•Abstract

GopherApp is an Internet information service program for
Macintosh computers.  It provides a Finder-like link to the range
of Internet Gopher services.

GopherApp is being written by Don Gilbert, using the MacApp
extensible Macintosh programming framework from Apple Computer.
It is actually a subset of a biosequence analysis program
called SeqApp.

To use GopherApp, your Mac must have a network connection to the
Internet, and it must have MacTCP installed and operating (as
with NCSA Telnet, Eudora, network news and similar MacTCP-based
Internet programs).   You can also use GopherApp over telephone lines
when MacTCP has a SLIP interface and you dial-up to a Serial Line IP
server.

You may obtain GopherApp thru anonymous ftp to ftp.bio.indiana.edu, in
folder /util/gopher, as gopherapp.hqx. You may also obtain updates
using Gopher to this same IUBio archive (host=ftp.bio.indiana.edu,
port=70). Look for a folder called "IUBio Software+Data/GopherApp".

GopherApp.Help is a plain text file which may be read from your favorite
wordprocessor.  If you have problems getting  GopherApp to launch,
please read GopherApp.Help.  GopherApp works on all Mac models from
Mac+, with System 7 and System 6 software.

Programmers with MPW Pascal and C and MacApp 2.x libraries may
obtain source for GopherApp as "gopherapp-src.hqx" next to the
GopherApp application above.

 *****************************************************

This program is being written by Don Gilbert.
I don't expect it to mature for another 6 to 12 months,
as my prime programming time is holidays and weekends.

This GopherApp program is copyrighted 1992 by D.G. Gilbert. All
rights are reserved.  You may use GopherApp for non-commercial
tasks, and you may re-distribute it, if you make *no* charge
for the redistribution and if you include the full, unmodified
distribution set (you may add features).

It is written with MPW Object Pascal & some C using the MacApp
extensible Macintosh programming framework from Apple Computer,
which copyrights the MacApp portion.

As of release 1.1b, the full source code (excluding MacApp
libraries), is available for non-commercial uses.  Modified
versions may be distributed as long as information regarding
the original distribution is included.  Look for the file
gopherapp-src.hqx for the source in the same location (above)
as the application.

•Installing

If you obtain this release thru FTP file transfer, you have
a binhex encoded archive file.  You will need the Stuffit
(version 1.5?) or Unstuffit applications.  The former includes
an un-binhex option to convert from text encoding
to macbinary Stuffit archive.  These are widely available from
Mac software archives, user groups, and computing support people.
Use Stuffit to extract the distribution folder.


•Data files

GopherApp uses files of type 'IGo4' which are actually Text but in the
strict format used in the Gopher transaction protocol:

[Type Char][Title....]<tab>[Path]<tab>[Host.address]<tab>[Port#]<cr>

This is repeated for any number of lines.  These files *can* be converted
to text, editted, then reconverted to Gopher files, if you know what
you are doing.  Later there may be a feature to edit this info in
the Gopher windows.

The New and Open commands on the File menu will let you create new
or open old Gopher files.  You should use Copy/Paste and dragging gopher
items, as well as the "New gopher link" and "Edit gopher link" commands
to create gopher document files that suit your tastes.

You may also edit a gopher document file as if it were a TEXT file (Open
as Text).  When you save such a file, it is saved as a TEXT type.  You
can convert it back to a GopherApp document by using the "Gopher..." command
from the Internet menu, while holding down the OPTION key.  Open the
document then resave it as a Gopher type (IGo4).  The prefered way to
edit gopher links is with "Edit gopher link" command however.

A really sneaking option (I was out of User Interface hacking time) is
to SAVE AS with OPTION key down.  This creates a document in the style of
Gopher Server link files:
    Name=bob
    Type=0
    Path=....
However, GopherApp cannot (yet) re-read these.  You need to convert to TEXT
and move to your Unix server.


•Features

••File

New and Open will create new or open old Gopher folder files.  New Text and and Open
Text work on plain text, which is the format of the Gopher data files also.

Save, Save as, Save a copy in, all will save the current document to disk files.
Revert will restore the open align view to the last version saved to disk.

Print setup, print will print the current view.

Help brings up a view to page thru the help file.

••Editing

Undo, cut, copy, paste, clear, select all -- these standard mac commands
will operate on text as well as on Gopher items in (hopefully) intuitive,
usual ways.

Find, Find same, Find "selection" will search for strings in text.

Replace, replace same will replace target strings (not yet enabled).


••Text styling

In most of the edittable text windows you can specify text styles, fonts,
sizes. These styles are not currently saved (bug).

••Internet

The Internet features of GopherApp let you interchange ideas and data with
people and computing services around the world.  If your Mac is connected
already to the Internet, you probably are familiar with electronic mail and
some of its uses.

GopherApp includes a selection of network access features in the
including (if it isn't bombing like it was yesterday:) a feature to send
and receive e-mail.


•••Internet requirements

All features of this menu depend on (a) a network link to the Internet, and (b)
MacTCP software developed by Apple Computer.  The network link may be thru
Appletalk or thru Ethernet.  MacTCP is not (yet) part of Macintosh System software.
It may be purchased in individual copies or site licenses, and it is common
for a university or research institution to have a site license.  It also is
packages with various commercial applications.

GopherApp is now SLIP-aware.  It will work properly over a telephone/modem
connection to a Serial Line Internet Protocol (SLIP) server, if you have
proper SLIP software to use with MacTCP.  This includes Versaterm's SLIP
link (by Lonnie Abelbeck, sold thru Synergy Software), MacSLIP and perhaps
others later. I find that GopherApp is useable even at 2400 baud, though I
don't recommend that slow a speed for browsing lengthy documents.  See the
Gopher Prefs dialog to set a long TCP timeout for SLIP.

•••Mail Preferences

The mail prefs dialog asks for your return e-mail address, your preferred
SMTP mail host, and your POP mail address and password.  These addresses
may be similar.

Return e-mail address:  This is where another person should send mail so it
will reach you.
        Example:  [e-mail]
               or:  [e-mail]

SMTP Mail host:  This is the internet address of the computer thru which
SeqApp will send out mail to the rest of the world.
        Example:  Sunflower.Bio.Indiana.Edu

POP Mail address: Not supported (yet) in GopherApp.
The POP mail address is not required to send mail.

•••Send Mail

Send an electronic mail message.  You must enter an address to send to, and
have entered your return address in the mail preferences dialog.

•••Read Mail

This will retrieve electronic mail from a Post Office Protocol (POP)
server computer.  You also need a POP server computer with proper software and
a mail account.  The standard POP server software for Unix computers is available via
anonymous ftp to ftp.CC.Berkeley.Edu (128.32.136.9), as pub/popper-xxx.tar.Z.
I also highly recommend Eudora as a Mac client for reading POP mail.  Get this by
anonymous ftp to ftp.cso.uiuc.edu, in the mac/eudora subdirectory.

•Gopher

Internet Gopher gives you access to a wide range of information services
that are now developing on the Internet.  Gopher is something
like Telnet or FTP (file transfer), but also different.  It includes some
of the keyword searching features of WAIS (Wide Area Information Services).
There are currently several biology gopher services found around the globe.
These include fast and up-to-date keyword searches of GenBank, EMBL, PIR
and other important biology databanks.

Gopher works something like the Macintosh Finder, only over the Internet
and with various restrictions -- basically you cannot yet PUT information
to remote servers, just GET it from them.  There are several file "types",
include Text documents, Folders with more items, Search items to search
databases for keyword matches, Phone book items to look up people's
addresses, Binhex encoded Mac programs that you can fetch, and others.

When you find folders in a Gopher window, you can double-click them to
open a new window with more items.  There is a drop-down menu at the
top of each gopher window which you can use like the (command-key) drop
down menu in Mac Finder windows, to select parent windows.

                                                   NOTE
Network status information is displayed in the top line of the current
Gopher window.  If a network connection seems to be frozen, or if a
file you are fetching seems too big, you can frequently halt the
transfer with a COMMAND-PERIOD keypress combination, as is standard
for other Mac applications.


••Gopher bugs

                                                   NOTE NOTE NOTE

As there are still some bugs in GopherApp which cause it to freeze or bomb,
if you are using Mac System 7, you can exit a frozen GopherApp without
restarting your Mac:
                                            Command-Option-Escape

keypress will always abort the front application.  Sometimes if you do this,
the MacTCP system software may be left in a bad state, and you may need to
restart your computer anyway (after safely closing other apps) in order
to re-use MacTCP programs.

CSO phonebook works at simple level.  GopherApp doesn't query CSO
server for valid fields as it should, so listed fields may fail. Some
queries may fail do to improper formatting (I'm no CSO expert).

I've added WHOIS phonebook type "w" since it is just a child object of
TextGopher + Search question. You can find a list of world wide WHOIS
servers at the IUBIO gopher, along w/ CSO servers.

The WAIS search seems to work for the shorter searches.  Known bug that
will be fixed when I get time is that search paths > 255 chars fail due
to use of Pascal string[255] for path storage.  I still wonder how/why
the WAIS directory on gopher.micro.umn.edu has those extra "0" directory
entries that caused GOpherApp to hang for a while.

I tried to implement a window-saving feature to have new gopher folder items
replace the current parent gopher folder, as per the Hypercard client.
This hasn't yet worked, for reasons I don't yet understand, but may in the
future.  The drop-down menus may some bugs yet -- I had to chase several
large entomological nighmares out of this.

In System 7, the Telnet sessions should be automatically launched.
I know the code I need to write & rewrite for this, but it will
take me a day, which I don't have just now.

>>> Bug reports from field, problems fixed (as of 26may92):

1) The types of a saved session (IGo4) and the app (SApp)
   are not the same as the predifined (IGo4/IGo4) [fixed]

2) When I cancel a TCP open, I still get a new window with
   the defaults from the resource IGo4. [should be fixed]
     This also happens when I open a empty folder. [feature]

5) I know its hard but it would be useful to run another app
   during data-transfer, and to put GopherApp in the background.
     [partial fix -- first background click may work, switch back
         to gopherapp then locks it -- needs mucho time to squash bug]

One problem I noticed is that when I first started the app it chose a
non-text font for the icon titles, which confused me at first.
[fixed as of 26may92, also added user pref for text view font]

---
A problem that I have is that when I click on an item
it will go out .. get the info. and the cms server will close the connection
however.. gopher app just sits there until I press  command .
it will then display the info.
[ protocol I used at first waited for ".<CR><LF>" terminator signal.
  Now, I think, TCP reading routines also notice when door
    has been slammed shut :) ]



>>> Bug reports from field, problems still pending:

1) Can you indicate how difficult (how long time) it would
   take to make a ISO-version? [maybe later]

3) Some of the items in Gopher Prefs (small icons) are greyed
   out (not implemented yet?) [not yet working]

4) How about to grey the folder that is open, like in Finder.
   Maybe you could close the old window if the option key
   were down (like in finder) [maybe later]

6) The clock, it doesn't rotate while TCP is working...
    [probably later]

----

Also, while composing this message, I had a minor problem with the last
line getting cut off, probably because the view was just slightly short.
[sendmail window should scroll, needs tweaking]

---
A small comment on GopherApp. If you open a config file in
text mode, add a new gopher and save it, it becomes a TEXT
file and Open... doesn't seem to work properly. It should
preserve the IGo4 file type.
[common complaint -- avoid using text mode to edit gopher
 documents (at least for now).  Changing file type to TEXT
 is Feature not Bug :) ]

I can't seem to get GopherApp to work with a Gopher server
running on the same Mac. I am using the Gopher Mac server
and have no problems with the Gopher client hypercard
stack. But GopherApp hangs at "TCP is waiting to open".
[no idea where problem is... later]

---
Whenever I double click on a goper server that does not
respond, (I suspect that it is off line)...the program
hangs with a clock face at the message TCP established.  I
have to reboot tht system to get out of this hang.  Command
period would be a nice interrupt here.
[I don't know if this is fixed or not.  The problem sometimes
is not a "hang" but a long timeout waiting for server.  I
need to put in user-choice of timeout length.  When using
System 7, remember that "Command-Option-Escape" key will
always abort front application, preventing need to reboot.]

---

...GopherApp seemed a bit slow when transferring large files.
[optimization will follow bug fixes (maybe)]

--
... get dialog/alert "Could not start the application because of
a program error". Disabling the TOPS 3.0 INIT sees GopherApp load OK.
... the only other MacTCP application I've had a
problem with is WAIS but I didn't try localizing the problem in that case.

[gopherapp and TOPS don't get along, reason unknown]

---
...trying to save files, and every
time I tried to, GopherApp gave a "disk error". It didn't matter
what disk, it just gave a disk error. Switching to the hypercard
FTP allowed me to save the files.
[Anyone else seeing disk errors trying to save GopherApp files?
This is not a general problem (I hope).  Any insight into particular
configuration needed to duplicate this problem will help me solve
it.]

---

We were wondering if there was a way to redirect the App to our server.

[This regards the default servers listed in a New document.  You need
to use Resedit to change the "IGo4" resources in Gopherapp.  The first one,
ID 0 "Bundle Stuff" must remain as is.  The other ones can be deleted, replaced
or edited.  The easiest way to put a new "IGo4" link into this resource is to
(a) Run GopherApp, open gopher doc w/ link, Select and COPY the link.
(b) Quit GopherApp, open it from ResEdit, open "IGo4" apps, create new IGo4 item
then PASTE the (text) of the link into the Ascii side of the IGo4 edit box.
]
---

I  don't have access to a DNS ... need to use Hosts file.

[Code is further along in using this.  I still need to put in nasty
Mac file name/directory/volume mangling routines to find Hosts file
in normal locations (Sys folder, launch folder?)]

••Gopher impressions

One of the impressive things I remember when I first when to a large
university after growing up in a small town, was finding the library.
My home town library was a place of discovery and enjoyment for me.
When I went off to college, the library was one of the first things
I looked into.  I spent much time looking around this mountain of
knowledge, and I learned much, perhaps more than from classes, in these
big libraries.

That is the way Internet Gopher strikes me -- like going from a small
town library to a big university one.  It is a very simple but
powerful way to bring information from anywhere, locally or world-wide,
to your personal computer.  It is easy to set up gopher servers.  It is
Very Easy to use the gopher clients.

The IUBio Biology Archive is now available thru internet Gopher.
It is reached at host "ftp.bio.indiana.edu", standard gopher port# 70,
with path="".  You may also find links to other Biology gophers at this
site, including North American, European and Middle East sites, at the
time of this writing.

Internet gopher is pretty easy to learn to use.  Gopher and WAIS provide
somewhat different protocols for serving information out to clients over the
Internet.  Gopher is strong on browsing -- you can find new things just by
pointing at lists.  WAIS is strong on linking together many dispersed
servers to answer a given question.  I think they both are good, but I
think Gopher is an order of magnitude easier to learn, and install, and
consequently will be more useful to more people.

Thru the IUBio Biology Archive, you can, for instance, fetch a single sequence entry
from Genbank by providing its accession number or locus name as the question:
   Fetch by accession number <?>
   X51902
   -- will fetch the sequence "Alcaligenes eutrophus gene for 10Sa RNA"

Or you can provide key words:
  Search by keyword, author... <?>
  Acanthamoeba castellanii
  -- will list all sequences of that species of amoeba.


••New Gopher

This creates a new Gopher document, including default links to a few
Gopher servers.

To the astute computist: The default gopher links reside in application
resources named "IGo4".  You can add to or replace these using ResEdit,
by copying a link from an open Gopher document, and pasting it into
an "IGo4" resource in ResEdit.

[ This regards the default servers listed in a New document.  You need
to use Resedit to change the "IGo4" resources in Gopherapp.  The first one,
ID 0 "Bundle Stuff" must remain as is.  The other ones can be deleted, replaced
or edited.  The easiest way to put a new "IGo4" link into this resource is to
(a) Run GopherApp, open gopher doc w/ link, Select and COPY the link.
(b) Quit GopherApp, open it from ResEdit, open "IGo4" apps, create new IGo4 item
then PASTE the (text) of the link into the Ascii side of the IGo4 edit box.
]

••Gopher Documents

The New and Open commands on the File menu will let you create new
or open old Gopher files.  You should use Copy/Paste and dragging gopher
items, as well as the "New gopher link" and "Edit gopher link" commands
to create gopher document files that suit your tastes.

You may also edit a gopher document file as if it were a TEXT file (Open
as Text).  When you save such a file, it is saved as a TEXT type.  You
can convert it back to a GopherApp document by using the "Gopher..." command
from the Internet menu, while holding down the OPTION key.  Open the
document then resave it as a Gopher type (IGo4).  The prefered way to
edit gopher links is with "Edit gopher link" command however.

A really sneaking option (I was out of User Interface hacking time) is
to SAVE AS with OPTION key down.  This creates a document in the style of
Gopher Server link files:
    Name=bob
    Type=0
    Path=....
However, GopherApp cannot (yet) re-read these.  You need to convert to TEXT
and move to your Unix server.


••Gopher Prefs

This dialog allows you to set some personal preferences for Gopher views.
Some of these features (single window) are not ready yet.

Your choices for display font, size, and item information (host, port,
path, ...) are selected in the Prefs window.  Also default font and
size for text views.

The TCP Timeout sets how long the app will wait for data from a remote
connection.  Value is in 60ths of a second, so 3600 is 1 minute.  Use
a large value for slow connections, like SLIP.

For the "Default new links" preference, the "Save front window" button
will cause the topmost Gopher window to be saved as your default links
list, available with the New menu item.  The "Restore app defaults" restores
those to the list of 'IGo4' resources stored inside GopherApp.


••More about Gopher

Here is an introduction to Internet Gopher from one of its developers,
Paul Lindner:

The newsgroup alt.gopher has been created to for developers and
users of the Gopher software developed at the University of Minnesota.

Here is our little gopher spiel, in case you're interested:

What is the Internet Gopher?

The Internet Gopher is an information distribution system. It combines
features of elec- tronic bulletin board services and databases,
allowing you to either browse a hierarchy of information, or to search
for the information you need using full-text indexes. Gopher can also
store references to public telnet sessions, CSO phone book servers,
finger-protocol information, and sounds.

The Internet Gopher software was devel- oped by the Computer and
Information Services department of the University of Minnesota. The
software is freely distributable.


What Information is Available?

There is much diverse information stored on various Gopher servers:
computer documentation, phone books, news, weather, library
databases, books, recipes, etc.

We use Gopher at the Microcomputer Helpline to quickly answer
questions using our large user support database. In addition to our
own information, we have over 6000 information items from various
hardware and software ven- dors. While it's a good tool for our own
internal use, anyone may search the database. This means fewer calls
to our helpline, resulting in better, faster service.

The Gopher system can keep track of campus phone book servers.
Currently you can search seventeen University phone books.

Quite a bit of news is in Gopher. Two campus newspapers: The Minnesota
Daily and The Daily Texan are on line and searchable.  National
Weather Forecasts for the entire nation are also available. For
Clarinet subscribers we provide a full UPI news feed that's indexed
hourly.

The electronic books published by the Gutenberg Project are available
in Gopher. These include classics such as Moby Dick and refer- ence
works such as the CIA World Fact Book.  The Hacker's Dictionary and
the Periodic Table of the Elements are available too.

Gopher users can also get at information that is only accessible on
terminal based infor- mation systems. Gopher can store links to these
sites. You can easily start a telnet session to many libraries and
information servers with the press of a key or click of the mouse.

Naturally we have some fun information as well: humor, recipes, jokes,
etc. There's a wide variety of data, with more coming on-line all the
time from a multitude of sites on the Inter- net.


How does it work?

Information is stored on multiple servers, connected together in a
network. This allows for capacity to be added to the system in small,
inexpensive increments. It also allows the Gopher system to cross
institutional boundaries, since other servers can be "linked" into the
sys- tem easily. Large indexes can be spread over multiple servers,
resulting in significant speedups.

You may use the PC, Macintosh, NeXT, Xwindows, or Unix Terminal
Clients to access the Gopher system. The client connects with a "root"
gopher server which is an entry point into the Gopher. There can be
many different entry points. This allows a certain amount of freedom
in organizing the information. Local or fre- quently accessed
information can be put higher in the hierarchy for different
organizations (i.e.  the Library root server would have a library
search at the top level, whereas the Music root server would have it
lower)

At the initial connection, the root server sends back a listing of the
objects in its top level directory. These objects can be:

 Directories,
 Text Files,
 CSO Phone Books,
 Search Engines,
 Telnet References or
 Sounds


Each object has associated with it a User displayable title, a unique
"selector string", a hostname, and a port number. The client then
presents the user with the list of titles, and lets them make a
selection. The user does not have to remember hostnames, ports, or
selector strings.  The client takes care of this.

After the user makes a selection, the cli- ent contacts the given host
at the given port and sends the selector string associated with the
object. The client will do different things, depending on what type of
object was selected.  The client may display a new directory, show a
text file, or prompt the user to search a CSO phone book. This process
continues until the user decides to quit.

Since gopher uses a simple protocol, we and others were able to
develop clients and servers on many platforms quickly and easily.


How do I access Gopher?

Client software for Macintoshes, PCs, NeXTs, X Windows, and UNIX
terminals is available for anonymous ftp from

  boombox.micro.umn.edu

in the directory

  /pub/gopher

Or, if you just want a quick look at the UNIX terminal curses client,
telnet to the machine

  consultant.micro.umn.edu

and log in as:

  gopher

We highly recommend running the client on your local personal computer
or workstation.  These local clients have a better response time and
an easier user interface.

•History

GopherApp -- First public release on 25 Mar 92. Derived from biosequence
analysis application SeqApp.

SeqApp was started Sept. 1990 as MacApp sequence editor/analysis platform
on which analysis programs from other authors, typically command line
w/ weak user interfaces, could be easily incorporated into a useable Mac
interface.

21 Apr 92 minor update: corrected GopherApp file creator signature,
added domain name server lookup cache.

12 May 92, v1.1b8 -- various bug fixes, chased out several TCP related problems,
added edit gopher link, new gopher link. Partial backgrounding during long
gopher fetches -- not working completely yet.  Known bug of limit to path
length of Pascal string size [255] that truncates, for instance, some
long wais-gatewayed document paths.

26 May 92, v1.1b36 --  New TCP timeout option makes this a SLIPpery app,
default item font now has sane value, help file now is
always found when in app folder, TCP userbreak handles update
events, but still doesn't background properly or spin cursor,
text view now has default font pref, now can save default new links as
prefs.
