SUBCOMMANDS
add-release

check
Check for parsing errors in Changes file.
dump
Dump Changes as JSON structure.

OPTIONS
*
marks required options.
Common options
- --config-path=s, -c
-
Set path to configuration file.
- --config-profile=s, -P
-
Set configuration profile to use.
- --file=s, -f
-
If not specified, will look for file called Changes/CHANGELOG/etc in current directory.
- --format=s
-
Choose output format, e.g. json, text.
Default value:
undef
- --help, -h, -?
-
Display help message and exit.
- --json
-
Set output format to json.
- --naked-res
-
When outputing as JSON, strip result envelope.
Default value:
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:
[1,2,3]
- --no-config, -C
-
Do not use any configuration file.
- --no-env
-
Do not read environment for default options.
- --page-result
-
Filter output through a pager.
- --subcommands
-
List available subcommands.
- --version, -v
-
Display program's version and exit.
- --view-result
-
View output using a viewer.
Options for subcommand add-release
- --change=s@*
-
Can be specified multiple times.
- --changes-json=s
-
See
--change
. - --date=s*

COMPLETION
This script has shell tab completion capability with support for several shells.
bash
To activate bash completion for this script, put:
complete -C cpan-changes cpan-changes
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.
tcsh
To activate tcsh completion for this script, put:
complete cpan-changes 'p/*/`cpan-changes`/'
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).
other shells
For fish and zsh, install shcompgen as described above.
CONFIGURATION FILE
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
): ~/.config/cpan-changes.conf, ~/cpan-changes.conf, or /etc/cpan-changes.conf.
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]
.
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
.
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.
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 has value equals something: [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 something: [env=HOSTNAME!=blink ...]
or [SOMESECTION env=HOSTNAME!=blink ...]
. If you only want a section to be read when an environment variable contains something: [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.
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:
[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
.
