How to add Rename button

[rchastain]

I would like, when I save a file as..., to have the choice between Save and Rename (as in Geany). Could someone explain to me how to do?

Textadept does not have this feature. It uses your OS's standard dialog for saving files. You'd have to use a file manager to remove the file manually after saving. If you are open to scripting Textadept, you could implement this feature yourself. It would require adding some code to your ~/.textadept/init.lua. Let me know if you are and I could give you some pointers.

Yes, I am! I would be very glad to learn how to do that.

You can define a function in your ~/.textadept/init.lua:

-- Invoke `buffer:save_as()`, and if the file changes, prompt the user to delete the old file.
local function save_as()
  local filename = buffer.filename
  if not buffer:save_as() then return end -- user did not complete save_as
  if not filename or filename == buffer.filename then return end -- filename did not change
  -- At this point, the filename has changed.
  local button = ui.dialogs.message{
    title = 'Delete File?', text = 'Would you like to delete ' .. filename .. '?',
    icon = 'dialog-question', button1 = 'Keep old file', button2 = 'Delete old file'
  }
  if button == 2 then os.remove(filename) end -- delete the old file
end

Then you can assign your function to Textadept's File > Save As menu and Ctrl+Shift+S key binding:

textadept.menu.menubar['File/Save As'][2] = save_as
keys['ctrl+S'] = save_as

Great! Thank you very much.
