Command-line arguments for datui

Fields

paths: Vec<PathBuf>

Path(s) to the data file(s) to open. Multiple files of the same format are concatenated into one table (not required with –generate-config, –clear-cache, or –remove-templates)

skip_lines: Option<usize>

Skip this many lines when reading a file

skip_rows: Option<usize>

Skip this many rows when reading a file

skip_tail_rows: Option<usize>

Skip this many rows at the end of the file (e.g. to ignore vendor footer or trailing garbage)

no_header: Option<bool>

Specify that the file has no header

delimiter: Option<u8>

Specify the delimiter to use when reading a delimited text file

infer_schema_length: Option<usize>

Number of rows to use when inferring CSV schema (default: 1000). Larger values reduce risk of wrong type (e.g. int then N/A).

ignore_errors: Option<bool>

When reading CSV, ignore parse errors and continue with the next batch (default: false)

null_value: Vec<String>

Treat these values as null when reading CSV. Use once per value; no “=” means all columns, COL=VAL means column COL only (first “=” separates column from value). Example: –null-value NA –null-value amount=

compression: Option<CompressionFormat>

Specify the compression format explicitly (gzip, zstd, bzip2, xz) If not specified, compression is auto-detected from file extension.

format: Option<FileFormat>

Force file format (parquet, csv, tsv, psv, json, jsonl, arrow, avro, orc, excel). By default format is auto-detected from the file extension. Use this for URLs or paths without an extension.

debug: bool

Enable debug mode to show operational information

hive: bool

Enable Hive-style partitioning for directory or glob paths; ignored for a single file

single_spine_schema: Option<bool>

Infer Hive/partitioned Parquet schema from one file for faster load (default: true). Set to false to use full schema scan.

parse_dates: Option<bool>

Try to parse CSV string columns as dates (e.g. YYYY-MM-DD, ISO datetime). Default: true

parse_strings: Vec<String>

Trim whitespace and parse CSV string columns as date, datetime, time, duration, int, or float. Default: applied to all string columns. Use –parse-strings=COL (repeatable) to limit to specific columns, or –no-parse-strings to disable.

no_parse_strings: bool

Disable parse-strings for CSV (trim and type inference). Overrides config and default.

decompress_in_memory: Option<bool>

Decompress into memory. Default: decompress to temp file and use lazy scan

temp_dir: Option<PathBuf>

Directory for decompression temp files (default: system temp, e.g. TMPDIR)

excel_sheet: Option<String>

Excel sheet to load: 0-based index (e.g. 0) or sheet name (e.g. “Sales”)

clear_cache: bool

Clear all cache data and exit

template: Option<String>

Apply a template by name when starting the application

remove_templates: bool

Remove all templates and exit

sampling_threshold: Option<usize>

When set, datasets with this many or more rows are sampled for analysis (faster, less memory). Overrides config [performance] sampling_threshold. Use 0 to disable sampling (full dataset) for this run. When omitted, config or full-dataset mode is used.

polars_streaming: Option<bool>

Use Polars streaming engine for LazyFrame collect when available (default: true). Set to false to disable.

workaround_pivot_date_index: Option<bool>

Apply workaround for Polars 0.52 pivot with Date/Datetime index (default: true). Set to false to test without it.

pages_lookahead: Option<usize>

Number of pages to buffer ahead of the visible area (default: 3) Larger values provide smoother scrolling but use more memory

pages_lookback: Option<usize>

Number of pages to buffer behind the visible area (default: 3) Larger values provide smoother scrolling but use more memory

row_numbers: bool

Display row numbers on the left side of the table

row_start_index: Option<usize>

Starting index for row numbers (default: 1)

column_colors: Option<bool>

Colorize main table cells by column type (default: true). Set to false to disable.

generate_config: bool

Generate default configuration file at ~/.config/datui/config.toml

force: bool

Force overwrite existing config file when using –generate-config

s3_endpoint_url: Option<String>

S3-compatible endpoint URL (overrides config and AWS_ENDPOINT_URL). Example: http://localhost:9000

s3_access_key_id: Option<String>

S3 access key (overrides config and AWS_ACCESS_KEY_ID)

s3_secret_access_key: Option<String>

S3 secret key (overrides config and AWS_SECRET_ACCESS_KEY)

s3_region: Option<String>

S3 region (overrides config and AWS_REGION). Example: us-east-1
