Sorry, the post was from a wrong e-mail address.

Yeah, I was also using CppCMS 1.x.x for some time now.
But I had some legacy code which needed to be ported to 1.x.
I am sure, however, I am not the only one in this situation, so I finished
the article:
http://cppcms.com/wikipp/en/page/cppcms_1x_migration

CppCMS 1.x is vastly superior to 0.x - I realized that again during
porting ;)

I am not very fond of json as configuration format - even though it is very
good as data exchange format - because it lacks comments. What do you think
about a patch which let you switch to http://www.libelektra.org/ at
compiletime if preferred?

Basically it would be just an alternative implementation of
json::value service::load_settings(int argc,char *argv[])

What do you think?

Ok.

Steps to reproduce:
Go to http://cppcms.com/wikipp/en/page/cppcms_1x_json with firefox/chrome
Select some text of a sourcecode, press ctrl+c and ctrl+v or middle mouse.

I get:
my_object["name"]="Moshe";  
my_object["salary"]=1000.0;  
(Note the two spaces at the end of each line)

I expect:
No spaces at the end of lines.

It seems to be some problem within the syntax highlighter, which generates
a "<span>;  </span>" that adds these two spaces. It is a little bit strange,
because the line numbers are suppressed successfully.

Workaround:
Press "view plain" and copy there.

Yeah, the decision to drop CgiCC is ok, cppcms is now more homogen and
easier to use.
