Re: How to best model the current state of a project

This topic has come up a few times on the lists. But I agree, the 
documentation is pretty bad with regards to project tracking. Probably 
because TJ offers quite a variety of ways to do it and everybody needs to 
find the way that fits his or her project management style best.

Let me outline them quickly:

1) The lazy way:

Use 'complete' to document what's done. For completed tasks insert the real 
start and end dates to avoid floating.

2) The meticulous way:

Use 'booking' to record all done work and schedule the scenario on 
'projection' mode.

Those are the methods that we have used, but there are probably other ways to 
do it as well. It all depends on how much work you are willing to invest and 
how accurate the schedules need to be.

Have you every tried compiling other Qt programs? This has probably nothing to 
do with multithreaded Qt or not. Your libfontconfig doesn't seem to match the 
rest of your X libs.

Redefinition of macros?

Hi there,

is it possible to redefine or undefine a macro?

Thanks,
Uli

no this is currently not supported. The TaskJuggler syntax was designed to be 
very error resistant. So all items need to be declared first or redefinitions 
result in an error message.

In that sense an 'undefine' statement for macros would be the right way to 
implement it. So far nobody asked for it but it would not be much work to add 
it. What do you need it for? 

I'm generally very familiar with macro languages such as the C preprocessor or 
even m4. I added the macros to TJ because it is a powerful feature, but hoped 
that people would use it only scarcely. I guess you proved me wrong now. ;)

Re: Redefinition of macros?

Chris,

I have to apologize not to explain the purpose of my request. The idea 
behind is that I do have to schedule many different projects in parallel 
tightly connected by usage of shared resources. I therefore find it more 
comfortable to define one huge TaskJuggler project rather than following 
the approach outlined in http://www.taskjuggler.org/example.php "The Big 
Project".

In my approach each project is mapped to "level 0" TaskJuggler task 
which is stored in a separate .tji-file including its subtasks. The 
tji-files are maintained by different people. To ease definition of such 
a task, and because many of these tasks (each representing a project) 
are quite similar in structure, I would like to provide a sort of 
template. Such template would start with a couple of macro definitions 
that will be reused inside the body of such level 0 task. As a 
consequence the redefinition of macros at the beginning of each 
.tji-file is required.

Of course this approach assumes a local scope for macro definitions with 
respect to macro and parameter substitution. Thus, macro redefinition 
might not really lead to the solution I have in mind.

Thank you,
Uli

P.S.: I like the 2.1 version including the TaskJuggler UI very much. 
Great job! Do you plan to enable the printing of these nice Gantt-Charts 
  of the project view?

You can do this actually today. The macro lifetime extends over the included 
files, but not over global file scope. So there is a difference between

taskjuggler a.tjp (where a.tjp includes b.tji)

and

A simple shift manager

Hi list,

I have just began to use taskjuggler and went through
the 3 examples provided with the package. I also read
the docs. The program is very impressive, but there is
one simple thing I must be overlooking.

I'd like to use it to plan shifts - but not
automatically. We have 6 workers. At the beginning of
every month, we all discuss the shifts we will do for
the next month (every day is different and there is
nothing automatic).

Which commands do I need to do this? Is there an
example file on the internet for this?

Best regards,
Ralph

First you need to define your resources and their availability (vacation, 
workinghours, shifts). Then you need to define the tasks that you want them 
to do. Now you allocate the resources to the tasks. The allocation can again 
be restricted to certain shifts. If you want TJ to pick the resource, you can 
just allocate all resources as alternatives and pick a selection algorithm 
that suits your needs. See the manual on 'allocate' for more details.

Project Tracking HOWTO

Hi,

the topic of project tracking came up a few times on this list already, so 
I've decided to add a new chapter to the manual. This describes in detail how 
you can use TaskJuggler to track a project once it got started. You can find 
it in the CVS version or on our web site: 
http://www.taskjuggler.org/manual-cvs/book1.html

Feedback welcome.

Chris

Hi Chris,

Thanks, I got it to work how you said. 

But the problem is that we have no fixed working 
hours and all work on the same never ending task...
so it needs no selection algorithm for a task and 
should not have fixed start/end times because 
this varies from day to day and we do not know 
in advance when.

I.e. For Tom we have:
Mon, 25.04.2005: Early
Tue, 26.04.2005: Early
Wed, 27.04.2005: Medium
Thu, 28.04.2005: Late
Fri, 29.04.2005: Late

Can I do something like this?
resource 
 Tom "Tom Smith" 
  { Early 2005-04-25 
    Early 2005-04-26
    Medium 2005-04-27 
    Late 2005-04-28
    Late 2005-04-29 
   }
