# Introduction



Neovim harpoon plugin, but only the core bits.



Many thanks to [ThePrimeagen](https://github.com/ThePrimeagen), this

implementation takes many ideas from the original

[harpoon](https://github.com/ThePrimeagen/harpoon) plugin, as well as

various naming conventions for the commonly used publically exposed methods.



The idea is I like all the file marking and switch logic that's part of `harpoon`,

but am not interested in all of the TMUX / terminal stuff.



Looks like `ThePrimeagen` expresses some similar thoughts based on:

[issue-255](https://github.com/ThePrimeagen/harpoon/issues/255).



There are pretty large changes in this implementation so mapping the 2 outside

of what is available publically is not straightforward.



# Features



- Supports running multiple different projects at the same time without losing any

  changes to your marked files.

- Invalid marks get filtered out, only valid changes propagate to marks.

- Marking files at a branch granularity if `mark_branch` option is set.

- Will set active window to specified file if it is already open rather than

  opening another window if `use_existing` option is set, works across tabs.

- Supports storing and using last cursor position if `use_cursor` option is set.

- Supports different default actions when opening a mark with `default_action` option.

- A migration script to move existing harpoon marks over.



# Limitations



- Having the same project open in multiple instances of Neovim will cause

  changes to your marked files to get clobbered.



# Differences from Original



While many of the publically exposed behaviors have been copied to be nearly exact

there are a couple of intentional differences in behavior:



- Invalid files are never saved to your marks. When editing you can add whatever

  lines you want to the preview, but if it doesn't point to an actual file it'll

  be thrown out immediately and never persisted. This will also happen if you later

  delete a file after the first time you open the preview window.

- As a consequence of the above empty lines are also not allowed. Though there may

  be some value in having your shortcuts remain consistent even when some file is

  removed this implementation avoids having placeholder slots that need special handling.

- Minor other changes and bug fixes such as [218](https://github.com/ThePrimeagen/harpoon/pull/218).



# Install



## lazy.nvim



```lua

{

    'MeanderingProgrammer/harpoon-core.nvim',

    config = function()

        require('harpoon-core').setup({})

    end,

}

```



# Setup



Below is the configuration that gets used by default, any part of it can be modified

by the user.



```lua

require('harpoon-core').setup({

    -- Make existing window active rather than creating a new window

    use_existing = true,

    -- Default action when opening a mark, defaults to current window

    -- Example: 'vs' will open in new vertical split, 'tabnew' will open in new tab

    default_action = nil,

    -- Set marks specific to each git branch inside git repository

    mark_branch = false,

    -- Use the previous cursor position of marked files when opened

    use_cursor = true,

    -- Settings for popup window

    menu = { width = 60, height = 10 },

    -- Controls confirmation when deleting mark in telescope

    delete_confirmation = true,

})

```



# Migrate Harpoon Marks



This can be done by executing the import_harpoon script: `python3 scripts/import_harpoon.py`



This requires `python` to be installed but does not rely on any additional libraries.



# Harpooning



This section is a copy paste from the original, with some minor changes / additions.



You can see an example config which assigns all of these commands to keymaps

[here](https://github.com/MeanderingProgrammer/dotfiles/blob/main/.config/nvim/lua/plugins/harpooncore.lua).



Here we'll explain how to wield the power of the harpoon.



## Marks



### Adding



You mark files you want to revisit later on.



```lua

:lua require('harpoon-core.mark').add_file()

```



### Removing



These can also be removed.



```lua

:lua require('harpoon-core.mark').rm_file()

```



## File Navigation



View all project marks.



```lua

:lua require('harpoon-core.ui').toggle_quick_menu()

```



You can go up and down the list, enter, delete or reorder. `q` and `` exit

and save the menu.



You can also switch to any mark without bringing up the menu. Below example uses

3 as the target file.



```lua

:lua require('harpoon-core.ui').nav_file(3)

```



You can also cycle the list in both directions.



```lua

:lua require('harpoon-core.ui').nav_next()

:lua require('harpoon-core.ui').nav_prev()

```



From the quickmenu, open a file in:



- Vertical split with ``

- Horizontal split with ``

- New tab with ``



# Telescope Support



First register harpoon as a telescope extension.



```lua

require('telescope').load_extension('harpoon-core')

```



Then open the marks page.



```lua

Telescope harpoon-core marks

```



Valid keymaps in Telescope are:



- `` delete the current mark

- `` move mark up one position

- `` move mark down one position
