## Building/running implementations
+The simplest way to run any given implementation is to use docker.
+Every implementation has a docker image pre-built with language
+dependencies installed. You can launch the REPL using a convenience
+target in the top level Makefile (where IMPL is the implementation
+directory name and stepX is the step to run):
+
+```
+make DOCKERIZE=1 "repl^IMPL^stepX"
+ # OR stepA is the default step:
+make DOCKERIZE=1 "repl^IMPL"
+```
+
+
+### Ada
+
+*The Ada implementation was created by [Chris Moore](https://github.com/zmower)*
+
+The Ada implementation was developed with GNAT 4.9 on debian. It also
+compiles unchanged on windows if you have windows versions of git,
+GNAT and (optionally) make. There are no external dependencies
+(readline not implemented).
+
+```
+cd ada
+make
+./stepX_YYY
+```
+

### Bash 4
```
### C
The C implementation of mal requires the following libraries (lib and
-header packages): glib, libffi6 and either the libedit or GNU readline library.
+header packages): glib, libffi6, libgc, and either the libedit or GNU readline
+library.

+`rlwrap`.

### Functional tests
-The are nearly 500 generic functional tests (for all implementations)
+The are over 600 generic functional tests (for all implementations)
in the `tests/` directory. Each step has a corresponding test file
containing tests specific to that step. The `runtest.py` test harness
launches a Mal step implementation and then feeds the tests one at
* To run all tests against a single implementation:
```
-make test^IMPL
+make "test^IMPL"
# e.g.
-make test^clojure
-make test^js
+make "test^clojure"
+make "test^js"
```
* To run tests for a single step against all implementations:
```
-make test^stepX
+make "test^stepX"
# e.g.
-make test^step2
-make test^step7

+make "test^ruby^step3"
+make "test^ps^step4"
```
### Self-hosted functional tests
as the test implementation and use the `MAL_IMPL` make variable
to change the underlying host language (default is JavaScript):
```
-make MAL_IMPL=IMPL test^mal^step2
+make MAL_IMPL=IMPL "test^mal^step2"
# e.g.
-make test^mal^step2 # js is default
-make MAL_IMPL=ruby test^mal^step2
-make MAL_IMPL=python test^mal^step2
+make "test^mal^step2" # js is default
+make MAL_IMPL=ruby "test^mal^step2"
+make MAL_IMPL=python "test^mal^step2"
```
+### Starting the REPL
+
+* To start the REPL of an implementation in a specific step:
+
+```
+make "repl^IMPL^stepX"
+
+# e.g
+make "repl^ruby^step3"
+make "repl^ps^step4"
+```
+
+* If you omit the step, then `stepA` is used:
+
+```
+make "repl^IMPL"
+
+# e.g
+make "repl^ruby"
+make "repl^ps"
+```
+
+* To start the REPL of the self-hosted implementation, specify `mal` as the
+ REPL implementation and use the `MAL_IMPL` make variable to change the
+ underlying host language (default is JavaScript):
+```
+make MAL_IMPL=IMPL "repl^mal^stepX"
+
+# e.g.
+make "repl^mal^step2" # js is default
+make MAL_IMPL=ruby "repl^mal^step2"
+make MAL_IMPL=python "repl^mal"
+```

-## Docker test environment
+## Dockerized testing
-There is a Dockerfile included in the `tests/docker` directory that
-builds a docker image based on Ubuntu Utopic that contains everything
-needed to run tests against all the implementations (except for MATLAB
-which is proprietary/licensed).
+Every implementation directory contains a Dockerfile to create
+a docker image containing all the dependencies for that
+implementation. In addition, the top-level Makefile contains support
+for running the tests target (and perf, stats, repl, etc) within
+a docker container for that implementation by passing *"DOCKERIZE=1"*
+on the make command line. For example:
-Build the the docker image using a provided script. WARNING: this will
-likely take over an hour to build from scratch and use more 3 GB of disk:
-```bash
-./tests/docker-build.sh
```
-
-Launch a docker container from that image built above. This will
-volume mount the mal directory to `/mal` and then give you a bash
-prompt in the container. You can then run individual mal
-implementations and tests:
-```bash
-./tests/docker-run.sh
+make DOCKERIZE=1 "test^js^step3"
```
-You can also specify a command to run within the container. For
-example, to run step2 tests for every implementation (except MATLAB):
-```bash
-./tests/docker-run.sh make SKIP_IMPLS="matlab" test^step2
+Existing implementations already have docker images built and pushed
+to the docker registry. However, if
+you wish to build or rebuild a docker image locally, the toplevel
+Makefile provides a rule for building docker images:
+
+```
+make "docker-build^IMPL"
```
+
**Notes**:
-* JVM-based language implementations (Java, Clojure, Scala): you will
- need to run these implementations once manually first before you can
- run tests because runtime dependencies need to be downloaded to
- avoid the tests timing out. These dependencies are download to
- dot-files in the /mal directory so they will persist between runs.
-* Compiled languages: if your host system is different enough from
- Ubuntu Utopic then you may need to re-compile your compiled
- languages from within the container to avoid linker version
- mismatches.
+* Docker images are named *"kanaka/mal-test-IMPL"*
+* JVM-based language implementations (Groovy, Java, Clojure, Scala):
+ you will probably need to run these implementations once manually
+ first (make DOCKERIZE=1 "repl^IMPL")before you can run tests because
+ runtime dependencies need to be downloaded to avoid the tests timing
+ out. These dependencies are download to dot-files in the /mal
+ directory so they will persist between runs.
