UIOP feature idea...
What about adding a better FILE-LENGTH function to UIOP? I was looking at Peter Seibel's discussion of FILE-LENGTH in PCL. PiTA, and certainly unsuitable for use if one wants to write scripts in CL. What about making UIOP:FILE-LENGTH be generic and take either strings (filenames), pathnames, or streams as argument? cheers, r

Such a function probably fits in the library, though a bit less so if it is *not* used by ASDF. Please don't use a name that clashes with the CL package. The ASDF and UIOP tradition seems to suggest such a function should be named FILE-LENGTH*. I believe :element-type '(unsigned-byte 8) should be the default. I can review such a change that you write, or, if you're confident, you can just push the change and I can fix anything I don't like about it. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org If you think health care is expensive now, wait until you see what it costs when it's free. — P.J.

Or FILE-SIZE If you want to determine a "size" of a file without opening it (and counting newlines), then you're not considering a length (of a sequence, stored in the stream), but a file system file size.
