The effect is visible on commands like:
guix build -e '(+ 2 "foo")'
guix build -e '()'
* guix/ui.scm (read/eval): Change handler to properly report syntax errors and
use 'display-error' for other errors.
* guix/ui.scm (load*): Add #:on-error parameter.
[tag, error-string]: New variables.
Wrap 'load' call in 'call-with-prompt'. Pass TAG to 'make-stack'. Honor
ON-ERROR after 'report-load-error' call.
(report-load-error): Change to not exit on error. Make private.
* guix/scripts/system.scm (show-help, %options): Add --on-error.
(guix-system): Use 'load*' and pass it #:on-error.
Reported by Christian Grothoff.
* guix/ui.scm (load*): Add 'frame-with-source'. Set
%load-should-auto-compile. Change error handle to just (exit 1). Add
pre-unwind handler to capture the stack and call 'report-load-error'.
(report-load-error): Add optional 'frame' parameter and pass it to
'display-error'.
* tests/guix-system.sh: Add "unbound variable" test.
* guix/ui.scm (make-user-module, load*): New procedures.
* guix/scripts/system.scm (%user-module): Define in terms of
'make-user-module'.
(read-operating-system): Define in terms of load*'.
* guix/ui.scm (warn-about-load-error): New procedure.
* gnu/packages.scm (package-modules): Wrap 'resolve-interface' call in
'catch #t', and call 'warn-about-load-error' in handler.
* guix/scripts/system.scm (read-operating-system): Replace error
handling code by a call to 'report-load-error'.
* guix/ui.scm (report-load-error): New procedure.
Reported by Alex Kost <alezost@gmail.com>
at <http://lists.gnu.org/archive/html/guix-devel/2015-02/msg00702.html>.
* guix/ui.scm (parse-command-line)[parse-options-from]: Add 'seeds'
parameter.
Thread the result of the first 'parse-options-from' call to the
second.
Fixes <http://bugs.gnu.org/19630>.
Reported by Ricardo Wurmus <ricardo.wurmus@mdc-berlin.de>.
* guix/derivations.scm (&derivation-error,
&derivation-missing-output-error): New error conditions.
(derivation->output-path): Raise a '&derivation-missing-output-error'
if OUTPUT is not an output of DRV.
* guix/ui.scm (call-with-error-handling): Add case for
'derivation-missing-output-error?'.
(show-what-to-build): Check whether (derivation-outputs drv) is
empty.
* tests/packages.scm ("reference to non-existent output"): Add test.
* guix/ui.scm (report-error): Export.
* guix/scripts/system.scm (read-operating-system): Report syntax errors
using standard GNU format. Report other errors using 'display-error'.
This makes 'guix environment PACKAGE' significantly faster when
substitutes are enabled. Before that, it would lead to many invocations
of 'guix substitute-binary', one per 'derivation-prerequisites-to-build'
call. Now, all these are replaced by a single invocation.
* guix/derivations.scm (derivation-output-paths, substitution-oracle):
New procedures.
(derivation-prerequisites-to-build): Replace #:use-substitutes? with
#:substitutable?. Remove the local 'derivation-output-paths' and
'substitutable?'.
* guix/ui.scm (show-what-to-build): Add 'substitutable?'. Pass it to
'derivation-prerequisites-to-build'.
[built-or-substitutable?]: Use it instead of 'has-substitutes?'.
* tests/derivations.scm ("derivation-prerequisites-to-build and
substitutes"): Use #:substitutable? instead of #:use-substitutes?.
* guix/ui.scm (size->number): Add a bunch of large units. Recognize
one-letter unit names. Change "KB" to "kB".
* tests/ui.scm ("size->number, 1T"): New test.
* doc/guix.texi (Invoking guix gc): Add cross-reference to "Block size"
in the Coreutils manual.
(Invoking guix system): Likewise.
Previously 'guix pull' would just fail with "No such file or directory"
if ~/.config didn't already exist.
* guix/ui.scm (config-directory): Use 'mkdir-p' instead of 'mkdir'.
Change the 'catch' handler to expect errors different from EEXIST.
Fixes <http://bugs.gnu.org/17468>.
* guix/ui.scm (fill-paragraph): Two spaces after period and no spaces before newline.
* tests/ui.scm: New test case.
