Hi Racketer
I'm trying to load a log file which size is 600MB, then I found the program
exhausted 3 GB resident memory just for load all the content of it via
(port->lines...). I do have enough RAM but it looks like some thing went
wrong here, and I do need to load them all into RAM for my use
Update with memory dump log attached.
1. With out (set! input empty), call (collect-garbage) doesn't help
2. Call (set! input empty) and (collect-garbage), memory reduce dramaticly.
; 214M(VIRT)/101M(RSS) without open any file
(let loop()
(sleep 5) ; Waiting here so that I can check it
Quick comment: of you don't need to load the whole file but want to parse
it line by line, use `in-lines` which is memory-efficient.

Thanks Laurent, I tried (in-lines...), and yes, it's memory-efficient, but
I still curious and concern why (port->lines ...) takes so many memory.
Best regards

port->lines produces a list with all the lines in it. That list is what
uses all the memory. Using in-lines avoids producing the whole list at
once.

Thank you, the problem was that I was defining f_0 as multiple patterns of*
(c_0 -> f_0)...* and only comparing it to one instance of f_0.

Hello,
I was reading your documentation for the Reduction Relations (4.4), and we
can use side-conditions and other extras like where and bind. But I cannot
implement them in my code. Can someone show me an example of how do I use
the clause *where*? For example, how do I verify that a variable
I opted for the read-syntax based solution. For those reading, it's convenient
to use `replace-context` from `syntax/strip-context` to donate lexical info.
The form of the transformer I used is:
@(define-syntax (reformat stx)
(replace-context stx
(read-syntax #f (open-input-string (with-output
Hi guys,
I’ve been racking my brains and going through scribble manuals trying to figure
out how to do something as simple as proceed a sentence like: The @ is used in
a scribble command. I’m sure I’m overlooking something very basic, since the @
is referenced all over scribble documentation.
See

I think you meant `@"@"`? `@["@"]` is an application.
