exofrills text editor

xo: the text editor without frills

You might be looking for help, but this is all I can do:

usage: xo [-h] path

exofrills: your text has been edited...but you are still hungry.

positional arguments:
  path        path to file, may include colon separated line and col numbers,
              eg 'path/to/xo.py:10:42'

optional arguments:
  -h, --help  show this help message and exit

Someone else made a video tutorial and posted it on YouTube within an hour of the 0.1 release.

get xo

Install from the cheeese shop with pip or easy_install:

$ pip install exofrills

$ easy_install exofrills

Fork xo from github:

$ git clone https://github.com/scopatz/xo.git

key commands

esc:	get help
ctrl + o:	save file (write-out)
ctrl + x:	exit (does not save)
meta + s:	select pygments style
ctrl + f:	insert file at current position
ctrl + y:	go to line & column (yalla, let's bounce)
ctrl + n:	name completion with Jedi (if installed)
ctrl + k:	cuts the current line to the clipboard
ctrl + u:	pastes the clipboard to the current line
ctrl + t:	clears the clipboard (these spell K-U-T)
ctrl + w:	set regular expression and jump to first match
meta + w:	jump to next match of current regular expression
ctrl + r:	set substitution for regular expression and replace first match

xo's Issues

Text show up as white even if background is white.

Forcing the background color is probably the easiest fix.

This is very low priority, as I'm unlikely to actually use exofrills. I may howver steal large parts code for use in an editor/IDE, because I do want more frills. :-)

Python 3.11 - Jedi code is broken / Jedi API changed

Dear mate, the Jedi code has some API changes -- therefore you Jedi code is broken in Cpython 3.11.
Cheers,

Add tags to repo

Hi! Thank you for the useful xontrib!

Please add xonsh and xontrib tags to the repo:

It helps spread the word about xontrib on Github.

Thanks!

The http://exofrills.org/ webpage says 404

The repo https://github.com/scopatz/xo says "exofrills text editor http://exofrills.org/", but http://exofrills.org/ says "The page isn't redirecting properly" in my Firefox.

Using the "down" arror key and when scrolling the column on bottom always displays 1

The steps to reproduce.

1. Open a new terminal and start xo
2. Press the end key to go to end of the line
3. Press the down key until you get to the bottom of the screen
4. Keep pressing the down key and notice the column is stuck on 1

I noticed this bug when fixed #18 I will try and generate a pull request ASAP.

Integrate Jedi's name completion with xo

As @scopatz mentioned in PR #28

1. I would like jedi to be optional, so that if you don't have it, nothing happens.
2. Also it would be good if the jedi import could be lazy so that startup time is still as fast as possible.
3. Please add a news file a la the instructions at https://regro.github.io/rever-docs/news

Files grow by extra newline

To replicate:

• load a file (like xo.py itself)
• save
• quit

The file will have grown an extra newline at the end even if it has a newline at the end. This is probably a bug in the code that is supposed to ensure that a file always ends with a newline.

Disallow installation on python 2.x

This should be forbidden in the setup script - it's very annoying for new users trying the editor and getting a bogus TypeError.

Add multiline string and comment handling

I think I know how to do this....

Takes a long time to start

I did a test, when I open a file, and then close it as quickly as I can using CTRL-X, and measure how long it takes (closing is immediate, the startup time is long):

certik@redhawk:~/repos/xo(master)$ time xx/bin/xo xo.py

real    0m1.442s
user    0m1.036s
sys 0m0.068s

The best time is 1.281s. Compare to Vim:

certik@redhawk:~/repos/xo(master)$ time vim xo.py 

real    0m0.386s
user    0m0.088s
sys 0m0.008s

user    0m0.084s
sys 0m0.008s
certik@redhawk:~/repos/xo(master)$ time vim xo.py 

real    0m0.354s
user    0m0.068s
sys 0m0.012s
certik@redhawk:~/repos/xo(master)$ time vim xo.py 

real    0m0.328s
user    0m0.092s
sys 0m0.004s

Best time 0.282s, and I have to press ZZ, which is slower than CTRL+X.

Conclusion: xo takes 1s more to start than vim on my machine. Vim is immediate (the 0.2s is the time it takes me to pres ZZ), while xo literally takes a second to start.

Missing rc.json

Hello.
Tried to open rc.json right after installing and it wasn't successful:

> xo --rc
Traceback (most recent call last):
  File "/home/delameter/.local/bin/xo", line 1122, in <module>
    main()
  File "/home/delameter/.local/bin/xo", line 1109, in main
    with open(RC_PATH) as f:
FileNotFoundError: [Errno 2] No such file or directory: '/home/delameter/.config/xo/rc.json'

Installed with pip install exofrills (i.e. user installation)

> mkdir /home/delameter/.config/xo
> touch /home/delameter/.config/xo/rc.json
> xo --rc-edit
Warning: rc file not valid JSON.
(empty file)

Maybe something like writing default config if current is empty should be implemeneted?

Using xo xontrib freezes everything

Recently when I've tried using the xo xontrib in xonsh, it has started just freezing - it doesn't load anything, it just sits there on the line after the command to run xo until I hit ctrl+c to try and close out and try again/something else. Event then hitting ctrl+c doesn't always exit the call to xo and I have to restart xonsh.

I'm not entirely sure what may have caused this, though I suspect it may be something related to upgrading xo from 0.1.11 to 0.1.13

Tested using xonsh 5.2 and 5.3, Ubuntu 14.04, python 3.4, xonsh and xo/exofrills installed using pip (for python 3.4).

I also tried unloading the xo xontrib and running the stand-alone xo command and that works just fine.
Only other xontrib loaded in xonsh is apt_tabcomplete which seems to work just fine as well.

not working properly

I tried installing it on my mac with pip3. It successfully finished installing but when tried to run I got dependency errors:

Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
from collections import deque, Mapping, Sequence

and

Traceback (most recent call last):
File "/usr/local/bin/xo", line 34, in
import urwid
ModuleNotFoundError: No module named 'urwid'

and

Traceback (most recent call last):
File "/usr/local/bin/xo", line 36, in
import pygments_cache
ModuleNotFoundError: No module named 'pygments_cache'

The last two I could solve by pip install urwid and pygments_cache. But the first one I don't know how to solve.

add better error handling when no filename is provided

Currently xo on its own will fail with a trace back

Change color scheme

Hi

how can I change xo's color scheme? On the default Ubuntu terminal (black on white background) I cannot see anything in xo. Second question: which is the meta key? Gnome intercepts the "windows" key.

Best

Pressing "end" doesn't update column count in the status bar

When pressing 'end' to jump to the end of a line, the column count in the status bar does not update until the cursor next moves with an arrow key press etc.
'home' key works as expected.

Using xo from pip3

Newlines are stripped while chosing a style

Steps to reproduce

• go to end of file
• press alt-s to chose style
• press backspace

Result:

• New lines are removed from the editor

Expected result:

• Nothing should happen as the style selection input has the focus

Not saving

I've tried this a few ways, both with pypi and github version - saving doesn't seem to happen:

Add Installation Requirements

Installing xo through pip doesn't install any dependencies. Please add them to setup.py.

Ctrl+Right won't jump to the end of a line

But Ctrl+Left to go left 1 word does go left 1 word like it should. Not sure I can fix this but I can try.
