Need a new buffer opened - call macro example

[TKasparek]

Can someone point me to an example or explain how I can have a macro called when a new buffer is opened? I have a macro that requires setup for each buffer and located in the per-buffer data area using _GetBufferInfoHtPtr. I have a fast macro that needs to be called that validates a buffer is of a certain type and installs the correct settings via  _SetBufferInfoHt(). The problem that is currently I need to do the setup/SetBuffer.. step manually. I would like this to be done automatically (as well as automatically update menu item settings for it). But I need a system callback that will call my setup macro first. Any thoughts?

Search slick macro sources for call_list - you get the results below.  call_list calls all of the functions whose name starts with the specified prefix.  So
call_list('_buffer_add_',p_buf_id,p_buf_name,p_buf_flags);
calls all the functions whose name starts with _buffer_add_
So if you search slick sources for _buffer_add_ you'll find this - among other things
void _buffer_add_tabs(int newbuffid, _str name, int flags = 0);
All the _buffer_add_ functions get called when a new buffer is opened.

There's also _switchbuf_  - functions that get called when you switch to a different buffer.
You can iterate through open buffers using the for_each_buffer function.

How did you find out about  _SetBufferInfoHt() ?

Thanks! A _buffer_add_ function is exactly what I was looking for. I'm surprised this functionality isn't documented in the SE Help. A search indicates it's referenced only once with a very loose example.

I did a lot of SE macros investigation when making a macro I call RegexColor. It uses a lot of the concepts from the SE SymbolColorAnalyzer; I'm pretty sure I first discovered *BufferInfoHt functionality there. It's also documented a bit in the help if you search for it by name.

Do you know how to get a callback for when the buffer window is scrolled or changes size? Currently, I run a timer to look for a change in the buffer window position to re-color if outside of the colored line ranges. This functionality would also be very useful.

[Bamsen]

How do you add a _buffer_add_ function and include it in the list of functions to be called?

[Graeme]

How do you add a _buffer_add_ function and include it in the list of functions to be called?

Like this
void _buffer_add_water(int newbuffid, _str name, int flags = 0)
{
    say("buffer is " :+ name);
}
That's all you have to do.  Because the function name starts with _buffer_add_ it is called automatically.  Slick has a thing called a "names table" - search for "names table" in the help.  The names table allows slick to search (at runtime) for all functions whose name starts with a particular prefix.  Slick macro code uses late binding where all function calls to macro code go via the names table.  This allows you to reload a macro file and have all the rest of the already compiled macro code still call the functions in your newly loaded module without themselves being recompiled.
