Nixbot is an IRC bot supporting Nix-related functionality. It’s using a RabbitMQ broker maintained by @grahamc for sending messages via the {^_^} nick on freenode (and therefore can’t run on its own currently).
Nix can be evaluated by prefixing “> “:
<infinisil> > (import <nixpkgs> {}).hello.name
<{^_^}> "hello-2.10"
You can also define variables:
<infinisil> > pkgs = import <nixpkgs> {}
<{^_^}> pkgs defined
<infinisil> > pkgs.hello.name
<{^_^}> "hello-2.10"
The NixOS module makes sure that <nixpkgs> in NIX_PATH always points to the latest master nixpkgs version (updated once per minute).
You can define a key to string mapping via the ~,~ prefix:
<infinisil> ,ask = Feel free to ask any questions about NixOS!
<{^_^}> ask defined
<infinisil> ,ask
<{^_^}> Feel free to ask any questions about NixOS!
<infinisil> ,ask paul
<{^_^}> paul: Feel free to ask any questions about NixOS!
<paul> Ah, thanks!
<infinisil> ,ask =
<{^_^}> Undefined ask, was defined as: Feel free to ask any questions about NixOS!
<infinisil> ,
<{^_^}> Special commands: find locate tell - Commands sorted by use count, page 0 (use ,<n> to view page <n>): library tofu foo
The find command allows you to find files in nixpkgs with a specific suffix. The bot will link to the latest github master version
<infinisil> ,find setup.sh
<{^_^}> Found file: https://github.com/NixOS/nixpkgs/tree/014f1c9d/pkgs/stdenv/generic/setup.sh
<infinisil> ,find hello/default.nix
<{^_^}> Found file: https://github.com/NixOS/nixpkgs/tree/014f1c9d/pkgs/applications/misc/hello/default.nix
If there are multiple possible answers, it will choose the file with the most commits.
The locate command uses nix-index to find packages containing a certain file in their output. The bin subcommand only searches for binaries:
<infinisil> ,locate bin gcc
<{^_^}> Found in packages: gcc, gcj, gccgo, gfortran, gcc_debug, ccacheWrapper, gcc-unwrapped, distccWrapper, distccMasquerade
<infinisil> ,locate libass.so
<{^_^}> Found in packages: libass
tell allows you to record a message for a user that currently is not in the channel. It will get relayed to them when they type a message in the channel:
<infinisil> ,tell paul Remember to do the thing
<{^_^}> infinisil: I'll pass that on to paul
<paul> Hello!
<{^_^}> paul: 2 hours, 52 minutes ago <infinisil> Remember to do the thing
When you link to a GitHub pull request (or post its number), the bot will post some info about it.
