Save My Tabs ============ DESCRIPTION =========== Save My Tabs is an extension for Google Chrome that periodically saves info on all of your open tabs to SQLite databases (window and tab numbers, URL and title of each tab). Script files for Windows and Linux are bundled (see below) to help users extract data from these databases. USAGE ===== Save My Tabs doesn't require any user intervention. Every several minutes, as defined by it's preferences, extension creates a new local database file in the extension's databases directory. This directory is in user Data directory, as defined in: http://www.chromium.org/user-experience/user-data-directory and the path to databases is: [user data dir]\Default\databases\chrome-extension_[extension id]_0 Each database contains info on all open tabs user had kept opened by the time the file was created. Each database contains 2 tables: - 'save_my_tabs_options': contains a single record with the name of database in the 'name' field; - 'save_my_tabs_records': contains records on open tabs. Each record contains window index ('winindex' field), tab index within the window ('tabindex'), URL of tab ('url') and tab title ('title'). Default backup period is 15 minutes. User can change this value through the Options page: navigate your Chrome to 'chrome://extensions' URL, and click "Options" link of "Save My Tabs" extension. "Update" button saves the new value of backup period. PACKAGING ========= The .crx file can be created with the help of Chrome browser. Navigate the Chrome to 'chrome://extensions' URL, expand the 'Developer mode' selector (right side of 'Extensions' band), click on 'Pack extension' button and choose the directory where source files are. INSTALLATION ============ The extension can be installed either by drag-and-dropping the 'savemytabs.crx' file over an existing Chrome window, or, if you have the extension source files unpacked, by navigating Chrome to 'chrome://extensions' URL, expanding the 'Developer mode' selector (right side of 'Extensions' band), clicking 'Load unpacked extension' and choosing the folder where the source files are. EXTRACTING DATA =============== 1. Prerequisites. Before extracting the data from database files, you should have the following at hand: - SQLite executable for your operating system. Precompiled binaries for some operating systems can be downloaded from: http://www.sqlite.org/download.html - Extension ID. This can be retrieved from the Chrome's extensions control page ('chrome://extensions'); ID is 32-symbol string just below the description of 'Save My Tabs'. - path to the user's database directory, derived from the extension ID (above) and user data directory path, as defined in: http://www.chromium.org/user-experience/user-data-directory Database path is: [user data dir]/databases/chrome-extension_[extension id]_0/ 2. Extraction procedures. Bundled with the extension are the batch file (Windows) and bash script (Linux) that will help with the data extraction. Before running the scripts, one should: - get the extension id (see above); 2.1. Windows: - ensure that "save-my-tabs-id" variable in the batch file is equal to the extension id, so script has a correct path to the database files; - be sure to have the SQLite 3 executable accessible (or just placed in the same directory where the batch file is). You can download the Windows binary from sqlite.org site. Run the "extract.bat" to extract the data from Chrome user databases to the tab-separated files. Script creates one or more (equal to the number of new databases created by extension) .txt files in the same directory where the batch file is. Note that "extract.bat" file can be run from any directory, given the SQLite executable is in the same directory (or available through the environment) and paths in the batch file are correct. 2.2. Linux: - ensure that "save_my_tabs_id" variable in the bash script is equal to the extension id, so script has a correct path to the database files; - ensure that "save_my_tabs_user" variable in the bash script is equal to your user name, so script has a correct path to the database files. - be sure to have the sqlite3 package installed. You can check it's existance with "sqlite3 -version" command through the terminal. When all of the above is done, you can run "sh extract.sh" through the terminal. Script will create the appropriate text files in your current directory. AUTHORS ======= Copyright 2010 Joseph Turian. Developed by Dmitriy Khudorozhkov.
