Editor Jump to End

[rob7cc]

Is there a method or a setting to always start at the bottom of a file that is opened in the editor? Or, equivalently, remember the cursor position in the editor on a per-file basis? I understand I can long-press the scrollbar on the right and drag to the bottom fairly quickly, but I was wondering if there is anything even quicker. I could use keyboard shortcuts (e.g. ctrl+down) but I’m not using an external keyboard. I looked through the documentation for the editor package to see if there was a “jump_to” method or something similar, but no dice. Thank you!

Something like this should jump to the bottom, but there is currently no way to trigger a script when a file is opened.

import editor
editor.set_selection(len(editor.get_text()))

Slick! Thank you!

You could define automatically at Pythonista start an additional button, for instance ⏬ at left of the "run" button (right arrow triangle) and tapping this button, when you are in edit mode of a file, would execute the two lines script of @omz

This code is based on an initial script of @jsbain , obviously one of the Pythonista's gurus

create pythonista_startup.py in Python Modules/site-packages (user) with

import appex
if not appex.is_running_extension():
   try:
    import My_End_Button_in_TitleBar	 # end button in titlebar
  except Exception as e:
    pass

and create My_End_Button_in_TitleBar.py in same directory with

from objc_util import *
import os,ui,console
import weakref
from functools import partial

w=ObjCClass('UIApplication').sharedApplication().keyWindow()
main_view=w.rootViewController().view()

def get_toolbar(view):
	#get main editor toolbar, by recursively walking the view
	sv=view.subviews()
	for v in sv:
		if v._get_objc_classname().startswith(b'OMTabViewToolbar'):
			return v
		tb= get_toolbar(v)
		if tb:
			return tb
def create_toolbar_button(action,index=0):
	assert(callable(action))
	tb=get_toolbar(main_view)
	global __persistent_views
	try:
		__persistent_views
	except NameError:
		__persistent_views={}
	#check for existing button in this index and delete if needed
	remove_toolbar_button(index)	
	btn = ui.Button()
	#btn.frame = (tb.size().width - tb.rightItemsWidth()-(index+1)*40,22,40,40)
	btn.frame = (tb.size().width - 210,22,40,40)
	btn.flex='L'
	btn.title = "⏬"
	btn.action=action
	btn_obj=ObjCInstance(btn)
	__persistent_views[index]=(btn,action)
	on_main_thread(tb.superview().superview().addSubview_)(btn_obj) # in front of all buttons
	return btn
def remove_toolbar_button(index):
	global __persistent_views
	try:
		btn,action = __persistent_views.pop(index)
		btn.action= None
		on_main_thread(ObjCInstance(btn).removeFromSuperview)()
	except KeyError:
		pass

if 1==1:#__name__=='__main__': # if imported by pythonista startup
	def my_wrench(sender):
		import editor
		editor.set_selection(len(editor.get_text()))
		
	create_toolbar_button(my_wrench, 0)

Thank you! This approach is clever. It does render the ⏬️ button but it seems to jump to the top rather than the bottom. With this and @omz post, I have good solutions. Thank you!

Normally, it jumps to the bottom but you only see that if you are in edit mode (keyboard, thus cursor, visible).

the @omz code is included in the ⏬️ button action
