Dennis¶

Dennis is a set of utilities for working with PO files to ease development and improve quality. Translate POT files to find problems with localization in your code. Lint PO files for common problems like variable formatting, mismatched HTML, missing variables, etc.

It includes the following subcommands:

lint: Lints PO and POT files for problems including errors that can cause your production system to crash and problems in strings that can lead to poor translations.

The system allows for defining other variable formats.
status: Get a high-level status of a PO file including a list of unstranslated strings.
translate: Translates strings in PO files into something else! Comes with an HTML extractor (tokenizes strings so that only the text is translated) and a bunch of translations like Pirate!.

This is helpful for l10n testing, development, finding unicode/layout problems, amazing your friends, hilarious April 1st shenanigans, etc.

Specify the tokenizer/transform pipeline you want to use that combines things. Zombie? Sure! Shouty Zombie? Ok! Manic shouty Dubstep? Bring it on!

This also works on strings passed in as command line arguments and as stdin—it doesn’t have to be a PO file or in a PO format format. For example, Dennis uses Dennis to translate all Dennis commit messages into Pirate!. That’s how cool Dennis is!

Quick start¶

Install:

$ pip install dennis

Lint a PO file for problems:

$ dennis-cmd lint locale/fr/LC_MESSAGES/messages.po

Lint all your PO files for errors:

$ dennis-cmd lint --errorsonly locale/

Lint a POT file for problems:

$ dennis-cmd lint locale/templates/LC_MESSAGES/messages.pot

Translate a PO file in place into Pirate!:

$ dennis-cmd translate --pipeline=html,pirate \
    locale/xx/LC_MESSAGES/messages.po

Get help:

$ dennis-cmd

Translating!¶

Help¶

$ dennis-cmd translate --help

This lists available transforms, variable formats and other options.

Summary¶

Dennis can translate the strings in your PO file. For example, this does the default which extracts text from HTML strings and translates that text into Pirate:

$ dennis-cmd translate messages.po

Note

This translates the messages.po file in-place. If you don’t want that, then copy the file and translate the copy.

You can also translate strings on the command line:

$ dennis-cmd translate -s "Dennis is my friend"

You can translate stuff from stdin:

$ echo "Dennis can see the future" | dennis-cmd translate -

You can change the pipeline to use one of many exciting transforms. For example, this is extra-piraty and shouty!:

$ dennis-cmd translate --pipeline=pirate,pirate,shouty \
    -s "Dennis can make hard boiled eggs boil faster"

Dennis can translate around variable tokens in strings. By default, it translates around Python variable forms. You can specify other variable formats to translate around:

$ denis-cmd translate --varformat=python-format,python-brace-format

Note

The infrastructure is there for handling other variable formats, but only Python formats have been coded. Help me add additional formats that are used in your gettext strings!

For help and a list of variable formats and transforms, do this:

$ dennis-cmd translate

For more about pipelines, see Pipelines.

For more about other transforms, see Transforms.

For more about extending Dennis to do dirty things, see API.

Transforms¶

Dennis currently supports the following transforms:

name	description
anglequote	Encloses string in unicode angle quotes.
double	Doubles all vowels in a string.
dubstep	Translates text into dubstep. It’s an experience.
empty	Returns empty strings.
haha	Adds haha! before sentences in a string.
pirate	Translates text into Pirate!
redacted	Redacts everything.
reverse	Reverses strings.
shouty	Translates into all caps.
xxx	Adds xxx before and after lines in a string.
zombie	Zombie.

Aditionally, there’s the html transform which extracts the bits to be translated, but doesn’t do any translation itself:

name	description
html	Tokenizes HTML bits so only text is translated.

anglequote¶

The anglequote transform adds unicode angle quotes to the beginning and end of strings. This helps to make sure your code handles unicode strings and also some layout issues like when strings are cut off or overlapping.

double¶

The double transform doubles all vowels in the string.

dubstep¶

The dubstep transform is an experience.

First, it builds over the course of the string, so longer strings have more dubstepperies than short strings.

Second, it adds dupsteppish punctuation to punctuation.

empty¶

The empty transform nixes the string.

OMG! Why?!

This is helpful for building .pot files from .po files. Also, it’s sort of interesting to see a ui with no text in it.

haha¶

Haha! Adds “Haha!” before sentences in a string. Haha! The exclamation point is a non-ASCII character, so this is both fun and tests unicode handling!

pirate¶

The Pirate! translation has the following properties:

it’s longer than the English equivalent (tests layout issues)
it’s different than the English equivalent (tests missing gettext calls)
every string ends up with a non-ascii character (tests unicode handling)
looks close enough to the English equivalent that you can quickly figure out what’s wrong (doesn’t test your reading comprehension)

redacted¶

Xxx xxxxxxxx xxxxxxxxx xxxxxxx xxxxxxxxxx.

reverse¶

.LTR rof lufpleh semitemos si hcihw sgnirts sesreveR

shouty¶

THE SHOUTY TRANSFORM MAKES THINGS IN ALL ASCII UPPERCASE. SHOUTY SHOUTY SHOUTY.

xxx¶

The xxx transform wraps all lines in strings with xxx.

zombie¶

ThHA zHRmbARHA HGMZanRZZRHRMZm HGNMMZnRZ HGHAZBHG ARnHGHR zHRmbARHA!

html¶

The html transform extracts strings from HTML to be translated. This includes any TEXT nodes as well as the text in alt and title attributes.

Pipelines¶

A pipeline consists of one or more transforms connected together. The output of one transform is the input of the next transform.

Each transform takes an iterable of Tokens and outputs an iterable of Tokens. In this way, you can build your pipeline however you like. For more on this and how to build your own transforms, see API.

Sample string: “Dennis can make your dreams come true.”

Example pipelines:

pirate

Translates into Pirate!

Sample string:
```
Dennis can make yerr dreams come true. ye scalleywag!
```
Note that this isn’t extracting HTML, so it just considers that whole thing a single string.
shouty,pirate

Capitalizes everything in the string (including the html) then runs that through pirate.

Sample string:
```
DENNIS CAN MAKE YOUR DREAMS COME TRUE. ye scalleywag!
```
Note that this isn’t extracting HTML, so it just considers that whole thing a single string.
html,pirate,pirate,pirate,shouty

Extracts text from HTML to be translated, runs it through pirate multiple times, then runs it through shouty which results in an extra Piraty shouty string

Sample string:
```
DENNIS CAN MAKE YARRRRR DREAMS COME TRUE PREPARE TO BE BOARD'D!
YE LANDLUBBARRS! MATEY!.
```
empty,anglequote

Woah—where’d the words go? It’s like a ghost-town of a ui.

Sample string:
```
«»
```

Linting!¶

Help¶

$ dennis-cmd lint --help

This will list the available lint rules and codes, the variable formats and any additional options available.

Summary¶

Dennis can lint your translated PO files for Python formatting token issues:

$ dennis-cmd lint messages.po

This runs multiple lint rules on all the strings in the PO file generating a list of errors and a list of warnings.

Dennis can also lint your POT files and point out issues that can result in poor translations. You can lint POT files like this:

$ dennis-cmd lint messages.pot

Skipping rules string-by-string¶

In the extracted comment, you can tell Dennis to ignore lint rules (or all lint rules).

Ignore everything:

#. dennis-ignore: *
msgid "German makes up 10% of our visitor base"
msgstr "A német a látogatóbázisunk 10%-át teszi ki"

Ignore specific rules (comma-separated):

#. dennis-ignore: E101,E102,E103
msgid "German makes up 10% of our visitor base"
msgstr "A német a látogatóbázisunk 10%-át teszi ki"

Ignore everything, but note the beginning of the line is ignored by Dennis so you can tell localizers to ignore the ignore thing:

#. localizers--ignore this comment. dennis-ignore: *
msgid "German makes up 10% of our visitor base"
msgstr "A német a látogatóbázisunk 10%-át teszi ki"

Warnings and Errors¶

What’s a warning?¶

Warnings indicate the translated string is either outdated or a poor translation, but the string is fine in the sense that it won’t kick up an error in production.

For example, say the original string has a variable, but the translated string doesn’t use that variable.

That’s not great and probably means the translated string needs to be updated, but it won’t throw an error in production.

What’s an error?¶

Errors indicate problems with the translated string that will cause an error to be thrown. These should get fixed pronto.

For example, when the translated string has a Python variable that’s not in the original string. When this string is interpolated, it will kick up a Python error. That causes the software to die, users to be unhappy, tires to go flat, people to work on weekends, mass hysteria, etc. No one likes that. I don’t like that. You probably don’t like that, either.

Table of Warnings and errors¶

PO files¶

Code	Description
E101	Malformed variable missing type Only checks python-format variables. Example (Python): Error: malformed variables: %(count) msgid: "%(count)s view" msgstr: "%(count) view" >>> "%(count) view" % {"count": 5} Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: unsupported format character 'v' (0x76) at index 9 >>>
E102	Malformed variable missing right curly-brace For example `{foo` with missing `}`. Only checks python-brace-format variables. Example (Python): Error: malformed variables: {foo bar baz msgid: "{foo} bar baz" msgstr: "{foo bar baz" >>> "{foo bar baz".format(foo="some thing") Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: unmatched '{' in format >>>
E103	Malformed variable missing left curly-brace For example `foo}` with missing `{`. Only checks python-brace-format variables. Example (Python): Error: malformed variables: foo} msgid: "{foo} bar baz" msgstr: "foo} bar baz" >>> "foo}".format(foo="some thing") Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: Single '}' encountered in format string >>>
E104	Bad format character For example `%a`. Only checks python-format variables. Example (Python): Error: bad format character: %a msgid: "%s foo" msgstr: "%a FOO" >>> "%a" % (1, 2, 3) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: unsupported format character 'a' (0x61) at index 1 >>>
E201	Invalid variables in translated string There are formatting variable tokens in the translated string that aren’t in the original string. Example: Error: mismatched: invalid variables: {helpurl} msgid: "You can find help at {url}" msgstr: "You can find help at {helpurl}" In this example, “helpurl” won’t be in the list of variables to interpolate and this will throw a KeyError. That’s equivalent to this: >>> "You can find help at {helpurl}".format(url="http://example.com") Traceback (most recent call last): File "<stdin>", line 1, in <module> KeyError: 'helpurl' >>>
W202	Missing variables in translated string There are formatting variable tokens in the original string that aren’t in the translated string. Example: Warning: missingvars: missing variables: {url} msgid: "You can find help at {url}" msgstr: "Get help!"
E202	Missing variables in translated string For python-format positional variables (e.g. `%s`), it’s an error when the variable is missing from the translated string. Example: Error: missingvars: missing variables: %s msgid: "foo %s" msgstr: "FOO"
W301	String is all whitespace The translated string is all whitespace. Example: Error: blank: translated string is solely whitespace msgid: "Foo" msgstr: " "
W302	Translated string is identical to source string Example: Error: unchanged: translated string is same as source string msgid: "Foo" msgstr: "Foo"
W303	HTML is mismatched between source and translated strings Example: Error: html: different html: "<b>" vs. "<i>" msgid: "<b>Foo</b>" msgstr: "<i>Feh</i>"
W304	HTML is invalid and can’t be parsed

POT files¶

Code

Description

W500

Hard to read variable name

There are a series of letters and numbers which are hard to distinguish from one another: o, O, 0, l, 1. It’s not uncommon for a hard-working translator to misread and use the wrong character.

Example:

Warning: hardtoread: hard to read variable name "l"
msgid: "Title: {l}"d help at {url}"
msgstr: ""

W501

One character variable name

Using a one character variable name doesn’t give enough context to the translator about what’s being put in that variable.

Example:

Warning: onechar: one character variable name: "{t}"
msgid: "{t} | {c}"
msgstr: ""

W502

Multiple unnamed variables

Having one unnamed variable is ok since it’s not order-dependent. However, having more than one unnamed variable means those variabes must occur in an order specified outside of the string. This creates problems with RTL languages and any other language that might need to change the order of the variables to create a translation that makes sense.

Example:

Warning: multiple variables with no name
msgid: "%s replies to %s"
msgstr: ""

Statusing!¶

Help¶

$ dennis-cmd status --help

Summary¶

Sometimes you just want to see the high-level status of a PO file and also maybe see the list of untranslated strings.

You can do that with Dennis:

$ dennis-cmd status messages.po

This will spit out riveting PO metadata and strings statistics like the total number of translated strings, untranslated strings, fuzzy strings and percentage translated.

Additionally, you can tell Dennis to show you all the untranslated strings:

$ dennis-cmd status --showuntranslated messages.po

Now you can verify that translation has been completed on a PO file without reading through the PO file.

API¶

Dennis is actually a library with a commandline interface frontend. You can use the library without using the command line at all.

This could be useful for linting strings on a translation system, etc.

This documentation needs to be written, but I’m going to wait until the core stabilizies.

Recipes¶

linting all your PO files
linting your POT file
translate PO file to find problems with localization
selective MO compiling
commit-msg git hook
convert your web page into Pirate for April fools day

linting all your PO files ¶

Sometimes it’s good to just get a look at all the PO files and make sure they’re ok:

$ dennis-cmd lint locale/

It’ll give you a summary at the end.

linting your POT file ¶

Linting your POT file can reduce the number of issues that translators will stumble over. It’s good to lint it before you push new strings to translate:

$ dennis-cmd lint locale/templates/LC_MESSAGES/messages.pot

translate PO file to find problems with localization ¶

Use the Dennis translator to find l10n issues in your application without having to bother your translators.

For example, this translates strings into Pirate for a web application written in Python:

#!/bin/bash

mkdir -p locale/xx/LC_MESSAGES
cp locale/templates/LC_MESSAGES/messages.pot \
    locale/xx/LC_MESSAGES/messages.po

dennis-cmd translate \
    --pipeline=html,pirate \
    --varsformat=python-format,python-brace-format \
    locale/xx/LC_MESSAGES/messages.po

Now view your application with the xx locale and behold it’s Piratey wonderfulness!

There are a variety of transforms which have different properties and suss out different kinds of localization problems.

selective MO compiling ¶

The Dennis linter returns an exit code of 1 if the file(s) it’s linting have errors. You can trivially use this to selectively compile PO files into MO files iff they are error free 1:

#!/bin/bash

for pofile in `find locale/ -name "*.po"`
do
    dir=`dirname "$pofile"`
    stem=`basename "$pofile" .po`

    dennis-cmd lint --errorsonly "$pofile"
    if [ $? -ne 0 ]
    then
        echo "ERRORZ!!! Not compiling $pofile!"

    else
        msgfmt -o "${dir}/${stem}.mo" "$pofile"
    fi
done

1: Dennis doesn’t lint the Plural-Forms headers, so it’s still possible for the resulting .mo file to have errors. You can check for errors in the headers by passing the --check-header flag to msgfmt.

commit-msg git hook ¶

You can automatically translate all future commit messages for your git project by creating a commit-msg hook like this:

#!/bin/bash

# Pipe the contents of the commit message file through dennis to
# a temp file, then copy it back.
(cat < $1 | dennis-cmd translate - > $1.tmp) && mv $1.tmp $1

# We always exit 0 even if the dennis-cmd fails. If the dennis-cmd
# fails, you get your original commit message. No one likes it when
# shenanigans break your stuff for realz.
exit 0;

convert your web page into Pirate for April fools day ¶

The Dennis translator can take content from stdin. Translate entire HTML pages:

#!/bin/bash

(cat < "$1" | dennis-cmd translate --pipeline=html,pirate -) > "pirate_$1"

Or show how you really feel about April fools day on the Internet:

#!/bin/bash

(cat < "$1" | dennis-cmd translate --pipeline=html,haha -) > "haha_$1"

Project guide¶

Hacking on Dennis¶

This covers setting up Dennis to hack on. If you’re interested in using Dennis, but not hacking on it, then this probably isn’t going to be interesting to you.

Install Dennis and dependencies for development¶

Clone the repository from https://github.com/mozilla/dennis/
Create a virtual environment
Install dev requirements: pip install -r requirements-dev.txt

This should get you up and running.

Helping out¶

The non-exhaustive list of things to do are in the issue tracker.

If you want to write some code or fix a bug or add some docs or in some way contribute to Dennis, please do so using the following process:

Tell me what you’re planning to do before you do it. Preferably in a comment in the issue tracker on a relevant issue. If not as a comment, then email me.

After I’ve been informed and given approval, continue!
Create a new branch for your changes.
Make your changes!
Update documentation or write new documentation for the changes you’ve made.
Update the tests or write new tests for the changes you’ve made.
Submit a patch.

To make it easier for me to maintain Dennis, all changes should either:
1. be submitted as a pull request in Github, or
2. emailed to me as an appropriately formatted patch
If you don’t know how to do either, then maybe you can find someone to help you out.

That’s it!

Anyone who contributes code, tests or docs (in other words, has a git commit with their name on it) get added to the CONTRIBUTORS file. Yay!

Tests¶

Tests are in tests/. We use pytest as the test runner.

To run the tests, do:

$ pytest

Please write tests for changes you make.

Documentation¶

Documentation is in docs/. We use Sphinx as the documentation generator.

To build the docs, do:

$ cd docs/
$ make html

Please make changes to the documentation as required by the changes you make.

Release howto¶

Check out master tip.
Check to make sure setup.py and requirements-dev.txt files have correct versions of requirements.
Update version number in dennis/__init__.py
1. Set __version__ to something like 0.4.
2. Set __releasedate__ to something like 20120731.
Update CHANGELOG. Usually, I do something like:
```
git log --oneline v0.4..HEAD
```
replacing v0.4 with the most recent tag. Then I copy and paste that, remove uninteresting lines and add a header.
Verify correctness.
1. Run the tests with tox.
2. Review the README.rst.
3. Build the docs and review them.
Tag the release:
```
git tag -a v0.4
```
Copy the last section of the CHANGELOG into the tag commit message.
Push everything:
```
git push --tags official master
```

Update PyPI:

rm -rf dist/*
python setup.py sdist bdist_wheel
twine upload dist/*

Announce the release.
