27b941fdaf build: remove the ZiglingStep.makeInternal method
Rename the doCompile method to compile and add the run method.
The two methods are now called from the make method.

Add the help method, since the error handling of compile and run methods
are now separate.

Remove the obsolete comment for the compile method.

a86d4c2795 build: don't override the top level steps
When running `zig build -Dn=n`, the install and uninstall steps where
overridden in order to improve the description.

In recent version of Zig this is no longer allowed.

5c20e2b553 build: rename Exercise.baseName to name
The name "baseName" is confusing, since it refers to the UNIX basename
command, and not to the basename function in some programming languages
including Zig.

Use the std.fs.path.stem function to remove the file extension, instead
of slicing.

Remove the use of the assertion, since it is no longer necessary.
Instead, add a check to ensure that the exercise must be a Zig source
file in the validate_exercises function.

Update the validate_exercises function to check the last exercise, too.

69103a3b82 build: add the Exercise.addExecutable method
Currently addExecutable is called 3 times, unnecessarily making the code
more complex.

The method takes as argument the path to the exercises directory.

Additionally, use the new std.Build.ExecutableOptions.link_libc field.
The new field was added in ziglang/zig@adc9b77d5f on 2023-04-13.

Update the required Zig compiler version.
Note that I added the **current** zig version to the changelog, since
the reason for the change is known only to the person updating the
version.

ec1976e9ab build: reduce code duplication when setting the work path
Currently, the code for defining the path to the exercises directory is
duplicate 4 times.

Add the constants `healed_path` and `work_path`, and use work_path
instead of the duplicated if expression.  Update ZiglingStep to take
`work_path` instead of `use_healed` as argument.

Reduce code length by using `join` instead of `std.fs.path.join` and
replace the use of a slice with a tuple.

Additionally, in case of an error from the `join` function, use @panic
instead of unreachable.

Document why the special branch, when the exercises are healed by the
eowyn script, has been disabled.

3dd7cdcb3b build: make exercise output more reliable
Currently, ZiglingStep prints the raw exercise output.  This is not a
problem when executing `zig build` from the shell, but in a unit test it
is necessary to know when the exercise output ends.

Document that Exercise.output should not have trailing whitespace.
Ensure this is true by adding a check in the validate_exercises
function.

Remove trailing whitespace in exercises 68 and 99.

Simplify the output validation in ZiglingStep.makeInternal.
Checking that the length of the actual and expected output is the same
is not necessary, since trailing whitespace has been removed.  Simply do
an exact comparison.

Print the trimmed exercise output, instead of the raw output.
This will ensure that the exercise output always ends with only one LF
character.

Fix some small coding style issues.

30db9d105a build: avoid intermixed messages on the same line
In same cases, the progress messages from the compiler are intermixed
with the messages printed by ZiglingStep.

This intermixing appears in two cases:
  - when printing, e.g., the message "Checking 0_arrays2.zig..."
  - when printing the compiler errors

c6e055dd83 build: don't print errors in ZiglingStep.eval
Move the code for printing compiler errors and messages to the new
ZiglingStep.printErrors method.

Call printErrors in the Zigling.doCompile method, both in the normal and
error flow.

When handling an error from the Zig IPC, add the case when the compiler
was unable to return the executable path.

Before using the IPC, the error was
  "The following command exited with error code 1"
now it is
  "The following command failed to communicate the compilation result"

b39c7e61ef build: restore compatibility support again
Commit e214c44 (build: update ZiglingStep to the new API) broke again

e91c7a24f2 build: disable special case for zig build -Dhealed
The special case was added because it was used by the Eowyn github
workflow.

As a side effect, however, it prevents testing the normal case used by
users.

Disable it, until a better solution is found.

be782af7a3 build: restore compatibility support
Commit 0d56ba3 (build: restore the exercise chain) broke the
compatibility support for old compilers, due to the use of the

Use the normal for loop syntax; the change still keep the code readable.

Use the variable `n`, instead of `i`, when referring to the exercise
number; this will improve the readability.

c656536d3f build: simplify code and add tests

the correct order, and call it at the start of the build function.

Add tests, with 2 test cases.

d43f19ded8 build: add support for skipping exercises
Currently, exercises not working with the current Zig compiler are

index are no longer consistent.

Add the skip field to the Excercise struct.  Update ZiglingStep to
support it and add a new SkipStep step to support it when using the
standard build step.

67f369484c build: ensure the exercise links libc, when needed
When running, as an example, `zig build -Dhealed -Dn=93 test`, the build

ZiglingStep.

Ensure that exercises using libc are correctly built.

1cf910fb51 build: enable full parallelism when -Dhealed is set
The eowyn.sh script is used in a github workflow, but after
commit 0d56ba3 (build: restore the exercise chain), the github action
will take more time to complete.

Enable full build parallelism, when -Dhealed is true and -Dn is null.
Use the standard CompileStep and RunStep, instead of ZiglingStep.

On my PC, this change reduces the build time by about 30%.

59e28987da build: restore the exercise chain
The new parallel build support in Zig broke the exercise chain, so that
each esercise check is no longer strictly serialized.

  1. Add the Dexno option, in order to isolate the chain starting from a
     named exercise from the normal chain, thus simplify the code.

     The current code have an additional issue: it added 4 x n steps,
     making reading the help message or the list of steps very hard.

     Add only the `install`, `uninstall`, `zigling`, `test` and `start`
     steps.  The last three steps match the old steps `n`, `n_test` and
     `n_start`.

     The default step is zigling (note the singular form).

     The `install` step override the builtin install step, showing a
     custom description and matches the old `n_install` step.
     The uninstall step was added for consistency, so that the
     description is consistent.

     Setup a new chain starting at `zig build -Dexno=n start` so that it
     is stricly serialized.

     The behavior should be the same as the old one.

  2. Handle the code for all the exercises separately.

     Add only the `ziglings step`, making it the default step, in
     addition to the install and uninstall steps.

     Setup a new chain starting at the first exercise, to that it is
     strictly serialized.

     The behavior should be the same as the old one.

The current code has a know issue: the messages from the ZiglingStep and
the ones from the compiler compilation progress are interleaved, but each
message is written atomically, due to the use of `std.debug.getStderrMutex()`.

Update the README.md file.

45713ec8ab build: restore support for Zig 0.6.0
The version check for Zig 0.6.0 was incorrect since commit
971ab7f (Use a zig build script to run ziglings).

Move compatibility support to a separate file, in order to simplify
build.zig.

In case of incompatible version, exit with code 3 instead of 0, in order
to detect the case of failure in a test (to be implemented).

Remove the use of comptime when checking compatibility at the start of
the build function, since it is not necessary.
