Есть ли приложение, которое связывает заметки с заметками в окне, на основе названия окна?

Ну, я снова нахожусь на кривой обучения ... (поздние ночи и много кофе).

Конечным результатом является умеренно используемый bash-скрипт (с использованием sqlite db / table), который делает то, что я был после ... ... т.е. Создает группировку заметок, основанных на названиях окон ...

Это работает .. но это определенно «альфа» ..

Итак, у меня есть мое домашнее приложение ! ... Я размещаю его здесь для всех, кто интересуется «смотри-смотри» ...

Вот он:

#!/bin/bash

clearAllDataAndStartAgain="false"

# Name: tinotes (Title Notes)
# 
# What does it do? ... Aside from giving me a great opportunity to learn
#      more about bash (and sqlite, which I had previously barely touched).. not much ;)
#      Actually, it allows you to keep notes, grouped by window title.
#      The notes are kept in an sqlite database. 
#      Each timestamped note-"event" is stored in a row of the main (only) table.
#      You can consolidate notes in a semi ad-hoc manner... 
#      Notes are presented to you in a single editable text file (in Leafpad).  
#      You must keep at least one "tinotes" timestamp-line at the top of the text...
#      All lines above this topmost timestamp-line are ignored,
#      including the "title", which is presented upon each viewing.
#      If you remove any/all other "timestamp line(s)", those particular rows are 
#      deleted from the sqlite table, and the text which remains is associated with
#      the immediately preceding timestamp-line (and updated as such in the sqlite table)
#         
# How do you drive it? .. Just associate `tinotes.sh` with a shortcut-key.. That's' it!
#      Just press the shortcut-key and you will be presented with Leafpad displaying 
#      a  "title line" at the very top, and on line 2, is a "tinotes timestamp" line.  
#      Type your note below the  timestamp-line, then Save and Exit Leafpad,..
#      NB.. You MUST fully EXIT Leafpad.. the script cannot proceed until you EXIT Leafpad..
#      Leafpad is effectively being used as a Dialog-box with "normal" editing capability.
#      A warning Dialog appears if another instance of this script is currently running.. 
#      (actually, if another ***tinotes** leafpad window is running).
#             
# Caveat: This version is very much "demo-only"... 
#         It works, but has typical "alpha" bugs... 
#         I've presented it here, for anyone who is interested in the general idea.

Ну, я снова учился на учебе ... (поздние ночи и много кофе).

Конечным результатом является умеренно используемый bash-скрипт (с использованием sqlite db / table), который делает то, что я был после ... ... т.е. Создает группировку заметок на основе оконных заголовков ...

Это работает .. но это определенно «альфа» ..

Итак, у меня есть мое домашнее приложение ! ... Я размещаю его здесь для всех, кто интересуется «смотри-смотри» ...

Вот он:

#!/bin/bash

# Name: tinotes (Title Notes)
# 
# What does it do? ... Aside from giving me a great opportunity to learn
#      more about bash (and sqlite, which I had previously barely touched).. not much ;)
#      Actually, it allows you to keep notes, grouped by window title.
#      The notes are kept in an sqlite database. 
#      Each timestamped note-"event" is stored in a row of the main (only) table.
#      You can consolidate notes in a semi ad-hoc manner... 
#      Notes are presented to you in a single editable text file (in Leafpad).  
#      You must keep at least one "tinotes" timestamp-line at the top of the text...
#      All lines above this topmost timestamp-line are ignored,
#      including the "title", which is presented upon each viewing.
#      If you remove any/all other "timestamp line(s)", those particular rows are 
#      deleted from the sqlite table, and the text which remains is associated with
#      the immediately preceding timestamp-line (and updated as such in the sqlite table)
#         
# How do you drive it? .. Just associate `tinotes.sh` with a shortcut-key.. That's' it!
#      Just press the shortcut-key and you will be presented with Leafpad displaying 
#      a  "title line" at the very top, and on line 2, is a "tinotes timestamp" line.  
#      Type your note below the  timestamp-line, then Save and Exit Leafpad,..
#      NB.. You MUST fully EXIT Leafpad.. the script cannot proceed until you EXIT Leafpad..
#      Leafpad is effectively being used as a Dialog-box with "normal" editing capability.
#      A warning Dialog appears if another instance of this script is currently running.. 
#      (actually, if another ***tinotes** leafpad window is running).
#             
# Caveat: This version is very much "demo-only"... 
#         It works, but has typical "alpha" bugs... 
#         I've presented it here, for anyone who is interested in the general idea.
#

#      leafpad .. to edit/view the notes (no need to re-invent the wheel)
#       wmctrl .. to detect if a ***tinotes*** leafpad window is currently open.
#      xdotool .. to get the active window's' ID
#     xwininfo .. to get a window's title via it's ID.
