large files repo Yes, the regular expression used in the largerepo-tree.ps1 script will work correctly with repository names containing hyphens (-) and underscores (_). Character Classes: The regular expression uses [^\/]+ to match one or more characters that are not a forward slash (/). This character class includes hyphens and underscores, as well as letters, numbers, and most other symbols. Specific Parts: The relevant part of the regex is (https:\/\/github\.com\/[^\/]+\/[^\/]+). This is designed to capture the https://github.com/owner/repo portion of the URL. The [^\/]+ parts will match any character except a forward slash, which is exactly what you need to handle hyphens and underscores in the repository owner and repository name. Example Scenarios: Let's say you have these repository URLs: https://github.com/my-org/my_repo/tree/main/frontend https://github.com/my_org-test/my-repo_project/tree/develop/backend/api The script will successfully parse these URLs and extract the correct repository URL, branch, and sparse path. Testing: To verify, you can create a test repository with hyphens and underscores in the name and try running the script with a tree URL from that repository. In conclusion, the largerepo-tree.ps1 script is robust enough to handle repository names containing hyphens and underscores. # largerepo-tree.ps1 param ( [Parameter(Mandatory=$true, HelpMessage="Repository tree URL (e.g., https://github.com/largeorg/monorepo/tree/main/frontend)")] [string]$TreeUrl ) try { # Extract repository URL, branch, and sparse path from the tree URL if ($TreeUrl -match "^(https:\/\/github\.com\/[^\/]+\/[^\/]+)\/tree\/([^\/]+)\/(.+)$") { $repoUrl = $Matches[1] + ".git" $branch = $Matches[2] $sparsePath = $Matches[3] } else { throw "Invalid tree URL format.
