reload-module usage

reload-module usage

[Ramakrishnan Muthukrishnan]

Hi,

How to use the `reload-module' function? For eg:

> (use-modules (tekuti boot))
...
[do some editing in tekuti/boot.scm]
...
[now back to the repl]
> (reload-module (tekuti boot))

This gives the following output:

> (reload-module (tekuti boot))
<stdin>:18:15: warning: possibly unbound variable `tekuti'
<unnamed port>:18:16: In procedure module-lookup:
<unnamed port>:18:16: Unbound variable: tekuti

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
>

Perhaps I am missing something. Can't we specify the module name as we
specified in the use-module?

thanks

`reload-module' is indeed a function which explains the error. How do
we specify a module name?

It is a function that takes a module as an argument.

  (reload-module (resolve-module (tekuti boot)))

would be how to use it. I'll add a REPL meta-command that takes a
name. Having the core procedure take a module instead of a name takes
away an error case -- what if it wasn't loaded before, do we load it for
the first time?

Doh, I meant

    (reload-module (resolve-module '(tekuti boot)))
                                   ^
                 quote. it's like the pinky finger. small but important
