Types ¶

type Opt ¶

type Opt func(*StringTemplate) error

func Function ¶

func Function(name string, f interface{}) Opt

Function allows the user to specify functions for use in the template. If the name provided is a function that already exists in the function map, this will override the previously specified function.

func Template ¶

func Template(rawTemplate string) Opt

type StringTemplate ¶

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

StringTemplate creates strings based on the provided template. This uses the go templating language, so anything that adheres to that language will function in this struct. There are several custom functions available for use in the template: - random

• Randomly generated characters. This uses the charset specified in RandomCharset. Must include a length. Example: {{ rand 20 }}

- truncate

• Truncates the previous value to the specified length. Must include a maximum length. Example: {{ .DisplayName | truncate 10 }}

- truncate_sha256

• Truncates the previous value to the specified length. If the original length is greater than the length specified, the remaining characters will be sha256 hashed and appended to the end. The hash will be only the first 8 characters The maximum length will be no longer than the length specified. Example: {{ .DisplayName | truncate_sha256 30 }}

- uppercase

• Uppercases the previous value. Example: {{ .RoleName | uppercase }}

- lowercase

• Lowercases the previous value. Example: {{ .DisplayName | lowercase }}

- replace

• Performs a string find & replace Example: {{ .DisplayName | replace - _ }}

- sha256

• SHA256 hashes the previous value. Example: {{ .DisplayName | sha256 }}

- base64

• base64 encodes the previous value. Example: {{ .DisplayName | base64 }}

- unix_time

• Provides the current unix time in seconds. Example: {{ unix_time }}

- unix_time_millis

• Provides the current unix time in milliseconds. Example: {{ unix_time_millis }}

- timestamp

• Provides the current time. Must include a standard Go format string

- uuid

• Generates a UUID Example: {{ uuid }}

func NewTemplate ¶

func NewTemplate(opts ...Opt) (up StringTemplate, err error)

NewTemplate creates a StringTemplate. No arguments are required as this has reasonable defaults for all values. The default template is specified in the DefaultTemplate constant.

func (StringTemplate) Generate ¶

func (up StringTemplate) Generate(data interface{}) (string, error)

Generate based on the provided template
