TypeScript 7 is the native port: the package ships a `tsc` shim over a Go
binary, and `typescript` now exports `version` and `versionMajorMinor` and no
compiler API. Every `ts.createSourceFile` in scripts/ has been throwing
"Cannot read properties of undefined (reading 'Latest')" since the 5.9.3 → 7.0.2
bump -- four of the five i18n scripts dead, only i18n-extract still running.
Nothing noticed because no workflow runs them. The catalogue gate for nine
languages has been dark, and the only signal was running it by hand.
There is no official TS7 API package (@typescript/ast and @typescript/api are
both 404), and the alternative was rewriting 493 lines and 25 distinct AST
calls, including the JSX guards, against a different tree -- in tooling with no
tests of its own. So `typescript-ast` is an npm alias for the last TypeScript
carrying the JS API. It parses; `typescript` still type-checks and builds. Two
entries, two jobs, said so in each script so the next reader does not delete
one as a leftover.
What the gate says now it can speak: catalogues are green and coverage is 100%.
The "16 falling back to English" it reports in every locale are placeholders,
example domains, a product name, a licence id and the quote glyph -- strings
that should stay English. The 41 stale keys per locale are real dead weight and
are left for their own change.
The 143 the codemod refused turned out to be two different things, and only
one of them needed a person.
A third were phrases sitting next to an icon -- `<Plus /> New rule`. The
refusal rule was "has siblings", which is broader than the danger: what breaks
a translation is a sibling that renders *text*, splitting a sentence into
fragments no one can reorder. An element beside a phrase does not. Narrowing
the rule to text-producing siblings let the codemod take 73 more.
The rest were real sentences with values in the middle, rebuilt by hand as
named placeholders -- "Your active script “{name}” was written by hand",
"Waiting on the server — goes out {when}." Named rather than positional
because a translator moves the parts around; counted things go through
plural() so Russian and Ukrainian get their three forms rather than English's
two.
Sentences with an element inside them needed something new. `Open <code>mailto:
</code> links in ihasmail` has two obvious treatments and both are wrong:
splitting it into two t() calls hands over fragments that cannot be reordered,
and dropping the <code> keeps the sentence whole but loses the monospace that
said "this is a literal". tNode() keeps the sentence whole and makes the
element a named hole in it, so a translator sees one sentence and can put the
hole where their language wants it. The German test asserts exactly that: the
same call renders the code first when the catalogue says so.
The coverage number was also lying, and it is worth saying how. It counted
text inside <code> and inside translate="no" as untranslated work, and
placeholders like "123456" and "+1 555 0100" -- a one-time code and a phone
format. None of those will ever be translated, so the report sat at 21 with 6
real items left. A number with an unreachable floor is something to argue with
rather than act on, so the tool now applies the same rules the codemod does.
596 wrapped, nothing remaining. Verified in the browser across 15 views, which
is where the last bulk pass hid a bug the tests could not see: no entities, no
unfilled placeholders, no raw t( in rendered text, and the toggle switches that
looked like emptied labels are text-free by design.
Wrapping ~1,000 strings by hand is a thousand chances to mistype the copy
itself, and a parser does not get bored. scripts/i18n-extract.mjs does the
mechanical part -- JSX text and the attributes a person actually reads -- and
refuses the rest rather than guessing. 78% now: 515 wrapped, 143 left.
What it refuses matters as much as what it does. Text split around an
interpolation arrives as separate fragments, and wrapping each on its own
produces "Move " and " messages", which no translator can do anything with;
those are listed for a person to rebuild as sentences. So is anything
containing a double quote, which would end the literal.
Three things it had to be taught, each found by running it:
- <code>, <kbd> and <pre> are not prose. The first run wrapped `label:name`
inside <code> -- a search operator, where translating it breaks the thing it
documents. Subtrees marked translate="no" are skipped for the same reason.
- `t` is a natural name for a callback parameter and several files already use
it, so an import called `t` is shadowed inside those callbacks -- silently,
wherever the local happens to be callable. The name is checked per file now
and aliased to `translate` where it is taken.
- JSX decodes HTML entities and a JS string literal does not, so
`Language & region` moved into t("...") and rendered the entity on screen.
That last one is the one worth remembering. Typecheck passed, 443 tests
passed, and the page said "Language & region" in plain sight. It took
looking at a screenshot, and then a sweep of ten views to find the second
occurrence in a sentence I had written by hand earlier the same day. Nothing
in the toolchain was ever going to catch it: it is valid TypeScript rendering
valid text that happens to be wrong.
The codemod decodes entities now, and checks for a quote after decoding rather
than before.
