<div><br></div><div>There are instructions for building and running in the doc/ directory.</div><div><br></div><div><a href="http://llvm.org/svn/llvm-project/llbrowse/trunk/"></a>First task if someone wants to take it on - update all of the source files to have the <meta http-equiv="content-type" content="text/html; charset=utf-8"><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; font-size: 13px; ">UIUC license info at the top, and add a LICENSE.txt file :)</span></div>

<div><ul><li><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; ">Update the status bar when a module is loaded (currently says "no module loaded")</span></li><li><font class="Apple-style-span" face="arial, sans-serif"><span class="Apple-style-span" style="border-collapse: collapse;">Add support for command-line parameters - you should be able to specify a module file on the command line and have it load it on startup.</span></font></li>
<li><font class="Apple-style-span" face="arial, sans-serif"><span class="Apple-style-span" style="border-collapse: collapse;">Change the subversion property for the HTML files in the doc directory to have the proper mime type.</span></font></li>
<li><font class="Apple-style-span" face="arial, sans-serif"><span class="Apple-style-span" style="border-collapse: collapse;">Add new icons for different DIE types (currently all DWARF nodes use the same icon.) Note that you need to re-run CMake after adding a new icon so it can create the dependency rules for converting the icon data to a C header file. Icons are always 20x20 and can easily be created in GIMP.</span></font></li>
<li><font class="Apple-style-span" face="arial, sans-serif"><span class="Apple-style-span" style="border-collapse: collapse;"></span></font><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; ">Add a "search" function that allows searching for a symbol by name. (This one's not trivial due to the lazy construction of tree nodes. Basically what it needs to do is walk the tree (avoiding cycles), and call treeCtrl->SelectItem and treeCtrl->EnsureVisible on the node whose caption contains the search string. I have some notes on how to do this.)</span></li>
<li><span class="Apple-style-span" style="border-collapse: collapse; font-family: arial, sans-serif; ">Make sure the app isn't leaking memory when loading a new module over an old one.</span></li></ul><div><font class="Apple-style-span" face="arial, sans-serif"><span class="Apple-style-span" style="border-collapse: collapse;">In the mean time, I'll be working on getting DWARF derived type DIEs to display as much information as possible... :)</span></font></div>
