qgis_tmp_file: Manage temporary files

In paleolimbot/qgisprocess: Use 'QGIS' Processing Algorithms

Manage temporary files

Description

These functions create temporary files that can be used in calls to qgis_run_algorithm() or elsewhere. These files are created in a special temporary directory (qgis_tmp_base()) that should be periodically cleaned up using qgis_clean_tmp(). You can set your preferred vector and/or raster file extension using options(qgisprocess.tmp_vector_ext = "...") and/or options(qgisprocess.tmp_raster_ext = "..."), respectively.

Usage

qgis_tmp_file(ext)

qgis_tmp_folder()

qgis_tmp_vector(ext = getOption("qgisprocess.tmp_vector_ext", ".gpkg"))

qgis_tmp_raster(ext = getOption("qgisprocess.tmp_raster_ext", ".tif"))

qgis_tmp_base()

qgis_clean_tmp()

Arguments

ext	The file extension to be used.

Value

A character vector indicating the location of a (not yet created) temporary file.
