-- WHAT IS POPLOG? ----------------------------------------------------
Poplog is a multi-language interactive software development system
including incremental compilers for Pop-11 (the core language), Prolog,
Common Lisp and Standard ML.
It also includes a powerful, programmable editor VED, with a
multi-window version XVed, which is similar in its facilities to Emacs,
though some users find it easier to learn to use. VED is programmable in
Pop-11.
Further information about Poplog and Pop-11 is available from
ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/poplog.info.html
It was developed originally by Sussex University and was previously a
commercial product, sold by Integral Solutions Ltd (who use it in their
award-winning data-mining package Clementine). It is now freely
available via FTP. Information about availability will be provided in
ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/freepoplog.html
Version 15.53 is the first free version of Poplog supplied with full
system sources. It should be regarded as a "beta" test version, and will
be developed and updated from time to time.
-- GETTING POPLOG -----------------------------------------------------
Fetch the file for your system from the Poplog distribution directory:
ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/new/
(Later there may be mirror sites.)
Poplog is distributed in the form of a gzipped tar file. Current
versions have names indicating platform and version, like
linux1553.tar.gz
solaris1553.tar.gz
Later a different naming scheme may be used, as more versions become
available.
These gzipped tar files may be between about 10Mbytes and 18Mbytes
depending on the version and whether system sources are included (now
the default for new versions of Poplog.)
When unpacked Poplog will require more space, of course, about 61 Mbytes
for the Solaris version, less for linux.
-- CREATE A DIRECTORY FOR POPLOG --------------------------------------
After you have fetched the gzipped tar file you will need to create a
directory $usepop for the main poplog system, and a "local" directory
$poplocal in which you can place additional packages, etc.
Choose a directory in which to install Poplog. On a unix system this
might be something like
/usr/local/poplog
If you create a new directory below that each time you install a new
version of poplog, that will make it easier to manage changes of poplog
systems, and test out a new version while an old one is still in use.
So for poplog V15.53 create a subdirectory called
/usr/local/poplog/v15.53
-- SET $usepop - The "root" directory for the current version ---------
Set the Unix environment variable "usepop" to refer to the installation
directory. E.g. in a C-type shell
setenv usepop /usr/local/poplog/v15.53
in other shells
usepop=/usr/local/poplog/v15.53
export usepop
Henceforth the installation directory will be referred to as $usepop.
-- CREATE AND SET $poplocal/local -------------------------------------
It is useful to have a directory in which you can add additional poplog
libraries imported from elsewhere or created by you. This could be
/usr/local/poplog/local
Create it thus:
mkdir /usr/local/poplog/local
In that case you could do in a C-shell
setenv poplocal /usr/local/poplog
or other shells:
poplocal=/usr/local/poplog
export poplocal
Then the local directory will be $poplocal/local. In there you can
create directories called com, auto, lib, teach and help, etc.,
mirroring the structure in the main poplog directory. These local
extensions can be preserved when you upgrade poplog later.
It may be convenient to set $local to be equivalent to $poplocal/local
-- Installing Poplog on a Unix system (e.g. Linux, Solaris) -----------
It is assumed that you have copied the tar file, which, will be referred
to as
poplog.tar.gz
although the "poplog" bit will be different for different versions of
Poplog. E.g. it may be something like linux1553.tar.gz or
solaris1553.tar.gz
The directory where the tar file is kept will be referred to as
.../
so the tar file will be referred to as
.../poplog.tar.gz
After setting "usepop", as described above, you can install poplog in
the directory you have set to be $usepop, e.g.
/usr/local/poplog/v15.53
If you wish to install it somewhere else you can do so, but then all the
instructions which follow will have to be changed to use the correct
path name for the installation directory.
-- How to install Poplog ----------------------------------------------
You should be able to extract the poplog system into your own directory
$usepop previously created, as follows
# 1. Make that your "current working directory"
cd $usepop
# 2. Extract the Poplog system from the tar files
zcat .../poplog.tar.gz | tar xf -
(replace the dots and "poplog.tar.gz" as appropriate).
The above could take several seconds to several minutes depending on the
speed and size of your computer. It may consume 50 Mbytes of file space
on your hard drive or more. (You can later save space if you wish by
deleting unwanted sources and saved images.)
The above command will unpack the poplog tar file and create the
directory
$usepop/pop/
e.g.
/usr/local/poplog/v15.53/pop
If you then check out what is in that directory
ls -F $usepop/pop
you'll find that it includes directories like these (and maybe more):
adm/ doc/ help/ lisp/ plog/ pop/ src/ ved/
com/ extern/ lib/ obj/ pml/ ref/ teach x/
There is an overview of most of the Poplog directory structure in
$usepop/pop/doc/sysspec
which can be read in the poplog editor VED using the command
ENTER doc sysspec
That file may be slightly out of date.
-- Preparing to run pop-11 and other poplog languages -----------------
The executable images are in the sub-directory pop/pop/ along with some
other things.
Try
cd $usepop
ls -l pop/pop
This should include the main executable file, basepop11, linked to
various files representing names by which poplog can be invoked, e.g.
pop11, prolog, clisp, xved, etc. how it starts up will depend on how it
was invoked. Normally it will start up saved images which can be found
in
$usepop/pop/lib/psv
e.g.
startup.psv
The basic poplog and Ved/Xved saved image. This will
be run by the pop11 command, which is equivalent to
basepop11 +startup
xved.psv
A version which goes straight into Xved on startup
prolog.psv
clisp.psv
pml.psv
Precompiled versions of Prolog, Common Lisp and ML.
-- Setting up environment variables -----------------------------------
Before you can run any of Poplog you have to set up various environment
variables, as follows
If your shell is csh, or tcsh, then do
source $usepop/pop/com/poplog
Alternatively, using bash or ksh, or sh you can do
. $usepop/pop/com/poplog.sh
The command sets up several environment variables used by pop-11 and
other parts of the poplog system, and extends $PATH
You are now ready to run the programs.
-- Installing Poplog on a PC running Windows 95/98 --------------------
Fetch the file from the installation directory, by following the link in
ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/freepoplog.html
Copy the gzipped tar file onto your PC and use the Winzip program to
unpack it. There should be ten directories and a README file.
DISK1/
...
DISK10/
Look inside DISK1. Run the program
SETUP.EXE
Then follow instructions including specifying an installation directory.
This will put a file README.TXT in the installation directory. You
should read that file for further information.
-- First check on installation ----------------------------------------
Under Unix try to run this:
pop11
On Windows, select Poplog from the Programs menu (accessible via
Startup).
This should print out something like:
Sussex Poplog (Version 15.53 Mon Jul 12 19:45:02 BST 1999)
Copyright (c) 1982-1999 University of Sussex. All rights reserved.
Setpop
:
It ends with a colon, the standard Pop-11 prompt. You can type pop-11
commands directly to the prompt. They will be compiled and run. Then you
can type more commands, etc. Usually, however, it is more convenient to
run Pop-11 from inside an editor, which saves re-typing if you make a
mistake.
If you get the pop11 startup prompt you can check that everything is
fine by computing factorial 10000, by typing in a procedure definition,
then a command to run it:
;;; define a factorial function
define fact(x); if x == 0 then 1 else x * fact(x-1) endif enddefine;
;;; Test it
fact(1000) =>
The answer is a very big number which takes about 29 lines to print
(depending in the width of your screen).
You can check that it gets the right answer by computing two factorials
and dividing them
fact(1000)/fact(999) =>
which should print out
** 1000
You can leave pop-11 by typing CTRL-D, (or "bye).
Test that the pop-11 eliza works, as follows
# run pop-11 from the shell
pop11
then when you get the colon prompt, type the following to autoload the
eliza library program and then run it.
eliza();
This will compile the Eliza program, then run it. Instructions will be
printed out.
Type each assertion on one line, ending with the RETURN key (not the
ENTER key).
When you have finished with Eliza, type:
bye
to get back to the Pop-11 prompt.
-- Testing XVED (Not available under Windows) -------------------------
XVed is a multi-window version of the Poplog VED editor. If your system
includes Motif, XVed will also provide a scroll bar and menus at the top
of each window.
Leave Pop-11 and type
xved &
This should run the X version of Ved.
If you then type
ENTER teach teach
you will get an online tutorial on the editor. (There are more up to
date tutorial files available from the Birmingham FTP site.)
-- Testing other languages Provided with Poplog (on Unix) -------------
To run Poplog prolog, give the command
prolog
which is equivalent to
pop11 +prolog
To run Poplog Common Lisp give the command
clisp
which is equivalent to
pop11 +clisp
To run Poplog ML give the command
pml
which is equivalent to
pop11 +ml
All of these will run a process which includes the editor VED and the
Pop-11 system. Online documentation explains how you can make these
languages call Pop-11 and vice versa. To build a system that contains
more than one language extension you can copy and edit mk* files in
the directory
$usepop/pop/com/
Some combinations are already there, e.g. mklispplog and mkploglisp
which show now to use the existing Prolog image to build a new layered
saved image with Common lisp, and how to use the existing Common Lisp
image to build a new layered saved image with prolog.
-- Documentation directories ------------------------------------------
There is a huge amount of online documentation of varying kinds and
formats.
$usepop/pop/teach
Tutorial introductions to the editor, Pop-11 and AI techniques
(Many of the latter are out of date. More up to date
versions will be added later.)
An overview file is
$usepop/pop/teach/teachfiles
$usepop/pop/help
More terse help files on many aspects of Pop-11 and VED
An overview file is
$usepop/pop/help/helpfiles
People who are used to older versions of Poplog may find it
useful to study
$usepop/pop/help/news
$usepop/pop/help/plognews
$usepop/pop/help/lispnews
$usepop/pop/help/pmlnews
$usepop/pop/ref
Extremely full documentation on Poplog, Pop-11, the Poplog
virtual machine, VED facilities, the operating system
interface, the external language interface, etc.
This documentation is mostly written for experts. See the
overview file
$usepop/pop/ref/reffiles
$usepop/pop/doc
Some out of date overview files, which may still have some
useful information but are likely to be incomplete. E.g.
there is a Ved manual and a Userguide.
$usepop/pop/x/pop/teach
$usepop/pop/x/pop/help
$usepop/pop/x/pop/ref
Tutorial, summary help, and reference documentation on the
Poplog X window interface, including the Poplog widget set.
In particular a lot of information about how poplog starts up
and how you can tailor it is in
$usepop/pop/ref/system
REF SYSTEM
$usepop/pop/help/initial
HELP INITIAL
$usepop/pop/x/ved/teach
$usepop/pop/x/ved/help
$usepop/pop/x/ved/ref
Tutorial, summary help, and reference documentation on the
X-based version of the Ved editor (including multiple windows,
mouse driven interaction, etc.)
$usepop/pop/lib/objectclass/teach
$usepop/pop/lib/objectclass/help
$usepop/pop/lib/objectclass/ref
Documentation on the Objectclass system which extends Pop-11
with object oriented programming facilities, much as CLOS
extends Common Lisp
There is also documentation on the Prolog, Common Lisp, and ML language
subsystems.
$usepop/pop/plog/teach
$usepop/pop/plog/help
Prolog documentation
$usepop/pop/lisp/help
$usepop/pop/lisp/ref
Common Lisp documentation
$usepop/pop/pml/help
Standard ML documentation
All of the online documentation is formatted to facilitate reading in
VED. There is a package which tailors Emacs for use with Poplog
including documentation files. See
ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/emacs.tar.gz
-- Edit your login startup file ---------------------------------------
If the above tests show that pop-11 works, then you could put into your
.login
file the following lines, so that they are obeyed automatically whenever
you log in.
setenv usepop /usr/local/poplog/v15.53 #or whatever the version is
setenv poplocal /usr/local/poplog
setenv local $poplocal/local
source $usepop/pop/com/poplog
If you don't use .login because you use bash or sh or ksh try
usepop=/usr/local/poplog/v15.53 #or whatever the version is
poplocal=/usr/local/poplog
local=/usr/local/poplog/local
export usepop poplocal local
. $usepop/pop/com/poplog.sh
Optionally you can include
setenv poplib ~/Poplib
and then put any private poplog libraries of your own, not shared by
other users of the same machine in your Poplib directory, e.g. files
which configure poplog and the editor, init.p, vedinit.p, init.pl
etc.
After that you should be able to run poplog whenever you login.
Alternatively put those commands into a file called setup.poplog
and then run the file before you run poplog.
[This startup mechanism will be replaced and improved in later versions
of Poplog.]
-- -- Problems??
If it doesn't start up at all, or complains about missing files, then
you may have an incomplete installation, or you may have given an
incorrect command at some point.
If the attempt to run poplog does not work, you should record
EXACTLY what is printed out, and post a request for help to the
comp.lang.pop
newsgroup, or
pop-forum@cs.bham.ac.uk
-- Using Motif or Lesstif ---------------------------------------------
On most Unix systems, poplog is linked to use Motif, and you can ignore
this section. E.g. motif is included in versions of Poplog for Solaris,
Digital Unix, SGI, HP Unix.
However, Linux is not normally supplied with motif and poplog is not
linked to use it.
If you have lesstif or motif and you wish to have the benefit of extra
motif-based facilities in Poplog, you will need to re-link Poplog as
explained later, to take advantage of the facilities.
However, you can run poplog without linking if you don't want to use
Motif. You will then not be able to use propsheet, nor will Xved have
scroll bars or menus at the top.
However, the Birmingham RCLIB package which provides sliders, menus,
control panels, etc. will work without motif. It is available from
ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/rc.tar.gz
If you do try re-linking poplog to use motif, remember that this version
of Linux Poplog has not been fully tested with Motif (as far as I know)
and if you use Lesstif there may be bugs in Lesstif or incompatibilities
between that and the version of Motif for which pop11 was designed.
In that case you can restore the original version, e.g by reinstalling
Poplog from the ....tar.gz file or by using the newpop command to
re-link without motif, as described below.
If anyone manages to get it to work with Lesstif, please let me know.
-- What is included in Poplog?
When everything is working, you will find a system overview file in:
$usepop/pop/doc/sysspec
You can interrogate this from inside Ved with the command
ENTER doc sysspec
Please remember that it is at best a guide to the current version of
Poplog, and is likely to be out of date.
-- Prerequisites ------------------------------------------------------
Poplog Version 15.53 works with Redhat Linux version 5 or 6. I don't
know if it works with other versions of linux. If you find that it does
please let me know (email A.Sloman@cs.bham.ac.uk)
It also works with Solaris (various versions) on Sparc.
If you have any problems, please post a message to comp.lang.pop asking
for help.
-- Birmingham extensions to Poplog ------------------------------------
Local Birmingham extensions to Pop-11 are available for copying by ftp
from this directory
ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/
That directory has a README file explaining what is in all the
sub-directories and gzipped tar files.
The main local extensions are all available both in a browsable
format and packaged in gzipped tar files:
bhamteach.tar.gz
many local utilities,teach files, etc.
rc.tar.gz
rc_graphics extensions, control panels, GUI stuff
prb.tar.gz
Poprulebase
(a very flexible forward chaining condition-action
rule-interpreter).
sim.tar.gz
The sim_agent toolkit.
(This uses Objectclass, Poprulebase and RCLIB to produce a
toolkit for exploring architectures for interacting
intelligent agents.)
primerhtml.tar.gz
HTML version of the Pop-11 primer (also included in Poplog as
$usepop/pop/teach/primer
The HTML version has out of date information about poplog
distribution, and will later be brought up to date.
pattern.tar.gz
A small library extending the Pop-11 pattern matcher with the
"!" prefix. This makes it possible to use patterns with
lexically scoped variables.
popvision.tar.gz
The popvision library produced by David Young at Sussex.
(1997 version. Will be updated).
ved_latex.tar.gz
Ved extensions for driving latex (including a latex tutorial)
vedmail.tar.gz
Extensions and improvements to the VED interface for reading
and sending mail
vedgn.tar.gz
A collection of utilities for reading and posting news from
inside the VED editor. This completely supersedes the VED_NET
library distributed with Poplog.
contrib.tar.gz
A collection of libraries and documentation contributed at
various times. It includes code from various books such as
the Gazdar and Mellish books on Natural Language processing
and Larry Paulson's book on ML
emacs.tar.gz
Emacs interface to poplog, by Brian Logan and others
Additional files and subdirectories (including the Pop-11 primer in
various formats) are described in the README file
ftp://ftp.cs.bham.ac.uk/pub/dist/poplog/README
-- Installing Birmingham local extensions -----------------------------
If you have not already done so, create a local poplog directory
cd /usr/local/poplog
mkdir local
cd local
You can then install other files whose names end in gz
E.g.
zcat .../bhamteach.tar.gz | tar xf -
zcat .../rc.tar.gz | tar xf -
etc.
where, as before the dots indicate the path preceding the file names
where you have installed or mounted the .gz files copied from our
system.
-- Making the local files accessible ----------------------------------
The default Poplog system assumes that the local directory is installed
in
$usepop/pop/local
This is not a good location, as the $usepop/pop directory may be
deleted when you get a new version of Poplog.
So you can make that file a link to the actual location thus;
cd $usepop/pop
chmod u+w .
ln -s ../local local
chmod u-w .
Instead of creating that link, you can change the definition of
$poplocal in your .login file, immediately after defining $usepop:
setenv poplocal $usepop
If you have done all that successfully it will have the following
effects:
The VED "ENTER teach" command should automatically access the
files in $poplocal/local/teach, as well as the system TEACH
directories e.g. $usepop/pop/teach
The "ENTER help" command will access files in $poplocal/local/help.
The files in $poplocal/local/auto will be automatically loaded when
needed, as described in HELP AUTOLOAD.
The files in $poplocal/local/lib can be compiled using either the
"lib" command which always compiles its argument, e.g.
lib readpattern
or, more commonly the "uses" command, which only compiles if the
library has not yet been compiled already, e.g.
uses readpattern
-- Re-linking Poplog to run with motif --------------------------------
You will have to do this if you have either Motif or Lesstif installed
and you want XVED to use them, or you want to use Propsheet.
Instructions for re-linking follow. You should do this while you are
super-user. In case it goes wrong, make sure that you still have the
original poplog.tar.gz file so that you can re-install the original
version without motif, as described above.
1. unprotect both $popsys and $usepop/pop/extern/lib, the latter
so that libXpw.so can be rebuilt.
chmod -R u+w $popsys $usepop/pop/extern/lib
2. Give this command to do the re-linking
$popsrc/newpop -link -x=-xm -xpw
Other options are described in the HELP NEWPOP file.
You can add this to prevent installation in $popsys
-noinstall
e.g. to see if it works.
After re-linking you should be able to run poplog if you have Motif
available.
-- Creating new saved images ------------------------------------------
If you have successfully installed the files from the Birmingham
bhamteachtar diskette you will find that the files in the directory
$poplocal/local/com/
include several shell scripts for creating and installing new saved
images which already have various local poplog extras pre-compiled. You
may be able to work out which ones you need e.g. by reading the files
called
$poplocal/local/com/mkstartup.nomotif
This creates a startup.psv image which already includes
objectclass, rc_graphic and various other useful things
which are part of the standard pop-11 configuration at
Birmingham, though not necessarily elsewhere.
$poplocal/local/com/mkall.nomotif
This can be used to rebuild a lot of saved images similar
to those installed at Birmingham.
The best way to proceed may be to make a copy of mkall.nomotif (e.g.
call it my.mkall) then edit it to prevent construction of the saved
images you don't want. You must include the startup saved image.
Then make sure that you have unprotected the $usepop directory using
this command:
chmod u+w $usepop
Run your new file, storing all the output in a log file
$poplocal/local/com/my.mkall >! mkall.log
It should take a few minutes, depending on the speed of your machine and
how many saved images you decide to create. Examine the log file to make
sure there are no errors (there may be some warnings, e.g. from
compiling common lisp, which you can ignore).
At the end you should have a new directory in which the saved
images have been built, which you can inspect
ls -l $usepop/templocalbin
If it has startup.psv and other files which look like the ones you want,
then, if you already have a file $usepop/poplocalbin remove or
rename it, and make the new one poplocalbin, i.e.
mv $usepop/poplocalbin $usepop/oldlocalbin
rename old directory if you had one.
mv $usepop/templocalbin $usepop/poplocalbin
rename new directory
make sure everything works ok, e.g. try running pop11, xved, etc.
If it all works, get rid of the old directory
rm -rf $usepop/oldlocalbin
You can later insert new saved images in $usepop/poplocalbin if you
wish, by copying files in $poplocal/local/com, such as
mkeliza.local and mkclisp.local
To find out more about saved images see HELP SYSSAVE, HELP SYSRESTORE,
and for full gory details REF SYSTEM. Some of the files use the mkimage
library, described in HELP MKIMAGE
-- The default system saved images ------------------------------------
NOTE: the saved images which come with the poplog system initially are
in
$usepop/pop/lib/psv/
These give you a more "primitive" version of pop-11 than the one we use
at Birmingham (e.g. it doesn't include rc_graphic and objectclass
precompiled). If you have created new versions in $usepop/poplocalbin
and you wish to get rid of the "system" versions to save space do this:
chmod -R u+w $usepop/pop/lib/psv
# make the directory and the files writeable by the owner
rm $usepop/pop/lib/psv/*
# remove the files
