Modify plugin

Allows to modify parameters of existing graph elements.

Compile with:

go build -buildmode=plugin -ldflags="-w" -o modify.so ./*.go

Configuration

YAML definition's data fields:

• group: as all graph nodes belong to some group/type, it can be used to apply modifications to the specific group only
• modify: list of replacements. If regex matches node/edge's field value - put replacement instead

More info about used function: https://pkg.go.dev/regexp#Regexp.ReplaceAllString, where: - MustCompile receives regex - ReplaceAllString receives graph field value and replacement

List of replacements example:

modify:
    - field: field_name
      regex: a(x*)b
      replacement: y

    # Anonymize prices
    - field: price
      regex: (?i)\d{1,3}(?:[.,]\d{3})*(?:[.,]\d{2}) *(eur|€)
      replacement: *** Eur
