Building the Site for Local Preview

This repository includes a Gradle build script that you can use to build the documentation site for local preview. The script automates all aspects of the build. All you need on your machine to execute the build is a Java Development Kit (aka java and javac).

Begin by cloning the documentation repository:

$ git clone [email protected]:mulesoft/mulesoft-docs.git

💡	If you’re not interested in the entire history, and you want to reduce the size of the clone, add the --depth flag to execute a shallow clone: $ git clone --depth 1 [email protected]:mulesoft/mulesoft-docs.git

Next, switch to the directory into which you cloned the repository:

$ cd mulesoft-docs

Finally, use the gradlew command to launch Gradle and execute the site builder:

$ ./gradlew

Running gradlew with no arguments executes the default task, which is named build. It’s equivalent to the following:

$ ./gradlew build

(The build task may take several minutes to complete).

Once you’ve built the site, you can once again use Gradle to serve the site using a local, in-memory web server:

$ ./gradlew serve

You can now access the site from your browser at the location http://localhost:8000.

🔥	Currently, not all links work in the local preview since the preview server doesn’t implement the rewrite rules used in production. If you encounter a 404 when clicking on a link in the site navigation, try adding ".html" to the URL in the location bar.

When you want to stop the preview server, simply press Ctrl+c.

To run a full build and launch the preview server in one shot, combine the build and serve tasks:

$ ./gradlew build serve

Building a Single Page for Local Preview

As an alternative to building the entire site, the Gradle build provides a task named buildHtmlSingle to build a single page. The generated HTML page only includes the main content, styled to look similar to a page in the full site. However, the page does not include any of the site framing (header, footer, site navigation).

To build a single page, use the gradlew command to execute the buildHtmlSingle task. Specify the AsciiDoc document you want to build by passing the -Pfile=<path> flag:

$ ./gradlew buildHtmlSingle -Pfile=runtime-manager/v/latest/deploying-to-cloudhub.adoc

The HTML page will be generated into the _tmp directory. You can navigate to that file in your browser to preview it.

⚠️	Due to a bug in the single page docs builder, any images referenced by the page are copied to the wrong directory. You can workaround this bug by adding a symlink as follows: $ ln -s /tmp/_images _tmp/_images

Building the Site for Staging

The Gradle build script is also capable of building the site for staging and syncing the output to the staging server. The extra tasks and configuration needed for these operations are added when the profile property has the value staging. You can set this property by passing the flag -Pprofile=staging to the gradlew launch command.

To instruct Gradle to clean, build, and publish the staging site, execute the following command:

$ ./gradlew clean publish -Pprofile=staging

📎	The staging site combines the assets from the staging branch of mule-docs-site-assets with the content from the master branch of mule-docs.

Building the Site for Production

The Gradle build script is also capable of building the site for production and publishing it to git. The extra tasks and configuration needed for these operations are added when the profile property has the value prod. You can set this property by passing the flag -Pprofile=prod to the gradlew launch command.

To instruct Gradle to clean, build, and publish the production site, execute the following command:

$ ./gradlew clean publish -Pprofile=prod

🔥	The first time you execute this command, it will run for a very long time (depending on connection speed) since it must clone the publish (aka build output) repository anew.

💡	To prevent the publish task from pushing the new commit to the remote repository, pass the flag -PdryRun to the gradlew launch command.

AsciiDoc Conventions

• The width of a table is 100% by default, so only specify a width (as a percentage value) if you want it to be 95% or less.

• To specify the number of equal-width columns for a table, set the cols attribute to a number followed by an asterisk, such as [cols="3*"].

  🔥	The value of the cols attribute should never be a string of repeating commas (e.g., cols=",,,"). The only acceptable formats for the cols attribute value are (a) a single number followed by an asterisk (e.g., 3*) or (b) a comma-separated list of column specs (e.g., 1h,^2,>1).

• To allow the column widths of a table to be automatically sized by the browser to fit the contents, add the autowidth option, such as [%autowidth,cols="3*"].

  • By default, adding the autowidth option makes the width of the table only as wide as the browser needs it to be.

  • To force the width of a table with auto-width columns to span the whole page, add the spread role, such as [%autowidth.spread,cols="3*"].

    📎	Until further notice, the width attribute on a table is ignored when the autowidth option is used.

• To apply explicit relative widths to a table’s columns, set the cols attribute to a comma-separated list of ratio values, such as [cols="1,2,1"] (which resolves to [cols="25%,50%,25%"]).

  • The column width percentages are calculated with a precision of up to 4 decimal places.

• To apply a style to a column, add the letter corresponding to that style after the ratio value, such as [cols="1h,2,1"].

• Only apply the a style to a column if it has complex content, such as lists or source blocks. For example, [cols="1,1a"].

  • If an isolated table cell has complex content (and not the whole column), add the a style directly to the cell, such as a|content here.

• To give a table a header row, add the header option to the table, such as [%header,cols="3*"].

  • Option values are additive, so you can specify both the autowidth and header option using %header%autowidth.

  • A header row is implied if you put a blank line under the first row of the table in the AsciiDoc source.

• The shorthand syntax for options (e.g., %autowidth), roles (e.g., .spread), and IDs (e.g., #anchor) must always be placed in the first positional argument of the block attribute line, such as [%header%autowidth.spread,cols="3*"].

• Only add the source style to a listing block if you also specify a language (and want it to be syntax highlighted), such as [source,java].

• Omit linenums option on 1 line code examples.

• Put multi-word examples in a source block instead of a long tick marked string.

• Tab names should be "Visual Studio Editor" and "XML Editor or Standalone".

• Only XML or XML procedures can be in an XML tab. It’s illogical to put a screenshot in the XML tab.

• Restrict tables to 2 or 3 columns - multi-column tables can be very difficult to read.

• Wrap code example lines at spaces, or for Java after a dot. Code lines should be less than 60 characters, especially if you use the // <n> notation for callouts

• Until Coderay fixes the spacing for line numbers, don’t reference code examples by line numbers. Instead use // <n> in the code example and reference the notation in the text below the code example.

• Lists in the AsciiDoc source that use a bullet glyph (U+2022) as the marker are recognized as lists.

Lists

Rule	Description	Example
Imperative before lists	Before starting a list, provide a starting sentence that starts with "to" that describes the task you want people to provide. Also, don’t start a bullet or numbered list after a heading without a starting sentence.	To set the values:
Insert a period at the end of a sentence or bullet list item	Perform these tasks.	Perform these tasks
Start each item in a bullet list or numbered list with a capital letter	Start list items that are not reserved words with an init cap	Ensure all required fields are set.
Start number list items with an action	Number list items only start with an action such as Click, Set, etc.	Click the plus sign to the right of Connector Configuration.

Font Changes

Font	Description	Example
Bold	A button or field name	Click Test Connections.
tick marks	Reserved words or code examples, such as a MEL expression	#[payload]
Italics	Emphasis	Ensure the checkbox is set
Bold italics	Mule Enterprise license requirements.	Enterprise
Bold links	Important links like Skip to Code	*\<\<Skip to Code>>*

Headings

• No special characters in headings

• Init-cap each word in a heading

• Don’t put a colon at the end of a heading

• Ensure headings are in order, h1 > h2 > h3 > h4. Don’t skip levels such as h2 > h5

• Only one H1 per doc at the top of the file

• Don’t number headings

Word Choices

• JSON not Json

• POJO not pojo or Pojo

• MOJO not mojo or Mojo

• ID not id or Id

• Anypoint Studio not Mule Studio

Don’t spell out common acronyms such as POJO, JSON, MOJO, REST, SOAP, MQ, UI, IT, IP, TCP/IP
