How to hide the line number in the left margin?

While taking a new markdown note, the left margin width takes 5 pixels, too wide to be unpleasant.
How to hide the line number? but keep the fold function.
view.margins = 2 does not work.

Try `view.margin_width_n[1] = 0`. The line number margin is first, followed by the marker margin (bookmarks and such), and then the fold margin. The last two margins are hidden (they already have a default width of 0). https://orbitalquark.github.io/textadept/api.html#view.margin_width_n

Thks but view.margin_width_n[1] = 0 not work in TA 12.0 alpha

Oh, sorry about that. If you want this to be a more permanent setting (vs. using the command entry), you'll have to set it in a function connected to `events.BUFFER_NEW` and `events.VIEW_NEW` in your *~/.textadept/init.lua*: local function hide_line_numbers() view.margin_width_n[1] = 0 end events.connect(events.BUFFER_NEW, hide_line_numbers) events.connect(events.VIEW_NEW, hide_line_numbers) Textadept's own *init.lua* does the same, so you need to override it: https://github.com/orbitalquark/textadept/blob/3bc82b2eca020c97abbee2fd3edf6f24f56c864e/init.lua#L162-L168

local function toogle_line_number()
    if view.margin_width_n[1] > 0 then
        view.margin_width_n[1] = 0
    else
        view.margin_width_n[1] = math.max(4, #tostring(buffer.line_count)) * view:text_width(view.STYLE_LINENUMBER, '9') + (not CURSES and 4 or 0)
    end
end
