The early skinny on Arachne scripting.
This is probably a bit premature because there will be further work done in
this area, but it can't hurt to become familiar with the existing scripting
capabilities of Arachne so we can try to help development. If no one uses
scripting, there won't be any wish list or bug reports.
An Arachne script file has an ASF extension. It is simply a list of URLs
that will be visited in sequence, as rapidly as possible. Put that way, it
seems pretty useless, doesn't it ? That isn't the case, because of what
Arachne accepts as a URL. We naturally think first of web locations, but
you can call local files such as Arachne pages, images, sound or video files,
Arachne .DGIs, DOS .bats via .OOKs and .EEKs, Arachne protocols like dialer
and hangup, reload and exit, and even another .ASF as long as it is the last
line in the current ASF. The primary limitation with current scripting is
its inability to make decisions and branch.
Your programmable hotkeys can be used to call .ASFs. You could have shiftFn
programmed to call an ASF that temporarily changes your configuration to get
or send mail via a different ISP or with a different email address and then
restores your setup to normal. Michael suggested to me that that would be a
better way to handle mail than some of the methods I proposed in earlier
columns, but I had been focussing on automatic operation driven by DOS
and time which made the methods described both useful and valid.
For an example of scripting, select ASF_HELP.asf in your main Arachne dir.
For a list of SOME of the possible Arachne protocols that you might use in
your script, view AEXTHTML.txt. This is just a starting point as some of
these protocols do not work yet when used in an ASF, and there are many
unlisted ones that do work.
Non-web protocols tested as working in ASFs:
Protocols tested as NOT yet working in ASFs:
Protocols not tested:
To test a URL or protocol for viability in a .ASF, type it into the
the URL window and hit ENTER. It has been discovered that the result
in a script will be the same as the result of this test. Note: Do not
put blank lines in your script.
I use a script to help reduce the waste of online time caused by my
forgetting to hangup before reading mail. Arachne.cfg has a variable:
AfterPOP3. If this is simply set to arachne:hangup, Arachne will display
an error screen after the hangup when it tries to load the inbox because
it is no longer online. Instead, I set AfterPOP3 file://donemail.asf.
Heard on local college radio: A technical commentator reports that a certain
software package known as "W2000" is more stable and secure than DOS, an OS
the company is now trying to hide. I tuned in late, so I didn't catch what
planet he was vacationing from.
