A RSVP in Rust with eframe & egui
Ship #1
Pending review
R(ust)SVP
A realy fast speed reading app built in Rust ! ᕙ( •̀ ᗜ •́ )ᕗ
What did you make ?
I built a Rapid Serial Visual Presentation (RSVP) application from scratch using Rust!
Instead of reading a block of text from left to right, R(ust)SVP flashes words one by one in the exact center of your screen.
This reduce the time your eyes spend moving across the page, letting you read really fast. I built the graphical interface using egui (via the eframe framework).
Here is what’s inside:
-
Custom Speed Control: a slider to adjust your Words Per Minute (WPM)
-
Native File Picker: i added
rfd(Rust File Dialog) so you can open a native window to load your own text files directly into the reader. -
Drag & Drop: you can just drop a
.txtfile and start reading it -
Cross-Platform: can be used on Windows, macOS and Linux !
What was challenging ?
-
UI:
eguiis very simple to create basic UI but when you want to add custom button style, font, its start to be a little bit hard -
String parsing: splitting a text file into a “list” of words, being able to get the comma, dot, punctuation etc… and keeping track of the current index so you can jump around the text
What are you proud of ?
I am proud of successfully building and shipping a complete native GUI application in Rust for the first time ! ദ്ദി(˵ •̀ ᴗ - ˵ ) ✧
What should people know so they can test your project ?
How to test:
- You can just do
cargo install rustsvpand run it withrustsvp!
ദ്ദി(˵ •̀ ᴗ - ˵ ) ✧
Things to try
-
Load up a long text (like a wikipedia article) or a chapter of a book
-
Start the speed at 300 WPM, and slowly crank the slider up to 500+ WPM while reading.
-
Try using the back and forward button to go back and forth through the text if you miss a sentence.
Last devlogs before Ship ! 
I have done the README.md and upload the video + screen shot. All I have to do now is publish it to crates.io / cargo !

I have done a lot of optimization and reorganization in the code so it’s clean as possible
I also added the Drag & Drop feature with error management if the file is not a .txt file
Devlogs number…. 5 
In this devlogs I have added simple things such as :
- Guide line for the center letter of the word

2nd devlogs
Here are the things that I have added:
-

-
The text is center on the screen, and the RED
character never move from the center of the screen, so there is no need to move the eyes -
Text is now bigger

Punctuation are now at the end of the previous word
-
The last word stay in place even when the text is finished (before it was showing nothing)
