Incrementally update the graph for changed files

Source: R/graph_index.R
update_graph_incremental.Rd

Re-parses only the files that have changed and merges the resulting nodes and edges back into the existing graph, avoiding a full rebuild. PageRank and embeddings are recomputed only for the affected portion of the graph, making single-file updates substantially faster than build_rrlm_graph().

Usage

update_graph_incremental(
  graph,
  changed_files,
  embed_method = NULL,
  verbose = FALSE
)

Arguments

graph

An rrlm_graph / igraph object previously built by build_rrlm_graph().

changed_files

Character vector of absolute file paths that have been added, edited, or deleted since the last full build.

embed_method

Character(1) or NULL. Embedding method passed to embed_nodes(). NULL (default) uses the method stored in graph_attr(graph, "embed_method"), falling back to "tfidf".

verbose

Logical(1). Emit progress messages via cli. Default FALSE.

Value

The updated rrlm_graph object. The graph retains all original vertex / edge attributes; only nodes from changed_files are touched.

Examples

if (FALSE) { # \dontrun{
g <- build_rrlm_graph("mypkg")
# After editing R/utils.R:
g <- update_graph_incremental(g, changed_files = "mypkg/R/utils.R")
} # }
