A TUI text reader for the terminal.

Fltrdr, or flat-reader, is an interactive text reader for the terminal. It is flat in the sense that the reader is word-based. It creates a horizontal stream of words by ignoring all newline characters and removing sequential whitespace. Its purpose is to facilitate reading, scanning, and searching text. The program has a play mode that moves the reader forward one word at a time, along with a configurable words per minute (WPM) setting. It can be used to read text from either a file or stdin.

This program uses raw terminal control sequences to manipulate the terminal, such as moving the cursor, styling the output text, and clearing the screen. Although some of the control sequences used may not work as intended on all terminals, they should work fine on any modern terminal emulator.
This section describes what environments this program may run on, any prior requirements or dependencies needed, and any third party libraries used.
Any shell commands using relative paths are expected to be executed in the root directory of this repository.
Using a new version of gcc or llvm is required, as the default
Apple llvm compiler does not support C++17 Standard Library features such as
A new compiler can be installed through a third-party package manager such as Brew. Assuming you have Brew already installed, the following commands should install the latest gcc.
brew install gcc
brew link gcc
The following line will then need to be appended to the CMakeLists.txt file.
Replace the placeholder
<path-to-g++> with the canonical path to the new g++ compiler binary.

If you want to permanently use a different base config directory,
~/.config/fltrdr, add the following line to your shell profile:
alias fltrdr="fltrdr --config-base ~/.config/fltrdr"
The following shell commands will create the base config directory in the default location and copy over the example config file:
mkdir -pv ~/.fltrdr
cp -uv ./config/default ~/.fltrdr/config
