### Commentary:
## Some targets:
## check: re-run all tests, writing to .log files.
## check-maybe: run all tests whose .log file needs updating
## filename.log: run tests from filename.el(c) if .log file needs updating
## filename: re-run tests from filename.el(c), with no logging
### Code:
SHELL = @SHELL@
srcdir = @srcdir@
VPATH = $(srcdir)
SEPCHAR = @SEPCHAR@
# We never change directory before running Emacs, so a relative file
# name is fine, and makes life easier. If we need to change
# directory, we can use emacs --chdir.
EMACS = ../../src/emacs
# Command line flags for Emacs.
# Apparently MSYS bash would convert "-L :" to "-L ;" anyway,
# but we might as well be explicit.
EMACSOPT = -batch --no-site-file --no-site-lisp -L "$(SEPCHAR)$(srcdir)"
# Prevent any settings in the user environment causing problems.
unexport EMACSDATA EMACSDOC EMACSPATH GREP_OPTIONS
## To run tests under a debugger, set this to eg: "gdb --args".
GDB =
# The actual Emacs command run in the targets below.
# Prevent any setting of EMACSLOADPATH in user environment causing problems.

## Ignore any test errors so we can continue to test other files.
## But compilation errors are always fatal.
WRITE_LOG = >& $@ || { stat=ERROR; cat $@; }; echo $$stat: $@
## I'd prefer to use -emacs -f ert-run-tests-batch-and-exit rather
## than || true, since the former makes problems more obvious.
## I'd also prefer to @-hide the grep part and not the
## ert-run-tests-batch-and-exit part.
##
## We need to use $loadfile because:
## i) -L :$srcdir -l basename does not work, because we have files whose
## basename duplicates a file in lisp/ (eg eshell.el).
## ii) Although -l basename will automatically load .el or .elc,
## -l ./basename treats basename as a literal file (it would be nice
## to change this; bug#17848 - if that gets done, this can be simplified).
##
## Beware: it approximates `no-byte-compile', so watch out for false-positives!
