TeXworks is a very flexible editor, and one of the things you can customise, if you want, is the set of auto-completion values it knows. For those of you who are not familiar with it, TeXworks uses a simple list of simple completion options, so when I type
I can press the Tab key and be offered
and if I press Tab again,
That’s very useful, but some of the auto-complete options are not ones I use a lot. There are also a few inconsistencies in how the results are formatted: while TeXworks inherited a basic set from TeXShop, it also comes with some additions and they don’t always quite agree on how things should work! So I’ve been looking a bit at sorting out my own custom set, adding things I use, removing ones I don’t and so on.
The basic format for the auto-complete files is to have a first line for the encoding
%% !TEX encoding = UTF-8 Unicode
then one or more lines for each completion. Each line can either just have a completion vale
or have a ‘shortcut’ text version
There are then a few bits of ‘helper’ syntax. You can use
#INS# to show where the cursor should end up,
#RET for a return and
• as a marker you can jump to using Ctrl-Tab (Option-Tab on the Mac). So for example the
\documentclass lines read
I’m told that TeXShop has extended the syntax a bit, but at least at the moment in TeXworks that all there is to know.
So what have I done to customise the files? TeXworks comes with four auto-complete files, but the values offered simply come from them all together (you can’t currently select only some files). (You might wonder where these files live: they are ‘hidden away’: TeXworks will tell you how to find them from Help -> Settings and resources.) So my first move was to create one new file, after first backing up the originals of course! I then did a few experiments, thinking about what I use a lot, what I’m used to, etc. I did wonder about some of the choices in the standard files, but a bit of experimentation suggests they are not so bad! So I’ve currently ended up mainly just adding a few things, for example
for TikZ pictures and
for package development work. I’m also not too keen on having too many of the ‘shortcut’ values, which don’t start
\, so I’ve removed most of them and have just a core set (things like
em). If you want to see my current full set, you can of course download it.
So is there anything I’d like to see added to the way auto-complete works? I have a few ideas! From my questions on the TeXworks mailing list, I’ve picked up that TeXShop maintains indentation when doing auto-complete: TeXworks doesn’t, and I think it would be a good addition. TeXShop also allows an extended syntax
where you can always have a
• for ‘fill in’ and have ‘reminders’ about what the values are. That looks useful too.
