Function: shell-dynamic-complete-environment-variable

shell-dynamic-complete-environment-variable is an interactive and byte-compiled function defined in shell.el.gz.

Signature

(shell-dynamic-complete-environment-variable)

Documentation

Dynamically complete the environment variable at point.

Completes if after a variable, i.e., if it starts with a "$".

This function is similar to comint-dynamic-complete-filename, except that it searches process-environment for completion candidates. Note that this may not be the same as the interpreter's idea of variable names. The main problem with this type of completion is that process-environment is the environment which Emacs started with. Emacs does not track changes to the environment made by the interpreter. Perhaps it would be more accurate if this function was called shell-dynamic-complete-process-environment-variable.

Returns non-nil if successful.
