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.

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 file
ctrl+c to copy, ctrl+x to cut, ctrl+v to paste
ctrl+z to undo, ctrl+y to redo
ctrl+= to zoom in, ctrl+- to zoom out, ctrl+0 to reset zoom
alt+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.
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.

Mirrors and Forks

Updates to lines.love can be downloaded from the following mirrors in addition to the website above:

Forks of lines.love are encouraged. If you show me your fork, I'll link to it here.

https://github.com/akkartik/lines-polygon-experiment -- an experiment that uses separate shortcuts for regular polygons. ctrl+3 for triangles, ctrl+4 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.
https://git.sr.ht/~akkartik/lines2.love -- an entirely new implementation of some foundations that seems more elegant.

Associated tools

https://codeberg.org/akkartik/lines2md exports lines.love files to Markdown and (non-editable) SVG.
https://git.sr.ht/~akkartik/lines2html.love exports lines.love files to html and inline SVG.
https://codeberg.org/eril/lines2html.love provides the option to export just the drawings to a directory. Also provides a CLI, which should be more natural for many people.

Feedback

Most appreciated. Messages, PRs, patches, forks, it's all good.
