Needed to build a feature for a Bookstore tool to have an optional sequence number for the Custom Post Type “books” that would allow items with a seq number to float to the top of the list and be sorted by seq #. The rest of the books would show underneath, sorted alphabetically.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
$querytop = get_posts(array( 'post_type' => 'books', 'numberposts' => -1, 'orderby' => 'meta_value', 'meta_key' => 'book_seq', 'order' => 'ASC', 'meta_query' => array( // meta query takes an array of arrays, watch out for this! array( 'key' => 'book_seq', 'value' => array('', 'NULL'), 'compare' => 'NOT IN' ) ) )); $querybottom = get_posts(array( 'post_type' => 'books', 'numberposts' => -1, 'orderby' => 'post_title', 'order' => 'ASC', 'meta_query' => array( // meta query takes an array of arrays, watch out for this! array( 'key' => 'book_seq', 'compare' => 'NOT EXISTS' ) ) )); $query = array_merge($querytop, $querybottom); |

I wanted to call a sub-routine based on a variable in Perl, like this:
|
|
our $role = 'master'; &$role; |
but it failed because of use strict:
|
|
Can't use string ("master") as a subroutine ref while "strict refs" in use at /opt/continuent/tungsten/tools/tungsten_find_orphaned line 213. |
To enable using a variable as a reference, simply specify that to Perl:
|
|
use strict no strict "refs"; |

Every time I use awk, my respect for it grows! Like grep, find and rsync, it is one of the powerhouse command-line tools in my arsenal. Recently, I needed to list all MySQL binary log files from a starting file forwards in sequence. AWK to the rescue! For example, I knew the starting file was […]

While using Confluence, I wanted to learn how to add a simple task checkbox in free-flow text and lists without creating a “real” task. The answer is very easy – just type the square bracket pair [] and the checkbox will appear!

When I upgraded to Mojave, my laptops were no longer able to connect to my desktop. Deeply frustrating. Long story short, combo of factors: – Mojave filesystems on disk now default to APFS containers – APFS filesystems can ONLY be shared out via SMB! – Hostname resolution in Mojave also seems broken So, the fix […]

The Problem Tried to install the latest version of cpan and got stuck. Tracked it down to the dependency module Mac::SystemDirectory which was failing to build:

The Solution Use the MacOS installer command to deploy the needed files:
|
|
sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target / installer: Package name is macOS_SDK_headers_for_macOS_10.14 installer: Installing at base path / installer: The install was successful. |
The, rerunning the cpan install works:
|
