A JavaScript compression tool written last year, used for js compression on x2blog.cn. However, it has not been released to the public. Now I use it to fill up the number of articles. It is not good to not update the blog. Haha

Overview:
X2JavascriptCompactor can package multiple Javascript script files into one file and delete the original Comments, whitespace, and newlines in files. Not only can it effectively reduce network transmission volume, but it also makes script files difficult to analyze and crack. The software supports simultaneous packaging of multiple files at the same time, that is, multiple output files can be created. Each output file corresponds to a certain input file, and the input files corresponding to each output file are independent of each other.

Note:
I have been unable to find a suitable JS packaging tool on the Internet. The compressed files often cannot be executed, so I wrote this tool myself. The development is based on the .net 1.1 framework, so it is necessary to For correct execution, .net framework must be installed, which can be downloaded for free from the Microsoft website: http://download.microsoft.com/download/7/b/9/7b90644d-1af0-42b9-b76d-a2770319a568/dotnetfx.exe. At the same time, for the sake of development efficiency, the system does not conduct detailed syntax analysis of Javascript. Therefore, in order to ensure that the compressed Javascript file can be executed correctly, it must comply with the following conventions:
1. The original file can be executed correctly;
2. It is not necessary to add a semicolon at the end of the structure: that is, var f=function(){}, var a={p1:1,p2:2} does not need a semicolon at the end of the statement, of course it can be added;
3. There must be a semicolon at the end of an ordinary statement: such as var a=1; alert(a); There must be a semicolon at the end of an ordinary statement.
I believe that even without this convention, everyone would still write Javascript according to this syntax. The explanation here is just to emphasize that after all, the Javascript specification does not mandate a semicolon ending.

Usage process:
1. Create or open a project with the suffix *.jcp;
2. Create an output file, where the compressed file content is saved. You can select an existing file , or create a new file;
3. Select an output file and select the corresponding input file for this file, which will be displayed in the list on the left;
4. Adjust the order of the input files so that it meets the execution order requirements , can be executed through the up and down arrows;
5. Click the Start Compression button, the software will automatically analyze the input file, compress and package it into the output file;
6. You can decide whether to save the project file according to your needs.
