[runlisp] / runlisp-base.conf

;;; -*-conf-windows-*-

;; This file contains essential definitions for `runlisp'.  You are
;; encouraged to put your local changes in the main `runlisp.conf', or in
;; other files alongside this one in `runlisp.d/', rather then editing this
;; file.

;; Summary of syntax.
;;
;; Sections are started with a line `[NAME]', starting in the leftmost
;; column.  Empty lines and lines starting with `;' -- /without/ preceding
;; whitespace -- are ignored.  Assignments have the form `VAR = VALUE'; the
;; VALUE may be continued across multiple lines, if they begin with
;; whitespace.  All of the lines are stripped of initial and final whitespace
;; and concatenated with spaces.
;;
;; Values may contain substitutions:
;;
;;   * ${[SECTION:]VAR[?ALT]} -- replace with the value of VAR in SECTION; if
;;     not found, use ALT instead.  (If ALT isn't provided, it's an error.)
;;
;;   * $?[SECTION:]VAR{YES[|NO]} -- look up VAR in SECTION (or in the
;;     (original) current section, and `@COMMON'); if found, use YES,
;;     otherwise use NO.
;;
;; Variables are looked up starting in the home (or explicitly specified)
;; section, then proceeding to the parents assigned to `@PARENTS'.
;; (`@PARENTS' usually defaults to `@COMMON'; the parent of `@COMMON' is
;; `@BUILTIN'; `@BUILTIN' and `@CONFIG' have no parents.)
;;
;; At top-level, the text is split into words at whitespace, unless prevented
;; by double- and single-quote, or escaped by `\'.  Within single quotes, all
;; characters are treated literally.  Within double quotes, `\' and `$' still
;; works.  A variable reference within quotes, or within a word, suppresses
;; word-splitting and quoting, within the variable value -- but `$'
;; expansions still work.

;; Turn `#!' into a comment-to-end-of-line.  This is used in all Lisp
;; invocations, even though some of them don't apparently need it.  For
;; example, SBCL ignores an initial line beginning `#!' as a special feature
;; of its `--script' option.  Other Lisps won't do this, so a countermeasure
;; like the following is necessary in their case.  For the sake of a
;; consistent environment, we ignore `#!' lines everywhere, even in Lisps
;; which have their own, more specific, solution to this problem.

[clisp]

;; CLisp causes much sadness.  Superficially, it's the most sensible of all
;; of the systems supported here: you just run `clisp SCRIPT -- ARGS ...' and
;; it works.
;;
;; The problems come when you want to do some preparatory work (e.g., load
;; `asdf') and then run the script.  There's a `-x' option to evaluate some
;; Lisp code, but it has three major deficiencies.
;;
;;   * It insists on printing the values of the forms it evaluates.  It
;;     prints a blank line even if the form goes out of its way to produce no
;;     values at all.  So the whole thing has to be a single top-level form
;;     which quits the Lisp rather than returning.
;;
;;   * For some idiotic reason, you can have /either/ `-x' forms /or/ a
;;     script, but not both.  So we have to include the `load' here
;;     explicitly.  I suppose that was inevitable because we have to inhibit
;;     printing of the result forms, but it's still a separate source of
;;     annoyance.
;;
;;   * The icing on the cake: the `-x' forms are collectively concatenated --
;;     without spaces! -- and used to build a string stream, which is then
;;     assigned over the top of `*standard-input*', making the original stdin
;;     somewhat fiddly to track down.
;;
;; There's a `-i' option which will load a file without any of this
;; stupidity, but nothing analogous for immediate expressions.

[abcl]

;; CLisp made a worthy effort, but ABCL still manages to take the prize.
;;
;;   * ABCL manages to avoid touching the `stderr' stream at all, ever.  Its
;;     startup machinery finds `stdout' (as `java.lang.System.out'), wraps it
;;     up in a Lisp stream, and uses the result as `*standard-output*' and
;;     `*error-output*' (and a goodly number of other things too).  So we
;;     must manufacture a working `stderr' the hard way.
;;
;;   * There doesn't appear to be any easy way to prevent toplevel errors
;;     from invoking the interactive debugger.  For extra fun, the debugger
;;     reads from `stdin' by default, so an input file which somehow manages
;;     to break the script can then take over its brain by providing Lisp
;;     forms for the debugger to evaluate.
;;
;;   * And, just to really top everything off, ABCL's `adjoin.lisp' is
;;     missing an `(in-package ...)' form at the top, so it leaks symbols
;;     into the `COMMON-LISP-USER' package.
