Find method invocations that resemble a pattern

io.moderne.ai.research.FindCodeThatResembles

This recipe uses two phase AI approach to find a method invocation that resembles a search string.

Recipe source

This recipe is only available to users of Moderne.

Options

TypeNameDescriptionExample
StringresemblesThe text, either a natural language description or a code sample, that you are looking for.HTTP request with Content-Type application/json
intkSince AI based matching has a higher latency than rules based matching, we do a first pass to find the top k methods using embeddings. To narrow the scope, you can specify the top k methods as method filters.5

Data Tables

io.moderne.ai.table.CodeSearch

Searches for method invocations that resemble a natural language query.

Column NameDescription
SourceSource
MethodMethod invocation
QueryNatural language query
Result of first modelsFirst two embeddings models result, where -1 means negative match, 0 means unsure, and 1 means positive match.
Called second modelTrue if the generative model was used.
Result of second modelSecond generative model's result.

Top-K Method Matcher

io.moderne.ai.table.TopKMethodMatcher

Result from the scanning recipe for top-k method patterns that match the query.

Column NameDescription
Method PatternMethod invocation pattern.
Method SignatureMethod invocation signature.
DistanceThe distance between the query and the method invocation.
QueryThe natural language search query.

Embedding performance

io.moderne.ai.table.EmbeddingPerformance

Latency characteristics of uses of embedding models.

Column NameDescription
Source fileThe source file that the method call occurred in.
Number of requestsThe count of requests made to the model.
HistogramThe latency histogram of the requests made to the model (counts). The histogram is a non-cumulative fixed distribution of 100 buckets of 0.01 second each.
Max latencyThe maximum embedding latency.

Generative model performance

io.moderne.ai.table.GenerativeModelPerformance

Latency characteristics of uses of generative models.

Column NameDescription
Source fileThe source file that the method call occurred in.
Number of requestsThe count of requests made to the model.
HistogramThe latency histogram of the requests made to the model (counts). The histogram is a non-cumulative fixed distribution of 100 buckets of 1 second each.
Max latencyThe maximum embedding latency.

Suggested method patterns

io.moderne.ai.table.SuggestedMethodPatterns

As the next step after the AI-based searching for method invocations, you may want to do rule-based method searching using the recommended method patterns.

Column NameDescription
MethodMethod invocation
Method PatternMethod invocation pattern.
QueryThe natural language search query.

Source files that had results

org.openrewrite.table.SourcesFileResults

Source files that were modified by the recipe run.

Column NameDescription
Source path before the runThe source path of the file before the run. null when a source file was created during the run.
Source path after the runA recipe may modify the source path. This is the path after the run. null when a source file was deleted during the run.
Parent of the recipe that made changesIn a hierarchical recipe, the parent of the recipe that made a change. Empty if this is the root of a hierarchy or if the recipe is not hierarchical at all.
Recipe that made changesThe specific recipe that made a change.
Estimated time savingAn estimated effort that a developer to fix manually instead of using this recipe, in unit of seconds.
CycleThe recipe cycle in which the change was made.

Source files that errored on a recipe

org.openrewrite.table.SourcesFileErrors

The details of all errors produced by a recipe run.

Column NameDescription
Source pathThe file that failed to parse.
Recipe that made changesThe specific recipe that made a change.
Stack traceThe stack trace of the failure.
