Settings

Set these in config.toml (datui config init writes one with every key commented out), or for one run with -c KEY=VALUE:

printf 'a,b\n1,2\n' | datui -c display.row_numbers=true

A flag beats -c, which beats the config files, which beat the defaults. datui config keys lists every key with its value in effect and where it was set. See Configure datui for where the file lives, imports, the theme and troubleshooting.

Type	Written as
size	A number and a unit: `512MiB`, `2GiB`, `100KiB` (`MB`, `GB` are powers of 1000). `0` needs none
duration	A number and a unit: `250ms`, `1.5s`, `2m`
list	In a file, a TOML array; with `-c`, `a,b` or the array
color	A name (`red`, `bright_blue`, `default`), `#rrggbb` or `indexed(0-255)`

Top level

Key	Type	Default	Flag	Description
`import`	list	`[]`		Config files merged in before this one, in order; this file’s own values win. Paths may be relative to this file, or use ~ and $VAR.
`catalogs`	list of path \| { path, id, label }	`[]`		Catalog files elsewhere, listed on the home screen after catalog.toml and the config directory’s catalogs/*.toml, each a section; see Catalogs. Each is a path, or { path, id, label } to give it another id or label. Paths may be relative to this file. Adds up across imports.

Read

[read] How files are read. A file’s own layout (delimiter, header, rows to skip) is a flag for that file, not a setting.

Key	Type	Default	Flag	Description
`read.infer_types`	bool \| list of columns	`true`	`--infer-types`	Read string columns as dates, times, durations or numbers where every value parses, after trimming: true for all, false for none, or a list of columns. CSV, and dates in JSON. A column with a leading zero (02134) stays text; a later value that does not parse is null, and the Notes tab counts them.
`read.parquet_schema`	union \| first	`"union"`		A partitioned Parquet dataset’s schema: union is every column any file has, from their footers; first lets Polars take one file’s.
`read.decompress_in_memory`	bool	`false`		Decompress a compressed CSV, TSV or PSV into memory instead of to a temp file.
`read.temp_dir`	path	unset	`--temp-dir`	Directory for decompression temp files. Unset: the system’s.
`read.follow_interval`	duration	`"250ms"`		With –follow, how often the file is checked for new rows, or on Linux the least time between two reads, 10ms to 1m. Appends within one interval are one refresh.
`read.exact_count_files`	integer	`50000`		A dataset of more files than this shows a row count estimated from a sample of its footers until c in the Info panel counts it; 0 always counts.
`read.memory_warning`	size	`"1GiB"`		Ask before reading more than this of a file whole into memory (JSON, Avro, ORC, Excel and the other formats read in memory); 0 never asks.
`read.audio_float`	bool	`false`		Show integer audio samples as float in [-1, 1].

CSV

[csv] CSV, TSV and PSV. A delimited format spec takes these keys too.

Key	Type	Default	Flag	Description
`csv.comment`	string	unset	`--comment`	Lines starting with this are comments, before the header and among the data.
`csv.header_join`	string	`" "`		Joins a column’s names when –header-rows names several lines.
`csv.skip_initial_space`	bool	`false`	`--skip-initial-space`	Ignore the spaces after a delimiter, so padded numbers are numbers and a cell of spaces is null.
`csv.null_values`	list	`[]`	`--null`	Values read as null: VAL in every column, COL=VAL in column COL only. –null is repeatable and replaces this list.
`csv.infer_rows`	integer	`1000`	`--infer-rows`	Rows read to infer column types.
`csv.ignore_errors`	bool	`false`	`--ignore-errors`	Skip rows that do not parse instead of failing.

`display.notes_accent`	bool	`true`		Accent the i key when datui has noticed something about the data.
`display.mouse`	bool	`true`	`--mouse`	Take the mouse: the wheel scrolls, a click selects. false leaves it to the terminal.
