Set-global-style-tag-registry

Replace the shared global StyleTagRegistry. This helper changes the default tag source used by formatters that do not define their own local registry.

Interface

pub fn set_global_style_tag_registry(registry : StyleTagRegistry) -> Unit {

input

• registry : StyleTagRegistry - New shared global registry value.

Explanation

Detailed rules explaining key parameters and behaviors

• This helper mutates process-wide shared formatter state.
• Only formatters without local style tags read from the global registry.
• It is useful for centralized theming or tests that need predictable tag behavior.

How to Use

Here are some specific examples provided.

When Need A Process-wide Custom Tag Default

When multiple formatters should share a custom default tag registry:

set_global_style_tag_registry(
  style_tag_registry().set_tag("accent", fg=Some("#102030"), dim=true),
)

In this example, subsequent formatters without local tag registries can resolve accent from the shared global registry.

Error Case

e.g.:

• If local formatter tags are already present, those local tags still take priority.

• Global mutation can affect later formatting broadly, so test code should usually restore or reset after temporary changes.

Notes

1. Use global_style_tag_registry() to snapshot the previous value before replacement.

2. Use reset_global_style_tag_registry() to restore the library default global registry.
