Storing lists of tokens

LaTeX3 separates out macros which do something (functions) from those used to store information. As has been pointed out to me, the later are lists of tokens not characters. TeX already provides us with toks (token registers), and so LaTeX3 calls macros that store token lists “token list pointers”. There’s been some discussion recently about this name, and Will Robertson has suggested just “token lists” would be better. I quite like the idea (pointers makes it sound like some low-level memory thing), but I’m not sure if the team will go for it.

TeXworks for package authors

The TeXworks project is targetted at making life easier for new users of TeX. The clean, Mac-inspired interface certainly makes writing TeX documents very easy, as does the buit-in PDF viewer with SyncTeX ability. As a long time user of a more “traditional” editor (WinEdt), I’ve found that TeXworks is good for all of my editing, to the point that I’m not longer using WinEdt. The parred-down feature set really suits my way of working (I’ve never liked all of the editor icons in a traditional IDE), and even at this pre-release stage the advanced features (such as regex searching) are impressive.

Toward siunitx 2

My siunitx package has attracted a lot of attention, and I’ve had a lot of requests for new features. To get these working, I’m having to re-code the package from the ground up. There are lots of problems with the code as it stands, as it is cobbled together from the previous packages in many cases.

So far, I’ve recoded the system that parses numbers, taking out a lot of the loops and making it hopefully much faster. I’ve also got about half of the table system redone: this collects up the table contents in a more efficient (and intelligent) manner than the old code. The next step is to look at the output formatting system, where I have several ideas to make everything smoother.

One area that I’m keen to improve is the user options. The current system is too complex, so I’m looking at doing something tree-based. The options are all being divided into groups, which should make things easier to follow.

Another area for lots of attention is table output. This seems to be the thing that I get most questions about. Lots to work on there, but so far nothing is done. I need to look over all of the suggestions I’ve had and find a way to please everyone (not easy).

Some TeX Developments

Where to start? Writing a blog on what is going in with my own (La)TeX development, and what is happening in the TeX world, seems like a handy thing to do. For my own packages (for example siunitx) it would be nice to give an insight into what is going on with the code, and where I am currently working. In the wider TeX world, there are things I’ve taken an interest in (such as TeXworks and LaTeX3) which I can make the odd comment on. There might even be some non-TeX stuff here, but I’ll see (focus is the key, and all that).
