Add author field to library search scope

[per1234]

Describe the request

Add the author field of the library index to the search scope of the arduino-cli lib search command.

🙂 The chances of finding a library by searching for the name of its author will be increased.

  Sentence: The FlashStorage library aims to provide a convenient way to store and retrieve user's data using the non-volatile flash memory of SAMD21/SAMD51. It's using the buffered read and write to minimize the 
access to Flash. It now supports writing and reading the whole object, not just byte-and-byte.

Describe the current behavior

The scope of arduino-cli lib search is the following fields of the library index:

arduino-cli/commands/lib/search.go

Line 44 in 5730e2e

toTest := []string{lib.Name, lib.Latest.Paragraph, lib.Latest.Sentence}

• name
• sentence
• paragraph

The author field of the library.properties metadata file of Arduino libraries contains the name of the author(s) of the library.

🙁 It is difficult to find libraries by searching for the author name.

Issue checklist

• I searched for previous requests in the issue tracker
• I verified the feature was still missing when using the latest nightly build
• My request contains all necessary details

[tablatronix]

Thanks for reposting for me, it seems the library manager also only shows one author which can also be problematic. So fixing both the display in the ide and helping with search inside the ide lib manager

Hi @tablatronix

it seems the library manager also only shows one author which can also be problematic

I think you are referring to a bug specific to Arduino IDE 1.x, as reported in your issue as well as others:

• Library manager and multiple authors can be problematic Arduino#11679
• library.properties "Developer" field information is rendering both old and new variants in Library Manager. Arduino#11618
• Boards manager: wrong description shown arduino-ide#1493

However, I can not reproduce this in Arduino CLI and Arduino IDE 2.x:

$ arduino-cli lib search FlashStorage_SAMD

If you are able to reproduce it with either Arduino CLI or Arduino IDE 2.x, please do submit a bug report about that.

I did not know about ide 2.x ill test it
