在以太坊编程中,往往需要压缩json文件,这时候就需要剔除json里多余的空格的和换行符,效果如下:

图(1) json文件去掉空格后,再压缩为一行

    用nodepad++打开该*.json文件,然后使用如下步骤:

1、用notepad++替换所有的行首空格

    按CTRL+H 选择正则表达式-- 查找目标:^\s+ 替换为空,如图(2)所示:

2、用nodepad++替换所有的换行符

    按CTRL+H 选择正则表达式-- 查找目标:\r\n 替换为空,如图(3)所示:

dff2b475 Adds pre-multiplication overflow detection to catch cases where dimension products would exceed size_t max. The previous check only detected when overflow resulted in exactly 0 or SIZE_MAX, missing other cases. Retains the original post-multiplication check for backward compatibility. Adds tests verifying overflow detection with dimensions (2^32+1)×(2^32), which previously overflowed silently to 2^32. This prevents custom SAX handlers from receiving incorrect array sizes that could lead to buffer overflows. Signed-off-by: Ville Vesilehto <ville@vesilehto.fi> 16 小时前
