[9fans] sources browser script?

[Benjamin Huntsman]

Speaking of web servers...
Is the script that creates the pages for the source browsing on plan9.bell-labs.com/sources/ included in the distribution or otherwise available?  It's pretty neat, and may be useful...

Thanks in advance!

That looks to be useful too, though that's not the script that sources is using to generate the pages.
The HTML source produced by webls.c looks different than what is produced by the pages.
Looks like the script in question should be called sources.tr?

Thanks!

i'm not sure what you mean by "script", the server in question
probably runs a tweaked version of webls.
it's also interesting to note that they managed to hide the
/magic/prog stuff  from the urls somehow.

i think it's a different thing.  there's an old thread where ehg
mentions it a filtering fs based on exportfs.

a filterfs would make this type of thing trivial; i have an outline of
one.  cgifs is already done (in fgb's contrib) and there's a cgi.c in
rsc's contrib that you could use with httpd to get it done in rc.

that's accomplished via /sys/lib/httpd.rewrite. from httpd(8):

          Httpd handles replacements pre-
          fixed with @ internally, treating the request as if it were
          for the replacement (without the @) but not informing the
          client of the rewritten name.

i have a version of httpd that accepts full regular expressions in
httpd.rewrite.

oops, forgot example:

^(.*)/download(.*)/$ 	@/magic/webls?dir=\1/download/\2
^(.*)/src(.*)/$ 			@/magic/webls?dir=\1/src\2

that's nice.

i wrote a slightly different version of webls to handle
coraid's mirror of sources (http://sources.coraid.com)
to allow the arguments to always be hidden and to
gloss over the differences between source directories
and source files.

that's yet another different thing.

the sources pages are internally rewritten
into /magic/something/path and then
ip/something (not released) gets run to
generate those pages.  ultimately it's just
a shell script wrapped around ls.
i'm sure one could recreate it in not
very much time.

it's not in the distribution, and in fact i don't
even remember the name of "something".

this is what i'm using.  it's not as pretty.
and the arguments are downright ugly.

adding the code to pretty-up the source listings
would eliminate the sleeze and ugliness
but i didn't want to drag all that code in too.

i added this to /lib/httpd.rewrite
# sleezy
bind /usr/sources /usr/web/sources/sources
bind /usr/sources /usr/web/sources/files

and this to /sys/lib/httpd.rewrite
/sources	@/magic/sources?r=/sources&f=/files&d=&p=/sources&dir=/sources

and use /n/sources/contrib/quanstro/sources.c
