I'm not sure this is very useful. I had an initial idea to stop using screen_bottom1 in final_text_loc_on_screen, by starting from screen_top1 rather than screen_bottom1. But that changes the direction in which we scan for the text line in situations where there is somehow no text on screen (something that should never happen but I have zero confidence in that). Still, it doesn't seem like a bad thing to drastically reduce the lifetime of some derived state. Really what I need to do is throw this whole UX out and allow the cursor to be on a drawing as a whole. So up arrow or left arrow below a drawing would focus the whole drawing in a red border, and another up arrow and left arrow would skip the drawing and continue upward. I think that change to the UX will eliminate a whole class of special cases in the code. |

Plain text with lines
An editor for plain text where you can also seamlessly insert line drawings. Designed above all to be easy to modify and give you early warning if your modifications break something.
http://akkartik.name/lines.html
Getting started
Install LÖVE. It's just a 5MB download, open-source and
extremely well-behaved. I'll assume below that you can invoke it using the
love
command, but that might vary depending on your OS.
To run from the terminal, pass this directory to LÖVE, optionally with a file path to edit.
Alternatively, turn it into a .love file you can double-click on:
$ zip -r /tmp/lines.love *.lua
By default, lines.love reads/writes the file lines.txt
in
a directory relative to this app.
To open a different file, drop it on the lines.love window.
Keyboard shortcuts
While editing text:
ctrl+f
to find patterns within a filectrl+c
to copy,ctrl+x
to cut,ctrl+v
to pastectrl+z
to undo,ctrl+y
to redoctrl+=
to zoom in,ctrl+-
to zoom out,ctrl+0
to reset zoomalt+right
/alt+left
to jump to the next/previous word, respectively- mouse drag or
shift
+ movement to select text,ctrl+a
to select all ctrl+e
to modify the sources
For shortcuts while editing drawings, consult the online help. Either:
- hover on a drawing and hit
ctrl+h
, or - click on a drawing to start a stroke and then press and hold
h
to see your options at any point during a stroke.
lines.love has been exclusively tested so far with a US keyboard layout. If you use a different layout, please let me know if things worked, or if you found anything amiss: http://akkartik.name/contact
Known issues
-
No support yet for Unicode graphemes spanning multiple codepoints.
-
No support yet for right-to-left languages.
-
Undo/redo may be sluggish in large files. Large files may grow sluggish in other ways. lines.love works well in all circumstances with files under 50KB.
-
If you kill the process, say by force-quitting because things things get sluggish, you can lose data.
-
The text cursor will always stay on the screen. This can have some strange implications:
- A long series of drawings will get silently skipped when you hit page-down, until a line of text can be showed on screen.
- If there's no line of text at the top of the file, you may not be able to scroll back up to the top with page-up.
So far this app isn't really designed for drawing-heavy files. For now I'm targeting mostly-text files with a few drawings mixed in.
-
No clipping yet for drawings. In particular, circles/squares/rectangles and point labels can overflow a drawing.
-
If you ever see a crash when clicking on the mouse, it might be because a mouse press and release need to happen in separate frames. Try pressing and releasing more slowly and let me know if that helps or not. This is klunky, sorry.
-
Touchpads can drag the mouse pointer using a light touch or a heavy click. On Linux, drags using the light touch get interrupted when a key is pressed. You'll have to press down to drag.
-
Can't scroll while selecting text with mouse.
-
No scrollbars yet. That stuff is hard.

uses separate shortcuts for regular polygons.
ctrl+3

for squares, etc. - https://git.sr.ht/~akkartik/text.love -- a stripped down version without drawings; useful starting point for some forks
- https://git.sr.ht/~akkartik/pensieve.love -- a note-taking app on an infinite 2D surface. Still in development.
- https://git.sr.ht/~akkartik/capture.love -- a blank-slate mode for the note-taking app, so all the stuff pensieve.love puts on screen doesn't cause you to forget what you came to write down.
