Request for review of my string to float function

Hi, While working on the json library I had to write a string to float function. In a list of characters when I encounter a digit, I'd like to go over the rest of the list and consume all the digits (and possibly a period) that form a number. I'd appreciate some feedback from a Lispiness and

Re: Waiting for a forked child to finish

Thanks Alex, I am trying to download a bunch of URLs in parallel and wait until all the downloads have finished before proceeding. Calling (kill Pid 0) seems reasonable. Regards, Kashyap On Sat, May 11, 2019 at 11:24 AM Alexander Burger wrote: > Hi Kashyap, > > > How can I wait for a forked

Re: A quick way to write an http endpoint to handle post body

Super! ... almost what I was looking for I mean one minor fix is that I have to call a (line) after (read) to read up the newline after the content length. Also, I need to figure out how to capture the body do I do a pipe? Regards, Kashyap On Sat, May 18, 2019 at 11:53 AM Alexander

Re: A quick way to write an http endpoint to handle post body

Hey Alex, While my question was about the server side - it is super cool to learn about "ssl" - although I am curious - was there a reason why "POST" was left out of it? Also I agree about the point of parsing a program generated JSON looks like an overkill is many cases. Hey Andreas - I dont
