Catalogs

A catalog is one TOML file of named datasets, local or remote. The home screen lists each catalog as a section under its label, one row per dataset, wherever the data lives. Logins are in Cloud connections.

datui catalog show examples

Catalog	File	Written by
Yours, `My datasets`	`catalog.toml` in the config directory	You, and `Ctrl`+`D` on the home screen
A team’s or a project’s	Any `*.toml` in `catalogs/` in the config directory, or a file elsewhere that `catalogs` in the config lists	You; datui only reads it
`Example datasets`	Comes with datui; `datui catalog show examples` prints it	datui

Command	Does
`datui catalog show`	List the catalogs: id, label, datasets, where each comes from, and its file
`datui catalog show NAME`	Print a catalog’s file: `mine`, `examples`, or another catalog’s file name
`datui catalog check FILE`	Check a file and list its datasets; a mistake is named by its line, with the fix
`datui config init`	Write the config file, an empty `catalog.toml` and the `catalogs/` directory; an existing `catalog.toml` is kept

A catalog file

The top level holds label and description. Every other table is one dataset: its key is a short id (lowercase letters, digits and -), and name is its row:

label = "My datasets"

[sales]
name = "Sales"
path = "~/datasets/sales.parquet"
description = "Monthly sales"
columns.region = { description = "Sales region", values = { NE = "Northeast", W = "West" } }
columns.amount = { description = "Net of returns", unit = "USD" }

[weather]
name = "Weather"
url = "s3://noaa-ghcn-pds/parquet/"
auth = "anonymous"
bookmarks."Daily highs, 2024" = "by_year/YEAR=2024/ELEMENT=TMAX/"

[penguins]
name = "Penguins"
url = "https://vincentarelbundock.github.io/Rdatasets/csv/palmerpenguins/penguins.csv"
size = 16480

[nas]
name = "NAS data"
path = "/mnt/nas/data"

A dataset in a private store names the connection that reads it; replace <BUCKET> and <CONNECTION> with yours:

[orders]
name = "Orders"
url = "s3://<BUCKET>/orders/"
connection = "<CONNECTION>"

Top-level key	Meaning
`label`	The section’s title. Default: `My datasets` for `catalog.toml`, else the id
`description`	What the catalog is for

Dataset key	Meaning
`name`	Required. The row’s name, unique in the catalog
`path`	A local file or directory. `~` and `$VAR` expand; a relative path is relative to the catalog file
`url`	An `s3://`, `gs://` or Azure file or directory, or an `http://` or `https://` data file
`auth`	Object-store `url` only: `auto` (the default) or `anonymous`
`connection`	Object-store `url` only: the `[[cloud.connections]]` entry whose login reads it
`description`, `publisher`, `license`	Shown in the details pane and the Documentation view
`homepage`, `documentation`	Links: the dataset’s page, and an `https://` link to the publisher’s documentation of its columns
`size`	HTTP(S) `url` only: about how many bytes the file is, shown as `~33 MB` until datui measures it
`columns.NAME`	What a column means; see Columns
`bookmarks."Name"`	A place inside a directory to start from, relative to the dataset’s `path` or object-store `url`

A dataset has exactly one of path and url. No two datasets in a catalog share a name or a location.

Location	`Enter`	Read with
Local file	Opens it
Local directory	Steps inside
Object-store file	Opens it	`auth` or `connection`
Object-store directory	Steps inside. `Backspace` at its top comes back to the list	`auth` or `connection`
HTTP(S) file	Downloads it, after asking, and opens it; a `public` file under 50 MB is downloaded without asking, and asks if it passes 50 MB	No login

Reading	Means
`auth = "auto"`	As the URL typed at `~` would be: the login found for that cloud, unsigned when there is none or it is refused
`auth = "anonymous"`	No credentials and no signature, whatever login the machine has
`connection = "<name>"`	That connection’s login and nothing else. Its `kind` must match the URL, and an Azure connection’s `account` the URL’s account

HTTP(S) is always read with no login, and its URL must name a file datui reads: a web server has no listing to browse. Name a connection with connection, not in the URL: s3://onprem@bucket/ is refused.

A catalog holds references, not data. Nothing is read until a dataset is opened or entered, so a remote directory’s row says dataset until then; a web file’s row sends one HEAD when it is selected, to show its real size. A local path with nothing there stays listed and says missing.

Columns

A dataset can say what its columns mean. The home screen’s details pane lists them, Ctrl+E shows them in the Documentation view, and once the data is open the Info panel and the inspector explain each one. Write a column on one line; give a long legend a table of its own:

[weather]
name = "GHCN daily"
url = "s3://noaa-ghcn-pds/parquet/"
auth = "anonymous"
documentation = "https://www.ncei.noaa.gov/pub/data/ghcn/daily/readme.txt"

columns.DATA_VALUE = { description = "Data value for ELEMENT", unit = "per ELEMENT" }
columns.Q_FLAG.description = "Quality flag; blank is normal"

[weather.columns.Q_FLAG.values]
"" = "did not fail any quality assurance check"
S = "failed spatial consistency check"

Column key	Meaning
`description`	What the column holds. Shown in Info’s `About` column and under the inspector’s value
`unit`	Its unit or format, shown after the description: `tenths of mm`, `YYYYMMDD`
`values`	Code to meaning. The inspector shows the meaning of the value under the cursor; `""` is what a blank or null value means. Codes match exactly, case included

A column with its own [id.columns.NAME.values] table is written with dotted keys, columns.NAME.description = "...". Written as an inline table, columns.NAME = { ... }, TOML closes it, and the values table after it is an error; datui catalog check names the line and the fix.

A bookmark is listed under its dataset. Enter on it opens the place whole, as one table; → steps inside.

Your catalog

Ctrl+D on a home row adds it to catalog.toml: a file, a directory, an object-store place, or a heading’s directory, under the row’s name, with an id made from the name. A row from another catalog is copied with its location, login and description. Ctrl+D or Delete on a row of catalog.toml forgets it: its table, and the tables under it, go; the rest of the file, comments included, stays as written. datui never writes any other catalog file.

Directories that Ctrl+D kept before 0.4.0 move into catalog.toml the first time the home screen opens.

Team catalogs

Drop a catalog file into catalogs/ in the config directory (~/.config/datui/catalogs/ on Linux, beside catalog.toml): every *.toml there is a catalog, read in file-name order, and other files are ignored.

A catalog file elsewhere, such as a team’s on a share, is listed in the config; a relative path is relative to the config file that lists it, so a team’s shared config can list its catalog beside it. Replace <CATALOG_FILE> with the file’s path:

catalogs = ["<CATALOG_FILE>"]

A file you cannot rename or edit is listed as a table, path and an id or a label of its own. Replace <CATALOG_FILE> with the file’s path:

catalogs = [{ path = "<CATALOG_FILE>", id = "acme", label = "ACME" }]

Key	Meaning
`path`	Required. The file
`id`	The catalog’s id, in place of the file’s name: what `[home] hide` names, and what decides a `public` catalog
`label`	The section’s title, in place of the file’s own `label`

A catalog file’s name, without .toml, is its id. A listed file that is not there is skipped with a warning, as a missing import is.

A catalog file with a mistake, catalog.toml included, is left out rather than stopping datui: its file:line: message goes to standard error and the log, and its section on the home screen reads ▲ acme.toml:3 ... in place of its rows. Two files of one id, wherever they are, or one named mine.toml, are such a mistake, naming both. Ctrl+D never writes a catalog.toml it cannot read; datui catalog check names the mistake and exits non-zero. catalogs adds up across imported files, imports first. The sections follow My datasets: catalogs/ in file-name order, then the listed files, then Example datasets.

To	Do
Replace the example datasets	A catalog file named `examples.toml`, in `catalogs/` or listed: it replaces the whole catalog; nothing bundled is merged in
Rename a catalog you cannot edit	List it as `{ path = "...", id = "acme", label = "ACME" }`: a shared `catalog.toml` or `examples.toml` then takes neither role
Hide a catalog, or one entry	`[home] hide = ["acme", "examples/nyc-taxis"]`: a catalog by its id, an entry as `catalog/id`; hides add up across files, and a name that hides nothing is warned about (`public`, the id before 0.4.0, says it is now `examples`). `datui catalog show` marks a hidden catalog `(hidden by home.hide)`
Edit the example datasets	`datui catalog show examples > examples.toml`, move `examples.toml` into the config directory’s `catalogs/` (`~/.config/datui/catalogs/` on Linux), then edit it. Written there directly, the shell empties the file before datui reads it

Catalogs are apart from RECENT. Whatever you open goes into RECENT whether or not a catalog names it.

The example datasets

This is the catalog that comes with datui, as datui catalog show examples prints it: a worked example of every key.

The bundled examples catalog: data its publishers host and maintain, read with no login. These are remote links, not bundled data: object-store roots browse, HTTP(S) files open directly, and nothing is fetched until an entry is opened.

Each entry is labeled with its actual scope, and must be readable without credentials or requester-pays access. An HTTP(S) file gives its size in bytes, as measured when it was added: its row shows it, and one under 50 MB is downloaded without asking. A rolling file’s size is a typical one.

An entry may carry documentation: the publisher’s documentation of its columns, and columns notes taken from it, never from memory. bookmarks names places inside a directory dataset to start from; each must list with no login.

A raw.githubusercontent.com link names a commit, not a branch, so a push upstream can’t move, rename or change the file under its size.

The weekly Example datasets workflow checks every entry and every bookmark.
