Fabian Schmitthenner ff8d0698c7 fix nix-repl after we don't have a global store variable anymore (cf nix@c10c61449f954702ae6d8092120321744acd82ff) 2016-02-28 22:44:08 +00:00
Scott Olson 38816759fc Ignore blank inputs. 
Previously, nix-repl would consider this an incomplete parse and wait for the
next line as if it was a multiline input.

Blank lines in the middle of a multiline input will continue to work.

Scott Olson 87e6649fc3 Fix handling of whitespace. 
Whitespace will no longer be removed from input lines, which fixes pasting
multiline strings containing end-of-line or beginning-of-line whitespace.

Fixes #4,
 2016-02-18 06:27:39 -06:00
Scott Olson 287dfee35e Expand the help message printed from --help. 
Fixes #10. I consider this a temporary measure, however, until nix-repl has a
manpage (see #14). Then it can just open its manpage on --help like the other
nix tools do.

Much of the text in this commit was copied from nix-build's manpage.

Scott Olson cfc874ee52 Open the store before constructing EvalState. 
EvalState requires the `store` global to be initialized before it is constructed
in some cases, e.g. when it needs to download a tarball for something in
NIX_PATH. Hence, this fixes #13.
 2016-02-16 18:40:47 -06:00
Scott Olson 82aca33899 Add :i command to install a package to the current profile. 
It works by running `nix-env -i <derivation path>`.

Fixes #15.

Susan Potter 57aeef0b6a Fix nix-repl does not support '--help' 
According to popular practice and convention `nix-repl` now supports `--help`
like a good POSIX citizen[1].

Eelco Dolstra 3c67df928f Add sugar for defining a variable 
‘x = <expr>’ is short for ‘:a { x = <expr>; }’.  Note that the
right-hand side refers to the original scope, so you get:

  nix-repl> x = 1
  nix-repl> x = x + 1
  nix-repl> x
  2

rather than an infinite recursion.

Eelco Dolstra 4b33c2dd4c Add help (:?) 2013-09-09 13:22:33 +02:00
Eelco Dolstra e133e91410 Support tab-completion on attribute sets 
Example:

$ nix-repl '<nixos>'

> config.services.xserver.desktop<TAB>

comletes to

> config.services.xserver.desktopManager

You also get suggestions if there are multiple matches:

> config.services.xserver.desktopManager.kde4
config.services.xserver.desktopManager.kde4.enable
config.services.xserver.desktopManager.kde4.phononBackends

Eelco Dolstra 7e3625f924 Improved value display 
By default, we don't recurse into attribute sets or lists when
printing a value.  However, the new :p command does recurse.
