## Visor de axuda Yelp

### Introdución

The Yelp Help Browser application allows you to view documentation regarding GNOME and other components through a variety of formats. These formats include docbook files, HTML help pages, man pages and info pages (support for man pages and info pages may optionally be compiled in). Despite the different formats supported, Yelp does its best to provide a unified look and feel regardless of the original document format.

Yelp Help Browser is internationalised, meaning that it has support to view documents in different languages. The documents must be localised or translated for each language and installed properly for Yelp Help Browser to be able to view them.

#### Opening Specific Documents

##### Opening Documents from the File Manager

To open a document, such as an XML file, from the file manager, open the document in Nautilus File Manager, or drag the icon from Nautilus to the Yelp document pane or launcher.

##### Using the Command Line to Open Documents

Yelp Help Browser supports opening documents from the command line. There are a number of URIs (Uniform Resource Identifiers) that can be used. These include:

`file:`

  Use this URI when you want to access a file with yelp, for example:

      yelp file:///usr/share/gnome/help/gcalctool/C/gcalctool.xml

`ghelp:` or `gnome-help:`

  Use this URI when you want to access GNOME help documents, which are typically written in DocBook format.

      yelp ghelp:gcalctool

  If you want to open the help document at a particular section, append a question mark to the end of the URI, followed by the section id.

      yelp ghelp:user-guide?yelp-advanced-cmdline

`man:`

  Use this URI when you want to access a particular man page. You can append the section of the man page you would like to view if there are multiple man pages with the same name. The section number should be enclosed in parenthesis and therefore it may be necessary to escape the argument so that the shell does not interpret the parenthesis.

      yelp man:gcalctool

  or

      yelp 'man:intro(1)'
      yelp 'man:intro(2)'

`info:`

  Use this URI when you want to access a particular GNU info page.

      yelp info:make

#### Refreshing Content on Demand

Yelp Help Browser supports the Ctrl R shortcut keys, which will reload the DocBook document that is currently open. This allows developers to view changes to documents as they are made.

### More Information

This section details some of the helper applications which Yelp Help Browser uses, and provides resources where you can get more information about Yelp Help Browser.

#### Scrollkeeper

Yelp Help Browser uses scrollkeeper to generate the table of contents for DocBook and HTML documentation, and also keep track of translations for each document.

#### GNOME Documentation Utilites

The documentation distributed with GNOME uses this set of utilities for a variety of things:

- Ease translation of documents to different languages.

- Provide a set of tools to help package and install documentation into the correct location and register the documentation with scrollkeeper.

- Perform conversion from DocBook format to a format suitable for display.

Yelp Help Browser relies on GNOME XSLT Stylesheets to perform conversion from DocBook to HTML. GNOME Documentation Build Utilities are relied upon by application authors to install and register documentation within the help system.
