Contact Link Backup

2009-11-25T18:12:25Z

Phwelo:

Unconfirmed, but I guess that contact links are store in

<pre><nowiki>/var/luna/data/dbdata/PalmAccountDatabase.db3</nowiki></pre>

or

<pre><nowiki>/var/luna/data/dbdata/PalmDatabase.db3</nowiki></pre>

It looks like the the table com_palm_pim_Person (in PalmDatabase.db3) has a field contactCount which is the number of contacts that are linked. (For entries just on the phone it is 1.) The linked contacts are then in the com_palm_pim_Contact table. (Connected by the field id in _Person and com_palm_pim_Person_id.)
(Thanks stephen-wood)

----
I attempted using these two files to backup and restore my contact links. After doing this contacts seemed to link but were not accessible. I then rebooted hoping that this would firm things up or just re-synch the contacts, but unfortunately it seems to have corrupted the contacts app completely. i can no longer see any accounts in the preferences and i'm also unable to add any new accounts. just a word of warning for anyone else looking into this - --[[User:Phwelo|phwelo]] 18:12, 25 November 2009 (UTC)

On Screen Keyboard

2009-08-01T19:18:43Z

Phwelo: /* On Screen Keyboard: A path forward */

=On Screen Keyboard: A path forward=

The Palm Pre already COMES with an on-screen keyboard. It works in portrait and landscape, in all apps, in all fields.

Press the "sym" key and a scrollable 5x5 keyboard pops up full of alternate characters.

This is controlled by /usr/palm/frameworks/mojo/submissions/191.15/javascripts/widget_charselector.js

with the layout controlled by 3 files in /usr/palm/frameworks/mojo/submissions/191.15/templates/charselector

the actual list of characters that appear on the screen is controlled by /usr/palm/frameworks/mojo/submissions/191.15/resources/en_us/alternatechars_table.json

At the simplest level then, creating an on-screen keyboard requires editing the alternate characters table json, to add the "regular" charcters to it, and then when you want a keyboard, press SYM and poof, a keyboard.

At the next level, widget_charselector.js needs to be modified to not close the keyboard after each keypress.

A more sophisticated version would require editing widget_charselector.js to make the widget wider to accomodate more characters at a time, or perhaps a qwerty layout.

A further refinement would require digging into the mojo framework deeper. It would be really "neat" if you were in a text field and the keyboard "popped up" if the slider was closed. This would be "harder."

Still, this is a path forward which is something we haven't had before.

Please edit this page with your thoughts, and proposals.

Patch webOS Random Wallpaper Switching

2009-07-31T15:34:23Z

Phwelo:

===Homebrew App for Random Wallpaper Switching===

There is now a homebrew application (no rooting required) that allows this same function without performing the patch below. It can be found at http://forums.precentral.net/homebrew-apps/195990-switcharoo-random-wallpaper-switching-v0-9-0-7-30-a.html

=== Goal===

On my desktop I have installed desktop drapes and my wallpaper switches every few hours to a random image in a wallpapers folder. I wanted to have the same functionality on my pre.

=== Requirements===

* [[Portal:Accessing_Linux | Access to Linux]] on your Pre.
* [[Next_steps | Installed backdoor with sudo]]
* The PATH variable should be set up in your .profile in your backdoor account, for example mine is set as follows:
<pre><nowiki>export PATH=$PATH:/bin:/sbin:/usr/bin:/usr/sbin/:/usr/local/bin:/opt/bin:/opt/sbin</nowiki></pre>

=== Procedure===

Note: I prefer doing everything with sudo and not logging in as root via the backdoor. I would recommend getting into the same habit.

==== Transfering Wallpapers====

* Connect your Pre to your computer as a USB drive.
* Create a folder named 'wallpapers' on the Pre (if its not already there).
* Put all your wallpapers there.
* Disconnect the Pre from your PC. You might want to make sure to disconnect it safely so everything writes to storage okay.

Make sure to remove any wallpapers which you don't want to show up, though, since the switcher will pick a random one.

==== Enable Write Access====

<pre><nowiki>sudo mount -o remount,rw /</nowiki></pre>

==== Enabling Cron====

Go [[Crond | here ]] to enable crond.

==== The Wallpaper Switcher Script====

First lets make a place for the script:

<pre><nowiki>sudo mkdir /opt/share/wallswitcher</nowiki></pre>

Edit wallswitcher.sh inside /opt/share/wallswitcher directory and place the following code there:

<pre><nowiki>
#!/bin/sh

main()
{
DIR='/media/internal/wallpapers/'
IFS="
"
NUM_FILES=0
for cur in `ls -1 $DIR`; do
if [ -f "$DIR$cur" ]
then
NUM_FILES=$((NUM_FILES+1))
eval "FILE_$NUM_FILES=$cur"
fi
done

RANDOM_NUMBER=`awk "BEGIN{srand();print int($NUM_FILES * rand()) + 1;}"`
eval "RANDOM_FILE=\$FILE_$((RANDOM_NUMBER))"
IMPORT_STRING="{ \"target\": \"$DIR$RANDOM_FILE\" }"
SET_STRING="{ \"wallpaper\": { \"wallpaperName\": \"$RANDOM_FILE\", \"wallpaperFile\": \"$DIR$RANDOM_FILE\" } }"

echo "Found $NUM_FILES in $DIR"
echo "Using random file: $RANDOM_FILE"
echo "JSON Import String: $IMPORT_STRING"
echo "JSON Set String: $SET_STRING"

eval "luna-send -n 1 palm://com.palm.systemservice/wallpaper/importWallpaper '$IMPORT_STRING'"

eval "luna-send -n 1 palm://com.palm.systemservice/setPreferences '$SET_STRING'"
}

main
</nowiki></pre>

Save the file and make sure it has execute permissions. The following command will insure that:

<pre><nowiki>sudo chmod 755 /opt/share/wallswitcher/wallswitcher.sh</nowiki></pre>

Some notes on the script:
* I am a Java/Groovy developer mostly and am not as good at shell scripting as I would like. Any improvements on the script itself are welcome
* The main piece of code that performs the switch are the two luna-send commands. T he first command is required if a wallpaper has never been used before and will generate some thumbnails and copy the main image into /media/internal/.wallpapers. The second luna-send command actually performs the switch.
* This method currently only supports wallpapers sized to exactly 320 x 480 px. The import luna-send call can take more parameters in its JSON string, such as scaling and x/y offsets from center. I have not used these yet since all my wallpapers are correctly sized.
* Again, being a not-so-good shell developer, the way I obtain random numbers and use them is a bit wrong. Awk is used to get a random number. Instead of arrays (as in bash), dynamic variable naming is used.
* The DIR variable controls where the script looks for wallpapers—you can change it to where your pictures are instead. Currently the scan is not recursive.

==== Testing the Script====

If you have more then one wallpaper in /media/internal/wallpapers, you can test the switcher with the following command:

<pre><nowiki>sudo /opt/share/wallswitcher/wallswitcher.sh</nowiki></pre>

The response should look something like this:

<pre><nowiki>
Found 24 in /media/internal/wallpapers/
Using random file: wall_409.jpg
JSON Import String: { "target": "/media/internal/wallpapers/wall_409.jpg" }
JSON Set String: { "wallpaper": { "wallpaperName": "wall_409.jpg", "wallpaperFile": "/media/internal/wallpapers/wall_409.jpg" } }
** Message: serviceResponse Handling: 2, { "returnValue": true, "wallpaper": { "wallpaperName": "wall_409.jpg", "wallpaperFile": "\/media\/internal\/.wallpapers\/wall_409.jpg", "wallpaperThumbFile": "\/media\/internal\/.wallpapers\/thumbs\/wall_409.jpg" } }
** Message: serviceResponse Handling: 2, { "returnValue": true }
</nowiki></pre>

If the two service calls are not returning correctly, something is wrong. Contact me (fxdemolisher[at]gmail[dawt]com) if you are stuck debugging it.

==== Schedule the Script====

This step is pretty easy. Since you have an empty root crontab set up all that needs to be done is a scheduling command. Edit /etc/cron/crontabs/root and place the following scheduling test line:
<pre><nowiki>*/1 * * * * /opt/share/wallswitcher/wallswitcher.sh > /opt/share/wallswitcher/wallswitcher.log 2>&1</nowiki></pre>

This will execute the switcher every minute and log to the /opt/share/wallswitcher/wallswitcher.log log. After you have it switching correctly every minute you can edit the cron definition to run as often as you like. Mine is set to run at the top of the hour using this line:

<pre><nowiki>0 * * * * /opt/share/wallswitcher/wallswitcher.sh > /opt/share/wallswitcher/wallswitcher.log 2>&1</nowiki></pre>

NOTE: Do not use crontab -e as this does not really write to /etc/cron/crontabs/root and will be overriden when the device restarts.

==== Restore Read-Only Filesystem====

<pre><nowiki>sudo mount -o remount,ro /</nowiki></pre>
