The code depends on the RST parser of the Nim compiler and on Jester. The code generating captchas for registration uses the cairo module, which requires you to have the cairo library installed when you run the forum, or you will be greeted by a cryptic error message similar to:

$ ./forum could not load:

Mac OS X


If you are using macosx and have installed the cairo library through MacPorts you still need to add the library path to your LD_LIBRARY_PATH environment variable. Example:

$ LD_LIBRARY_PATH=/opt/local/lib/ ./forum

Replace /opt/local/lib with the correct path on your system.


On macosx you also need to make sure to use the bcrypt >= 0.2.1 module if that is not yet updated you can install it with:

nimble install

You may also need to change nimforum.nimble such that it uses 0.2.1 by changing the dependencies slightly.

Requires: "nimrod >= 0.10.3, cairo#head, jester#head, bcrypt >= 0.2.1"

Running the forum

Important: You need to compile and run createdb to generate the initial database before you can run forum the first time!

Note: If you do not have a mail server set up locally, you can specify -d:dev during compilation to prevent nimforum from attempting to send emails and to automatically activate user accounts

This is as simple as:

nim c -r createdb

After that you can just run forum and if everything is ok you will get the info which URL you need to open in your browser (http://localhost:5000) to access it.

There is an update helper editdb which you can safely ignore for now.

The files captchas.nim, cache.nim are included by forum.nim and do not need to be compiled by you.
