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

Like all LÖVE apps, lines.love can be invoked either from a terminal or by clicking on the application in a graphical desktop.

When invoked from a terminal, you can pass the love binary the path to either the zipped lines.love or a directory containing lines.love unzipped.

$ path/to/love path/to/lines.love

$ path/to/love .  # from this repo directory
$ path/to/love path/to/lines/directory  # from anywhere

By default, lines.love reads/writes the file lines.txt in your default user/home directory (https://love2d.org/wiki/love.filesystem.getUserDirectory).

When invoked from a terminal, you can pass in a different file to edit, either to the zipped or unzipped versions:

$ path/to/love path/to/lines.love path/to/file/to/edit

$ path/to/love path/to/lines/directory /path/to/file/to/edit

On a graphical desktop you can also drag and drop a file icon on to the lines.love window.

You can also configure the size of the window on the commandline. For example:

$ path/to/love path/to/lines.love -geometry 640x480+10+10 path/to/file/to/edit

The syntax of the geometry parameter is {width}x{height}+{x}+{y} which will position the top-left corner of the window at co-ordinate (x,y). The geometry parameter must come before the file to edit.

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

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

  • There's a bug in freehand drawings (C-p mode) that causes them to be highlighted even when the mouse is nowhere near them.

  • No support yet for Unicode graphemes spanning multiple codepoints.

  • Undo/redo can be sluggish in large files. If things get sluggish, killing the process can lose data.

  • Large files may grow sluggish in other ways. Pasting more than a line or two gets slow. I've noticed in 100KB files that closing the window can take a few seconds. And it seems to take longer in proportion to how far down my edits are. The phenomenon persists even if I take out undo history.

  • 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 and point labels can overflow a drawing.

  • Insufficient handling of constraints when moving points. For example, if you draw a manhattan line and then move one of the points, you may not be able to hover on it anymore.

    There's two broad ways to fix this. The first is to relax constraints, switch the manhattan line to not be manhattan. The second is to try to maintain constraints. Either constrain the point to only move along one line (but what if it's connected to two manhattan lines?!), or constrain the other end of the line to move alongside. I'm not sure yet which would be more useful. Getting into constraints would also make the program more complex.

    Bottomline: at the moment moving points connected to manhattan lines, rectangles or squares can break drawings in subtle ways.

  • 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.
