You can add special ignore files to the directories you are scanning, if you want to ignore generated files or config files or other irrelevant bits. See the scanner howto for more details.
I must admit I have been wildly inconsistent here - but I'm not alone.
Wikipedia has a pile of information here - as they say:
The -ize spelling is often incorrectly seen as an Americanism in Britain. It has been in use since the 15th century, predating -ise by over a century.
However - language is defined by culture, usage, and readers, not by history. I was brought up Australian, and am now living in the UK and on the path to dual citizenship - so I want to use British english, not due to anti-American sentiment, just because I like to use the language of the place where I live.
The Wikipedia article indicates "The ratio between -ise and -ize stood at 3:2 in the British National Corpus up to 2002" - and while the OUP and Oxford style guides suggest 'ize', they are outnumbered by other organisations.
Most importantly, I'm a huge fan of the UK Government Digital Services, and their style guide is good enough for me:
... use ‘organise’ not ‘organize’, ‘modelling’ not ‘modeling’, and ‘fill in a form’, not ‘fill out a form’.
TL;DR: I'm using 'visualise' and 'visualisation'Edit this page on GitHub
