Implementation Details
|
|
----------------------
|
|
|
|
C variables starting with `rl_*` are declared by the readline library
|
|
(or are macros referring to variables from the libedit library).
|
|
See http://web.mit.edu/gnu/doc/html/rlman_2.html
|
|
|
|
This should only be used in the CLI SAPI.
|
|
Historically, the code lived in sapi/cli,
|
|
but many distributions build readline as a shared extension.
|
|
Therefore, that code was split into ext/readline so that this can dynamically
|
|
be loaded. With other SAPIs, readline is/should be disabled.
|
|
|
|
`readline_cli.c` implements most of the interactive shell(`php -a`).
