render: add font_baseline() - calculates the y-coordinate for the baseline 
The old baseline calculation was copy-pasted to a couple of places,
and also assumed that the font's height was equal to ascent+descent.

While this is typically true, it isn't necessarily so.

Now, we assume that height >= ascent+descent, and then position the
baseline in "center" (but adjusted for the descent).

README.md

foot

foot is a fast Wayland terminal emulator.

Requirements

Running

  • fontconfig
  • freetype
  • pixman
  • wayland (client and cursor libraries)
  • xkbcommon

Building

In addition to the dev variant of the packages above, you need:

  • meson
  • ninja
  • wayland protocols
  • ncurses
  • scdoc

Fonts

foot supports all fonts that can be loaded by freetype, including bitmap fonts and color emoji fonts.

Foot uses its own font fallback mechanism, rather than relying on fontconfig's fallback. This is because fontconfig is quite bad at selecting fallback fonts suitable for a terminal (i.e. monospaced fonts).

Instead, foot allows you to specify a font fallback list, where each font can be configured independently (for example, you can configure the size for each font individually).

If a glyph cannot be found in any of the user configured fallback fonts, then fontconfig's list is used.

Shortcuts

At the moment, all shortcuts are hard coded and cannot be changed. It is not possible to define new key bindings.

Keyboard

  • shift+page up/down - scroll up/down in history
  • ctrl+shift+c - copy selected text to the clipboard
  • ctrl+shift+v - paste from clipboard
  • ctrl+shift+r - start a scrollback search

While doing a scrollback search, the following shortcuts are available:

  • ctrl+r - search for next match
  • esc - cancel the search
  • ctrl+g - cancel the search (same as esc)
  • return - finish the search and put the current match to the primary selection

Mouse

  • left - single-click: drag to select; when released, the selected text is copied to the primary selection. Note that this feature is normally disabled whenever the client has enabled mouse tracking, but can be forced by holding shift.
  • left - double-click: selects the word (separated by spaces, period, comma, parenthesis etc) under the pointer. Hold ctrl to select everything under the pointer up to, and until, the next space characters.
  • left - triple-click: selects the entire row
  • middle - paste from primary selection
