Right justify amounts in hledger journal text file-CodePudding

I have a text file and I'm trying to right-align / justify the amounts (123.00 EUR) to a specified column number (say 53) by stretching the spaces before them appropriately

The output should be

It could probably be done with awk or printf or something but I can't figure it out.

Using jq:

jq --raw-input --raw-output --argjson alignToColumn 53 '
  "\\d \\.?\\d*\\s EUR" as $searchPattern |   # regular expression to search for in each line
  if test($searchPattern)                     # test if line contains "xxxxx.xx EUR"
  then match($searchPattern) as $match |      # match "xxxxx.xx EUR"
       sub($searchPattern;
           " " * ($alignToColumn - $match.offset - $match.length)     # add leading spaces to matched "xxxxx.xx EUR"
           $match.string)
  else .                                      # no match found in line
  end
' file.txt

Remark

If a line contains more then one "xxxxx.xx EUR", the first match is aligned (see extra line "other stuff" in the output below)

According to hledger's manual, the field separator seems to be two or more spaces.

You should be able to use it for picking up the lines that contain an account and an amount.

Here's an awk idea for re-indenting the whole file with a given number of space characters while right-aligning the amounts:

awk -F ' {2,}|^  ' -v OFS='    ' '
    FNR == NR {
        if ( $1 !~ /^;/ ) {
            if ( NF >= 2 && $2 !~ /^;/ ) {
                account_size[FNR] = length($2)
                if ( max_account_size < account_size[FNR] )
                    max_account_size = account_size[FNR]
                if ( NF >= 3 && $3 !~ /^;/ ) {
                    amount_size[FNR] = length($3)
                    if ( max_amount_size < amount_size[FNR] )
                        max_amount_size = amount_size[FNR]
                }
            }
        }
        next
    }
    FNR in account_size {
        $2 = (FNR in amount_size) ? sprintf("%-" max_account_size   (max_amount_size - amount_size[FNR]) "s", $2) : $2
    }
    1
' file.txt file.txt

^{note: it's a two-pass algorithm so you need to provide the file twice}

^{remark: as you can see, the ; Bank fee comment was also indented with OFS}

Using GNU awk for the 3rd arg to match:

$ cat tst.awk
match($0,/^([[:space:]] [^[:space:]] )[[:space:]] ([0-9.]  [[:upper:]] )(.*)/,a) {
    $0 = sprintf("%-39s s%s", a[1], a[2], a[3])
}
{ print }

$ awk -f tst.awk file
