One is to output progress information by re-writing the same display line by using a Carriage Return rather than a Line Feed at the end of each line. Another is to allow a single key stroke to trigger an action or interrupt operations.<br> <br> If the <span style="font-weight: bold;">ARGYLL_NOT_INTERACTIVE</span> environment variable is set, then:<br> <br> A Line Feed will be added to the end of each progress line.<br> <br> Any time it would wait for a single keystroke input, it will instead wait for and read the next character from stdin.<br> To facilitate flushing stdin, any return or line feed characters will be ignored, so a character other than return or line feed must be used to trigger activity.<br> <br> Note that while a reading is being made, a character input can abort the reading, just as with normal interactive mode.<br> <br> </div> <span style="font-weight: bold;">XDG_CACHE_HOME<br> <span style="font-weight: bold;"><br> </span></span> <div style="margin-left: 40px;">Argyll tries to follow the <a href="http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html">XDG Base Directory Specification</a>, and uses the <span style="font-weight: bold;">XDG_CACHE_HOME</span> environment variable to place per instrument calibration information (Eye-One Pro and ColorMunki instruments).<br> </div> <br> <span style="font-weight: bold;">XDG_CONFIG_DIRS<br> XDG_DATA_DIRS<span style="font-weight: bold;"><br> <span style="font-weight: bold;"></span></span></span><br> <div style="margin-left: 40px;">On Unix type operating systems, configuration and profiles for displays are placed relative to these environment variables.<br> <br> </div> <span style="font-weight: bold;">ARGYLL_COLMTER_CAL_SPEC_SET</span><br> <span style="font-weight: bold;">ARGYLL_COLMTER_COR_MATRIX</span><br> <br> <div style="margin-left: 40px;">Both of these can be used to set a default <span style="font-weight: bold;">CCMX</span> or <span style="font-weight: bold;">CCSS</span> colorimeter calibration file, equivalent to supplying a <span style="font-weight: bold;">-X</span> argument to spotread, dispcal, dispread and any other utility that allows using a colorimteter. The ARGYLL_COLMTER_CAL_SPEC_SET will take priority if both are set.<br> <br> </div> <br> <span style="font-weight: bold;">ARGYLL_IGNORE_XRANDR1_2<br> <br> </span> <div style="margin-left: 40px;">On an X11 system, if this is <span style="font-weight: bold;"></span>set (ie. set it to "yes"), then the presence of the XRandR 1.2 extension will be ignored, and other extensions such as Xinerama and XF86VidMode extension will be used. This may be a way to work around buggy XRandR 1.2 implementations.<br> </div> <br> <br> See <a href="Performance.html">Performance Tuning</a> for other variables.<br> <br> <br> </body> </html>
