Manlio Perillo bb42451b0f build: use self when using @fieldParentPtr
Update PrintStep and SkipStep to use the `self` variable when getting
the parent pointer from Step.

This convention is used in `std.Build`.

Manlio Perillo 4ae67ebf1b build: don't install skipped exercises
Update the code in `zig build install` and `zig build -Dn=n install`, so
that exercises that must be skipped are not installed, since it will
cause an error.  Ensure that a skip message is printed.

Manlio Perillo 185a40eb75 build: fix `zig build -Dhealed install`
The command fails because the path to the exercises directory was
incorrectly set to "exercises" instead of `work_path`.

The bug was introduced in commit b56bb7b
(build: enable full parallelism when -Dhealed is set).

Remove the comment about not using multi-object loop, since it is
confusing.

Manlio Perillo 1dd5852bec build: use multiline string literals when necessary
Update the output and hint fields in the `exercises` slice to use a
multiline string literal when the string have multiple lines or use the
`"` character.  This will greatly improve readability.
Additionally, remove the trailing whitespace on each line and check it
in the validate_exercises function.

Update the output comparison logic in ZiglingStep, since the current
code assumes that the string has only one line.

Update test/tests.zig to use the new `CheckNamedStep` in test case 1,
since RunStep.StdIo.Check is no longer able to correctly check the
output.

Fixes #283

Manlio Perillo 0cd86d2f9b build: add the healed-path option
This is necessary in the unit tests, to ensure each test case use a
different exercises directory.

Update test/tests.zig to use the new healed-path option, ensuring that
each temp directory is removed.

In test case 3, 4 and 5, move case_step as the first step in the
dependency chain.  This will improve the build summary tree.

In test case 5, remove the dependency to heal_step, since it is not
necessary.

Manlio Perillo a5d93c0b20 build: improve coding style in ZiglingStep
- Use an anonymous struct when initializing std.Build.Step.
  - Rename the builder parameter in the create method to b
  - Avoid lines too long

Additionally:
  - In the run method, rename output to raw_output in order to make the
    next variable names shorter.
  - In the compile method, rename zig_file to path.

Manlio Perillo 771b499cbc build: use @panic("OOM") instead of unreachable
The code in ZiglingStep copied the error handling used in std.Build in
the past.

Use @panic("OOM") when the error is caused by the allocator failing to
allocate memory.

Manlio Perillo 40cbee8fa2 build: fix incorrect error handling in ZiglingStep.compile
When handling the error from the eval method, some possible errors are
ignored.  The make method will only print the exercise hint and the
help message.

Print the unexpected error message, in the else prong.
Note that FileNotFound can also be considered unexpected.

Manlio Perillo 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.

Manlio Perillo a86d4c2795 build: don't override the top level steps

In recent version of Zig this is no longer allowed.

Manlio Perillo 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.

Manlio Perillo 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.

Manlio Perillo 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.

Manlio Perillo 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.

Manlio Perillo 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

Manlio Perillo 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"

users.

Disable it, until a better solution is found.

Manlio Perillo be782af7a3 build: restore compatibility support
Commit 0d56ba3 (build: restore the exercise chain) broke the

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