.SH "NAME"
appstreamcli \- Handle AppStream metadata and the AppStream index
.SH "SYNOPSIS"
.HP \w'\fBappstreamcli\fR\ 'u
\fBappstreamcli\fR [\fBCOMMAND\fR]
.SH "DESCRIPTION"
.PP
This manual page documents briefly the
\fBappstreamcli\fR
command\&.
.PP
\fBappstreamcli\fR
is a small helper tool to work with AppStream metadata and access the AppStream component index from the command\-line\&. The AppStream component index contains a list of all available software components for your distribution, matched to their package names\&. It is generated using AppStream XML or Debian DEP\-11 data, which is provided by your distributor\&.
.PP
For more information about the AppStream project and the other components which are part of it, take a look at the AppStream pages at
\m[blue]\fBFreedesktop\&.org\fR\m[]\&\s-2\u[1]\d\s+2\&.
.SH "OPTIONS"
.PP
\fBstatus\fR
.RS 4
Display various information about the installed metadata and the metadata cache\&.
.RE
.PP
\fBget \fR\fB\fIID\fR\fR
.RS 4
Get a component by it\*(Aqs identifier\&.
.RE
.PP
\fBs\fR, \fBsearch \fR\fB\fITERM\fR\fR
.RS 4
Search the AppStream component database for a given search term\&.
.RE
.PP
\fBwhat\-provides \fR\fB\fITYPE\fR\fR\fB \fR\fB\fITERM\fR\fR
.RS 4
Return components which provide a given item\&. An item type can be specified using the
\fB\fITYPE\fR\fR
parameter, a value to search for has to be supplied using the
\fB\fITERM\fR\fR
parameter\&.
.sp
Examples:
.sp
Get components which handle the "text/xml" mimetype\&.
.sp
\fBappstreamcli\fR
what\-provides mimetype "text/xml"
.sp
Get component which provides the "libfoo\&.so\&.2" library\&.
.sp
\fBappstreamcli\fR
what\-provides lib libfoo\&.so\&.2
.RE
.PP
\fBrefresh\fR, \fBrefresh\-cache\fR
.RS 4
Trigger a database refresh, if necessary\&. In case you want to force the database to be rebuilt, supply the
\fB\-\-force\fR
flag\&.
.sp
This command must be executed with root permission\&.
.RE
.PP
\fBdump \fR\fB\fIID\fR\fR
.RS 4
Dump the XML description of a component with the given ID\&.
.RE
.PP
\fBvalidate \fR\fB\fIFILES\fR\fR
.RS 4
Validate AppStream XML metadata for compliance with the specification\&.
.sp
Both XML metadata types, upstream and distro XML, are handled\&. The filetype which should be validated is determined automatically\&.
.sp
The
\fB\-\-pedantic\fR
flag triggers a more pedantic validation of the file, including minor and style issues in the report\&.
.RE
.PP
\fBvalidate\-tree \fR\fB\fIDIRECTORY\fR\fR
.RS 4
Validate AppStream XML metadata found in a file\-tree\&.
.sp
This performs a standard validation of all found metadata, but also checks for additional errors, like the presence of \&.desktop files and validity of other additional metadata\&.
.RE
.PP
\fBinstall \fR\fB\fIID\fR\fR
.RS 4
Install a software component by its ID\&.
.sp
This resolves the AppStream component ID to the package name which provides it and then calls the distribution\*(Aqs package manager to install the software\&.
.sp
This feature is experimental\&.
.RE
.PP
\fBput \fR\fB\fIFILE\fR\fR
.RS 4
Install a metadata file into the right directory on the current machine\&.
.RE
.PP
\fBcompare\-versions \fR\fB\fIVER1\fR\fR\fB \fR\fB\fI[CMP]\fR\fR\fB \fR\fB\fIVER2\fR\fR
.RS 4
Compare two version numbers\&. If two version numbers are given as parameters, the versions will be compared and the comparison result will be printed to stdout\&.
.sp
If a version number, a comparison operator and another version number are passed in as parameter, the result of the comparison operation will be printed to stdout, and
\fBappstreamcli\fR
will exit with a non\-zero exit status in case the comparison failed\&. The comparison operator can be one of the following:

\fBnew\-template \fR\fB\fITYPE\fR\fR\fB \fR\fB\fIFILE\fR\fR
.RS 4
Create a metainfo file template to be used by software projects\&. The
\fB\-\-from\-desktop\fR
option can be used to use a \&.desktop file as template for generating the example file\&.
.sp
The generated files contain example entries which need to be filed in with the actual desired values by the project author\&.
.sp
The first
\fITYPE\fR
parameter is the name of an AppStream component type\&. For a complete list check out
\m[blue]\fBthe documentation\fR\m[]\&\s-2\u[2]\d\s+2
or the help output of
\fBappstreamcli\fR
for this subcommand\&.
.RE
.PP
\fB\-\-details\fR
.RS 4
Print out more information about a found component\&.
.RE
.PP
\fB\-\-no\-color\fR
.RS 4
Don\*(Aqt print colored output\&.
.RE
.PP
\fB\-\-no\-net\fR
.RS 4
Do not access the network when validating metadata\&.
.sp
The same effect can be achieved by setting the
\fBAS_VALIDATE_NONET\fR
environment variable before running
\fBappstreamcli\fR\&.
