Loading olm.lua as weechat script with `/script load olm.lua' causes
errors like this:
```
/nix/store/43jbh7yxh8j4gjfzbvpd9clncah5dip1-weechat-matrix-bridge-2018-05-29/lib/ffi.so: undefined symbol: lua_tointeger
```
As `olm.lua' is loaded by `matrix.lua' it doesn't need to be included
manually by the weechat configuration.
In my previous PR I missed that ${sec.foobar} (syntax to retrieve
secrets in a weechat runtime) breaks the shell evaluation.
Furthermore `;` shall be used rather than `\n` to concat scripts and the
init config.
This aims to make the `weechat` package even more configurable. It
allows to specify scripts and commands using the `configure` function
inside a `weechat.override` expression.
The package can be configured like this:
```
with import <nixpkgs> { };
weechat.override {
plugins = { availablePlugins, ... }: {
plugins = builtins.attrValues availablePlugins;
init = ''
/set foo bar
/server add freenode chat.freenode.org
'';
scripts = [ "/path/to/script.py" ];
};
}
```
All commands are passed to `weechat --run-command "/set foo bar;/server ..."`.
The `plugins' attribute is not necessarily required anymore, if it's
sufficient to add `init' commands, the `plugins' will be
`builtins.attrValues availablePlugins' by default.
Additionally the result contains `weechat` and `weechat-headless`
(introduced in WeeChat 2.1) now.
Also add a wrapper generator that allows adding the plugins back
conveniently and corresponding documentation in the package notes
section of the nixpkgs manual.
They're still enabled by default, but now can be disabled.
Python has not been made optional due to the additional complexity of:
- python2 vs python3
- pync support on Darwin
Making Python support optional should be revisited at another time.
This reverts commit cd52c04456 and
others.
Managing certificates (including revoking certificates and adding
custom certificates) becomes extremely painful if every package in the
system potentially depends on a different copy of cacert. Also, it
makes updating cacert rather expensive.
make it easily possible to extend current buildInputs using override function.
eg.:
weechat.override { extraBuildInputs = [ pythonPackages.pync ]; }
i've removed pync since its plugin dependency which can now be added via
extraBuildInputs.
