Minimal color scheme

This package has the option to choose a more minimal color scheme.

The aim is to create admonitions that are clearly different to the core text with colors that do not over emphasises the admonition such as

compared to the current default

To enable the minimal color scheme you can use the following.

Jupyter Book Project

Add proof_minimal_theme = True to your _config.yml

sphinx:
  config:
    proof_minimal_theme: true

Sphinx Project

Add proof_minimal_theme = True to your conf.py

Shared numbering

By default, each type of (prf-)directive has their own numbering and counter. This can be changed by setting the option prf_realtyp_to_countertyp to a dictionary associating to a directive which the counter of which directive it should use.

Sphinx Project

In conf.py, e.g. to have a shared counter for all directives:

prf_realtyp_to_countertyp = {
    "axiom": "theorem",
    "theorem": "theorem",
    "lemma": "theorem",
    "algorithm": "theorem",
    "definition": "theorem",
    "remark": "theorem",
    "conjecture": "theorem",
    "corollary": "theorem",
    "criterion": "theorem",
    "example": "theorem",
    "property": "theorem",
    "observation": "theorem",
    "proposition": "theorem",
    "assumption": "theorem",
    "notation": "theorem",
}

In the following case, the directives lemma, conjecture, corollary and proposition will share the counter with theorem, while axiom and assumption will share the counter with definition. All other directives would use their original counter.

prf_realtyp_to_countertyp = {
    "lemma": "theorem",
    "conjecture": "theorem",
    "corollary": "theorem",
    "proposition": "theorem",
    "axiom": "definition",
    "assumption": "definition",
}

Warning

The association of a counter to a directive is not transitive: Let us consider the following configuration:

prf_realtyp_to_countertyp = {
    "lemma": "theorem",
    "conjecture": "lemma",
}

The lemma and theorem directives share a counter, however the conjecture directive has a separate counter (the lemma counter which is not used by lemma directives).

Title format

By default, the directive titles are formatted as Name x.y.z (Title), where Name is the name of the directive (e.g., Proof, Theorem, Definition), x.y.z is the numbering of the directive, and Title is the optional title provided by the user.

If no title is provided, only Name x.y.z is displayed.

The font weight of the entire title (Name x.y.z (Title) or Name x.y.z) is set to --pst-admonition-font-weight-heading by default, which commonly results in a semi-bold appearance.

In the reminder we call the part Name x.y.z the “number” and the part (Title) the “title”.

You can customize the title format using the proof_title_format option:

• This option allows you to define how the title should be displayed by using %t as a placeholder for the user-provided title.

• The default format is (%t).

• A value of an empty string will result in no title being displayed.

• A markdown string can be used to format the title.

  • For example, *%t* will emphasize the title and contain no brackets.

Note that the initial part of the title (i.e., Name x.y.z) is not customizable and will always be displayed.

The font weight of the title can be adjusted using the proof_title_weight option:

• Any valid CSS font-weight value can be used, such as normal, bold, bolder, lighter, or numeric values like 400, 700, etc.

• Default value is var(--pst-admonition-font-weight-heading).

The font weight of the number can be adjusted using the proof_number_weight option:

• Any valid CSS font-weight value can be used, such as normal, bold, bolder, lighter, or numeric values like 400, 700, etc.

• Default value is var(--pst-admonition-font-weight-heading).
