If you work with bazaar, you have seen its URIs. You can find the complete list is in the bzr help urlspec. Although I commonly use only a subset of that, like bzr+ssh://bazaar.launchpad.net/~maria-captains/maria/5.2-serg/ and http://bazaar.launchpad.net/%2Bbranch/mysql-server/5.5/.

In addition I often use Launchpad aliases, such as lp:~maria-captains/maria/5.3-serg/, lp:maria/5.3, and lp:869001.

And finally, there are common abbreviations that we have used in MySQL, and others that we use in MariaDB, for example bug#12345 and wl#90.

What’s annoying, I need to remember that wl#90 corresponds to http://askmonty.org/worklog/?tid=90 and type the latter in the location bar of the browser, when I want to look this task up. And lp:869001 is, for my browser, https://bugs.launchpad.net/bugs/869001. Similarly, every other URL above, has its browser-friendly evil twin. It’s evil, because I have to remember it!

Now, Firefox tries to help, to a certain extent. It supports so-called keywords — short aliases for bookmarks. Create a bookmark for https://bugs.launchpad.net/bugs/%s and in the Keyword field enter lp. Now you can type in the location bar lp 869001 (with a space) and Firefox will expand it into a complete url https://bugs.launchpad.net/bugs/869001. Quite handy. And I’ve used it for a few years. Still it annoyed me, that I had to rewrite the abbreviations manually, put spaces, remove colons, and so on. And at last it annoyed me to a degree where I wrote a Firefox plugin!

For many years I was using tcsh, with lots of useful customizations, that were created during these years. Now I have bash on my laptop and slowly adding what I’ve got used to.

Yesterday I’ve created command line completion rules for mysql-test-run. It’s not a complete set of everything that’s possible, still it’s quite useful as it is. I need to type much less now when invoking mysql-test-run (and I invoke it quite a lot).

I don’t know about you, but I like diff -p [1].  Having used it for years, I can read these diffs like a text, while diffs without -p often need to have the original file opened side by side, just to get enough of the context.

Loving diff -p so much, I want to see it everywhere (evil laughter). Alas, in bzr only diff command can easily use -p, just run it as bzr diff --diff-options=-p or store it as an alias in the ~/.bazaar/bazaar.conf.

Actually, for an alias there is a better, although more verbose, alternative:

Unlike simple -p it will not think that a word ending with a semicolon (like a label or, say, public: and private:) is a “C function name”.

But the problem is — only bzr diff can be tuned this way. Bzr email plugin still sends diffs without function names. And bzr gdiff does not show them. And, of course, all other bzr commands — bzr commit, for example, or bzr shelve, bzr unshelve --preview, bzr log --show-diff and others — they are still as unfriendly as before.

I was solving it on a case by case basis — added a post_commit_diffoptions configuration option to the bzr-email plugin, then a command line option to bzr gdiff. But then it occurred to me that I can attack the problem at its core!
