LeanSearchClient

In this file, we provide syntax for search using the leansearch API and the Moogle API. from within Lean. It allows you to search for Lean tactics and theorems using natural language.

We provide syntax to make a query and generate TryThis options to click or use a code action to use the results.

The queries are of three forms. For leansearch these are:

• Command syntax: #leansearch "search query" as a command.
• Term syntax: #leansearch "search query" as a term.
• Tactic syntax: #leansearch "search query" as a tactic.

The corresponding syntax for Moogle is:

• Command syntax: #moogle "search query" as a command.
• Term syntax: #moogle "search query" as a term.
• Tactic syntax: #moogle "search query" as a tactic.

In all cases results are displayed in the Lean Infoview and clicking these replaces the query text. In the cases of a query for tactics only valid tactics are displayed.
