sttr.nvim

A Neovim plugin for sttr: select text, pick a transformation, done.

Supports charwise (v), linewise (V), and block (<C-v>) visual selections. The list of available transformations is read dynamically from your installed version of sttr.

Requirements

• Neovim 0.10+
• sttr installed and available in $PATH

Installation

lazy.nvim

{
  'anotherhadi/sttr.nvim',
  config = function()
    require('sttr').setup()
  end,
}

Setup

require('sttr').setup()

No keymaps are set by default. Add your own:

vim.keymap.set('v', '<leader>st', ':<C-u>SttrTransform<CR>', { silent = true, desc = 'sttr: transform selection' })

Commands

Command	Description
:SttrTransform	Open the transformation picker for the current visual selection
:SttrClearCache	Clear the cached transformation list (re-reads sttr --help)

Pickers

The plugin automatically uses the best available picker:

1. telescope.nvim
2. snacks.nvim picker
3. vim.ui.select (built-in, or overridden by snacks/dressing/etc.)

Block visual

In block visual mode (<C-v>), each line of the selection is transformed independently. This is useful for transforming a column of values (e.g. base64-decoding a column of tokens).

Transformations

sttr.nvim dynamically reads transformations from sttr --help at first use, so it always reflects your installed version. sttr supports 60+ operations including:

• Encoding: base64, base32, URL, HTML, hex, morse…
• Hashing: md5, sha256, sha512, bcrypt…
• Case: camelCase, snake_case, kebab-case, UPPER, lower…
• Lines: sort, reverse, unique, shuffle…
• Formats: JSON↔YAML, markdown→HTML…
• Extraction: emails, IPs, URLs…
