2014-08-18gexp: Add 'ungexp-native' and 'ungexp-native-splicing'....* guix/gexp.scm (<gexp>)[natives]: New field. (write-gexp): Use both 'gexp-references' and 'gexp-native-references'. (gexp->derivation): Use both 'gexp-inputs' and 'gexp-native-inputs', and append them. (gexp-inputs): Add 'references' parameter and honor it. (gexp-native-inputs): New procedure. (gexp->sexp)[reference->sexp]: Add 'native?' parameter and honor it. Use it, and use 'gexp-native-references'. (gexp)[collect-native-escapes]: New procedure. [escape->ref]: Handle 'ungexp-native' and 'ungexp-native-splicing'. [substitute-ungexp, substitute-ungexp-splicing]: New procedures. [substitute-references]: Use them, and handle 'ungexp-native' and 'ungexp-native-splicing'. Adjust generated 'make-gexp' call to provide both normal references and native references. [read-ungexp]: Support 'ungexp-native' and 'ungexp-native-splicing'. Add reader extension for #+. * tests/gexp.scm (gexp-native-inputs): New procedure. (gexp->sexp*): Add 'target' parameter. ("ungexp + ungexp-native", "input list + ungexp-native", "input list splicing + ungexp-native-splicing", "gexp->derivation, ungexp-native", "gexp->derivation, ungexp + ungexp-native"): New tests. ("sugar"): Add tests for #+ and #+@. * doc/guix.texi (G-Expressions): Document 'ungexp-native' et al. Ludovic Courtès
2014-08-17gexp: Add #:target parameter to 'gexp->derivation'....* guix/gexp.scm (lower-inputs): Add #:system and #:target. Use 'package->cross-derivation' when TARGET is true. Honor SYSTEM. (gexp->derivation): Add #:target argument. Pass SYSTEM and TARGET to 'lower-inputs' and 'gexp->sexp'. (gexp->sexp): Add #:system and #:target. Pass them in recursive call and to 'package-file'. * tests/gexp.scm (gexp->sexp*): Add 'system' and 'target' parameters. ("gexp->derivation, cross-compilation"): New test. Ludovic Courtès
2014-07-17gexp: Gracefully handle printing of gexps with spliced references....* guix/gexp.scm (write-gexp): Wrap 'write' call in 'false-if-exception'. * tests/gexp.scm ("printer", "printer vs. ungexp-splicing"): New tests. Ludovic Courtès
2014-07-16gexp: Build 'gexp->file' derivations locally....* guix/gexp.scm (gexp->file): Add #:local-build? argument. Ludovic Courtès
2014-07-12gexp: Resolve the default system at '>>=' time....Partly fixes <http://bugs.gnu.org/18002>. Reported by David Thompson <dthompson2@worcester.edu>. * guix/gexp.scm (gexp->derivation): Change #:system to default #f. Use (%current-system) from within the 'mlet*'. * tests/gexp.scm ("gexp->derivation, default system"): New test. Ludovic Courtès
2014-06-04tests: Skip tests that would hit the shebang length limitation....* tests/gexp.scm (shebang): New variable. Skip "gexp->script" when SHEBANG is longer than 127 chars. * guix/gexp.scm (gexp->script): Add comment on the issue. Ludovic Courtès
2014-05-01monads, gexp: Remove unintended dependency on (gnu packages …)....* guix/gexp.scm (gexp->derivation, gexp->script): Use 'default-guile' instead of an explicit reference to 'guile-final'. (default-guile): New procedure. * guix/monads.scm (run-with-store)[default-guile]: New procedure. Use it. Ludovic Courtès
2014-05-01gexp: Add support for 'origin?' objects in 'ungexp' forms....* guix/gexp.scm (lower-inputs, gexp-inputs, gexp->sexp, canonicalize-reference): Add 'origin?' case. * guix/monads.scm (origin->derivation): New procedure. * tests/gexp.scm ("one input origin"): New test. Ludovic Courtès
2014-04-30gexp: Add pretty printer....* guix/gexp.scm (write-gexp): New procedure. <top level>: Add call to 'set-record-type-printer!'. Ludovic Courtès
2014-04-29gexp: Remove leftover parameter....* guix/gexp.scm (gexp->sexp): Remove #:outputs parameter. Adjust callers accordingly. Ludovic Courtès
2014-04-28monads: Hide 'derivation-expression' and 'lower-inputs'....* guix/monads.scm: Unexport 'lower-inputs' and 'derivation-expression'. (text-file*): Add comment about the switch to 'gexp->derivation'. (lower-inputs): Add comment about its doom. (derivation-expression): Likewise. * guix/gexp.scm (lower-inputs*): Rename to... (lower-inputs): ... this. Update callers. * tests/monads.scm (derivation-expression): New procedure. * doc/guix.texi (The Store Monad): Use 'gexp->derivation' instead of 'derivation-expression'. Remove documentation of 'derivation-expression'. * guix/ui.scm (read/eval): Use THE-ROOT-MODULE so that macros are properly expanded. * tests/guix-build.sh: Use 'gexp->derivation' instead of 'derivation-expression'.monads: Hide 'derivation-expression' and 'lower-inputs'. Ludovic Courtès
2014-04-28Add (guix gexp)....* guix/gexp.scm: New file. * tests/gexp.scm: New file. * Makefile.am (MODULES): Add guix/gexp.scm. (SCM_TESTS): Add tests/gexp.scm. * doc/guix.texi (Derivations): Add #:inputs in 'derivation' example. Mark 'build-expression->derivation' as deprecated, refer to "G-Expressions".
