Screenshot from krename showing bug
SUMMARY
krename is inserting unwanted white space in resulting filename when extracting
group of characters calculated from end of filename.
STEPS TO REPRODUCE
1. Run krename.
2. Run dolphin. Browse to a folder that contains *.jpg files to be renamed
using krename.
3. Per STRG+a select all image files, drag them into krename.
4. On all image files, using enhanced mode for file rename, rename all images
to include exif-time and -date, replace all ":" by "+" to have an extra
character to be recognizeable to distinguish date part from time part in an
extra renaming step.
6. Rename all files again by adding exif time and date part again, so resulting
image file names now have both "+" and ":" separated date and time parts.
Because we now have exif date and time included in file name twice it is now
possible to create a customized date string by replacing "+" by "-" and also
add time string keeping initial ":" as separators. Time string can be created
by taking last 8 characters of current resulting file name.
7. BUG: For testing purposes and showing bug: in this step I wanted to create
the final file name that was intended in the first place but I got stuck with
the bug. So here is a step to replicate the bug.
Create template string "dummy[$[#length-8]-[#length]]" and watch resulting file
names. This template should take the last 8 characters from end of filename, no
matter how long file name is.
OBSERVED RESULT
7. Some of the resulting filenames has time string extracted of input filename,
as intended. But then also a group of filenames (first half of list) has an
extra white space introduced (BUG).
EXPECTED RESULT
7. The extracted time tag should look like this: 12:01:15 which contains 8
characters that can be extracted by calculating #length-8 from initial file
name length and extracting 8 characters until end of file name. In all file
names this time tag is located at starting 8 characters beginning before end of
file name. The "dummy" word shows that the last approx. half group of filenames
was created correctly without a blank space between dummy and the two digits of
the hour. The approx. first half group of filenames has an extra blank space
between "dummy" and the two digits of the hour. This is BUG.
