Yet another EmacSQL backend for SQLite

Introduction

This is yet another EmacSQL backend for SQLite, which use official sqlite3 executable to access SQL database.

Installation

emacsql-sqlite3 is available on melpa.

Usage

For Emacs users, please notice that this package won’t provide any feature for convenience. If you don’t sure you need this, you probably don’t need this.

For package developers, this package can be a replacement of emacsql-sqlite and it doesn’t require user to have a C compiler, but please read following precautions.

• You need to install sqlite3 official CLI tool, 3.8.2 version or above were tested, emacsql-sqlite3 may won’t work if you using lower version.
• sqlite3 CLI tool will load ~/.sqliterc if presented, emacsql-sqlite3 will get undefined behaviour if any error occurred during the load progress. It’s better to keep this file empty.
• This package should be compatible with emacsql-sqlite3 for most cases. But foreign key support was disabled by default. To enable this feature, use (emacsql <db> [:pragma (= foreign_keys ON)])

The only entry point to a EmacSQL interface is emacsql-sqlite3, for more information, please check EmacSQL’s README.

About Closql

closql is using emacsql-sqlite as backend, you can use following code to force closql use emacsql-sqlite3.

(with-eval-after-load 'closql
  (defclass closql-database (emacsql-sqlite3-connection)
    ((object-class :allocation :class))))

Known issue

The tests don’t pass under Emacs 25.1 for unknown reason, so we don’t support Emacs 25.1 currently like emacsql-sqlite. But any PR to improve this are welcomed.
