velorek1 / c-edit

A text editor in C with drop down menus from scratch. No ncurses.

C-EDIT Project in C language (NO NCURSES)

C-EDIT for linux - IN PROGRESS - A linux text editor in the style of the MSDOS EDIT - WITHOUT USING NCURSES

• WARNING: DO NOT EDIT YOUR PRECIOUS FILES WITH THIS EDITOR!!

Check TODO list to keep updated on the progress: 2024 -> Currently adding the Dynamic buffer (vector of lines) -> tests in https://github.com/velorek1/ceditbuf 2022 -> I have rewritten the screenbuffer and fixed polling issues (lynx: https://github.com/velorek1/lynx). Ideally, a keyboard library abstraction would be nice to expand the editor's possibilities.

TO INSTALL:

* Download or clone repository.
* Type "cd src", "make" and "./cedit" to execute.

So far I have implemented:

• A very simple Double Screen Buffer with a simple linked list in memory for greater display control.
• Rudimentary Text User Interface with Windows, Textbox, Keyboard handling, Color schemes, etc.
• Automatic display resizing.
• Open file dialog with a Listbox and SCROLL capabilities to navigate and find the file to open.
• Rudimentary Edit buffer with vertical scroll.
• A millisecond timer for animations.

Files in /src/:

• rterm.c -> code for the library that handles output with Ansi Functions and kbhit() in linux console (with its header file)
• list.c -> code for the circular linked list responsible for handling menus
• scbuf.c -> code for controlling display with a double screen buffer (with its header file)
• keyb.c -> module to control keyboard input.
• opfile.c -> module that list files with scroll capabilities to select the file to open.
• uintf.c -> module with user interface widgets: alert windows, confirmation windows, textbox, etc.
• fileb.c -> module for single file operations.
• tm.c -> module for a millisecond timer for animations (C11)
• main.c -> Editor in C in the style of MSDOS EDIT (In progress).

As a screen buffer I have implemented a dynamic structure in memory that allows to save the current screen so that you can display new things on top and then go back to the previous (saved) screen. (simple linked list)

c-edit's Issues

Backspace Key

I do not understand why the backspace key does not delete the characters as in any normal editor

Crashes on NetBSD and OpenBSD

Compiles well but when ran the main screen is partially displayed before crashing:

On OpenBSD it even disconnects the SSH session. Email me at [email protected] if you want to test for yourself, I can give you an account on my server.

Box drawing glitches on FreeBSD

The box drawing lines are missing and the colors are off when running on FreeBSD:

Improve portability

Nice project!

I just tried to build C-edit under Serenity OS and got this far:

Apparently you can use stat instead of d_type to make it more portable. Apparently d_type is a BSDism.
