Separate alphabets and numbers

Question

A paragraph of text has numbers and alphabetic letters mixed. Your task is to separate the numbers to the left side and the alphabetic letters to the right side in the same order of each line.

Rules:

1. Numbers are plain integers; so no decimal point, and no negative/positive signs.
2. Numbers may or may not be contiguous, but whatever the case may be, they have to be pushed to left side in the same order.
3. Numbers may occur in between words.
4. The text contains only ASCII alphabetic letters and numbers, along with spaces, underscores, commas and dots.
5. The one who does this with minimum keystrokes (like vim macros) or least amount of bytes in case of scripting is the winner.

Example Text:

A word can have any number of text like 433884,
but all the numb89ers has to be moved left side 
but alph6abetical va9lues has to be pas46ted on right side.
The text might con4tain chara29cters s2huffled like hlep or dfeintino or even
meaningless1 words co43mbined togeth81er.

Expected output:

433884A word can have any number of text like ,
89but all the numbers has to be moved left side 
6946but alphabetical values has to be pasted on right side.
4292The text might contain characters shuffled like hlep or dfeintino or even
14381meaningless words combined together.

Answer 1

Retina, 14 bytes

O%$`\d|(.)
$#1

Try it online!

Explanation

O introduces a sorting stage. % tells Retina to apply the transformation to each line separately. $ tells it to sort the matches by the result of the specified substitution.

The regex itself is \d|(.) which either matches a digit, or anything else which is captured into group 1. This is substituted with $#1 which is the number of captures of group 1. That is, the sorting key for digits is 0 and the sorting key for everything else is 1. Since sorting in Retina is stable, this simply moves digits to the left and everything else to the right.

(turn (lore +<) |=(@ `tape`(welp (skid (trip +<) |=(@ !=(~ (rush +< nud)))))))

++lore splits a multi-line cord into a (list cord), (trip +<) turns it into a tape. ++skid seperates a list in two: one side where the function returns yes, one side where it returns no. Our function tries to parse the character with ++nud (numeric) and checks if it parses fully, and then we weld the two lists back together into a tape.

Answer 7

V, 12 bytes

òí¨Ä©¨ä©/²±
​

V, is an unfinished, 2D string based golfing language. Although it is unfinished, this program works as of commit 45, which was published last night, making this a competing answer. (Most of my previous V answers were non-competing.)

Note, the trailing newline is necessary, although this is due to a bug.

Explanation:

ò            #Recursively, do:
 í           #Substitute on every line
  ¨Ä©¨ä©/²±  #The following regex. 

¨Ä©¨ä©/²± expands into the vim regex:

:%s/\(\D\)\(\d\)/\2\1

which is a non-digit (\D) followed by a digit (\d), and swap them.

Since this is filled with gross unicode characters, here is a reversible hexdump:

$args[0]-split"`n"|%{($_-replace'\D')+($_-replace'\d')}

Due to the need to support multi-line input, we have to encapsulate our -replace statements with a loop and -split on newlines. Otherwise basically equivalent to the JavaScript solution.

Answer 16

Factor 61

[ "\n"split [ [ digit? ] partition [ write ] bi@ nl ] each ]

It's a naive approach.

"\n"split splits the string on top of the stack into lines. Then, for each line:

1. [ digit? ] partition splits each line into digits-only and non-digits-only
2. [ write ] bi@ outputs both, and nl prints a newline.

PS:

As a word 90 bytes (71 if you replace the-factorish-long-name with 1 letter):

: numbers-to-the-front ( s -- ) "\n"split [ [ digit? ] partition [ write ] bi@ nl ] each ;

GNU Sed, 28

Score includes +1 for -r option to sed.

:
s/([^0-9])([0-9])/\2\1/

Repeatedly switches one non-number character followed by one number character until no more substitutions are made.

Sadly sed regexes don't have \d or \D, so these have to be written out longhand.

Ideone.

Anonymous function taking a string and printing output. Loops over characters, adding them to the left l or right r buffers until it finds a newline, then it prints and empties buffers.
