# 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](https://love2d.org). 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](https://love2d.org/wiki/Getting_Started#Running_Games),
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.
## 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.
