# format_commit.awk - format git commit id for inserting text_rom_init.mem
# awk used to format git commmit id into seven lines of a 12 bit mem file. ie:
# INPUT generated by: git rev-parse HEAD | head -c7 | basenc --base2msbf --wrap=8
# 01100100
# 01100110
# 00110001
# 00110010
# 01100101
# 01100100
# 00110111
# Run after checkout, before synthesis to embed commit into video overlay lower right corner
# git rev-parse HEAD | head -c7 | basenc --base2msbf --wrap=8 | awk -f format_commit.aw
#
# The 7 liens of output replace the lines 3833,+7 in the text_rom_init.mem
# upon checkout are: 0123abc
# 000000110000
# 000000110001
# 000000110010
# 000000110011
# 000001100001
# 000001100010
# 000001100011
