ANTLR, ANother Tool for Language Recognition, is a language tool that provides a framework for constructing recognizers, interpreters, compilers, and translators from grammatical descriptions containing actions in a variety of target languages.
ApproachâThe route or walk in to the base of a climb. AscenderâAny mechanical device that slides upward when put on a fixed rope but catches when weight is put on it, allowing a climber to use the rope to move upward or to haul gear. Used in aid climbing, mountaineering rescue and caving.
Bouncing - v. Sport climbing technique used to regain the rock after falling and the climber is hanging free and out of reach of the rock. The climber climbs the rope hand over hand (very strenuous), and then drops. At the instant the climber lets go, the belayer hauls in slack thereby raising the climber.
