If you want to see - and fix - the errors, press the "Edit"
button. Arena will start the editor specified in the EDITOR
environment variable (or using the "-editor <editor>"
option). The raw HTML will be inserted in the buffer along with short
error messages camouflaged as comments. You can set the maximum number
of errors to be flagged using the -badflags option.
After have been through an edit cycle, you will also see the
errors when toggleing the view button.
How can I edit HTML in Arena?
Start the editor as described above. Make your changes, save the
buffer, exit the editor and Arena will show you the edited
document. To save the file, either press the "SaveAs.." button and
type in a file name (no expansions are supported yet), or go into your
editor and save the buffer into the proper filename from there.
What are the
command line options?
How do I run Arena from behind a firewall? Has it been
SOCKSified?
Arena is not SOCKSified, but the CERN httpd proxy server
is. Therefore, you can get through your firewall by pointing
Arena to a proxy server running on the inside.
How does Arena cache documents?
Currently Arena doesn't cache in memory but uses disk for this. By
default, Arena will write fetched documents into
/tmp. E.g. http document from CERN's info server will go to
/tmp/http/info.cern.ch/... When exiting, Arena will delete
all cached documents and the corresponding directory structure. I.e.,
the disk cache is not persistant. Yet.
Also, if you run several Arena processes simultaneously on the same
machine you may want to specify different cache directories as they
will not be able to take advantage of each other's caches. See command line options.
What X11 resources can be set?
We are moving away from the platform-specific X11 resources to
style sheets that can roam the web. For more on how to write a style
sheet, see the draft
specification. Note that the syntax has changed over time, so make
sure you have the latest version of Arena. If you use an earlier
version, see the style sheet examples under the help page.
What hotkeys does Arena support? Why not <space>?
Arrow keys will move you around in the current document. Ctrl +
arow keys will take you page up/down and forward/backward in history.
Also, the following X11 keys are supported: Page Up (XK_Prior), Page
Down (XK_Next), Home (XK_Begin) and End (XK_Home).
We have not been supporting some of the other common hotkeys
(e.g. <space> for Page Down) because this may conflict
with future HTML editing. Enough people have asked for this to make us
reconsider.
Why doesn't index searching, hotlists - or other features - work?
Arena'a primary purpose is to be a testbed browser. These things
have been done before, so they're not that exciting.
How can I specify external viewers?
Arena supports mailcap files. If you have a file called
.mailcap in your home directory with this line in it:
image/gif; xv %s; quality = 0.95
Arena will display all images using the xv program instead
of inline. The quality statement is an indicator of how well
the application is able to display the data type. The HTTP server may
use this information to determine what format to send to you. The
default quality is 0.5.
Arena will also look for other mailcap files that the MAILCAPS
environment variable points to.
Help! Arena displays all images externally. What's wrong?
You have probably declared an external viewer for GIF
images. Arena does not distinguish between inline and "outline"
images; if a viewer is defined, it will be used for all images.
How can I make Arena work with proxies?
Arena (i.e. the library) reads the http_proxy
environment variable. Using csh, you could say
setenv http_proxy http://www4.cern.ch:8000/
This is also described in the CERN
httpd documentation.
On my sun, Arena can't find any hosts. What's the problem?
Name resolving. Try using "the other" binary,
e.g. arena-sun4-4.1.1-lresolv.bin or arena-sun4-4.1.1.bin.
Arena comes up in black and white (or grayscale) on my color
screen. Help!
There is probably another application hogging the colors. Try
quitting other applications (e.g. Netscape and Mosaic) and restart
Arena. Or, you can start Arena with the "-cm" command line option
(introduced in 0,98).
I submitted a bug report, but it still isn't fixed. Why?
We try to answer all reports and indicate a priority/complexity
factor. We do not have the manpower to fix/implement all requests. But
we hope you enjoy Arena anyway.
