Simple Patch Toolkit

====================

SPT or Simple Patch Toolkit is a tool for writing a robust patch with its Domain Specific Language (DSL).

With the SPT language, we can easily patch a text file with search and replace syntax.

This allows us to write robust patches to support multiple-version and frequently-evolved source codes.

For example,

    useTabs = true

    name "001 Add new splitter ID to allfilters"

    patch "include/mediastreamer2/allfilters.h"

        check  "\tMS_SPLITTER_ID"

        find   "} MSFilterId;"

        offset (-1) append ","

        insert "\tMS_SPLITTER_ID"

        commit

    done

Patch in the example check to see if there exists `MS_SPLITTER_ID` defined in `MSFilterId`.

If there's a line containing `MS_SPLITTER_ID`, SPT will throw an exception and stop the patching process.

If not, it then locates the line `} MSFilterId;` as the current line.

Then appends `,` to the line prior the current line.

Next, the patch inserts a new line containing to `MS_SPLITTER_ID` prefixed with a TAB just before the current line.

Then saves this change as a `Git` commit and automatically generate a `diff` file for us.

The `name` command will be used as the commit's message, and the diff's filename.

With SPT, we'll have a Git-compatible robust patch DSL engine to help maintain our changesets against the fast moving projects.
