The text editor of NyxOS — open, edit and save files from the desktop.
Mnemosyne — named for the goddess of memory, mother of the Muses — is the text editor of NyxOS. It is the everyday way to read and write files on the desktop: a scrolling text buffer with line numbers, a cursor and line editing, an Open and Save bar, and the ext2 filesystem underneath.
It pairs with the in-OS cc toolchain: write a C (or .n) file in Mnemosyne, then compile and install it with xbm from Erebus, without ever leaving NyxOS.
Mnemosyne on the NyxOS desktop — Open / Save, line numbers and a fresh buffer
- Text buffer with line numbers, a cursor, insertion, deletion and scrolling
- Open / Save to the ext2 filesystem, with the current path shown in the toolbar
- Keyboard-driven editing through the compositor's key callback
- Opens as an ordinary Hemera window
Mnemosyne is one of the apps that live on top of Hemera, the NyxOS compositor. Today it is compiled into the kernel under kernel/gui/apps/editor_win.c; the roadmap is a standalone ring-3 ELF that opens its window through the window syscalls. This repository holds a source snapshot (src/).
| Component | Repo | Role |
|---|---|---|
| Hemera | hemera | the compositor / desktop |
| Erebus | erebus | the terminal |
| Selene | selene | the web browser |
| Mnemosyne | (here) | the text editor |
src/editor_win.c— the editor: buffer, rendering, input, open/savesrc/editor_win.h— the public interface
Built into the NyxOS kernel and running on the desktop today; the standalone-ELF split is the roadmap.
