====== SolvitDB library ======

The ``solvitdb`` library is a part of [[solvit|lib:solvit]] and it is the part that can read and modify .svt (Solvit Database) files.

===== Solvit Database format =====

==== Specification ====

4 bytes - length of the PAT (little endian uint32)\\ 
4 bytes - ``RTFM`` magic bytes\\ 

=== PAT ===

For each package:

n bytes - package name\\ 
1 byte - ``.``\\ 
4 bytes - package data start location (not including the length of the PAT or other things at the start) (little endian uint32)\\ 
1 byte - ``;``

=== Package data ===

For each package:

1 byte - package type (``P`` - package, ``G`` - group, ``V`` - virtual package)\\
n bytes - one or multiple series (described below)\\ 
1 byte - newline, package data end marker

== Series ==

There can be multiple series in the data for one package. Described below will be one single series, however they can be chained without any additional separators.

1 byte - series type (``d`` - dependencies, ``D`` - reverse dependencies, ``c`` - conflicts, ``p`` - packages (if it is a group or vpackage))

For each item:

n bytes - item name
1 byte - series separator, ``;`` unless it is the last item in the series, in which case it is ``.``

==== Notable design features ====
  * Compact
  * Readable without loading the entire file (which can get pretty big) into RAM
