Only require a single expression argument. The remaining environment arguments are generally not required when debugging from the REPL. This makes expand much easier to use for casual debugging.
Since commit 15a8f2cfe5 the build order
must be as follows:
1. Bootstrap cyclone.scm using a pre-existing compiler.
2. Using cyclone from the previous step, build all libraries.
3. Using the artifacts from the previous two steps, build
icyc, examples, and tests.
This commit updates the Makefile prerequisites accordingly to reflect
this change in build order. Otherwise, Cyclone does not correctly
compile in parallel build mode with `-jN`.
On Unix-like operating systems stdio.h (which Cyclone seems to use
internally) is line-buffered. As such, the prompt will only be written
after a newline character is written (since the prompt itself doesn't
contain a newline) which is probably not what was
intended here. This commit fixes this issue by always flushing the
current-output-port after writing the prompt string.
The conditional variable assignment operator in Makefiles (`?=`) will
only assign a value if its not defined yet. However, CFLAGS/LDFLAGS are
commonly defined as environment variables to pass custom compiler/linker
flags (e.g. `-Os`). Unfortunately, Cyclone adds mandatory compiler flags
(without which it doesn't compile) via the conditional variable
assignment operator which is incorrect as these flags will not be added
if CFLAGS/LDFLAGS is defined in the environment. This commit fixes this
issue by appending flags to CFLAGS/LDFLAGS instead of using the
conditional assignment operator.
This seemed promising but fails when compiling cyclone:
cyclone -A . srfi/106.sld
