Este capítulo cobre a organização do processo de compilação da documentação e como o man:make[1] é usado para controlá-lo.

[[doc-build-rendering]]
== Renderizando AsciiDoc

Diferentes tipos de formato podem ser gerados a partir de um único arquivo AsciiDoc.

[cols="20%,20%,60%", frame="none", options="header"]
|===
| Formatos
| Tipo de Arquivo
| Descrição

|`html`
|HTML
|Um capítulo de `artigo` ou `livro`.

|`pdf`
|PDF
|Portable Document Format.

|`epub`
|EPUB
|Electronic Publication.
ePub file format.
|===

[[doc-build-rendering-html]]
=== Renderizando em html

Para renderizar a documentação e o site em `html`, use um dos seguintes exemplos.

[[documentation-build-example]]
.Compile a documentação
[example]
====
[source, shell]
....
% cd ~/doc/documentation
% make
....
====

[[website-build-example]]
.Compile o website
[example]
====
[source, shell]
....
% cd ~/doc/website
% make
....
====

[[project-build-example]]
.Compile todo o projeto de documentação
[example]
====
[source, shell]
....
% cd ~/doc
% make -j2
....
====

Exemplos avançados de compilação são apresentados abaixo:

[[documentation-build-example-verbose]]
.Compile a documentação com mensagens de debug e no modo verboso
[example]
====
[source, shell]
....
% cd ~/doc/documentation
% make HUGO_ARGS="--verbose --debug --path-warnings"
....
====

[[documentation-build-example-server]]
.Compile e sirva o conteúdo com o servidor web interno do Hugo
[example]
====
[source, shell]
....
% cd ~/doc/documentation
% make run
....
Este servidor web roda em `localhost`, porta`1313` por padrão.

Para servir o conteúdo com o servidor web interno do Hugo em um endereço IP específico:

[source, shell]
....
% make run BIND=192.168.15.10
....

Um `hostname` também pode ser definido como url base para o servidor web interno do Hugo:

[source, shell]
....
% make run BIND=192.168.15.10 HOSTNAME=example.com
....
====

[[doc-build-rendering-pdf]]
=== Renderizando em pdf

Para gerar a documentação em `pdf`, use um dos seguintes exemplos.

[[document-pdf-example]]
.Compilar todos os documentos em pdf
[example]
====
[source, shell]
....
% cd ~/doc/documentation
% make pdf
....
====

[[document-pdf-articles-example]]
.Compilar todos os artigos em pdf
[example]
====
[source, shell]
....
% cd ~/doc/documentation
% make pdf-articles
....
====

[[document-pdf-books-example]]
.Compilar todos os livros em pdf
[example]
====
[source, shell]
....
% cd ~/doc/documentation
% make pdf-books
....
====

[[document-pdf-language-example]]
.Compilar todos os documentos em pdf de um idioma em específico
[example]
====
[source, shell]
....
% cd ~/doc/documentation
% make DOC_LANG="en" pdf
....
Este comando irá compilar todos os documentos em pdf do idioma Inglês.

[source, shell]
....
% cd ~/doc/documentation
% make DOC_LANG="en fr" pdf-books
....
Este comando irá compilar todos os livros em pdf dos idiomas Inglês e Francês.
====

[[doc-build-toolset]]
== O Conjunto de Ferramentas de Compilação da Documentação do FreeBSD

Essas são as ferramentas usadas para compilar e instalar a documentação FDP.

* A principal ferramenta de compilação é o man:make[1], especificamente o Berkeley Make.
* Hugo
* AsciiDoctor
* Git

[[doc-build-makefile]]
== Compreendendo o Makefile na Árvore de Documentação

Existem três arquivos [.filename]#Makefile# para compilar em parte ou todo o projeto de documentação.

* O [.filename]#Makefile# no diretório [.filename]#documentation# irá compilar apenas a documentação.
* O [.filename]#Makefile# no diretório [.filename]#website# irá compilar apenas a website.
* O [.filename]#Makefile# na raíz irá compilar a documentação e o site.

O [.filename]#Makefile# dos subdiretórios também suportam `make run` para servir o conteúdo compilado com o servidor web interno do Hugo. Este servidor web roda na porta 1313 por padrão.

[[documentation-makefile]]
=== Makefile da Documentação

Este [.filename]#Makefile# suporta o seguinte:

[source, shell]
....
# Generate the FreeBSD documentation
#
# Copyright (c) 2020-2021, The FreeBSD Documentation Project
# Copyright (c) 2020-2021, Sergio Carlavilla <carlavilla@FreeBSD.org>
#
# Targets intended for use on the command line
#
# all (default)	-	generate the books TOC and compile all the documentation
# clean		- 	removes generated files
# run		-	serves the built documentation site for local browsing
# pdf		-	build PDF versions of the articles and books.
# html		-	build HTML versions of the articles and books for
#			offline use.
#			If variable DOC_HTML_ARCHIVE is set, all documents will be
#			archived/compressed, and only these files will be kept in the public
#			directory.
# epub		-	build EPUB versions of the articles and books (Experimental).
#
# The run target uses hugo's built-in webserver to make the documentation site
# available for local browsing.  The documentation should have been built prior
# to attempting to use the `run` target.  By default, hugo will start its
# webserver on port 1313.
