[Kde-pim] PIM/KDE Grantlee plugins

[Daniel Vrátil]

Hola guys,

I've spend some time during past few days playing with IncidenceFormtter in 
KCalUtils to use Grantlee templates instead of assembling the HTML in-place, 
which I find ineffective and horrible to read/extend/maintain. Yes, I could 
just add 10 lines of code to make it show comments in todos which I need for 
Phabricator, but this was more fun :)

So far I have successfully created templates for todos, events, journals and 
free/busy reports, the ITIP preview is still to be done, but there I probably 
need to co-ordinate with Sandro who's working on the ObjecTreeParser 
refactoring. I submitted the first part of the port as review for further 
comments and discussion (https://git.reviewboard.kde.org/r/125331/). I think 
it's better to do this in smaller steps, the ITIP formatter still works, so we 
can port it at any later time (I also suspect it will be much more work).

Anyway, in order to use Grantlee effectively I had to write custom Grantlee 
localizer that uses i18n() instead of tr(), and a plugin that provides custom 
tag for inserting icons - e.g. {% icon dialog-ok small %} that generates <img 
src="/usr/share/icons/.../dialog-ok.png" width="16" height="16" /> using 
KIconTheme::iconPath().

Since the longterm plan is to use the template system in the new OTP as well 
as in other places, this code should IMO be moved to some shared place - 
something like pimutils, pimcommon, libkdepim, I don't know :) But it should 
be outside kdepim.git so that we can use it from kcalutils and other places 
too. Do you guys have an idea where we could put this? Or should we already 
look into splitting some of the library that Laurent has been working on in 
kdepim.git into it's own repository and put the code there (if that's the 
plan).


Cheers,
Dan

PS: if anyone can move T749 to Done and T835 to In Progress in Phabricator, 
please do so for me, Phabricator is refusing to talk to me the past couple 
days (T841 if anyone's interested).
