Recommendation
Whether asterisks or underscores are used affects how and whether strong
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 strong 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-asterisk.md
When configured with '*'.
In
**Mercury**.
Out
No messages.
not-ok-asterisk.md
When configured with '*'.
In
__Mercury__.
Out
1:1-1:12: Unexpected strong marker `_`, expected `*`
ok-underscore.md
When configured with '_'.
In
__Mercury__.
Out
No messages.
not-ok-underscore.md
When configured with '_'.
In
**Mercury**.
Out
1:1-1:12: Unexpected strong marker `*`, expected `_`
not-ok-consistent.md
In
**Mercury** and __Venus__.
Out
1:17-1:26: Unexpected strong marker `_`, expected `*`
not-ok.md
When configured with '🌍'.
Out
1:1: Unexpected value `🌍` for `options`, expected `'*'`, `'_'`, or `'consistent'`
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@4,
compatible with Node.js 16.
