Patch Camera Shutter Sound On-Off Button

2009-09-30T15:51:14Z

VictorKruger: added notiation at the top stating that this patch works with version 1.2

{{template:patch}}

Edit: This appears to work with version 1.2, When i applied this patch there was some fuzzing that occurred but when i loaded up my camera app everything worked.

Needed to try something to start playing with the Pre, so I decided to add a button to selectively turn on and off the shutter sound in the camera app.
All of the normal precautions and methods for modifying the existing apps apply here. I've tested this and it works fine on my phone, but use at your own risk.
NOTE: I'm not a great graphic artist, so the buttons are kinda crappy. If someone feels like creating some new ones, please do and post them here. Also, I'm not entirely fond of the button location, but it seemed to fit pretty well...feel free to change the location of the button in your own version.

Here is the .png of the new icons used:

Application:Terminal

2009-09-15T15:58:09Z

VictorKruger: added notiation of change in address to put in conf file

{{application
|name=Terminal
|type=webOS
|version=Version: Alpha 0.2.2 <br />(26 Aug 2009)
|tag=Utilities
|screenshot=Application_Terminal.jpg
|description=

== Summary ==

Terminal is a mojo applicaton for the Pre which runs a full VT-100 or Linux terminal in a mojo scene. Terminal relies on a custom written plugin developed from community research which allows the mojo app to talk to the back end. It can be used for local operation to run your Pre, or can reach out from the Pre to other computers.

== Status ==

This is alpha software. Consider yourself lucky if it works at all. Many people have put many hours of hard work in to get just this far - respect that effort when making comments and suggestions.

==Installation==
If you have installed [[Application:Preware|Preware]], WebOS Internal's over the air installer, you can simply choose and install the Terminal Plugin and then choose and install Terminal from the available applications.

If you have installed WebOS Quick Install to your PC, you can select and install the Terminal Plugin Terminal by pressing the third button, choosing the appropriate WebOS Internals Feed from the pull down, choose Terminal, download and install.

Install the plugin FIRST before installing the terminal application. Detailed command line installation instrutions can be found below.

== License ==

Please be aware that org.webosinternals.terminal and org.webosinternals.termplugin are licensed under the GPLv2.

They cannot be used by a closed source application. If you want to use them in a non-GPLv2 but otherwise open source application, please contact the authors.

== Operating notes ==

* (Sym is Control and Control I is the standard tab code)

Rotating the pre will take the terminal to landscape mode. The keyboard will not rotate with you. Attempting to physically force the keyboard to rotate to the proper orientation for landscape mode is known to bork a Pre. :)

Support for both "linux" and "vt100" term types should now be supported, so an export TERM line should no longer be needed. If you find your screen filling with gibberish that looks like ANSI codes, however, make sure you're using 0.1.4 or later version, and report here or in the IRC channel what you were running in the terminal that caused the issue.

If you do see odd behavior, you can force the more compatible vt100 terminal type by typing:

export TERM=vt100

(followed by enter) Note that the case of that command is important.

=== Recent enhancements ===

* Prompt for login to enhance security / protect against rogue applications embedding termplugin (more convenient and equally secure method being developed for future release)

* Color!

* Arrow keys, hold a finger on the gesture area so that the white LED lights up, and use the numbers area as if it were a direction pad (ie 2, 4, 6, 8, correspond to up, left, right, down, respectively)

* Several performance enhancements

* Screen scrolls automagically (no more flicking to keep up)

* Comma / underscore key bugs fixed

* Preferences are now saved

=== Known bugs ===

* The command 'reset' does not work; running it actually messed up the state of the terminal (ex. backspace no longer works).
* Some ansiFlags are not being used (ex. blink, italics etc. don't have any visual effect)
* The keybindings need to be redefinable.

Remember, this is early alpha software. You're lucky it works at all.

Reported issues:

* Doesn't display a return in nano properly unless the screen is rotated
* No action after running exit in session should restart and ask for a new login

Some limitations: Many keys are not implemented. We're working on it, maybe even as you read this. :)

Y and U: Y and U in the emulator return the same raw keycode due to a bug in the emulator. However we're obtaining the key values a better way now so terminal should no longer be susceptible to this flaw.

== Repository ==

Terminal is housed in the Applications section of the Webos-internals repository at Gitorious. http://gitorious.org/webos-internals.

Source code for the Mojo app can be browsed at http://gitorious.org/webos-internals/applications/trees/master/terminal

Source code for the plugin can be browsed at http://gitorious.org/webos-internals/applications/trees/master/termplugin

For commit permission to the project, contact destinal on #webos-internals or email [[mailto:predestinal@gmail.com predestinal@gmail.com]]

==Command Line Installation ==

'''This procedure is only for those very comfortable with the Linux command line. Everyone else should use the installation instructions above.''' Do not stray from or vary these instructions. If you don't do it all, in precisely the right order, with zero mistakes, it's not going to work. Copy & Paste will be your friend.

'''You need to be logged in as root with a writeable filesystem.''' Instructions for both those things can be found elsewhere on this wiki.

==== The first time you install terminal you must do all these steps: ====
<source lang="text">
mkdir -p /var/etc/ipkg/
ln -s /etc/ipkg/arch.conf /var/etc/ipkg/
echo "src/gz all http://ipkg.preware.org/feeds/preware/all" > /var/etc/ipkg/preware.conf
</source>

* If you are on the Pre, type:

<source lang="text">
echo "src/gz armv7 http://ipkg.preware.org/feeds/preware/armv7" >> /var/etc/ipkg/preware.conf
</source>

09/15/2009 The address has changed to http://ipkg.preware.org/feeds/webos-internals/arm7

* If you are on the Emulator, type:

<source lang="text">
echo "src/gz i686 http://ipkg.preware.org/feeds/preware/i686" >> /var/etc/ipkg/preware.conf
</source>

09/15/2009 The address has changed to http://ipkg.preware.org/feeds/webos-internals/i686

Then type:

<source lang="text">
/usr/bin/ipkg -o /var update
/usr/bin/ipkg -o /var install org.webosinternals.terminal
sh /var/usr/lib/ipkg/info/org.webosinternals.termplugin.postinst
</source>

Then refresh the GUI to show your new app:

<source lang="text">
luna-send -n 1 palm://com.palm.applicationManager/rescan {}
</source>

If you performed an upgrade and aren't seeing the changes, restart the GUI service:

<source lang="text">
initctl stop LunaSysMgr && initctl start LunaSysMgr
</source>

If the above two fail to show the results you're expecting, reboot the device.

=== Updating ===

==== After your first install, only the following is required to upgrade to a new version. ====

'''You need to be logged in as root with a writeable filesystem.''' Instructions for both those things can be found elsewhere on this wiki.

From a shell:

<source lang="text">
/usr/bin/ipkg -o /var update
/usr/bin/ipkg -o /var upgrade
reboot
</source>

=== Other PreWare Applications ===

'''You need to be logged in as root with a writeable filesystem.''' Instructions for both those things can be found elsewhere on this wiki.

Note that you can use the same commands to install other applications from PreWare:

<source lang="text">
/usr/bin/ipkg -o /var update
/usr/bin/ipkg -o /var list
/usr/bin/ipkg -o /var install <package> # choose a package from the list
/usr/bin/ipkg -o /var remove <package>
</source>

=== Removal ===

'''You need to be logged in as root with a writeable filesystem.''' Instructions for both those things can be found elsewhere on this wiki.

<source lang="text">
/usr/bin/ipkg -o /var remove org.webosinternals.terminal
sh /var/usr/lib/ipkg/info/org.webosinternals.termplugin.prerm
/usr/bin/ipkg -o /var remove org.webosinternals.termplugin
</source>

Then refresh the GUI to remove the icon:

<source lang="text">
luna-send -n 1 palm://com.palm.applicationManager/rescan {}
</source>

If you aren't seeing the icon removed, restart the GUI service:

<source lang="text">
initctl stop LunaSysMgr && initctl start LunaSysMgr
</source>

If the above two fail to show the results you're expecting, reboot the device.
