anyconfig.backend.sh.variables

A simple backend module to load and dump files contain shell variables.

  • Format to support: Simple shell variables’ definitions w/o any shell variable expansions nor complex shell statements such as conditionals, etc.

  • Requirements: None (built-in)

  • Development Status :: 4 - Beta

  • Limitations: Currently, it only supports a varialbe defined in a line.

  • Special options: None

Changelog:

Added in version 0.7.0:

  • Added an experimental parser for simple shelll vars’ definitions w/o shell variable expansions nor complex shell statements like conditionals.

anyconfig.backend.sh.variables._parseline(line)

Parse a line contains shell variable definition.

Parameters:

line (str) – A string to parse, must not start with ‘#’ (comment)

Return type:

tuple[str | None, str | None]

Returns:

A tuple of (key, value), both key and value may be None

anyconfig.backend.sh.variables.load(stream, container=<class 'dict'>, **_kwargs)

Load shell variable definitions data from stream.

Parameters:

  • stream (IO) – A file or file like object

  • container (Callable[..., dict[str, Any]]) – Factory function to create a dict-like object to store properties

Return type:

dict[str, Any]

Returns:

Dict-like object holding shell variables’ definitions

class anyconfig.backend.sh.variables.Parser

Bases: StreamParser

Parser for Shell variable definition files.

_cid: ClassVar[str] = 'sh.variables'
_type: ClassVar[str] = 'shellvars'
_extensions: tuple[str, ...] = ('sh',)
_ordered: ClassVar[bool] = True
_dict_opts: tuple[str, ...] = ('ac_dict',)
load_from_stream(stream, container, **kwargs)

Load config from given file like object stream.

Parameters:

  • stream (IO) – A file or file like object of shell scripts define shell variables

  • container (Callable[..., dict[str, Any]]) – callble to make a container object

  • kwargs (Any) – optional keyword parameters (ignored)

Return type:

dict[str, Any]

Returns:

Dict-like object holding config parameters

dump_to_stream(cnf, stream, **_kwargs)

Dump config dat cnf to a file or file-like object stream.

Parameters:

  • cnf (Union[None, int, float, bool, str, dict[str, Any]]) – Shell variables data to dump

  • stream (IO) – Shell script file or file like object

  • kwargs – backend-specific optional keyword parameters :: dict

Return type:

None
