8.19. cobbler.templar module

Cobbler uses Cheetah templates for lots of stuff, but there’s some additional magic around that to deal with snippets/etc. (And it’s not spelled wrong!)

class cobbler.templar.Templar(api: CobblerAPI)[source]

Bases: object

Wrapper to encapsulate all logic of Cheetah vs. Jinja2. This also enables us to remove and add templating as desired via our self-defined API in this class.

check_for_invalid_imports(data: str) None[source]

Ensure that Cheetah code is not importing Python modules that may allow for advanced privileges by ensuring we whitelist the imports that we allow.

Parameters

data – The Cheetah code to check.

Raises

CX – Raised in case there could be a pontentially insecure import in the template.

render(data_input: Union[TextIO, str], search_table: Dict[Any, Any], out_path: Optional[str], template_type: str = 'default') str[source]

Render data_input back into a file.

Parameters
  • data_input – is either a str or a TextIO object.

  • search_table – is a dict of metadata keys and values.

  • out_path – Optional parameter which (if present), represents the target path to write the result into.

  • template_type – May currently be “cheetah” or “jinja2”. “default” looks in the settings.

Returns

The rendered template.

render_cheetah(raw_data: str, search_table: Dict[Any, Any]) str[source]

Render data_input back into a file.

Parameters
  • raw_data – Is the template code which is not rendered into the result.

  • search_table – is a dict of metadata keys and values (though results are always returned)

Returns

The rendered Cheetah Template.

Raises
  • SyntaxError – Raised in case the NFS paths has an invalid syntax.

  • CX – Raised in case there was an error when templating.

render_jinja2(raw_data: str, search_table: Dict[Any, Any]) str[source]

Render data_input back into a file.

8.20. cobbler.template_api module

Cobbler provides builtin methods for use in Cheetah templates. $SNIPPET is one such function and is now used to implement Cobbler’s SNIPPET:: syntax.

class cobbler.template_api.CobblerTemplate(**kwargs: Any)[source]

Bases: DynamicallyCompiledCheetahTemplate

This class will allow us to include any pure python builtin functions. It derives from the cheetah-compiled class above. This way, we can include both types (cheetah and pure python) of builtins in the same base template.

SNIPPET(file: str) Any[source]

Include the contents of the named snippet here. This is equivalent to the #include directive in Cheetah, except that it searches for system and profile specific snippets, and it includes the snippet’s namespace.

This may be a little frobby, but it’s really cool. This is a pure python portion of SNIPPET that appends the snippet’s searchList to the caller’s searchList. This makes any #defs within a given snippet available to the template that included the snippet.

Parameters

file – The snippet file to read and include in the template.

Returns

The updated template.

classmethod compile(*args: Any, **kwargs: Any) bytes[source]

Compile a cheetah template with Cobbler modifications. Modifications include SNIPPET:: syntax replacement and inclusion of Cobbler builtin methods. Please be aware that you cannot use the baseclass attribute of Cheetah anymore due to the fact that we are using it in our implementation to enable the Cheetah Macros.

Parameters
  • args – These just get passed right to Cheetah.

  • kwargs – We just execute our own preprocessors and remove them and let afterwards handle Cheetah the rest.

Returns

The compiled template.

read_snippet(file: str) Optional[str][source]

Locate the appropriate snippet for the current system and profile and read its contents.

This file could be located in a remote location.

This will first check for a per-system snippet, a per-profile snippet, a distro snippet, and a general snippet.

Parameters

file – The name of the file to read. Depending on the context this gets expanded automatically.

Returns

None (if the snippet file was not found) or the string with the read snippet.

Raises
sedesc(value: str) str[source]

Escape a string for use in sed.

This function is used by several cheetah methods in cheetah_macros. It can be used by the end user as well.

Example: Replace all instances of /etc/banner with a value stored in $new_banner

..code:

sed 's/$sedesc("/etc/banner")/$sedesc($new_banner)/'
Parameters

value – The phrase to escape.

Returns

The escaped phrase.

TODO

cobbler.template_api.read_macro_file(location: str = '/etc/cobbler/cheetah_macros') str[source]

TODO

Parameters

location – TODO

Returns

TODO
