Hello,
I'm trying to write a while loop for a decimal value in tcsh which I know can't be done. Instead I want my increments to be one order of magnitude too large and then divide it by 10 when I use the variable. However, I don't know how to divide my variable and set it as another.

Hi All
I've made a few scripts which using GDAL extract the value of a pixel within a given raster. The purpose is to work out the combine value of every pixel. I thought there may have been an easier way to do this but alas!
The code below extracts the pixel value at position X Y. The... (3 Replies)

Hi,
Need help on this. I need to increment a variable by 1 but retain as 2 characters.
I am using expr to do additions:
NEWSERIAL=`expr $SERIAL + 1`
$SERIAL can range from 01-99. After adding "1", I need the result to be 2 characters, eg: 02+1 = 03. By default expr will truncate the... (4 Replies)

css::packer
CSS::Packer(3pm) User Contributed Perl Documentation CSS::Packer(3pm)
NAME
CSS::Packer - Another CSS minifier
VERSION
Version 1.002001
DESCRIPTION
A fast pure Perl CSS minifier.
SYNOPSIS
use CSS::Packer;
my $packer = CSS::Packer->init();
$packer->minify( $scalarref, $opts );
To return a scalar without changing the input simply use (e.g. example 2):
my $ret = $packer->minify( $scalarref, $opts );
For backward compatibility it is still possible to call 'minify' as a function:
CSS::Packer::minify( $scalarref, $opts );
First argument must be a scalarref of CSS-Code. Second argument must be a hashref of options. Possible options are:
compress
Defines compression level. Possible values are 'minify' and 'pretty'. Default value is 'pretty'.
'pretty' converts
a {
color: black
;} div
{ width:100px;
}
to
a{
color:black;
}
div{
width:100px;
}
'minify' converts the same rules to
a{color:black;}div{width:100px;}
copyright
You can add a copyright notice at the top of the script.
remove_copyright
If there is a copyright notice in a comment it will only be removed if this option is set to a true value. Otherwise the first comment
that contains the word "copyright" will be added at the top of the packed script. A copyright comment will be overwritten by a
copyright notice defined with the copyright option.
no_compress_comment
If not set to a true value it is allowed to set a CSS comment that prevents the input being packed or defines a compression level.
/* CSS::Packer _no_compress_ */
/* CSS::Packer pretty */
