I started using wiki at work and over the years it became one of the tool that i daily use. I started to use wiki personally for myself to capture design thoughts, todos, planning items and organizing all my files (importing into wiki folder) with some context descriptions making it a mashup or portal. I use wikidpad and dropbox to sync this with all my machines (mac and windows). This is DIY alternative to Evernote or Things. I don’t want my unencrypted data on cloud. In fact it is very easy to turn this tool into whatever you want as a personal doc portal/GTD/planner etc., Installing on mac is pain and more pain if you are on 64 bit. This is because it is based on wxPython which is based on Carbon for mac and they are supported only for 32 bit.
Here are some of my tips to install on mac and is based on the shell script provided by them.
1. Python 2.6 (comes with mac and is enabled by default as 64 bit if your kernel is 64).
2. Install wxPython 2.8 for 2.6. Just use the dmg.
3. Download the WikidPad source and copy into your preferred location. Like in my case ~/tools/
4. Create a shell script that does the following…
1. set the python to run in 32 bit mode for that session using “export VERSIONER_PYTHON_PREFER_32_BIT=yes”.
2. cd to the directory of the Wikidpad source.
3. start WikidPad: python WikidPad.py
Use the shell script to start wikidpad and create wiki files under dropbox sync directories so that it is synced to all your machines. The nice thing is that the wiki creates a .lock file and warns if you accidentally edit the same wiki from two places.
Note: If you by default run on the 32 bit python then just follow the steps for users which will avoid all the above steps and create you a nice app. I guess they use py2app for this.
