Dennis v0.6 released! Line numbers, double vowels, better cli-fu, and better output!

What is it?

Dennis is a Python command line utility (and library) for working with localization. It includes:

  • a linter for finding problems in strings in .po files like invalid Python variable syntax which leads to exceptions
  • a template linter for finding problems in strings in .pot files that make translator's lives difficult
  • a statuser for seeing the high-level translation/error status of your .po files
  • a translator for strings in your .po files to make development easier

v0.6 released!

Since v0.5, I've done the following:

  • Rewrote the command line handling using click and added an exception handler.
  • Merged the lint and linttemplate commands. Why should you care which file you're linting when the linter can figure it out for you?
  • Added the whimsical double vowel transform.
  • Added line numbers in the lint output. This will make it possible to find those pesky problematic strings in your .po/.pot files.
  • Add a line reporter to the linter.

Getting pretty close to what I want for a 1.0, so I'm pretty excited about this version.

Denise update

I've updated Denise with the latest Dennis and moved it to a better url. Lint your .po/.pot files via web service using http://denise.paas.allizom.org/.

Dennis v0.5 released! New lint rules, new template linter, bunch of fixes, and now a service!

What is it?

Dennis is a Python command line utility (and library) for working with localization. It includes:

  • a linter for finding problems in strings in .po files like invalid Python variable syntax which leads to exceptions
  • a template linter for finding problems in strings in .pot files that make translator's lives difficult
  • a statuser for seeing the high-level translation/error status of your .po files
  • a translator for strings in your .po files to make development easier

v0.5 released!

Since the last release announcement, there have been a handful of new lint rules added:

  • W301: Translation consists of just white space
  • W302: The translation is the same as the original string
  • W303: There are descrepancies in the HTML between the original string and the translated string

Additionally, there's a new template linter for your .pot files which can catch things like:

  • W500: Strings with variable names like o, O, 0, l, 1 which can be hard to read and are often replaced with a similar looking letter by the translator.
  • W501: One-character variable names which don't give translators enough context about what's being translated.
  • W502: Multiple unnamed variables which can't be reordered because the order the variables are expanded is specified outside of the string.

Dennis in action

Want to see Dennis in action, but don't want to install Dennis? I threw it up as a service, though it's configured for SUMO: http://dennis-sumo.paas.allizom.org/

Note

I may change the URL and I might create a SUMO-agnostic version. If you're interested, let me know.

Fiddling with Kibana

I just kicked off a script that's going to take around 4 hours to complete mostly because the API it's running against doesn't want me doing more than 60 requests/minute. Given I've got like 13k requests to do, that takes a while.

I'm (ab)using Elasticsearch to store the data from my script so that I can analyze it more easily--terms facet is pretty handy here.

Given that I've got some free time now, I spent 5 minutes setting up Kibana.

Steps:

  1. download the tarball
  2. untar it into a directory
  3. edit kibana-3.0.1/config.js to point to my local Elasticsearch cluster (the defaults were fine, so I could have skipped this step)
  4. cd kibana-3.0.1/ and run python -m SimpleHTTPServer 5000 (I'm using a Python-y thing here, but you can use any web-server)
  5. point my browser to http://localhost:5000

Now I'm using Kibana.

Now that I've got it working, first thing I do is click on the cog in the upper right hand corner, click on the Index tab and change the index to the one I wanted to look at. Now I'm looking at the data my script is producing.

The Kibana site says Kibana excels at timestamped data, but I think it's helpful for what I'm looking at now despite it not being timestamped. I get immediate terms facets on the fields for the doc type I'm looking at. I can run queries, pick specific columns, reorder, do graphs, save my dashboard to look at later, etc.

If you're doing Elasticsearch stuff, it's worth looking at if only to give you another tool to look at data with.

Dennis v0.4 released! Tweaks to Python 3 support, overhauled linter, string-by-string lint rules ignoring

What is it?

Dennis is a Python command line utility (and library) for working with localization. It includes:

  • a linter for finding problems in strings in .po files like invalid Python variable syntax which leads to exceptions
  • a statuser for seeing the high-level translation/error status of your .po files
  • a translator for strings in your .po files to make development easier

v0.4 released!

v0.4 sports an overhauled linter. Instead of two rules ("malformed" and whatever the other one was), it now has a bunch of much smaller and more specific rules! Also, I renamed the rules so they are all numbered!

See the table of error/warning rules and their numbers here: http://dennis.readthedocs.org/en/v0.4/linting.html#warnings-and-errors

Additionally, dennis hits false positives for a variety of reasons. If you're doing a "keep the errors out of production!" kind of thing, then false positives can prevent locale files from making it. That sucks!

To alleviate this, dennis now allows you to tell it what to ignore in the extracted comments. What's an extracted comment? It's a comment in the .po file that starts with #.. You can specify the extracted comments with "context" or similar mechanisms depending on how you're extracting strings. You can tell dennis to skip specific rules or skip all the rules on a string-by-string basis.

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"

I also tweaked some of the Python 3 support code because it looked at me funny.

Also, universal wheel!

Dennis v0.3.11 released! Fixes and Python 3 support

What is it?

Dennis is a Python command line utility (and library) for working with localization. It includes:

  • a linter for finding problems in strings in .po files like invalid Python variable syntax which leads to exceptions
  • a statuser for seeing the high-level translation/error status of your .po files
  • a translator for strings in your .po files to make development easier

v0.3.11 released!

v0.3.11 adds Python 3 support (there might be problems, but it's working for me) and adds error detection for the case where there's a } but no {.

Definitely worth updating!

8 out of 11 people who have heard of Dennis and continue to ignore its baby mews of wonderfulness also have a severe allergy to rainbows and kittens.

pyvideo status: April 9th, 2014

What is pyvideo.org

pyvideo.org is an index of Python-related conference and user-group videos on the Internet. Saw a session you liked and want to share it? It's likely you can find it, watch it, and share it with pyvideo.org.

Status

I fixed a few issues and finally (finally) pushed out major site updates. Some of them are implemented in the worst possible way (e.g. facet filters for the search page), but some of them are great (e.g. Amara subtitle support).

I'm still struggling with a lot of technical debt on the site and a lack of time to really focus on it. That's mostly what's been making fixing the issues, improving the site and adding conferences take so long.

Sheila and I will be at PyCon US and hanging around for sprint days. If anyone is interested in sprinting, we'll be there. Even if we don't get any coding done, figuring out how to solve some of the bigger problems and planning what should be done in the next year would be a huge accomplishment.

If you're at PyCon and see either of us, feel free to give us a piece of your mind in regards to how you use PyVideo and what could be better.

Site development using pagekite

Problem

I have this basic problem where I do a lot of web-site work and I need to show people what I've done so far so they can review it and help me make it better or make it suit their needs better. Screenshots aren't very helpful because the site is interactive. Further, the site needs to get tested on multiple devices/platforms/browsers. Also, I need to make sure that the site is only accessed via https.

What I've been doing up to now is failing miserably: I'd push work to our staging server for people to test out, but that sucks as an answer and affects my co-workers and makes a mess of our staging server. Plus iterating on things is difficult.

So, requirements:

  1. endpoint must be https-only
  2. must be easy to set up and take down
  3. must be easy to access so people can easily test things on my local machine

Solution

I looked around and this would be pretty easy to do if I didn't have the https-only requirement. That makes things difficult without a lot of work.

Then I found pagekite. They make it really easy.

Here's how you set it up:

  1. Download and install the pagekite software: http://pagekite.net/downloads/

  2. Run your website. In my case, I'm working on Django sites, so I launch like this:

    $ ./manage.py runserver
    

    That runs the Django project I'm working on on localhost:8000.

  3. Run pagekite:

    $ pagekite.py 8000 YOUR_NAME.pagekite.me:443
    

    That creates a tunnel from your machine to the pagekite.me server. When someone accesses https://YOUR_NAME.pagekite.me/, the request goes through the tunnel to your pagekite backend and that performs the request over http to your local webserver (in my case, the Django project) bound to localhost:8000.

    Access is https-only. If anyone tries to access http://YOUR_NAME.pagekite.me/, then they get a connection error.

    The https-only requirement is satisfied by restricting the kite to only listening to port 443--the https port. That's pretty key.

This lets me run my Django project locally on http without dealing with self-signed certificates, but still require https access so data isn't floating around in clear text.

The one problem with this is that my local server thinks it's running http and so redirects that include the protocol go to http rather than https.

If you don't already have an account, I'm pretty sure step 3 will walk you through setting one up. Free accounts are limited in what they can do.

Also, they hang out on #pagekite on Freenode. I had a problem, asked a question and got a super helpful reply. The code is Open Source, so it's possible to look through it and debug it.

I'll be using this going forward.

Why write this?

This is a common use case for web developers. I figured I'd write this up because the https-only part is pretty key and it was the part that I had to ask for help with.

ElasticUtils v0.9 released!

What is it?

ElasticUtils is a Python library for building and executing Elasticsearch searches.

See the Quickstart for more details.

v0.9 released!

This is a big release, but there are some compromises in it that I'm not wildly excited about. Things like Elasticsearch 1.0 support didn't make the cut. I'm really sorry about that---we're working on it.

This release has a lot of changes in it. Roughly:

  • dropped pyelasticsearch for elasticsearch-py (Thank you Honza!)
  • fixed S.all() so it does what Django does which should let you use an S in the place of a QuerySet in some cases
  • new FacetResult class (Thank you James!)
  • S.facet() can take a size keyword
  • cleaned up ESTestCase
  • SearchResults now has facet data in the facets property
  • etc.

For the complete list of what's new, What's new in Version 0.9.

Many thanks to everyone who helped out: Alexey Kotlyarov, David Lundgren, Honza Král, James Reynolds, Jannis Leidel, Juan Ignacio Catalano, Kevin Stone, Mathieu Pillard, Mihnea Dobrescu-Balaur, nearlyfreeapps, Ricky Cook, Rob Hudson, William Tisäter and Will Kahn-Greene.

We're going to be sprinting on ElasticUtils 0.10 at PyCon US in Montreal mid April. If you're interested, come find me!

If you have any questions, let us know! We hang out on #elasticutils on irc.mozilla.org.

pyvideo status: February 15th, 2014

What is pyvideo.org

pyvideo.org is an index of Python-related conference and user-group videos on the Internet. Saw a session you liked and want to share it? It's likely you can find it, watch it, and share it with pyvideo.org.

Status

Over the last year, a number of things have led to a tangled mess of tasks that need to be done that were blocked on other tasks that were complicated by the fact that I had half-done a bunch of things. I've been chipping away at various aspects of things, but most of them were blocked on me finishing infrastructure changes I started in November when we moved everything to Rackspace.

I finally got my local pyvideo environment working and a staging environment working. I finally sorted out my postgres issues, so I've got backups and restores working (yes--I test restores). I finally fixed all the problems with my deploy script so I can deploy when I want to and can do it reliably.

Now that I've got all that working, I pushed changes to the footer recognizing that Sheila and I are co-adminning (and have been for some time) and that Rackspace is graciously hosting pyvideo.

In the queue of things to do:

  • finish up some changes to richard and then update pyvideo to the latest richard
  • re-encode all the .flv files I have from blip.tv into something more HTML5-palatable (I could use help with this--my encoding-fu sucks)
  • fix other blip.tv metadata fallout--for example most of the PyGotham videos have terrible metadata (my fault)
  • continue working on process and tools to make pyvideo easier to contribute to

That about covers it for this status report.

Questions, comments, thoughts, etc--send me email or twart me at @PyvideoOrg or or @willcage.
