I am also unable to see any green '*' marking any skill (except the crosstrained skill itself) with OS X tiles for sword skills on 0.13.1-28-g3517093, 0.13.0 (429a20e13a368), 0.12.0 (a35e613580ded6).

I also tested with console, same issue.

I debugged further; this issue is due to "if (crosstrain_other(m_sk, show_all))" returning false, and thus not placing the green * for the skill responsible for the crosstraining.

This change fixes the skill menu to correctly show the green *:

     for (unsigned int i = 0; i < crosstrain_skills.size(); ++i)
         if (you.skill(crosstrain_skills[i], 10, true)
-            <= you.skill(sk, 10, true) - CROSSTRAIN_THRESHOLD
-           && (you.skills[crosstrain_skills[i]] > 0 || show_zero))
+            <= you.skill(sk, 10, true) - CROSSTRAIN_THRESHOLD)
             return true;

And that's probably a bad idea, since there's actually a show_all boolean specifically for this:

      const bool show_all = skm.get_state(SKM_SHOW) == SKM_SHOW_ALL;

Which, if I read this right, is only enabled when the skill menu is set to show *all* skills, not just the ones available for training.

And sure enough, pressing '*' to change to "Show: all" results in the green * being displayed correctly.

So, when crafting an entry for the skill menu, the _bonus functions need to be provided show_all = true *rather than* whatever the skill menu's SHOW_ALL value is.

And so these two changes repair the skill menu to correctly indicate the source of crosstraining, without altering any of the actual skill code.

bh helped me repro this on webtiles, and |amethyst notes that it requires the source of the crosstraining (Slings, for instance) to be 0 (or less than 1, I think?).

antitrain_other() and crosstrain_other() are only used by the skillmenu, so they could be altered to do the right thing if needed.

my idea of adding , true breaks if Throwing is 2.0 and Slings is not available to train.

I tried to do this:

~            && (you.skills[crosstrain_skills[i]] > 0 || show_zero || you.skills[crosstra

But it turns out that you can't just call methods on a skill integer value (wishful thinking, fail).

The addition of a you.can_train test:

&& (you.skills[crosstrain_skills[i]] > 0 || you.can_train[crosstrain_skills[i]] || show_z

Fixes the issue correctly for every test I've come across so far (Long 2.1, Short 0.0, carrying or not a short sword).

|amethyst is working out a patch that moves this crosstrain_other() function, which is only used by the skill menu, into the code to make better use of the 'should I show a skill or not' function for this. That's beyond my skill level, but I agree anyways :)

Fixed in trunk (0.14-a0-2993-g1142d79), thanks! I'm not sure if my refactoring really was an improvement though :/
