@pmienk@evoskuil I like consistency :P. As far as I see, gsl scripts stick to the principle "Maximum of 80 characters per line". What to do in this case? https://github.com/libbitcoin/libbitcoin-build/blob/master/templates/gsl.version.hpp#L44 Possible solutions: 1. leave it as it is and break the rule. 2. additional variable and break the string interpolation https://pastebin.com/94JMsXr1 3. additional variable and leave the string in one line https://pastebin.com/QNDVWyvx 4. continue by 1 indent https://pastebin.com/95WgL3se The last case (4) is something like a "fake" because there is no indent but the indent a part of the template output. Case 1 breaks the rule. Case 2 and 3 looks good for me.
