Can you guarantee that your function names are absolutely unique text
strings? If so, grep can do what you want. I don't have a huge Python
project to demo this on, but grep is language-agnostic.
rosuav@sikorsky:~/Gypsum$ grep gtksignal *.pike plugins/*.pike
globals.pike://Usage:
gtksignal(some_object,"some_signal",handler,arg,arg,arg) --> save that
object.
globals.pike:class gtksignal(object obj)
globals.pike: mi->signals=({gtksignal(mi->menuitem,"activate",menu_clicked)});
globals.pike: mi->signals=({gtksignal(mi->menuitem,"activate",menu_clicked)});
globals.pike: //a gtksignal object or the integer 0, though as of
20150103 nothing depends on this.
globals.pike: gtksignal(win->mainwindow,"delete_event",closewindow),
globals.pike: win->stock_close &&
gtksignal(win->stock_close,"clicked",closewindow),
globals.pike:
win->signals+=({gtksignal(obj,parts[i+1..]*"_",this[key],arg,UNDEFINED,b4)});
globals.pike: if (actionbtn)
win->signals+=({gtksignal(win->pb_action,"clicked",action_callback)});
globals.pike:
statustxt->signals=({gtksignal(statustxt->evbox,"button_press_event",mousedown)});
window.pike: //an additional argument to signal_connect/gtksignal
would provide that value here)
plugins/hpgraph.pike:
win->signals+=({gtksignal(win["color"+j+i],"clicked",update_color,i)});
plugins/hpgraph.pike:
info->signals=({gtksignal(info->evbox,"button_press_event",mousedown)});
plugins/rmimport.pike:
gtksignal(win->pb_selectall,"clicked",pb_select_click,1), //Same
handler for these, just an arg
plugins/rmimport.pike:
gtksignal(win->pb_selectnone,"clicked",pb_select_click,0),
//Technically, since the default is 0, I could call this
sig_pb_selectnone_clicked, but this way is clearer.
plugins/search.pike:
statustxt->signals=({gtksignal(statustxt->ef,"key_press_event",keypress,0,UNDEFINED,1)});
plugins/zoneinfo.pike:
win->signals+=({gtksignal(win[pfx+"_"+sfx],"changed",pfx=="Thresh"?convert_th:convert_rl,pfx)});
Each of those lines is one usage of the gtksignal() class/function.
One of them is actually a comment (in window.pike), and the first two
at the top of globals.pike are the class definition, with an
associated usage comment, but all the rest are actual uses. As long as
you can depend on names like roll_dice not occurring anywhere else,
this is a great way to find out what you need to know.
If you _can't_ rely on that, it's a bit harder. You could possibly
append an open parenthesis to it, to require classic function-call
syntax, but that may not necessarily be enough (depends how strict
your style guide is). You can do lexical analysis of a Python program
to see where the name is used in a function call, which might be
better. Or you could instrument the function to find out where it's
being called from, and then run every program and see how many of them
call it - something like this:
def pick_card():
import __main__
print("Called from %s"%__main__.__file__)
# rest of pick_card's definition
Log that to a file instead of the screen, and you have yourself a
guaranteed log that shows which programs use that function. Of course,
that depends on actually running the program far enough to get to the
call, which might require interaction.
Depending on your requirements, it could be anywhere from easy to
hard. Good luck :)
