 00:18:03.760 --> 00:18:13.039
-so we copy the pattern

-00:18:13.039 --> 00:18:18.640
-and we add this pattern

-00:18:18.640 --> 00:18:25.120
-pop item only
+So we copy the pattern,
 
-00:18:25.120 --> 00:18:28.400
-but we also want to give the

-let's say we want to highlight it as a

-the highlighting patterns can also be

-00:19:23.440 --> 00:19:26.880
-for example let's take a look at
+00:19:23.440 --> 00:19:35.760
+For example, let's take a look at

-ems source code
+00:19:35.760 --> 00:19:41.123
+So in Emacs's C source,
+there are a lot of uses
 
-00:19:35.760 --> 00:19:40.400
-so in image c source there are a lot of
-
-00:19:40.400 --> 00:19:43.760
-uses of these different macros
+00:19:41.123 --> 00:19:43.760
+of these different macros
 
 00:19:43.760 --> 00:19:47.679
-to define functions
-
-00:19:47.679 --> 00:19:51.200
-and you can see
-
-00:19:51.200 --> 00:19:53.520
-this is actually the function name but
+to define functions,
 
-00:19:53.520 --> 00:19:55.760
-it's highlighted as the
+00:19:47.679 --> 00:19:53.256
+and you can see this is actually
+the function name,
 
-00:19:55.760 --> 00:19:59.120
-string so what we want
+00:19:53.256 --> 00:19:56.373
+but it's highlighted as the string.
 
-00:19:59.120 --> 00:20:03.679
-is to somehow recognize this pattern
+00:19:56.373 --> 00:20:03.679
+So what we want is to somehow
+recognize this pattern
 
 00:20:03.679 --> 00:20:07.600
-and highlight it
+and highlight it.
 
 00:20:07.600 --> 00:20:11.280
-as highlight this part

 00:20:11.280 --> 00:20:14.559
-with the function phase instead

 00:20:14.559 --> 00:20:17.679
-in order to do that
-
-00:20:17.679 --> 00:20:20.240
-we put a pattern in this project
-
-00:20:20.240 --> 00:20:21.760
-directory local

+In order to do that,
 
-00:20:31.760 --> 00:20:34.799
-so we can put this button in the c
+00:20:17.679 --> 00:20:31.760
+we put a pattern in this project's

-mode section
+00:20:31.760 --> 00:20:40.159
+So we can put this button in

 00:20:40.159 --> 00:20:48.000
-and now if we enable tree sitter
+And now, if we enable tree-sitter,
 
 00:20:48.000 --> 00:20:50.480
-you can see that this is the highlighted

-uh
-
-00:20:53.200 --> 00:20:55.520
-as a normal function definition so this
-
-00:20:55.520 --> 00:20:56.559
-is the function
-
-00:20:56.559 --> 00:21:01.200
-face like we wanted
-
-00:21:01.200 --> 00:21:03.760
-the pattern for this is actually pretty
+you can see that this is highlighted
 
-00:21:03.760 --> 00:21:07.200
-simple
+00:20:53.200 --> 00:20:55.056
+as a normal function definition.
 
-00:21:07.200 --> 00:21:10.720
-it's only
+00:20:55.056 --> 00:21:01.200
+So this is the function face
+like we wanted.
 
-00:21:10.720 --> 00:21:14.720
-only this part so
+00:21:01.200 --> 00:21:07.200
+The pattern for this is
+actually pretty simple.
 
-00:21:14.720 --> 00:21:17.440
-if it's a function call where the name

+It's only this part.
 
-00:21:17.440 --> 00:21:19.679
-of the function is different
+00:21:12.373 --> 00:21:16.456
+So if it's a function call
 
-00:21:19.679 --> 00:21:21.600
-then we highlight the different as a
+00:21:16.456 --> 00:21:19.679
+where the name of the function is
+defun,
 
-00:21:21.600 --> 00:21:24.240
-keyword
+00:21:19.679 --> 00:21:24.240
+then we highlight the defun as a
+keyword,
 
-00:21:24.240 --> 00:21:27.360
-and then the first string element we
+00:21:24.240 --> 00:21:26.923
+and then the first string element,
 
-00:21:27.360 --> 00:21:28.159
-highlighted
+00:21:26.923 --> 00:21:35.360
+we highlight it as a function name.
 
-00:21:28.159 --> 00:21:35.360
-as a function name
+00:21:35.360 --> 00:21:39.280
+Since the language objects are actually
+native code,
 
-00:21:35.360 --> 00:21:37.679
-since the language objects are actually
+00:21:39.280 --> 00:21:41.459

-they have to be compiled for each
