Colouring of prompts is now supported within the shell by prompt escapes. The prompt theme system has been updated. +Various changes have been added to make debugging of shell code easier: + - As noted in README, the option DEBUG_BEFORE_CMD is now set by default. + - In DEBUG traps, $ZSH_DEBUG_CMD gives the code for which the trap is + called as a string. + - "setopt ERR_EXIT" in a DEBUG trap causes the code not to be executed. + - $ZSH_SUBSHELL indicates the subshell level at which code is being + executed. + - The zsh/parameter module has various additional arrays similar to + the existing $funcstack and $functrace, namely $funcsourcetrace + and $funcfiletrace. The consistency and informativeness of + the output of all these arrays has been improved. + - Prompt escapes %x and %I show the source file and line number in + debug prompts (compare %N and %i which show names and line numbers + in the execution environment). + - The option NO_MULTI_FUNCDEF can turn off multiple definition of + functions at once, a rarely used feature that can cause problems + with misplaced "()". + - The "fc" builtin has been enhanced to make non-interactive use possible + and output consistent when the history is manipulated with "print -s". + The completion style accept-exact-dirs has been added. When true, this suppresses attempts to complete non-final directory segments of a filename path when the directory exists. (For example, /home/pws/src/zsh/ -- cgit 1.4.1
