`regexp` feature uses the pcre2 library to enable the user to define
regular expressions for matching text and applying text formatting to
the matches. An example from the theme configuration I used to test
this:
[terminal.themes.win95.text_format_regexps]
"listing.subject" = { "\\[[^\\]]*\\]" = { attrs = "Bold" } }
"listing.from" = { "\\<[^\\>]*\\>(?:(?:\\s*$)|(?=,))" = { attrs = "Italics" } }
[terminal.themes.win95.text_format_regexps."pager.envelope.body"]
"^>.*$" = { attrs = "Italics" }
"\\d+\\s?(?:(?:[KkMmTtGg]?[Bb])|(?:[KkMmTtGg][Bb]?)(?=\\s))" = { attrs = "Bold | Underline" }
FormatTag describes a set of attributes, colors that exist in a
tag_table field of CellBuffer. The field of tag_associations contains
the hash of a tag and the {start,end} index of the cells that have this
attribute. A tag can thus be used many times.
An example of use is
let t = self.pager.insert_tag(FormatTag {
attrs: Attr::ITALICS,
..Default::default()
});
debug!("FormatTag hash = {}", t);
let (width, height) = self.pager.size();
for i in 0..height {
if self.pager.content[(0, i)].ch() == '>' {
self.pager.set_tag(t, (0, i), (width.saturating_sub(1), i));
}
}
This will set reply lines in text as italics.
This feature interface is not used anywhere yet.
Add attribute escape sequence support in terminal::ansi, which handles
converting strings with ansi escape sequences into meli's internal
terminal structures in order to incorporate them into the UI.
Text attributes have been rewritten as bit flags, so for example instead of
"BoldUnderline" you'd have to define "Bold | Underline" in your theme
settings.
Requested in #21
No logical reason for it not to be in the terminal module anymore (the
set_and_join* functions predate the terminal module which is why they
weren't there to begin with).
Merge ui crate with root crate.
In preparation for uploading `meli` as a separate crate on crates.io.
Workspace crates will need to be published as well and having a separate
`ui` crate and binary perhaps doesn't make sense anymore.
