问题描述
例如,我的 src.tex 是
For example, my src.tex is
SectionType *p = NULL;
我想把它改成
section_type *p = NULL;
我想要做的只是改变SectionType,但保持NULL不变,我使用了y/[AZ]/[az],但这将改变所有行.
what I want to do is just change the SectionType, but remains the NULL unchanged, I used y/[A-Z]/[a-z], but this will change all the line.
我的 sed 不支持 \L,\l,\U 和 \u 函数,它的版本是 3.* 并且在 FSF 下分发,而不是 GNU,可能是 GNU 可以很好地处理这些函数,但当时我可以不采用 GNU 的,因为我在 msys 中工作并且没有 GNU 包.
My sed do not support \L,\l,\U and \u functions, it version is 3.* and distributed under FSF, not GNU, may be GNU's works well with this functions, but at the time I could not adopt the GNU's because I'm working in msys and there is no GNU package.
有什么解决办法吗?

将 CamelCase 或 camelCase 转换为 camel_case:
Convert CamelCase or camelCase to camel_case:
sed -e 's/\([AZ][az]\)/_\l\1/g' -e 's/^_\([az]\)/\1/g' 文件.txt
输入:
SectionType *p = NULL;
sectionType *p = NULL;
ABCSectionType *p = NULL;
输出:
section_type *p = NULL;
section_type *p = NULL;
ABC_section_type *p = NULL;
