cancer's Issues

Crash on window close

There's some some thread panicking or something when the runner loop is exited.

Add font ligature support

Supporting ligatures is not going to be easy considering how the rendering is currently done.

On the bright side Cairo and Pango easily support rendering text with ligatures, but they require the whole text to do the job (obviously).

As it currently stands the Renderer has a Cache with an LRU for glyph caching, what this does is using the value of the cell to store the font and compute the shape, which is then sent to Cairo for rendering, this means that each cell is rendered as a single grapheme.

To support ligatures instead of using PangoGlyphString it should use PangoGlyphItem, which is just a pair of PangoItem and PangoGlyphString, looking through the Pango documentation I haven't found a way to "slice" a PangoGlyphString, so I presume a PangoGlyphItem must be used for that.

To keep performance good, the cache should be computed based on neighboring cells, where a cell is a neighbor iff:

it's on the same row
it has the same style
is not an empty cell

This does completely break the nice property of the LRU cache just storing the grapheme, which meant it could be reused for other cells containing the same grapheme.

Regardless, I think this could be done with an option without making the code too ugly, so people who do not care about ligatures (me) can opt-out and gain some performance.

dumb question

where's the default config file? I see a -c flag.

Using transparent foreground/background leads to artifacts.

zsh completion is not completely rendered

Something's afoot.

Add option to disable bold fonts.

Support colored emojis

What kind of shitty terminal does not fully support emojis?

Reuse rows instead of dropping them.

As profiling shows in line insertion heavy programs dropping the rows has a high cost, consider some sort of object pool.

Broken scroll back reflow

Scroll back reflow seems to be slightly broken, here be regressions.

Scroll regions do not properly bound line feeds.

The end result is Linux menuconfig scrolling is broken, and since there's no redraw support it just stays broken.

Scrolling probably needs some refactoring to allow this, it's always been disgusting.

add screenshot to readme

why not?

Refactor platform handling

Platform stuff should be pickable at runtime and compile time with features.

The choice for window handling and surface creation and rendering and window handling should be separate, for example it should be able to have X11/GL as window/renderer, or X11/X11 for both, on macOS it should allow Cocoa/Quartz and Cocoa/GL.

Windows support

Add support for Windows.

This would imply a new thingy to handle the tty, I assume, and wrapping the Cairo Win32 bullshit, but that shouldn't be too hard.

I'm a little concerned about the current event driven design where the handling is actually in main, and the window is a separate thing in a different thread, I'm not sure how that works out, I might have to change that too, but shouldn't be too hard.

Add sixel support

I want this, everybody wants this, thanks.

Honestly I think this is gonna fuck everything up as far as the renderer is concerned, but alas.

'Self' does not have a constant size known at compile-time
