in the format string. The format strings you can provide are::
$_ Package name
$@ Version
$% Compiler
$%@ Compiler & compiler version
$@ Version with '@' prefix
$% Compiler with '%' prefix
$%@ Compiler with '%' prefix & compiler version with '@' prefix
$+ Options
$= Architecture
$# 7-char prefix of DAG hash
$= Architecture with '=' prefix
$# 7-char prefix of DAG hash with '-' prefix
$$ $
You can also use full-string versions, which leave off the prefixes:
${PACKAGE} Package name
${VERSION} Version
${COMPILER} Full compiler string
${COMPILERNAME} Compiler name
${COMPILERVER} Compiler version
${OPTIONS} Options
${ARCHITECTURE} Architecture
${SHA1} Dependencies 8-char sha1 prefix
${SPACK_ROOT} The spack root directory
${SPACK_INSTALL} The default spack install directory, ${SPACK_PREFIX}/opt
Optionally you can provide a width, e.g. $20_ for a 20-wide name.
Like printf, you can provide '-' for left justification, e.g.
$-20_ for a left-justified name.
