Environment variables

Specifying the configuration file

Use of the -c flag can be avoided by setting the BLACONFIG environment variable. The following are equivalent:

bla herfd -c=/path/to/config.ini -e=9713 Aufoil1

export BLACONFIG=/path/to/config.ini
bla herfd -e=9713 Aufoil1

Specifying the emission energy

Use of the -e flag can be avoided by setting the BLAENERGY environment variable. The following are equivalent:

bla herfd -c=/path/to/config.ini -e=9713 Aufoil1

export BLAENERGY=9713
bla herfd -c=/path/to/config.ini Aufoil1

You can also avoid using the -e flag by setting a single energy in the emission line of the configuration file. (Of course, having only a single energy in that list will hamper the rixs, map, and xes tasks....)

Specifying metadata

Use of the -x flag can be avoided by setting the BLAXDIINI environment variable. The following are equivalent:

bla herfd -c=/path/to/config.ini -x /path/to/xdi.ini -e=9713 Aufoil1

export BLAXDIINI=/path/to/xdi.ini
bla herfd -c=/path/to/config.ini -e 9713 Aufoil1

The ini file for the XDI metadata can also be specified in the [files] block of the main configuration file.

Each environment variable is overridden by its respective command line switch.
