Re: How to build with Alire

[Simon Wright]

You can use "alr edit", with some inconveniences.

It basically sets the environment as in "alr printenv" and then starts the 
editor in that environment.

I run the attached shell script; if the argument is "emacs", it configures "alr 
edit" to run a new copy of emacs; otherwise, GNATStudio.

Disadvantage: it opens emacs on the GPR, so you have to navigate to an Ada 
source before you can set the GPR as the one to use.

#!/bin/sh

case $1 in
    emacs)
        alr config --global --set editor.cmd 'open -n -a emacs ${GPR_FILE}'
        ;;
    *)
        alr config --global --set editor.cmd 'open -n -a gnatstudio -- 
${GPR_FILE}'
        ;;
esac

set-alr-edit.sh
