I want to be able to use the same config file across all of my machines, and my username is unfortunately different at work, so absolute paths are difficult for me to use.
Is there a common way to specify non-absolute directories for LIBREF-* variables in the GNU APL preferences file? It seems like tilde expansion and environment variables are not interpreted. But I can't find any info on this through Google.
Thank You for Your time.
EDIT 1:
To be clear, I have tried the following:
LIBREF-0 = $HOME/Documents/apl-libs/lib0
But it seems to show up inside of )LIBS with $HOME
intact.
In my search through the documentation, I came across a reference to the $APL_LIB_ROOT
environment variable.
If this is set and there are no other definitions for library directories in both the system and user preferences files, then GNU APL will use the following directory structure to populate these values:
LIBREF-0 = $APL_LIB_ROOT/workspaces
LIBREF-1 = $APL_LIB_ROOT/wslib1
LIBREF-2 = $APL_LIB_ROOT/wslib2
LIBREF-3 = $APL_LIB_ROOT/wslib3
LIBREF-4 = $APL_LIB_ROOT/wslib4
LIBREF-5 = $APL_LIB_ROOT/wslib5
LIBREF-6 = $APL_LIB_ROOT/wslib6
LIBREF-7 = $APL_LIB_ROOT/wslib7
LIBREF-8 = $APL_LIB_ROOT/wslib8
LIBREF-9 = $APL_LIB_ROOT/wslib9
However, at least on the system I am using (GNU Guix), there are entries in the system-wide configuration file for the included libraries for 3, 4, and 5 (which is what is intended by upstream).
This works around my problem, but was not clearly documented anywhere I could find, so I figured it would do well to be an answer. Below are some links I found helpful while discovering this.
