reading s-expressions from a file
by Alexandre Rademaker 26 Jun '19

The “read” function makes really easy to read a bunch of s-expressions from a file, but how can I keep track of the line number where the expressions were in the file? Any ideia? Alexandre Sent from my iPhone

Alexandre, be careful with Lisp control characters embedded - back quotes, commas etc. Jack Harper Secure Outcomes Inc Evergreen, Colorado USA At 10:27 AM 6/26/2019, LuÃs Oliveira wrote: >On Wed, Jun 26, 2019 at 5:19 PM Alexandre Rademaker ><arademaker(a)gmail.com> wrote: > > The âreadâ function makes really easy to > read a bunch of s-expressions from a file, but > how can I keep track of the line number where the expressions were in the file? > >One way to do it is to define a stream that keeps track of the current >line.

Hi if you don’t load code that implements a feature you wouldn’t be able to push a feature onto the *FEATURES* list. That is, unless you are a jerk :) :) :) and push stuff onto the *FEATURES* list just for the heck of it, or as a, I’d say tasteless, joke :) :) :) Cheers MA > On May 12, 2019, at 22:04 , Michael Raskin <38a938c2(a)rambler.ru> wrote: > > Hello > I look at CDR-14 that says about putting :CDR-NN symbols into > *features* if implementation purports to implement a CDR.
