* Split up source files into several static libraries: misc + vtlib
* Add a new executable, pgo, that links to vtlib
* pgo is kind of like a mock test:
- provides stub implementations of functions not present in vtlib
- sets up a dummy terminal instance
- calls vt_from_slave() with static (pre-generated) content
Instead of writing (and logging errors for) every parameter, one at a
time, send all fixed size data in a single struct, followed by all the
variable length data.
When disabled, foot no longers uses outputs’ DPI to scale the
font. Instead, it uses the outputs’ scaling factor.
That is, instead of appending “:dpi=123” to the fontconfig string,
modify the “:pixelsize” or “:size” attribute.
Closes#206
When checking if we should allow a single-width character double-width
glyph to overflow into the next cell, require the next cell to either
be empty, or contain a space.
Closes#203
All alt+return combos mapped to the same escape sequence as alt+return
itself.
With this patch, alt+<mod(s)>+return map to a standard ‘CSI 27;x;13~’
sequence.
With XKB, Shift+Tab maps to XKB_KEY_ISO_Left_Tab, not
XKB_Key_Tab. Previously, we had two different lookup tables for the
two.
The tab table was correctly populated, while the ISO-left tab
wasn’t. As a result, all Shift+Tab combos (except Shift+Tab itself)
was wrong, and resulted in the same escape sequence as Shift+Tab.
Fix by using the same table for both tab and ISO-left tab.
Closes#210
* New function: rgb_to_hsl()
* New function: hsl_to_rgb()
* Replace XTerm’s hls_to_rgb() with our own, hsl_to_rgb().
* Ensure hue/lum/sat values are within range before calling
hsl_to_rgb()
Note that sixels’ use the following primary hues:
* blue: 0°
* red: 120
* green: 240°
While “standard” HSL uses:
* red: 0°
* green: 120°
* blue: 240°
Thus, we need to adjust the sixel’s hue value before calling
hsl_to_rgb().
