Hi,

I have just subscribed to the mailing list and seen your post, so I am 
sorry for not replying to it directly. 

I have lately done something similar. Essentially, the problem is that the 
set of defined templating keywords has to be known to the template engine. 
I am not a guru here, but here is what I had to do to introduce a new 
template element:

- modify hgweb_mod.py and register a new template keyword - required 
  registering the template callback - look at for example at the 'footer' 
  implementation

- modify the .tmpl files to use it (that's what you did)

Anybody knows a more simple approach?

To give you an idea, attached is a small patch that introduces 'logo' 
support based on the hgrc configuration.


Cheers,

Jan

logo_{alt,src,link} templates for hgweb

- hgrc supports a new configuration parameters that allow setting logo
  template. This template is than available for use in the web
  interface .tmpl files.

- example configuration:
[web]
# customized templates for that use the logo
templates = /srv/www/hgweb-templates/
# static files modified also site specific
static = /srv/www/example.org/hg/static
# custom style tailored from git and extended with logo
style = git-web-with-logo

# logo settings
logo_link = http://hg.example.org/
# the logo has to be stored into /srv/www/example.org/hg/static
logo_src = hg-logo.png
logo_alt = Some alt text when logo is missing
