import remarkLintFencedCodeMarker from 'remark-lint-fenced-code-marker'
import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import {read} from 'to-vfile'

API
This package exports no identifiers.
It exports the TypeScript types
Marker and
Options.
The default export is
remarkLintFencedCodeMarker.
unified().use(remarkLintFencedCodeMarker[, options])
Warn when fenced code markers are inconsistent.
Parameters
options(Options, default:'consistent')
— preferred style or whether to detect the first style and warn for
further differences
Returns
Transform (Transformer from unified).
Marker
Marker (TypeScript type).
Type
type Marker = '`' | '~'
Options
Configuration (TypeScript type).
Type
type Options = Marker | 'consistent'
Recommendation
Tildes are uncommon.
So it’s recommended to configure this rule with '`'.
Fix
remark-stringify formats fenced code with grave
accents by default.
Pass fence: '~' to always use tildes.
Examples
ok-indented.md
In
Indented code blocks are not affected by this rule:
mercury()
Out
No messages.

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-fenced-code-marker@4,
compatible with Node.js 16.
