Hello all,
In the future it will be important for Guildhall modules to have a lower
priority than in the search path than Guile's core modules. The reason
is that Guildhall has several portable SRFIs, some of which will be
superceded by efficient native implementations in core Guile. One such
example is SRFI-41, which will soon be replaced by a superior version in
Guile core.
There are two ways to arrange for Guildhall's directory to have a lower
priority than Guile's core modules:
* If you added Guildhall's directory to the GUILE_LOAD_PATH environment
variable, then make sure "/home/USERNAME/.local/share/guile/site/2.0"
comes last, and add a special dummy path component composed of three
dots (...) immediately before it. For example:
GUILE_LOAD_PATH=...:/home/<USER>/.local/share/guile/site/2.0
or:
GUILE_LOAD_PATH=/foo:...:/home/<USER>/.local/share/guile/site/2.0
In Guile 2.0.7 and later versions, all path components after the "..."
will be added after the default Guile search path. In earlier
versions, the "..." will do nothing but harmlessly await your future
upgrade to 2.0.7+ :)
* If you added Guildhall's directory to the %load-path variable from
within Guile itself (perhaps in .guile) then append it to the *end* of
the load path as follows:
(set! %load-path
(append %load-path
(list "/home/<USER>/.local/share/guile/site/2.0")))
Ian, can you please update your Guildhall "Getting-Started" document
appropriately? <https://github.com/ijp/guildhall/wiki/Getting-Started>
Thanks!
Mark
