[NTG-context] Analyze hyphenations

Hi, a couple of weeks ago Hans has implemented a tracker that adds a list of hyphentated words to the log file. I finally managed to play with this. The result is attached to this mail. This will permit analyzing hyphenations based on a ConTeXt log file. You need to enable hyphenation tracking in the ConTeXt file with \enabletrackers[hyphenation.applied]. Then, you can run the script with lua check-hyphens.lua input_file whitelist.ending As we assume .log for the input_file, the input file should be supplied without file ending. For the (optional) whitelist a file ending has to be supplied. Maybe I should wikify this, any suggestion where that would fit? HTH, Denis
