If you're really into benchmarks, I'd love it if someone were to code up
|
||
|
|
the following problems in tcl, python, and scheme (and whatever else you'd
|
||
|
|
like). Separate versions (one optimized for speed, one for beauty :-) are
|
||
|
|
ok. Post your code so we can time it on our own systems.
|
||
|
|
|
||
|
|
0) Factorial Test (numerics and function calls)
|
||
|
|
|
||
|
|
(we did this already)
|
||
|
|
|
||
|
|
1) Regular Expressions Test
|
||
|
|
|
||
|
|
Read a file of (extended per egrep) regular expressions (one per line),
|
||
|
|
and apply those to all files whose names are listed on the command line.
|
||
|
|
Basically, an 'egrep -f' simulator. Test it with 20 "vt100" patterns
|
||
|
|
against a five /etc/termcap files. Tests using more elaborate patters
|
||
|
|
would also be interesting. Your code should not break if given hundreds
|
||
|
|
of regular expressions or binary files to scan.
|
||
|
|
|
||
|
|
2) Sorting Test
|
||
|
|
|
||
|
|
Sort an input file that consists of lines like this
|
||
|
|
|
||
|
|
var1=23 other=14 ditto=23 fred=2
|
||
|
|
|
||
|
|
such that each output line is sorted WRT to the number. Order
|
||
|
|
of output lines does not change. Resolve collisions using the
|
||
|
|
variable name. e.g.
|
||
|
|
|
||
|
|
fred=2 other=14 ditto=23 var1=23
|
||
|
|
|
||
|
|
Lines may be up to several kilobytes in length and contain
|
||
|
|
zillions of variables.
|
||
|
|
|
||
|
|
3) System Test
|
||
|
|
|
||
|
|
Given a list of directories, report any bogus symbolic links contained
|
||
|
|
anywhere in those subtrees. A bogus symbolic link is one that cannot
|
||
|
|
be resolved because it points to a nonexistent or otherwise
|
||
|
|
unresolvable file. Do *not* use an external find executable.
|
||
|
|
Directories may be very very deep. Print a warning immediately if the
|
||
|
|
system you're running on doesn't support symbolic links.
|
||
|
|
|
||
|
|
|
||
|
|
I'll post perl solutions if people post the others.
