Words containing "the" substring

From Rosetta Code
Words containing "the" substring is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
Task

Using the dictionary   unixdict.txt,   search words containing "the" substring,
then display the found words (on this page).

The length of any word shown should have a length   >  11.

AppleScript[edit]

AppleScripters can tackle this task in a variety of ways. The example handlers below are listed in order of increasing speed but all complete the task in under 0.2 seconds on my current machine. They all take a file specifier, search string, and minimum length as parameters and return identical results for the same input.

Using just the core language — 'words': 

on wordsContaining(textfile, searchText, minLength)
    script o
        property wordList : missing value
        property output : {}
    end script
    
    -- Extract the text's 'words' and return any that meet both the search text and minimum length requirements.
    set o's wordList to words of (read (textfile as alias) as «class utf8»)
    repeat with thisWord in o's wordList
        if ((thisWord contains searchText) and (thisWord's length ≥ minLength)) then
            set end of o's output to thisWord's contents
        end if
    end repeat
    
    return o's output
end wordsContaining

Using just the core language — 'text items': 

on wordsContaining(textFile, searchText, minLength)
    script o
        property textItems : missing value
        property output : {}
    end script
    
    -- Extract the text's search-text-delimited sections.
    set astid to AppleScript's text item delimiters
    set AppleScript's text item delimiters to searchText
    set o's textItems to text items of (read (textFile as alias) as «class utf8»)
    set AppleScript's text item delimiters to astid
    
    -- Reconstitute any words containing the search text from the stubs at the section ends and
    -- the search text itself, returning any results which meet the minimum length requirement.
    set thisSection to beginning of o's textItems
    set sectionHasWords to ((count thisSection's words) > 0)
    considering white space
        repeat with i from 2 to (count o's textItems)
            set foundWord to searchText
            if (sectionHasWords) then
                set thisStub to thisSection's last word
                if (thisSection ends with thisStub) then set foundWord to thisStub & foundWord
            end if
            set thisSection to item i of o's textItems
            set sectionHasWords to ((count thisSection's words) > 0)
            if (sectionHasWords) then
                set thisStub to thisSection's first word
                if (thisSection begins with thisStub) then set foundWord to foundWord & thisStub
            end if
            if (foundWord's length ≥ minLength) then set end of o's output to foundWord
        end repeat
    end considering
    
    return o's output
end wordsContaining

Using a shell script: 

on wordsContaining(textFile, searchText, minLength)
    -- Set up and execute a shell script which uses grep to find words containing the search text
    -- (matching AppleScript's current case-sensitivity setting) and awk to pass those which
    -- satisfy the minimum length requirement.
    if ("A" = "a") then
        set part1 to "grep -io "
    else
        set part1 to "grep -o "
    end if
    set shellCode to part1 & quoted form of ("\\b\\w*" & searchText & "\\w*\\b") & ¬
        (" <" & quoted form of textFile's POSIX path) & ¬
        (" | awk " & quoted form of ("// && length($0) >= " & minLength))
    
    return paragraphs of (do shell script shellCode)
end wordsContaining

Using Foundation methods (AppleScriptObjC): 

use AppleScript version "2.4" -- OS X 10.10 (Yosemite) or later
use framework "Foundation"
use scripting additions

on wordsContaining(textFile, searchText, minLength)
    set theText to current application's class "NSMutableString"'s ¬
        stringWithContentsOfFile:(textFile's POSIX path) usedEncoding:(missing value) |error|:(missing value)
    -- Replace every run of non AppleScript 'word' characters with a linefeed.
    tell theText to replaceOccurrencesOfString:("(?:[\\W--[.'’]]|(?<!\\w)[.'’]|[.'’](?!\\w))++") withString:(linefeed) ¬
        options:(current application's NSRegularExpressionSearch) range:({0, its |length|()})
    -- Split the text at the linefeeds.
    set theWords to theText's componentsSeparatedByString:(linefeed)
    -- Filter the resulting array for strings which meet the search text and minimum length requirements,
    -- matching AppleScript's current case-sensitivity setting. NSString lengths are measured in 16-bit
    -- code units so use regex to check the lengths in characters.
    if ("A" = "a") then
        set filterTemplate to "((self CONTAINS[c] %@) && (self MATCHES %@))"
    else
        set filterTemplate to "((self CONTAINS %@) && (self MATCHES %@))"
    end if
    set filter to current application's class "NSPredicate"'s ¬
        predicateWithFormat_(filterTemplate, searchText, ".{" & minLength & ",}+")
    
    return (theWords's filteredArrayUsingPredicate:(filter)) as list
end wordsContaining

Test code for the task with any of the above: 

local textFile, output
set textFile to ((path to desktop as text) & "unixdict.txt") as «class furl»
-- considering case -- Uncomment this and the corresponding 'end' line for case-sensitive searches.
set output to wordsContaining(textFile, "the", 12)
-- end considering
return {count output, output}
Output:
{32, {"authenticate", "chemotherapy", "chrysanthemum", "clothesbrush", "clotheshorse", "eratosthenes", "featherbedding", "featherbrain", "featherweight", "gaithersburg", "hydrothermal", "lighthearted", "mathematician", "neurasthenic", "nevertheless", "northeastern", "northernmost", "otherworldly", "parasympathetic", "physiotherapist", "physiotherapy", "psychotherapeutic", "psychotherapist", "psychotherapy", "radiotherapy", "southeastern", "southernmost", "theoretician", "weatherbeaten", "weatherproof", "weatherstrip", "weatherstripping"}}

PHP[edit]

Plain English[edit]

To run:
Start up.
Put "c:\unixdict.txt" into a path.
Read the path into a buffer.
Slap a rider on the buffer.
Loop.
Move the rider (text file rules).
Subtract 1 from the rider's token's last. \newline
Put the rider's token into a word string.
If the word is blank, break.
If the word's length is less than 12, repeat.
If "the" is in the word, write the word on the console.
Repeat.
Wait for the escape key.
Shut down.

REXX[edit]

This REXX version doesn't care what order the words in the dictionary are in,   nor does it care what
case  (lower/upper/mixed)  the words are in,   the search for the substring   the   is   caseless.

It also allows the substring to be specified on the command line (CL) as well as the dictionary file identifier.


Programming note:   If the minimum length is negative,   it indicates to find the words   (but not display them),   and
only the display the count of found words. 

/*REXX program finds words that contain the substring "the" (within an identified dict.)*/

Works with: Smalltalk/X
'unixdict.txt' asFilename contents  
    select:[:word | (word size > 11) and:[word includesString:'the']]
    thenDo:#transcribeCR

if counting per word is required (which is overkill here, as there are no duplicates in the file), keep them in a bag: 

bagOfWords := Bag new.
'unixdict.txt' asFilename contents  
    select:[:word | (word size > 11) and:[word includesString:'the']]
    thenDo:[:word | bagOfWords add:word. word transcribeCR].

bagOfWords transcribeCR.
bagOfWords size transcribeCR

Note: #transcribeCR is a method in Object which says: "Transcript showCR:self".
