rimetadb - Manage a Rinci metadata database
This document describes version 0.226 of rimetadb (from Perl distribution App-rimetadb), released on 2023-07-09.
Scan all local Perl modules in the MyCompany:: namespace, get all Rinci metadata and store them in the database (defaults to dbi:SQLite:dbname=$HOME/rimeta.db where $HOME is the user's home directory.
MyCompany::
dbi:SQLite:dbname=$HOME/rimeta.db
$HOME
% rimetadb update-from-modules MyCompany::
Ditto, except we specify custom database location (note that this is not recommended, you should put username/password in config file instead of command-line options):
% rimetadb update-from-modules MyCompany:: \ --dsn 'mysql:database=mycompany_rimeta' --user ... --password ...
Update a single package metadata:
% rimetadb update --package MyCompany::Job \ --metadata-json '{"v":1.1,"summary":"Manage jobs"}'
Update a single function metadata:
% rimetadb update --package MyCompany::Job --function restart_job \ --metadata-json '{"v":1.1,"summary":"Restart a job","args":{"id":{"summary":"Job ID","schema":"int*","req":1},"force":{"schema":"bool"}}}'
Delete a single package metadata:
% rimetadb delete --package MyCompany::Job
Delete a single function metadata:
% rimetadb delete --package MyCompany::Job --function restart_job
Show some statistics (will be expanded further later):
% rimetadb stats
List packages in the database:
% rimetadb packages % rimetadb packages -l % rimetadb packages MyCompany
List functions in the database:
% rimetadb functions % rimetadb functions -l % rimetadb functions MyCompany
List function arguments in the database:
% rimetadb arguments % rimetadb arguments -l
Get metadata of function/package:
% rimetadb meta Foo::Bar::func
This script (and backend Perl module, App::rimetadb) maintains a database that catalogs Rinci metadata. The metadata can be used for various purposes:
Statistics
Average number of functions in a package. Average number of arguments in a function. Most often used schema data types for arguments. And so on.
Allow access to Perl functions via HTTP
See Perinci::Access::HTTP::Server and Riap.
Documentation
You can add Rinci metadata from installed Perl modules, or manually by specifying JSON or data structure via CLI or Perl API.
Show statistics on function arguments from the database.
List function arguments in the database.
Delete a package or function metadata from the database.
Show some statistics on functions from the database.
List functions in the database.
Get package/function metadata from the database.
List packages in the database.
Show some statistics from the database.
Add/update a package or function metadata in the database.
This routine lets you add/update a package or function metadata in the database with the specified metadata.
Update Rinci metadata database from local Perl modules.
This routine scans Perl modules, load them, and update the database using Rinci metadata from each modules into the database.
For each package, function, or function argument metadata, you can put this attribute:
'x.app.rimetadb.exclude' => 1,
to exclude the entity from being imported into the database. When you exclude a package, all its contents (currently functions) are also excluded.
* marks required options.
*
Set path to configuration file.
Can actually be specified multiple times to instruct application to read from multiple configuration files (and merge them).
Set configuration profile to use.
A single configuration file can contain profiles, i.e. alternative sets of values that can be selected. For example:
[profile=dev] username=foo pass=beaver [profile=production] username=bar pass=honey
When you specify --config-profile=dev, username will be set to foo and password to beaver. When you specify --config-profile=production, username will be set to bar and password to honey.
--config-profile=dev
username
foo
password
beaver
--config-profile=production
bar
honey
Shortcut for --log-level=debug.
DBI connection DSN.
If not specified, will default to dbd:SQLite:$HOME/rimeta.db where $HOME is user's home directory.
dbd:SQLite:$HOME/rimeta.db
Note: has been tested with MySQL and SQLite only.
Choose output format, e.g. json, text.
Default value:
undef
Output can be displayed in multiple formats, and a suitable default format is chosen depending on the application and/or whether output destination is interactive terminal (i.e. whether output is piped). This option specifically chooses an output format.
Display help message and exit.
Set output format to json.
Set log level.
By default, these log levels are available (in order of increasing level of importance, from least important to most): trace, debug, info, warn/warning, error, fatal. By default, the level is usually set to warn, which means that log statements with level info and less important levels will not be shown. To increase verbosity, choose info, debug, or trace.
trace
debug
info
warn
warning
error
fatal
For more details on log level and logging, as well as how new logging levels can be defined or existing ones modified, see Log::ger.
When outputing as JSON, strip result envelope.
0
By default, when outputing as JSON, the full enveloped result is returned, e.g.:
[200,"OK",[1,2,3],{"func.extra"=>4}]
The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use --naked-res so you just get:
--naked-res
[1,2,3]
Do not use any configuration file.
If you specify --no-config, the application will not read any configuration file.
--no-config
Do not read environment for default options.
If you specify --no-env, the application wil not read any environment variable.
--no-env
Filter output through a pager.
This option will pipe the output to a specified pager program. If pager program is not specified, a suitable default e.g. less is chosen.
less
DBI connection password.
Shortcut for --log-level=error.
List available subcommands.
Shortcut for --log-level=trace.
DBI connection user.
Shortcut for --log-level=info.
Display program's version and exit.
View output using a viewer.
This option will first save the output to a temporary file, then open a viewer program to view the temporary file. If a viewer program is not chosen, a suitable default, e.g. the browser, is chosen.
(No description)
Select specific function only.
Select specific package only.
Can also be specified as the 1st command-line argument.
Select arguments with specific type only.
(Fully-qualified) function name or package name.
See --metadata.
--metadata
Perl package names or prefixes to exclude (JSON-encoded).
See --exclude.
--exclude
Perl package names or prefixes to exclude.
You can also use this attribute in your package metadata:
to exclude the package (as well as its contents: all functions) from being imported into the database.
Can be specified multiple times.
Force update database even though module hasn't changed since last update.
Include library path, like Perl's -I.
Note that some modules are already loaded before this option takes effect. To make sure you use the right library, you can use PERL5OPT or explicitly use perl and use its -I option.
PERL5OPT
perl
-I
Perl module or prefixes or package to add/update (JSON-encoded).
See --module-or-package.
--module-or-package
Can also be specified as the 1st command-line argument and onwards.
Perl module or prefixes or package to add/update.
For each entry, you can specify:
a Perl module name e.g. Foo::Bar. An attempt will be made to load that module.
Foo::Bar
a module prefix ending with :: e.g. Foo::Bar::. Module::List will be used to list all modules under Foo::Bar:: recursively and load all those modules.
::
Foo::Bar::
Module::List
a package name using +Foo::Bar syntax. An attempt to load module with that name will not be made. This can be used to add an already-loaded package e.g. by another module).
+Foo::Bar
a package prefix using +Foo::Bar:: or +Foo::Bar:: syntax. Subpackages will be listed recursively (using Package::Util::Lite's list_subpackages).
+Foo::Bar::
list_subpackages
Require a Perl module, a la Perl's -m (JSON-encoded).
See --require.
--require
Require a Perl module, a la Perl's -m.
Use a Perl module, a la Perl's -M (JSON-encoded).
See --use.
--use
Use a Perl module, a la Perl's -M.
This script has shell tab completion capability with support for several shells.
To activate bash completion for this script, put:
complete -C rimetadb rimetadb
in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.
To activate tcsh completion for this script, put:
complete rimetadb 'p/*/`rimetadb`/'
in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
It is also recommended to install shcompgen (see above).
For fish and zsh, install shcompgen as described above.
This script can read configuration files. Configuration files are in the format of IOD, which is basically INI with some extra features.
By default, these names are searched for configuration filenames (can be changed using --config-path): /home/u1/.config/rimetadb.conf, /home/u1/rimetadb.conf, or /etc/rimetadb.conf.
--config-path
All found files will be read and merged.
To disable searching for configuration files, pass --no-config.
To put configuration for a certain subcommand only, use a section name like [subcommand=NAME] or [SOMESECTION subcommand=NAME].
[subcommand=NAME]
[SOMESECTION subcommand=NAME]
You can put multiple profiles in a single file by using section names like [profile=SOMENAME] or [SOMESECTION profile=SOMENAME] or [subcommand=SUBCOMMAND_NAME profile=SOMENAME] or [SOMESECTION subcommand=SUBCOMMAND_NAME profile=SOMENAME]. Those sections will only be read if you specify the matching --config-profile SOMENAME.
[profile=SOMENAME]
[SOMESECTION profile=SOMENAME]
[subcommand=SUBCOMMAND_NAME profile=SOMENAME]
[SOMESECTION subcommand=SUBCOMMAND_NAME profile=SOMENAME]
--config-profile SOMENAME
You can also put configuration for multiple programs inside a single file, and use filter program=NAME in section names, e.g. [program=NAME ...] or [SOMESECTION program=NAME]. The section will then only be used when the reading program matches.
program=NAME
[program=NAME ...]
[SOMESECTION program=NAME]
You can also filter a section by environment variable using the filter env=CONDITION in section names. For example if you only want a section to be read if a certain environment variable is true: [env=SOMEVAR ...] or [SOMESECTION env=SOMEVAR ...]. If you only want a section to be read when the value of an environment variable equals some string: [env=HOSTNAME=blink ...] or [SOMESECTION env=HOSTNAME=blink ...]. If you only want a section to be read when the value of an environment variable does not equal some string: [env=HOSTNAME!=blink ...] or [SOMESECTION env=HOSTNAME!=blink ...]. If you only want a section to be read when the value of an environment variable includes some string: [env=HOSTNAME*=server ...] or [SOMESECTION env=HOSTNAME*=server ...]. If you only want a section to be read when the value of an environment variable does not include some string: [env=HOSTNAME!*=server ...] or [SOMESECTION env=HOSTNAME!*=server ...]. Note that currently due to simplistic parsing, there must not be any whitespace in the value being compared because it marks the beginning of a new section filter or section name.
env=CONDITION
[env=SOMEVAR ...]
[SOMESECTION env=SOMEVAR ...]
[env=HOSTNAME=blink ...]
[SOMESECTION env=HOSTNAME=blink ...]
[env=HOSTNAME!=blink ...]
[SOMESECTION env=HOSTNAME!=blink ...]
[env=HOSTNAME*=server ...]
[SOMESECTION env=HOSTNAME*=server ...]
[env=HOSTNAME!*=server ...]
[SOMESECTION env=HOSTNAME!*=server ...]
To load and configure plugins, you can use either the -plugins parameter (e.g. -plugins=DumpArgs or -plugins=DumpArgs@before_validate_args), or use the [plugin=NAME ...] sections, for example:
-plugins
-plugins=DumpArgs
-plugins=DumpArgs@before_validate_args
[plugin=NAME ...]
[plugin=DumpArgs] -event=before_validate_args -prio=99 [plugin=Foo] -event=after_validate_args arg1=val1 arg2=val2
which is equivalent to setting -plugins=-DumpArgs@before_validate_args@99,-Foo@after_validate_args,arg1,val1,arg2,val2.
-plugins=-DumpArgs@before_validate_args@99,-Foo@after_validate_args,arg1,val1,arg2,val2

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
