stdin input restrictions
stdin input restrictions
I need to get from input stream a lot of numbers (400+), separated by space. Testing in small amounts, manually (up to 100 numbers) - everything is ok. Coping input batch of 100 numbers to console prompt - everything is OK. But if I take 200 number (for example), it freezes and has any response. Is it some restriction on input stream?

Re: stdin input restrictions
Which platform, which implementation, and some code to show what you are doing would help me help you.

OSX Mojave, Implementation - SBCL 1.4.16.21-825d4d007
Sample code smtg like this
Code: Select all
(defvar *data* '())
(defun read-data()
(loop

(push (read) *data*)))
(read-data)
(format t "~%Array:~%~{~A ~}~%End array~%" *data*)

Re: stdin input restrictions
If you are pasting into the terminal then you may be hitting the maximum size of the clipboard, if your code is run with stdin from a file it works-for-me
But if I try to copy from an emacs buffer into the terminal then it stops at 1000127, and I assume it is hanging because it is waiting for the remaining numbers
Code: Select all
