Help you get in the flow with ripgrep in Neovim

rgflow.nvim

Get in the flow with RipGrep. The more you use this plugin, the better you become at using RipGrep from the CLI. Not simply a wrapper which could be replaced by a few lines of config. It's a very simple to use tool aspiring to the Unix philosophy.

QuickStart Guide (TL;DR)

1. Ensure you have RipGrep installed
2. Set your plugin manager to use mangelozzi/nvim-rgflow.lua and install the plugin.
3. Create a file for the configuration, e.g. ~/.config/nvim/after/plugin/rgflow.lua
4. Paste in the minimal configuration code:

require('rgflow').setup(
    {
        -- Set the default rip grep flags and options for when running a search via
        -- RgFlow. Once changed via the UI, the previous search flags are used for 
        -- each subsequent search (until Neovim restarts).
        cmd_flags = "--smart-case --fixed-strings --ignore --max-columns 200",

        -- Mappings to trigger RgFlow functions
        default_trigger_mappings = true,
        -- These mappings are only active when the RgFlow UI (panel) is open
        default_ui_mappings = true,
        -- QuickFix window only mapping
        default_quickfix_mappings = true,
    }
)

5. After restarting Neovim, press <leader>rg to open the RgFlow UI
6. Type in a search pattern and press <ENTER>
7. A search will run and populate the QuickFix window
8. Press dd to delete a QuickFix entry, or select a visual range and press d
9. Press TAB to mark a line and <S-TAB> to unmark a line, a line can be marked more than once

If you like this plugin please give it a ⭐! If you don't, you should try Windows.

Bonus note: Pressing <TAB> when the UI panel is open provides autocomplete for the line you are on (rip grep flags/cwords/filepaths)

Why

• Main purpose: Perform a RipGrep with interface that is very close to the CLI, yet intuitive, and place those results in the QuickFix list

  • The more you use this plugin, the better you should become at using RipGrep from the CLI.

• Additional features:

  • QuickFix:
    • Delete results operator, e.g. dd, or 3dj and friends
    • Mark/unmark results operator, e.g. <TAB> to mark a result (can be marked more than once), and <S-TAB> to unmark a result.
    • The operators also have a visual range counter variants.
  • RipGrep flags/options auto complete.
  • Bring up RipGrep help in a buffer, so you can navigate/search it Vim style.
  • Find search results asynchronously
  • Populates the QuickFix windows in batches so it seems like it's none blocking.
  • Highlights the search term, so even if :noh the search terms are still highlighted
    • Even if used a regex as the search term
  • You can set it's theme colours. However if you are someone you likes to change color scheme a lot, if you use the defaults they will update to some sane defaults based on the applied scheme.
  • Searches are appended to your command history, so you can easily repeat previous searches
    • E.g. :<up>

• I can never remember include/exclude globs, this helps.

  • Also has autocomplete for RipGrep flags/options with descriptions

• Tested on Linux and Windows

Installation

Use your favourite plugin manager, e.g. with Packer:

use("mangelozzi/nvim-rgflow.lua")

And then :PackerSync etc. to install it.

Setup

• For a minimal config refer to the Quick start guide.

cmd_flags

• The parameter of most interest is probably cmd_flags
  • The default value is cmd_flags = "--smart-case --fixed-strings --no-fixed-strings --no-ignore --ignore --max-columns 500"
  • The reason it contains opposing settings (e.g. --no-ignore vs --ignore), is because then one can quickly deletes options as required
  • E.g. since the later option "wins", deleting --ignore will make the --no-ignore flag take effect

Mappings

• By default RgFlow will not change your editors current behaviour or modify any mappings.
  • You have to opt in to use the default mappings

Default Mappings

    mappings = {
        trigger = {
            -- Normal mode maps
            n = {
                ["<leader>rG"] = "open_blank", -- open UI - search pattern = blank
                ["<leader>rg"] = "open_cword", -- open UI - search pattern = <cword>
                ["<leader>rp"] = "open_paste", -- open UI - search pattern = First line of unnamed register as the search pattern
                ["<leader>ra"] = "open_again", -- open UI - search pattern = Previous search pattern
                ["<leader>rx"] = "abort",      -- close UI / abort searching / abortadding results
                ["<leader>rc"] = "print_cmd",  -- Print a version of last run rip grep that can be pasted into a shell
                ["<leader>r?"] = "print_status",  -- Print info about the current state of rgflow (mostly useful for deving on rgflow) 
            },
            -- Visual/select mode maps
            x = {
                ["<leader>rg"] = "open_visual", -- open UI - search pattern = current visual selection
            },
        },
        -- Mappings that are local only to the RgFlow UI
        ui = {
            -- Normal mode maps
            n = {
                ["<CR>"]  = "start", -- With the ui open, start a search with the current parameters
                ["<ESC>"] = "close", -- With the ui open, discard and close the UI window
                ["?"]     = "show_rg_help", -- Show the rg help in a floating window, which can be closed with q or <ESC> or the usual <C-W><C-C>
                ["<BS>"]  = "nop",   -- No operation
                ["<C-^>"] = "nop",   -- No operation
                ["<C-6>"] = "nop",   -- No operation
            },
            -- Insert mode maps i = {
                ["<CR>"]  = "start", -- With the ui open, start a search with the current parameters (from insert mode)
                ["<TAB>"] = "auto_complete", -- start autocomplete if PUM not visible, if visible use own hotkeys to select an option
                ["<C-N>"] = "auto_complete", -- start autocomplete if PUM not visible, if visible use own hotkeys to select an option
                ["<C-P>"] = "auto_complete", -- start autocomplete if PUM not visible, if visible use own hotkeys to select an option
            },
        },
        -- Mapping that are local only to the QuickFix window
        quickfix = {
            -- Normal
            n = {
                ["d"] = "qf_delete",        -- QuickFix normal mode delete operator
                ["dd"] = "qf_delete_line",  -- QuickFix delete a line from quickfix
                ["<TAB>"] = "qf_mark",      -- QuickFix mark a line in the quickfix
                ["<S-TAB>"] = "qf_unmark",  -- QuickFix unmark a line in the quickfix window
                ["<BS>"]  = "nop", -- No operation
                ["<C-^>"] = "nop", -- No operation - Probably don't want to switch to a buffer in the little quickfix window
                ["<C-6>"] = "nop", -- No operation
            },
            -- Visual/select mode maps
            x = {
                ["d"] = "qf_delete_visual",       -- QuickFix visual mode delete operator
                ["<TAB>"] = "qf_mark_visual",     -- QuickFix visual mode mark operator
                ["<S-TAB>"] = "qf_unmark_visual", -- QuickFix visual mode unmark operator

        },
    }

Full configuration options

For the full list of configurable settings refer to Default settings

Example Config

This is my personnel configuration:

require("rgflow").setup(
    {
        default_trigger_mappings = true,
        default_ui_mappings = true,
        default_quickfix_mappings = true,

        -- WARNING !!! Glob for '-g *{*}' will not use .gitignore file: https://github.com/BurntSushi/ripgrep/issues/2252
        cmd_flags = ("--smart-case -g *.{*,py} -g !*.{min.js,pyc} --fixed-strings --no-fixed-strings --no-ignore -M 500"
            -- Exclude globs
            .. " -g !**/.angular/"
            .. " -g !**/node_modules/"
            .. " -g !**/static/*/jsapp/"
            .. " -g !**/static/*/wcapp/"
        )
    }
)

Lua Commands

• If you wish to create your own mappings, the below functions are provided.
• None of these commands require args except setup and search, however open can take optional args.

Bonus Tips

• This plugin compliments :Cfilter very well.
  • :Cfilter is built into Vim/Neovim for filtering your QuickFix lists.
  • Although it comes with Neovim, it must first be enabled with: vim.cmd('packadd cfilter')
  • :Cfilter foo will limit your QuickFix results to only those that contain the phrase foo
  • :Cfilter! foo does the inverse, only those that don't contain foo are kept.
• By using Cfilter and this plugin's delete function, you can quickly message your QuickFix list, making it ready to unleash a :cdo and :cfdo ... unlocking all sorts of super powers.
  • e.g. To substitute the word foo for bar on each QuickFix match then save the modified file:
    • :cdo s/foo/bar/ | update
