Hokeylization-lite
Why can't I run my whole app or site through Google Translate and get a basic translation in another language?
Now, you can!
The name hokeylization
is a portmanteau, meaning 'hokey localization'
It's somewhat hokey because it's very simple: it sends strings to Google Translate
And it is simple, yet also very powerful. It has special support for HTML documents, HandlebarsJS templates, and Markdown files.
You can translate:
- a JavaScript object containing messages
- any number of files or directories, always traversing directories recursively
This is hokeylization-lite
In order to lighten the weight of this npm package, this branch does not include any localized translations of the hokeylization documentation
The tool works the same, you can translate any language to any language. However, the tool's documentation and command-line help output will only be in English
To see command-line help for the hokey
command in your native language, use the
regular hokeylization
package instead of hokeylization-lite
Read this in another language
This README.md document has been translated, using the hokeylization tool itself, into every language supported by Google Translate!
I'm certain it's not perfect, but I hope it's better than nothing!

Is there a problem with this translation of the README?
This particular translation of the original README may be flawed -- corrections are very welcome! Please send a pull request on GitHub, or if you're not comfortable doing that, open an issue
When you create a new GitHub issue about a translation, please do:
- include the page URL (copy/paste from browser address bar)
- include the exact text that is wrong (copy/paste from browser)
- please describe what is wrong -- is the translation incorrect? is the formatting broken somehow?
- kindly offer a suggestion of a better translation, or how the text should be properly formatted

Installation
To use the command line tool, install using npm
or yarn
:
npm install -g hokeylization
yarn global add hokeylization
To use as a library, install the lite
version, which is much smaller:
npm install -g hokeylization-lite
yarn global add hokeylization-lite
Then look at help for the hokey
command:
hokey --help
hokey -h
Want to see output in your langauge or another language?
hokey
tries to detect the language automatically from your shell's environment variables
You can force a language by setting the LC_ALL
environment variable:
LC_ALL=it hokey --help
Note that if you have installed hokeylization-lite
, command help is only available in English
Setup
Set the GOOGLE_TRANSLATE_PROJECT_ID
environment variable to identify your Google Translate project
Set the GOOGLE_APPLICATION_CREDENTIALS
environment variable to the JSON credentials you downloaded
after figuring out how authentication works on Google cloud (it can be fun)
If you're running from the source code, you can also put these in a .env
file in the source
directory they'll be loaded at runtime via dotenv
Translating a JavaScript string resource file
Your string table must be in a JavaScript file in one of these two forms:
ES6 export:
export default {
string_key: "some value",
another_key: "another value",
... more keys ...
}
CommonJS export
module.exports = {
string_key: "some value",
another_key: "another value",
... more keys ...
}
If this file was named myfile.en.js
, you can translate it to Spanish and German with:
hokey -l es,de -o myfile.LANG.js myfile.en.js
The LANG
in the above is special -- it is a reserved word in this tool!
The LANG
is replaced with the language code for the output files
Thus the above command creates the files:
myfile.es.js
myfile.de.js
The -l
/ --languages
option is a comma-separated list of ISO language codes
supported by Google Translate
If the output file already exists, it will be examined to determine which keys already exist. Existing keys will not be translated. Translations for missing keys will be generated and appended to the end of the JS object. The entire file is always rewritten.
To force retranslation all keys, use the -f
/ --force
option
Translating a directory of text files
You can also translate a directory of files. hokeylization will recursively visit every file in the directory and run its contents through Google Translate, and save the output to an identically named file in a separate directory tree
When the target of your translation is a directory, this mode is enabled
The -o
/ --outfile
option specifies the output directory
BIG WARNING: When translating directories, DO NOT specify an output directory that is within your input directory! If you do this, you will:
- induce infinite recursion
- run up your Google bill
- fill up your disk
- have less fun
Here is an example of what not to do:
hokey -l es -o templates/es templates # <--- DON'T DO THIS!
When this runs, translated files are written to templates/es
, and thus become new
source files to translate, since they are under templates/
-- this process continues
forever, don't do it!
Correct usage
OK, let's say you have some email templates in a directory:
templates/email/en/welcome.txt
templates/email/en/welcome.html
templates/email/en/verify-account.txt
templates/email/en/verify-account.html
templates/email/en/reset-password.txt
templates/email/en/reset-password.html
To translate all of these to Spanish and German, run:
hokey -l es,de -o templates/email/LANG templates/email/en
In the above, LANG
is a reserved word and will be replaced with the ISO language code
What happens when the above runs:
- The
templates/email/es
andtemplates/email/de
directories will be created (if they don't exist) - Every file in
templates/email/en
will be translated to Spanish and German- Existing output files will not be regenerated unless you use
-f
/--force
- Existing output files will not be regenerated unless you use
- You'll end up with an identical directory structure and files within
es
andde
like you have underen
Other options
Dry run
Pass -n
/ --dry-run
to display what would be done, but do not actually make any API calls or write any files
Force
Pass -f
/ --force
to always regenerate translations, even if they already exist
Match
Pass -m
/ --match
to limit the files processed when running in directory-mode
You may not always want to translate every file in your source directory to your target directory
The value of the -m
/ --match
option is a regex (beware shell quoting rules!) that specifies
which files should be translated
When in doubt, you can combine this option with -n
/ --dry-run
to see which files would be translated
Excludes
Sometimes your -m
matches too many files. Use the -e
/ --excludes
option to explicitly exclude
files that otherwise would have matched
You can list multiple regexes, separated by spaces
A common usage would be: --excludes node_modules dist \.git build tmp
Handlebars
The strings to translate might contain {{ handlebars }}
templates, either with two or three curly-braces
You probably DON'T want the stuff inside those templates to be translated
Pass the -H
/ --handlebars
flag, and anything within {{ ... }}
will not be translated
Markdown
Markdown is neither text nor html, so Google Translate has some difficulties with it
The -M
/ --markdown
flag enables special handling for markdown files
With markdown files, if you don't use the -M
flag, you will probably find these problems:
- Broken links. In the translation, a space character appears after a markdown link description ends (with
]
) but before its target link begins (with(
). This causes the markdown to render incorrectly, and the link is broken when viewing the document. - Code blocks get translated. Google translate doesn't know what markdown considers code and what it doesn't
- Incorrect spacing for indented code blocks. Spacing is difficult to preserve in translation
- Things inside of
backticks
will get translated, when you almost always want them to be literal values
When the -M
/ --markdown
flag is enabled:
- The pattern
] (
will be condensed to](
thus fixing the broken markdown links - A "no translate" wrapper will be placed around indented code blocks, preserving proper indentation and ensuring they are not translated
- A "no translate" wrapper will be placed around text within
backticks
to ensure that they are not translated
Process-as
Normally everything is processed as plain text
If your content is HTML, it will get mangled unless you pass the -p html
/ --process-as html
option
Filter
For the adventurous: when processing files in a directory, you can pass the -F
/ --filter
option
to filter the output before it is written to the filesystem
The value of this option must be a path to a JS file that exports a function named filter
The filter
function must be async
because await
will be called upon it
Before files are written to disk, the entire file contents will be passed to the filter
function as a string
The return value from the filter
function is what will actually be written to storage
Thus, you have total control over what will finally be written
The filter
script will be looked for in the following locations (with .js
will be appended to the filter
name, unless it already ends in .js
)
- The current directory
- A directory named
.hokey-filters
within the current directory - A directory named
${HOME}/.hokey-filters
, where${HOME}
is the current user's home directory - The built-in filters directory
Filter Parameters
The filter
string can be multiple words. In this case, the first word is the filter name, and
the remaining words will be passed as arguments to the filter
function
Help
Use -h
/ --help
to show help
JSON batch commands
With the -j
/ --json
option, you can run multiple coordinated hokey
commands
By convention this file is called hokey.json
, but you can name it whatever you want
If you pass a directory as the -j
option, hokey
will look for a hokey.json
in that directory
The JSON file should contain one object. Within that object, its property names are the same as
the command-line options, plus one additional property named hokey
The hokey
property is an array of commands to run. The properties declared within these commands will
override any duplicate declarations in the outer object.
Within each object in the hokey
array, you should specify a name
, and the input and output files
Here is an example of a hokey.json
{
"inputLanguage": "en",
"languages": "es,fr,ja", # can also be an array of strings
"force": false,
"match": null,
"processAs": null,
"excludes": ["exclude-1", "exclude-2"],
"handlebars": false,
"markdown": false,
"regular": false,
"dryRun": false,
"filter": "theFilter.js",
"hokey": [
{
"name": "locale names",
"infile": "messages/locales_en.js",
"outfile": "messages/locales_LANG.js",
"handlebars": true
},
{
"name": "CLI messages",
"infile": "messages/en_messages.js",
"outfile": "messages/LANG_messages.js",
"handlebars": true
},
{
"name": "README",
"infile": "README.md",
"outfile": "lang/LANG/",
"excludes": ["lang/", "node_modules/", "\\.git/", "tmp/"],
"filter": "relativizeMarkdownLinks lang",
"markdown": true,
"index": "lang/README.md"
}
]
}
Multiple input files
Pass an array of file paths as infiles
instead of a single path infile
, as in this example:
{
... [
{
"name": "my docs",
"infiles": ["README.md", "INSTALL.md", "TUTORIAL.md"],
"outfile": "docs/LANG/",
"markdown": true
]
}
Indexes
When translating to many languages, hokey
can create an index file that lists all the translations made
and provides links to them
When generating indexes, you can have only one input source
Pass the -I
/ --index
option, the value is where the index file will be generated, which can be a file
or a directory. If it's a directory, a default filename will be used, based on the template (see below)
Use the -A
/ --index-template
to determine how the index output is formatted. You can specify 'html',
'markdown', 'text', or the file path to your own HandlebarsJS template
If you specify your own template, you must also specify a file (not a directory) for the -I
/ --index
option
