Re^4: Bit string manipulation made easy with Bit::Manip

Bingo!

While not necessary, it seems that clr would complete the API. As an old assembly coder, I think in terms of setting, clearing and flipping/toggling bits.

As a minor nit pick... Setting a bit "on" or "off" doesn't tell you if the hardware is turning a device "on" or "off". Depends on how the designer set up the hardware. Active high? Active low? Could be either.

I have added in a new function, `bit_clr()`, which will clear a range of bits: `bit_clr($int, $lsb, $nbits);`. Here's a small sample of my test file. This functionality will be available in the next release. Thanks for the suggestion! Sample part of test file: `is bit_bin(bit_clr(255, 0, 8)), '0', "255, 0, 8 ok"; is bit_bin(bit_clr(255, 0, 2)), '11111100', "255, 0, 2 ok"; is bit_bin(bit_clr(255, 0, 3)), '11111000', "255, 0, 3 ok"; is bit_bin(bit_clr(255, 0, 4)), '11110000', "255, 0, 4 ok"; is bit_bin(bit_clr(255, 3, 1)), '11110111', "255, 3, 1 ok"; is bit_bin(bit_clr(255, 3, 2)), '11100111', "255, 3, 2 ok"; is bit_bin(bit_clr(255, 3, 3)), '11000111', "255, 3, 3 ok"; is bit_bin(bit_clr(255, 7, 1)), '1111111', "255, 7, 1 ok";` [download]	[reply] [d/l] [select]
