                  [pattern]

List existing recipes, revisions, or packages in the cache (by default) or the remotes.

positional arguments:
  pattern               A pattern in the form
                        'pkg/version#revision:package_id#revision', e.g:
                        "zlib/1.2.13:*" means all binaries for zlib/1.2.13. If
                        revision is not specified, it is assumed latest one.

options:
  -h, --help            show this help message and exit
  -v [V]                Level of detail of the output. Valid options from less
                        verbose to more verbose: -vquiet, -verror, -vwarning,
                        -vnotice, -vstatus, -v or -vverbose, -vv or -vdebug,
                        -vvv or -vtrace
  -cc CORE_CONF, --core-conf CORE_CONF
                        Define core configuration, overwriting global.conf
                        values. E.g.: -cc core:non_interactive=True
  -f FORMAT, --format FORMAT
                        Select the output format: json, html, compact
  -p PACKAGE_QUERY, --package-query PACKAGE_QUERY
                        List only the packages matching a specific query, e.g,
                        os=Windows AND (arch=x86 OR compiler=gcc)
  -fp FILTER_PROFILE, --filter-profile FILTER_PROFILE
                        Profiles to filter the binaries
  -fs FILTER_SETTINGS, --filter-settings FILTER_SETTINGS
                        Settings to filter the binaries
  -fo FILTER_OPTIONS, --filter-options FILTER_OPTIONS
                        Options to filter the binaries
  -r REMOTE, --remote REMOTE
                        Remote names. Accepts wildcards ('*' means all the
                        remotes available)
  -c, --cache           Search in the local cache
  -g GRAPH, --graph GRAPH
                        Graph json file
  -gb GRAPH_BINARIES, --graph-binaries GRAPH_BINARIES
                        Which binaries are listed
  -gr GRAPH_RECIPES, --graph-recipes GRAPH_RECIPES
                        Which recipes are listed
  --lru LRU             List recipes and binaries that have not been recently
                        used. Use a time limit like --lru=5d (days) or
                        --lru=4w (weeks), h (hours), m(minutes)

The conan list command can list recipes and packages from the local cache, from the specified remotes or from both. This command uses a reference pattern as input. The structure of this pattern is based on a complete Conan reference that looks like:

name/version@user/channel#rrev:pkgid#prev

This pattern supports using * as wildcard as well as #latest to specify the latest revision (though that might not be necessary in most cases, by default Conan will be listing the latest revisions).

Using it you can list:

  • Recipe references (name/version@user/channel).

  • Recipe revisions (name/version@user/channel#rrev).

  • Package IDs and their configurations (name/version@user/channel#rrev:pkgids).

  • Package revisions (name/version@user/channel#rrev:pkgids#prev).

Warning

The json output of the conan list --format=json is in preview. See the Conan stability section for more information.

Let’s see some examples on how to use this pattern:

Listing recipe references

list all references on local cache
  # Make sure to quote the argument
  $ conan list
  Local Cache
    hello
      hello/2.26.1@mycompany/testing
      hello/2.20.2@mycompany/testing
      hello/1.0.4@mycompany/testing
      hello/2.3.2@mycompany/stable
      hello/1.0.4@mycompany/stable
    string-view-lite
      string-view-lite/1.6.0
    zlib
      zlib/1.2.11

This command is equivalent to ``$ conan list "*"`` (make sure to quote the argument), if no argument
is provided Conan will list all packages.
list all versions of a reference
  $ conan list zlib
  Local Cache
    zlib
      zlib/1.2.11
      zlib/1.2.12

As we commented, you can also use the * wildcard inside the reference you want to search.

list all versions of a reference, equivalent to the previous one
# Make sure to quote the argument
$ conan list "zlib/*"
Local Cache
  zlib
    zlib/1.2.11
    zlib/1.2.12

You can also use version ranges in the version field to define the versions you want:

list version ranges
# Make sure to quote the argument
$ conan list "zlib/[<1.2.12]" -r=conancenter
Local Cache
  zlib
    zlib/1.2.11
$ conan list "zlib/[>1.2.11]" -r=conancenter
Local Cache
  zlib
    zlib/1.2.12
    zlib/1.2.13

Use the pattern for searching only references matching a specific channel:

list references with ‘stable’ channel
$ conan list "*/*@*/stable"
Local Cache
  hello
    hello/2.3.2@mycompany/stable
    hello/1.0.4@mycompany/stable

Use the ...@ pattern for searching only references that don’t have user and channel:

list references without user and channel
$ conan list "*/*@"
Local Cache
  string-view-lite
    string-view-lite/1.6.0
  zlib
    zlib/1.2.11

Listing recipe revisions

The shortest way of listing the latest recipe revision for a recipe is using the name/version@user/channel as the pattern:

list latest recipe revision
$ conan list zlib/1.2.11
Local Cache
  zlib
    zlib/1.2.11
      revisions
        ffa77daf83a57094149707928bdce823 (2022-11-02 13:46:53 UTC)

This is equivalent to specify explicitly that you want to list the latest recipe revision using the #latest placeholder:

list latest recipe revision
$ conan list zlib/1.2.11#latest
Local Cache
  zlib
    zlib/1.2.11
      revisions
        ffa77daf83a57094149707928bdce823 (2022-11-02 13:46:53 UTC)

To list all recipe revisions use the * wildcard:

list all recipe revisions
  $ conan list "zlib/1.2.11#*""
  Local Cache
    zlib
      zlib/1.2.11
        revisions
          ffa77daf83a57094149707928bdce823 (2022-11-02 13:46:53 UTC)
          8b23adc7acd6f1d6e220338a78e3a19e (2022-10-19 09:19:10 UTC)
          ce3665ce19f82598aa0f7ac0b71ee966 (2022-10-14 11:42:21 UTC)
          31ee767cb2828e539c42913a471e821a (2022-10-12 05:49:39 UTC)
          d77ee68739fcbe5bf37b8a4690eea6ea (2022-08-05 17:17:30 UTC)

Listing package IDs

The shortest way of listing all the package IDs belonging to the latest recipe revision is using name/version@user/channel:* as the pattern:

list all package IDs for latest recipe revision
  # Make sure to quote the argument
  $ conan list "zlib/1.2.11:*"
  Local Cache
    zlib
      zlib/1.2.11
        revisions
          d77ee68739fcbe5bf37b8a4690eea6ea (2022-08-05 17:17:30 UTC)

                options
                  fPIC: True
                  shared: False

Note

Here the #latest for the recipe revision is implicit, i.e., that pattern is equivalent to zlib/1.2.11#latest:*

To list all the package IDs for all the recipe revisions use the * wildcard in the revision # part:

Listing package revisions

The shortest way of listing the latest package revision for a specific recipe revision and package ID is using the pattern name/version@user/channel#rrev:pkgid

Note

Here the #latest for the recipe revision is implicit, i.e., that pattern is equivalent to zlib/1.2.11#latest:*#*

Listing graph artifacts

When the conan list --graph=<graph.json> graph json file is provided, the command will list the binaries in it. By default, it will list all recipes and binaries included in the dependency graph. But the --graph-recipes=<recipe-mode> and --graph-binaries=<binary-mode> allow specifying what artifacts have to be listed in the final result, some examples:

  • conan list --graph=graph.json --graph-binaries=build list exclusively the recipes and binaries that have been built from sources

  • conan list --graph=graph.json --graph-recipes="*" list exclusively the recipes, all recipes, but no binaries

  • conan list --graph=graph.json --graph-binaries=download list exclusively the binaries that have been downloaded in the last conan create or conan install

Filtering packages

There are a few ways to filter the packages that are returned by the command:

  • The --package-query option allows to filter the packages that match a specific query, for example --package-query="os=Windows AND (arch=x86 OR compiler=gcc)" would match only Windows packages where the architecture is x86 or the compiler is gcc.

  • You can filter packages by profiles (--filter-profile), settings (--filter-settings), or options (--filter-options). Note that only declared settings and options in the recipe will be considered for filtering, so that if for example a recipe does not declare the shared option, its packages will always be returned when using the --filter-options="*:shared=True" filter (regardless of the shared value used)

Both ways can be used together, and only the packages that match both filters will be listed

List json output format

Note

Best practices

The text output in the terminal should never be parsed or relied on for automation, and it is intended for human reading only. For any automation, the recommended way is using the formatted output as json

The conan list ... --format=json will return a json output in stdout (which can be redirected to a file) with the following structure:

# Make sure to quote the argument
$ conan list "zlib/1.2.11:*#*" --format=json
{
  "Local Cache": {
    "zli/1.0.0": {
      "revisions": {
        "b58eeddfe2fd25ac3a105f72836b3360": {
          "timestamp": "2023-01-10 16:30:27 UTC",
          "packages": {
            "9a4eb3c8701508aa9458b1a73d0633783ecc2270": {

            }
          }
        }
      }
    }
  }
}

List html output format

The conan list ... --format=html will return a html output in stdout (which can be redirected to a file) with the following structure:

$ conan list "zlib/1.2.13#*:*#*" --format=html -c > list.html

Here is the rendered generated HTML.

../../_images/conan-list-html.png

List compact output format

For developers, it can be convenient to use the --format=compact output, because it allows to copy and paste full references into other commands (like for example conan cache path):

$ conan list "zlib/1.2.13:*" -r=conancenter --format=compact
conancenter
  zlib/1.2.13
    zlib/1.2.13#97d5730b529b4224045fe7090592d4c1%1692672717.68 (2023-08-22 02:51:57 UTC)

        settings: Macos, x86_64, Release, apple-clang, 13
        options(diff): fPIC=True, shared=False
      zlib/1.2.13#97d5730b529b4224045fe7090592d4c1:abe5e2b04ea92ce2ee91bc9834317dbe66628206
        settings: Linux, x86_64, Release, gcc, 11
        options(diff): shared=True
      zlib/1.2.13#97d5730b529b4224045fe7090592d4c1:ae9eaf478e918e6470fe64a4d8d4d9552b0b3606
        settings: Windows, x86_64, Release, msvc, dynamic, Release, 192
        options(diff): shared=True
    ...

The --format=compact will show the list of values for settings, and it will only show the differences (“diff”) for options, that is, it will compute the common denominator of options for all displayed packages, and will print only those values that deviate from that common denominator.
