An implementation of a command line text editor written in Golang as part of a course project for CS455 (2023-24 I Sem.) in a team of four (Abhishek "abhishekshree" Shree, Jahnvi "Janhvi-Rochwani" Rochwani, Parinay "parinayc20" Chauhan, and me, Aditya "cliche-niche" Tanwar).

Running

To compile the project, please ensure you have 1.21x (or a higher) version of Go installed. Thereafter, you can simply clone the repository and run the following commands:

go build main.go
./main -location="."

Alternatively, after building the project, you can also run ./main -location=filename.txt or ./main. The differences between the three usages are:

• ./main -location="path/to/directory/: Opens the editor in the directory given in the path with an interactive view of the directory available on the left.
• ./main -location=".": Opens the editor in the same directory as the executable is in.
• ./main -location="filename.ext": Opens just the give file (and not a directory).

Features

Upon opening a file, the editor supports features like:

• Basic editing (cut, copy, paste, undo, redo, etc.)
• Navigation using keys as well as key combinations
• Navigation using scrolling
• Autosave (at regular intervals of 30s)
• Reminder to save a file before closing
• Keyboard shortcuts:
  • Ctrl-C: Close the application
  • Ctrl-Q: Copy text if there is any selection. If there is no selection, copy the line the cursor is in
  • Ctrl-X: Cut text if there is any selection. If there is no selection, cut the line the cursor is in
  • Ctrl-V: Paste previously copied/cut text
  • Ctrl-S: Save all changes to the file
  • Ctrl-O: Toggle autosave on/off (initially off)
  • F1: Display help containing shortcuts and more
  • Some of these shortcuts are available on the front page as well when the application is run
