//! # Development Environment Advice
//!
//! Large Rust projects are known for sometimes long compile times and sluggish dev tooling, and
//! pezkuwi-sdk is no exception.
//!
//! This page contains some advice to improve your workflow when using common tooling.
//!
//! ## Rust Analyzer Configuration
//!
//! [Rust Analyzer](https://rust-analyzer.github.io/) is the defacto [LSP](https://langserver.org/) for Rust. Its default
//! settings are fine for smaller projects, but not well optimised for pezkuwi-sdk.
//!
//! Below is a suggested configuration for VSCode or any VSCode-based editor like Cursor:
//!
//! ```json
//! {
//!   // Use a separate target dir for Rust Analyzer. Helpful if you want to use Rust
//!   // Analyzer and cargo on the command line at the same time,
//!   // at the expense of duplicating build artifacts.
//!   "rust-analyzer.cargo.targetDir": "target/vscode-rust-analyzer",
//!   // Improve stability
//!   "rust-analyzer.server.extraEnv": {
//!     "CHALK_OVERFLOW_DEPTH": "100000000",
//!     "CHALK_SOLVER_MAX_SIZE": "10000000"
//!   },
//!   // Check feature-gated code
//!   "rust-analyzer.cargo.features": "all",
//!   "rust-analyzer.cargo.extraEnv": {
//!     // Skip building WASM, there is never need for it here
//!     "SKIP_WASM_BUILD": "1"
//!   },
//!   // Don't expand some problematic proc_macros
//!   "rust-analyzer.procMacro.ignored": {
//!     "async-trait": ["async_trait"],
//!     "napi-derive": ["napi"],
//!     "async-recursion": ["async_recursion"],
//!     "async-std": ["async_std"]
//!   },
//!   // Use nightly formatting.
//!   // See the pezkuwi-sdk CI job that checks formatting for the current version used in
//!   // pezkuwi-sdk.
//!   "rust-analyzer.rustfmt.extraArgs": ["+nightly-2024-04-10"],
//! }
//! ```
//!
//! and the same in Lua for `neovim/nvim-lspconfig`:
//!
//! ```lua
//! ["rust-analyzer"] = {
//!   rust = {
//!     # Use a separate target dir for Rust Analyzer. Helpful if you want to use Rust
//!     # Analyzer and cargo on the command line at the same time.
//!     analyzerTargetDir = "target/nvim-rust-analyzer",
//!   },
//!   server = {
//!     # Improve stability
//!     extraEnv = {
//!       ["CHALK_OVERFLOW_DEPTH"] = "100000000",
//!       ["CHALK_SOLVER_MAX_SIZE"] = "100000000",
//!     },
//!   },
//!   cargo = {
//!     # Check feature-gated code
//!     features = "all",
//!     extraEnv = {
//!       # Skip building WASM, there is never need for it here
//!       ["SKIP_WASM_BUILD"] = "1",
//!     },
//!   },
//!   procMacro = {
//!     # Don't expand some problematic proc_macros
//!     ignored = {
//!       ["async-trait"] = { "async_trait" },
//!       ["napi-derive"] = { "napi" },
//!       ["async-recursion"] = { "async_recursion" },
//!       ["async-std"] = { "async_std" },
//!     },
//!   },
//!   rustfmt = {
//!     # Use nightly formatting.
//!     # See the pezkuwi-sdk CI job that checks formatting for the current version used in
//!     # pezkuwi-sdk.
//!     extraArgs = { "+nightly-2024-04-10" },
//!   },
//! },
//! ```
//!
//! Alternatively for neovim, if you are using [Rustaceanvim](https://github.com/mrcjkb/rustaceanvim),
//! you can achieve the same configuring `rust-analyzer` via `rustaceanvim` as follows:
//! ```lua
//! return {
//!  {
//!    "mrcjkb/rustaceanvim",
//!    opts = {
//!      server = {
//!        default_settings = {
//!           ["rust-analyzer"] = {
//!            // put the same config as for nvim-lspconfig here
//!          },
//!        },
//!      },
//!    },
//!  },
//! }
//! ```
//!
//! Similarly for Zed, you can replicate the same VSCode configuration  in
//! `~/.config/zed/settings.json` as follows:
//! ```json
//! "lsp": {
//!   "rust-analyzer": {
//!     "initialization_options": {
//!       // same config as for VSCode for rust, cargo, procMacros, ...
//!     }
//!   }
//! },
//! ```
//!
//! In general, refer to your favorite editor / IDE's documentation to properly configure
//! `rust-analyzer` as language server.
//! For the full set of configuration options see <https://rust-analyzer.github.io/manual.html#configuration>.
//!
//! ## Cargo Usage
//!
//! ### Using `--package` (a.k.a. `-p`)
//!
//! pezkuwi-sdk is a monorepo containing many crates. When you run a cargo command without
//! `-p`, you will almost certainly compile crates outside of the scope you are working.
//!
//! Instead, you should identify the name of the crate you are working on by checking the `name`
//! field in the closest `Cargo.toml` file. Then, use `-p` with your cargo commands to only compile
//! that crate.
//!
//! ### `SKIP_WASM_BUILD=1` environment variable
//!
//! When cargo touches a runtime crate, by default it will also compile the WASM binary,
//! approximately doubling the compilation time.
//!
//! The WASM binary is usually not needed, especially when running `check` or `test`. To skip the
//! WASM build, set the `SKIP_WASM_BUILD` environment variable to `1`. For example:
//! `SKIP_WASM_BUILD=1 cargo check -p pezframe-support`.
//!
//! ### Cargo Remote
//!
//! Warning: cargo remote by default doesn't transfer hidden files to the remote machine. But hidden
//! files can be useful, e.g. for sqlx usage. On the other hand using `--transfer-hidden` flag will
//! transfer `.git` which is big.
//!
//! If you have a powerful remote server available, you may consider using
//! [cargo-remote](https://github.com/sgeisler/cargo-remote) to execute cargo commands on it,
//! freeing up local resources for other tasks like `rust-analyzer`.
//!
//! When using `cargo-remote`, you can configure your editor to perform the the typical
//! "check-on-save" remotely as well. The configuration for VSCode (or any VSCode-based editor like
//! Cursor) is as follows:
//!
//! ```json
//! {
//! 	"rust-analyzer.cargo.buildScripts.overrideCommand": [
//! 		"cargo",
//! 		"remote",
//! 		"--build-env",
//! 		"SKIP_WASM_BUILD=1",
//! 		"--",
//! 		"check",
//! 		"--message-format=json",
//! 		"--all-targets",
//! 		"--all-features",
//! 		"--target-dir=target/rust-analyzer"
//! 	],
//! 	"rust-analyzer.check.overrideCommand": [
//! 		"cargo",
//! 		"remote",
//! 		"--build-env",
//! 		"SKIP_WASM_BUILD=1",
//! 		"--",
//! 		"check",
//! 		"--workspace",
//! 		"--message-format=json",
//! 		"--all-targets",
//! 		"--all-features",
//! 		"--target-dir=target/rust-analyzer"
//! 	],
//! }
//! ```
//!
//! and the same in Lua for `neovim/nvim-lspconfig`:
//!
//! ```lua
//! ["rust-analyzer"] = {
//!   cargo = {
//!     buildScripts = {
//!       overrideCommand = {
//!         "cargo",
//!         "remote",
//!         "--build-env",
//!         "SKIP_WASM_BUILD=1",
//!         "--",
//!         "check",
//!         "--message-format=json",
//!         "--all-targets",
//!         "--all-features",
//!         "--target-dir=target/rust-analyzer"
//!       },
//!     },
//!   },
//!   check = {
//!     overrideCommand = {
//!       "cargo",
//!       "remote",
//!       "--build-env",
//!       "SKIP_WASM_BUILD=1",
//!       "--",
//!       "check",
//!       "--workspace",
//!       "--message-format=json",
//!       "--all-targets",
//!       "--all-features",
//!       "--target-dir=target/rust-analyzer"
//!     },
//!   },
//! },
//! ```
