px86 / linereader

C++ library providing line-editing and history capabilities for interactive command line programs.

Hello, I’m Pushkar Raj

I’m a young programmer from India.

Some of my projects:

• linereader : C++ library providing line editing and history capabilities to interactive CLI programs
• hush : a UNIX shell supporting IO re-directions, piping, background execution etc.
• dff : recursively finds and lists duplicate files
• nights-watch : watches file(s) for modifications and re-executes a given command
• png-steganography-tool : hides information inside PNG images
• pxurl : a URL shortening webapp built using Nodejs, Express and MongoDB Atlas
• clurl : same as pxurl, but written in Common Lisp, and uses PostgreSQL database
• codebin : a hastebin clone for sharing code snippets (with syntax highlighting)
• fisherman, fisherman-backend : a phishing tool (CLI script + backend code)
• album-splitter : splits an album(audio file) into multiple tracks
• css-minifier : minifies CSS for deployment
• bmee : Basic mathematical expressions evaluator

linereader's Issues

Bug: Pressing `ctrl + shift + v` hangs the program

Pressing ctrl + shift + v causes the program to hang and start behaving in a weird way. The CPU usage also spikes up.

Pressing ENTER on empty line does not provide any feedback.

Pressing enter on an empty line, redraws the prompt on the same row and it seems as if nothing has happened.

BUG: history navigation does not work properly

TODO: test on multiple terminal emulators

Currently, I have only tested it on xterm.

BUG: ALT + b moves incorrectly

Before

one two three
          ^

After

one two three
       ^

Ideally

one two three
        ^

TODO: implement kill-ring

Implement Emacs style killing and yanking text.

• C-k to kill from cursor to the end of line
• C-u to kill from cursor to the beginning of the line
• C-y to yank (paste) the content from the kill ring

and so on.

TODO: implement Ctrl + d correctly

Pressing Ctrl + d at the beginning of the line should indicate that EOF has been reached.

Bug: unintended behavior of ALT + b

Cursor position before pressing ALT + b

This is a bug
^

Cursor position after pressing ALT + b

This is a bug
         ^

Ideally, it should not do anything.
