Merge lp:~tapaal-contributor/tapaal/cpn-gui-dev into lp:tapaal

[Kenneth Yrke Jørgensen]

Proposal of complete colored GUI including: Colortypes, variables, arc expression and colored arc intervals menu, guard expression menu, place and colored invariant menu, verification of colored nets and unfolding of colored nets.

To use all the features described in: https://docs.google.com/document/d/1SdUufTr0giizD-ZJ7BH0rcke-QQ-tp2MXfqb4c18sV8/edit

you will need verifydtapn with colors: https://github.com/TAPAAL-Developers/verifydtapn/tree/unfoldColor (PR: https://github.com/TAPAAL/verifydtapn/pull/10)
(Org branched from https://github.com/PeterHaahrTaankvist/verifydtapn/tree/unfolding_library)

and verifypn with colors: https://code.launchpad.net/~tapaal-contributor/verifypn/update-parser

I added a milestone for specifically to track bugs, so that we can keep the log in the pull request for code specific changes.

When creating a new bug related to the CPN branch, select the milestone TAPAAL CPN, this way we can easly filter bugs related to the branch, use this link: https://bugs.launchpad.net/tapaal/+bugs?field.searchtext=&orderby=-importance&field.status%3Alist=NEW&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.status%3Alist=FIXCOMMITTED&field.status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=INCOMPLETE_WITHOUT_RESPONSE&assignee_option=any&field.assignee=&field.bug_reporter=&field.bug_commenter=&field.subscriber=&field.structural_subscriber=&field.milestone%3Alist=93479&field.tag=&field.tags_combinator=ANY&field.has_cve.used=&field.omit_dupes.used=&field.omit_dupes=on&field.affects_me.used=&field.has_patch.used=&field.has_branches.used=&field.has_branches=on&field.has_no_branches.used=&field.has_no_branches=on&field.has_blueprints.used=&field.has_blueprints=on&field.has_no_blueprints.used=&field.has_no_blueprints=on&search=Search

All code only comments should be removed, unless it directly relates to something being explained.
Or if used for specialized debug. If for debug, please mark the beginning of block with DEBUG.

Internal members not mutated should be marked final.

(I will make a patch that fixes these to issues)

[Kenneth Yrke Jørgensen (yrke)]

File: ColoredArcGuardPanel.java
Function deleteSelections(), line 752

This "if" seems to have an flow error:

if (currentSelection.getObject() instanceof ArcExpression) {
    replacement = getSpecificChildOfProperty(1, currentSelection.getObject());
}
else if (currentSelection.getObject() instanceof ArcExpression) {
    replacement = new PlaceHolderColorExpression();
}

Second branch can't be reached, as it has the same guad as first branch. This must be a logical error.

[Kenneth Yrke Jørgensen (yrke)]

I noticed there seem to be a lot of TODO comments related to how colors should be handled.
I guess theses should all be adresse and can be removed safely?

If we leave in TODO comments for stuff that is already implemented or adresse elsewhere it can lead to confusion when we later revisit the code, as it might not be clear that the TODO comment is handled.

Intellij has a feature to list all todo/fixme etc. If there really is a todo, please add details about what is missing.

[Kenneth Yrke Jørgensen (yrke)]

It seems some shortcuts are updated, please remember to update documentation: https://github.com/TAPAAL/TAPAAL/wiki/Shortcut-keys

[Kenneth Yrke Jørgensen (yrke)]

I added a few more test to test out the api for new colors. I found a few problems in the interal consistency. Could you please have a look at this.
