Given a FORMAT text that produces output in aligned columns makes it easy enough to meet the other requirements. To cause texts to be aligned left, append sufficient spaces to each output text, and for centred text, half that number. This relies on the special intrinsic function REPEAT(text,n) returning a varying number of characters - CHARACTER functions have to return a ''fixed'' number of characters, until the standardisation of varying-length strings in F2003 ''et seq''. Earlier Fortrans lack the REPEAT function, but its effect can be gained via something like CHARACTER*66 SPACE, where SPACE is set to spaces, and SPACE(1:N) is used where REPEAT(" ",N) is desired. And if messing with variable FORMAT is unwanted, the REPEAT scheme can be used for the right-justified output also.

SUBROUTINE RAKE(IN,M,X,WAY) !Casts forth text in fixed-width columns.

Collates column widths so that each column is wide enough for its widest member.

CALL RAKE(IN,M,"$",+1) !Align right.

END !That's all.

Every line of output starts with a space, and if it were to be sent to a lineprinter, this would be used as the carriage control character (meaning, advance one line then print the rest) - the first column does not need to be set off by one space from the previous column, but rather than devise special treatment it is spaced off anyway. The free-format output statements also start with a space. Output:

The following procedure solves the problem. It takes the string to be operated on as input, and an optional alignment parameter, which defaults to centred alignment. The aligned text is returned, as a string, which can then be printed.

AlignColumns := proc( txt, align :: { "left", "right", "centre" } := "centre" )

uses StringTools;

Join( J, "\n" )

end proc:

====Using f-strings====

print(' '.join(f"{wrd:{j}{wdth}}" for wdth, wrd in zip(widths, line)))

print("- " * 52)

====Using StringIO====

textinfile = '''Given$a$text$file$of$many$lines,$where$fields$within$a$line$

infile = StringIO(textinfile)

print "\n# %s Column-aligned output:" % align

 

{{out}}

Works with Python 2 and 3.

for row in rows:

print(' '.join(fmts).format(*(row + [''] * len(fmts))))

This is a draft implementation of the "align columns" problem using Unix shell commands. The key tool for left and right justified text is the "rs" command. Centered text is a little more complex, since this is not a feature currently in "rs" (''The centered solution will be added later.'')

Further, allow for each word in a column to be either left

justified, right justified, or center justified within its column.

 

The centered output will be added later, when I've more time. '' I did this in about 10 minutes.''

Note that the left-justified case can be handled trivially by the <tt>column</tt> command, which ships with modern Linux and macOS systems:

For right justification, each word's string of trailing blanks is moved to the beginning,

and for center justification, the trailing blanks are divided equally between the beginning and end of each word.

Blow apart the text into a list of words, find max len of any word, calc how many words will fit on a 80 col line, format all words into a bit bucket line at a time. Formatting is "%-ms" or "%ms" for left & right justify (m is field width), calculated for center. fmt is the string format method or center calc function, depending. Where string formatting can be used, it would be better to format all words in a line in one go but the code would be longer.
