Hi all

In theory we're developing according to agile methods here, but in
practice people still want to see the classic waterfall project plan.

So in order to create a professional looking gant and resource usage
charts I implemented an exporter from org-mode to TaskJuggler
(http://www.taskjuggler.org/). The code is attached and I'm looking for
feedback and would love to get this integrated in the org-mode
distribution.

TaskJuggler uses a text format to define projects, tasks and resources,
so it is a natural fit for org-mode. It can produce all sorts of reports
for tasks or resources in either HTML, CSV or PDF. The current version
of TaskJuggler requires KDE but the next version is implemented in Ruby
and should therefore run on any platform.

The exporter is a bit different from other exporters, such as the HTML
and LaTeX exporters for example, in that it does not export all the
nodes of a document or strictly follow the order of the nodes in the
document.

Instead the TaskJuggler exporter looks for a tree that defines the
tasks and a optionally tree that defines the resources for this
project. It then creates a TaskJuggler file based on these trees
and the attributes defined in all the nodes.

* Installation

Put the attached file into your load-path and the following line into
your ~/.emacs:

  (require 'org-taskjuggler)

The interactive functions are similar to those of the HTML and LaTeX
exporters:

M-x `org-export-as-taskjuggler'
M-x `org-export-as-taskjuggler-and-open'

* Tasks

Let's illustrate the usage with a small example. Create your tasks as
you usually do with org-mode. Assign efforts to each task using
properties (it's easiest to do this in the column view). You should end
up with something similar to the example by Peter Jones in
http://www.contextualdevelopment.com/static/artifacts/articles/2008/project-planning/project-planning.org.
Now mark the top node of your tasks with a tag named
"taskjuggler_project" (or whatever you customized
`org-export-taskjuggler-project-tag' to). You are now ready to export
the project plan with `org-export-as-taskjuggler-and-open' which will
export the project plan and open a gant chart in TaskJugglerUI.

* Resources

Next you can define resources and assign those to work on specific
tasks. You can group your resources hierarchically. Tag the top node of
the resources with "taskjuggler_resource" (or whatever you customized
`org-export-taskjuggler-resource-tag' to). You can optionally assign an
ID to the resources (using the standard org properties commands) or you
can let the exporter generate IDs automatically (the exporter picks the
first word of the headline as the ID as long as it is unique). Using
that ID you can then allocate resources to tasks. This is again done
with the "allocate" property on the tasks. Do this in column view or
when on the task type

 C-c C-x p allocate RET <ID> RET

Once the allocations are done you can again export to TaskJuggler and
check in the Resource Allocation Graph which person is working on what
task at what time.

* Export of properties

The exporter also takes TODO state information into consideration, i.e.
if a task is marked as done it will have the corresponding attribute in
TaskJuggler ("complete 100"). Also it will export any property on a task
resource or resource node which is known to TaskJuggler, such as limits,
vacation, shift, booking, efficiency, journalentry, rate for resources
or account, start, note, duration, end, journalentry, milestone,
reference, responsible, scheduling, etc for tasks.

* Dependencies

The exporter will handle dependencies that are defined in the tasks
either with the ORDERED attribute (see TODO dependencies in the Org mode
manual) or with the BLOCKER attribute (see org-depend.el) or
alternatively with a depends attribute. Both the BLOCKER and the depends
attribute can be either "previous-sibling" or a reference to an ID which
is defined for another task in the project.

Thanks
Christian

Hi Christian, this look interesting.  Should we put this
into the contrib directory for now, or are you aiming
for the Org-mode core?

Hi Carsten

Thanks for your reply. I've been a bit stumped by the zero feedback on
the mailing list. Maybe I should have added a few screenshots of fancy
gant and resource usage charts :-).

I'm getting all the paper work for the assignments done, so I guess we
could put it into the core. I suppose this would give it more
credibility.

What more do you need for integration in the core? 

  - Patches for the Makefile and modules customization?
  - A section in the manual?

Thanks
Christian

Christian

I think this is interesting as well.

I've been trying to get back up to speed with tj, it never fit my work 
flow before.

If you had a few more example sub-trees, it would help.

How difficult would it be to add gap duration to the export?

thanks - Tracy

Hi

If you have some org-mode files which describe a project including
effort estimates (as properties) and maybe some textual dependency
description I would gladly turn them into an example.

Otherwise I can see if I can anonymize the project I'm working on.

> How difficult would it be to add gap duration to the export?

Ah, didn't think of that. Good question. Right now dependencies are
generated on export based on either ORDERED, BLOCKER or depends
properties. I guess if you had a property section as follows

    :PROPERTIES:
    :Effort:   03:00
    :BLOCKER:  posting_controller { gapduration 5d }
    :END:

the part enclosed inside {} should not be interpreted as an additional
dependency but instead as a gap duration specification. Should be
doable. I'll add it to the list.

Thanks
Christian

That would have helped big time, I guarantee it :-)

Yes, for the manual a compact section, more details can go up on Worg  
if necessary.

Christian,

I am very interested in what you have done; it's just that I have had
no time yet to play with your code and doing so properly requires a
bit of time!  I have used TJ in the past and have liked it so the
integration with org is very appealing indeed.

thanks,
eric

Hi Christian,

I'm interested in this too! I had a few teething problems but I think
I'm doing OK now. A simple org file demonstrating some of the features
is the most important thing lacking at the moment.

I encountered problems with the fact that

- I was using `org-odd-levels-only'
- the "allocate" property name is required to be lower case (unlike
  Effort)
- A Resource named with Uppercase letters will be expected to be all
  lowercase by TJ (e.g. my Alf resource below).

I've put patches corresponding to the hacks I made to solve these below.

It would also be nice if repeated invocation of
org-export-as-taskjuggler-and-open on the same project didn't spawn
multiple TJ instances (TJ v2.4.3 ubuntu).

I had a quick look at the TJ page -- it sounded as if the cross-platform
ruby version is advancing rapidly?

Here's my test file and patches.

Hi Dan

Thanks for your feedback.

I'm working on an introduction on worg. Hopefully I'll have something by
the end of this week including an example org file.

Oh, OK, I'm not using this, so there might be issues there.

That's a general problem. The exporter needs to map between org and tj
terminology. In most cases this is not a problem as the terminology
comes from tj, e.g. 'limits', 'vacation' or also 'allocate'. Here I
assume that the property in org mode is named the same and capitalized
the same as in tj. I guess this should be stated in the documentation.

In other cases where the exporter needs to map between org and tj, e.g.
for effort, but also for completeness or dependency information, the
exporter is more forgiving. Specifically in the case of Effort it does
the downcase as "Effort" is an established property on org. For
completeness information it maps the TODO state (whether it is done or
not). And dependencies are taken from the BLOCKER attribute (which is
also semi-established).

I don't know if this is a good solution. I just tried to stick to the tj
property names as close as possible and only allow different names if
those concepts and names are established in org mode under a different
terminology. Hope that clears things up a bit.

> - A Resource named with Uppercase letters will be expected to be all

Well resource names in tj have to conform to [A–Za–z0–9_], so what I did
in the exporter is look for an ID attribute in the resource or silently
generate an id from the resource headline. So if do not specify an ID
your resource Alf will be converted (and made unique) in
`org-taskjuggler-get-unique-id'. I guess this is a bit behind the users
back and also needs better documentation. In your case the resource will
be downcased to 'alf'. I have resources like "Domain Expert", which will
be converted to "domain_expert". That's why I usually add an ID property
to resources so I can easily allocate them.

> I've put patches corresponding to the hacks I made to solve these below.

Thanks for the patches. More comments below. I have an updated version
locally which also supports optional depends attributes like gapduration
and gaplength (which were requested by T Helms on the list). I hope to
publish this on a branch in the repo.

Hm, yes. Good idea. Do you have an idea how this could be done easily in
elisp?

Yes, I didn't even realize that a new version has come out as I'm still
using the old C++ Unix-only version.

Oh, OK, good catch. Does this also work if `org-odd-levels-only' is not
in use?

I'd rather have the capitalisation as closely to the tj terminology as
explained above. I'd prefer to update the documentation here.

> Always output resource names lower case

I guess this is also a documentation issue. If you know how resources
will be named (either with an ID or with
`org-taskjuggler-get-unique-id') then it should be more clear how to do
the allocations.

> More comprehensible error message if you forget to define a project...

Yes, of course. I had fixed that one already locally.

So, thanks again for the feedback. I hope to have the worg page and the
code in the branch soon so things should become clearer.

Thanks

Is this more the reponsibility of the application?  E.g. I just did
'firefox some.png' from the shell and it opened a new tab in a running
process. So maybe it's a question of checking whether / requesting that
the new ruby implementation has a way of telling it from the shell to
open (update?) a project in an already-running TJ process.

Yes. C-h f org-heading-components says the second element differs from
the first only if org-odd-levels-only is set.

One note on this... I think only the new Ruby version (TJ3) supports an
actual gantt chart export... 2.4.3 (or whatever the other version is at
right now) only shows a gantt chart in the program itself if I recall
correction. It's not until TJ3 that you can get nice html output without
needing the QT-based interface.

Perhaps not a huge deal for some, but I really wanted this (gantt charts)
and did not want to be stuck with the QT interface for exporting them (or
even showing them to others). If this is the type of output being sought,
I'd stick with looking into TJ3 org-mode integration over 2.4. Or perhaps
take a look at the first of the references on how to use both: TJ 2.4 for
viewing and TJ3 for exporting?


Best regards,
John

The exporter is pretty agnostic towards either tj3 or tj2.4. It pretty
much just exports the properties you define in your nodes. It also does
some magic with regards to dependecy and resource export, but these have
not changed in tj3. While I haven't tested it with tj3 the export from
an org file should also work for tj3. You might have to tweak the
reports some, but this can be done with the customize interface.

I finally managed to push the taskjuggler exporter to the public repo.
It's located in the branch taskjuggler-export and should be ready to be
merged into the mainline.

- All the FSF paper work has been completed
- AFAIK all the feedback has been incorporated
  - e.g. frivolous handling of ID property
  - better error handling
- added documentation to export section of org.texi
- included taskjuggler export in the export dispatcher
- added it to the Makefile

I'm using this exporter almost on a daily bases, but I'm sure there are
quite a few issues left. For example there is a warning when byte
compiling about a reference to free variable `old-level'. I don't know
if it is kosher to just quiet the compiler with a defvar. There are some
other known issues mentioned in the TODO section in the code. However I
think it is ready for wider consumption.

Also there is an up-to-date tutorial on the usage of the taskjuggler
exporter at http://orgmode.org/worg/org-tutorials/org-taskjuggler.php

Thanks
Christian

Hi Christian,

looks great, but I get a few compiler warnings:

I have already merged and pushed your branch into the master, but please
make a patch that fixes these minor issues.

Thank you very much for this great contribution!

This I cannot reproduce using the command command you gave. Is this
maybe only a problem in newer Emacs versions? I'm using Emacs 23.1.1

Digging some more I found the following in

i.e. Emacs 23.2 has a different api for start-process-shell-command.

I'm not quite sure how to deal with this. Should I add a wrapper
function in org-compat (say "org-start-process-shell-command") that
checks for emacs version > 23.2 and calls start-process-shell-command
accordingly?

One possibility is to check for versions.  Better is maybe to do it  
like this

(condition-case nil
    (org-no-warnings
      (start-process-shell-command with four different args))
   (error
    (start-process-shell-command with three args))

Thill try one version, and if that given an error, try the other one.
To get rid of the compiler warning, wrap the call into org-no-warnings.

I suppose old-level is a let-bound dynamic variable. I have found code
giving a seemingly global variable name to such variables confusing at
times. Would be better just make it global or insert a form at the
beginning of the body of those functions like this:

(declare (special dynvar1 dynvar2 ...))

I usually use the latter approach.

Cheers.
