Functions

func ExtractLineFragment

func ExtractLineFragment(line, substr string, key bool) string

ExtractLineFragment will prepare substr for line detection

func GenerateSubstrings

func GenerateSubstrings(key string, extractedString [][]string) (substr1Res, substr2Res string)

GenerateSubstrings returns the substrings used for line searching depending on search key '.' is new line '=' is value in the same line '[]' is in the same line

func GetAdjacentVulnLines

func GetAdjacentVulnLines(idx, adj int, lines []string) []model.CodeLine

GetAdjacentVulnLines is used to get the lines adjacent to the line that contains the vulnerability adj is the amount of lines wanted

func GetBracketValues

func GetBracketValues(expr string, list [][]string, restOfString string) [][]string

GetBracketValues gets values inside "{{ }}" ignoring any "{{" or "}}" inside

func GetLineBySearchLine

func GetLineBySearchLine(pathComponents []string, file *model.FileMetadata) (int, error)

GetLineBySearchLine makes use of the gjson pkg to find the line of a key in the original file with it's path given by a slice of strings

func SelectLineWithMinimumDistance

func SelectLineWithMinimumDistance(distances map[int]int, startingFrom int) int

SelectLineWithMinimumDistance will search a map of levenshtein distances to find the minimum distance

Types

type DefaultDetectLineResponse

type DefaultDetectLineResponse struct {
	CurrentLine     int
	IsBreak         bool
	FoundAtLeastOne bool
	ResolvedFile    string
	ResolvedFiles   map[string]model.ResolvedFileSplit
}

DefaultDetectLineResponse is the default response for struct DetectLine

func (*DefaultDetectLineResponse) DetectCurrentLine

func (d *DefaultDetectLineResponse) DetectCurrentLine(str1, str2 string, recurseCount int, lines []string) (*DefaultDetectLineResponse, []string)

DetectCurrentLine uses levenshtein distance to find the most accurate line for the vulnerability

type DetectLine

type DetectLine struct {
	// contains filtered or unexported fields
}

DetectLine is a struct that associates a kindDetectLine to its FileKind

func NewDetectLine

func NewDetectLine(outputLines int) *DetectLine

NewDetectLine creates a new DetectLine's reference

func (*DetectLine) Add

func (d *DetectLine) Add(detector kindDetectLine, kind model.FileKind) *DetectLine

Add adds a new kindDetectLine to the caller and returns it

func (*DetectLine) DetectLine

func (d *DetectLine) DetectLine(file *model.FileMetadata, searchKey string, logWithFields *zerolog.Logger) model.VulnerabilityLines

DetectLine will use the correct kindDetectLine according to the files kind if file kind is not in detectors default detect line is called

func (*DetectLine) GetAdjecent

func (d *DetectLine) GetAdjecent(file *model.FileMetadata, line int) model.VulnerabilityLines

GetAdjecent finds and returns the lines adjecent to the line containing the vulnerability

func (*DetectLine) SetupLogs

func (d *DetectLine) SetupLogs(logger *zerolog.Logger)

SetupLogs will change the logger feild to be used in kindDetectLine DetectLine method

func (*DetectLine) SplitLines

func (d *DetectLine) SplitLines(file *model.FileMetadata) []string

SplitLines splits lines splits the file by lines based on the type of file
