Merge text2.love
bugfix: cursor _can_ get go out of viewport
Merge text2.love
Proportional font support, word-wrap, scrolling, clipboard integration.
Reliable; tested with Moby Dick.
Easy to understand. 1200 lines of code excluding comments.
Install LÖVE. It's just a 5MB download, open-source and extremely well-behaved.
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/view2.love *.lua
By default, view2.love reads/writes the file lines.txt
in
a directory relative to this app.
To open a different file, drop it on the view2.love window.
While editing text:
ctrl+f
to find patterns within a filectrl+c
to copyctrl+=
to zoom in, ctrl+-
to zoom out, ctrl+0
to reset zoomctrl+a
to select allExclusively 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
No support yet for Unicode graphemes spanning multiple codepoints.
No support yet for right-to-left languages.
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.
Can't scroll while selecting text with mouse.
No scrollbars yet. That stuff is hard.
The editor is entirely within edit.lua, which should be easy to include in other LÖVE projects. It depends on one external (but included) library: json.lua.
Initialization and preflight check:
edit.load()
-- one-time initializationedit.is_this_love_version_supported()
edit.preferred_love_version()
Create empty editor within given borders:
editor = edit.new_from_defaults(top, left, right, bottom)
Load files:
edit.load_file(editor, filename)
Remember editor settings across restart:
edit.new_from_settings(settings, top, left, right, bottom)
-- caller first loads settings first from some filesettings = edit.settings(editor)
-- caller writes settings to some filePlaces to wire into your LÖVE app:
edit.draw(editor)
edit.update(editor, dt)
edit.key_press(editor, key, scancode, isrepeat)
edit.text_input(editor, t)
edit.key_release(editor, key, scancode)
edit.mouse_press(editor, x,y, mouse_button)
edit.mouse_release(editor, x,y, mouse_button)
edit.mouse_wheel_move(editor, dx,dy)
edit.resize(editor, width, height, right, bottom)
edit.focus(editor, in_focus)
Optional helpers:
edit.update_font_settings(editor, font_height)
-- automatically called by keyboard shortcuts by defaultedit.absolutize(filename)
-- included for convenienceThis repo is a fork of lines.love. Its immediate upstream is text2.love, an embeddable text editor widget which provides features like word-wrap, unlimited undo in 1200 lines of code. Updates to it can be downloaded from the following mirrors:

Most appreciated. Messages, PRs, patches, forks, it's all good.
