Path input widget — path_input • blockr.io

A Shiny module that provides a text input with server-side file/directory autocomplete. Used by the read and write blocks to replace shinyFiles browser widgets.

Usage

path_input_ui(id, prefix = NULL, upload_id = NULL)

path_input_server(
  id,
  data_dir = reactive(""),
  mode = c("file", "directory"),
  extensions = NULL
)

Arguments

id: Module namespace ID.
prefix: Optional initial prefix text shown before the input (typically the data directory path).
upload_id: Optional ID of a hidden Shiny fileInput to wire up for upload-icon click and drag-and-drop. When non-NULL, an upload icon button is rendered inside the input field and the container gets a data-upload-target attribute pointing to this ID.
data_dir: Reactive returning the current data directory path (from board options). Empty string means no data directory.
mode: Either "file" or "directory". Controls which entries are selectable in the autocomplete dropdown.
extensions: Optional character vector of file extensions (without dots) to show in autocomplete. Defaults to NULL, which shows all rio-supported formats. Use e.g. "rtf" to restrict to RTF files only.

Value

path_input_ui() returns a tagList with the widget HTML. path_input_server() returns a reactive containing the current path text value.
