  • Problem comparing javascript files with long lines

    Hi.
    I'm noticing a problem when I merge two large (>100k) javascript files containing many scripts from different sources and some of the content is packed or compressed (jQuery) so a 50k library occupies just one line.

    I believe what happens is I get CRLF's at the end of every line so it looks ok after merging until I click the reload button and now I have extra blank lines for every-other line in that script. Once I copy over the changes to that section again (removing the extra linefeeds), everything is ok.

    Rick,

    BC defaults to wrapping long lines at 4096 characters. If lines in your files are longer than the default value, you'll need to increase it. To increase the value, select "Tools > File Formats" from the menu. Select the format for your files, then go to the Conversion tab. Increase the "characters per line limit" value to a value larger than your longest line.

      Thanks Chris.

      Looks like it's using "text format" rules for JS. Guess I'll have to create one for scripts.

      The length for that jQuery right now is 30777.

        Hello,

        Just make sure that file format is applied automatically by having it be the topmost file format in the Tools menu -> File Formats dialog with a matching file mask ("*.js;*.jscript"?)

        That way, it is also the file format that is applied by default for scripts whenever a rules-based comparison is used (for a report or folder compare rules-based comparison).

          Hi Aaron.

          I'm also having an issue with Source Integrity where it sees a 30+k line (jQuery again) and assumes the js file is a binary and I can't update or compare to the original file.

          Cutting the line lengths down to a more-normal size (adding LF in appropriate places) seems to fix both problems.

          FWIW, the online compaction using this page seems very good. Many of the ones I tested, just introduces JS errors.

            How large are your files? Would you be able to send a pair of sample files and your Support package (Help menu -> Support; Export) to [email protected] ?

            Please include a link to this forum post as well. Thanks.

            You may need to rename your files to .txt to get them past spam filters.
