Re: [galaxy-dev] Suggestion / Request for Comments on Galaxy Best Practices - Gradual migration to standard indentation
Coding standards have been discussed before, but perhaps never written down. So, here is my interpretation: We follow PEP-8, with particular emphasis on the parts about knowing when to be inconsistent, and readability being the ultimate goal. In addition, we make the following specific exceptions: Line length: comments and documentation comments should follow the 79 character rule, other lines should be formatted for readability, recognizing the existence of wide screens and scrollbars (sometimes a 200 character line is more readable, though rarely). Spacing: whitespace around operators and inside parentheses et al. is okay, particularly if it helps readability. We are widely inconsistent on this, if the thing inside the parentheses is short (a single word) often spaces are extraneous, if it is a complex expression, spacing helps to delineate different parts. Blank lines: also subjective, the size of the class, number of methods, size of methods, et cetera all influence what sort of spacing is most readable. This subjectivity makes it very hard to run a systematic check for spacing and line length deviations. The more obvious things like tabs used for indentation are bugs.

Re: [galaxy-dev] Suggestion / Request for Comments on Galaxy Best Practices - Gradual migration to standard indentation
Hello all, I've created a wiki page on coding best practices to record what is actually done, and the results of discussions like these: http://wiki.g2.bx.psu.edu/Develop/Best Practices So far, it only lists 2 standards: 1. 4 spaces per indent level 2. Use spaces, not tabs. I'll continue to watch this list and add best practices accordingly.

I'm unsure whether repository hooks are stored on github, but they are definitely ignored (only specific post-receive hooks are allowed, and these are set up via the github admin API). With git the only way I can think of to set something like this up is client-side (pre/post-commit, or pre-push), then maybe have a separate post-checkout hook to set everything up after a clone. I assume hg has a similar mechanism. chris ___ Please keep all replies on the list by using "reply all" in your mail client.

It is the Galaxy Team's intent to use four-space indents, anything else is a mistake and we try to fix 'em as we see 'em. Nobody has yet taken the time to fix them all (i.e. with reindent.py) but such fixes would be welcome. > Personally I'd like to go further and fix the non-PEP8 white > space in most of the Galaxy Python code, e.g. > > function ( argument ) > > rather than: > > function(argument). There are a lot of parts of PEP 8 that I doubt we want to adhere to strictly. I agree it's annoying to find varying styles, but the space inside parentheses is not one I get too worked up about. FWIW, I prefer function( argument ) and I tend to see that style out of most of the rest of the team. > Chatting to some of the Galaxy team at BOSC/ISMB 2011 > there is some support for this internally.

But not essential. We can't add custom hooks to the bitbucket repository and we don't have an intermediate local repository that we all push changesets through. --nate > > Peter > > ___ > Please keep all replies on the list by using "reply all" > in your mail client.

Doing this in chunked commits makes good sense too - although if you can get one of the Galaxy team to do this directly it might be quicker. Personally I'd like to go further and fix the non-PEP8 white space in most of the Galaxy Python code, e.g. function ( argument ) rather than: function(argument). Chatting to some of the Galaxy team at BOSC/ISMB 2011 there is some support for this internally. Again, there are automated tools to do this. > would anyone be willing to add the appropriate hooks to > the central repository as well? As long as there are no false positives identified during the initial tab/space conversion that seems sensible to prevent new tabs creeping in. But not essential.
