Tag diff
========
This tool annotates diffs from geographical files.
Installation
------------
You may install the tool using:
.. code-block:: bash
$ python setup install --user
Example
-------
Suppose we have two tab-separated files, formatted like this (code, name, lat, lng):
.. code-block:: bash
$ head -n3 examples/2.txt
MLC Mc Alester Regonal Airport 34.882403 -95.783463
NDS Sandtone Airport -28 119.4
SPY San Pedro 4.746717 -6.660817
Now we do a unified diff between them:
.. code-block:: bash
$ diff -u examples/*.txt
--- examples/1.txt 2012-12-20 13:57:47.292866371 +0100
+++ examples/2.txt 2012-12-20 12:31:58.828420437 +0100

We want to annotate the differences in this diff to see which changes were:
+ a move (M)
+ a property change (P)
+ both (PM)
+ an addition (+)
+ a deletion (-)
+ no change (a space)
.. code-block:: bash
$ diff -u examples/*.txt | tag_diff -

*tag_diff* has added a column in first position where we see the tags P, M, PM, +, -, etc...
Options
-------
You can customize:
+ the columns where *tag_diff* is looking for code and geocodes with *-i*. This takes 3 arguments which are column indexes: key, lat and lng. key is the column used as an id for each line. Default is 0 2 3.
+ the delimiter with *-d*. Default is tabulation.
Displaying annotated differences
--------------------------------
You may use `GeoBases `_ to display the results like this (here we color using the column H0, the first column):
.. code-block:: bash
$ diff -u examples/*.txt |tag_diff - |GeoBase -m -M _ _ H0
