Markdown cheatsheet

Markdown formatting is simple, and the CFEngine generator adds a few things to make it even simpler. Here's a list of the most commonly used formats.

Basic formatting

Remember

• "Always pull never push"

Basic formatting

One
Paragraph

Two
Paragraphs

One Paragraph

Two Paragraphs

**Bold** Bold

*Italic* Italic

Links

Link within documentation and to known pages

You can link to any documentation page using [linktext][PageTitle].

Link to a specific section of a known page

You can link to any documentation page section using [linktext][PageTitle#section].

When linking to a section, you should use the section name as it is rendered on the page.

For example, On the functions page we can link to the collecting functions section using [collecting functions][Functions#collecting functions].

Sometimes (because ¯\_(ツ)_/¯, maybe the page linked to hasn't been parsed yet) a page may not be automatically known. In this case an entry in _references.md.

Special characters in link targets

See generator/_scripts/cfdoc_linkresolver.py for how various characters are changed to dashes (--, ,:,.,(,)) and erased ("). Dashes are removed from the beginning and end of links as well.

Most (¯\_(ツ)_/¯) special characters are okay. For example:

• Link targets with / (forward slashes) work
  • [Export/import][Settings#Export/import] == Export/import

Anchors with underscores are problematic, may need to be escaped.

For example services_autorun in the MPF documentation the underscore needs to be escaped with a \.

**See also:** [`services_autorun` in the Masterfiles Policy Framework][Masterfiles Policy Framework#services\_autorun]

See also: [services_autorun in the Masterfiles Policy Framework][Masterfiles Policy Framework#services_autorun]

But not always! For example

**See also:** [cf_lock.lmdb][CFEngine directory structure#state/cf_lock.lmdb]

See also: cf_lock.lmdb

Backticks are problematic. It seems impossible to link to anchors that contain backticks.

Link to CFEngine keyword

The documentation pre-processor will create those automatically.

`classes` and `readfile()`

classes and readfile()

However, the preprocess will not create links if the code word is in triple backticks:

No links: ```classes``` and ```readfile()```

No links: classes and readfile()

Lists

Unordered lists - Markdown supports other markers than the asterisk, but in

CFEngine we use only *.

* Item 1
* Item 2
   * Item 2a
* Multi paragraph item

    Four spaces indented

• Item 1
• Item 2
  • Item 2a

• Multi paragraph item

  Four spaces indented

Ordered lists - the numbers you use don't matter.

1. first
1. second
9. Third

1. first
2. second
3. Third

Nested lists

* Item 1
  1. First
  2. First
    1. 1.2.1
* Item 2
  * Item 2a (2 spaces)

      I am indented 4 spaces

* Multi paragraph item

    I am indented four spaces

• Item 1
  1. First
  2. First
  3. 1.2.1

• Item 2

  • Item 2a (2 spaces)

    I am indented 4 spaces

• Multi paragraph item

  I am indented four spaces

Tables

Wiki-syntax for tables is supported, and you can be a bit sloppy about it, although it's better to align the | properly.

| Header | Left aligned | Centered | Right aligned |
|--------|:-------------|:--------:|--------------:|
|text    | text | X | 234 |

Code

Inline code

This renders as `inline code`.

This renders as inline code.

This also renders as ```inline code```.

This also renders as inline code.

See the note above on implicit linking - single backticks will link, triple backticks won't.

Code Blocks

Start a code block using triple backticks:

```
some code
in a block
```

some code
in a block

You can also create a code block by indenting your code by 4 spaces, however this does not support syntax highlighting and triple backticks are preferred.

To turn on syntax highlighting, specify the language ("brush") directly after the opening three backticks. Syntax highlighting is provided by pygments. Find all available lexers here.

Command code blocks

python3 -v

This code block will have command in the header and corresponding icon.

Command code block with output

To have a component that shows command, and it's output you need to place output code block following command one.

uname

Linux

You might also specify output syntax highlighting by adding language after the starting backticks and placing [output] in the first line. This line won't be shown in the resulted HTML.

curl --user admin:admin https://test.cfengine.com/api/user

{
  "meta": {
    "page": 1,
    "count": 1,
    "total": 1,
    "timestamp": 1350994249d
  },
  "data": [
    {
      "id": "calvin",
      "external": true,
      "roles": [
        "Huguenots", "Marketing"
      ]
    }
  ]
}

These two blocks will be joined into one element on the UI.

File code block

You can specify file name of the code block by adding [file=Name of the file] in the first line. This line won't be shown in the resulting HTML (it will be converted to the heading / frame).

bundle agent hello_world
{
  meta:
    "tags"
      slist => { "autorun" };
  vars:
    "github_path"
      string => "/tmp/github.com";
}

The resulting code block will show policy.cf as the filename.

CFEngine code blocks

If you want CFEngine syntax highlighting, use

```cf3
# CFEngine block

bundle agent example()
{
}
```

# CFEngine code block

bundle agent example()
{
}

Other frequently used syntax highlighters shown below.

Bash script code blocks

    ```bash
    #!/bin/bash
    echo hi
    for i in `seq 1 10`;
    do
      echo $i
    done
    ```

#!/bin/bash
echo hi
for i in `seq 1 10`;
do
  echo $i
done

Console blocks

    ```console
    root@policy_server # /etc/init.d/cfengine3 stop
    ```

root@policy_server # /etc/init.d/cfengine3 stop

SQL code blocks

    ```sql
    SELECT
         FileChanges.FileName,
         Count(Distinct(FileChanges.HostKey)) AS DistinctHostCount,
         COUNT(1) AS ChangeCount
      FROM
         FileChanges JOIN Contexts
      WHERE
         Contexts.ContextName='ubuntu'
      GROUP BY
         FileChanges.FileName
      ORDER BY
         ChangeCount DESC
    ```

  FROM
     FileChanges JOIN Contexts

     Contexts.ContextName='ubuntu'
  GROUP BY
     FileChanges.FileName

Code blocks and lists

If you want to include a code block within a list, put two tabs (8 spaces) in front of the entire block (4 to make the paragraph part of the list item, and 4 for it a code block):

* List item with code

        <code goes here>

• List item with code

  code

  <code goes here>
  

You can also use backticks (and get syntax highlighting) - just make sure the backticks are indented once:

1. First

    ```cf3
    # CFEngine block

    bundle agent example()
    {
    }
    ```

2. Second

Example policy from core

Examples from cfengine/core can be rendered using the CFEngine_include_example macro.

• Lines inside src starting with #@ are interpreted as markdown.

• Wrap macro in raw and endraw tags if the file contains mustache. This allows it to be rendered correctly.

  [\%CFEngine_include_example(class-automatic-canonificiation.cf)\%]

bundle agent main
{
  classes:

      "my-illegal-class";

  reports:

      # We search to see what class was defined:
      "$(with)" with => join( " ", classesmatching( "my.illegal.class" ) );

      # We see that the illegal class is explicitly not defined.
      "my-illegal-class is NOT defined (as expected, its invalid)"
        unless => "my-illegal-class";

      # We see the canonified form of the illegal class is defined.
      "my_illegal_class is defined"
        if => canonify("my-illegal-class");

      # Note, if takes expressisons, you couldn't do that if it were
      # automatically canonified. Here I canonify the string using with, and use
      # it as part of the expression which contains an invalid classcharacter, but
      # its desireable for constructing expressions.

      "Slice and dice using `with`"
        with => canonify( "my-illegal-class" ),
        if => "linux|$(with)";

}

First we promise to define my-illegal-class. When the promise is actuated it is automatically canonified and defined. This automatic canonification is logged in verbose logs (verbose: Class identifier 'my-illegal-class' contains illegal characters - canonifying). Next several reports prove which form of the class was defined. The last report shows how if takes a class expression, and if you are checking a class that contains invalid characters you must canonify it.

R: my_illegal_class
R: my-illegal-class is NOT defined (as expected, its invalid)
R: my_illegal_class is defined
R: Slice and dice using `with`

This policy can be found in /var/cfengine/share/doc/examples/class-automatic-canonificiation.cf and downloaded directly from github.

3.19.0:
    - Added interpreter attribute to standalone self upgrade package_module bodies
      (CFE-3703, ENT-5752)
    - Added almalinux as a know derivative of rhel (ENT-7644)
    - Added class to prevent hub from seeding binary packages for use in self upgrade
      (ENT-7544)
    - Added cleanup of database and status semaphore when federation target_state is off
      (ENT-7233)

    - Added script to cleanup artifacts after cfbs build (CFE-3781)
    - Added self upgrade support for SUSE (ENT-7446)
    - Added separate classes for controlling autorun inputs and bundles
      The class services_autorun continues to enable both automatic inclusion of .cf
      files in services/autorun and the running of bundles tagged with autorun.
      This change adds the classes services_autorun_inputs and
      services_autorun_bundles for independently enabling addition of .cf files in
      services/autorun and automatic execution of bundles tagged with autorun
      respectively.  (CFE-3715)
    - Added support for downloading community packages on hub in preparation for binary upgrades
    - Added variable for excluding files from Policy Analyzer (ENT-7684)
    - Adjusted badges for 3.18.0 release (ENT-6713)
    - Adjusted permissions for Mission Portal public tmp files (ENT-7261)
    - Autorun bundles now run regardless of locks
      Previously, when the autorun feature was enabled to automatically run bundles
      tagged with autorun the bundle actuation was affected by promise locking. The
      effect of this is that agent runs that happen close together would skip running
      bundles run within the last minute. Now autorun bundles no longer wait for a
      lock to expire, they will be actuated each agent execution. Note, promises
      within those bundles have their own locks which still apply.  (CFE-3795)
    - Dropped un-necessary local variable
      The use of this local variable triggers a bug that prevents datastate() from
      printing. Since the variable is un-necessary, it's been removed and the
      parameter is used directly.  (CFE-3776)
    - Enforced permissions for Postgres log (ENT-7961)
    - Fixed package module augments settings usage for pre 3.15.3 binaries
      (ENT-7356, ENT-7358)

      (ENT-7465)
    - Made apache restart more robust (ENT-8045)
    - Moved httpd.pid to root of httpd workdir (ENT-7966)
    - Physical Memory (MB) inventory now handles dmidecode MB or GB units
      (ENT-7714)
    - Promised permissions for Mission Portal application and Apache log files
      This change ensures that both Mission Portal and Apache log files have
      restrictive permissions. Previously this was un-managed.  (ENT-7730)
    - Reduced scope of report informing of missing systemd service
      (CFE-290, ENT-7360)
    - Removed build dir from install/dist targets (ENT-7359)

    - Set apache umask to 0177 (ENT-7948)
    - State changes of systemd services during agent run are now properly registered
      (CFE-3753)
    - Stopped enforcing permissions of modules in inputs
      This change removes explicit enforcement of permissions for modules in inputs.
      Instead of explicitly enforcing permissions in inputs, we rely on the default
      permissions (600). The previous explicit permissions (755) are un-necessary as
      modules are not executed from within the inputs directory and have resulted in
      permission flip-flopping in some environments. Permissions on modules in the
      modules dir (sys.workdir)/modules are still enforced.  (ENT-7733)
    - Switched from using package_method generic to default package_module
      for windows software inventory (ENT-2589)
    - Improved the reliability when detecting a Red Hat system.
      Now if the ID field in /etc/os-release is set to rhel, the redhat_pure class
      will be defined.
      If the variable sys.os_release does not exist, redhat_pure is defined if we have already
      defined redhat and we do not find classes for well known derivatives
    - rocky, a class defined on Rocky Linux was added to the list of well known derivatives
      (ENT-7628)
    - Added advisory lock for Federated Reporting operations (ENT-7474)
    - controls/cf_serverd.cf no longer specifies explicit
      default for bindtointerface and relies on the default
      binding to both :: and 0.0.0.0 on IPV6-enabled hosts
      (ENT-7362)
    - setup-status.json is no longer being repaired over and over on FR feeder hubs
      (ENT-7967)

3.18.0:
    - Added .ps1 to list of file patterns considered during policy update
      (ENT-4094)

    - Added inventory of users and hosts allowed to use cf-runagent
      (ENT-6666)
    - Added measurement of entropy available on linux systems (ENT-6495)
    - Added missing packages modules scripts in makefile (ENT-6814)
    - Added new interface for controlling users allowed to initiate cf-agent via cf-runagent
      (CFE-3544)
    - Added policy for permissions on cf-execd sockets on Enterprise Hubs
      (ENT-6777)
    - Added redirect to remove index.php from Mission Portal's URL
      (ENT-6464)
    - Added standalone self upgrade capability for Windows agents
      (ENT-6219, ENT-6823)
    - Added tail & tail_n to standard library (CFE-3558)
    - Added vars.mpf_admit_cf_runagent_shell to control admission for cf-runagent requests
      (ENT-6673)
    - Added verbose logfile for msiexec package module file installs
      (ENT-6220, ENT-6824)
    - Changed default behavior of policy update to keep inputs in sync with masterfiles
      Prior to this change, the default behavior of the MPF was to only ensure that
      files in masterfiles were up to date with the files in inputs. Files in inputs
      that did not exist in masterfiles were left undisturbed. To enable sync
      behavior (a common user expectation) you had to explicitly define
      'cfengine_internal_purge_policies'. Now, if you wish to return to the previous
      default behavior, define the class 'cfengine_internal_purge_policies_disabled'.
      Ticket: (CFE-3662)
    - Changed msiexec package module install logs to be unique for each msi file
      (ENT-6824)

    - standard_services now restarts the service if it was not already running
      when using service_policy => restart with chkconfig (Redmine #7258)

      days_older_than (Redmine #3009)

Including chunks of policy from the MPF

Here I am including a bundle named cfe_autorun_inventory_listening_ports. It may be a common or an agent bundle (in case the bundle ever changes types).

```cf3
bundle agent cfe_autorun_inventory_listening_ports
{
  vars:
      "ports" -> { "ENT-150" }
        slist => sort( "mon.listening_ports", "int"),
        meta => { "inventory", "attribute_name=Ports listening" },
        if => some("[0-9]+", "mon.listening_ports"),
        comment => "We only want to inventory the listening ports if we have
                    values that make sense.";
}
```

bundle agent cfe_autorun_inventory_listening_ports
{
  vars:
      "ports" -> { "ENT-150" }
        slist => sort( "mon.listening_ports", "int"),
        meta => { "inventory", "attribute_name=Ports listening" },
        if => some("[0-9]+", "mon.listening_ports"),
        comment => "We only want to inventory the listening ports if we have
                    values that make sense.";
}

Comments inside documentation

Sometimes it's nice to be able to put an internal comment into the documentation that will not be rendered.

You can use the comment and endcomment tags in markdown files.

For example:

{% comment %} TODO: We should try to improve this at some point.{% endcomment %}

Would render like this:

FAQ

When should I use verbatim vs bold or italic?

If it's code or something you would see on the command line (policy language, file names, command line options, binaries / CLI programs) use monospace (single backticks for inline, triple backticks for block, or when you have inline word that could also be an automatic link target that is undesirable, e.g. files (files) vs files (files) ).

If you are referring to something within UI / screenshots / buttons etc use bold and capitalize it as it is within the UI/Button/whatever.

      # attributes are not known in previous versions and must not be seen by
      # the parser or they will be seen as syntax errors. A cleaner way to do
      # this using the minimum_version macro is possible, but that would break
      # masterfiles compatibility in 3.12 with 3.7 binaries since 3.7 binaries
      # do not support major.minor.patch with minimum_version, only major.minor.

Variables

Referencing a version of CFEngine? Consider if that appearance should be updated with each new version.

Variables that are defined in the front matter (thats the content between the three dashes at the top) or in _config.yaml can be used directly within markdown.

For example this is the '3.24' version of the documentation. That variable comes from _config.yaml.

Since liquid variables look a lot like mustache variables any time you want to show the actual variables will need to be inside of raw tags.

site.CFE_manuals_version {{ site.CFE_manuals_version }}

Testing

Indention with included markdown

1. Verify that the selected hosts are upgrading successfully.

• Mission Portal Inventory reporting interface

• Inventory API

  code

   root@hub:~# curl -k \
   --user <admin>:<password> \
   -X POST \
   https://hub.localdomain/api/inventory  \
   -H 'content-type: application/json' \
   -d '{
         "sort":"Host name",
         "filter":{
            "CFEngine version":{
               "not_match":"3.24.0"
            }
         },
         "select":[
            "Host name",
            "CFEngine version"
          ]
       }'
