class cobbler.template_api.CobblerTemplate(**kwargs)[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. We don’t need to override __init__

SNIPPET(file: str)[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, **kwargs) → 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) → str | None[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:

AttributeError – Raised in case autoinstall_snippets_dir is missing.
FileNotFoundError – Raised in case some files are not found.

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.
