How to get $this->translate('Content') => Content in a Textfile

Question

I am looking for a shell script which scans a direcotry and all its subdirectories for .php and .phtml files. Within these files, I am looking for $this->translate('') statements (also $this->view->translate('')) and I want to save the content of these statements in a textfile.

The problem is, that there are several different types of this statements:

• $this->translate('Single Quotes') // I need: Single Quotes
• $this->translate("Double Quotes") // I need: Double Quotes
• $this->translate('Single quotes with %1$s placeholders', $xy) // I need: Single quotes with %1$s placeholders
• $this->translate("Double quotes with %1\$s", $xy) // I need: Dobule quotes with %1$s
• $this->view->translate('With view') // I need: With view
• $this->view->translate("With view 2") // I need: With view 2
• $this->translate('Single Quotes with "Doubles"') // I need: Single Quotes with "Doubles"
• $this->translate("Double Quotes with 'Singles') // I need: Double Quotes with 'Singles'

I have already programmed a script and a guy from starmind.com sent me the following lines:

 echo -n > give_me_your_favorite_outfile_name.txt

for i in `find . -iname '*php' `
do
    echo -n "Processing $i ..."
#    echo  "    +++++++ from $i ++++++++" >> give_me_your_favorite_outfile_name.txt
   cat $i | sed -n -e '/->translate(*/p' | sed -e 's/\(.*->translate(.\)\([a-z A-Z \d092\d039\d034]*\)\(.*\)/\2/g' | sed -e 's/\(.*\)\(\d039\)/\1/g' | sed -e 's/\(.*\)\(\d034\)/\1/g' >> give_me_your_favorite_outfile_name.txt
    echo " done"
done

for i in `find . -iname '*phtml' `
do
    echo -n "Processing $i ..."
#    echo "    +++++++ from $i ++++++++" >> give_me_your_favorite_outfile_name.txt
    cat $i | sed -n -e '/->translate(*/p' | sed -e 's/\(.*->translate(.\)\([a-z A-Z \d092\d039\d034]*\)\(.*\)/\2/g' | sed -e 's/\(.*\)\(\d039\)/\1/g' | sed -e 's/\(.*\)\(\d034\)/\1/g' >> give_me_your_favorite_outfile_name.txt
    echo " done"
done

Unfortunately, it does not cover all the above cases, especially the Quotes within Quotes cases. As I am not a shell expert at all and need that script for a verification process, I would be very happy to get help from you guys.

Important: It has to be written in Shell. A PHP Version exists.

find /path -type f \( -name "*.php" -o -name "*.phtml" \) | while IFS= read -r -d $'\0' file
 do
    while read -r line
    do
    case "$line" in
        *'$this->translate'* | *'$this->view->translate'* )
        line="${line#*this*translate(}"
        line="${line%%)*}"
        case ${line:0:1} in
            \$) s=${line:0};;
             *) s=${line:1:${#line}-2};;
        esac
        case "$s" in
           *[\"\'],* )
            s=${s/\\/}
            echo ${s%%[\"\'],*};;
           * ) echo "$s";;
        esac
    esac
    done < "$file"
 done

Answer 2

This does it using sed in a Bash while loop and demonstrates another way to do the find for variety's sake:

find . -iregex ".*\.php\|.*\.phtml" |
    while read f
    do
        sed -n '/[\"\o047]/ {s/$this->\(view->\|\)translate([\"\o047]\(.*\)[\"\o047].*)/\2/; s.\\..;p}' $f
    done > outputfile.txt

Edit:

To take care of other text on the line change the sed command to this:

sed -n '/[\"\o047]/ {s/.*$this->\(view->\|\)translate([\"\o047]\(.*\)[\"\o047].*).*/\2/; s.\\..;p}' $f

(Just add a .* at the beginning and end of the search string.)
