Working around #354 by manually creating the missing directories in result, JPlag finishes successfully.

That gives me:

$ ls -RF result
result:
2018-101/  overview.json

result/2018-101:
merged.cif-2018-102/

result/2018-101/merged.cif-2018-102:
merged.cif.json

No index.html to start viewing results, no instructions at the website. What next?

Guessing I need the report-viewer in some way:

$ cd report-viewer

$ npm install
npm install

We currently have not integrated the doc in the wiki yet, for now, you can refer to:
cholakov11#2, cholakov11#3, and cholakov11#4. If that does not help I refer to @sebinside.

From having a look at error log, this indicates that you must update your local NodeJS version (the current LTS version is 16.14).

ERROR  You are using Node v10.19.0, but vue-cli-service requires Node ^12.0.0 || >= 14.0.0.
        Please upgrade your Node version.

Besides that, npm install and npm run serve or npm run build should be sufficient. Alternatively, with every push to the main branch of JPlag, the report-viewer gets deployed to GitHub Pages.

In future versions, a bundle with all required files will be created also locally. We'll add this and also #354 to the task lists for the first release with the new viewer.

Many thanks!

As I have no idea what "updating NodeJS" means concretely, I opted for the deployed version that you linked to.

I created a zip with

$ unzip -l x.zip
Archive:  x.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
   175814  2022-04-07 13:57   m1.cif-m2.cif.json
      517  2022-04-07 13:57   overview.json
---------                     -------
   176331                     2 files

This is ok, as I just had 2 files, so one comparison.

I dropped the x.zip in the GH page, and it opened to an overview page stating 34% overlap.

Clicking at the top-right, and then manually opening both files gave me this (only the top part, as the files are long):

I can scroll both files up and down and left and right, but I couldn't see any indication of the 34% overlap.

I also noticed the display contracts eg >= to ≥. Cif however is a pure ASCII language, ≥ in the input will throw a parse error. I would suggest not to do that or make it a toggle option.

To do it correctly you would need the underlying token structure. Eg imagine a language where x<a>=17 is allowed syntax, X<a≥17 is something very different.

EDIT: Line numbers in both files are off-by-1, JPlag defines the first line as 1.

Yes, we currently use a version of JetBrains Mono that has such characters. This will be replaced in a future version. Also a good hint with the line numbers being off, I will add that to the (already quite long) list of changes that shall be done until version 4.

Regarding the display of overlaps: Have a look at the blue bar on the left side, there is a (currently not very visible, we're aware of that) view that gives you more information. However, it should also be visible in the code. Could you please investigate whether there are errors in the developer console (e.g., in chrome and edge on windows opened with ctrl + shift + J). We already discovered this display bug but did not find its cause yet.

I missed the left vertical bar as it had no ">>" signs on it. As a suggestion, perhaps also allow clicking at any other place at the bar (also for opening the files), Having to "precisely" click the signs is somewhat annoying.

I opened the web developer tools (firefox 99.0), mint-001 1.00 edition (part of the Linux Mint LTS 20 distribution). Just opening the GH page gacve the following error:

The bottom "went out of scope" error seems to happen when you move the mouse over and out the window (which then loses focus as my mouse defines the focus), so that is harmless I think.

I also have a long error when clicking (I think in the left file view). Top-part dump:

and bottom part (the "P" line is shown in both parts)

A similar long error happens when you click in the comparison window at the left (after opening it). Just the top part this time (looking at the error message again I now realize this image may be too short):

And last but not least, I noticed "-1" values in the latter view, which is wrong as I was pretty sure my scanner does produce line and column information :p
So I checked by dumping the 5 first tokens of each file, and at the bottom-right the first matched token in the comparison json file:

You can see the parse does produce the tokens with the information. Hacked Submission.java file:

// Line 171
        tokenList = language.parse(submissionRootFile, relativeFilePaths);
        System.out.printf("Parsed file %s, %d tokens%n", submissionRootFile.toString(), tokenList.size());
        for (int i = 0; i < 5 && i < tokenList.size(); i++) {
            System.out.printf("Token %d: %s%n", i, tokenList.getToken(i).toString());
        }
        System.out.printf("%n");

        if (!language.hasErrors()) {

Thank you for the detailed report, we'll have a look at it in #357.
