VOCAL hosts support for a couple different IDE’s, but there is really no mandatory development enviroment required. Here are a couple recommendations based on your platform 32-bit is a must for now, as much as we wish 64-bit would work out there are some dependencies we just can’t get rid of.
Window
PyCharm
PyCharm is also a super powerful IDE for developing, and the plus here is it offers tools that ensure you follow the correct programming practices as outlined in the Coding Conventions.
Eclipse
Eclipse is great IDE that offers some powerful tools, the VOCAL repository comes with a project file that allows for developers to easily load the project. See The Installation Page for steps on setting up Eclipse with VOCAL.
Linux
Console + VIM
If you’re a console loving guy, nothing is wrong with developing VOCAL using just the command line and the text editor of your choice (which should be VIM, right?)
PyCharm
Highly recommended, very easy to setup e.g. start the program and it’s all set up. As mentioned above great to ensuring you follow the coding conventions as listed above.
