vsdx - A python library for processing Visio .vsdx files

.vsdx files can be processed in two ways, directly via python code as in example 1 below, or indirectly using a jinja template as in example 2

For quick start documentation please see https://vsdx.readthedocs.io/en/latest/quickstart.html

Example 1 code to find a shape with specific text, remove it, and then save the updated .vsdx file:

from vsdx import VisioFile

filename = 'my_file.vsdx'
# open a visio file
with VisioFile(filename) as vis:
  # get page shapes collection
  shapes = vis.pages[0]._shapes
  # get shape to remove by its text value
  s = shapes[0].find_shape_by_text('Shape to remove')  # type: VisioFile.Shape
  # remove the shape if found
  if s:
    s.remove()
    # save a new copy
    vis.save_vsdx('shape_removed.vsdx')

Example 2 creating a new vsdx file from a template and context data using jinja.
Note that as vsdx does not lend itself well to ordered statements like {% if something %}my content{% endif %} or {% for x in list_value %}x={{ x }}{% endfor %} this package provides mechanisms to help - refer to tests for more details.

from vsdx import VisioFile

filename = 'my_template_file.vsdx'  # file containing jinja code
context = {'value1': 10, 'list_value': [1,2,3]}  # data for the template
with VisioFile('my_template_file.vsdx') as vis: 
    vis.jinja_render_vsdx(context=context)
    vis.save_vsdx('my_new_file.vsdx')

Please refer to tests/test.py for more usage examples in the form of pytest tests.

Change Log

• v0.5.8: Add Page.master_base_id property
• v0.5.7: Add support for nested shapes in Page.all_shapes and Shape.all_shapes. Add Page.is_master_page and Shape.is_master_shape.
• v0.5.6: Fix error in Shape.text with missing master shape. Improve VisioFile.remove_page_by_index() and add VisioFile.remove_page_by_name().
• v0.5.5: Added Shape.universal_name and used in Shape.set_start_and_finish(). Set Page.page_id on open file.
• v0.5.4: Added better (but still incomplete) support for adding connectors between shapes
• v0.5.3: Fixed missing deprecation dependency in setup.py
• v0.5.2: deprecated Page.set_name() method and page.page_name property, in favour of Page.name. Unskipped test: test_shape_center(). Added find_shape.rst doc page
• v0.5.1: added Page/Shape.find_shape_by_property_label_value()/find_shapes_by_property_label_value()
• v0.5.0: deprecated Page.shapes property Page/Shape.sub_shapes() methods in favour of Page/Shape.child_shapes property. Add Shape.all_shapes property, convert Page.all_shapes() method to property
• v0.4.20: Shape.set_cell_value()/set_cell_formula() create new cell if missing, add Media().rectangle and circle props, add Shape.bounds, relative_bounds, and end_arrow props
• v0.4.19: correctly position new connector shapes between 'from' and 'to' shapes
• v0.4.18: add page.page_name, width and height properties
• v0.4.17: register xml namespaces to improve compatibility of xml output
• v0.4.16: Add Geometry class to read Shape geometry
• v0.4.15: Add requirement for Jinja2 to package
• v0.4.14: Include media/*.vsdx files in package
• v0.4.13: Fix for master shape property inheritance / value overrides
• v0.4.12: Add support for absolute paths
• v0.4.11: Add support for master shape data properties, with related tests
• v0.4.10: Add methods (Shape.find_shape_by_property_label() and Shape.find_shapes_by_property_label) to find shape or shapes by data property name.
• v0.4.9: Add support for creating new connection between two objects. Fix ShapeProperty.value, and add label, sort_key, value_type and prompt
• v0.4.8: Support nested loops/showifs and combo of loop and if in same shape.
• v0.4.7: Python 3.10.0rc1 added to test suite. Add Shape.data_properties property, and new class ShapeProperty to represent Visio Shape Data
• v0.4.6: Add support for nested jinja loops in one shape
• v0.4.5: Fix bug where some shapes have no parent, and inserting shape into empty page
• v0.4.4: Added support for master page shape inheritance, ability to get Shape.master_shape, ability to update master shapes and persist changes to master shapes in save_vsdx()
• v0.4.3: Added support for including/excluding pages via Jinja with {% showif <statement> %} in page name
• v0.4.2: Added VisioFile.add_page_at() method taking index to allow insertion at a specific point; Added VisionFile.copy_page() method to copy an existing page and insert at a specific index or relative to copied page (using PagePosition enum).
• v0.4.1: Added support for self referencing calculations in Jinja statements, such as {% set self.x = self x + n * 3.2 %}
• v0.4.0: Added VisioFile.jinja_set_selfs to allow setting shape x and y properties in Jinja template. Setting values, calculations, or if statements are supported e.g. {% set self.x = 1.5 %} or {% set self.y = n * 3 %} or {% set self.x = 1.0 if n else 2.0 %}
• v0.3.5: Added VisioFile.add_page() method and tests
• v0.3.4: Added VisioFile.remove_page_by_index() method to remove a page, with associated test
• v0.3.3: Added code of conduct and contributing guides
• v0.3.2: updated README and updated tests for improved compatibility
• v0.3.1: add jinja rendering support for if statements, via VisioFile.jinja_render_vsdx() - similar to for loops but using a {% showif statement %} in text of group shape controls whether that group shape is included in vsdx file rendered. Note that the showif statement is replaced with a standard if statement around the group shape prior to rendering. Refer to test.py::test_jinja_if() for an example
• v0.3.0: update jinja rendering to support for loops, where for statement is at start of group shape text, endfor is automatically inserted before processing. Refer to test.py::test_basic_jinja_loop() for code and test_jinja_loop.vsdx for content.
• v0.2.10: add VisioFile.jinja_render_vsdx() - applying jinja processing to Shape.text only
• v0.2.9: check that Page has shapes tag when in shape_copy(), add test to copy shape to new page
• v0.2.8: find max shape ID in Page before creating Shape in Shape.copy(). Find and load master pages when file is opened, store in VisioFile.master_page_objects and .master_pages
• v0.2.7: add Shape.copy() method
• v0.2.6: added Page.get_connectors_between() to get zero or many connectors between two shapes, by shape id or text
• 0.2.5: Add new Shape properties connected_shapes (list of Shape objects) and connects (list of Connect objects) properties to allow related shapes to be identified (i.e. shapes and connectors) and provide information on the relationship, in new Connect object. Also new properties of shape begin_x/y, end_x/y, plus height/width setters
• 0.2.4: Added find_replace(old, new) method to Shape and Page classes to recursively replace old with new
• 0.2.3: Updated tests to output files to an /out folder. Added test vsdx file with compound shape. Updated Shape text getter/setter
• 0.2.2: Added x & y location setters to Shape, and move(x_delta, y_delta) method - both with related tests
