Overview

Package search provides client-side repository searching.

This supports building an in-memory search index based on the contents of multiple repositories, and then using string matching or regular expressions to find matches.

Functions

func SortScore

func SortScore(r []*Result)

SortScore does an in-place sort of the results.

Lowest scores are highest on the list. Matching scores are subsorted alphabetically.

Types

type Index

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

Index is a searchable index of chart information.

func NewIndex

func NewIndex() *Index

NewIndex creats a new Index.

func (*Index) AddRepo

func (i *Index) AddRepo(rname string, ind *repo.IndexFile, all bool)

AddRepo adds a repository index to the search index.

func (*Index) All

func (i *Index) All() []*Result

All returns all charts in the index as if they were search results.

Each will be given a score of 0.

func (*Index) Chart

func (i *Index) Chart(name string) (*repo.ChartVersion, error)

Chart returns the ChartVersion for a particular name.

func (*Index) Search

func (i *Index) Search(term string, threshold int, regexp bool) ([]*Result, error)

Search searches an index for the given term.

Threshold indicates the maximum score a term may have before being marked irrelevant. (Low score means higher relevance. Golf, not bowling.)

If regexp is true, the term is treated as a regular expression. Otherwise, term is treated as a literal string.

func (*Index) SearchLiteral

func (i *Index) SearchLiteral(term string, threshold int) []*Result

SearchLiteral does a literal string search (no regexp).

func (*Index) SearchRegexp

func (i *Index) SearchRegexp(re string, threshold int) ([]*Result, error)

SearchRegexp searches using a regular expression.

type Result

type Result struct {
	Name  string
	Score int
	Chart *repo.ChartVersion
}

Result is a search result.

Score indicates how close it is to match. The higher the score, the longer the distance.
