Naming Templates

File and Folder names can be customized using Libation's built-in tag template naming engine. To edit how folder and file names are created, go to Settings > Download/Decrypt and edit the naming templates. If you're splitting your audiobook into multiple files by chapter, you can also use a custom template to set each chapter's title metadata tag by editing the template in Settings > Audio File Options.

These templates apply to both GUI and CLI.

Template Tags

These are the naming template tags currently supported by Libation.

Property Tags

These tags will be replaced in the template with the audiobook's values.

To change how these properties are displayed, read about custom formatters

Conditional Tags

Anything between the opening tag (<tagname->) and closing tag (<-tagname>) will only appear in the name if the condition evaluates to true.

Tag	Description	Type
<if series->...<-if series>	Only include if part of a book series or podcast	Conditional
<if podcast->...<-if podcast>	Only include if part of a podcast	Conditional
<if bookseries->...<-if bookseries>	Only include if part of a book series	Conditional
<if podcastparent->...<-if podcastparent> †	Only include if item is a podcast series parent	Conditional
<if abridged->...<-if abridged>	Only include if item is abridged	Conditional
<has PROPERTY->...<-has>	Only include if the PROPERTY has a value (i.e. not null or empty)	Conditional
<is PROPERTY[CHECK]->...<-is>	Only include if the PROPERTY or a single value of a list PROPERTY satisfies the CHECK	Conditional
<is PROPERTY[FORMAT][CHECK]->...<-is>	Only include if the formatted PROPERTY or a single value of a list PROPERTY satisfies the CHECK	Conditional
<is PROPERTY[...separator(...)...][CHECK]->...<-is>	Only include if the joined form of all formatted values of a list PROPERTY satisfies the CHECK	Conditional
<cmp 1st-PROPERTY [CHECK] 2nd-PROPERTY->...<-cmp>	Only include if two given PROPERTIES satisfy the CHECK	Conditional

† Only affects the podcast series folder naming if "Save all podcast episodes to the series parent folder" option is checked.

For example, <if podcast-><series><-if podcast> will evaluate to the podcast's series name if the file is a podcast. For audiobooks that are not podcasts, that tag will be blank.

You can invert the condition (instead of displaying the text when the condition is true, display the text when it is false) by playing a ! symbol before the opening tag name.

Inverted Tag	Description	Type
<!if series->...<-if series>	Only include if not part of a book series or podcast	Conditional
<!if podcast->...<-if podcast>	Only include if not part of a podcast	Conditional
<!if bookseries->...<-if bookseries>	Only include if not part of a book series	Conditional
<!if podcastparent->...<-if podcastparent> †	Only include if item is not a podcast series parent	Conditional
<!has PROPERTY->...<-has>	Only include if the PROPERTY does not have a value (i.e. is null or empty)	Conditional
<!is PROPERTY[CHECK]->...<-is>	Only include if neither the whole PROPERTY nor the values of a list PROPERTY satisfies the CHECK	Conditional
<!cmp 1st-PROPERTY [CHECK] 2nd-PROPERTY->...<-cmp>	Only include if two given PROPERTIES do not satisfy the CHECK	Conditional

† Only affects the podcast series folder naming if "Save all podcast episodes to the series parent folder" option is checked.

As an example, this folder template will place all Liberated podcasts into a "Podcasts" folder and all liberated books (not podcasts) into a "Books" folder.

<if podcast->Podcasts<-if podcast><!if podcast->Books<-if podcast><title>

This example will add a number if the <series#> tag has a value:

<has series#><series#><-has>

This example will put non-series books in a "Standalones" folder:

<!if series->Standalones/<-if series>

And this example will customize the title based on whether the book has a subtitle:

<audible title><has audible subtitle->-<audible subtitle><-has>

Tag Formatters

Text, Name, Series, Number, TimeSpan, DateTime, Region, Language and their List tags can be optionally formatted using format text in square brackets after the tag name. Below is a list of supported formatters for each tag type.

Text Formatters

Text formatting can change length and case of the text. Use <#>, <#><case> or <case> to specify one or both of these.

Formatter	Description	Example Usage	Example Result
#	Cuts down the text to the specified number of characters	<title[14]>	A Study in Scar
L	Converts text to lowercase	<title[L]>	a study in scarlet꞉ a sherlock holmes novel
U	Converts text to uppercase	<title short[U]>	A STUDY IN SCARLET
t	Converts text to title case	<title[t]>	The Abc Murders

TimeSpan Formatters

For more custom formatters and examples, see this guide from Microsoft.

Formatter	Description	Example Usage	Example Result
d	The "d" custom format specifier outputs the value of the TimeSpan.Days property, which represents the number of whole days in the time interval. It outputs the full number of days in a TimeSpan value, even if the value has more than one digit. If the value of the TimeSpan.Days property is zero, the specifier outputs "0".

Use "dd"-"dddddddd" for zero padding up to the specified size. | <minutes[dd]> | 02 | | h | The "h" custom format specifier outputs the value of the TimeSpan.Hours property, which represents the number of whole hours in the time interval that isn't counted as part of its day component. It returns a one-digit string value if the value of the TimeSpan.Hours property is 0 through 9, and it returns a two-digit string value if the value of the TimeSpan.Hours property ranges from 10 to 23.

Use "hh" for zero padding. | <minutes[hh]> | 14 | | m | The "m" custom format specifier outputs the value of the TimeSpan.Minutes property, which represents the number of whole minutes in the time interval that isn't counted as part of its day component. It returns a one-digit string value if the value of the TimeSpan.Minutes property is 0 through 9, and it returns a two-digit string value if the value of the TimeSpan.Minutes property ranges from 10 to 59.

Use "mm" for zero padding. | <minutes[m]> | 42 | | 'string' | Literal string delimiter. | <minutes[d'd 'h'h 'm'm']> | 2d 14h 42m | | \ | The escape character. | <minutes[d\d h\h m\m]> | 2d 14h 42m |

These formatters have been enhanced to allow the display of days, hours or months beyond their usual limits. For example, the total number of hours, even if it exceeds 23. Here, a number format is inserted for the desired part in accordance with Microsoft's instructions. Unlike standard number formats, however, the letters D, H or M (uppercase) are used instead of zeros.

Formatter	Description	Example Usage	Example Result
D	A number format with "D" instead of "0". Using this will output the total number of days and reduce the amount of minutes avalable for "H" and "M".	<minutes[DD]>	02
H	A number format with "H" instead of "0". Using this will output the total number of hours and reduce the amount of minutes available for "M".	<minutes[HH]>	62
M	A number format with "M" instead of "0". Using this will output the total number of minutes.	<minutes[#,#MM]>	3,762
D H M	A combination of the above.	<minutes[D'days 'MM'minutes']>	02days 882minutes

† For further information on format templates, please refer to the Format templates section.

‡ LANG may be any code from the ISO 639-1 standard like es for Spanish, en for English, de for German, etc. or even a IETF language tag like 'fr-CA'.

Format Templates

Depending on which property is to be displayed, one or more placeholders can be used in a format template. The placeholders are defined in the form {A}:

<first author[{F} {U}]>

The format template must sometimes be enclosed in square brackets and sometimes in round brackets. In addition to placeholders, the format template may also contain arbitrary text. To prevent this text from being mistaken for a bracket at the end of the template or a placeholder, escapes can be used within the text:

• \x - Escapes the next character.
• \\ - Escapes a backslash.
• "text" - encloses text that may contain special characters. To include a double quote in the text, escape it by doubling it: "She said ""Hello""" will output She said "Hello".
• 'text'- encloses text that may contain special characters. To include a single quote in the text, escape it by doubling it: 'It''s a test' will output It's a test.

<series[separator(,) format('{Series:' {N}\})]>

Not all elements of a property are always present or have content. In this case, format templates would contain gaps after substitution. Groups of spaces are automatically merged. Other characters, however, remain unchanged. By doubling the curly brackets, you can specify text fragments before and after the placeholder, which are only used if the placeholder is replaced with content.

<!-- VitePress compiles each .md as a Vue SFC: a literal `{{` inside normal backtick `code` is treated as Vue interpolation and breaks the build. Elsewhere this doc uses backticks for inline examples; this line is HTML `code` with `v-pre` so `{{` can be written literally and still render like the other snippets, without additional hacks such as obscure invisible characters (like &#200B : 0-width space). -->

<code v-pre><narrator[format({{F} }{({M}') '}{L})]></code> -> <code>Neil Gaiman, Christopher (Evan) Welch</code>

Checks

There are two formats for checks, with slightly different syntax for specifying parameters:

<is PROPERTY[CHECK-with-value]->...<-is>

<cmp 1st-PROPERTY CHECK 2nd-PROPERTY->...<-cmp>

For CHECK-with-value, the value (2nd parameter) is specified directly after the check operator (e.g., =). This may be a number or a string with escaped characters like \]. Single backslashes must be doubled if they are part of the string.

1st-PROPERTY and 2nd-PROPERTY may be any of the properties listed in the Property tags section, or they may be string or number literals. Use digits only for numbers. To specify a string literal, enclose it in single or double quotes. If the string contains a single or double quote, escape it by doubling it. For example, to specify the string literal O'Reilly, you can use either 'O''Reilly' or "O'Reilly".

String Checks	Unicode Operator	Description	Examples
=		Matches if values are equal (case-insensitive)	<is tag[=Tag1]->
!=		Matches if values are not equal (case-insensitive)	<is first author[!=Arthur]->
<cmp "foo" != 'bar'->
~		Matches if the first parameter matches the regular expression specified by the second parameter (case-insensitive)	<is title[~([XYZ]).*\1]->

Number Checks	Unicode Operator	Description	Examples
#= †		Matches if the number value equals NUMBER	<is channels[#=2]->
<cmp channels #= 1->
#!= †	≠	Matches if the number value does not equal NUMBER	<is author[#!=1]->
#>= †	≥	Matches if the number value is greater than or equal to NUMBER	<is bitrate[#>=128]->

>-> | :proper_superset:	⊃	Matches if the first parameter contains all elements from the second parameter plus at least one additional element	<cmp author ⊃ narrator->

† NUMBER checks on lists check the size of the list. For string values, the string length is used.

More Complex Examples

This example truncates the title to 4 characters and checks if its (trimmed) value equals "the" (case-insensitive):

<is title[4][=the]>

This example takes tags 2 through 4, joins them with a colon, and checks if the result equals "Tag2:Tag3:Tag4":

<is tag[separator(:)slice(2..4)][=Tag2:Tag3:Tag4]->
