Instance Method Details

#convert(value, string_formats = :default) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Converts the given value to a String, under the direction of formatting rules per type.

When converting to string it is possible to use a set of built in conversion rules.

A format is specified on the form:

´´´ %[Flags][.Precision]Format ´´´

‘Width` is the number of characters into which the value should be fitted. This allocated space is padded if value is shorter. By default it is space padded, and the flag 0 will cause padding with 0 for numerical formats.

‘Precision` is the number of fractional digits to show for floating point, and the maximum characters included in a string format.

Note that all data type supports the formats ‘s` and `p` with the meaning “default to-string” and “default-programmatic to-string”.

### Integer

| Format | Integer Formats | —— | ————— | d | Decimal, negative values produces leading ‘-’ | x X | Hexadecimal in lower or upper case. Uses ..f/..F for negative values unless # is also used | o | Octal. Uses ..0 for negative values unless # is also used | b B | Binary with prefix ‘b’ or ‘B’. Uses ..1/..1 for negative values unless # is also used | c | numeric value representing a Unicode value, result is a one unicode character string, quoted if alternative flag # is used | s | same as d, or d in quotes if alternative flag # is used | p | same as d | eEfgGaA | converts integer to float and formats using the floating point rules

Defaults to ‘d`

### Float

| Format | Float formats | —— | ————- | f | floating point in non exponential notation | e E | exponential notation with ‘e’ or ‘E’ | g G | conditional exponential with ‘e’ or ‘E’ if exponent < -4 or >= the precision | a A | hexadecimal exponential form, using ‘x’/‘X’ as prefix and ‘p’/‘P’ before exponent | s | converted to string using format p, then applying string formatting rule, alternate form # quotes result | p | f format with minimum significant number of fractional digits, prec has no effect | dxXobBc | converts float to integer and formats using the integer rules

Defaults to ‘p`

### String

| Format | String | —— | —— | s | unquoted string, verbatim output of control chars | p | programmatic representation - strings are quoted, interior quotes and control chars are escaped

| C | each

name segment capitalized, quoted if alternative flag # is used

| c | capitalized string, quoted if alternative flag # is used | d | downcased string, quoted if alternative flag # is used | u | upcased string, quoted if alternative flag # is used | t | trims leading and trailing whitespace from the string, quoted if alternative flag # is used

Defaults to ‘s` at top level and `p` inside array or hash.

### Boolean

| Format | Boolean Formats | —- | ——————- | t T | ‘true’/‘false’ or ‘True’/‘False’ , first char if alternate form is used (i.e. ‘t’/‘f’ or ‘T’/‘F’). | y Y | ‘yes’/‘no’, ‘Yes’/‘No’, ‘y’/‘n’ or ‘Y’/‘N’ if alternative flag # is used | dxXobB | numeric value 0/1 in accordance with the given format which must be valid integer format | eEfgGaA | numeric value 0.0/1.0 in accordance with the given float format and flags | s | ‘true’ / ‘false’ | p | ‘true’ / ‘false’

### Regexp

| Format | Regexp Formats (%/) | —- | —————— | s | / / delimiters, alternate flag replaces / delimiters with quotes | p | / / delimiters

### Undef

| Format | Undef formats | —— | ————- | s | empty string, or quoted empty string if alternative flag # is used | p | ‘undef’, or quoted ‘“undef”’ if alternative flag # is used | n | ‘nil’, or ‘null’ if alternative flag # is used | dxXobB | ‘NaN’ | eEfgGaA | ‘NaN’ | v | ‘n/a’ | V | ‘N/A’ | u | ‘undef’, or ‘undefined’ if alternative # flag is used

### Default (value)

| Format | Default formats | —— | ————— | d D | ‘default’ or ‘Default’, alternative form # causes value to be quoted | s | same as d | p | same as d

### Binary (value)

| Format | Default formats | —— | ————— | s | binary as unquoted characters | p | ‘Binary(“<base64strict>”)’ | b | ‘<base64>’ - base64 string with newlines inserted | B | ‘<base64strict>’ - base64 strict string (without newlines inserted) | u | ‘<base64urlsafe>’ - base64 urlsafe string | t | ‘Binary’ - outputs the name of the type only | T | ‘BINARY’ - output the name of the type in all caps only

The alternate form flag ‘#` will quote the binary or base64 text output The width and precision values are applied to the text part only in `%p` format.

### Array & Tuple

| Format | Array/Tuple Formats | —— | ————- | a | formats with ‘[ ]` delimiters and `,`, alternate form `#` indents nested arrays/hashes | s | same as a | p | same as a

See “Flags” ‘<[({|` for formatting of delimiters, and “Additional parameters for containers; Array and Hash” for more information about options.

The alternate form flag ‘#` will cause indentation of nested array or hash containers. If width is also set it is taken as the maximum allowed length of a sequence of elements (not including delimiters). If this max length is exceeded, each element will be indented.

### Hash & Struct

| Format | Hash/Struct Formats | —— | ————- | h | formats with ‘{ }` delimiters, `,` element separator and ` => ` inner element separator unless overridden by flags | s | same as h | p | same as h | a | converts the hash to an array of [k,v] tuples and formats it using array rule(s)

See “Flags” ‘<[({|` for formatting of delimiters, and “Additional parameters for containers; Array and Hash” for more information about options.

The alternate form flag ‘#` will format each hash key/value entry indented on a separate line.

### Type

| Format | Array/Tuple Formats | —— | ————- | s | The same as p, quoted if alternative flag # is used | p | Outputs the type in string form as specified by the Puppet Language

### Flags

| Flag | Effect | —— | —— | (space) | space instead of + for numeric output (- is shown), for containers skips delimiters | # | alternate format; prefix 0x/0x, 0 (octal) and 0b/0B for binary, Floats force decimal ‘.’. For g/G keep trailing 0. | + | show sign +/- depending on value’s sign, changes x,X, o,b, B format to not use 2’s complement form | - | left justify the value in the given width | 0 | pad with 0 instead of space for widths larger than value | <[({| | defines an enclosing pair <> [] () {} or | | when used with a container type

### Additional parameters for containers; Array and Hash

For containers (Array and Hash), the format is specified by a hash where the following keys can be set:

  • ‘’format’‘ - the format specifier for the container itself

  • ‘’separator’‘ - the separator string to use between elements, should not contain padding space at the end

  • ‘’separator2’‘ - the separator string to use between association of hash entries key/value

  • ‘’string_formats’´ - a map of type to format for elements contained in the container

Note that the top level format applies to Array and Hash objects contained/nested in an Array or a Hash.

Given format mappings are merged with (default) formats and a format specified for a narrower type wins over a broader.

Parameters:

  • mode (String, Symbol) —

    :strict or :extended (or :default which is the same as :strict)

  • string_formats (String, Hash) (defaults to: :default) —

    format tring, or a hash mapping type to a format string, and for Array and Hash types map to hash of details

#puppet_quote(str, enforce_double_quotes = false) ⇒ String

Performs a ‘%p’ formatting of the given str such that the output conforms to Puppet syntax. An ascii string without control characters, dollar, single-qoute, or backslash, will be quoted using single quotes. All other strings will be quoted using double quotes.

Parameters:

  • str (String) —

    the string that should be formatted

  • enforce_double_quotes (Boolean) (defaults to: false) —

    if true the result will be double quoted (even if single quotes would be possible)

Returns:

  • (String) —

    the formatted string
