Update (2008.3/5) : More Information is in Trac. Please check and see the latest version there. Text below is about version 1.0, and current version is 1.4 including more features.
I wrote a small Quicksilver plugin to send messages to Twitter directly.
Advantages
- Easy to install. No additional software required to be installed
- Configurable via Quicksilver Preference
- You can send messages containing non-ASCII characters
Download
QSTwitter.zip (1.2) (2008.01.23)
Environment
Tested under Leopard 10.5.1, Quicksilver B53 3814.
Install
Unzip the downloaded file and double-click it. that’s all !
Configuration
You will find “Twitter option” in the Quicksilver preference pane. Enter your screen name and password there.
Usage
- Activate Quicksilver (by Ctrl-SPACE or so)
- type . (period/dot) key to enter text input mode
- type a message
- hit TAB to move into Action
- type “Twitter”
- return !
The more familar you are with it, the faster you can send messages than ever.
Screencast
Seeing is Believing, as you know :) I don’t know why the video is collapsing for first 15 seconds. Sorry for inconvinience.
Code
You can see the code in CodeRepos.
License
Considering…
Restriction
- I could not post messages throught HTTP proxy. Let me know if anyone succeeded to make it.
ChangeLog
- 1.2 (2008.01.23) : fixes the bug that ‘+’ is not shown in status, uses pretty girl icon .
- 1.1 (2007.12.22) : now it shows “QSTwitter” in your post on “from …” .
- 1.0 (2007.12.13) : initial release.
There seems no comprehensive documents to develop Quicksilver plugin as far as I searched. In order to share my experience to avoid falling into pitfalls, I will write an tutorial developing a Quicksilver plugin under up-to-date environment later.
