and this can now throw in edge cases where `getCurrentDir` throws.
`relativePath` also now works for js with `-d:nodejs`.
- JavaScript and NimScript standard library changes: `streams.StringStream` is
now supported in JavaScript, with the limitation that any buffer `pointer`s
used must be castable to `ptr string`, any incompatible pointer type will not
work. The `lexbase` and `streams` modules used to fail to compile on
NimScript due to a bug, but this has been fixed.
The following modules now compile on both JS and NimScript: `parsecsv`,
`parsecfg`, `parsesql`, `xmlparser`, `htmlparser` and `ropes`. Additionally
supported for JS is `cstrutils.startsWith` and `cstrutils.endsWith`, for
NimScript: `json`, `parsejson`, `strtabs` and `unidecode`.
- Added `streams.readStr` and `streams.peekStr` overloads to
accept an existing string to modify, which avoids memory
allocations, similar to `streams.readLine` (#13857).
