*color-scheme* clj/s

Color scheme currently in use during parsing.

=i clj/s

apply-props clj/s

(apply-props rf)

Stateful transducer, apply it over the output of token-stream to know which styling should be applied over each piece of text.

The results are pairs consisting of a property map and a string.

chunk->hiccup clj/s

(chunk->hiccup [{:keys [foreground background bold] :as props} text])

code->attrs clj/s

(code->attrs code)

Given a CSI code, return a map of properties it sets. A value of nil means the property gets unset.

color-24-bit clj/s

(color-24-bit [r g b])

color-8-bit clj/s

(color-8-bit code)

Parse a "8-bit" color, given the code that follows on ESC[38;5;<code>m.

color-schemes clj/s

Color schemes used in popular applications.

csi->attrs clj/s

(csi->attrs csi)

Given a CSI specifier, excluding ESC[ but including the final "m", convert it to a map of properties that it sets or unsets. Property values of nil indicate a reset/unset.

ESC clj/s

ASCII escape character (codepoint 27, hex 1b, octal 33).

get-color clj/s

(get-color n)

has-escape-char? clj/s

(has-escape-char? s)

Efficient check to see if a string contains an escape character.

hiccup-xform clj/s

Transducer that consumes strings of input, and produces hiccup elements. Useful when dealing with streaming input, since it will carry over the 'terminal state'.

next-csi clj/s

(next-csi s)

(next-csi s start)

parse-color clj/s

(parse-color fg-or-bg [colorspace & more])

Handle CSI code 38 and 48, used to specify 8 or 24 bit colors. This may consume up to 5 codes in total (ESC [38;2;r;g;bm). Returns the map of properties that get set, and the remaining, unconsumed codes.

parse-int clj/s

(parse-int s)

rgb->css clj/s

(rgb->css [_ r g b])

str-length clj/s

(str-length s)

Fast string length

str-scan clj/s

(str-scan pos s min max)

Starting at position pos, move forward as long as the characters at the current position are within the given range. Returns the new position.

str-split clj/s

(str-split s sep)

Like clojure.string/split, but uses a single character instead of a regex, allowing for faster operation.

text->hiccup clj/s

(text->hiccup text)

Convenience function for the basic case where you have a string of terminal output and want to turn it into hiccup. Returns a seq of [:span] elements.

token-stream clj/s

(token-stream string)

Tokenize a string, whereby each CSI sequence gets transformed into a map of properties. The result is a vector of strings and maps.

with-color-scheme clj/s macro

(with-color-scheme name & body)

Execute code with the given color scheme active, name must be one of :vga :cmd :osx :putty :mirc :xterm :ubuntu. For finer control bind to color-scheme directly.
