-Character attribute manipulation API |
- |
-This module provides a domain-specific language (using Python syntax) |
-for the creation of text with additional display attributes associated |
-with it. It is intended as an alternative to manually building up |
-strings containing ECMA 48 character attribute control codes. It |
-currently supports foreground and background colors (black, red, |
-green, yellow, blue, magenta, cyan, and white), intensity selection, |
-underlining, blinking and reverse video. Character set selection |
-support is planned. |
- |
-Character attributes are specified by using two Python operations: |
-attribute lookup and indexing. For example, the string \"Hello |
-world\" with red foreground and all other attributes set to their |
-defaults, assuming the name twisted.conch.insults.text.attributes has |
-been imported and bound to the name \"A\" (with the statement C{from |
-twisted.conch.insults.text import attributes as A}, for example) one |
-uses this expression:: |
- |
- | A.fg.red[\"Hello world\"] |
- |
-Other foreground colors are set by substituting their name for |
-\"red\". To set both a foreground and a background color, this |
-expression is used:: |
- |
- | A.fg.red[A.bg.green[\"Hello world\"]] |
- |
-Note that either A.bg.green can be nested within A.fg.red or vice |
-versa. Also note that multiple items can be nested within a single |
-index operation by separating them with commas:: |
- |
- | A.bg.green[A.fg.red[\"Hello\"], " ", A.fg.blue[\"world\"]] |
- |
-Other character attributes are set in a similar fashion. To specify a |
-blinking version of the previous expression:: |
- |
- | A.blink[A.bg.green[A.fg.red[\"Hello\"], " ", A.fg.blue[\"world\"]]] |
- |
-C{A.reverseVideo}, C{A.underline}, and C{A.bold} are also valid. |
- |
-A third operation is actually supported: unary negation. This turns |
-off an attribute when an enclosing expression would otherwise have |
-caused it to be on. For example:: |
- |
- | A.underline[A.fg.red[\"Hello\", -A.underline[\" world\"]]] |
