# A read-only viewer for plain text.

Not very useful by itself, but it's a fork of [lines.love](http://akkartik.name/lines.html)
that you can take in other directions, while easily sharing patches between
forks.

Designed above all to be easy to modify and give you early warning if your
modifications break something.

## Invocation

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/view.love *.lua
```

By default, it 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 app 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
* `ctrl+e` to modify the sources

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.

* 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.

* Can't scroll while selecting text with mouse.

* No scrollbars yet. That stuff is hard.

* There are some temporary limitations when editing sources:
    - no line drawings
    - no selecting text
