245 The path to a config file can be given via the $imv_config environment
246 variable. If not found, imv will search for it in the following
247 locations:
248 • $XDG_CONFIG_HOME/imv/config (recommended)
250 • $HOME/.config/imv/config
252 • $HOME/.imv_config
254 • $HOME/.imv/config
256 • /usr/local/etc/imv_config
258 • /etc/imv_config
260 A default config file is shipped with imv into /etc/imv_config
262 For documentation on the config file format, see imv(5).
264
266 When imv executes a shell command, it provides a number of environment
267 variables, exposing imv’s state. These environment variables are also
268 available when customising the window’s title, or the overlay text.
269 $imv_pid
271 The pid of this instance of imv. Useful for running imv-msg in
272 scripts.
273 $imv_current_file
275 Path of currently selected image.
276 $imv_scaling_mode
278 Name of the current scaling mode.
279 $imv_loading
281 1 if a new image is loading, 0 otherwise.
282 $imv_current_index
284 Index of current image, from 1-N.
285 $imv_file_count
287 Total number of files.
288 $imv_width
290 Width of the current image.
291 $imv_height
293 Height of the current image.
294 $imv_scale
296 Scaling of current image in percent.
297 $imv_slideshow_duration
299 Number of seconds each image is shown for.
300 $imv_slideshow_elapsed
302 How long the current image has been shown for.
303
305 imv can accept commands from another process over a unix socket. Each
306 instance of imv will open a unix socket named
307 $XDG_RUNTIME_DIR/imv-$PID.sock. If $XDG_RUNTIME_DIR is undefined, the
308 socket is placed into /tmp/ instead.
309 The imv-msg(1) utility is provided to simpliy this from shell scripts.
