substitute-in-file-name does not work properly on Apollo Domain/OS GNU Emacs. The problem seems to occur when an environment variable contains a pathname which begins with //hostname, as shown in a log below: (emacs-version) "GNU Emacs 18.54.2 of Mon Jun 12 1989 on sdcapol2 (Domain/OS)" (getenv "JJ") "-idir //javelin/udr2/sasdjb/h -idir /usr/include" (getenv "KK") "-idir /udr2/sasdjb/h -idir /usr/include" (setq compile-command "/com/cc foo.c -b ../obj/foo.bin $JJ") "/com/cc foo.c -b ../obj/foo.bin $JJ" (substitute-in-file-name compile-command) "/javelin/udr2/sasdjb/h -idir /usr/include" (setq compile-command "/com/cc foo.c -b ../obj/foo.bin $KK") "/com/cc foo.c -b ../obj/foo.bin $KK" (substitute-in-file-name compile-command) "/com/cc foo.c -b ../obj/foo.bin -idir /udr2/sasdjb/h -idir /usr/include" The substitution of $JJ causes a loss of the string up to the //javelin in the environment variable! The second substitute, with env var KK works properly. I copied this from an emacs session run as: % emacs -q from a /bin/csh with SYSTYPE="bsd4.2", running Domain 9.7 Thanks, djb -- David J.

The substitution of $JJ causes a loss of the string up to the
//javelin in the environment variable! The second substitute,
with env var KK works properly.
This is explained by the following comment taken from the source for
substitute-in-file-name in src/fileio.c:
/* If /~ or // appears, discard everything through first slash. */
Presumably, this is desirable behavior. I think the problem is that it is
not well documented that substitute-in-file-name is intended to work on
file names, not on strings in general.
Congratulations on the first properly done bug report I've seen in a long
time!
