This project defines two stages of project analysis, which can be used to drive delivery decisions and to classify projects.
The two stages are:
ProjectAnalysis
is the elements
property, whose value is an indexed type which values
of type TechnologyElement
. Because a ProjectAnalysis
is designed to be
serialized and persisted it contains only data, and no functions.ProjectAnalysis
but not source
code, so can be run on persisted analyses. An Interpretation
is computed
when necessary and not serialized to JSON, so it can specify functions and
delivery goals.Analysis and interpretation is designed to be extensible. Additional "scanners" and "interpreters" can be added wtihout affecting existing capabilities.
Two additional concepts are principally relevant to offline use, to classify projects and provide a basis for project querying:
TransformRecipeContributor
implementations
to contribute parameters and transforms that can enable any project to
be used as a seed. This "contribution" model ensures that we avoid the Cartesian product
problem with seeds: E.g. if we care about AWS Lambda and Kubernetes, Node and Spring,
we don't need 4 distinct generators (Lambda/Node, Lambda/Spring, Kube/Node and Kube/Spring),
but can use one "universal" generator that applies whichever contributions are
relevant to the current seed.Seed analysis is only performed when a project analysis is performed with the full
option flag
set to true. Scanner registrations that return technology elements can also specify
whether or not they should fire depending on the invocation options. This is important
for scanners that are expensive, such as calculation of the number of lines of code
in a repository, which requires reading every file. Typically, such analyses
are performed only infrequently, and persisted for future use.
