Proxmox VE Documentation
========================
-include::attributes.txt[]
We try to generate high quality documentation for
-http://www.proxmox.com[Proxmox VE], and choose to use
+{website}[{pve}], and choose to use
http://www.methods.co.nz/asciidoc/[AsciiDoc] as base format.
The basic idea is to generate high quality manual pages, and assemble
them into a complete book, called link:pve-admin-guide.adoc[Proxmox VE
Administration Guide]. So we have one source, and generate several
documents from that. It is also possible to generate printable PDF
-files, or ebook formats ('.ebup').
+files, or ebook formats ('.epub').
When possible, we provide scripts to extract API definitions,
configuration or command line options from the source code.
To simplify the documentation task, we keep all Documentation within
-this repository. It is possible to generate the docs (without installing
-any additional Proxmox packages) with:
+this repository. It is possible to generate the docs without installing
+any additional Proxmox packages with:
+ make pve-doc-generator.mk
make index
+To update the auto-generate API definitions use:
+
+ make update
+
+NOTE: you need a fully installed development environment for that.

Debian Packages
---------------
Another package called 'pve-docs' is used to publish generated
'.html' and '.pdf' files on our web servers. You can generate

-Common Macro definition in link:attributes.txt[]
-------------------------------------------------
+Common Macro definition in link:asciidoc/asciidoc-pve.conf[]
+------------------------------------------------------------
'asciidoc' allows us to define common macros, which can then be
referred to using `{macro}`. We try to use this mechanism to improve
consistency. For example, we defined a macro called `pve`, which
-expands to "Proxmox VE". The plan is to add more such definitions for
-terms which are used more than once.
+expands to "Proxmox VE".
+
+For URLs which are used more than once, two macros should be defined:
+
+* `{name-url}`, which just contains the http(s) URL
+* `{name}`, which contains the complete link including the canonical
+description
+
+For example, the macro `{forum-url}` expands to {forum-url}, and the macro
+`{forum}` expands to {forum}.
+
+The plan is to add more such definitions for terms which are used more
+than once.
+
+WARNING: When asciidoc encounters a misspelled macro name, it will
+silently drop the containing line!

development environment.
+Style Guide
+-----------
+
+'asciidoc' uses a fairly simple markup syntax for formatting content.
+The following basic principles should be followed throughout our
+documentation.
+
+
+Sections
+~~~~~~~~
+
+Sections are formatted using `two-line titles', by adding a line of
+the appropriate characters and of the same length as the section title
+below the title text:
+
+ Level 0 (top level): ======================
+ Level 1: ----------------------
+ Level 2: ~~~~~~~~~~~~~~~~~~~~~~
+ Level 3: ^^^^^^^^^^^^^^^^^^^^^^
+ Level 4 (bottom level): ++++++++++++++++++++++
+
+NOTE: Level 4 headings are currently not working for `manpage` outputs, you may
+want to use `.SECTION' instead, which results in the same rendering, and this
+level of Heading isn't displayed in any Index/TOC anyway.
+
+Section titles should always be preceded by two empty lines. Each word
+in a title should be capitalized except for ``articles, coordinating
+conjunctions, prepositions, and the word to in infinitives unless they
+appear as the first or last word of a title'' (see
+http://web.mit.edu/course/21/21.guide/capitals.htm[Mayfield Electronic Handbook of Technical & Scientific Writing]).
+
+
+Lists
+~~~~~
+
+Numbered Lists
+^^^^^^^^^^^^^^
+
+Numbered lists should be created using the implicit numbering format:
+
+-----
+. First level
+.. Second level
+. First level again
+-----
+
+. First level
+.. Second level
+. First level again
+
+
+Bulleted Lists
+^^^^^^^^^^^^^^
+
+Bulleted lists should be created using the '*' symbol:
+
+-----
+* First level
+** Second level
+* First level again
+-----
+
+* First level
+** Second level
+* First level again
+
+
+If you need to have other elements on the same level than a list element you
+can do this with the '+' symbol:
+
+----
+. First level
+.. Second level
++
+Anothe Sentence (or Block) on the continued second level.
+. First level again
+----
+
+. First level
+.. Second level
++
+Anothe Sentence (or Block) on the continued second level.
+
+. First level again
+
+Labeled Lists
+^^^^^^^^^^^^^
+
+Labeled lists should be used to make lists of key-value style text
+more readable, such as command line parameters or configuration options:
+
+.Regular labeled lists
+-----
+First Label Text::
+
+Element text paragraph
+
+Second Label Text::
+
+Another element text paragraph.
+-----
+
+First Label Text::
+
+Element text paragraph
+
+Second Label Text::
+
+Another element text paragraph.
+
+.Horizontal labeled lists
+-----
+[horizontal]
+First Label Text:: Element text paragraph
+
+Second Label Text:: Another element text paragraph.
+-----
+
+creates
+
+[horizontal]
+First Label Text:: Element text paragraph
+
+Second Label Text:: Another element text paragraph.
+
+The FAQ section uses a special questions and answers style for
+labeled lists.
+
+
+Text and Block Styles
+~~~~~~~~~~~~~~~~~~~~~
+
+'asciidoc' offers a wide range of default text styles:
+
+* 'Emphasized text': created using \'text', used for emphasizing words
+and phrases
+* `Monospaced text`: created using \`text`, used for command / program
+names, file paths, in-line commands, option names and values
+* *Strong text*: created using \*text*, used for emphasizing concepts
+or names when first introduced in a section.
+
+There are also different built-in block styles that are used in
+our documentation:
+
+Complete paragraphs can be included literally by prepending each
+of their lines with whitespace. Use this for formatting complete
+commands on their own line, such as:
+
+ pct set ID -option value
+
+----
+By surrounding a paragraph with lines containing at least four '-'
+characters, its content is formatted as listing.
+
+Use this for formatting file contents or command output.
+----
+
+Specially highlighted 'notes', 'warnings' and 'important' information
+can be created by starting a paragraph with `NOTE:`, `WARNING:` or
+`IMPORTANT:`:
+
+NOTE: this is a note
+
+WARNING: this is warning
+
+IMPORTANT: this is important information
+
+For each of these blocks (including lists and paragraphs), a block header
+can be defined by prepending the block with a `.' character and the header
+text:
+
+-----
+.Title of List
+* First element
+* Second element
+* Third element
+-----
+
+.Title of List
+* First element
+* Second element
+* Third element
+
+For example, block headers can be used to add file names/paths to file
+content listings.
+
+
+Online Help
+-----------
+Each {pve} installation contains the full documentation in HTML format,
+which is then used as the target of various help buttons in the GUI.
+
+If after adding a specific entry in the documentation you want to
+create a help button pointing to that, you need to do the
+following:
+
+* add a string id in double square brackets before your
+documentation entry, like `[[qm_general_settings]]`
+* rebuild the `asciidoc-pve` script and the HTML chapter file containing
+your entry
+* add a property `onlineHelp` in the ExtJS panel you want to document,
+using the above string, like `onlineHelp: qm_general_settings`
+This panel has to be a child class of PVE.panel.InputPanel
+
+On calling `make install` the asciidoc-pve script will populate
+a JS object associating the string id and a link to the
+local HTML documentation, and the help button of your input panel
+will point to this link.
+
+
+Screenshots
+-----------
+
+[thumbnail="screenshot/gui-datacenter-search.png"]
+
+First, it should be noted that we can display screenshots on 'html'
+and 'wiki' pages, and we can include them in printed documentation. But
+it is not possible to render them inside manual pages. So screenshot
+inside manual pages should be optional, i.e. the text should not
+depend on the visibility of the screenshot. You can include a
+screenshot by setting the 'thumbnail' attribute on a paragraph:
+
+----
+[thumbnail="screenshot/gui-datacenter-search.png"]
+First, it should be noted ...
+----
+
+The corresponding file need to reside inside folder
+`images/screenshot`, and should be in `.png` image format. We include
+the screenshots in printed documentation, and 'pdftex' uses the
+density (DPI) specified inside the file. So all screenshots should use
+the same density. We currently require the density set to 146 DPI, so
+that we can display a 1024 pixels wide image. You should not include
+larger screenshots (although it is possible).
+
+You can use the `./png-cleanup.pl` script to set the correct
+density. Simply use the following command to import a screenshot
+image:
+
+----
+# ./png-cleanup.pl screenshot.png images/screenshot/screenshot.png
+----
+
+TIP: You can use `identify -verbose screenshot.png` command to show
+all image attributes (from debian package 'imagemagick')
+
+.Default Screenshot Layout
+
+[thumbnail="screenshot/gui-datacenter-search.png"]
+
+We normally display screenshots as small thumbnail on the right side
+of a paragraph. On printed documentation, we render the full sized
+graphic just before the paragraph, or between the title and the text
+if the paragraph has a title. It is usually a good idea to add a title
+to paragraph with screenshots.
+
+[thumbnail="screenshot/gui-datacenter-search.png", float="left"]
+
+If you need to render many screenshots, it is possible to place them
+on the left side, so you can alternate the thumbnail position using the
+`float` attribute:
+
+----
+[thumbnail="screenshot/gui-datacenter-search.png", float="left"]
+If you need to render many screenshots ...
+----
+
+Please avoid to many consecutive screenshots to avoid rendering
+problems. Also verify the printed documentation to see if large
+screenshots create layout problems.
