Issue #4390: imported Chinese web-novels showed author either **missing (未知)** or
|
||
as an **irrelevant metadata blob** (e.g. `2024/08/01发表于：是否首发：是字数1023150字116:01`).
|
||
|
||
**Key debugging tell:** the displayed *title* was the **entire filename** including
|
||
`作者：X` (e.g. `【月如无恨月长圆】（1-154）作者：陈西`). A real EPUB's `dc:title` would
|
||
be just the book name. Full-filename title ⇒ the file went through Readest's
|
||
**TXT→EPUB converter** (`bookService.ts` `/\.txt$/` → `TxtToEpubConverter`), which
|
||
sets `bookTitle = base filename` in the no-`《》` branch of `extractTxtFilenameMetadata`.
|
||
So "EPUB format" books can still be TXT-origin — check `src/utils/txt.ts`, not foliate-js,
|
||
when title looks like a filename. (Native Rust EPUB parser #4369 was NOT shipped in 0.11.2.)
|
||
|
||
Two root causes in `src/utils/txt.ts`:
|
||
1. `extractTxtFilenameMetadata` only pulled an author from `《》`-wrapped names; `【】`
|
||
names (the web-novel norm) got no filename author.
|
||
2. Greedy header capture `/[【\[]?作者[】\]]?[:：\s]\s*(.+)\r?\n/` grabbed a whole noisy
|
||
metadata line as the author.
|
||
|
||
Fix:
|
||
- `parseLabeledAuthor(base)` extracts the labeled `作者：X` from ANY filename; title stays
|
||
the full name. Only the *labeled* form is safe on a full filename — a bracketed/bare
|
||
fallback would mistake a leading `【title】` for the author.
|
||
- `isPlausibleAuthorName()` rejects a header match that looks like a blob (contains `:`/`：`,
|
||
a `\d{4,}` run, or length > 20) → falls back to the filename author. Applied in BOTH
|
||
`convertSmallFile` and `extractAuthorAndLanguage` (large-file path).
|
||
|
||
Note: the `著` form is handled for file *content* headers but NOT for filenames (kept minimal).
|
||
Reported files were 455 kB / 1.25 MB → both under the 8 MB `LARGE_TXT_THRESHOLD_BYTES`
|
||
(`convertSmallFile` path). Tests live in `txt-converter.test.ts` (faithful repro of both
|
||
reported strings). Related: [[bug-patterns]].
