	Filename string
	Path     string
	// contains filtered or unexported fields
}

func NewUnitFile

func NewUnitFile() *UnitFile

Create an empty unit file, with no filename or path

func ParseUnitFile

func ParseUnitFile(pathName string) (*UnitFile, error)

Load a unit file from disk, remembering the path and filename

func (*UnitFile) Add

func (f *UnitFile) Add(groupName string, key string, value string)

func (*UnitFile) AddCmdline

func (f *UnitFile) AddCmdline(groupName string, key string, args []string)

func (*UnitFile) AddComment

func (f *UnitFile) AddComment(groupName string, comments ...string)

Empty group name == first group

func (*UnitFile) Dup

func (f *UnitFile) Dup() *UnitFile

Create a copy of the unit file, copies filename but not path

func (*UnitFile) GetTemplateParts

func (f *UnitFile) GetTemplateParts() (string, string)

func (*UnitFile) HasGroup

func (f *UnitFile) HasGroup(groupName string) bool

func (*UnitFile) HasKey

func (f *UnitFile) HasKey(groupName string, key string) bool

func (*UnitFile) ListGroups

func (f *UnitFile) ListGroups() []string

func (*UnitFile) ListKeys

func (f *UnitFile) ListKeys(groupName string) []string

func (*UnitFile) Lookup

func (f *UnitFile) Lookup(groupName string, key string) (string, bool)

Look up the last instance of the named key in the group (if any) The result have no trailing whitespace and line continuations are applied

func (*UnitFile) LookupAll

func (f *UnitFile) LookupAll(groupName string, key string) []string

Look up every instance of the named key in the group The result can have trailing whitespace, but line continuations are applied

func (*UnitFile) LookupAllArgs

func (f *UnitFile) LookupAllArgs(groupName string, key string) []string

Look up every instance of the named key in the group, and for each, split space separated words (including handling quoted words) and combine them all into one array of words. The split code is exec-like, and both unquotes and applied c-style c escapes.

func (*UnitFile) LookupAllKeyVal

func (f *UnitFile) LookupAllKeyVal(groupName string, key string) map[string]string

Look up 'Environment' style key-value keys

func (*UnitFile) LookupAllRaw

func (f *UnitFile) LookupAllRaw(groupName string, key string) []string

Look up every instance of the named key in the group The result can have trailing whitespace, and Raw means it can contain line continuations (\ at end of line)

func (f *UnitFile) LookupAllStrv(groupName string, key string) []string

Look up every instance of the named key in the group, and for each, split space separated words (including handling quoted words) and combine them all into one array of words.
