Colored View
============
The `ColoredView` feature in `deepdiff` provides a human-readable, color-coded JSON output of the
differences between two objects. This feature is particularly useful for visualizing changes in a
clear and intuitive manner.
- **Color-Coded Differences:**
- **Added Elements:** Shown in green.
- **Removed Elements:** Shown in red.
- **Changed Elements:** The old value is shown in red, and the new value is shown in green.
Usage
-----
To use the `ColoredView`, simply pass the `COLORED_VIEW` option to the `DeepDiff` function:
.. code-block:: python
from deepdiff import DeepDiff
from deepdiff.helper import COLORED_VIEW
t1 = {"name": "John", "age": 30, "scores": [1, 2, 3], "address": {"city": "New York", "zip": "10001"}}
t2 = {"name": "John", "age": 31, "scores": [1, 2, 4], "address": {"city": "Boston", "zip": "10001"}, "new": "value"}
diff = DeepDiff(t1, t2, view=COLORED_VIEW)
print(diff)
Or from command line:
.. code-block:: bash
deep diff --view colored t1.json t2.json
The output will look something like this:
.. raw:: html
<pre style="background-color: #f8f8f8; padding: 1em; border-radius: 4px;">
{
"name": "John",
"age": <span style="color: #ff0000">30</span> -> <span style="color: #00aa00">31</span>,
"scores": [
1,
2,
<span style="color: #ff0000">3</span> -> <span style="color: #00aa00">4</span>
],
"address": {
"city": <span style="color: #ff0000">"New York"</span> -> <span style="color: #00aa00">"Boston"</span>,
"zip": "10001"
},
<span style="color: #00aa00">"new": "value"</span>
}
</pre>
Colored Compact View
--------------------
For a more concise output, especially with deeply nested objects where many parts are unchanged,
the `ColoredView` with the compact option can be used. This view is similar but collapses
unchanged nested dictionaries to `{...}` and unchanged lists/tuples to `[...]`. To use the compact
option do:
.. code-block:: python
from deepdiff import DeepDiff
from deepdiff.helper import COLORED_COMPACT_VIEW
t1 = {"name": "John", "age": 30, "scores": [1, 2, 3], "address": {"city": "New York", "zip": "10001"}}
t2 = {"name": "John", "age": 31, "scores": [1, 2, 4], "address": {"city": "New York", "zip": "10001"}, "new": "value"}
diff = DeepDiff(t1, t2, view=COLORED_COMPACT_VIEW)
print(diff)
Or from command line:
.. code-block:: bash
deep diff --view colored_compact t1.json t2.json
The output will look something like this:
.. raw:: html
<pre style="background-color: #f8f8f8; padding: 1em; border-radius: 4px;">
{
"name": "John",
"age": <span style="color: #ff0000">30</span> -> <span style="color: #00aa00">31</span>,
"scores": [
1,
2,
<span style="color: #ff0000">3</span> -> <span style="color: #00aa00">4</span>
],
"address": {...},
<span style="color: #00aa00">"new": "value"</span>
}
</pre>
