Command-line based sqlite3 database explorer. The idea is to minimize typing of basic queries/tablenames and column names by allowing for selection of the same.

Some basic features:

• Lists databases in current folder and allows menu for selection.
• selection of tablenames from list, and of columns names and creates formatted output to a local temp file which is then displayed.
• bookmark/save common SQL queries and recall later.

Uses sqlite3 gem, readline for editing. In the case of columns, uses fzf for selection.

Also, uses 'term-table.rb' for formatting of output. This needs to be placed in your path as an executable.

You may replace that with your own formatter such as csvlook or column -t. However, these two crash on non-ascii characters on a Mac, so I've written a ruby replacement. You can forgo it entirely and just have comma or tab separated output sent to a file.

$ gem install cetusql
$ brew install fzf
$ brew install readline

run cetusql on the command line.

If no database name is passed, will prompt for one from *.db and *.sqlite files in current directory. After selection, one may select one or more tables from a list. Then one may select one ore more columns from a list. Edit the SQL statement if need be, and press ENTER. The output is displayed in vim using a temp file.

Use the menu to change table or database file, or set other options, save last SQL query, select from favorite queries, etc.

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
