Re: [Announce] modRana: a flexible GPS navigation system

Wonderful app! Particularly the tracklogging which I like for sailing (one can determine when to tack).

<problem> I lost the crosshair/fix/pointer as well as the tracks and start/end pointers. Latest build no improvement.

Re: [Announce] modRana: a flexible GPS navigation system

Martin: In the bug on causing the SGX driver to lock up, the Nokia rep noted the problem may be from sending too much to the drawing system. (Bogus, I know, but...) One thing of note was placing an entry in /etc/powervr.d/ for the program to "increase it's GL command buffer". I'm not sure how this is done though. Thought maybe you'd have and idea? :)

Re: [Announce] modRana: a flexible GPS navigation system

v 0.20-3 fails in postinst while chmodding /opt/modrana/cache/images/

It fails since there's dirnames with spaces in this dir, if you've downloaded some files, and the busybox `chmod -R' doesn't cope with these it seems...

Modrana won't start at all now. I have only tried out setting buttons and have not tried to reinstall or other installs. I'm quite ignorant of the technique so I have no real clue.

Start in Xterminal shows the following

Code:

~ $ modrana

 == modRana Starting == 

 device string (first parameter): n900 

importing modules:

 * menu: Handle menus (30.00 ms)

 * example: A sample pyroute module (10.00 ms)

 * clickHandler: handle mouse clicks (10.00 ms)

 * waypoints: Lookup nearest town or village (80.00 ms)

 * messages: Handles messages (120.00 ms)

 * onlineServices: Module for communication with various online services. (170.00 ms)

 * mapView: Controls the view being displayed on the map (0.00 ms)

 * display: A platform independent display device control module (0.00 ms)

 * icons: Draw icons (10.00 ms)

 * log: A modRana logging module (0.00 ms)

Traceback (most recent call last):

  File "modrana.py", line 476, in <module>

    program = GuiBase(device)

  File "modrana.py", line 411, in __init__

    self.mapWidget = MapWidget()

  File "modrana.py", line 85, in __init__

    self.loadModules('modules') # name of the folder with modules

  File "modrana.py", line 106, in loadModules

    self.m[name] = a.getModule(self.m,self.d)

  File "/opt/modrana/modules/mod_options.py", line 25, in getModule

    return(options(m,d))

  File "/opt/modrana/modules/mod_options.py", line 33, in __init__

    self.load()

  File "/opt/modrana/modules/mod_options.py", line 369, in load

    newData = marshal.load(f)

EOFError: EOF read where object expected

~ $

Would it help to uninstall or sth? Or can some1 provide info on a detail?

I'm not experiencing other big failures other than some widgets falling out. I have toggled 3G/GSM while running Modrana by the way

<edit> I have tried reinstall (OTA). Xterminal session of modRana still shows the above. I can safely say that I left mod_options.py untouched, so far as I made no textual alterations whatsoever.

I miss this app with its k i c k a s s tiles, could anyone help restoring this modRana 0.20-3?

But then I heard that from some people the whole time, and mine was never good at keeping a GSM signal, yet alone handling calls or text. :P

I think I have seen a lecture about QtMoko by one of the developers (maybe it was even the main developer ? I'm not really sure) on the OpenMobility conference, that took place april. It looked very usable even then :) BTW, there is a (bit old) howto for running modRana on QtMoko :)

BTW, concerning flashing - I have been using dfu-util in Linux to flash about everything in Neo, including rootfs (SHR), kernel and even the non-hardwired bootloader quite recently - without issues once I set the correct path and usb id.

Well, the street names actually come enclosed in <b></b> tags. The enclosed text could be taken as a whitespace separated string and only those St. that have no whitespace behind them would be substituted :)
IMO, this looks like a textbook use-case for a regexp ->
I think I'll just add support for adding custom regexps to the filter file :D
Something like:

Code:

regexp;your_regexp_code

You need to be careful with these, they do not work as expected, which relates to the previous post also. Basically modrana just does a plain substitution, not whole words. I.e. if you have

Code:

St;Street

this is wrong as then for instance "Park Street" will be read as "Park Street reet"
so maybe it should be:

Code:

St ;Street

Yep, its just really simple exact-match (including whitespace) substitution right now. It also applies ALL the rules, one after another, going from the first line to the last.

So you should use either

Code:

St. ;Street

Code:

St.;Street

, depending on how the streetnames are shortened and also watch out for substituting to something that might match match a rule further down the list :)

OK, upgrade-time merging seems like the best way, it might be less confusing than having two separate default (always overwritten by upgrade)/user(never overwritten by upgrade) filter files, etc. I just hope all the needed utilities are there in our (quite) limited busybox shell :) Also, there might be problems with order of the rules in the merged file.

Also, thanks for all the new substitution rules! :)

Just a question to the gkuenning ones:

Code:

Ave;Avenue

Cir;Circle

Hts;Heights

Hwy;Highway

Ln;Lane

Pde;Parade

Pkwy;Parkway

Pl;Place

Plz;Plaza

Rd;Road

Sq;Square

Tce;Terrace

Trk;Track

Wy;Way

Is there really no period behind those abbreviations ? It hight potentially mangle some unabbreviated street names (5th Avenue -> 5th Avenuenue), like jj0 mentioned earlier.

BTW, the new version is MUCH slower in loading the individual tiles for display, must be doing some caching or what-have-you, but now there is a noticeable lag, and the "Loading..." text showed for about a second or so, with every tile upon first display, then when it's redisplayed, i.e. zoomed out and back in, it's instantaneous, but it used to be instantaneous before...

I have changed how tile drawing/loading works. The drawing function previously handled everything - not only drawing but also caching the tiles (loading from file/sqlite or starting download threads) in case they were not in the memory cache.
This froze the whole GUI once there were enogh new tiles on the screens, because the drawing function waited for all the new tiles to load. There was also no limit on the number of concurrent download threads, which is another matter. I think you can imagine what happened if you entered an area with poor network coverage at hight speed without any thread-count limit :)

I have changed how tile drawing works like this:

the drawing function now only draws tiles that are cached in the memory cache, if there is a cache miss, it sends a loading request for the missing tile and loads a "Loading..." placeholder tile in the cache - like this, only one loading request is sent per missing tile
a separate consumer thread handles the loading request queue - it either loads the tile from local storage (file/sqlite) or sends a download request to the download request pool
a second consumer thread is responsible for starting the download threads, it also makes sure that the number of concurrent download threads never exceeds a given limit (20 by default), unprocessed download requests time-out after 30 second

The slower apparent loading of tiles might be caused by the default once-per-second screen refresh.

If you are not dragging the map, modRana updates the screen only once per second, as this is the shortest interval I can get a new fix in. Not much sense to update more often IMO. The first redraw draws the "Loading..." tiles and sends loading requests. And only the next redraw that happens a second later shows the actual tiles that were loaded to the cache in the meantime.

I think sending a screen redraw request once a tile is finished loading might improve/fix this.

Anyhow, I backed up the .maps folder, then created a new empty one, and am now downloading maps for a 80 km area around a point.

It's been going on without errors for some time now, now at 39 thousand out of 360 thou...

Have you tried how the batch download to sqlite fares in 0.20-3 ? I have made the database access sequential in this version as I suspect that concurrent access to the database might be causing for all those "database locked" errors.

In XXX meters turn right on XXX Street reet slash emphasis

I.e. the "Street reet" part was because of the St; substitution, but pronouncing the "slash emphasis" seems like it's reading a </emphasis> tag...

It doesn't do it all the time though, so not sure if only when it's ending in "Street"...

The emphasis tags come from SSML are used so that espeak puts emphasis on important words, like street names or the turn commands. IMO it is reading the tag because it is somehow mangled - either the is a < missing or the <emphasis> opening tag is not where it should be. Does it happen for all turns or just from time to time ?

BTW, modRana is not actually drawing that much, but it does redraw the whole screen each time. ModRana redraws frequently only when the map is being dragged, otherwise the screen is redrawn just once per second, (as mentioned earlier). The weird thing is that most of the freezes that have been reported for modRana so far were IIRC not while dragging the map but while just looking at it or even when the screen was blanked.

Maybe it doesn't like when applications redraw while the screen is blanked ? I think I have noticed something in this sense in one of the new comments to the freezing bug.

This might be caused the by corrupted settings file. Try to delete/move somewhere else this file:
/opt/modrana/data/options.bin
ModRana will create a new one with default settings if it cant find the old one. This might even solve your other problem with missing position indicator.

Also, failed loading of the options file should really fail more gracefully, with a "loading settings failed" notifications and not with a crash... I'll do something about it :)

No, it doesn't recognize your voice commands as you speak them.

Yes, it does pronounce the route turn-by-turn, with help of espeak, if you have Internet to get routing from Google.

Yeah, in the States these are usually spelled without the period... So regexp support is needed, since you'll have stuff like "Penn Ave" but you can't sub "Ave" (without the space) for "Avenue"...

I might add that it works better than first install (I think it was 2 versions before v 0.20-3). Namely, I believe after first install two blue squares where always present on navigation screen (mentioning: starting a track to calculate time to resp. start and destination). They're not there now anymore (hadn't figured those out btw; they remained always the same*).

*edit: except in your exemplary tracks, somewhere way out east :D

I was having the same issue. 0.20-3 fixed it for me. :)

I also found part of the issue with my longer trip? Apparently something in the install is nuking the sqlite db files? When I updated to the new version the db file went away. So I'm backing those up now before updates in the future. :)

I'm testing an option or two right now. If I go lock-up free for a while I'll post my settings here. It's a bandaid to what's clearly a kernel bug, but it's better than nothing. (Which is what Nokia is good at delivering so far.)

Re: [Announce] modRana: a flexible GPS navigation system

Just noticed that TTS does not quite follow the device volume setting, if I lower volume using the hardware keys, TTS volume lowers, but it can get louder by itself again, or new TTS messages start at full volume.

This is with the latest version in -devel

Re: [Announce] modRana: a flexible GPS navigation system

<noticed>
-Changing from Car Mode to another mode and then back to Car Mode--> two blue rectangles are added to the navigation UI. They mention adding a track to show time to either start or destination.
I'm unaware what function these rectangles have to have. Do they contain a future feature? Like more info on route? I noticed in the exemplary logs they turned up with a function.
(forementioned removal/renaming of file named /opt/modrana/data/options.bin and consequent reviving of the same (after re-run) has modRana restart a UI without the rectangles)

<wildely proposed feature>
Another mode in which you could plot more than two (simple) track points would be very cool. If added by absolute directions (straight path) for each part of the route would make a Ship Mode. Visualization: dots with the wind direction and distance as indicator of where to go. Sky rocketing would it be if a straight line was drawn from present position to next track point :p but I guess this all would be a bieg job to realize.

<general question>
The GPX files. (What prevends them from being opened in Google Earth?) Is it possible to mutate those on PC (other program)?

Re: [Announce] modRana: a flexible GPS navigation system

So that I don't forget, I propose to move the cursor point when automatic display orientation is on...

Currently, your vehicle is exactly in the middle of the screen, which doesn't make sense, you don't have to see half screen of what you've already passed. So when auto-rotation is on, meaning you're driving, your position should be on the bottom of the screen, with maybe MAX 10 percent of what's behind you visible, the rest should be ahead of you, so you can consider what's coming up...

MartinK,
I have to turn debugging on, but I've had at least 2 occasions now when modRana has "closed" and turned off GPS, but remained "running" in the background. (eg, it's still there in top, like 2 hours later.) Not sure why, but... one more thing to add to the list? :P

Well, even though I currently don't see this as a high priority, it would quite easy to do. All graphical icons in modRana are just PNG files (you can find them in /opt/modrana/icons/bitmap) and other GUI elements are drawn with cairo at runtime. Skinning support would just mean a per-skin bitmap folder + color definitions for cairo drawing.

ModRana stores all map data in .MyDocs/.maps and shares the tile images with Mappero and Maep. If you enable sqlite storage in modRana, it currently does not share the database with anybody - I have designed the database to be easily shared with other programs but no other software has implemented it yet.
Don't know about the .map_tile_cache, but I have it too. Maybe it is used by Geeps, Ovi maps, AGTL, Buscatcher or some other software ?

If there's regexp then this should do it:

St\.;Street

Well, I have used a dirty hack fof Ave->Avenue and other ambiguous cases, for now :)
As there is currently always a closing a tag on the end of the street description just after the abbreviation, I have added a substitution rule like this:

Code:

Ave<;Avenue<

It just substitutes the abbreviation including the < with a full version, also with < :D

Concerning regexp support, after studing the documentation in more detail, it turns out that modRana already supports regexps :)

the re.sub function I have used used actually takes as pattern as input and substitutes all matches with a string given as its second parameter.

Just write a regexp with correct syntax on a line to the rules file, separated by ; from the string that should replace what your regexp matches. :)

The numbre of threads currently setable from options->network relates to threads for automatic tile download, that are used for automatically downloading visible tiles that are not yet locally stored.
The number of batch download threads is currently hard-coded, but it should be also user-configurable soon.

BTW, provided MyDocs is still writable after you get this error, it might be possible to reconnect to the database and recover from this error.

Thanks for reporting this! :)

I remember getting something like this in a quite while ago in scratchbox - I thought it might be related to the incomplete liblocation implementation present in scratchbox.

Looks like there might be another cause if this also happens on the device itself.

Yes, these rectangles are basic information widgets that report useful information about a tracklog. There are currently quite awkward to configure, but should become quite usable when I finally add the long promised interactive widget configuration.

Another mode in which you could plot more than two (simple) track points would be very cool. If added by absolute directions (straight path) for each part of the route would make a Ship Mode. Visualization: dots with the wind direction and distance as indicator of where to go. Sky rocketing would it be if a straight line was drawn from present position to next track point :p but I guess this all would be a bieg job to realize.

Custom road drawing and free navigation are both already planed :)

Does Google Earth support GPX (it works mostly with KML, IMO)? I tried to upload a modRana GPX tracklog to OpenStreatMap a while ago and it worked.

BTW, this might be quite a nasty bug as it would mean that the used memory would not get released + there might even be some useless CPU activity. Even worse if such processes accumulate.

Well, even though I currently don't see this as a high priority, it would quite easy to do.

Skinning support would just mean a per-skin bitmap folder + color definitions for cairo drawing.

Nice! I am starting on a new ModRana theme right now! Maybe eventually we will have themes which integrate with the system themes? (Obviously that will require a lot of work on the theme artists' parts ;) .)

BTW I too have been getting the "street slash emphasis" problem. I noticed also that voice alerts seem to come while I'm in the intersection - could these possibly be moved back about fifty yards or so? Also, would it be possible to round the distance? "In four hundred and ninety-five point eight yards" is no more helpful than "In five hundred yards" and takes a good while longer for eSpeak to say.

Re: [Announce] modRana: a flexible GPS navigation system

MartinK, I have two usability questions/requests:

1. I think it would be nice to only unlock the auto-centering when the user actually swipes, as rerouting or going into the menu always unlocks the auto-center. So ignore normal taps :)

2. For me the route info box should be only shown when I tap the screen, so that it is only shown when also the menu and maximize buttons are shown. And the routing box could be smaller too :)

I have recently started using ModRana as my main routing device, and I am generally happy with it! Keep up the good work man!

There are some (free) sites that offer to convert GPX to KML/KMZ, and even view them in a Google Maps page online. Easy to find with Google ;)

I spent many hours searching how to hear messages when mediaplayer is playing (it mutes all other apps).
solution was to write:
- - - - - -
[stream]
exe = espeak
group = ringtone
- - - - - -
into /etc/pulse/xpolicy.conf. btw espeakcaller does same!

now i can listen something over FM-transmitter and also hear navigation messages.

Thanks! What does that mean for the volume - would that make it use/follow the ringtone volume setting?

I could have told you that a while ago... sorry. :) Since the first time I was told to turn on to Some Street slash emphasis, I knew what it was doing. I work with regular expressions a lot, and any time a substitution eats a random character, it's usually because of a stray period. :)

Re: [Announce] modRana: a flexible GPS navigation system

I have created the first Modrana theme!! It is based mainly on iPhone icons. Download from http://www.mediafire.com/file/8p51x4.../bitmap.tar.gz to the n900. From xterm, run

Code:

root

cd <directory/you/downloaded/to>

gzip -d bitmap.tar.gz

tar -xvf bitmap.tar

mv /opt/modrana/icons/bitmap /opt/modrana/icons/bitmap~

mv bitmap /opt/modrana/icons

and restart Modrana if it is running. If someone knows a better way to extract this please tell me!

BTW martinK is some of the UI hardcoded in Cairo? My theme isn't changing the plain text boxes.
Also would it be possible in the future to use a user directory (such as /home/user/modrana) for storage of customizable elements so they are not overwritten on every update?

As can be seen in the third one, I am unable to modify the plain text boxes.

Google Earth can open GPX files. Just go to File > Open and select "Gps (*.gpx *.loc *.mps *.gdb *.tcx *.nmea *.log *.wpt *.plt *.pcx)" from the "Files of type:" dropdown.

I use Linux too (Mint specifically). If Google Earth is giving you a "43: ./googleearth-bin: not found" error, try running

Code:

sudo apt-get install lsb-core

and see if that helps. Dunno why Google doesn't make this a dependency.

Quote from a Google Maps help thread:

Quote:

I managed to import a GPX file directly to my maps, I think it is quite a recent change. I just used the "Import" menu in My Maps and supplied a GPX file istead of a KML file. It just worked!

I have not had success with this; Google Maps gives me a "Couldn't finish" error. I don't know what exactly is up with this.

Try to tweak the "Point reached distance" in options->navigation, this is what currently triggers the last routing message and switches to the next point. BTW, I'm currently working on improving the navigation functionality, including among others custom voice message triggers. :)

Good point about unnecessary long voice messages, I'll ad some rounding.

Well, it actually works like this when controlled by mouse :) IMO, this is because the touchscreen registers even a click as a slight drag which makes the centering disengage. I'll try to set some "drag-threshold" to fix this.

I'm going to add a minimize button (+ next/last turn buttons) on to of the routing info box. I guess I can also add a "hide with main buttons" option for the routing box. :)

Yep, some gui elements (centering button, position indicator, point descriptors, the blue box widgets, all buttons that have only text on them,etc.) are drawn with cairo at runtime. But I can add something like a color-settings file so that you can at least set the colors & opacity to go with the theme.
It might be also possible to render an image under/instead of those elements, preferably an SVG due to scaling but bitmap should also work, even if it might not be always sharp.

Or maybe even something like ~/MyDocs/modrana/themes or ~/MyDocs/modrana/themes so that it is visible and accessible from the file manager and in mass-storage mode ?

All buttons already use the same font/style, although the size-scaling is often a bit quirky. But good point about centering the labels, I'll look into it.

Good idea. I generally use FileBox so I forget that most directories aren't easily accessible.

Re: [Announce] modRana: a flexible GPS navigation system

Ok, i am new to this...can you use the map without internet or do you have to have internet to use the map? So if you're out in the car and don't have internet access...basically you can't use it?? Can you download and save map ?

edit: Ok, i just notice this thing can't do offline routing! Is it possible to add this feature?

Maps should be downloaded to N900 and it can be done at home beforehand (home Internet is usually faster and cheaper than mobile); don't download the whole map of the world, it's impossible (takes too much memory), just take the detailed region which you are going to visit, like a part of a city.

Maps should be downloaded to /home/user/MyDocs/.maps/ if "file storage" in Modrana is set to "files", not "sqlite". To prevent Modrana from downloading tiles over WiFi on the fly, set "Network"->"Only for important data".

For example, there are several programs to download OpenStreetMaps:
http://wiki.openstreetmap.org/wiki/C...le_downloading

Google and Yahoo Maps can be downloaded, too.
http://wiki.openstreetmap.org/wiki/GMapCatcher
http://code.google.com/p/gmapcatcher/

Offline routing isn't easy to add. It requires using and analysing vector data, understanding which paths are only for human/automobile/bicycle, one-way only roads, etc. But it may be added later, there is a ticket for it, I heard.
