Script for translating comments in source files

I just created a script in order to translate the C-style comments (//) of a source file, with the aid from an external translation service, like Google Translate.

Steps to translate the comments of a source file:

1. Translate the file in Google Translate or other translation service
2. Copy the result of the translation to a new file
3. Check that there are no extra or removed lines. If so, align the original and translated files
4. Only one-line comments are supported. If there are blocks with C-style comments, preceed the comments in these lines with //
5. Execute:
   translate_comments.sh original_file translated_file

This will keep the code and everything as in the original file, and only the comments from the translated file.

The script is:

#!/bin/ksh

TMP1=`mktemp`
TMP2=`mktemp`

cat $1 | awk -F"//" '{print $1;}' > $TMP1
cat $2 | awk -F"//" '{if (NF > 1) print "//"$2; else print "";}' > $TMP2

awk -F"//" '{
while ((getline code < ARGV[1]) > 0)
{
getline comment < ARGV[2];
print code""comment;
}
}' $TMP1 $TMP2

rm $TMP1 $TMP2


The script is available for download at:
