svn命令行日志格式化

这里将svn的日志压缩合并成一行显示

svnlog(){
    svn log "$@" | awk -f <(cat <<EOF
#!/usr/bin/awk -f

# Convert the "svn log" output into a one liner format, which is easier to grep
# or use in scripts. Pipe "svn log" into this script

# When we get a line that starts with a revision number, put the data in variables
/^r[0-9]+/ {
    rev=\$1
    user=\$3
    date=\$5
    time=\$6
    lines=13
}

# Anything that isn't a revision line, a separator line or an empty line
# will be part of the commit message. Concatenate these into the comment variable
! (/^r[0-9+]/ || /^-+$/ || /^$/) {
  comment = comment \$0
}

# With every separator line, output what we stored before and reset the comment variable
# To skip the first line we also check if we've already stored a revision
/^-+$/ && rev {
   print rev " | " user " | " date " | " time " | " comment
   comment = ""
}
EOF
)
}
