "programs" would produce poor
- performance and a lot of I/O to the system object database.
-
- So do something simple first, and get fancy later on. VREXX is a
- package written by an IBM employee and posted on various OS/2 file
- sources (ftp-os2.nmsu.edu and software.watson.ibm.com). It allows
- REXto display simple dialog boxes and windows. With a
- small C program to do the gopher protocol, the supplied REXX program,
- and
-
- IBM TCP/IP for OS/2 1.2.1
- OS/2 2.0
-
- this code provides a gopher client with a lot of function for
- very little effort. It is not object oriented, but it can
- compete with character based gopher clients.
-
- What is very nice about this platform is that you can hack
- new features easily. REXX is very simple and powerful. The REXX
- program runs in its own character mode window where you can trace
- and single step new code.
-
- This is neither the final word nor a product. The objective is to
- get the ball rolling and interest others in doing some hacking.
- The source to rodent.c is provided, but recompiling it requires some
- hacked versions of the \TCPIP\INCLUDE\*.h files which are tough to
- distribute without violating IBM copyright. You are free to
- 1) use the enclosed EXE
- 2) recompile with MS C 6.00 and build a 16 bit version
- 3) rewrite from scratch with your own favorite tool
- but don't write me asking for the *.h files.
