;; Commentary:
;;
;; System for building packages that don't require much compilation, mostly
;; only to copy files around.
;;
;; Code:
(define* (install #:key install-plan outputs #:allow-other-keys)
"Copy files from the \"source\" build input to the \"out\" output according to INSTALL-PLAN.
An install plan is a list of plans in the form:
(SOURCE TARGET [FILTERS])
In the above, FILTERS are optional.
- When SOURCE matches a file or directory without trailing slash, install it to
TARGET.
- If TARGET has a trailing slash, install SOURCE basename beneath TARGET.
- Otherwise install SOURCE as TARGET.
- When SOURCE is a directory with a trailing slash, or when FILTERS are used,
the trailing slash of TARGET is implied.
- Without FILTERS, install the full SOURCE _content_ to TARGET.
The paths relative to SOURCE are preserved within TARGET.
- With FILTERS among `#:include`, `#:include-regexp`, `#:exclude`,
`#:exclude-regexp`:
- With `#:include`, install only the paths which suffix exactly matches
one of the elements in the list.
- With `#:include-regexp`, install subpaths matching the regexps in the list.
- The `#:exclude*` FILTERS work similarly. Without `#:include*` flags,
install every subpath but the files matching the `#:exlude*` filters.
If both `#:include*` and `#:exclude*` are specified, the exclusion is done
on the inclusion list.
Examples:
- `(\"foo/bar\" \"share/my-app/\")`: Install bar to \"share/my-app/bar\".
- `(\"foo/bar\" \"share/my-app/baz\")`: Install bar to \"share/my-app/baz\".
- `(\"foo/\" \"share/my-app\")`: Install the content of foo inside \"share/my-app\",
e.g. install \"foo/sub/file\" to \"share/my-app/sub/file\".
- `(\"foo/\" \"share/my-app\" #:include (\"sub/file\"))`: Install only \"foo/sub/file\" to
\"share/my-app/sub/file\".
- `(\"foo/sub\" \"share/my-app\" #:include (\"file\"))`: Install \"foo/sub/file\" to
\"share/my-app/file\"."
