JShell如何（或在哪个文件中）存储其配置设置？

Question

The doc says:

Remember that the startup scripts are loaded into the current session only when the state is reset. The contents of the script is stored, not a reference to the script.

( https://docs.oracle.com/javase/9/jshell/scripts.htm#JSHEL-GUID-AC2A6582-6A9A-48B1-ABBF-4C9536CDFD07 )

For example,

/set start -retain mystartscript.jsh

But where does it store the contents of mystartscript.jsh ?

Answer 1

Using a relative filename like you do in your example:

/set start -retain mystartscript.jsh

JShell would look for mystartscript.jsh in [ user.home ]/ mystartscript.jsh

You could also give it an absolute file path:

/set start -retain /my_custom_jshell_scripts/mystartscript.jsh

Robert Field—the JShell lead architect—explains in this tutorial how to ( re )set/unset JShell's built-in DEFAULT startup scripts plus custom .jsh startup scripts.
