Yeah, avoid where possible. I don't think there's need for anything except some notes for *most* items. It might be useful later down the line for reporting capabilities. Show me all dives where I used my Buddy BCD etc. I got your point and I also would love to have more comments about it. But as I mentioned above, it would not be hard to know that a specific equipment requires specific fields - so it would work fine anyway, in addition, it seems to be much more consistent (all equipment following the same structure). So perhaps we go along the line of including cylinders, see what the implementation looks like, and we could revert to the existing system if we need to. Also think about migration of existing Cylinder/weights/suit data. Yeah, it's also very important to have existing logs working fine with this new feature. I have summarized some of the main GUI aspects below. Please, let me know if I'm in the right track (or not - what's wrong?) I don't know if users and developers are happy with the idea of having a grid view. But it seems that the right thing to do is to start the project using table views. Then, we could work to implement the grid_view... so users could be able to switch between views (table or grid)... (?) -- Graphical User Interface We will need to have two different GUI. “Asset Manager”, where the user will handle all their inventory and the “Equipment tab”, which will show the equipment took on a dive. - Asset Manager In the Asset Manager panel we will show all pieces of equipment. The users would be able to add new items and edit their key properties, including adding a photo of the equipment if it is desired. Users could also keep track of when an equipment was last serviced, and when it is due. This is also a great place to keep track of which elements were used on a particular dive, and when it needs to be serviced. Some kinds of equipment can have an extra field to store a specific data, which can be set to a default value. These fields can be edited directly in the “Equipment tab”. Users should be able to sort items by name, manufacturer or type. Users should be able to create new groups of items. -- Asset Manager :: grid view It would looks like the “MacDive” view (please, see screenshot above), where we would have all items and groups being displayed in a grid. It could be implemented using QListWidgets [2] - they have drag and drop events and it wouldn't be hard to get it working over QListWidgets (eg. from equipment_view to group_view). #1) how to add an equipment a1 - double click in a white space OR a2 - context menu - ‘add equipment’ b - dialog box appear - then, user can fill the fields and save [*] c - new equipment will be displayed on the grid [*] this could be a new window or a “bottom panel” (insed the Asset Manager dialog) #2) how to edit an equipment a1 - double click the equipment OR a2 - context menu - ‘edit equipment’ b - dialog appear - (save as #1) #3) how to remove an equipment a - context menu - ‘remove equipment’ b - it is being used somewhere? b1 : b2; b1 - warning - it cannot be removed - do you want to disable this item? b2 - remove item #4.1) how to create a group a - select equipments (one or more) b - context menu - ‘create group’ c - type the groups name d - the group appear in the ‘groups grid view’ #4.2) how to create a group a - open context menu in the ‘groups grid view’ - ‘create group’ b - type the groups name c - the group appear in the ‘groups grid view’ #5) how to add items in a group a - drag and drop item in the group #6) how to add items in a group a1 - double click the group OR a2 - context menu - ‘edit group’ b - dialog box appear (it will contains only two things - field with groups name + simple table view with ‘name|manufacturer|type|checkbox’) c - selected items will be in the current group... -- Asset Manager :: table view We could have two table views: ‘equipment_table_view’ and ‘groups_table_view’. They could be placed side by side as well. Users should be able to choose (checkbox) which columns they wanna see. It is a simpler model. In this case we could display all data in columns - where users could edit them directly in the table (exactly as we are doing now with cylinders and weights). ‘equipment_table_view’ As discussed above, some equipment could require specific fields - in this case we could use a dialog box OR a “bottom panel” - as it was suggested in the grid_view above…

Re: GSoC 2015 - Introduction
*MANY* thanks for your powerful explanation. =D
You're welcome :)
I have many ideas about how it should looks like and work... I'm doing
some mockups and I will let you see it soon.
Great, I'd love to see them.
I'm thinking about structures where users could add or/and group things by
a simple drag and drop
That sounds good. The specification uses the word groups, but I don't
really like this because groups seems to imply that an item belongs to a
single group. I prefer sets. My Suunto dive computer, for example would
be part of both my UK Cold Water set, and my Tropical set, as I use it
wherever I go.
- we could have a view or dialog with all equipments
- users would be able to 'drag and drop' items from this view/dialog to
the equipment tab
... and drag and drop complete sets too. Yes.
- I think it's important to have pre-defined categories - easier to find
items
I think some sort of structure would make sense, but I'm finding it hard to
imagine categories with the right granularity. I could see most categories
containing just a single item (or perhaps a choice of 2):
Lighting:
- NDiver X3 Torch
- Umbilical HID
Emergency
- Strobe
- Whistle
- Diver Alert
Breathing Gear
- Regs
- Cylinder
- Guage/Console
Maybe something like that could work. This could perhaps use some input
from some of the more experienced/techy divers.
- It would be nice if each category had a thumbnail - it could be
configurable (eg. allow users to add a picture to a specific equipment,
otherwise just use a default img of the corresponding category)
- equipment tab : instead of showing a detailed list, we could show a kind
of thumbnails list with very basic info (name + manufacturer + number of
uses) - tooltip-more info - double click-dialog with details
For the equipment tab, I would simply go for something like
{Manufacturer}: {Name}, and probably just in a straight list, or possibly
switchable between a list and thumbnails. I think that function needs to
win over form here, but would like to hear input from others.

Hmm... it would be just a case of naming - the base idea is to have
exactly what you expect = one equipment can belongs to none, one or many
groups/sets =D
- we could have a view or dialog with all equipments

Maybe something like that could work. This could perhaps use some input

Maybe the name should be 'type' instead of 'category'.
In this way, I think that it would not be a problem if we identify/name
each equipment according to what it is...
eg. http://iesa-fao.org/wp-content/uploads/2014/02/Scuba-Gear.jpg ,
http://www.scuba.com
what do you think?
- It would be nice if each category had a thumbnail - it could be

Yeah, I'm considering the idea of having two ways to display the data -
detailed list OR thumbnail list
I was doing a research in other software (in order to see how they handle
this kind of thing). I saw that MacDive has something like what I had in
mind for a thumbnail list.
http://www.mac-dive.com/images/features/feature_gear.png
Unfortunately I'm not a MAC user and I'm not able to install it and see how
they do to add an equipment in a divelog - someone knows?
Another aspect to consider it that a type of equipment can have a specific
key property on a dive (which will be set only in the equipment tab on a
dive, of course) - eg. cylinders and weights
So, the equipment list would display only basic info (which are common to
all equipment - user should be able to choose what columns they want to see
in a list as well).
Now I'm imagine how the user would set the parameters of a 'cylinder' in
the equipment tab:
1) double click - open small dialog box with these fields (pop-up)
2) single click - a kind of accordion effect, fields appear (sliding) in
the bottom of the equipment tab (users should be able to stick this small
side panel if they want - so, it would not be shrinking and stretching
other fields in the equipment tab every time something is clicked)
3) ideas?
Actually I would like to avoid 'extra windows' as much as possible, because
I think that there is nothing more annoying than a new dialog box
popping-up as a new window for every single feature...

Ok, so something like Weights - 4kg Yeah, i can see that working. One might even want to include defaults for those key properties when including an item in a group/set. So, my weights for Tropical would be 5kg and my weights for UK Cold water would be 12kg, but I might then also change them on a per-dive basis. nice hint! =D I will include it, thanks My only reservation is about including cylinders in the whole asset management stuff. Cylinders are equipment, yes, but they also contain a mix, and that stuff is important for the profile and deco planning. I have a gut feeling that cylinders and mixes should remain independent of the whole asset management thing. Would love some input from more experienced divers on that. I got your point and I also would love to have more comments about it.

Re: GSoC 2015 - Introduction
Hi Marcos, *- Asset Management* The main concept of this project is very clear[2], but as I'm not a diver, I really appreciate your help to better understand all the details expected for this project. In this way I would have more knowledge to think about the data structure. Do you recommend any specific documentation/software which would give me ideas about what would be expected from the user point of view (I mean, assets)? I think this is made up of 2 parts, which are very closely linked. Inventory management, and Equipment used on a dive. I think the best place to start with this is to look at the equipment tab for the dive. This currently allows the diver to record and track the use of 2 pieces of equipment used on dives. 1) Cylinders and 2) Weights. Weights are simply recorded, cylinders can also used for gas changes, which forms part of various calculations (this is for advanced tech diving where different gas mixes are used for different portions of the dive). The only other item of equipment which is discretely tracked is 'suit' which is on the Dive notes tab. Lots of divers also like to track other pieces of equipment - they might like to look back when was the last time they used split fins, or what thickness hood did they use on that ice dive last year. We simply want to be able to be able to track all of the equipment we used on a dive. Now, for many dives, divers will use exactly the same set of equipment. You find the thing that works well for you, and stick with it. The diver doesn't want to have to log 20 pieces of equipment for each dive, when they are almost always the same. This is where equipment 'groups' come into play. I diver might have a set of gear which he typically uses in cold water. A drysuit, fins which fit over drysuit boots, maybe twin cylinders, a heavier set of weights to account for the bulk, a 7mm hood, gloves, etc. That same diver, when travelling to the Red Sea, might use a completely different set of gear. A 3:2mm shorty wetsuit, full foot fins, hired 12l single cylinder, no gloves/hood. An advanced user might want to split this down further, depending on different combinations of usage. They might have 2 different groups of 'breathing gear' (eg Open circuit gear, AP Rebreather), and 2 groups of 'climate gear' (UK Cold water, Tropical). So it should be possible to select more than one equipment group for a single dive (e.g. AP Rebreather + UK Cold water). As well as being able to select multiple groups, it should also be possible to select additional individual pieces of equipment, which might be occasionally taken on dives, depending on circumstances, and finally once equipment sets have been selected for a dive, a diver might want to change specific pieces of equipment for a single dive only. So maybe the diver has selected UK Cold water set, but on that dive actually decided to try out a different set of fins... it should be possible to edit the individual pieces for that dive, and only that dive. This last point is an interesting one, implementation wise. You might find that the groups are only used to build the equipment profile for a dive, and are not stored as part of that dive. Equipment groups will change over time... switching a piece of equipment in a group should only affect new dives logged, and all previous dives should remember exactly what equipment was used at the time. I hope that gives some of the inspiration for this project. I think if you have any further questions relating to the 'diver' perspective of this functionality, just ask away. Would you expect to have the data being stored in the same log file (xml)? Absolutely. You probably want to be looking at 2 places to store data in the file. 1) At root level, which stores the diver's current inventory, and equipment groupings. 2) Equipment used on each dive, stored along with the data for that dive. Do you expect to have it placed as a new view or a new dialog? I'd like to see proposals for this. For the per-dive data, I think the Equipment tab is probably the right place for this to live. For the inventory management, I imagine a separate dialog, opened from the pull down menu, would be consistent with the way things work. Again, I'd like to see proposals, and maybe other users have some input on this. - Any of these projects have a higher priority? I think that the answer for this one will be 'NO' - but, as I'm considering these two projects, it would be awesome to hear from the community which one would make more people happy! =D I'm not a real evangelist for user testing, and I'm primarily a user rather than a developer, so I'd be much happier to see real functionality over better test coverage. However, I'm sure opinions would differ on this. http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface Cheers Martin ___ subsurface mailing list subsurface@subsurface-divelog.org

They should be visualized on the UI. iam capable of coding this project as i have - C / C++ / Qt5 - understanding of data structures and data relationships CONTRIBUTION FROM ME: iam a very curious student eager to learn new things n highly talented in coding skills and iam participating in GSOC 2015 for the 1st time n iam very much interested in coding for ur project. 1. read through the documentation. watched the video and understood how subsurface works 2. installed subsurface on windows and played around with it. cloned the repo in a fedora vm built it from the code using instructions given 3. looked at some bugs THE PROJECT - i want to acieve the accomplishment of coding for Design of the data structures used, the UI to manage and assign items to a dive, the storage format for the different supported storage backends. i will do this together with the developers, taking their input and requirements into account.

To me that is the far superior idea as it allows us to completely control the interaction with the user without having to wait for libdivecomputer API changes. Only if QtBt is still too limited to implement what we need (which I doubt) do I think we should try to add OS specific implementations to libdivecomputer. /D ___ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface

Gehad, your application is very well formed.
other students can take this into account when they write their own
applications.
here are some entry level notes and questions that will emphasize on
eventual topics of interest for the *actual* user base.
Pre Existing layouts technical information
● Supported Paper size : A4 – A5
● Supported Quality : 300 dpi
● Supported Orientation : Portrait
we need to extract settings from the QPrinterDialog and from the user
configuration QSettings and adjust the CSS .media related sections
before the pagination.
i'm pretty sure this is doable.
My intention was to extract the settings from the QPrintDialog and
save the user preferences as QSettings, but I think we have to put
some constraints on the resolution (page size and Dpi ) and the page
orientation to produce good quality templates that are able to make
use of the paper area, for sure this constraints can be extended by
writing additional templates, so I think this constraints are on the
templates I am planing to develop in the scope of the project only.
i don't think the page size should be hardcoded per template or
constrained (as long as the dimensions don't reach the 32bit integer
cap or something like that).
from my tests if i simply modify the CSS the resulted pages were exact
fit to a certain page size (e.g. A2 ) when printed and the HTML layout
adapted quite well.
the available space for a page in QPrinter is just numbers, you *can*
adapt your layout to fit on it. the current printer implementation
does exactly that.
say, if the CSS is in a QString after the user has made his picks, we
can search-and-replace certain variables.
for instance like SSRF_PAGE_W, SSRF_PAGE_H, SSRF_MARGIN:
@page {
size: SSRF_PAGE_W SSRF_PAGE_H;
margin: SSRF_MARGIN;
}
for A4:
SSRF_PAGE_W becomes 21cm
SSRF_PAGE_H becomes 29.7cm
(for landscape the reverse happens.)
SSRF_MARGIN becomes for instance 1cm
...or instead of these variables, we can keep some default values so
that the CSS is not invalid and do some smarter search-and-replace.
only once the CSS is adapted to the user preferences we feed it to the
HTML, load the HTML in QWebView and render it.
do you see any problems with these ideas?
No, I ll add this into the proposal, thanks for the clarification.
I also wanted to suggest the idea of printing dive photos may be on
glossy paper, I don't know if this use-case may be interesting to
someone?

The application can be found on [1] link. I didn't write it in this e-mail because I was afraid that it will lose the format. hello, the application proposal is rather short, but then again this is a rather technical topic and there isn't much to say. though, it does hint that you are knowledgeable of the topic. but we need to make some decisions first... we need to decide if Qt BT is the way to go. BlueZ and the Microsoft stack are essentially already used in Qt BT, and Qt BT also supports OSX which we are interested in. in the other thread we have discussed libDC vs Qt BT, and my personal opinion is that Subsurface is not the place for Bluetooth stack implementations - libdivecomputer is. Qt BT can be integrated as an optional layer in Subsurface and the libDC parser can be fed raw data, but the problem is that the parser demands some low level device info (as far as i understood from Jeff). not up to me to decide, but i don't see the need to use BlueZ and the MS Stack at all - the BT module in Subsurface can be based on Qt and eventually libDC can support the same functionality which will make the module obsolete. once the decisions are made you can update the application. also it would be much better if you provide some simple code / module organization details (classes, files, callbacks, etc) and perhaps a simple block diagram. thanks lubomir -- ___ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface

do you see any problems with these ideas?
Figure(3.1) Printing block diagram
the graph looks good. if can you visualize what i mean by the above
comment about QPrinterDialog, basically the CSS / HTML will be fed
(e.g. with search-and-replace amends) with stored settings in the user
configuration (from QSettings) and also with on-the-spot configuration
such as margins, orientation etc. from the QPrinterDialog, then
QPrinter will receive the rendered result as a paint device.
Yes, I think Grantlee can take care of that. I will add this to the
block diagram.
related to the commend from above.
Rendering the QWebView will take place by scrolling the QPainter viewport
over the
whole content as shown in Figure(3.2)
hmm, when i experimented with a paginated CSS template there was no
need to scroll the viewport and QWebView simply, magically paginated
my pages with render().
i may be missing something, but if you think that the viewport
rendering is better i'm glad to hear why?
When I use QWebFrame::render() I got the first page only rendered so I
used QWebFrame::scroll() , anyway I didn't test this well I will have
a deeper look into this.
my mistake; i've used:
someWebView-print(somePrinter);
and it printed all pages, but i'm not sure if this is the way to go as
it prints directly, while we also need to overlay the profiles.
render(), scroll() and a viewport might be the way to go.
Template options
the 3 tabs cover what is required pretty much.
how do you plan to generate the previews BTW e.g. QWebView rendering
some sort of default contents on a QPixmap that is placed in the
dialog?
I think the QWebView will render the actual HTML page that will be
printed, so the user can preview the style changes dynamically (I am
not sure how doable is this)
but if there are no dives in the list, no data will be available to be printed.
falling back to some default / mockup contents or always using them is
the option i recommend.
this way, for no dives in the list, the user can still go in the print
dialog, modify and store his template while previewing a mockup.

III. Design solid ideas. we may have to adjust the naming of the classes slightly (e.g. just Printer instead of CustomPrinter), but we also have to consider the support for social networks, related class names and to plan the class inheritance. Grantlee templates This are the preexisting templates that can be used directly. yes, keeping the current templates is nice. Figure(3.1) Printing block diagram the graph looks good. if can you visualize what i mean by the above comment about QPrinterDialog, basically the CSS / HTML will be fed (e.g. with search-and-replace amends) with stored settings in the user configuration (from QSettings) and also with on-the-spot configuration such as margins, orientation etc. from the QPrinterDialog, then QPrinter will receive the rendered result as a paint device.

The proposed new dialog figure(3.4) nice, in general this is the idea about the new dialog. user suggestions are welcome about this one. Template options the 3 tabs cover what is required pretty much. how do you plan to generate the previews BTW e.g. QWebView rendering some sort of default contents on a QPixmap that is placed in the dialog? user suggestions are welcome about the layout and functionality listing of the dialog. General user can choose paper size, printing quality, margin size. all of these seem fine to be on the rendered side (e.g. Chrome has them), but if the user chooses something from the printer dialog (lower level - read closer to the OS and hardware) we may have to override some of them with or without notification. Style user can control the font, font size, and colors. random color generator can be included. nice. users will surely voice about more things in here. we should keep this tab's contents to a minimum at first, but best would be to consider a QScrollArea, just in case, as the CSS flexibility will open more feature requests. there are two options here. the contents of this tab: 1) should make sense for any possible template. 2) will update based on what is copy-pasted in the next tab option 1) is much easier as we don't have to deal with the dynamic creation of Qt UI. we may have to discuss this further. but i would say, consider 1) for now... Template this will add the ability to change the source code of the template, this will provide very advanced customization and the ability to change where and how does the data appear. an update button will be needed to re-visualize the theme in the preview. 1 dive per page 2 dives per page 4 dives per page Flow layout Column flow layout i'm sure Flow layout and Column flow layout will be good examples for what is possible with the new template stack. A. Milestones B.

I would be applying for two projects, both under subsurface. One is for implementing the VPM algorithm in c/c++ and the other is for enhancing CCR support. I have successfully built subsurface on Ubuntu and tried some tinkering around using Qt creator. I am trying to solve #839 (addition of another stop at 5m/15ft). I have been coding in C++ and embedded C for about six months and I still have a lot of coding to learn. I have been coding in embedded C as part of a group (we are making a student satellite!) so I have an experience similar to Open source coding, but this is my first foray into open source coding. I have already learnt a lot of things while preparing for the GSoC application and am really excited about it. I am here to learn coding from the subsurface community and, eventually, contribute to the FOSS community.

If you have any idea on how I can fix the linking problem, please let me know. As I said it before I have a OpenSuse 13.2-KDE-x86_64 platform. The linker version is GNU ld (GNU Binutils) 2.24.51.20140703. and the version of mingw64-make is GNU Make 4.0. For the moment I will skip the cross-building process and I will try to finish my proposal and to discover other ways to contribute. not good. this is a linker bug and without debug symbols and more information it's impossible to debug. it also could be running out of memory. are you running in a VM by any chance? if so try lifting the memory cap. c++ object code is heavy and filled with junk. trying another (e.g. older) binutils toolchain might also be an option. lubomir -- No, I don't run it in a VM and I believe the configuration of my machine is pretty good (8GB DDR3). I also checked the user limit for a process and it is set to unlimited. I suspect that it is caused by a library that the tool-chain is linked against but I don't know which one. When I will have some time, I will try to get the debugging sources of the tool to see if I can find something useful. If not, I will try to rollback to an older version as you suggested.

It lists the things you should do when considering sending a proposal for Subsurface. And those include 1) understand our contribution guidelines 2) build Subsurface from source 3) submit 2 patches 4) introduce yourself on the mailing list I have seen only a handful of students fulfill these requirements so far.

I.e. you can already tune your gradient factors to make it mimic any reasonable bubble based deco schedule within the appropriate uncertainty. Let me once more point out my pamphlet (in German) about this: http://euve10195.vserver.de/~robert/dekotheorie.pdf http://euve10195.vserver.de/~robert/dekotheorie.pdf One of the things that crack me up about the implementations of bubble algorithms that I have seen so far is that they all have these unexplained constants that are thrown in - and those constants have been carefully chosen to make the profiles generated by the bubble algorithms match the Buehlmann profiles...

Re: GSOC 2015
Robert, Rick, we are also very interested to have VPM running on a real diving computer; that's one reason, we build our oDiCo project based on a CORTEX M4 kernel, we are using a STM32F4, that has a build in FPU to speed up floating point operations. We think it is very important for divers to know about the deco modell they are diving with. In former times Bühlmann's model was well documented and dive computers, like the ALADIN, worked close related to the diving tables based an the Bühlmann model. When diving with modern deco models, like Suunto's RGBM, I am always in doubt about the thoughts of my diving computer, because these modern models are closed shop, no way to check the proper operation. We think it is time for the open source idea also in diving computers, for the planning of a dive as well as for the dive itself in real time. An good structured, well documented open source implementation of VPM-B as a C-Lib would have the chance to get a proven modern bubble deco algorithms, that could be used in desktop computers and also in diving computers. I could be evaluated by a lots of peoples ... Your comments? Tom Am 14.03.2015 um 14:27 schrieb Robert C.

[GSoC 2015] Introduction
Hi there, I believe that it is time to introduce myself and to let you know that I intend to apply for the idea Native Bluetooth support for Linux and/or Windows - GSoC 2015. My name is Claudiu Olteanu and I am a bachelor student at the University Politechnica of Bucharest. I have a strong background in C language and some bluetooth experience from GSoC 2013 edition where I implemented a bluetooth transport plugin for GNUnet organization. Until today I managed to build the sources on a Linux platform, to play a little with the interface and to watch the tutorial. Unfortunately I'm not a diver and I don't understand all the terms but I have faith that I will learn all of them soon. I also fixed an issue (probably the easiest one :) ) and I hope that I will continue my contribution. Since the idea should be implemented both on Linux and Windows I decided to build the project for the last platform too. As I expected this process is not as easy as the one for Linux but I am confident that I will succeed. I also want to know if: - some ideas have a higher priority than others to be accepted, or the difference will be made by the applications; - I should talk here details about the implementation or I should contact the mentor assigned for the bluetooth idea; - I can publish my proposal here when it will be in a good shape to receive some feedback.

Excellent! Certainly one of the projects that I was hoping we'd find a talented student for... (and before any of the other students start to worry... I'd say that for pretty much every single one of the projects... that's why they are on the list :-) ) My name is Claudiu Olteanu and I am a bachelor student at the University Politechnica of Bucharest. I have a strong background in C language and some bluetooth experience from GSoC 2013 edition where I implemented a bluetooth transport plugin for GNUnet organization. That does sound like you would be a good fit for this project! Until today I managed to build the sources on a Linux platform, to play a little with the interface and to watch the tutorial. Unfortunately I'm not a diver and I don't understand all the terms but I have faith that I will learn all of them soon. I also fixed an issue (probably the easiest one :) ) and I hope that I will continue my contribution. It's perfectly OK for the two patches to be really simple things. What I am looking for is to make sure people are able to send clean patches, can deal well with feedback (a couple other candidates who picked harder problems had to go through a few redo cycles), and overall seem to fit into the way we do things in Subsurface... Being a diver is really not necessary. Lubomir, one of our top contributors, is not a diver. Tomaz, our #1 contributor, wasn't a diver when he started. He's now certified and has done a couple of dives... but without meaning any disrespect to him or his skills as a diver... he still isn't exactly a DIVER :-) None of the four students from last year were divers, and two of them are still quite actively contributing... Since the idea should be implemented both on Linux and Windows I decided to build the project for the last platform too. As I expected this process is not as easy as the one for Linux but I am confident that I will succeed. Building natively on Windows is SO MUCH PAIN that I suggest that you don't do this. It's reasonably easy to cross build from Linux for Windows (which is how the official binaries are created). I have switched tool chains about half a year ago, so I'm not sure the scripts in packaging/windows are still 100% correct, but I can easily make sure that's the case. Which Linux distribution do you use? I also want to know if: - some ideas have a higher priority than others to be accepted, or the difference will be made by the applications; Nope. It will be entirely about the application. I think last year we had one that several of the principal developers here really really wanted to have - and we ended up not picking any of the candidates for that idea since we just didn't think their proposals were strong enough. On the flip side we had an idea that was more of an afterthought and that we picked because of a strong candidate (and he's still around, contributing). - I should talk here details about the implementation or I should contact the mentor assigned for the bluetooth idea; We don't have the mentors assigned, yet. - I can publish my proposal here when it will be in a good shape to receive some feedback.

Let me nit-pick a little :-)
a) the events are ordered by time, so the moment you have one where
time.seconds 0 you can stop
b) even easier, we have a helper function you could use:
get_next_event(ev, gaschange);
so you call this with current_dc-events
if you get an event back AND its time stamp is 0, remove that event
try again, again with current_dc-events as pointer
repeat until you don't find a gas change
c) I wouldn't call replot() in the middle; while it's unlikely that there
would be two gas changes at t=0, still one replot() would be sufficient,
right? So I'd have a little flag (bool eventRemoved) and then call
mark_divelist_changed() and replot() if eventRemoved is true.
Makes sense?
I know that this might feel frustrating. You keep sending patches and I
keep criticizing the code and not taking them. This really is intended to
help you and to make sure you understand the code and the code we have in
the end makes sense. Sure, I could just fix this myself (that would be a
lot less work for me) - but it's unlikely that you'd learn something if I
did that.

Adding integration with more online dive logs GSoC 2015
Hey subsurface, My name is Yousef Hamza, and I'm 3rd year CESS student, I already have contributions to subsurface the desktop app and the iOS app. I'm interested in adding integration to subsurface with established online dive logs, In the description diveboard.com was mentioned I googled a little bit more to find what else out there. I made this list of other online dive logs that also provide REST APIs, I don know they fit with subsurface or not as of now, Anyway here's the list: -diveseven.com (Their API still in beta) -dive.io So before starting to write the proposal I have a couple of questions: 1_ The mentor isn't announced yet, but Is there someone who are most likely will mentor that project? 2_ How important this project to subsurface? 3_ What will be a satisfying output for you? and Is it include some of the websites from the list I mentioned above? Thanks in advance. §Yousef ___ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface

I attached a pdf printout of the QWebview rendering the HTML template and a QPicture rendered on top. it seems to offset the profile QPicture a little vertically for each page (moves it little above of the designated area), which could be a rounding error. hopefully fixable by something like qRound() on our side. lubomir -- ___ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface

Re: Customizable Print Formats GSoC 2015
I've only really scanned this thread, so please excuse me if I'm raising something that's already been covered. It seems we're talking about rendering using HTML along with a few other things. Have we considered pagination? I know this is something that HTML isn't great at. You can, of course, print html, and it will paginate it, but is controlling how this happens easy? I understand there is support for pagination in CSS - is this enough for us to do reasonable looking 1 dive per page, 2 dives per page, etc? Or, are we considering rendering each dive as an individual HTML document, and then have the framework code assemble that into a pdf/print commands, etc? One of the reasons i raised this as a possible GSoC project was the poor experience when you have any more than a few lines of 'prose' in the notes for a dive - I tend to waffle a bit in some of my dive logs.

CSS supports 'page-break-inside' property which define whether a page break is allowed inside a specified element or not, also max/min height can be used for pagination, but taking into consideration that the overflow of long notes will either be trimmed or will expand the dive to more printing area and in this case we can't ensure to have N dives per page (this can be something like flow layout).

To get an idea what people’s paper divelogs look like in the wild, do a google image search for “dive log template”. Compared to what we have now, we need much better control over spacing (inclunding whitespace, there we currently waste far too much precious room on the paper), fields for which we don’t have information should in many cases not be displayed and the room be used for what we actually have etc. For me, for example, beyond the very basic information (date, depth, time, location, buddy), the notes are by far the most important textual element and should occupy sufficient room (in a decent font size). As far as i can understand http://qt-project.org/wiki/QtWebEngine , Qt's html renderer is based on chromium so i don't think its lacking any bells and whistles.

To get an idea what people’s paper divelogs look like in the wild, do a google image search for “dive log template”. Compared to what we have now, we need much better control over spacing (inclunding whitespace, there we currently waste far too much precious room on the paper), fields for which we don’t have information should in many cases not be displayed and the room be used for what we actually have etc. For me, for example, beyond the very basic information (date, depth, time, location, buddy), the notes are by far the most important textual element and should occupy sufficient room (in a decent font size).

This will need a lot more testing to check how this will actually work. the current printlayout.cpp supports NxM (even if the UI only allows certain ones). there is simple formula that is used for that. basically it takes the N and M parameters and based on the available space on the page and padding it estimates the size of single dive (profile + table). the problem with this approach is that if, say the dive notes are too long they may not fit in the singular estimated space for a dive. the alternative is to feed only N (e.g. columns) and produce a more fluid layout where a dive can span vertically even to multiple columns if it has longer notes. the next dive starts at the column where the previous one ended (think newspaper). lubomir -- ___ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface

have it complied on Windows so perhaps you can try setuping a simple

I built Grantlee on linux and I am going to look more into it these days. I
love the fact that Grantlee produces HTML files that can be printed easily
with neat quality without the need to reinvent the wheel.
I'm -1 for depending on tex because it's a huge package and a mess to
install it on windows
if we can get your idea to work then we can use it for printing, while
the TeX export is still viable as a separate feature.

Have you looked at our ideas page? We have quite a few ideas listed, but we aren’t really planning to do anything on IOS. The license of our main application is incompatible with the iTunes store… If you have an idea what you think we should do, you are of course always welcome to suggest your own ideas /D ___ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
Re: GSoC 2015
Don't you think the whole statistics feature would be a good candidate for a delimited project? Subsurface has the whol data structure so every statistic is a view of that data and can be developed as a single unit.

Re: GSoC 2015
So here are some ideas that I have seen... - more flexible print formatting Something template based that the user can modify - unit testing We have a start, but this needs a lot more work - asset management Ability to manage all the equipment that a diver has with them on a dive, including grouping, tracking weights, etc - more work on the Android full Subsurface Implement useful dialogs with QML or QtWidgets. NOT build a new UI, but tune the existing UI to be more Android/touch friendly - adding integration with more online logbooks There are several more out there that have an API What else? /D ___ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface

It is a really useful tool but it still needs lots of development. For starters it currently never gives the max depth of a dive. The basic dive list should contain the max depth and dive duration, the temperatures (currently shown) are less important. The presentation of the dive profile is totally inconsistent. Sometimes it gives the pressure of the cylinder, other times not, I think only when the cylinder pressure is measured my a transmitter. This is not very useful for the bulk of the recreational folk. I really think there is a useful place for this tool and it would really be to the advantage of all users if it could receive some concerted attention, not just piecemeal fixes.

After a re-read of http://trac.hohndel.org/wiki/Subsurface_GSOC_2014_Idea_List * Continuous Integration Framework I know that you cooked something for the daily builds. Do you think there is something left there worth looking at as a gsoc project? No - what I have works for what I need and makes my job easy. I don't see any value in having someone develop a competing system. * Native Windows/Linux/OS-X Bluetooth rfcomm The Windows and Linux parts are pretty straight forward. The OS-X bits are a mess, because rfcomm isn't a socket api there... Yes, that should be added. I have a promise to get a Mac BT implementation soon. Windows and Linux still have to be addressed. Jef did some POC patches for libdivecomputer quite a while back. Those might be good inspiration. * UI/UX polish? Especially the planner... Having random students work on the UI is unlikely to get us ahead unless we have specific wirefeames that they can implement... This was more a desperate hope for a student with awesome design and ux skills =) I'm probably just dreaming... //Anton -- Anton Lundin+46702-161604 ___ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface

Also the clock sync it terrible from a user perspective (no feedback what gets matched to what). The other big thing is of course a UI for git load/save.

Re: GSoC 2015
We have very good HTML export as a result of the last GSoC. Have you played with it? Are there features missing from it? If yes, I’m sure Gehad will be curious to hear what you’d like to see added… I only mentioned HTML as some form that could be printed as a log book. Yes, it is excellent, but very interactive, and not close to being usable for a printed log, nor does it have any customisable options over and above the few checkboxes for what to include. ie - while it is a great feature, and very well done, it doesn't come close to solving the 'printed logbook' problem. HOWEVER, what it does is provide the bare building blocks - eg profile rendered as an image/canvas. It does perhaps make it an easier option to do a XSLT transform on this data. Perhaps an option to do a more 'basic' export, as it looks as thought the current export is not a simple webpage but built up with javascript, and so it wouldn't be possible to transform it. ___ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
