CH简单使用及技巧

NOTE: Please remove existing Ch and its toolkits/packages first, if you have. Ch Standard Edition and Professional Evaluation cannot be both installed to the same machine.

Tips for Using Ch

• If it is the first time to run Ch. run ch -d<br>to create a Ch startup configuration file in your home directory. To get started, type help at the Ch shell prompt.

  If you don't want to use Ch in a command shell, please try Ch (Integrated Development Environment) from SoftIntegration partners. Ch IDE allows you to edit and execute C/Ch/C++ programs, and display the output within the same Graphical User Interface.

• In the Ch shell, you can simply type the C/Ch file name to run your program (you need to run "chmod +x file_name.c" first in Unix, Mac) If you have multiple files for a program, click to see how to run the program without Makefile:
• Ch supports . Unix commands such as awk and sed can be used inside Ch scripts as in Perl, Bash, or csh. Ch built-in string type string_t and foreach-loop are especially useful for shell programming. Below is an example: string_t token, str="dir1 dir2 dir3";<br> foreach(token; str) {<br> mkdir $token<br> }<br>
• Ch supports such as opendir() and readdir() for cross platform directory and file handling.
• A better calculator for quick calculations, easy to check if there is typo for the input number. For example: C:/&gt; 23+344+23.02+343<br> 733.0200<br> C:/&gt; 733.02/4<br> 183.2550<br> C:/&gt;<br>
• Like in Unix, a command in Windows can be executed in the background by appending "&" at the end of the command. For example,
  c:/&gt; notepad &amp;<br>
• To turn on debug for running CGI in Ch, add "-g" flag, the first line for your Ch CGI script file will become
  #!/bin/ch -g <br>
• Ch demos contain code for C90, C99, C++ and other features. Click for more.
• Numerical computing and 2D/3D graphical plotting functions are available in .

• Web-based graphical plotting, numerical analysis, mechanism design and analysis, and control system design and analysis can be found
• There are two ways to build functions used by Ch.
  1. To build functions used in Ch shell, you can put your function files in a directory and set your _fpath to include this directory. You can check sample ~/.chrc file which can get by running ch -d<br>
  2. To call your functions in static/dynamic libraries, check our
• To access Ch file functions or variables from Ch shell command line, please visit .
  and .
• To embed Ch into your applications as a script engine, check our
• We provide cross platform . It can be compiled by your desired compiler. These graphical library functions have the same APIs in Ch Professional Edition. They also can run in Ch Professional Edition without compilation.
• For statistic analaysis, please check our .
• If you are an experienced C/C++ user, you may only need to read Appendices B and C in Ch User's Guide with comparison to C and C++, plus Chapters 23 and 24 for 2D/3D plotting and numerical analysis available in Ch Professional Edition. Chapters 1, 2, 3, and 4 will be useful to getting started to use Unix shell.
