Docs

Docs may be generated with the docs command.

• Outputs to the docs directory.

Environment variables:

• MYSQL_SERVER
• MYSQL_USER
• MYSQL_PASS
• MYSQL_PORT

Commands (Generate docs for more info):

1. query

• Queries MYSQL_SERVER using the query file (and line number) specified in the arguments.
• If the option to generate an output file is enabled, the output file will be by the same filename as the input file.

1. session

• Opens a database session with MYSQL_SERVER.
• All queries ran during the session are piped to a session file which is generated in the .qdb-mysql under your user's home directory.
• Session filenames are generated with a unique timestammp.
• While the session is open, you may run a query or queries from any file and/or line number.

VSCode

This utility uses VSCode for some "glossy" functions.

• If you choose not to use VSCode, it is possible your editor can use the following features.

Features using VSCode:

1. Piping commands into the terminal based on keyboard shortcuts and selected line number.

• See .vscode/keybindings.json.
• These settings will need to be installed in you user settings.
• Example installation location (MacOS): /Users/<username>/Library/Application Support/Code/User/keybindings.json.

1. Opening SQL results into a new editor tab.

• See func openFile(file string) error in session.go.
• This is done automatically after each query.
• If a tab is already opened

Sub-Commands for session Command:

1. q ${file}:${lineNumber}

• Execute a query from a specific file ${file}, starting at line number ${lineNumber}.

1. q+ ${file}:${lineNumber}

• Same as above, but reopen the session file upon execution.

1. q ${file}

• Execute all queries query from a specific file ${file}.

1. q+ ${file}

• Same as above, but reopen the session file upon execution.

Noted Quirks

1. Leading comments are ran as empty queries instead of being extracted prior to execution.
2. When querying by line number, trailing comments can cause execution to continue.

• To stop this, just use ; without any comments when delineating queries.
