Hi,
I'm coming up on some serious need for a project manager. I really only need
gantt chart creation at this point. I strongly dislike the Qt interface and
the need to use that if one wants to get a gantt chart output from the
process. I would much prefer being able to design my html charts, print them
as PDFs or take screenshots and embed them in presentations, send them to
others, etc. (as per tj3).
- is there any progress on an exporter for tj3?
- does anyone have a vague sketch of what needs to happen?
- can I do grunt work for someone to make this happen?
--- scan files for particular variables?
--- run test code, put together all the errors, and send back?
--- something else?
I'm happy to help... I just don't have the programming skills to do the
"real work" that needs to happen.
Thanks for any input,
John

Hi John,
if I understand you correctly you just need Gantt charts and not neccessarily tj3.
If that is the case org-babel and R may help.
There are at least two R-packages wich produce Gantt-charts: plotrix and plan.
May be that helps

I am roughly in the same boat as you are. I installed tj2 because the
tk3 manual says it is still unstable, but it's not an ideal solution
for me, as I have everything running on a mac, with tj2 running in an
ubuntu virtual machine (because of the Qt requirement).
..and in addition, I found that the exporter for tj2 - which does 90%
of what I need - was none the less missing a couple of features, so I
started adding them. Specifically I fixed:
- The project node was confused with the top task node.
I changed it so that the project gets its own node. Needed because...
- The project now respects an end date or a duration specified on the
project node
- I made the TODO state export as a flag so that you can use it to
filter reports
(eg generate a pending tasks or an in-progress tasks report)
- There was no way to easily add reports or other globals, besides
customizing
variables, so I added a globals and reports node.
- There was no way to handle taskjuggler features that the exporter
doesn't know
about, like scenarios. I fixed this by making a :TJ: drawer, into
which you can
dump any taskjuggler code you like (on any node), so that even if
the exporter
doesn't support a feature you want, you can still make it work from
org-mode.
I've only just got this working, and I haven't written a single line
of documentation for it, except for code comments.
> - is there any progress on an exporter for tj3?
My original thought was to post my changes here as a patch, to be
tested and hacked on by the group. Maybe it would be smarter to just
change it into a taskjuggler3 exporter? I just looked through "moving
from 2 to 3" section of the taskjuggler manual. On first glance, it
looks like the semantic changes won't bother the exporter, and that
the syntactic changes are relatively minor. So I am willing to give it
a whirl.
Given the foregoing, two questions for the group:
1. Is anyone interested in the changes I've made for tj2? I
unfortunately don't have time to document them, except in point form
as above, but I am happy to put together a patch and send it to the
list for others to bang away on.
2. Carsten, would you be interested in these changes, and/or a
taskjuggler3 exporter?
Thanks,
-Anthony

Oooh -- I'll definitely be checking these out. I don't have many resources
to manage and have no need for any of the account stuff... so maybe
something like this could work for me.

For the recent project I had to prepare, I did have to generate a
GANTT chart. I tried using TJ2 via org but found the current
implementation not suitable for my way of working. Instead of using
TJ, either 2 or 3, I simply created my own chart using tikz in latex.
To make my life easier, I created a number of latex commands for this.
I've now developed some code which will take an org table and create a
GANTT chart. Some of you may find this useful so I've attached an org
document with all the codes (emacs lisp + latex) along with an
example. I've also attached a PDF so you can see what I get.
The codes are not necessarily easily customisable so they may not do
what you want. For the types of project proposals I have to prepare,
the level of detail I have here is sufficient.

* table of tasks and milestones
The following table describes the tasks and other relevant
information for a project. Each line is an /entry/ and there are
three types of entry allowed in this table:
- task :: an actual task that has a start time, a duration and an end time.
- milestone :: a specific milestone in the project that has a start
time alone
- date :: a point in time that will be drawn as a vertical line in the
GANTT chart (e.g. start of each year).
Each element of the chart will be annotated with the content of the
/label/ column of each entry. The first column of the table is
ignored but I use it to number the entries. The last column, titled
/align/, is used to determine where to place the /activity/ text for
tasks, whether to the left or right of the bar or, if nothing is
specified, centred within the bar itself.

* some latex code for gantt charts
The following \LaTeX{} code is used to generate the actual elements of
the GANTT chart. The three colours used, to indicate /tasks/,
/milestones/ and /date/ lines, can be change to suit your own tastes. All
the rest of the code is not meant to be changed. Ideally, this code
should be in a separate /style/ file (see [[actions][list of actions below]]) and an
environment should be defined. As it stands, the code can only be
used once within a document unless the =gantttask= counter is reset
manually.

I'm very interested in these patches and would definitely like to see
them, documented or not. It sounds like they should be integrated in the
exporter.

I was hoping to have only one taskjuggler exporter which can handle both
tj2 and tj3, possibly depending on a defcustom.
Thanks

Sweet hack! And looks quite nice too.

I'm especially interested in a tj3 exporter. I have already installed
tj3 specifically to use with org-mode.

In the end, I also got the whole thing working for TJ3. I will send
you both files - I think it would be easy enough to merge the changes
together and make an exporter that works for both TJ2 and TJ3
depending on a defcustom. I'll send you everything in a separate
email. Maybe we'll get it all integrated together, and then move the
discussion back on to the list?
Best regards,
-Anthony

The main problem (not really a problem per se) is the need to define
sub-headings for tasks and so on for the exporter to find the
necessary project information. This makes sense for a running
project, say, but not for the type of document I was preparing (a
project proposal where the level of project workplan detail is much
lower). I found it much easier, for the latter, to use a simple
table. Of course, for a running project where you wish to keep track
of how far each task has progressed and allocations of resources etc,
my simple approach won't be of much use and a table is probably not
the ideal representation in any case.
A secondary problem (also not a problem) was the (current) lack of
babel integration for TJ. I have become addicted to having all my
code etc within org. I can no longer write anything without at least
one #+begin_src ... directive in my documents!
In terms of org->tj export, there were some issues (can't remember the
details now unfortunately) with default interpretation of values for
times and so on, none of which appeared to be insurmountable but I
didn't spend much time on this aspect due to the above points.
In the end, I didn't need the power of tj so found it quicker to roll
up my own!

thanks!
I should add that my longer term goal is to support some simple
critical path analysis using the table approach I have defined. This
would help me in some of the lectures on project management I give to
my students. I'm currently stuck on how to do indirect references in
org tables: how to get the contents of an entry chosen by a value in a
different entry (e.g. what is the max of the end times of the
dependencies of the current task). I've not asked any questions on
the list yet because I think most of my answers will come from
learning emacs Calc properly (so much to learn, so little time, but it
sure is fun ;-).
Thanks,
eric

This is all exciting stuff. It's a little hard to digest (many changes
rolled into one, white space formatting changes that make it hard to find
the real change, common lisp idioms which I'm not familiar with). Let me
get back to you with some questions and then we can discuss how to most
easily merge the stuff.
- Why did you compute the leafiness? I seem to have experienced that tj3
has a problem with zero effort tasks that aren't marked as milestones.
Is that the reason?
- Why do you add a duration of 1d if the task has neither a duration, an
end, a period nor an effort? Shouldn't that be a milestone instead?
- I see that there is a need to annotate a project with stuff such as
scenarios, etc and I was missing a way to have file specific reports
or other globals. Your additional tags solve that problem. However I'm
a bit reluctant to add more magic tags that mark the trees in some
way. I was hoping to find a more general way for this problem. So far
I haven't found a good solution though.
- I like the idea of the TJ drawer, but in the end you just seem to use
it for the project node and the globals node. So in essence they are
taskjuggler source code blocks (in disguise) which are tied to a
particular node. In fact they are not even really tied to a particular
node, especially in the case of the globals. This goes back to the
previous question about a good way to add file specific globals. Maybe
some kind taskjuggler specific export option is really what we are
looking for.
As an aside, I think it's better to post the source code to the list.
There might be other people interested in it and pitching in with
opinions and improvements.
Thanks

No it was more stuff like `return' and `return-from'.

OK, I understand. I managed to slowly integrate (some of) your changes.
It should now generate milestones for nodes that cannot be scheduled and
are leaf nodes. So basically it should export valid code for tj3 if you
set org-export-taskjuggler-target-version to 3.0. Of course the report
definitions in the defcustom org-export-taskjuggler-default-reports are
not compatible with tj3 so you will need to change these.
I have (or I guess rather had) some fondness for recursive functions, so
I re-implemented your leafiness function recursively. However I ran into
problems with max-lisp-eval-depth and it appears that recursion is not
encouraged in Emacs lisp
(http://www.gnu.org/s/emacs/manual/html_node/elisp/Compilation-Tips.html#Compilation-Tips).
So I guess it's back to iterative style.

I like the drawer stuff and will integrate it.

Absolutely, I agree.

Hm, no this is not possible right now. Why would you want to do this?
Maybe we could just mark it as a comment and make the exporter honor
comments.

I set up a repo and pushed my changes to the code there

Yes, I almost forgot. Would you mind doing that?
Thanks

Yes there is. See

The export to tj3 should basically work now. Just customize
`org-export-taskjuggler-target-version' to 3.0 and you should be set.
You still need to adapt the default reports[1], as they no longer work
with tj3.
`org-export-as-taskjuggler-and-open' needs to be adapted and also there
are some other incoming patches from Anthony Lander that I need to
integrate.
> - can I do grunt work for someone to make this happen?
Testing would help.
Thanks.
