Hello, I currently use following syntax of a task (the task is: file to source): ... atinit"code to be run before running task" \ atload"code to be run after running task" \ load"condition to load task, e.g. [[ $PROMPT = yes ]]" \ unload"condition to unload task, e.g. [[ $PROMPT = no ]]" wait"time to wait before loading task, # of seconds, alternative to 'load'" Background & motivation is: 1-code-line with substitution is sufficient to detect task that needs to be run. The substitution uses code execution, calls math function. It's task-management, elastic scheduler, in few lines of code, fast. So I wonder: has anyone seen in e.g. daily job, in some other technology, a syntax to specify complex things, tasks, that could be used? Or has some idea? Zsh can serialize hashes, so ZSH_TASKS array (on which the 1-code-line substitution operates) can hold very rich task specification. -- Best regards, Sebastian Gniazdowski
