# Hashpyre...

A simple "language" to insert hashmaps to Redis.

# Usage

Invoke the script with the following arguments:

- **_file_** _required_  

Indicates the filename of the hashmap inserts. Must be the _last_ string passed as an argument.

- **-host** _required_  

The Redis server host IP.

- **-port** _required_  

The Redis server host port.

- **-password**  

The Redis server password, when applicable.

**Sample Invocation**

    python hashpyre.py -host localhost -port 6379 inserts.txt

To invoke `hashpyre` on a file named `inserts.txt` to be inserted on the local Redis server at port 6379.

# Insert File Structure

There are four kinds of lines/statements in an insert file:

- **Map name declaration**  

A map name is a single word consist of alphanumeric or underscore characters in a line all by itself. This

is used as the name of the map once inserted to Redis.

- **map()**  

Inserts all the assignment lines _after the last invocation of map()_ as a single hash map in Redis. This

throws an error if a new map name has not been declared since the last map() invocation.

- **Assignment lines**  

Most probably going to be the most common line in an insert file. Sets a key-value pairing for the current hashmap.

Assignment lines are of the form:

    [KEY] :[VALUE]

Where key is a single word consist of alphanumeric or underscore characters and value is a string made up of alphanumeric

and punctuation characters with possible spaces. Note that there may be any number of spaces between the key and colon but

everything after the colon is considered part of the value.

- **Comments**  

Comments are lines that start with the hash character (`#`). These lines (along with blank lines) are ignored by

Hashpyre.

**Sample Insert File**

    # This is a comment. It will be ignored by Hashpyre.

    

    # The following line is a hash name. Though not required,

    # it is a good idea to declare the hash name right after the

    # last map() invocation (or, in this case, the start of the file).

- Allow quoted values for the key-value pairings for better whitespace management.
