325137 - Should be possible to print tasks

Status: RESOLVED FIXED

(Calendar :: Printing, defect)

Description

[Stefan Sitter [:ssitter]]

When clicking into the task list the Print command toolbar button and the Print menu entry are disabled. This is done in
http://lxr.mozilla.org/mozilla/source/calendar/resources/content/unifinderToDo.js#237
http://lxr.mozilla.org/mozilla/source/calendar/resources/content/unifinderToDo.js#245

But there is no code to enable the Print command if you select the views or the event list or ... Thus the Print command stays disabled until program restart.

Attachment: task-list printing

After removing the disabling code, I realized that we probably should offer some similar way to print tasks.  This patch introduces a second category of print-formatters, one designed for tasks.  (Note that the month-grid printer can be registered in both categories.)  It also implements a version of the hCalendar exporter for tasks.  I could not find a standard definition of what to do with VTODOs, so I improvised a bit.

Attachment: real patch

There were a couple of small proof-reading changes that didn't make it into the previous patch.  This is the real thing.

Comment 3

[Michiel van Leeuwen (email: mvl+moz@)]

This patch looks like a copy of the current html printer. Three questions come to mind:
Can this be structured just like the event list printer, so that you can also export the task list?
Why use a different filename scheme? (-Printer instead of -Formatter)
Is there a way to unify more code?

The rest of this patch looks ok (but I didn't test yet)

It can, however, a couple of issues come to mind.  1.) We don't have a clear picture of what printing options we want to expose and how to expose them.  2.) The hCalendar spec I was looking at only described VEVENTs, I didn't know if there was a spec I was supposed to work off of for VTODO, or whether I would be violating the spec by including the VTODO data.

> Why use a different filename scheme? (-Printer instead of -Formatter)
Because I only wrote it thinking of printing, not exporting.  If we want to do export too (where we again need to consider how we're going to expose options), then I agree it should be called Formatter.
> Is there a way to unify more code?
That depends on the answers to the above questions.

That doesn't take away the fact that we can prepare the backend code to already allow exporting. The front-end can come later. And if we do it the right way now, we don't have to rename files etc then.

> 2.) The hCalendar spec I was looking at only described VEVENTs,

If it isn't in the hCalendar spec, we just invented a new spec, called hTodo. Really, hCalendar looked flexible enough. And I really don't see how adding some  class names will hurt anything. We just need to make sure the resulting hTodo block is different enough from a hEvent block to bot be confused.

Comment 7

[Joey Minta]

I'd like to get UI-Review on the way we differentiate between printing events and tasks here before pressing forward with this patch.

Comment 8

[Stefan Sitter [:ssitter]]

Just for the notes: The intention of this bug was not to disable the print command. I think that is all that needs to be fixed for 0.3. Printing of tasks is something that can be solved after 0.3 in my opinion.

Comment 9

[Dan Mosedale (:dmosedale, :dmose)]

This bug seems to have morphed into "we should be able to print todos", which we've agreed entrains some UI discussion and therefore shouldn't block 0.3.  However, the bug as filed probably should block 0.3.  In recognition of the fact that most of the discussion in this bug centers around printing todos, I'm gonna spin off the "Print command disabled" to a separate bug.

real patch

This patch has bitrotted. More importantly, I do not believe that we should have a separate "print tasks" command, so I disagree with the architecture of the patch. I think that the ability to print tasks as well as events on one page would be desireable, especially if the user has the "show tasks in view" option set.  I think that a better solution can be created that better melds events with tasks under the guise of one Print command with several different layouts.  For example, perhaps a weekly printing of events with a task list in a column on the right side of the printout.

Sorry, but I feel this needs more work.

Comment 18

[Mike Freeman]

I'd like to toss in a comment on this topic. The ability to print tasks as an independent item is crucial to the task pane being usable. In most organizations I have worked, people use the tasks as mini-project trackers: i.e., more than just 'remember to do this' reminders. For example, I may create a task to track crucial events of a products introduction and periodically update the detail of the task based on events, (i.e. the task is the master item with events being subservient to the task) but need the ability to print the task either individually, or at least print all tasks at once with each task on a different page. Also, I will attach the task to emails to circulate for updates. Just my two cents, as this one item is keeping me from ditching Outlook altogether. Thx, Mike

Comment 19

[Verle Keszler]

(In reply to comment #18)
I have to agree - for business use, tracking individual tasks/assignments is very useful, but without the ability to print these tasks, the usefulness of Sunbird is very reduced in my mind.  Additionally, for personal use, I believe many people use tasks as home to-do lists, and my wife would even like to use it as a place to make and update shopping lists, so again, printing should be included for tasks.

Comment 20

[Rubén Martín [:Nukeador] ❌ [away till Aug 31st]]

We are having several reports in our community forums about this issue, is somebody working on it?

Comment 21

[Andrew]

I have never downloaded and installed a patch so I would be unsure exactly how I would do this. I would hope that it would be a completely automated process, just download, press the install button restart Thunderbird and it will work perfectly first time. I can print tasks now but it is a bit fiddly, all you need to do is hold down the ctrl key and click on the Tasks that you wish to print, then go ctrl-p and the print dialogue box box appears, and in the "What to Print" box check "Selected Events" the tasks that have been selected will appear in the print preview. This method does work although there is no scope to format what is being printed, I think that I will stick with this method until I can be sure that I will not totally mess things up with by trying to install a patch. It would be better if you could just download it as an update.

Comment 22

[Mike Freeman]

I just wanted to add another note to this. I am using Thunderbird 2.0.0.16 with Lightning nightly updates installed. As of the September 9 update, the "Print selected events" is still grayed out and cannot be selected. It has been this way for a long time. The ability to print tasks is critical to the task function being used effectively, as many users utilize a task as a mini-project list.

Comment 23

[Thomas D. (:thomas8)]

Is anyone working on this? This bug renders the whole application useless for me.

Comment 24

[Al Starr]

Requested feature when "printing tasks" is added to Lightning/Sunbird:
When printing tasks within a user-specified data range, it is highly desirable to offer an option to print the recurrence pattern rather than just an indication that it is recurring.  For example:  "Occurs the first Sunday of November, effective 11/4/2007".

Comment 25

[Simon Paquet [:sipaq]]

Nominating for blocking1.0.

IMO, printing out a daily, weekly or monthly schedule is a key requirement for a 1.0 release. That schedule encompasses your current tasks in my view.

Comment 26

[mike]

I do absolutly agree with this statement. Printing tasks is a basic need.

Comment 27

[Philipp Kewisch [:Fallen][📱📆]]

Although I agree that printing is a quite basic need, unless we have more developers to work on this it won't happen for 1.0. Printing is not an area of focus for the current release.

Comment 28

[james]

"Printing is not an area of focus for the current release."  For a 1.0 release?  Kidding right?  *sigh*

Comment 29

[Andrew]

Isn't it about time that this problem was fixed once and for all? I realize that it is been done by volunteers but it has been ongoing for years, I would like to click the update button then install updates and find that I am able to print 'Tasks' and the results look like a page from a business diary like in MS OutLook.

Comment 31

[Philipp Kewisch [:Fallen][📱📆]]

This might make a nice student project. Our printing support in general is very primative, depending on the amount of time the student has, he or she may also like to fix a few bugs related to printing events in the current format, or even create new formats.

A group of three students from Brazil in a course about open source is going to be working on this bug as a student-project. Looking forward to your patch(es), thanks Eduardo!

Comment 33

[Sven Giermann]

Attachment: AddOn for Lightning 0.8/0.9 to support printing of tasks

I just wrote an AddOn to support printing of tasks by overriding "getEventsAndDialogSettings()", as outlined in attachment 216283 [details] [diff] [review].

I chose to not differ between 2 print Menu items, but to provide printing of tasks in MonthGrid and WeekGrid. As the current implementation "List" is not capable of printing tasks without Start date or Due date, I included a fourth print layout "tasks".

This is only a workaround for people waiting too long for this and offers only a simple list. Also the wording is not optimal, but I wanted to use only existing strings to support all locales.

Furthermore it could be modified to work with Sunbird as well, but I don't need this. It would only require to change INSTALL.RDF to include Sunbird, but needs to remove Lightning requirement.

[Sven Giermann]

Attachment: Fix loop through sorted list for Week and Month Grid Printer

Decathlon pointed out a problem with the existing Week and Month Grid Printers - they sort all tasks before events, but then break whenever a start date is higher than the current day.

This wipes out all events that are before the last task's start day.
The attached patch would just continue on tasks and only break on the first event after the current day.

[Sven Giermann]

Attachment: WIP patch to print a simple task list and tasks in Week and Month Grid

I preferred to upload my WIP patch for everyone here.

I payed attention to Comment #3 and Comment #12, therefore obsoleting attachment #216283 [details] [diff] [review].

This is a very early WIP, but already working in production on my site. The locales should be replaced by new ones (rather then stealing from different dialogs) and there is still one issue outstanding:

* I did not try to get any selected Tasks - I'm happy with disabling this with the "task list" layout.

But since the core code of the effected files did not change since version 0.9, it should also work fine with current nightly builds (I did only check with 0.5, 0.8 and 0.9 - but 0.5 misses some of my stolen locales and handles completed tasks differently).

patch to print tasks 

Hello Eduardo and Friends,

sorry for the delay, I've had real life things to do. First of all I'd like to thank you for the effort you have put into this. I'm confident we can have this patch go into the next beta of Lightning. The current beta won't work since strings are changed and we are already in string freeze.


First of all, I'd like to give you a code level review. I'm sorry if you feel this is being picky, but to keep the code readable its necessary to make sure that all code follows the same standards. We have a few hints on https://wiki.mozilla.org/Calendar:Style_Guide that might help you, but I've marked most nits here.

As a next step, I will be testing your patch. I hope to get to that soon, maybe this weekend, otherwise starting next week. Then I'll give you another round of comments and I'm sure we will come to a positive review soon after that.

It seems you use this function more than once. Instead of copying it, I'd prefer to keep it somewhere common and just call it from each location. Correct me if I'm wrong though.

This needs to be tested, but I think the print stuff is happening from "content", so you might need to add the css file to a package that has contentaccessible=yes. I'll double check this in the next round of review.



I'm marking your patch as "r-" for now, which means review was denied. This isn't meant personally, I'd just like to see a new patch with nits fixed and possibly also with the upcoming test review comments fixed.


Sven, are you going to continue working on your patch? I really would like to avoid double work, so please collaborate on this (!) and let me know what the outcome is.

Comment 41

[Sven Giermann]

Philipp,

I was in contact with Eduardo to avoid double work. I did not reassign this bug at the time of writing the patches - I only uploaded them to share my code...
I stopped working on this after having a quick & dirty solution for my users issue - I believe Eduardo will give a much cleaner and time consuming solution here!

It's not your fault, but reading Philipp's comment 40, all of the names (existing and new ones) should be aligned under the "n" of "Contributors", as I'll show in the correction of the following code:

> # Contributor(s): ArentJan Banck <[e-mail]>

Same as above (not your fault), but all the names should be aligned like this:

# Contributor(s):
#   ArentJan Banck <[e-mail]>
#   Eric Belhaire <[e-mail]>
[etc.]

These are all very small details, but maybe by fixing the style we can lure Philipp into reviewing the code ;)

Sven, I'm not trying to pass the buck to someone else, I'm sorry if my comments give this impression. I do want to see this fixed and I'm happy to concentrate more on the functional aspects, but to do that I need all files to do the testing.

Could you summarize the functional issues that are still open for discussion? I seem to be missing them due to all of my style comments.

Comment 54

[Philipp Kewisch [:Fallen][📱📆]]

Attachment: Combined Patch

I've debitrotted the patch and added calendar-printing.css from the next to last version. The patch works and provides Task printing capabilities as expected. A few points we should look into:

Things I think should be taken care in this bug:

* In the Weekly/Monthly Planer, its possible to check/uncheck the Tasks without due date. I'd suggest to catch the clicks and not let the user change this, since its the preview. Check out the XUL allowevents attribute. If that doesn't work, you may need to add an event listener that stops propagation.

* In the list view, completed tasks are not distinguishable from not completed tasks. I'd suggest the line-through style, or a label (i.e:  a new task (completed))

* It would be nice if you could change the background color for the print preview to white, since the paper will be white too. I'm fine with postponing it to a different bug, but it would be nice to take care here.

Things I think can be taken care of in a different bug (you don't have to fix these yourself, if you don't want to):

* In the list view, tasks without start or due date are specifically labeled as such (in the "When" section). I think we should just drop the "When" section in this case.

* Tasks with the same start and due date are shown as:
   [ 02:00 PM-02:00 PM a new task ]
  If possible I'd prefer just showing:
   [ 02:00 PM a new task ]

* Some other task properties (i.e progress, category, ...) are not shown in the print view.

What do you think? Does this sound reasonable?

Sure, I'm gonna work on the three first ones. When I finish this, I can work on the laters.

Hello, any problem if I just disable the checkbox? Is it better to do the above?

I believe if you just disable the checkbox, it looks gray. I'd prefer a normal looking checkbox that is just not clickable. Go ahead and test it though, it may work.

New patch with calendar-printing.css

The code for this patch looks great, it would have r+. Removing review request to wait for a patch with the mentioned functional issues.

Comment 61

[Eduardo Katayama]

Attachment: New patch

Updated:
-> I just disabled the checkbox to test, if you think it needs to be a normal checkbox that is not clickable, just tell me that I will fix it :)
-> In the list view, completed tasks are distinguishable from not completed tasks. (Added a label. i.e:  a new task (completed))
-> Changed the background color for the print preview to white.
-> In the list view, tasks without start and due date dont have a "When" section.
-> Tasks with the same start and due date are shown as: [ 02:00 PM a new task ]

Any idea, about how the task properties should be shown?

I would prefer a disabled checkbox (as it is now), just to prevent user's calls "Why doesn't this checkbox accept to be checked?"

> Any idea, about how the task properties should be shown?
How do they display now? Any screenshot?

I think it shows title, description, location, date.
I just uploaded a print preview :)

Comment 65

[Thomas D. (:thomas8)]

Eduardo, thanks for the patience and diligence with which you work on this bug. It will be a great improvement when it lands.

Looking at the current preview (screenshot attachment 435810 [details]), some thoughts:
1) We could save a lot of space (i.e. printout length, paper, and trees...) with a small re-arrangement of the properties. We currently have:

/When/
  When-property
/Location/
  Location-property
/Description/
  Description-property

Re-arranging this into a tabular structure will produce a much more compact printout in many cases, especially when we add more properties as suggested by Philipp's comment 54:

/When:/        When-property
/Location:/    Location-property
/Category:/    Category-property
/Status:/      Status-properties (inkl. % completed)
/Repeat:/      Repeat-property
/Description:/ Description-property

Eduardo, would this be a difficult change? Of course, we should only print properties whose value has been set/changed by user, so e.g. if category is "none", just skip the category-property altogether, as you already do for the when-property.

Benefit of tabular structure: For most cases (with short property-values), we're saving one printed line per property. That's saving up to 6 lines or more per task if all properties are defined. For a lot of cases (property-values of up to ca. 1.6 lines), we're not loosing printed space compared to the current layout. For a few cases (property-values of more than 1.6 lines), we loose a small percentage of space compared to the current layout (e.g. for every 5 lines property-length, we loose one line because of the tabular structure).

Philipp, do you think that we should print Calendar-property and Reminder-property as well? I'm not sure. In the long run, we'll need a way of customizing which properties should be printed or not. But that's surely beyond the scope of this bug. I'd propose to skip Calendar and Reminder for printout until such time that we'll have customizable printout. Otherwise, some people might go mad that we print a full line per task for Calendar-property where they might only have one calendar, or be printing just one calendar out of many.

Comment 67

[Philipp Kewisch [:Fallen][📱📆]]

I'll comment more elaborately later, but unless its not too much work, I think its sensible to move the change to a tabular layout to a different bug. I'd like to get this fixed soon so we at least have the basics :-)

Comment 68

[Philipp Kewisch [:Fallen][📱📆]]

I'm about ready to take this patch! I've done some testing and it (almost) seems to work as expected. I have one issue: I can't get the dialog to show completed tasks, regardless of what state the "Completed tasks" checkbox has.

I couldn't quite find out the reason, the code itself looks like it should work. I'll do some further testing, if I find out its a local issue I'll r+ the patch.

Comment on attachment 435607 [details] [diff] [review]
New patch

Turns out to be a local issue, some of my tasks were not being returned in the getItems calls. No idea why this was happening, it works for all tasks newly marked as completed.

To speed up things, I've fixed all the following issues locally, so you don't need to do any further steps. I will check this in soon (probably today).

>+function getFilter(settings) {
>+    let filter = "";
filter should be an integer

>+        if (settings.printCompletedTasks)
>+            filter |= Components.interfaces.calICalendar.ITEM_FILTER_COMPLETED_ALL;
>+        else
>+            filter |= Components.interfaces.calICalendar.ITEM_FILTER_COMPLETED_NO;
Add {}'s here

>+
>+EXPORTED_SYMBOLS = ["utils"];
>+let utils = {
We should rather use the cal. namespace prefix here, as other extensions may also easily use "utils.". I also think we should rename this file to calPrintUtils.jsm, since the function is rather print related.


>+    getTasksWithoutDueDate: function getTasksWithoutDueDate(aItems, date, calGetString) {
Why do you need to pass calGetString here? We can just take this from calUtils. This function also has indentation issues and needs a convert var->let.

>-                <div class='value summary'>{item.title}</div>
>+                <div class='value summary'>{item.isCompleted ? item.title + " (completed)" : item.title}</div>
Since this is user-visible, it needs to be localized.

>+
>+        function isTasksWithStartOrDueDate(startDate, endDate) {
>+            return (startDate != null || endDate != null);
>+        }
>+
>+        if (isTasksWithStartOrDueDate(startDate, endDate)) {
Since this is the only location you use the closure function, you can directly use the condition and add a comment.

Looks like your editor is not saving in utf8, please fix for the next patches.

Comment 72

[Damian Szczepanik]

could not print task when:

1. create task with start and due date
2. from menu select "tasks in view"
 -> new created task is visible in view
3. go to menu file -> print
 -> in preview all events (from the same date as task) are visible but task is not printed
4. try to print out anyway
  -> task is not printed, only events are

I think not. We still need to file followup bugs.
