Hi All,

1. Is it possible to easily get the start addresses
   of all basic blocks?(I know pida script does it but
   is't there a simple way to enumerate basic blocks?)
2. Is it possible to color ida basic blocks using ida
   python?

thx,
  stam

A way of doing this could be by first getting all the addresses of code belonging to a function: # Collecting function chunks function_instructions = list() # Get the tail iterator func_iter = func_tail_iterator_t(get_func(ea)) # While the iterator's status is valid status = func_iter.main() while status: # Get the chunk chunk = func_iter.chunk() # Go through all instructions in the basic block # and add them to our list # for head in Heads(chunk.startEA, chunk.endEA): if isCode(getFlags(head)): function_instructions.append(head) # Get the last status status = func_iter.next() Then, for each of the addresses we check if there're outgoing references and add them to our set of possible basic block start addresses: `basic_blocks = set() for address in function_instructions: refs_from = CodeRefsFrom(address, 1) if len(refs_from)>1: basic_blocks.update(refs_from)` After we collect those, we clean up the list leaving only references pointing within the function: `basic_blocks = filter(lambda i: i in function_instructions, basic_blocks) print map(hex, basic_blocks)` And that's the list of start addresses of the basic blocks. The only problems that i foresee could arise in highly optimized code if IDA did not properly assign all function chunks to the function, but for most cases it'll do just fine. Hope this helps,

Thanks. This is almost the code i used already. I hoped there is a simpler way :)

Hello All I'm trying to download IDAPython v0.8.0 plugin but it seems like the download link is broken any one can post a link to a mirror or some thing.

This is the official site, the links should work there.

I meant to respond to this sooner, but better late than never. Here is a simple function I use to color from IDA Python: `def color_block (bb, color): ''' color = 0xBBGGRR use DEFCOLOR to remove coloring ''' for ea in Heads(bb.ea_start, bb.ea_end): SetColor(ea, CIC_ITEM, color)` The only non-straight forward portion of which is that IDA handles color in BGR vs. RGB.

> ero: This is the official site, the links should work there. ero , something must be wrong with your Server , because i'm having trouble too , domain name doesnt even resolve but using an American web proxy its available . i had this problem once before but never told you thought its only me now i see others have this problem . btw i realized me and the other guy who had problem both reside on ME area , does it make any sense ? ( sorry to interrupt with off topic post )

It's not my site/server so unfortunately I can't do much else than pinging the owner.

I made a quick mirror of the latest IDA Python here: http://www.openrce.org/ida_python/ Until the original site becomes accessible. Try the latest version and see if the SetColor() routine works for you, it should.

SetColor dont work for me as well.
