Library.info

Here is a generic library.info configuration file:

[Library]
name = ""
library_version = 1
host_version = 1
l10n = false
locale = 
category = ""
category_icon = 
category_class = 
subcategory = ""
bundle_class = 

General Notes

.info files follow a key/value pair format, similar to the fd.o desktop entry spec

Entries

Entries in the file are {key,value} pairs in the format: Key = Value

Space before and after the equals sign is ignored; the = sign is the actual delimiter.

Value Types

The value types recognized are string, boolean, and numeric.

Values of type string may contain all ASCII characters except for control characters (space, newline, tab, carriage return, etc.). To include any of these characters, use the appropriate escape sequence. Strings should be delimited by double quotation marks, e.g. "This is a string".

Values of type boolean must either be true or false.

Values of type numeric must be a valid floating point number, e.g. 13 or -2.5.

Multiple Values

Some keys can have multiple values. In such a case, the value of the key is specified as a plural: for example, locales. The multiple values should each be separated by a semicolon. Those keys which have several values should have a semicolon as the trailing character. Semicolons in these values need to be escaped using \;.

Keys/Values

[Library] (required)

The library.info file must begin with [Library], and only that, on the first line of the file.

name (required)

This entry is the name is displayed in the library navigation sidebar that refers to the collection. Visit the online version of the OLPC Library to view the current navigation sidebar and categories.

library_version (required)

The version is a single positive integer that refers to the version of the collection. Larger numbers are considered "newer". For now, the version is 1.

host_version (required)

The host version is a single positive integer that refers to the version of Sugar which the collection is compatible with. For now, the version is 1.

l10n (required)

This entry indicates whether the bundle is "officially" localized. The value is either true or false.

Note: What it means to be "officially" localized hasn't been entirely worked out yet, so the value of this entry is always false for now.

locale (required)

This is the ISO code for the language of the collection, in lowercase, followed by an underscore, and then its localization information (also represented in ISO code). In this case, US-localized English is represented as en_US. UK-localized English, for example, would be represented as en_UK.

In the case of collections that are "unofficially" localized and/or contain content in multiple languages, you can indicate multiple locales. An example would be:

locales = en_US;en_UK;es_PE;es_AR;

Note that locales is pluralized in order to indicate multiple values. Note also that values are separated by semi-colons, and that the final value must end with a semi-colon as well.

category (required)

This refers to the category classification in the OLPC Library (visible on navigation sidebar). See the category chart below for current options. As always, if you don't like what you see, you can add your own.

category_icon (optional)

This is the filename of the icon that represents the collection in the library navigation sidebar. The actual image file is stored in the library directory (see configuration files. This entry is only required if you decide to place your collection in a new top-level category in the library navigation sidebar. Otherwise, the pre-defined category icon is used.

category_class (optional)

This entry refers to the category's CSS class. This is required if you decide to place your bundle into a new top-level category. Otherwise, the default class for the category is used. See the category chart below for current categories and related classes.

subcategory (optional)

This refers to the subcategory classification within a category (visible on the navigation sidebar). If no subcategory is provided, the collection will be placed in its own subcategory. See category chart for current options. Again, and as always, if you don't like what you see, you can add your own.

bundle_class (optional)

This entry is required if the collection is using a customized library.css file. The bundle_class value should be the same name as the collection's .xol file, except in lower case (and without the ".xol"). No whitespace or special characters are allowed. Otherwise, the category class is used.
