Walkthrough

The script public/celestia-app.sh has been updated to use curl instead of wget for downloading files. The installation flow has been revised: after extracting the binary, the script now checks for the presence of Go and offers a multi-choice prompt to select the installation location for the celestia-appd binary. Based on the user's selection, the script moves or retains the binary, sets permissions, and creates a symlink. It also checks if the Go bin directory is in the user's PATH and provides tailored instructions for running the binary.

Poem

🐇
With curl I hop, no more wget to fetch,
Choices for install—just follow my sketch!
Go or no Go, I sniff out your bin,
A symlink I leave, with a wink and a grin.
Now running Celestia is easy as pie,
Just follow my prompts—give it a try!

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
