## 1. What is Midipix, and how is it different?
midipix is a development environment that lets you create programs
for Windows using the standard C and POSIX APIs. No compromises made,
no shortcuts taken.
If you are interested in cross-platform programming that reclaims
the notion of write once, compile everywhere; if you believe that the
'standard' in the C Standard Library should not be a null signifier;
and if you like cooking your code without #ifdef hell and low-level
minutiae, then this page is for you.
midipix makes cross-platform programming better, simpler and faster,
specifically by bringing a modern, conforming C Runtime Library to the
Windows platform. While the idea itself is not new, the approach taken
in midipix to code portability is radically different from that found
in other projects.

### 2.1. Building, installing and using a Midipix distribution
A Midipix distribution consists of the following:
* the native Midipix toolchain, consisting of perk, gcc, its dependencies,
and binutils,
* musl, a lightweight, fast, simple, and free libc[[1](https://www.musl-libc.org/faq.html)] used by Midipix,
* the Midipix runtime components that bridge the gap between the libc and the
executive subsystems of all Windows NT-derived Windows OS starting with and
including Windows XP, and
* a steadily increasing number of 3rd party open source packages, as expected in
any modern POSIX-compliant \*nix environment, including GNU coreutils, shells,
libraries such as ncurses, libressl, as well as Perl and Python.
Install the build-time dependencies listed in section [2.1.1](#211-build-time-dependencies),
clone this repository (e.g. ``git clone https://dev.midipix.org/build/midipix_build``)
and run the following command line:
```shell
./build.sh -a nt64 -b release -D zipdist -P -v
```
By default, the build will take place within ``${HOME}/midipix/nt64/release``
and package archive files and/or Git repositores will be downloaded into
``${HOME}/midipix/dlcache``. Consult sections [4.2](#42-build-variables) and
[4.5](#45-package-variables) for the list of available build/package variables
and how to override them.
Parallelisation is enabled by the above command line for both packages that can
be built independently of each other and ``make(1)`` via ``-j``, limited to the
amount of logical processors on the build host divided by two (2).

### 2.2. Deployment
On successful completion of the build, a ZIP archive containing the Midipix
distribution will be created inside ``${PREFIX}`` (see section [4.2](#42-build-variables).)
Create a directory on the target machine and extract the contents of the distribution
ZIP archive into it, run ``bash.bat``, and then ``/install.sh`` inside the resulting
self-contained Midipix installation shell window.
> N.B. The pathname of the target directory containing ``bash.bat`` and all other
distribution files must not contain whitespaces.
> N.B. The Midipix installer defaults to ``/dev/fs/c/midipix (C:\midipix)``. If left
unchanged, the distribution ZIP archive must not be extracted into a directory of the
same pathname.
> N.B. The user installing and using Midipix must have been delegated the ``SeCreateSymbolicLinkPrivilege``
("Create symbolic links") privilege[[3](https://docs.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/user-rights-assignment)] and additionally be a non-administrator account
owing to the UAC-related filtering policy of tokens introduced by Windows Vista[[4](https://docs.microsoft.com/en-us/previous-versions/dotnet/articles/bb530410%28v%3dmsdn%2e10%29)].

### 2.4. Troubleshooting
Midipix presently provides, inter alia, strace-like functionality via
ntctty's logging capabilities. This is available both through the regular
``strace(1)`` command as distributed, which however **must** be provided
with an absolute pathname without consideration for ``${PATH}``, as well
as directly via ``ntctty.exe`` for a session by running ``ntctty.exe``
with the ``--log-level 7`` option, e.g.:
```shell
$ #strace ls -la / # (incorrect, relative pathname)
$ strace /bin/ls -la / # (correct, absolute pathname)
$ ntctty.exe --log-level 7 -e /bin/ls -la /
$ ntctty.exe --log-level=7 -e /bin/ls -la /
$ ntctty.exe --log-level 7 -e /bin/sh -c "ls -la /"
$ ntctty.exe --log-level=7 -e /bin/sh -c "ls -la /"
```
By default, ``ntctty.exe`` log files are written into the /var/log/ntctty
directory; this may be adjusted with the ``--log-dir`` and/or
``--log-file`` options. ``strace(1)`` logs to stderr by default.

## 3.2. Adding a package
Packages are grouped into *build groups* according to sets of common package
variable defaults, such as ``${PKG_CFLAGS_CONFIGURE}, ${PKG_LDFLAGS_CONFIGURE}``
and ``${PKG_CONFIGURE_ARGS}``, and semantic interrelatedness, such as the
``native_runtime`` build group comprising the Midipix runtime components.
Packages may belong to more than one build group such as when subsumed by a shorthand
build group e.g. the ``dev_packages`` build group, as long as the default set of build
groups or as overriden on the command line does not entail group membership conflicts.
Build groups files beneath ``groups/`` named ``[0-9][0-9][0-9].<group name>.group``
contain package variable defaults, the alphabetically sorted list of contained
packages in ``<upper case group name>_PACKAGES``, and their package variables
sorted alphabetically with the exception of ``${PKG_DEPENDS}`` (if present,)
``${PKG_SHA256SUM}``, ``${PKG_URL}``, and ``${PKG_VERSION}``, and/or ``${PKG_URLS_GIT}``,
which are specified in this order.
Pick a build group according to the criteria mentioned, add the package to the
build group's list of contained packages in its corresponding file, and add the
set of package variables required (see above and section [4.5](#45-package-variables).)
Consult section [3.7](#37-patches-and-vars-files) if the package to be added
requires patches or additional code amending or replacing package build steps
or the entire package build. Consult section [4.1](#41-build-steps) for a list
of package build steps and how they are overriden.

dump. If ``-V build`` was specified, package logs will additionally be printed to standard
output. If ``-V xtrace`` was specified, ``xtrace`` will be set during package builds for
rudimentary debugging purposes. Additionally, packages using GNU autotools will, if
package configuration failed or appears relevant, log the configuration process in detail
in, most usually, ``${PKG_BUILD_DIR}/config.log``.
If ``--dump-on-abort`` was specified, a subset of the variables set and environment
variables exported will be written to ``${BUILD_WORKDIR}/${PKG_NAME}.dump``, which may
subsequently be used in order to obtain a package build shell environment with the

Packages, as well as groups, are interrelated through implicit as well as explicit parametrised,
typed relationships and form namespaces correspondingly.
These primarily, by expressing modalities of constraining, derivation, and/or subdividision, govern
the build and mirroring, etc. processes with regard to ordering constraints (e.g. ``depends``)
and derivation or sharing of sets of variables and/or patches and/or ``vars/`` files (e.g.
``group``, ``flavour``, ``inherit``) or build and/or source directories (e.g. ``module``,) etc.
They may, however, also be subject to enquiry for descriptive, diagnostic, or visualising purposes,
particularly as concerns the namespaces they form.
A list of relationship types follows:
| Type | Mode | Description |
| -------- | -------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| depends | implicit | Direct and recursively evaluated package dependency |
| suggests | explicit | Suggested or recommended optional package |
| group | implicit | Simple and overridable group variable inheritance (e.g. ``host_toolchain``, ``native_packages``) |
| inherit | both | Simple and overridable package variable inheritance |
| flavour | explicit | Exclusive package flavours set membership (e.g. ``vim_gtk``, ``vim_x11``) (conflicts w/ ``module``) |
| module | explicit | Package modularisation with implicit source and build directory sharing (e.g. ``gcc_stage1``, ``gcc_full``) (conflicts w/ ``flavour``) |

Package patches are applied prior and/or subsequent to (GNU autotools or similar) package
configuration during the ``configure_patch_pre`` and/or ``configure_patch`` build steps,
respectively (see section [4.1](#41-build-steps).) Patch files are searched for beneath
``patches/`` with the following globs and in-order:
* ``${PKG_NAME}-${PKG_VERSION}_pre.local.patch``
or ``${PKG_NAME}_pre.local.patch`` (for packages lacking ``${PKG_VERSION}``)

Package builds are divided up into consecutively executed build steps until
completion or aborted on failure unless relaxed mode is enabled by passing
``-R``.
Each build step corresponds to a function in the corresponding ``subr/pkg_*.subr``
script and may be overriden entirely by a function named ``pkg_<package name>_<build step>()``
or composed in terms of prior and/or subsequent execution by a function named
``pkg_<package name>_<build step>_pre()`` and/or ``pkg_<package name>_<build step>_post()``,
respectively, in the package's ``vars`` file. If a function named ``pkg_<package name>_all()``
exists, it will override all build steps.
Build step status is tracked on a per-package basis by state files beneath
``${BUILD_WORKDIR}`` following the format ``.<package name>.<build step>``;
package build completion corresponds to the pseudo-build step ``finish``.

## 4.4. File installation DSL
File and directory installation, comprising e.g. copying, moving, creating
symbolic links, setting owner and/or permission metadata, are expressed in
a descriptive domain-specific language and integrated with package building
via the package variable ``${PKG_INSTALL_FILES_V2}``, applying during
``install_files`` after the ``install_make`` build step, and ``${PKG_INSTALL_FILES_DESTDIR}``
and ``${PKG_INSTALL_FILES_DESTDIR_EXTRA}`` during ``install_subdirs``. The
``${PKG_INSTALL_FILES_V2}`` must adhere to the following syntax specified in EBNF:
```
(*
SH_GLOB_PATTERN = any valid portable shell pattern (see sh(1)); superset of PATHNAME
SH_SUBSTRING_PATTERN = any valid portable substring processing shell pattern (see sh(1));
superset of PATHNAME
PARAMETER = any valid portable shell variable name except that [0-9] may occur
the beginning
PATHNAME = any valid filename, directory name, relative or absolute pathname
excluding the characters NUL and NL
*)
spec = { op_flag, } op_unary, "=", op_spec, "\n", { spec } ;
| { op_flag, } op_binary, op_spec, "=" op_spec, "\n", { spec } ;
| "#" COMMENT ;
op_unary = "-" | "/" | "t" ;
op_binary = ":" | "!" | "@" | "+" | "g" | "m" | "o" | "T" ;
op_flag = "?" ;
op_spec = pattern_spec | PATHNAME | expr_spec | op_spec ;
pattern_spec = "%<", SH_GLOB_PATTERN, ">" ;
expr_spec = "%[", expr, { sexpr_spec }, "%]" ;
expr = [ "@" ], "0" .. "9" | "DNAME" | "FNAME" | "ITEM" | PARAMETER ;
sexpr_spec = sexpr_op_unary, SH_SUBSTRING_PATTERN, { sexpr } ;
sexpr_op_unary = "##" | "#" | "%%" | "%" ;
```
Single ``"="`` characters in ``spec``, the ``"%<"`` and ``"%["`` character
sequences in ``pattern_spec`` and ``expr_spec``, resp., and the ``sexpr_op_unary``
as well as ``sexpr_op_binary`` characters or character sequences may be
escaped with a single backslash (``"\"``.) ``SH_SUBSTRING_PATTERN`` differs
from ``SH_GLOB_PATTERN`` solely in that any of ``sexpr_op_unary`` and
``sexpr_op_binary`` occuring at the beginning of or in the former must
be escaped with a single backslash (``"\"``,) e.g. ``"#\#pattern"`` and
``"%\%pattern"``, etc. and ``"#pat\%ern"`` and ``%patt\#ern", etc., resp.
Named parameters (``PARAMETER``) are supplied via the ``-p name=value``
argument to ``rtl_install()``, whereas numbered parameters are for
internal usage only; the ``"DNAME"``, ``"FNAME"``, and ``"ITEM"`` parameters
lazily evaluate to the directory name, file (aka base) name, and full
pathname of the current item being processed relative to a specification
with a pattern in it.
The following parameters are defined by default during ``install_files``:

### 4.5. Package variables
The following variables are package-specific and receive their value from either
top-level defaults defined in ``midipix.env``, build group-specific defaults from the
build group the package pertains to and defined in its corresponding file beneath
``groups/``, or package-specific overrides defined either in the latter and/or in its
corresponding file beneath ``vars/``, with one of the following prefixes:
| Variable name prefix |
| ----------------------------------------------------- |
| DEFAULT |
| DEFAULT_``${BUILD_TYPE}`` |
| DEFAULT_``${GROUP_NAME}`` |
| ``${GROUP_NAME}`` |
| [PKG_``${RELATED_PACKAGE(S)}``] |
| [PKG_``${RELATED_PACKAGE(S)}``_``${BUILD_KIND}``] |
| PKG_``${NAME}`` |
| PKG_``${NAME}``_``${BUILD_KIND}`` |
Additionally, overrides may be specified on a per-build basis on the command-
line, with each variable prefixed w/ ``PKG_``, e.g.:
``./build.sh [ ... ] PKG_ZSH_CC="/usr/bin/clang"``.
The minimum set of package variables that must be provided is ``SHA256SUM, URL,
VERSION`` and/or ``URLS_GIT``, respectively.
