README.md

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 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.

  • 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.

  • lines.love assumes a file always contains at least one line of text. You can violate this invariant by editing the file outside lines.love. Don't do that.

  • If you make the first line a drawing there's currently no way to insert lines above it.

  • Help screen may show up in multiple drawings at a time. That feels a bit klunky.

  • Clicking on a drawing to focus cursor on it adds a point. Orphaned points disappears on reload, but still. Klunky. To avoid this you can move the cursor using the keyboard, but who can remember that?

  • 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.
