Description
.LP
This command shows information about the flake specified by the flake
reference \fIflake-url\fR. It resolves the flake reference using the
\fBflake registry\fR, fetches it, and prints some meta
data. This includes:
.IP "\(bu" 3
\f(CRResolved URL\fR: If \fIflake-url\fR is a flake identifier, then this is
the flake reference that specifies its actual location, looked up in
the flake registry.
.IP "\(bu" 3
\f(CRLocked URL\fR: A flake reference that contains a commit or content
hash and thus uniquely identifies a specific flake version.
.IP "\(bu" 3
\f(CRDescription\fR: A one-line description of the flake, taken from the
\f(CRdescription\fR field in \f(CRflake.nix\fR.
.IP "\(bu" 3
\f(CRPath\fR: The store path containing the source code of the flake.
.IP "\(bu" 3
\f(CRRevision\fR: The Git or Mercurial commit hash of the locked flake.
.IP "\(bu" 3
\f(CRRevisions\fR: The number of ancestors of the Git or Mercurial commit
of the locked flake. Note that this is not available for \f(CRgithub\fR
flakes.
.IP "\(bu" 3
\f(CRLast modified\fR: For Git or Mercurial flakes, this is the commit
time of the commit of the locked flake; for tarball flakes, it\(cqs the
most recent timestamp of any file inside the tarball.
.IP "\(bu" 3
\f(CRInputs\fR: The flake inputs with their corresponding lock file
entries.
.LP
With \f(CR--json\fR, the output is a JSON object with the following fields:
.IP "\(bu" 3
\f(CRoriginal\fR and \f(CRoriginalUrl\fR: The flake reference specified by the
user (\fIflake-url\fR) in attribute set and URL representation.
.IP "\(bu" 3
\f(CRresolved\fR and \f(CRresolvedUrl\fR: The resolved flake reference (see
above) in attribute set and URL representation.
.IP "\(bu" 3
\f(CRlocked\fR and \f(CRlockedUrl\fR: The locked flake reference (see above) in
attribute set and URL representation.
.IP "\(bu" 3
\f(CRdescription\fR: See \f(CRDescription\fR above.
.IP "\(bu" 3
\f(CRpath\fR: See \f(CRPath\fR above.
.IP "\(bu" 3
\f(CRrevision\fR: See \f(CRRevision\fR above.
.IP "\(bu" 3
\f(CRrevCount\fR: See \f(CRRevisions\fR above.
.IP "\(bu" 3
\f(CRlastModified\fR: See \f(CRLast modified\fR above.
.IP "\(bu" 3
\f(CRlocks\fR: The contents of \f(CRflake.lock\fR.
.SH
Options
.IP "\(bu" 3
\fB\f(CR--json\fR\fR
.IP
Produce output in JSON format, suitable for consumption by another program.
.LP
\fBCommon evaluation options:\fR
.IP "\(bu" 3
\fB\f(CR--arg\fR\fR \fIname\fR \fIexpr\fR
.IP
Pass the value \fIexpr\fR as the argument \fIname\fR to Nix functions.
.IP "\(bu" 3
\fB\f(CR--argstr\fR\fR \fIname\fR \fIstring\fR
.IP
Pass the string \fIstring\fR as the argument \fIname\fR to Nix functions.
.IP "\(bu" 3
\fB\f(CR--debugger\fR\fR
.IP
Start an interactive environment if evaluation fails.
.IP "\(bu" 3
\fB\f(CR--eval-store\fR\fR \fIstore-url\fR
.IP
The \fBURL of the Nix store\fR
to use for evaluation, i.e. to store derivations (\f(CR.drv\fR files) and inputs referenced by them.
.IP "\(bu" 3
\fB\f(CR--impure\fR\fR
.IP
Allow access to mutable paths and repositories.
.IP "\(bu" 3
\fB\f(CR--include\fR\fR / \f(CR-I\fR \fIpath\fR
.IP
Add \fIpath\fR to the Nix search path. The Nix search path is
initialized from the colon-separated \fB\f(CRNIX_PATH\fR\fR environment
variable, and is used to look up the location of Nix expressions using \fBpaths\fR enclosed in angle
brackets (i.e., \f(CR<nixpkgs>\fR).
.IP
For instance, passing
.LP
.EX
-I /home/eelco/Dev
-I /etc/nixos
.EE
.IP
will cause Nix to look for paths relative to \f(CR/home/eelco/Dev\fR and
\f(CR/etc/nixos\fR, in that order. This is equivalent to setting the
\f(CRNIX_PATH\fR environment variable to
.LP
.EX
/home/eelco/Dev:/etc/nixos
.EE
.IP
It is also possible to match paths against a prefix. For example,
passing
.LP
.EX
-I nixpkgs=/home/eelco/Dev/nixpkgs-branch
-I /etc/nixos
.EE
.IP
will cause Nix to search for \f(CR<nixpkgs/path>\fR in
\f(CR/home/eelco/Dev/nixpkgs-branch/path\fR and \f(CR/etc/nixos/nixpkgs/path\fR.
.IP
If a path in the Nix search path starts with \f(CRhttp://\fR or \f(CRhttps://\fR,
it is interpreted as the URL of a tarball that will be downloaded and
unpacked to a temporary location. The tarball must consist of a single
top-level directory. For example, passing
.LP
.EX
-I nixpkgs=https://github.com/NixOS/nixpkgs/archive/master.tar.gz
.EE
.IP
tells Nix to download and use the current contents of the \f(CRmaster\fR
branch in the \f(CRnixpkgs\fR repository.
.IP
The URLs of the tarballs from the official \f(CRnixos.org\fR channels
(see \fBthe manual page for \f(CRnix-channel\fR\fR) can be
abbreviated as \f(CRchannel:<channel-name>\fR. For instance, the
following two flags are equivalent:
.LP
.EX
-I nixpkgs=channel:nixos-21.05
-I nixpkgs=https://nixos.org/channels/nixos-21.05/nixexprs.tar.xz
.EE
.IP
You can also fetch source trees using \fBflake URLs\fR and add them to the
search path. For instance,
.LP
.EX
-I nixpkgs=flake:nixpkgs
.EE
.IP
specifies that the prefix \f(CRnixpkgs\fR shall refer to the source tree
downloaded from the \f(CRnixpkgs\fR entry in the flake registry. Similarly,
.LP
.EX
-I nixpkgs=flake:github:NixOS/nixpkgs/nixos-22.05
.EE
.IP
makes \f(CR<nixpkgs>\fR refer to a particular branch of the
\f(CRNixOS/nixpkgs\fR repository on GitHub.
.IP "\(bu" 3
\fB\f(CR--override-flake\fR\fR \fIoriginal-ref\fR \fIresolved-ref\fR
.IP
Override the flake registries, redirecting \fIoriginal-ref\fR to \fIresolved-ref\fR.
.LP
