Abbreviations, automatic

From Rosetta Code
Task
Abbreviations, automatic
You are encouraged to solve this task according to the task description, using any language you may know.

The use of   abbreviations   (also sometimes called synonyms, nicknames, AKAs, or aliases)   can be an
easy way to add flexibility when specifying or using commands, sub─commands, options, etc.


It would make a list of words easier to maintain   (as words are added, changed, and/or deleted)   if the minimum abbreviation length of that list could be automatically (programmatically) determined.


For this task, use the list (below) of the days-of-the-week names that are expressed in about a hundred languages   (note that there is a blank line in the list).

Caveat:   The list (above) most surely contains errors (or, at the least, differences) of what the actual (or true) names for the days-of-the-week.


To make this Rosetta Code task page as small as possible, if processing the complete list, read the days-of-the-week from a file (that is created from the above list).


Notes concerning the above list of words

  •   each line has a list of days-of-the-week for a language, separated by at least one blank
  •   the words on each line happen to be in order, from Sunday ──► Saturday
  •   most lines have words in mixed case and some have all manner of accented words and other characters
  •   some words were translated to the nearest character that was available to code page   437
  •   the characters in the words are not restricted except that they may not have imbedded blanks
  •   for this example, the use of an underscore (_) was used to indicate a blank in a word


Task
  •   The list of words   (days of the week)   needn't be verified/validated.
  •   Write a function to find the (numeric) minimum length abbreviation for each line that would make abbreviations unique.
  •   A blank line   (or a null line)   should return a null string.
  •   Process and show the output for at least the first five lines of the file.
  •   Show all output here.

Erlang[edit]

This example uses a byproduct of turning a list into a set. Only the unique elements are added to the set.

The output is of the set of abbreviations. These are not sorted correctly and some encoding errors remain.

uniq(_, L, Acc) ->
Abbr = [string:substr(X,1,Acc) || X <- L],
% list of abbrevs, starting with substring 1,1:
TempSet = sets:from_list( Abbr ),
TempSize = sets:size(TempSet),
if
TempSize =:= 7 ->
uniq(TempSet,Acc);
true -> uniq(0, L, Acc+1)
end.

Factor[edit]

Part of Factor's philosophy is to write extremely short words (functions). As a guideline, words should usually fit on one to three 64-column lines unless they use cond or contain a large literal. If you find yourself writing a word longer than that, it's time to factor!

As a concatenative language, Factor is uniquely suited for factoring words into smaller words. Assuming lexical/dynamic variables are not used, factoring is a cut-and-paste job that can be performed almost anywhere there is whitespace.

Nim[edit]

We have chosen to ignore the case as we considerer that in line Domingo Lunes martes Miercoles Jueves Viernes Sabado, the lower case 'm' for “martes” is a mistake and should not be considered to be relevant. This is different from the choice made by most other solutions

We provide two solutions, one consisting to build the abbreviations for each language and stopping when all of them are different, the second sorting the list of day names for each language and adjusting the abbreviation length to make sure that two consecutive day names are different. The second method should be more efficient, but it doesn’t really matters here.

Using a set[edit]

 
import sets
import unicode
 
type Runes = seq[Rune]
 
var linenum = 0
for line in lines("days.txt"):
inc linenum
if line.len > 0:
 
# Extract the day names and store them in a sorted list of sequences of runes.
var days: seq[Runes]
for day in line.splitWhitespace():
days.add(day.toLower.toRunes)
if days.len != 7:
echo "Wrong number of days at line ", linenum
 
# Build the abbreviations and store them in a set.
var index = 0
while true:
var abbrevs: HashSet[seq[Rune]]
for day in days:
abbrevs.incl(day[0..min(index, day.high)])
if abbrevs.card == 7:
# All abbreviations are different: fine!
break
inc index
echo index + 1, " ", line
 
else:
echo line
 

Using a sorted list[edit]

 
import algorithm
import unicode
 
type Runes = seq[Rune]
 
var linenum = 0
for line in lines("days.txt"):
inc linenum
if line.len > 0:
 
# Extract the day names and store them in a sorted list of sequences of runes.
var days: seq[Runes]
for day in sorted(line.toLower.splitWhitespace()):
days.add(day.toRunes)
if days.len != 7:
echo "Wrong number of days at line ", linenum
 
# Compare the first letters of successive day names, incrementing the upper index if necessary.
var index = 0 # Equal to abbreviation length - 1.
var prevday = days[0]
for idx in 1..days.high:
let currday = days[idx]
if currday == prevday:
echo "Double encountered at line ", linenum
while currday[0..min(index, currday.high)] == prevday[0..min(index, prevday.high)]:
inc index
prevday = currday
echo index + 1, " ", line
 
else:
echo line

Phix[edit]

The file abbrev_auto.txt was manually created from the task description. The following code assumes a more recent version of get_text() that strips any leading utf8 bom by default (0.8.0+).

constant lines = get_text("abbrev_auto.txt",GT_LF_STRIPPED)
 
for i=1 to length(lines) do
string li = lines[i]
if length(li) then
sequence days = split(li,no_empty:=true)
if length(days)!=7 then ?9/0 end if
integer len = 1
for j=1 to 7 do
for k=j+1 to 7 do
for m=1 to min(length(days[j]),length(days[k])) do
if days[j][m]!=days[k][m] then exit end if
len = max(len,m+1)
end for
end for
end for

Raku[edit]

(formerly Perl 6)

Works with: Rakudo version 2017.08

Saving the "Days of Week, Also Known As" table to a local file DoWAKA.txt. Lines that have duplicate day names will get ∞ as the minimum number of characters, as there is no amount of characters that can be entered to distinguish the days uniquely. It is somewhat unclear as to what is meant by "return a null string". I have chosen to return Nil.

Note that this is using a previous version of the date file that has erroneous duplicate day names (see line 90). Since the effort was already expended to catch such problems, it may as well be demonstrated.

sub auto-abbreviate ( Str $string ) {
return Nil unless my @words = $string.words;
return $_ if @words».substr(0, $_).Set == @words for 1 .. @words».chars.max;
return '∞';
}
 
# Testing
say ++$, ') ', .&auto-abbreviate, ' ', $_ for './DoWAKA.txt'.IO.lines;

zkl[edit]

zkl doesn't grok UTF-8 so I'm using a byte by byte check. It works surprisingly well.

nds:=File("daysOfWeek.txt").read().howza(11)	// stripped lines
.pump(List,Void.Filter,fcn(day){
d,N,m := day.split(),d.len(),(0).max(d.apply("len")); // N==7
foreach n in ([1..m]){
ds:=d.apply("get",0,n); // ("Su","Mo","Tu","We","Th","Fr","Sa")
foreach a,b in (N,[a+1..N-1]){ if(ds[a]==ds[b]) continue(3); } # Th==Fr?
return(n,day); // part way though the words and found unique
}
return(m,day); // no match nowhere
});
foreach n,s in (nds){ println("%3d  %s".fmt(n,s)); }
