Snippets for functions with optional arguments

[gregor.hoch]

Hi, I has just looking at the documentation for snippets and started wondering whether they somehow support optional arguments for functions?

For example, when I implement

Code: Select all

lm(formula, data, subset)

as a snippets, the content would look like this

Code: Select all

<content><![CDATA[lm(${1:formula}, ${2:data}) , ${3:subset})]]></content>

But data and subset are optional options (only formula is required). What is the best way to handle this situation with snippets. Is there a way to indicate that parts are optional so that they are not inserted by default but only come up for autocompletion within the function?

Thanks!

The most common way to handle this is with square brackets like so:

<content><![CDATA[lm(${1:formula} ${2:[, data]}) ${3:[, subset]})]]></content>

So I guess there is no way to have an auto-completion based on function arguments within snippets? So that ST2 basically offers the function arguments as completion options as part of the snippet (or through a different mechanism)?

thanks!

I'm on a roll with people requesting features that I've already incorporated into my plugin.

@gregor: no this is not possible with by default in ST. However, I'm currently developing a plugin that extends the snippet functionality and this will be possible. Unfortunately it still has a lot of work to get done; however, I may open it up to the public soon. Stay tuned!

sounds absolutely great! I would be happy to contribute extended snippets for R...

So how is this plugin going on?

Is it possible to handle optional parameters already?
