Kartik K. Agaram a9aa3436fa bugfix 
Scenario: make some edits, select some text, make some more edits. Press
ctrl-z.

Before this commit, undo would stop at the point of selection and
previous edits would become unreachable.

After this commit, both ctrl-z and ctrl-y seem able to span the point of
selection.

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

Invocation

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 your default user/home directory (https://love2d.org/wiki/love.filesystem.getUserDirectory).

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.

  • 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.

  • Long wrapping lines can't yet distinguish between the cursor at end of one screen line and start of the next, so clicking the mouse to position the cursor can very occasionally do the wrong thing.

  • 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.

  • When editing sources, selecting text is not yet completely implemented.
