latch_cli.click_utils module#

class latch_cli.click_utils.EnumChoice(choices: Type[Enum], case_sensitive: bool = True)[source]#

Bases: Choice

convert(value: Any, param: Parameter | None, ctx: Context | None) → Any[source]#

Convert the value to the correct type. This is not called if the value is None (the missing value).

This must accept string values from the command line, as well as values that are already the correct type. It may also convert other compatible types.

The param and ctx arguments may be None in certain situations, such as when converting prompt input.

If the value cannot be converted, call fail() with a descriptive message.

Parameters:

  • value – The value to convert.

  • param – The parameter that is using this type to convert its value. May be None.

  • ctx – The current context that arrived at this value. May be None.

class latch_cli.click_utils.ColoredHelpFormatter(indent_increment: int = 2, width: int | None = None, max_width: int | None = None)[source]#

Bases: HelpFormatter

write_usage(prog: str, args: str = '', prefix: str | None = None) → None[source]#

Writes a usage line into the buffer.

Parameters:

  • prog – the program name.

  • args – whitespace separated list of arguments.

  • prefix – The prefix for the first line. Defaults to "Usage: ".

write_heading(heading: str)[source]#

Writes a heading into the buffer.

write_dl(rows: Sequence[Tuple[str, str]], col_max: int = 30, col_spacing: int = 2) → None[source]#

Writes a definition list into the buffer. This is how options and commands are usually formatted.

Parameters:

  • rows – a list of two item tuples for the terms and values.

  • col_max – the maximum width of the first column.

  • col_spacing – the number of spaces between the first and second column.
