(run-command): Remove call to 'call-with-temporary-output-file' and hop through Bash. Expect COMMAND to be a list of strings rather than a string. * gnu/installer/final.scm (install-system): Turn INSTALL-COMMAND into a list of strings and pass it to 'run-command'. * gnu/installer/newt/page.scm (edit-file): Likewise. Ludovic Courtès 2020-03-05installer: Implement a dialog on /var/guix/installer-socket....This will allow us to automate testing of the installer. * gnu/installer/utils.scm (%client-socket-file) (current-server-socket, current-clients): New variables. (open-server-socket, call-with-server-socket): New procedure. (with-server-socket): New macro. (run-shell-command): Add call to 'send-to-clients'. Select on both current-input-port and current-clients. * gnu/installer/steps.scm (run-installer-steps): Wrap 'call-with-prompt' in 'with-socket-server'. Call 'sigaction' for SIGPIPE. * gnu/installer/newt/page.scm (watch-clients!, close-port-and-reuse-fd) (run-form-with-clients, send-to-clients): New procedures.

Ludovic Courtès 2020-01-20installer: Disable F12 hot key....Fixes <https://bugs.gnu.org/38562>. Reported by Brice Waegeneire <brice@waegenei.re>. Previously, pressing F12 or shift-F2 in one of those forms would cause it to exit, usually with the default value #t because the caller had not provided a useful hotkey "callback". * gnu/installer/newt/page.scm (run-input-page, run-confirmation-page) (run-listbox-selection-page, run-checkbox-tree-page) (run-file-textbox-page): Pass #:flags FLAG-NOF12 to 'make-form'. Ludovic Courtès 2020-01-20installer: Makes sure the installer proceeds after hitting "Edit"....Fixes <https://bugs.gnu.org/39199>. Reported by Jonathan Brielmaier <jonathan.brielmaier@web.de>. * gnu/installer/newt/page.scm (run-file-textbox-page): Move 'loop' to the beginning of the body. Do not call 'loop' from the 'dynamic-wind' exit handler as we would not return the value of the second call to 'loop'. Ludovic Courtès 2020-01-12installer: Add an "Edit" button on the final page....Fixes <https://bugs.gnu.org/36885>. Reported by <lukasbf@tutanota.com>. * gnu/installer/newt/page.scm (edit-file): New procedure. (run-file-textbox-page): Add #:edit-button? and #:editor-locale parameters. Remove 'file-text' and add 'edit-button', and add it to the horizontal stacked grid when EXIT-BUTTON? is true. Wrap body in 'loop'. Handle case where ARGUMENT is EDIT-BUTTON by calling 'loop'. * gnu/installer/newt/final.scm (run-config-display-page): Add #:locale parameter. Pass #:edit-button? and #:editor-locale to 'run-file-textbox-page'. (run-final-page): Pass LOCALE to 'run-config-display-page'. Ludovic Courtès
