kandi X-RAY | autoenv Summary
If a directory contains a .env file, it will automatically be executed when you cd into it. When enabled (set AUTOENV_ENABLE_LEAVE to a non-null string), if a directory contains a .env.leave file, it will automatically be executed when you leave it. This is great for... You can also nest envs within each other. How awesome is that!?. When executing, autoenv, will walk up the directories until the mount point and execute all .env files beginning at the top.

QUESTION
For no justifiable reason at all, I have a pretty substantial Perl script embedded within a Bash function that is being invoked within an autoenv .env
file.
It looks something like this:
...ANSWER
Answered 2020-Sep-11 at 11:32There is this useful tidbit in the perlrun
man page, under the section for -x
, which "tells Perl that the program is embedded in a larger chunk of unrelated text, such as in a mail message."
All references to line numbers by the program (warnings, errors, ...) will treat the
#!
line as the first line. Thus a warning on the 2nd line of the program, which is on the 100th line in the file will be reported as line 2, not as line 100. This can be overridden by using the#line
directive. (See Plain Old Comments (Not!) inperlsyn
)
Based on the bolded statement, adding #line NNN
(where NNN
is the actual line number of the parent script where that directive appears) achieves the desired effect:
