SnapOtterandGitHub 607c24895b Improve docs search UX, dash cleanup, and colored modality tool icons (#338)
* feat(docs): improve search UX

- Hide the 'Search by Pagefind' branding in the search dialog footer
- Replace the 'No results found.' message shown before any query with a
  friendly hint (detected via empty-input :placeholder-shown state)
- Tune placeholder, empty-state, and results-heading copy; show a few
  sub-section matches per result (pageResultCount)

* docs: replace double-dash em-dash substitute with single dash

Swept prose ' -- ' to ' - ' and numeric ranges (e.g. 2--20 to 2-20)
across the documentation. CLI flags and code blocks left untouched.

* fix(landing): show colored category icons on modality tool pages

The /tools/<modality>/ pages rendered bare name+description cards with no
icon or color. Port the colored, category-tinted icon card from /tools/
so modality pages match the main catalog (icon, tint, 'Learn more').

Split a CSV into smaller files by row count.

Split CSV

Split a large CSV or TSV file into smaller files by row count. Returns a ZIP archive containing the parts.

API Endpoint

POST /api/v1/tools/files/split-csv

Accepts multipart form data with a CSV file and a JSON settings field.

Parameters

Parameter Type Required Default Description
rowsPerFile integer No 1000 Number of data rows per output file (1-1,000,000)
keepHeader boolean No true Repeat the header row in each output file

Example Request

curl -X POST http://localhost:1349/api/v1/tools/files/split-csv \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@large-dataset.csv" \
  -F 'settings={"rowsPerFile": 500, "keepHeader": true}'

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/large-dataset_parts.zip",
  "originalSize": 1048576,
  "processedSize": 1050000
}

Notes

  • Output is always a ZIP archive containing the split CSV parts, named sequentially (e.g. part-1.csv, part-2.csv).
  • When keepHeader is true, each part includes the original header row so each file can be used independently.
  • Both CSV and TSV files are accepted as input.
  • The row count refers to data rows only; the header row is not counted.
