The spec grammar for `text-decoration-line` is:
`none | [ underline || overline || line-through || blink ]`
Which means that it's either `none`, or any combination of the other
values. This patch makes that parse for `text-decoration-line` and
`text-decoration`, stores the results as a Vector, and adjusts
`paint_text_decoration()` to run as a loop over all the values that are
provided.
As noted, storing a Vector of values is a bit wasteful, as they could be
stored as flags in a single `u8`. But I was getting too confused trying
to do that in a nice way.
This fixes issues with carriage return sequences.
Before, using <CR><NUL> as the return sequence wouldn't work at all,
and when using <CR><LF> there was an extra newline after every newline.
After this patch, the behaviour should be closer to the Telnet RFC.
By the time that property() gets called, we've already given every
single property a value, so we can just return it. This simplifies a
lot of places that were manually handling a lack of value
unnecessarily.
This function was written as if it returned `Optional<CSS::BoxSizing>`
but actually returned a plain `CSS::BoxSizing`, meaning if the property
was not set or was invalid, it would return whichever enum value was
first. This wasn't visible because we don't yet pay any attention to
the `box-sizing` property.
Alias values are represented by "alias-name=real-name".
We have a lot of repetitive code for converting between ValueID and
property-specific enums. Let's see if we can generate it. :^)
This first step just produces the enums, from a JSON file. The values in
there are a duplication of what's in Properties.json, but eventually
those will go away.
Both calls essentially only differ in one boolean, which dictates
whether to print the value in uppercase or lowercase.
Move the long function call into a new function and pass in the
"uppercase" boolean seperately to avoid having to write everything
twice.
Those functions only differ by the input type of `number`. No other
wrapper does this, as they rely on adjusting the type of the argument on
the caller side instead.
Avoid specializing too much by just doing the same for signed numbers.
- Use a vector or references for the transition chain since null shapes
are not allowed in the chain.
- Use Vector::in_reverse() for iterating the chain backwards.
Since 8209c2b570 was added the requires
check for copy_characters_to_buffer matched StringViews as well, which
caused unexpected null bytes to be inserted for non null-terminated
fields.
Previously only a QOI image decoder was available on the system. This
commit adds an encoder as well.
For now it only handles images with 4 channels (RGBA).
Disable cell editing when the ctrl key is pressed. This fixes a bug
where when doing ctrl+z (undo) and there are no more undo actions
on the undo_stack, then a "z" is entered into the cell.
Instead of having the undo operation only be able to undo one cell
for a given undo, make it able to handle multiple cells at a time.
