For now, you can use nvim-web-devicons to add file icon.
nvim-web-devicons
and start it.require'nvim-web-devicons'.setup {}
require'nvim-web-devicons'.get_icon(filename, extension, options)
and you should get filename and extension from tabid. Overall, the code will looks like:
local focus_win = vim.api.nvim_tabpage_get_win(tabid)
local filename = require("tabby.filename").tail(focus_win)
local extension = local fname = vim.fn.fnamemodify(name, ':e')
local icon = require'nvim-web-devicons'.get_icon(filename, extension)
A little survey: Is it helpful to add a helper function to get the file icon in tabby.nvim
?
Yeah, will be good.
Even more important is the buf modified sign. What do u thing about this:
local function win_label(winid, top)
local icon = top and '' or ''
local fname = require("tabby.filename").tail(winid)
local extension = vim.fn.fnamemodify(fname, ':e')
local fileIcon = require'nvim-web-devicons'.get_icon(filename, extension)
local buid = vim.api.nvim_win_get_buf(winid)
local is_modified = vim.api.nvim_buf_get_option(buid, 'modified')
local modifiedIcon = is_modified and '' or ''
return string.format(' %s %s %s %s', icon, fileIcon, filename.unique(winid), modifiedIcon)
end
I think this is workable. I plan to improve the configuration experience, use less code to configure these things. I will update in this issue if that is completed.
Let me share my way.
local function buffer_render (bufid, is_current)
local buftype = vim.bo[bufid].buftype
local modified = vim.bo[bufid].modified
local modified_icon = modified and '' or ' '
local path = vim.fn.bufname(bufid);
local extension = vim.fn.fnamemodify(path, ":e")
local filename = vim.fn.fnamemodify(path, ":t")
local fileicon = require'nvim-web-devicons'.get_icon (filename, extension, { default = true})
local buf_name = ' ' .. fileicon .. ' ' .. filename ..' ' .. modified_icon .. ' '
local buf_color = is_current and active_tab_hl or inactive_tab_hl
return {
type = 'text',
text = {
string.format(' %s ', buf_name) ,
hl = buf_color,
}
}
end
local components = function()
local cur_bufid = vim.api.nvim_get_current_buf()
for _, bufid in ipairs(vim.api.nvim_list_bufs()) do
if vim.api.nvim_buf_is_valid(bufid) and vim.bo[bufid].buflisted then
local is_current = false;
if bufid == cur_bufid then
is_current = true
end
local buf_render = buffer_render (bufid,is_current)
table.insert(coms, buf_render)
table.insert(coms,
{
type = 'text',
text = {
' ',
hl = 'TabLineFill'
}
}
)
end
end
--- etc
end
I rewrite the config API in case to easily add helper functions. For example in setup, you can add a file icon by win object:
line.wins_in_tab(line.api.get_current_tab()).foreach(function(win)
return {
line.sep('', theme.win, theme.fill),
win.is_current() and '' or '',
win.file_icon(),
win.buf_name(),
line.sep('', theme.win, theme.fill),
hl = theme.win,
margin = ' ',
}
end),
How can I config to show file icon on tabs.
