It looks like file discovery works incorrectly and is getting the path from the root where thecoomand was executed

@akuleshov7 are you sure you have the src/foo.eo file available? I just did what you are doing and it seems to work for me:

$ mkdir src
$ cat > src/foo.eo
[x] > foo
  div. > @
    42
    x
$ java -jar /code/polystat/polystat/target/polystat-1.0-SNAPSHOT-jar-with-dependencies.jar src temp
Error: \perp at {x=0, κ-4-3=\any}

This is where the location of the .eo file is being resolved: https://github.com/polystat/polystat/blob/master/src/main/java/org/polystat/Program.java#L80 Should work on both Unix and Windows.

@pollyvolk please check this out.

@mximp Could you, please, describe current requirements for the option --files?

According to the option description in Polystat.java, the value of this option specifies a directory with EO files. However, as mentioned in README, the program processes a single file called test.eo ignoring other .eo files.
If a user specifies, e.g., --files sources, but the folder sources doesn't contain test.eo, Polystat will throw an error.

Other case: a user runs Polystat with --files sources --tmp result, and there is a file sources/test.eo. The result of the analysis will be saved to result/test.xml. If the user renames or deletes the file sources/test.eo and runs the same command again, Polystat will print the previous correct result, taking it from result/test.xml, not throwing an exception.

Is it the functionality you expect to have?

[mximp]

@pollyvolk The second case is incorrect behaviour: if source is deleted the temp file should be deleted as well.

Regarding test files: current implementation supports only single object within sources named test.
This needs to be enhanced (we even have several requests for this feature) so that all .eo files are processed.

[pollyvolk]

@mximp Do you want me to fix the second case, as it is a wrong behaviour?

[mximp]

@pollyvolk yes please.

For the sources we already have issues: #58, #18, #17
