How to check if files committed to SVN is encoded in UTF-8 with pre-commit hooks?

i'm trying to write a SVN pre-commit hook script in Linux Bash that will reject a commit if the files can not be parsed as UTF-8.

So far I have written this script:

REPOS="$1"
TXN="$2"

SVNLOOK=/usr/bin/svnlook
ICONV=/usr/bin/iconv

# Make sure that all files to be committed are encoded in UTF-8

for FILE in $($SVNLOOK changed -t "$TXN" "$REPOS"); do
    if [$ICONV -f UTF-8 $FILE -o /dev/null]; then
        echo "Only UTF-8 files can be committed ("$FILE")" 1>&2
        exit 1
    fi

# All checks passed, so allow the commit.
exit 0

The problem is that iconv requires the path to the committed files (or the text in some other form), and I don't know how to get it.

Can anyone help?

Solution

  • Use svnlook cat to get the contents of a file from a transaction:

    $SVNLOOK cat -t "$TXN" "$REPOS" "$FILE"
