type Options = Marker | 'consistent'

Recommendation

Whether asterisks or underscores are used affects how and whether emphasis works. Underscores are sometimes used to represent normal underscores inside words, so there are extra rules in markdown to support that. Asterisks are not used in natural language, so they don’t need these rules, and thus can form emphasis in more cases. Asterisks can also be used as the marker of more constructs than underscores: lists. Due to having simpler parsing rules, looking more like syntax, and that they can be used for more constructs, it’s recommended to prefer asterisks.

Fix

remark-stringify formats strong with asterisks by default. Pass strong: '_' to always use underscores.

Examples

ok.md
In
**foo** and **bar**.
Out

No messages.

also-ok.md
In
__foo__ and __bar__.
Out

No messages.

ok.md

When configured with '*'.

In
**foo**.
Out

No messages.

ok.md

When configured with '_'.

In
__foo__.
Out

No messages.

not-ok.md
In
**foo** and __bar__.
Out
1:13-1:20: Strong should use `*` as a marker
not-ok.md

When configured with '💩'.

Out
1:1: Incorrect strong marker `💩`: use either `'consistent'`, `'*'`, or `'_'`

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, remark-lint-strong-marker@3, compatible with Node.js 12.
