`svg|pipe` Transactions for existing SVG documents
==================================================

`inject` data and SVG content into an existing document, keeping its structure intact.

`extract` data and SVG content from an existing document (planned).

`transfer` data, attributes, etc. between existing SVG elements (planned).


Motivation
----------

Graphics applications are often picky (extremely picky) about the formatting of graphics documents. In order to have SVG files interpreted by your/everybodies favourite vector graphics application, the file structure not only needs to follow the SVG specs, but should follow a precise structure of layers, ids, and other unwritten conventions.

The project wants to facilitate transactions on existing documents for graphics-based workflows:

 + automated SVG generation (e.g. for data visualisation)
 + smooth integration with interactive vector graphics/CAD applications
 + automated data-import into complex pre-formatted graphics documents for visualisation


Philosophy
----------

`svg|pipe` not only uses SVG documents for import/export of graphical content into/from some existing stock of data. SVG documents are XML documents and can serve as data structures themselves.


Requirements and Installation
-----------------------------

Currently under development using:

* Python 3.7
* Pytest 5.2.2.


Tests
-----


### run tests

```
pytest
```


### visual inspection of test results

To get a file output of the SVG content involved in the testing:
+ Set environment variable `SVGPIPE_TEST_SVG_OUT` to point to the desired output directory.
+ Make sure the directory/folder exists.

After the test run, for each svg injection test there will be three SVG files:
+ `XXXX_test.svg` (before the injection)
+ `XXXX_result.svg` (what was actually the case after the injection)
+ `XXXX_expect.svg` (what should be the case after the injection)
