| 411 | ## ๐ Usage |
| 412 | |
| 413 | This plugin can be initiated in two ways: |
| 414 | |
| 415 | - To start [leetcode.nvim], simply pass [`arg`](#arg) |
| 416 | as the _first and **only**_ [Neovim] argument |
| 417 | |
| 418 | ``` |
| 419 | nvim leetcode.nvim |
| 420 | ``` |
| 421 | |
| 422 | - _**(Experimental)**_ Alternatively, you can use `:Leet` command to open [leetcode.nvim] |
| 423 | within your preferred dashboard plugin. The only requirement is that [Neovim] |
| 424 | must not have any listed buffers open. |
| 425 | |
| 426 | ### Switching between questions |
| 427 | |
| 428 | To switch between questions, use `Leet tabs` |
| 429 | |
| 430 | ### Sign In |
| 431 | |
| 432 | It is **required** to be **signed-in** to use [leetcode.nvim] |
| 433 | |
| 434 | https://github.com/kawre/leetcode.nvim/assets/69250723/b7be8b95-5e2c-4153-8845-4ad3abeda5c3 |
| 435 | |
| 436 | ## ๐ด Recipes |
| 437 | |
| 438 | ### ๐ค lazy loading with [lazy.nvim] |
| 439 | |
| 440 | > [!WARNING] |
| 441 | > opting for either option makes the alternative |
| 442 | > launch method unavailable due to lazy loading |
| 443 | |
| 444 | - with [`arg`](#arg) |
| 445 | |
| 446 | ```lua |
| 447 | local leet_arg = "leetcode.nvim" |
| 448 | ``` |
| 449 | |
| 450 | ```lua |
| 451 | { |
| 452 | "kawre/leetcode.nvim", |
| 453 | lazy = leet_arg ~= vim.fn.argv()[1], |
| 454 | opts = { arg = leet_arg }, |
| 455 | } |
| 456 | ``` |
| 457 | |
| 458 | - with `:Leet` |
| 459 | |
| 460 | ```lua |
| 461 | { |
| 462 | "kawre/leetcode.nvim", |
| 463 | cmd = "Leet", |
| 464 | } |
| 465 | ``` |
| 466 | |
| 467 | ## ๐งฉ Plugins |
| 468 | |
| 469 | ### Non-Standalone mode |
| 470 | |
| 471 | To run [leetcode.nvim] in a non-standalone mode (i.e. not with argument or an empty Neovim session), |
| 472 | enable the `non_standalone` plugin in your config: |
| 473 | |
| 474 | ```lua |
| 475 | plugins = { |
| 476 | non_standalone = true, |
| 477 | } |
| 478 | ``` |
| 479 | |
| 480 | You can then exit [leetcode.nvim] using `:Leet exit` command |
