A simple terminal-based open source Spritz-alike.
This command line filter shows input text as a per-word RSVP (rapid serial visual presentation) aligned on optimal reading points. This kind of input mode allows reading text at a much more rapid pace than usual as the eye can stay fixed on a single place.
cat tea.txt | ./speedread -w 250
# Fullscreen mode — clears the terminal, centers the display
cat tea.txt | ./speedread -w 500 -f
The default of 250 words per minute is very timid, designed so that you get used to this. Be sure to try cranking this up, 500wpm should still be fairly easy to follow even for beginners.
For zsh completion, copy _speedread to a directory on your $fpath and run compinit:
cp _speedread ~/.zsh/completions/ # or wherever your fpath points
echo 'fpath=(~/.zsh/completions $fpath)' >> ~/.zshrc
echo 'autoload -U compinit && compinit' >> ~/.zshrc # if not already set
Or run speedread -h / speedread --help for full usage.
speedread is slightly interactive, with these controls accepted:
- [ - slow down by 10%
- ] - speed up by 10%
- space - pause (and show the last two lines of context)
- b - seek back 10 words
- B - seek back 30 words
- q - quit (shows stats and resume point)
You can connect mutt with speedread by putting a macro like this in your ~/.muttrc (or pressing ':' in running mutt and pasting it):
macro pager R "<enter-command>set pipe_decode=yes<enter>v|grep -v '^>' | ~/speedread/speedread<enter><enter-command>unset pipe_decode<enter>q" "speedread"
Then, just press R when viewing a message. Unfortunately, it does not work with non-ASCII messages (probably due to mutt limitations).
Better word timing— done: function words like "not", "can", "but" get extra timeSupport for seeking back/forward— done:b/BkeysMore controls— done:qto quit,b/Bto seek backMake timing coefficients configurable— done:--wordtime,--commatime,--fstoptime,--lentime,--firsttime- Automatically adjust wpm on trained content difficulty (look-ahead)?
- Add a (Cairo-based?) simplistic graphical frontend (keeping with the filter philosophy). This would allow better eye guidance and large font.
- An elinks-based recipe for reading websites this way.
