It uses sqlite to store necessary information, including snippet name, alias, filename, etc. The real file is stored in the txtFiles folder.

keystrokes for the application:

n	create a new snippet, a dialog will pop up for necessary information
j	move to next snippet
k	move to previous snippet
l	open the current snippet in the editor
d	delete current snippet, a dialog will pop up for ensurement

When a certain snippet is opened, we can edit it, save it, and copy it to the clipboard. Refer to the editor section below for greater details.

Related curses widgets

The widgets written are as follows:

itemlist

Itemlist displays the items as a list. use it as follows:

if __name__ == "__main__":
    from misc import set_win, unset_win
    from base import BaseWindow
    try:
        # make a main window first
        main = BaseWindow(main=True)
        set_win()

        # create an Itemlist
        itemlist = ItemList(0,0, mainwindow=main)

        # set or add items to it
        itemlist.setItem([a for a in "abcdefghijklmno"])
        itemlist.addItem("abcdefghijklmnopqrstuvwxyz")

        # loop over it
        itemlist.loop()

    except Exception as e:
        print(type(e), e)

    finally:
        unset_win()

where

def set_win():
    curses.start_color()
    curses.init_pair(1, curses.COLOR_GREEN, curses.COLOR_BLACK)
    curses.init_pair(2, curses.COLOR_RED, curses.COLOR_BLACK)
    curses.noecho()
    curses.cbreak()

def unset_win():
    curses.nocbreak()
    curses.echo()
    curses.endwin()

and it runs like this:

The ItemList uses vim-like keystroke to move between the items(k for up and j for down), and q for quitting.

dialogs

The InputDialog(prompt for user input), ProcessDialog(show the process of a certain process) and YesNoDialog(prompt for your choices, default for "yes" and "no") are supported at present.

# a dialog example for YesOrNo

if __name__ == "__main__":
    from misc import set_win, unset_win
    from base import BaseWindow
    try:
        main = BaseWindow(main=True)

        set_win()
        dialog1 = YesNoDialog(mainwindow=main)
        dialog1.promptYesOrNo("Are you sure to quit?")
        dialog1.clear()
        
        dialog2 = InputDialog(mainwindow=main)
        dialog2.showInput(["name", "age", "gender"], text="Input your infomation:")
    except Exception as e:
        print(type(e), e)
    finally:
        unset_win()

Run it and it first prompts like this (use h for left and l for right):

and after an "Enter" is entered, a form is shown to gather your info :)
