NAME

filter-org-by-headlines - Filter Org by headlines

VERSION

This document describes version 0.46 of filter-org-by-headlines (from Perl distribution App-OrgUtils), released on 2017-07-10.

SYNOPSIS

Usage:

 % filter-org-by-headlines [options] <input>

DESCRIPTION

This routine uses simple regex instead of Org::Parser, for faster performance.

OPTIONS

* marks required options.

Main options

--input=s*

Value is either a string or an array of strings.

Configuration options

--config-path=filename

Set path to configuration file.

Can be specified multiple times.

--config-profile=s

Set configuration profile to use.

--no-config

Do not use any configuration file.

Environment options

--no-env

Do not read environment for default options.

Filtering options

--ascendant-match=s

Only include headline whose ascendant matches this.

Value is either a string or a regex. If string is in the form of `/.../` or `/.../i` it is assumed to be a regex.

--has-tag=s@

Only include headline which have all these tags.

Can be specified multiple times.

--has-tags-json=s

Only include headline which have all these tags (JSON-encoded).

See --has-tag.

--is-done

Only include headline which is a done todo item.

--is-todo

Only include headline which is a todo item.

--lacks-tag=s@

Only include headline which lack all these tags.

Can be specified multiple times.

--lacks-tags-json=s

Only include headline which lack all these tags (JSON-encoded).

See --lacks-tag.

--level=i
--match=s

Only include headline which matches this.

Value is either a string or a regex. If string is in the form of `/.../` or `/.../i` it is assumed to be a regex.

--max-level=i
--min-level=i
--parent-match=s

Only include headline whose parent matches this.

Value is either a string or a regex. If string is in the form of `/.../` or `/.../i` it is assumed to be a regex.

Output options

--format=s

Choose output format, e.g. json, text.

Default value:

 undef
--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]

Result options

--return-array

Return array of strings instead of strings.

--without-content

Don't include headline content, just print the headlines.

--without-preamble

Don't include text before any headline.

Other options

--help, -h, -?

Display help message and exit.

--version, -v

Display program's version and exit.

COMPLETION

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

bash

To activate bash completion for this script, put:

 complete -C filter-org-by-headlines filter-org-by-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 filter-org-by-headlines 'p/*/`filter-org-by-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): ~/.config/filter-org-by-headlines.conf, ~/filter-org-by-headlines.conf, or /etc/filter-org-by-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.

Finally, you can 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.
