Question

我在宏中有大量的查找和替换序列

:let@m=':%s/√/\\sqrt/g
:%s/∫/\\int/g
:%s/∑/\\sum/g
:%s/∏/\\prod/g
:%s/⋃/\\bigcup/g
:%s/⋂/\\bigcap/g
:%s/∪/\\cup/g
:%s/∩/\\cap/g
:%s/∂/\\partial/g
:%s/–/\--/g
:%s/—/\---/g
:%s/•/\\bullet/g
:%s/·/\\cdot/g
:%s/◦/\\circ/g
:%s/±/\\pm/g
:%s/∓/\\mp/g
<more stuff/>
'

如果这些查找和替换中的任何一个失败（例如，如果文件中没有 ∫），则后续的将不会运行。如何让 :%s///g 安静且无损地失败？

来自:help :s_flags：

[e]    When the search pattern fails, do not issue an error message and, in
       particular, continue in maps as if no error occurred.  This is most
       useful to prevent the "No match" error from breaking a mapping.

所以：

%s/√/\\sqrt/ge
%s/∫/\\int/ge
…
