Fabian Homborg	5c6c405b9e	Cache if tracing is enabled ... Like the comment said: That var lookup was kind of expensive. So we simply use variable dispatch like we do for countless other things.	2021-10-28 19:39:30 +02:00
ridiculousfish	a7f1d2c0c7	Add support for fish_trace variable to trace execution ... This adds support for `fish_trace`, a new variable intended to serve the same purpose as `set -x` as in bash. Setting this variable to anything non-empty causes execution to be traced. In the future we may give more specific meaning to the value of the variable. The user's prompt is not traced unless you run it explicitly. Events are also not traced because it is noisy; however autoloading is. Fixes #3427	2019-11-02 14:40:57 -07:00
