DESCRIPTION

This is a simple application to list headlines in Org files, first created as a demo for Org::Parser.

OPTIONS

* marks required options.

Main options

--file=s@*

(No description)

Can also be specified as the 1st command-line argument and onwards.

Can be specified multiple times.

--files-json=s

See --file.

Can also be specified as the 1st command-line argument and onwards.

--time-zone=s

Will be passed to parser's options.

If not set, TZ environment variable will be picked as default.

--today-json=s

Assume today's date (JSON-encoded).

See --today.

--today=s

Assume today's date.

You can provide Unix timestamp or DateTime object. If you provide a DateTime object, remember to set the correct time zone.

Configuration options

--config-path=s, -c

Set path to configuration file.

Can actually be specified multiple times to instruct application to read from multiple configuration files (and merge them).

--config-profile=s, -P

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.

--no-config, -C

Do not use any configuration file.

If you specify --no-config, the application will not read any configuration file.

Environment options

--no-env

Do not read environment for default options.

If you specify --no-env, the application wil not read any environment variable.

Output options

--format=s

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.

--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]
--page-result

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.

--view-result

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.

Other options

--allow-duplicates

Whether to allow headline to be listed more than once.

This is only relevant when group_by_tags is on. Normally when a headline has several tags, it will only be listed under its first tag. But when this option is turned on, the headline will be listed under each of its tag (which mean a single headline will be listed several times).

--detail, -l

Show details instead of just titles.

--done

Only show todo items that are done.

--due-in=s

Only show todo items that are (nearing|passed) due.

If value is not set, then will use todo item's warning period (or, if todo item does not have due date or warning period in its due date, will use the default 14 days).

If value is set to something smaller than the warning period, the todo item will still be considered nearing due when the warning period is passed. For example, if today is 2011-06-30 and due_in is set to 7, then todo item with due date <2011-07-10 > won't pass the filter (it's still 10 days in the future, larger than 7) but <2011-07-10 Sun +1y -14d> will (warning period 14 days is already passed by that time).

--from-level=s

Only show headlines having this level as the minimum.

Default value:

1
--group-by-tags

Whether to group result by tags.

If set to true, instead of returning a list, this function will return a hash of lists, keyed by tag: {tag1: [hl1, hl2, ...], tag2: [...]}. Note that a headline that has several tags will only be listed under its first tag, unless when allow_duplicates is set to true, in which case the headline will be listed under each of its tag.

--has-tag=s@

Only show headlines that have the specified tags.

Can be specified multiple times.

--has-tags-json=s

Only show headlines that have the specified tags (JSON-encoded).

See --has-tag.

--help, -h, -?

Display help message and exit.

--lacks-tag=s@

Only show headlines that don't have the specified tags.

Can be specified multiple times.

--lacks-tags-json=s

Only show headlines that don't have the specified tags (JSON-encoded).

See --lacks-tag.

--maximum-priority=s

Only show todo items that have at most this priority.

Note that the default priority list is [A, B, C] (A being the highest) and it can be customized using the #+PRIORITIES setting.

--minimum-priority=s

Only show todo items that have at least this priority.

Note that the default priority list is [A, B, C] (A being the highest) and it can be customized using the #+PRIORITIES setting.

--priority=s

Only show todo items that have this priority.

--sort-json=s

Specify sorting (JSON-encoded).

See --sort.

--sort=s

Specify sorting.

Default value:

"due_date"

If string, must be one of 'due_date', '-due_date' (descending).

If code, sorting code will get [REC, DUE_DATE, HL] as the items to compare, where REC is the final record that will be returned as final result (can be a string or a hash, if 'detail' is enabled), DUE_DATE is the DateTime object (if any), and HL is the Org::Headline object.

--state=s

Only show todo items that have this state.

--to-level=s

Only show headlines having this level as the maximum.

--todo

Only show headlines that are todos.

--version, -v

Display program's version and exit.

--with-unknown-priority

Also show items with no/unknown priority.

Relevant only when used with minimum_priority and/or maximum_priority.

If this option is turned on, todo items that does not have any priority or have unknown priorities will still be included. Otherwise they will not be included.

COMPLETION

This script has shell tab completion capability with support for several shells.

bash

To activate bash completion for this script, put:

complete -C list-org-headlines list-org-headlines

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 list-org-headlines 'p/*/`list-org-headlines`/'

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): /home/u1/.config/list-org-headlines.conf, /home/u1/list-org-headlines.conf, or /etc/list-org-headlines.conf.

All found files will be read and merged.

To disable searching for configuration files, pass --no-config.

You can put multiple profiles in a single file by using section names like [profile=SOMENAME] or [SOMESECTION 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 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.

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.

CONTRIBUTING

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.
