Hello,

i wrote a header file, that writes the entered command to the file "$HOME/.psh/history" and it creates the directory if it does not exist. Its pretty simple to use, currently the function call is placed in the main2.c file after the stat = read_cmdline(expanded_ps1, &buffer);.
The function can be called by the name write_to_history(buffer); where buffer is the pointer to the entered command.
It returns an integer, if successfull it returns 0 and if the home directory cannot be found -1.

I included the header file in this comment, im sorry for the format, but Github doesnt accept .h files.
I hope i can help you with this file if you find anything unclear or poorly written dont hesitate to give me feedback, im trying to learn.

history.txt

I have tested the file on an arco Linux machine, and it worked as expected without any warning or error.

After using it the first time you will get a new folder in your home directory containing a history file that holds all entered commands.

Currently i struggle a little bit with doxygen to create a proper documentation for the file.

Please excuse my mistakes, im fairly new to c and to Github.

Looking forward to your reply. :)

Sincerely,
DevManu-de

Dear Manuel, Thanks! You just can’t imagine how excited I was when I saw your message. Your contribution is much appreciated. I will definitely take your code into account when doing this part. I really like your idea of putting everything into a folder, instead of creating a whole crowd of files like what `bash` and `zsh` are doing. However, there are still some issues about history to be resolved. I have to rewrite `builtins/history.c` (#16) before handling saving/loading history. But before that, I think I should finish implementing variables (#8) first. So there’s still lots to do. I’m sorry, but only when those bunch of things is done can I work on this😢. But don’t be sad or discouraged. I am also a beginner. And I remembered my first issue and pull request when I saw your message. GitHub is a big family, and there are a lot of projects to contribute to in the meantime. Good luck coding! Regards, Maiyun
