.mk files: bulk aligment and whitespace cleanup of assignments The Buildroot coding style defines one space around make assignments and does not align the assignment symbols. This patch does a bulk fix of offending packages. The package infrastructures (or more in general assignments to calculated variable names, like $(2)_FOO) are not touched. Alignment of line continuation characters (\) is kept as-is. The sed command used to do this replacement is: find * -name "*.mk" | xargs sed -i \ -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#' -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#' -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#' -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#' Brief explanation of this command: ^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line \([?:+]\?=\) any assignment character =, :=, ?=, += \([^\\]\+\) any string not containing a line continuation \([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a line continuation character \(\s*\\\) optional whitespace, followed by a line continuation character Hence, the first subexpression handles empty assignments, the second handles regular assignments, the third handles regular assignments with line continuation, and the fourth empty assignments with line continuation. This expression was tested on following test text: (initial tab not included) FOO = spaces before FOO = spaces before and after FOO = tab before FOO = tab and spaces before FOO = tab after FOO = tab and spaces after FOO = spaces and tab after FOO = \ FOO = bar \ FOO = bar space \ FOO = \ GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse FOO += spaces before FOO ?= spaces before and after FOO := FOO = FOO = FOO = FOO = $(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C AT91BOOTSTRAP3_DEFCONFIG = \ AXEL_DISABLE_I18N=--i18n=0 After this bulk change, following manual fixups were done: - fix line continuation alignment in cegui06 and spice (the sed expression leaves the number of whitespace between the value and line continuation character intact, but the whitespace before that could have changed, causing misalignment. - qt5base was reverted, as this package uses extensive alignment which actually makes the code more readable. Finally, the end result was manually reviewed. Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Cc: Yann E.
