Research direction

Read the repository's existing organization for programming tips first; the issue provides the complete listTags shell function and its bash/zsh placement. Done means documenting that snippet in the appropriate tip location and preserving its stated usage for Docker image tags.

Written by the indexing model from the issue text.

Description

Put the following script to ~/.bashrc or ~/.zshrc for bash, zsh respectively.

Then you can run listTags gogs/gogs, or listTags ubuntu to list docker image tags from the docker repository.

 function listTags() {
     local repo=${1}
     local size=${2:-25}
     local page=${3:-1}
     [ -z "${repo}" ] && echo "Usage: listTags <repoName> [size] [pageIndex]" 1>&2 && return 1
     if [[ $repo == *"/"*  ]]; then
         curl "https://hub.docker.com/v2/repositories/${repo}/tags/?page=${page}&page_size=${size}" 2>/dev/null | jq -r '.results[].name' |     sort
     else
         curl "https://registry.hub.docker.com/api/content/v1/repositories/public/library/${repo}/tags?page=${page}&page_size=${size}" 2>/dev/null | jq -r '.results[].name' | sort
     fi
 }
