โ Originally this was written for only markdown code blocks. However this plugin now support any language injection in any language!
Catalyze your Fenced Markdown Code-block editing!
(based on this)
A small plugin allowing to edit injected language trees with correct filetype in a floating window. This allows you to use all of your config for your favorite language. The buffer will be also linked to a temporary file in order to allow LSPs to work properly.
Powered by treesitter, lua and coffee.
femaco.mp4
For example using packer:
use {
'AckslD/nvim-FeMaco.lua',
config = 'require("femaco").setup()',
}Requires nvim-treesitter.
Pass a dictionary into require("femaco").setup() with callback functions.
These are the defaults:
require('femaco').setup({
-- should prepare a new buffer and return the winid
-- by default opens a floating window
-- provide a different callback to change this behaviour
-- @param opts: the return value from float_opts
prepare_buffer = function(opts)
local buf = vim.api.nvim_create_buf(false, false)
return vim.api.nvim_open_win(buf, true, opts)
end,
-- should return options passed to nvim_open_win
-- @param code_block: data about the code-block with the keys
-- * range
-- * lines
-- * lang
float_opts = function(code_block)
return {
relative = 'cursor',
width = clip_val(5, 120, vim.api.nvim_win_get_width(0) - 10), -- TODO how to offset sign column etc?
height = clip_val(5, #code_block.lines, vim.api.nvim_win_get_height(0) - 6),
anchor = 'NW',
row = 0,
col = 0,
style = 'minimal',
border = 'rounded',
zindex = 1,
}
end,
-- return filetype to use for a given lang
-- lang can be nil
ft_from_lang = function(lang)
return lang
end,
-- what to do after opening the float
post_open_float = function(winnr)
vim.wo.signcolumn = 'no'
end
-- create the path to a temporary file
create_tmp_filepath = function(filetype)
return os.tmpname()
end,
-- if a newline should always be used, useful for multiline injections
-- which separators needs to be on separate lines such as markdown, neorg etc
-- @param base_filetype: The filetype which FeMaco is called from, not the
-- filetype of the injected language (this is the current buffer so you can
-- get it from vim.bo.filetyp).
ensure_newline = function(base_filetype)
return false
end,
-- Return true if the indentation should be normalized. Useful when the
-- injected language inherits indentation from the construction scope (e.g. an
-- inline multiline sql string). If true, the leading indentation is detected,
-- stripped, and restored before/after editing.
--
-- @param base_filetype: The filetype which FeMaco is called from, not the
-- filetype of the injected language (this is the current buffer, so you can
-- get it from vim.bo.filetype).
normalize_indent = function (base_filetype)
return false
end
})Call :FeMaco or require('femaco.edit').edit_code_block() with your cursor on a code-block. Edit the content, then save and/or close the popup to update the original buffer.
Thanks to everyone working on neovim core, lua-api, treesitter etc which have made plugins like these a joy to create!
