Ubuntu_Gedit配置

Ubuntu_Gedit配置

• 为了换Ubuntu的时候能够更加方便，不用再用手重新打一遍代码，丢几个Gedit配置……

External Tools

1. gdb compile (F2)

   #!/bin/sh
   fullname=$GEDIT_CURRENT_DOCUMENT_NAME
   name=`echo $fullname | cut -d. -f1`
   g++ -o $name $fullname -g -Wall -Wextra -D LOCAL
   gnome-terminal -x bash -c "gdb $name -silent;echo 'Nobody knows you better than I know...';read"
   

2. compile (F3)

   #!/bin/sh
   fullname=$GEDIT_CURRENT_DOCUMENT_NAME
   name=`echo $fullname | cut -d. -f1`
   g++ $fullname -o $name -Wall -Wextra -D LOCAL -fsanitize=address
   

3. run (F4)

   #!/bin/sh
   fullname=$GEDIT_CURRENT_DOCUMENT_NAME
   name=`echo $fullname | cut -d. -f1`
   dir=$GEDIT_CURRENT_DOCUMENT_DIR
   gnome-terminal -x bash -c "time $dir/$name; echo;echo 'Nobody knows you better than I know...';read"
   

Snippets

1. fast read (Ctrl+R)

   namespace IO {
   	const int N=1<<20;
   	char buf[N],*l=buf,*r=buf;
   	inline char gc() {
   		if(l==r) r=(l=buf)+fread(buf,1,N,stdin);
   		return *(l++);
   	}
   	inline int read() {
   		int x=0,s=1;
   		char ch=gc();
   		while(!isdigit(ch)) {if(ch=='-') s=-1;ch=gc();}
   		while(isdigit(ch)) {x=x*10+(ch^48);ch=gc();}
   		return x*s;
   	}
   	template <typename T> 
   	inline void read(T &x) {
   		int s=1;x=0;
   		char ch=gc();
   		while(!isdigit(ch)) {if(ch=='-') s=-1;ch=gc();}
   		while(isdigit(ch)) {x=x*10+(ch^48);ch=gc();}
   		x*=s;
   	}
   	inline char readc() {
   		char ch=gc();
   		while(ch<=32) ch=gc();
   		return ch;
   	}
   	inline int reads(char *s) {
   		char *point=s;*point=gc();
   		while(*point<=32) *point=gc();
   		while(*point>32) *(++point)=gc();
   		*point='\0';
   		return point-s;
   	}
   }
   

   • 在单位字符串长度大于 \(30\) 的时候，scanf 的效率会高于 reads 。

   • ch>32 貌似比 isalnum(ch) 和 ch!=' '&&ch!='\n' 要快一点。

2. fast basic code (Tab:include,Ctrl+B)

   #include <iostream>
   #include <cstdio>
   
   namespace IO {
   	const int N=1<<20;
   	char buf[N],*l=buf,*r=buf;
   	inline char gc() {
   		if(l==r) r=(l=buf)+fread(buf,1,N,stdin);
   		return *(l++);
   	}
   	inline int read() {
   		int x=0,s=1;
   		char ch=gc();
   		while(!isdigit(ch)) {if(ch=='-') s=-1;ch=gc();}
   		while(isdigit(ch)) {x=x*10+(ch^48);ch=gc();}
   		return x*s;
   	}
   }
   
   using namespace std;
   using IO::read;
   
   int main() {
   #ifdef LOCAL
   	freopen("c.in","r",stdin);
   	//freopen("c.out","w",stdout);
   #endif
   	$0
   	return 0;
   }
   
   // by pycr
   

3. read (Ctrl+Shift+R)

   inline int read() {
   	int x=0,s=1;
   	char ch=getchar();
   	while(ch<'0'||ch>'9') {if(ch=='-') s=-1;ch=getchar();}
   	while(ch>='0'&&ch<='9') {x=x*10+(ch^48);ch=getchar();}
   	return x*s;
   }
   

4. basic code (Ctrl+Shift+B)

   #include <iostream>
   #include <cstdio>
   
   using namespace std;
   
   inline int read() {
   	int x=0,s=1;
   	char ch=getchar();
   	while(ch<'0'||ch>'9') {if(ch=='-') s=-1;ch=getchar();}
   	while(ch>='0'&&ch<='9') {x=x*10+(ch^48);ch=getchar();}
   	return x*s;
   }
   
   int main() {
   #ifdef LOCAL
   	freopen("c.in","r",stdin);
   	//freopen("c.out","w",stdout);
   #endif
   	$0
   	return 0;
   }
   
   // by pycr
   

5. test code (Tab:test)

   #include <iostream>
   #include <cstdio>
   
   using namespace std;
   
   inline int read() {
   	int x=0,s=1;
   	char ch=getchar();
   	while(!isdigit(ch)) {if(ch=='-') s=-1;ch=getchar();}
   	while(isdigit(ch)) {x=x*10+(ch^48);ch=getchar();}
   	return x*s;
   }
   
   int main() {
   #ifdef LOCAL
   	freopen("c.in","r",stdin);
   #else
   	freopen("$1.in","r",stdin);
   	freopen("$2.out","w",stdout);
   #endif
   	$0
   	return 0;
   }
