How to disable check on save ?

[mateuszaaa]

Is it possible to disable check on save, i would rather prefer triggering it manually

Hey 👋

Yes. See Fly check in the readme's Usage section.

hi, thanks for quick responde but even though i have checkOnSave set to false whenever i save the file i can see that cargo clippy is tiggered

  {
    "mrcjkb/rustaceanvim",
    enabled = true,
    version = "^4", -- Recommended
    ft = { "rust" },
    keys = {
      { "<leader>rc", "<cmd>RustLsp openCargo<cr>", desc = "Open Cargo" },
      { "<leader>rs", "<cmd>LspStart<cr>", desc = "LspStart" },
      { "<leader>rR", "<cmd>LspRestart<cr>", desc = "LspRestart" },
      { "<leader>rS", "<cmd>LspStop<cr>", desc = "LspStop" },
      { "<leader>rr", "<cmd>RustLsp runnables<cr>", desc = "Rust runables" },
      { "<leader>rt", "<cmd>RustLsp testables<cr>", desc = "Rust tests" },
      { "<leader>rd", "<cmd>RustLsp debuggables<cr>", desc = "Rust debuggables" },
    },
    default_settings = {
      -- rust-analyzer language server configuration
      ["rust-analyzer"] = {
        cargo = {
          allFeatures = false,
          loadOutDirsFromCheck = true,
          runBuildScripts = false,
        },
        -- Add clippy lints for Rust.
        checkOnSave = false,
        procMacro = {
          enable = true,
          ignored = {
            -- ["async-trait"] = { "async_trait" },
            -- ["napi-derive"] = { "napi" },
            -- ["async-recursion"] = { "async_recursion" },
          },
        },
      },
    },
  },

🤔 that's a bug that was introduced recently. I'll fix it later today.

Just released a fix 😄

@mrcjkb Is it possible to toggle this option on the fly?

I've tried this:

      local function toggle_check_on_save()
        local old_val = vim.g.rustaceanvim.server.default_settings["rust-analyzer"].checkOnSave
        vim.g.rustaceanvim.server.default_settings["rust-analyzer"].checkOnSave = not old_val

        local status = old_val and "diabled" or "enabled"
        vim.notify("checkOnSave " .. status, vim.log.levels.INFO)
      end
      vim.keymap.set("n", "<leader>ts", toggle_check_on_save, { desc = "Toggle Check on Save" })

But the value never changed. I guess it's readonly.
