✨ NAME ✨

arduino-cli-lib-upgrade — upgrades installed libraries.

like, it takes your dusty old libs and gives them a whole new era. 💅

---

🌸 SYNOPSIS 🌸

arduino-cli lib upgrade [flags]

that's it. that's the whole vibe. command, [flags], done.

---

🦋 DESCRIPTION 🦋

so here's the tea: this command upgrades an installed library to the latest available version. latest available, no cap.

you can pass multiple libraries, separated by a space — go off, queue them all up.

and if you pass no arguments at all? the command will upgrade all the installed libraries where an update is available. not every single lib, bestie — just the ones that actually have an update waiting. it does the vibe check for you. ✨

---

🎀 OPTIONS 🎀

• -h, --help[=false] — help for upgrade. your little "wait what does this do" button. 🙈

---

💜 OPTIONS INHERITED FROM PARENT COMMANDS

these are the ones you didn't ask for but got anyway, because family. (the parent command said "you're taking these with you.") 🫶

• --additional-urls=[] — Comma-separated list of additional URLs for the Boards Manager.
• --config-dir="" — Sets the default data directory (Arduino CLI will look for configuration file in this directory).
• --config-file="" — The custom config file (if not specified the default will be used).
• --json[=false] — Print the output in JSON format.
• --log[=false] — Print the logs on the standard output.
• --log-file="" — Path to the file where logs will be written.
• --log-format="text" — The output format for the logs, can be: text, json
• --log-level="info" — Messages with this level and above will be logged. Valid levels are: trace, debug, info, warn, error, fatal, panic
• --no-color[=false] — Disable colored output.

ngl the default log level is info, so if you're like "where are my logs" — that's why. turn it down to debug or trace if you want the full director's cut. 👑

🌈 EXAMPLE 🌈

here's exactly how it looks in the wild, character for character:

debian/build/bin/arduino-cli lib upgrade
