Neovim常用配置(2)

Posted on Edited on In

使用 Lua 配置 Neovim，并设置自己的 workflow

结合命令行工具

我在编码时常常有使用 git 的需求，但又不想总是在命令行中敲命令

于是我利用与 ToggleTerm 把命令行工具 lazygit 嵌入至 Neovim 中

local Terminal = require('toggleterm.terminal').Terminal

local lazygit = Terminal:new({ cmd = "lazygit", direction = 'float', hidden = true })
local top = Terminal:new({ cmd = "top", direction = 'float', hidden = true })


-- lazygit
vim.api.nvim_create_user_command("LazyGit",
    function()
        lazygit:toggle()
    end,
    { nargs = 0 })

-- top
vim.api.nvim_create_user_command("Top",
    function()
        top:toggle()
    end,
    { nargs = 0 })

同样类似的，还可以通过命令行工具 trans 进行翻译，并通过 neovim 的 api 将翻译结果显示出来.

local function translate_terminal()
    local mode = vim.api.nvim_get_mode()['mode']
    local to_translate
    if mode == 'n' then
        to_translate = vim.fn.expand('<cword>')
    elseif mode == 'v' then
        to_translate = require('basic').get_visual_selection()
    end
    local command = string.format('trans "%s"', to_translate)

    async.run(function()
        local translated_content = vim.fn.systemlist(command)
        utils.show_term_content(translated_content)
    end)
end

vim.api.nvim_create_user_command(
    "BufferDelete",
    function()
        ---@diagnostic disable-next-line: missing-parameter
        local file_exists = vim.fn.filereadable(vim.fn.expand("%p"))
        local modified = vim.api.nvim_buf_get_option(0, "modified")

        if file_exists == 0 and modified then
            local user_choice = vim.fn.input(
                    "The file is not saved, whether to force delete? Press enter or input [y/n]:")
            if user_choice == "y" or string.len(user_choice) == 0 then
                vim.cmd("bd!")
            end
            return
        end

        local force = not vim.bo.buflisted or vim.bo.buftype == "nofile"

        vim.cmd(force and "bd!" or string.format("bp | bd! %s", vim.api.nvim_get_current_buf()))
    end,
    { desc = "Delete the current Buffer while maintaining the window layout" })
