Create rough call diagrams for Python applications. Pyyan will take one or more Python sources, perform a (rather superficial) statistical analyze and create a directional chart of the entities in the merged resource and how they mutually identify or use each other. You can use GraphViz or yEd to render the graphic.

Now also for Phython 3! You can assign file names and line numbers to the node. Pyan's statistical analytical method is different from executing the program and seeing which features are invoked how often. A number of different utilities are available that create a call diagram in this way, usually using a debtugger or profile tracing hook, such as for example using Pyton Call Graph.

Refer to Pyan -- Help. When the graphic is not readable due to too many details, you should only visualise a partial set of data in your projects. At the moment, Pyan always works at the function and method levels; an ability to display relationships between name spaces only may (or may not) be added in a later release.

Diagram creation: On the old Pyan, call of passed method of contract_nonexistents() followed by expand_unknowns() were included, but this often creates wrong borders (because the placeholder is extended to *. name for all names of objects that have an attribut named name). Conflicts between the names of a variable and a function or class that has been specified elsewhere no longer confuses Pyan.

Note that the understanding of the lists has a specific area (which is handled as a function) only in version 3. Thus, when Pyan3 is used on older Pyan 2 codes, it will give subtle false results when the understanding of the codes is used. When grouping is enabled, only the name of the file and the line number are specified, since the group header already displays the group name.

Specify the safety of the recognized borders (probability that the border is correct). Completely resolvable name references backed by encyclopedic scanning have Trust 1.0. Referring to an unfamiliar name has trust 0.0. Completely exploded references to a known property of a known item have Trust 1.0. References to attributes of unfamiliar objects have a trust of 0.0.

Wildcards and their extensions have trust 0.0. Trust levels may need to be updated in Passport 2. Method prefixes by classname in diagram; Creating annotation legends. Scanning the knots and borders, essentially creating a new chart and visualizing it. There may be a need for a second visit category at a given point, which is only a catch-all that will extract the name and then apply only to related twigs of the ASP.

Supports empty list (for exploding methods for . append() and the like). Supplementary generalisations for unwrapping (PEP 448, Python 3.5+). Must recognize base enums during ClassDef analyses; then mark the classes as enums and treat them differently. Resolve the results of functions invoked, except for a very restricted exception for super().

Notes on models (PEP 484, Python 3.5+). Both can be used to link the name of the functional parameters to the corresponding item categories, thus eliminating the need for wildcards (especially for attributes that are transferred as functional arguments). You could execute run 3 with extra information from the state of the chart after run 2 to link call points with functional definition.

It would allow some wild cards to be resolved by locating the current state of the game. At the call location, must be able to determine whether or not the first position parameter in the call is treated deflicitly. Cython; could remove or annotate Cython-specific codes as a preprocessing stage, then handle them as Python (must make sure that the line numbers are correct).

This last one contains functions that are called; the name of the functions then appear in a loading connection within the branch. Binding is traced with encyclopaedic scanning to identify which kind of objects or functions each name points to anywhere in the sources to be constructed-. Also the analyser has to follow the kind of objects it is pointing to.

As Python does, a metodefinition captures the verbal name that self represents from the arguments as Python does; then this name points to the actual classes in the dictionary area of this metod (since Pyan only takes care of objects and not of instances). Obviously, this easy way cannot properly follow the cases where the actual bind of self. f is dependent on the order in which the classes techniques are used.

In order to keep things easy, Pyan chooses to disregard this complexity, simply read the source codes linearly (twice to include all forward references) and use the most recent bindings currently in range. In the case of a mandatory instruction, the extent to which the new value for the name is to be saved is determined by the actual name range.

Likewise, the actual name space defines which item types or functions are to be selected as users. Genuine pyan py by Edmund Horner. The Python 3 ports, analyser extension and extra Juha Jeronen re-factoring.
