Utility to collect the information of packages available in own repository. It is currently a primitive and raw version, and I wrote it quickly as I could not find any modules of this type to include in another project of mine (currently in private development). I will, however, be taking it forward in the next few days, at the same time as my other project which I plan to make public in a first version soon after the summer, in order to make it better in both code and functionality.
For anyone who happens to come here and finds this module useful and would like to help me, any contribution is welcome.
go-apt-search relies on files in the /var/lib/apt/lists path, these files are used to store information about each package resource specified in the system sources.list.
Specifically, files from which it extracts information are those in the format <source_of_repository>_Packages
Below is an example of how a package, with all its information, is shown in these files
Package: ctdb

Now only the essential information has been included, but all the others will be added.
The search can be performed in a precise manner, indicating the exact name of the package to be searched for, or search for all packages that include a certain string in their name. In the example case a search is performed for 0ad indicating that this is not a precise search
package main
import (
"fmt"
apt "github.com/cyberpsyquack/go-apt-search"
)
func main() {
fullPackagesList, errAptListAll := apt.AptListAll()
if errAptListAll != nil {
panic(errAptListAll)
}
searchResult, errAptSearch := apt.AptSearch("0ad", fullPackagesList, false)
if errAptSearch != nil {
panic(errAptSearch)
}
for _, singlePackage := range searchResult {
fmt.Printf("\n#### %s ####\n", singlePackage.PackageName)
fmt.Printf("Version: %s\n", singlePackage.Version)
fmt.Printf("Architecture: %s\n", singlePackage.Architecture)
