Dealing with Libraries

There are mulitple ways of handling libraries in arduino-cli. This example will use LiquidCrystal_I2C as the library.

By name

• Installing a library by name:

$ arduino-cli lib install "LiquidCrystal_I2C"

If you are unsure about the exact name of the library, you can search:

$ arduino-cli lib search liquidcrystal

• Unstalling a library by name:

$ arduino-cli lib uninstall "LiquidCrystal_I2C"

• Listing all installed libraries:

$ arduino-cli lib list

You can use grep to "search" for a specific installed library:

$ arduino-cli lib list | grep LiquidCrystal_I2C

• Updating libraries (by name):

Updating all installed libraries:

$ arduino-cli lib upgrade

Updating a specific library:

$ arduino-cli lib upgrade LiquidCrystal_I2C

Manually

If you need a library which is not in the standard list, e.g. your own library, a very new or unknown library, you can manually put (or e.g. git clone) the library in your user's library folder:

$ cd ~/Arduino/libraries

There you can also just delete, edit or replace it to update / uninstall.
