Description
Initial checklist
- I read the support docs
- I read the contributing guide
- I agree to follow the code of conduct
- I searched issues and couldn’t find anything (or linked relevant results below)
Affected packages and versions: nlcst-to-string >=2.0.4 (at least, maybe older too)
Steps to reproduce
If there are trailing whitespaces at the end of a line, it seems to get parsed as type: break in Markdown, which nlcst-to-string doesn't know how to convert to string.
Link to code example: https://codesandbox.io/s/remark-debug-forked-hh0ub?file=/src/index.js
Example AST subtree containing breaks:
[ { type: 'text',
value: 'Mobile: @6RpN4Ztw3jLwzQtHl8XpnnR58LWZTAjwq2vvfyx7zkc=.ed25519',
position:
{ start: { line: 3, column: 1, offset: 53 },
end: { line: 3, column: 62, offset: 114 },
indent: [] } },
{ type: 'break',
position:
{ start: { line: 3, column: 62, offset: 114 },
end: { line: 4, column: 1, offset: 117 },
indent: [ 1 ] } },
{ type: 'text',
value: 'Desktop: @lOUVT+Phkvai9a/cCS/RKo+S9hnPAQdVixms/7ldpPA=.ed25519',
position:
{ start: { line: 4, column: 1, offset: 117 },
end: { line: 4, column: 63, offset: 179 },
indent: [] } },
{ type: 'break',
position:
{ start: { line: 4, column: 63, offset: 179 },
end: { line: 5, column: 1, offset: 182 },
indent: [ 1 ] } },
{ type: 'text',
value: 'Pub: @5XaVcAJ5DklwuuIkjGz4lwm2rOnMHHovhNg7BFFnyJ8=.ed25519',
position:
{ start: { line: 5, column: 1, offset: 182 },
end: { line: 5, column: 59, offset: 240 },
indent: [] } } ]
Expected behavior
No crash or exception thrown in the JS engine. The stringification should complete and break nodes should be considered empty string.
Actual behavior
Uncaught JS exception:
[TypeError: Cannot read property 'length' of undefined]
