Re: Code snippet hosting?

People often post a function, a script, or a complex query that is
general enough to be worth keeping but perhaps not appropriate for
pgfoundry or the documentation. MySQL has a code snippet service for
that: <http://forge.mysql.com/tools/>. I think something like this
would be quite useful for PostgreSQL as well. Perhaps the wiki could be
used for that; I'm not sure.

Ideas anyone?

No ideas for implementation - but it would be a great service to the
community and a big + for Advocacy.

It wouldn't be hard for me to rebrand privatepaste.com and add the few
additional pieces (and perhaps remove others) for this.

Cool idea. With a little massaging the wiki could accomodate this ...
there are syntax highlighting plugins we could install to get the code
snippets looking nice. Wouldn't be as fancy as the MySQL site you
linked, but it would do the job.

Just make sure there are appropriate category tags.

Maybe we should use a separate namespace for this? Snippet: or
something like that ... not sure if this is a good idea.

Django has something like that [1]. Just a thought.

Indeed. If we use categories properly, that gives us (for free) an
alphabetical index of all available snippets.

I'm lukewarm about creating a namespace for it. I reckon we could
just allow people to create pages for their snippets and if at some
future time we start getting into page name collisions, we cross that
bridge. Another option, if the snippets start cluttering up the Main
namespace, is to make them subpages.

So, anybody got a useful code snippet they would like to volunteer as
a first test subject? =) Failing that, we could write up the
Mandelbrot recursive query demo.

Why wouldn't we just use the wiki for this?

Um. That's ... what we're talking about?

The conversation you're quoting was about which piece of code we might
use, to start playing with a wiki implementation.

Yeah, this was *supposed* to be a feature of GForge when we adopted it.
It wasn't until after we lit up GForge and moved the accounts over
from GBorg that Tim let me know that the snippets stuff didn't work and
he was planning on dumping it.

In theory also, Roberto Mello was going to come back a year ago and
re-build the function repository, but he never did.

So let's use whatever we can get up quickly. If we're going to use a
wiki for this, though, can it be a separate wiki from
wiki.postgresql.org? If I'm searching for a specific function, I don't
want to hit dozens of pages about database conversion and commitfests.

The snippet I use the most is already on the Wiki in the admin section:
http://wiki.postgresql.org/wiki/Disk_Usage

I was recently poking at the now defunct PostgreSQL CookBook:
http://web.archive.org/web/20031207045017/http://www.brasileiro.net/postgres/cookbook/

Two problems with grabbing a bunch of those: the licensing is unclear for
code submissions to that old site, and not everything will still work
against a current release.

But it does suggest some useful categorization for organizing a collection
of snippets.

I disagree. I think we should keep it under the main wiki. Just create a
new section.

Ugh, please no. We have too many domains and sites as it is: we should
be moving towards consolidation, not expansion.

If the wiki needs something to get the code snippets looking nice, etc.,
let me know, I've gotten pretty handy with MediaWiki lately. Speaking
of which, we should upgrade the wiki to a recent stable version (and upgrade
the PG backend as well)

A nice format, with an easily distinguishable tag would be sweet. Then we
could publish a feed of the changes, and let people re-mix/re-format as
they'd like.

Greg - could you make something based on the 'show highlighted code'
example? That included a section for tags, and a description?

i.e. http://forge.mysql.com/tools/tool.php?id=85

This should be just a matter of installing a syntax highlighter
mediawiki extension, like enscript, GeSHi or ASHighlight

Alright:

http://wiki.postgresql.org/wiki/Snippets
http://wiki.postgresql.org/wiki/Snippets/Mandelbrot_set

Now someone install all the plugins to do the syntax highlighting on the
subpage and produce some kind of recently-added or most-often-viewed index on
the superpage.

Or scrap it if you have a better idea. ;-)

Okay, Stefan was kind enough to install the syntax highlighter
extension. I gave it a try and it seems to work great -- thanks, Stefan.

I don't know how to create an index of subpages in the superpage, but I
added category tags so you can see the snippet index here:

Nice. It does a good job of highlighting the SQL.

I took the liberty of adding the results of the Mandelbrot query to
the page while I was there =)

We could also make a template for a snippet "infobox" that appears
floated to one side and shows some pertinent attributes of the
snippet, such as what language it's in and which version of Postgres
it works with, any dependencies, etc.

Probably relying on the category index is the right way to go ... the
superpage could just give an intro explaining what snippets are, and
maybe how to go about adding them, and link to the category page.

Cheers,
BJ

+1 to that too!

(Note that I added a category tag for the language too.)

Maybe the subpages approach isn't so great then, because the
alphabetical index in the category listing puts everything under "S" now.

I suggest that we keep /Snippets as a kind of info and index page, but
move the rest to the top level and rely on the category tag exlusively.
