Yakov On some systems that answer is correct. On others it is not. :-) I'm aware of binary numbers in perl (0b101010101). But in C ? What exactly is syntax of binary numbers in C ? How does it look ? On which systems ? I never heard of binary numbers in C ... I am very curious to hear from you all details that you can provide. What exactly are those systems and how exactly the syntax looks ? Yakov Since I've been working with computers since the early 1970s and since I used B (the predecessor of C which was [and possibly still is] used in Canada), it is more than most likely that I am mixing and matching my languages or remembering an outdated version of C. Also, since at NASA (I was at NASA JSC in ClearLake/Houston) we had to do a lot of our own coding for various items (like a control chair so simulations could be done with the astronauts, or the fixed and motion based simulators, etc...) it is also likely that I was using macros someone else wrote to allow for binary input of numbers. (This was necessary in some cases because the hardware would only accept binary information some times. In many cases we would do inline assembly language within the C programs too.) The 70's and even the 80's were a dark time in computer programming because there were very few standards and not a lot of company's used them. (This is one of the really few things that Microsoft and Apple Computer helped to change. They do try to enforce the standards - on everyone else of course. Even though it seems they both also break their own standards every chance they get.) Like SGI which had it's own special interface for their graphic computers until X-Windows came along and then SGI switched to Linux as their OS basis. There were some special items to SGI's C to help handle the graphics in the pre-X-Windows days. Things became more standardized with X-Windows and then the Linux OS helped out even more. So take your pick. Don't really care. But there probably are still systems out there that have binary capabilities in their C languages to help out with whatever. Check out Sony's PlayStation 3. People are having to write very low-level code to get it to work. Makes me wonder if people are using C and if those compilers have special additions to them that would allow someone to write binary information directly to a part of the hardware to help boost the speed of it. If so, they might extend the C language via macros or a direct change to the compiler in order for everyone to get the most out of the computer. Still, I'm not going to rack my brain for exactly which system and where just because you want to know. It is not worth the time or effort on my part. Have fun! :-) Mark I suppose that with inline assembly, assembly-language syntax blocks could be included within C syntax (like mzscheme, perl, python, ruby and tcl syntax blocks within vim syntax) but that should be handled by the appropriate assembly-language syntax script, which ought to allow (e.g., for MASM) 11010011B (binary), 0D3H (hex), 343O or 343Q (Octal; my memory is failing) as well as 211D (decimal) and 211 (decimal by default) as synonymous; IIRC it also has floating-point numbers in decimal-point or exponential notation for use with the arithmetic coprocessor. Best regards, Tony.
Anim8or scripting language.
There is a free, but not open source, 3d modelling package called
Anim8or at http://www.anim8or.com/ which, in the new beta release
has a scripting language. Anim8or also has modelling files, so
there are really two different syntaxes associated with this.
The modelling files are something I have not tried to make Vim
support, so in the attached patch I have named the file a8s.vim
rather than anim8or.vim.
The patch is a clumsy hack (with a blunt instrument, so to speak) at
the C syntax file, to get it to support the a8s syntax. It is definitely
buggy:
#parameters(this,
that,
the other)
fails with a syntax error on the last bracket and the colouring for
it doesn't work as I'd expect from hacking the #define directive in
C. That may not even be the right approach, given the semantics.
I tried to provide support the highlighting $variables, but couldn't
understand how this was done in perl.vim or sh.vim to get it right,
so I've left that for now.
Anyway, I'm putting this forward in the hope that someone more fluent
in vim scripting, syntax, etc can [help me?] make something presentable
out of it, and the hope that others find it of some use.
I've created a small web page about this at
http://www.eng.cse.dmu.ac.uk/~hgs/anim8or/
from which you can get the attached patch and the syntax file itself.
Thank you,
Hugh

From the description of what it does, fnamemodify() _seems_ to involve
only string manipulation, possibly checking $HOME and/or the current
window's current directory depending on the {mods} argument. There may
be one OS call on Unix or VMS if ~user/ (not just ~ which is $HOME) is
used in conjunction with :p.

Is fnamemodify() an expensive operation involving OS calls? It depends on what you are doing, what the file name is and what system you are on. Mostly for turning a relative name into a full path an OS call is needed. You'll have to try it out. -- Q: What do you call a fish without an eye? A: fsh! Q: What do you call a deer with no eyes?

That is what I was hoping. At least for simple modifications not
involving special character expansion, it is probably simple string
manipuations and will not be expensive.

Bug or feature? CursorLine/CursorColumn hihlights vs. other highlights
I have enabled CursorLine and CursorColumn highlights as follows: (~/.vimrc): [...] colorscheme almost-default [...] if exists(+cursorcolumn) set cuc cul endif [...] (~/.vim/colors/almost-default.vim): [...] if has(gui_running) hi clear CursorLine hi CursorLine guibg=#F4F4F4 leave it underlined (default) in cterm endif hi clear CursorColumn hi link CursorColumn CursorLine [...] However, I notice that their interaction with other highlights is not always the same, even though they are linked to each other: all the following is in the GUI: - most syntax highlights change only the foreground, which is respected; - a few, for instance helpNote (linked to Todo) and htmlError (linked to Error), change the background, which is changed to pale grey on both the cursor line and the cursor column; - neither the status line, the (text-style) tab line, nor text in another window than the current one, are affected. I suppose the above can be regarded as normal. But: - Search highlight sets the background to yellow; this is changed to pale grey on the cursor column but not on the cursor line; - SpecialKey sets the foreground to blue and NonText sets it to bold blue: these are changed to unbold and bold black (respectively) on the cursor line but not on the cursor column. The fact that in these cases, highlights linked to each other do not behave identically, strikes me as weird. Bug or feature? Best regards, Tony.
patch: automatically enter paste mode
Pasting code into vim and forgetting to set paste can have annoying
results. This patch detects the 'really fast typing' that happens when
something is pasted in, and turns on paste mode. It provides an option
'autopaste' (default false) which controls the behavior.
Patch is attached. Hope this is useful.
