Package: apt
Version: 1.8.2.1
Severity: normal
I've completely switched to using "apt" for all debian package management. I'm
fine with the "apt" tool, it fits all my needs except one... serarching.
For example I look for package to read/write JSON data in perl. In old days I
used the command "apt-cache search" like this:
leszek@len530:~$ apt-cache search perl | egrep JSON | egrep -i data
and the result was simple:
libjson-perl - module for manipulating JSON-formatted data
libjson-xs-perl - module for manipulating JSON-formatted data
(C/XS-accelerated)
libcatmandu-importer-getjson-perl - load JSON-encoded data from a
server using a GET HTTP request
libjson-pp-perl - module for manipulating JSON-formatted data (Pure
Perl)
libjson-validator-perl - module to validate data against a JSON schema
libtest-deep-json-perl - Test::Deep plugin for comparing JSON data
libtest-json-perl - module for testing JSON data
Because "apt search" (not "apt-cache search", just "apt") shows each package on
two lines, then grepping results is not possible.
I've looked at man pages, internet sites to find soultion. Other people have the
same problem.
The soultion is to change "apt search" output:
leszek@len530:~$ apt search perl JSON data
from:
libxml-atom-microformats-perl/focal,focal 0.004-3 all
parse microformats in Atom content
php-json-schema/focal,focal 5.2.9-1 all
implementation of JSON schema
php-services-json/focal,focal 1.0.3-1build1 all
PHP implementaion of json_encode/decode
vim-syntastic/focal,focal 3.10.0-2 all
Syntax checking hacks for vim
to:
libxml-atom-microformats-perl/focal,focal 0.004-3 all parse
microformats in Atom content
php-json-schema/focal,focal 5.2.9-1 all implementation of JSON schema
php-services-json/focal,focal 1.0.3-1build1 all PHP implementaion of
json_encode/decode
vim-syntastic/focal,focal 3.10.0-2 all Syntax checking hacks for vim
It would make life lot easier.
