Use module (srfi srfi-13). Export `use2dot'. (string-append/separator, mapconcat): Delete. (vv): Now take list of pairs, and return the mapping.. (>>header): Use `string-join'. (>>): New proc. (use2dot): Use `getopt-long'. Use `>>'.

|
;; Usage: use2dot [OPTIONS] [FILE ...]
|
|
;; Display to stdout a DOT specification that describes module dependencies
|
|
;; in FILEs.
|
|
;;
|
|
;; A top-level `use-modules' form or a `:use-module' `define-module'-component
|
|
;; results in a "solid" style edge.
|
|
;;
|
|
;; An `:autoload' `define-module'-component results in a "dotted" style edge
|
|
;; with label "N" indicating that N names are responsible for triggering the
|
|
;; autoload. [The "N" label is not implemented.]
|
|
;;
|
|
;; A top-level `load' or `primitive-load' form results in a a "bold" style
|
|
;; edge to a node named with either the file name if the `load' argument is a
|
|
;; string, or "[computed in FILE]" otherwise.
|
|
;;
|
|
;; Options:
|
|
;; -m, --default-module MOD -- Set MOD as the default module (for top-level
|
|
;; `use-modules' forms that do not follow some
|
|
;; `define-module' form in a file). MOD should be
|
|
;; be a list or `#f', in which case such top-level
|
|
;; `use-modules' forms are effectively ignored.
|
|
;; Default value: `(guile-user)'.
