Re^5: Perl script compressor

And it is reducing perl code from 13,997 bytes to 4,750 bytes! That's less than half of the original. And we're not even using gzip here.

Even better, only 85% of the crippled code, 29% of the original code, and still lossless and maintainable:

/tmp>gzip -9 < 11109869.pl > 11109869.pl.gz
/tmp>lzma -9 < 11109869.pl > 11109869.pl.lzma
/tmp>bzip2 -9 < 11109869.pl > 11109869.pl.bz2
/tmp>dir 11109869.pl*

Okay, but if a perl script has to be unzipped before it can run, then this takes time. My compact perl code doesn’t modify the code’s structure or anything. It just removes spaces and renames variables. The perl script can run the same way, and no decompression is necessary.	[reply]

Your assessment is correct, but your bigger picture analysis is fundamentally flawed. You have already spent many orders of magnitude more of your time on this project than the total processor time likely to be saved over the lifetime of the code to be compressed. As davido has demonstrated the per-load time savings is completely inconsequential. Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond	[reply]

"My compact perl code doesn’t modify the code’s structure or anything. It just removes spaces and renames variables." It also doesn't address any of the problems you've decided exist, even though it's been it's been explained to you that your understanding of the process is wrong. But it's not the first time we've been in this situation.	[reply]
