func ResetVersionSectCnts

func ResetVersionSectCnts(tag string)

ResetVersionSectCnts resets the counters to control the error message of missing or wrong version section the warning message for the use of old style version section needed for staging to get the Warnings and Errors displayed

func StoreSectionInfo

func StoreSectionInfo(obj *INIFile, file, ID string, overwriteExisting bool) error

StoreSectionInfo stores INIFile section information to section directory

Types

type INIEntry

type INIEntry struct {
	Section  string
	Key      string
	Operator Operator
	Value    string
}

INIEntry contains a single key-value pair in INI file.

type INIFile

type INIFile struct {
	AllValues []INIEntry
	KeyValue  map[string]map[string]INIEntry
}

INIFile contains all key-value pairs of an INI file.

func GetOverrides

func GetOverrides(filetype, ID string) (bool, *INIFile)

GetOverrides is looking for an override file and parse the content

func GetSectionInfo

func GetSectionInfo(initype, ID string, fileSelect bool) (*INIFile, error)

GetSectionInfo reads content of stored INIFile information. Return the content as INIFile

func ParseINI

func ParseINI(input string) *INIFile

ParseINI parse the content of the configuration file

func ParseINIFile

func ParseINIFile(fileName string, autoCreate bool) (*INIFile, error)

ParseINIFile read the content of the configuration file

type Operator

type Operator string

Operator is the comparison or assignment operator used in an INI file entry

type Sysconfig

type Sysconfig struct {
	AllValues []*SysconfigEntry // All key-value pairs in the orignal order.
	KeyValue  map[string]*SysconfigEntry
}

Sysconfig contains key-value pairs of a sysconfig file. It is able to convert back to original text in the original key order.

func ParseSysconfig

func ParseSysconfig(input string) (*Sysconfig, error)

ParseSysconfig read sysconfig text and parse the text into memory structures.

func ParseSysconfigFile

func ParseSysconfigFile(fileName string, autoCreate bool) (*Sysconfig, error)

ParseSysconfigFile read sysconfig file and parse the file content into memory structures.

func (*Sysconfig) GetBool

func (conf *Sysconfig) GetBool(key string, defaultValue bool) bool

GetBool return bool value that belongs to the key, or the default value if key does not exist. True values are "yes" or "true".

func (*Sysconfig) GetInt
