.Sh DESCRIPTION
KISS packages are comprised of a directory and the series of files contained
within.
The name of the package is derived from its directory name.
The files which comprise the system are as follows:
.TS
center box tab(|);
lb|lb
l|l.
File | Required
_
build | yes
checksums | no
depends | no
sources | no
version | yes
pre-remove | no
post-install | no
.TE
.Ss build
The
.Pa build
file is executed in the directory containing the package's extracted
sources.
Unlike other distributions, a
.Ic cd
is not needed as sources have their top-level directory components stripped
away.
.Pp
The build file is given two arguments: the destination directory (where
artifacts should be installed) and the first field of the package's version file
(verbatim).
.Pp
The build file is given a modified environment containing DESTDIR, KISS_ROOT,
GOPATH and generic defaults for toolchain variables (if unset by the user).
The toolchain defaults are as follows:
.Bd -literal -offset indent
AR=ar
CC=cc
CXX=c++
NM=nm
RANLIB=ranlib
RUSTFLAGS="--remap-path-prefix=$PWD=. $RUSTFLAGS"
GOFLAGS="-trimpath -modcacherw $GOFLAGS"
.Ed
.Ss checksums
The
.Pa checksums
file is generated by the package manager
.Ql ( kiss c pkg )
and is derived from files listed in the package's
.Pa sources
file.
Directories and git repositories do not require checksums.
.Pp
Checksum verification can be disabled for a source by replacing its checksum
with 'SKIP' in the checksums file.
The package manager will notify you when this occurs.
.Ss depends
The
.Pa depends
file contains the package's dependencies listed one per line in alphabetical
order.
Duplicate entries are not supported.
The second optional field denotes the dependency type (unset for runtime,
.Dq make
for compile-time).
Lines beginning with
.Ql #
are comments.
.Ss sources
The
.Pa sources
file contains the package's sources one per line.
A valid source is a URL to a file, relative path, absolute path or Git
repository.
The optional second field denotes the relative destination directory.
Lines beginning with
.Ql #
are comments.
.Pp
Git repositories must be prefixed with
.Ql git+ .
An optional suffix is supported to checkout a specific branch
.Ql ( @BRANCH )
or commit
.Ql ( #COMMIT ) .
All clones are shallow where supported by the remote server.
If no suffix is used, master is cloned.
.Pp
The following markers can be used to substitute version information.
These are replaced at runtime with their respective values.
Literal markers can be escaped by prepending a backslash.
.TS

l|l.
VERSION | The first field of the version file verbatim.
RELEASE | The second field of the version file verbatim.
MAJOR | The first component of VERSION split on .-_+
MINOR | The second component of VERSION split on .-_+
PATCH | The third component of VERSION split on .-_+
IDENT | All other components.
PACKAGE | The name of the package.
.TE
.Ss version
The
.Pa version
file is a single line split into two mandatory fields.
The first field is the package's version and the second field the version of the
repository files themselves.
.Pp
If the package follows its upstream release schedule, the first field should
match the upstream version number.
If the source is a Git repository, the version should be set to
.Ql git .
If a specific git commit is used, the version number should match accordingly.
.Ss pre-remove
The
.Pa pre-remove
file is executed before removal of the package.
This file should be used to perform any required pre-removal steps or to display
notices.
.Ss post-install
The
.Pa post-install
file is executed after installation of the package.
This file
should be used to perform any required post-install steps or to display notices.

.Sh HISTORY
Originally, SHA256 was used as the checksum algorithm.
In September 2022, the checksums were switched to use BLAKE3 for speed
improvements.
