Could I configure IntelliJ diff viewer/merge tool as external tools in tortoiseSVN?
Re-read Comparing files using intellij idea as a diff command line tool until there will come enlightenment in getting correct command-line
<IntelliJ IDEA launcher> diff <path to file1> <path to file2>
where
file1
is your local copy,file2
is the repository version.
for external diff for TortoiseSVN, there you have to use %base
(repository-side file) and %mine
(modified file in WC) variables as placeholders for compared files.
You addded nothing (nor command, nor parameters) into your command line, thus - got nothing
Answer
/path/to/idea diff %mine %base
If you want to configure the merge tool, use this configuration:
/path/to/idea merge %mine %theirs %base %merged
