Variables

View Source 
var DEFAULT_LINE_ATTRIBUTES = []string{
	"author", "lmkr", "insertorder", "start",
}

Some of these attributes are kept for compatibility purposes. Not sure if we need all of them

View Source 
var LineAttributes = []string{lineMarkerAttribute, "list"}

If one of these attributes are set to the first character of a line it is considered as a line attribute marker i.e. attributes set on this marker are applied to the whole line. The list attribute is only maintained for compatibility reasons

type TextLinesMutator added in v0.0.2 

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

TextLinesMutator is a class to iterate and modify texts which have several lines. It is used for applying Changesets on arrays of lines.

Mutation operations have the same constraints as exports operations with respect to newlines, but not the other additional constraints (i.e. ins/del ordering, forbidden no-ops, non-mergeability, final newline). Can be used to mutate lists of strings where the last char of each string is not actually a newline, but for the purposes of N and L values, the caller should pretend it is, and for things to work right in that case, the input to the Insert method should be a single line with no newlines.

func NewTextLinesMutator added in v0.0.2 

func NewTextLinesMutator(lines *[]string) *TextLinesMutator

NewTextLinesMutator creates a new TextLinesMutator with the given lines. Lines are mutated in place.

func (*TextLinesMutator) Close added in v0.0.2 

func (m *TextLinesMutator) Close()

Close closes the splice.

func (*TextLinesMutator) GetLines added in v0.0.2 

func (m *TextLinesMutator) GetLines() []string

GetLines returns the current state of the lines.

func (*TextLinesMutator) HasMore added in v0.0.2 

func (m *TextLinesMutator) HasMore() bool

HasMore checks if curLine (the line we are in when curSplice is applied) is the last line in lines. Returns true if there are lines left.

func (*TextLinesMutator) Insert added in v0.0.2 

func (m *TextLinesMutator) Insert(text string, L int) error

Insert inserts text into lines array.

func (*TextLinesMutator) Remove added in v0.0.2 

func (m *TextLinesMutator) Remove(N, L int) string

Remove removes text from lines array.

func (*TextLinesMutator) RemoveLines added in v0.0.2 

func (m *TextLinesMutator) RemoveLines(L int) string

RemoveLines removes whole lines from lines array.

func (*TextLinesMutator) Skip added in v0.0.2 

func (m *TextLinesMutator) Skip(N, L int, includeInSplice bool)

Skip skips some characters. Can contain newlines.

func (*TextLinesMutator) SkipLines added in v0.0.2 

func (m *TextLinesMutator) SkipLines(L int, includeInSplice bool)

SkipLines skips some newlines by putting them into the splice.
