vai
to select current context!
Context-aware smart indent object to select block, powered by treesitter.
This plugin is intended to be used with indent-blankline.nvim, so you see the scope before you select.
NOTE: This plugin is only compatible with indent-blankline.nvim v2 because its definition of scope has been changed on v3. My personal preference is to keep using v2 as its scope aligns well with VSCode.
Use your favourite plugin manager to install.
This includes lazy-loading on keymaps. If you install like this, you can ignore every instruction below.

setup()
is not required, but here is the recommendation.
require("indent_blankline").setup {
show_current_context = true,
show_current_context_start = true,
}
-- Actually, no setup is required, but
-- if setup comes after the indent_blankline,
-- it will try to follow the pattern matching options
-- used in indent_blankline
require("treesitter_indent_object").setup()

Lua equivalent:
-- select context-aware indent
vim.keymap.set({"x", "o"}, "ai", function() require'treesitter_indent_object.textobj'.select_indent_outer() end)
-- ensure selecting entire line (or just use Vai)
vim.keymap.set({"x", "o"}, "aI", function() require'treesitter_indent_object.textobj'.select_indent_outer(true) end)
-- select inner block (only if block, only else block, etc.)
vim.keymap.set({"x", "o"}, "ii", function() require'treesitter_indent_object.textobj'.select_indent_inner() end)
-- select entire inner range (including if, else, etc.) in line-wise visual mode
