[Buildroot] [PATCH 1/1] utils/check-package: add a check for the new spacing convention

[Yann E. MORIN <yann.morin.1998@free.fr>]

Heiko, All,

On 2020-02-05 22:22 +0100, Heiko Thiery spake thusly:
> The seperation of the fields in the hash file should be 2 spaces for

I was thinking about this one recently, but we still have too many
issues with it:

    $ make check-package 2>&1 |grep warnings\ generated
    2166 warnings generated
    1692 warnings generated
    2538 warnings generated
    1551 warnings generated
    796 warnings generated

So, we need to either wiat for all the hash filers to be fixed one by
one, or we need a mass conversion effort...

I did that conversion way back then, and it is trivial I think:

    $ find . -type f -name '*.hash' -print0 \
    |xargs -0 sed -r -i -e 's/^(md5|sha(1|224|256|384|512))[[:space:]]+([^[:space:]]+)[[:space:]]+(.+)$/\1  \3  \4/'

    $ git diff --stat
    [...]
     1793 files changed, 6298 insertions(+), 6298 deletions(-)

So I'm keeping your patch on the side for now...

Regards,
Yann E. MORIN.
