| dnl Shell is hard, so here is what the following does: |
| dnl - Reset $@ (command line arguments) |
| dnl - Add the configure options from mozconfig to $@ one by one |
| dnl - Add the original command line arguments after that, one by one |
| dnl |
| dnl There are several tricks involved: |
| dnl - It is not possible to preserve the whitespaces in $@ by assigning to |
| dnl another variable, so the two first steps above need to happen in the first |
| dnl iteration of the third step. |
| dnl - We always want the configure options to be added, so the loop must be |
| dnl iterated at least once, so we add a dummy argument first, and discard it. |
| dnl - something | while read line ... makes the while run in a subshell, meaning |
| dnl that anything it does is not propagated to the main shell, so we can't do |
| dnl set -- foo there. As a consequence, what the while loop reading mach |
| dnl environment output does is output a set of shell commands for the main shell |
| dnl to eval. |
| dnl - Extra care is due when lines from mach environment output contain special |
| dnl shell characters, so we use ' for quoting and ensure no ' end up in between |
| dnl the quoting mark unescaped. |
| dnl Some of the above is directly done in mach environment --format=configure. |
