detect-text-language - Detect language of text using one of several available backends
This document describes version 0.001 of detect-text-language (from Perl distribution App-LinguaIdentifyAnyUtils), released on 2019-07-10.
% detect-text-language [options] <text>
Backends will be tried in order. When a backend is not available, or when it fails to detect the language, the next backend will be tried. Currently supported backends:
WebService::DetectLanguage (only when
try_remote_backendsis set to true)
* marks required options.
Can be specified multiple times.
API key for detectlanguage.com.
Only required if you use WebService::DetectLanguage backend.
- --config-path=filename, -c
Set path to configuration file.
- --config-profile=s, -P
Set configuration profile to use.
- --no-config, -C
Do not use any configuration file.
Choose output format, e.g. json, text.
Set output format to json.
When outputing as JSON, strip result envelope.
By default, when outputing as JSON, the full enveloped result is returned, e.g.:
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:
This script has shell tab completion capability with support for several shells.
To activate bash completion for this script, put:
complete -C detect-text-language detect-text-language
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 detect-text-language 'p/*/`detect-text-language`/'
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): ~/.config/detect-text-language.conf, ~/detect-text-language.conf, or /etc/detect-text-language.conf.
All found files will be read and merged.
To disable searching for configuration files, pass
You can put multiple profiles in a single file by using section names like
[SOMESECTION profile=SOMENAME]. Those sections will only be read if you specify the matching
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.
List of available configuration parameters:
backends (see --backends) dlcom_api_key (see --dlcom-api-key) format (see --format) naked_res (see --naked-res) text (see --text) try_remote_backends (see --try-remote-backends)
Specify additional command-line options.
