question: trim_whitespace when no formatter and no LSP

[0xDmtri]

Hi, heres my current config:

-- Setup Conform formatter
require("conform").setup({
    formatters_by_ft = {
        -- Set specific formatters per language
        lua = { "stylua" },
        python = { "ruff_format", "ruff_organize_imports" },
        javascript = { "prettier" },
        typescript = { "prettier" },
        solidity = { "forge_fmt" },

        -- Use LSP formatting if no specific formatters configured
        default_format_opts = {
            lsp_format = "fallback",
        },

        -- Trim whitespace if no other formatters configured,
        -- and no LSP formatters found
        ["_"] = { "trim_whitespace" },
    },
    format_on_save = {
        timeout_ms = 500,
    },
})

Can't get my head around how could I set to trigger trim_whitespace only if theres no formatter configured and no LSP formatter is available. So that the priority list works in the following order:

configured formatter -> lsp formatter -> trim_whitespace

Many thanks!

Try setting

["_"] = { "trim_whitespace", lsp_format = "prefer" }

Note: you'll need to be on the most recent master commit
