Version vom 28. Oktober 2011, 11:07 Uhr

Idee

Latest test image that has been uploaded by the testers of this script.

Upload ins Mediawiki via möglichst einfach gehaltenem Bash-Skript. Konstruiert, um via N900 direkt aus der Kamera-App Bilder hochzuladen - es kann aber auf jedem x-beliebigen System verwendet werden. Speziell fuer das N900 gibts die #N900 Extensions.

Anforderungen

Bash, Wget Sed, Grep mktemp

Hack-Faktor

Baut ein MIME multipart/form-data für wget, das das eigentlich nicht kann... Dürfte auch der Schwachpunkt der ganzen Angelegenheit sein...

N900 Extensions

Script

This is a script with the n900 extensions. It adds:

  • A bit more error handling (really, just a bit)
  • Support for N900 messaging system
  • Wrapping the share script into an osso-xterm
  • Prefixing of files. (This is necessary as the photo app will name the photos by date and and incremental index that is reset once per day. Thus two people using the camera app with sharing on the same day are very likely going to overwrite their pictures.)

Setup

Download the script and put it into a file, e.g. /bin/2wiki.sh. chmod a+rx it and configure your wiki account (first few lines of the script). Install Command Line Sharing form your application manager. Go to Settings -> Sharing Accounts, add a new command line sharing account with the following settings: 

/bin/2wiki.sh wrap-n900-xterm "%s" "%s"

This will open an x terminal which contain a rudimentary log. If you want silent upload using only the n900 messaging system, add the following cli sharing account: 

/bin/2wiki.sh allow-n900-messages "%s" "%s"

Usage

Make a photo and open it in the gallery. Click on the sharing button (three connected dots), select the account you just created and click on share.
