Commandline LevelDB management.
- Command line data management
- Interactive data management
- REPL features auto-complete and suggestions for keys.
- REPL automatically saves and reloads REPL history.
- Connect to a network enabled database via multilevel.
$npm install lev -g$ levWill print out usage options. Note most commands have shorthand aliases
Get the first 10 keys in the database, the path is optional but if ommited a database will be created in the current working directory.
$ lev path/to/db --keys --limit 10or short hand
$ lev path/to/db -kl 10Get the first ten records starting at bazz and ending at zomg.
$ lev path/to/db --limit 10 --start 'bazz' --end 'zomg'Get the key welcome from inside the 2 sublevels deep
lev ./db --cd greetings/en --get 'welcome'If no options are supplied then a REPL is provided to either the path or port specified
Options:
-c Creates a database
--del, -d Remove an entity
--get, -g Get an record based on the key
--put --value, -p Put a value into the database
e.g $ lev /path/to/db --put key --value val
Or $ lev /path/to/db -p key val
--port For connecting to a remote multilevel instance.
Use as a single option for a REPL
--keys, -k Only return keys
--limit, -l The number of entities to return
--start, -s The starting key for a read
--end, -e The end key
For connecting to a multilevel enabled instance, specify the port parameter:
lev --port 1337 --keys ...
Start the REPL by providing only a path or host and port
$lev path/to/dbCommands in the REPL also match the API. But wait! There are a subset of commands
that make common operations faster, easier and more fun. The following keys and
sublevels are arbitrary and for the purpose of this example only.
Supports tab completion, same as the javascript function.

You can create a .lev file in your home directory and it will be used to set
the defaults. Command line arguments will override the default settings in this
file.
