Environment variables

The variables datui reads.

datui

Variable	What it does
`DATUI_CONFIG_DIR`	The config directory, in place of the platform’s (`~/.config/datui` on Linux). Saved views and format specs live there too
`DATUI_CACHE_DIR`	The cache directory, in place of the platform’s (`~/.cache/datui` on Linux)
`DATUI_FORMATS_PATH`	Directories of format specs and dictionaries, separated as `PATH` is, searched before `[formats] path`
`DATUI_LOG`	The log level: `error`, `warn`, `info`, `debug`, `trace` or `off`. Beats `log.level` in a file; `-c` and `--log-level` beat it
`DATUI_DEBUG`	`1` shows the debug overlay
`DATUI_GCP_PROJECT`	The Google Cloud project to list when projects cannot be searched, as `GOOGLE_CLOUD_PROJECT`
`DATUI_TRACE_FIRST_ROWS`	A file to write the time to, in Unix nanoseconds, once the first rows are drawn. For benchmarks

Terminal

Variable	What it does
`NO_COLOR`	Set to anything: no colors, the terminal’s own for everything
`COLORTERM`, `TERM`, `FORCE_COLOR`	How many colors the terminal draws: 24-bit, 256 or 16. Theme colors are brought down to fit
`COLORFGBG`	With `theme.mode = "auto"`, says whether the background is light or dark, for a terminal that does not answer when asked
`TERM_PROGRAM`	With `theme.mode = "auto"`, names the terminal whose last answer about its background picks the first frame’s theme; `TERM` when unset
`LC_ALL`, `LC_CTYPE`, `LANG`	With `display.unicode = "auto"`, the first one set says whether the terminal takes UTF-8; when it does not, glyphs are ASCII. With none set, Windows draws Unicode and other systems ASCII

Programs datui starts

Variable	What it does
`VISUAL`, `EDITOR`, `PAGER`	The inspector’s `o` opens text in the first one set, else `less` (on Windows, the system’s opener)

Cloud logins

Read as each provider’s own tools read them; a variable set but empty counts as unset. Connect to cloud storage says which login wins, and [cloud] env_files can read them from .env files.

Variable	What it does
`AWS_PROFILE`	The AWS profile for `s3://`, else `default`
`AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, `AWS_SESSION_TOKEN`	AWS keys, and the token of temporary ones
`AWS_REGION`, `AWS_DEFAULT_REGION`	The AWS region
`AWS_ENDPOINT_URL_S3`, `AWS_ENDPOINT_URL`, `AWS_ENDPOINT`	An S3-compatible endpoint (MinIO, R2, Ceph); the first one set
`AWS_CONFIG_FILE`, `AWS_SHARED_CREDENTIALS_FILE`	The AWS config and credentials files, in place of `~/.aws/config` and `~/.aws/credentials`
`GOOGLE_APPLICATION_CREDENTIALS`, `GOOGLE_SERVICE_ACCOUNT`, `GOOGLE_SERVICE_ACCOUNT_PATH`, `GOOGLE_SERVICE_ACCOUNT_KEY`	A Google Cloud service account or credentials file for `gs://`
`GOOGLE_CLOUD_PROJECT`, `GCLOUD_PROJECT`, `CLOUDSDK_CORE_PROJECT`, `GCP_PROJECT`	The Google Cloud project to list buckets in, after `DATUI_GCP_PROJECT`; the first one set
`CLOUDSDK_CONFIG`	The `gcloud` configuration directory, in place of `~/.config/gcloud`
`AZURE_STORAGE_CONNECTION_STRING`	An Azure storage connection string, with `AccountKey` or `SharedAccessSignature`
`AZURE_STORAGE_ACCOUNT_NAME`, `AZURE_STORAGE_ACCOUNT_KEY`, `AZURE_STORAGE_SAS_TOKEN`	An Azure storage account and its key or SAS token
`AZURE_TENANT_ID`, `AZURE_CLIENT_ID`, `AZURE_CLIENT_SECRET`, `AZURE_FEDERATED_TOKEN_FILE`	An Azure service principal, or AKS workload identity
`AZURE_CONFIG_DIR`	The Azure CLI’s directory, in place of `~/.azure`
