dash

A house-style rule, off until a decisions table turns it on: it reports an em dash, an en dash or a spaced double hyphen in prose.

What it catches

An em dash, an en dash or a spaced double hyphen in prose.

Dimension

conventions: a house or genre convention is broken. A finding is counted on the dimension of its rule, the cost it names to the reader.

Why

House style: plain-ASCII typography is one repository's policy, ported from its Buzz lint so proofread alone reproduces it. Off unless a decisions table turns it on.

Default decision

The code is PRF5002. The decision depends on the kind of text judged:

House style ships off: the rule encodes one repository's conventions, not a rule of plain writing. A repository turns it on in its decisions table.

Changing it

A decisions table sets this rule to deny, advise or off, for everything judged or for the files a glob matches. Proofread reads the table from the file its -decisions flag names:

{
  "rules": {"dash": "deny"},
  "paths": {"blog/**": {"dash": "off"}}
}

rules applies to every file. A glob in paths applies to the files it matches, and the last match wins. A rule set to off never reports.

Seeing it

A finding names the rule, its code and the decision that applies, and links here:

{"rule": "dash", "code": "PRF5002", "decision": "deny", "url": "https://eli.gladman.cc/magus/reference/proofread/dash/"}

proofread rules prints this entry with every other rule's.
