Implement a better way to wrap text containing color tags

[db48x]

Summary

Interface "Improved text wrapping in spellbook and spellcasting menus"

Purpose of change

Long strings that need to wrap onto multiple lines and also contain color codes are hard to wrap correctly. This gets us most of the way to a correct solution.

It also lets us draw text with fewer allocations, allowing us to gradually get away from creating strings with color tags only to throw them away.

Fixes #77297
Also Fixes #76298
Also fixes #75901

Testing

Best place to test it is in the spellcasting window, using psi abilities. These frequently include color.

Additional context

This isn’t a perfect solution. It relies on ImGui’s built‐in text wrapping in several significant ways, and this comes at the cost of some remaining imperfections. Luckily these imperfections are less intrusive than the existing problems, and we can fix them as we have time and inclination.

[db48x]

Oops. Dumb mistake; I probably should have just left it until the morning when I could think more clearly.

[Night-Pryanik]

Should this also fix #75901?

[db48x]

It does; good catch. Weirdly I've never actually seen that bug report. I wonder how many more there are that I haven’t noticed because they don’t use the correct keywords.

[db48x]

Looks like a spurious build failure to me.

[CLIDragon]

I would appreciate documenting that BeginRightAlign requires calling EndRightAlign if it succeeds.

You mention that this leaves remaining imperfections - what are they?

[db48x]

Perhaps the most obvious flaw is that at certain wrap widths the first word of a segment will not be word–wrapped but instead will be split across two lines. This is due to a design decision to allow text rendering to make progress even if ImGui is asked to render it in a space too narrow for a whole word.

Fixing this is doable but not a high priority at the moment. The fix involves duplicating the ImGui methods that we currently call and tweaking their implementation. We could of course just modify ImGui directly, but that makes upgrading more difficult. Because we don't currently allow the user to resize any ImGui windows it’ll probably never actually come up.

There is also a really funny–looking problem that happens when a paragraph contains embedded newlines. Getting the correct rendering in that case merely requires the caller to split their strings if they contain any newlines. This is no great hardship, but I would prefer the API to handle it more gracefully. Fixing this is again doable, and again it’ll need to be done by duplicating and tweaking some of the ImGui methods that we call.

[db48x]

@kevingranade, is there anything else that needs to be done before this can be merged?

That’s weird. You can see that it is running the linker to build the executable, and that obj/tiles/third-party/imgui/imgui.o is listed twice.

[db48x]

I cannot reproduce the problem, even with the same parameters.

[db48x]

The failures are all unrelated to this particular patch.

[katemonster33]

So I rebased this branch against master and compared it to current master. The wrapping works now on the spell list but what happened to the keybinding instructions on the spell list?
before:
after:

[db48x]

Nice. They’re supposed to still be there, but beneath the spell info. It worked before; perhaps I broke it when I rebased it last.

[db48x]

I’ve tried again to make the spell info take up the full available width of the column, but I think I am ready to give up on that. Again.

[katemonster33]

Hmmmmm. Let me have a look.

[katemonster33]

Whoops, I was trying to suggest that change, not commit it outright. Feel free to revert it if I broke stuff.

[db48x]

Yea, I guess we might as well do that.

clang++: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [Makefile:1046: cataclysm-tiles] Error 1

I got this with a non-clean make after recent builds of newer master branch, and the same results with make clean && make. My make parameters are RELEASE=0 LTO=0 TILES=1 SOUND=1 LOCALIZE=0 CLANG=1 CCACHE=1 BACKTRACE=0 ASTYLE=0 LINTJSON=0 TESTS=0 RUNTESTS=0 HEADERPOPULARITY=1

I'm also having this problem on master now this is merged with make -j$((`nproc`+0)) CCACHE=1 RELEASE=1 MSYS2=1 DYNAMIC_LINKING=1 SDL=1 TILES=1 SOUND=1 LOCALIZE=0 LANGUAGES=all LINTJSON=0 ASTYLE=0 TESTS=0 RUNTESTS=0 HEADERPOPULARITY=1, removing HEADERPOPULARITY=1 makes it compile again

[db48x]

If using HEADERPOPULARITY=1 makes it fail to build, then you should file a bug about that. I notice that imgui.o is included twice in that build. Not sure why that would be, but it explains the error message.
