This is not a copy of this question: How to highlight text in a tkinter Text widget. It's more of a continuation. From This Question, I got this code:
class CustomText(tk.Text):
'''A text widget with a new method, highlight_pattern()
example:
text = CustomText()
text.tag_configure("red", foreground="#ff0000")
text.highlight_pattern("this should be red", "red")
The highlight_pattern method is a simplified python
version of the tcl code at http://wiki.tcl.tk/3246
'''
def __init__(self, *args, **kwargs):
tk.Text.__init__(self, *args, **kwargs)
def highlight_pattern(self, pattern, tag, start="1.0", end="end",
regexp=False):
'''Apply the given tag to all text that matches the given pattern
If 'regexp' is set to True, pattern will be treated as a regular
expression according to Tcl's regular expression syntax.
'''
start = self.index(start)
end = self.index(end)
self.mark_set("matchStart", start)
self.mark_set("matchEnd", start)
self.mark_set("searchLimit", end)
count = tk.IntVar()
while True:
index = self.search(pattern, "matchEnd","searchLimit",
count=count, regexp=regexp)
if index == "": break
if count.get() == 0: break # degenerate pattern which matches zero-length strings
self.mark_set("matchStart", index)
self.mark_set("matchEnd", "%s+%sc" % (index, count.get()))
self.tag_add(tag, "matchStart", "matchEnd")
This code works very well tho I am running into an issue. I actually want to use this highlight feature in my python editor's color coding. The problem is that whenever I use this, I need it to color up words but it colors the letters up anywhere it finds it, even when its in other words. (For Example: When I try to highlight the word "on", the "on" in the word "one" will also color up) Can anyone please modify this code for me, so it only colors up words.
