saveModule

saveModule(name,[moduleDir],[overwrite=false]))

Serialize a module (".dos" file) to a binary file with a file name extension of ".dom". It must be executed by a logged-in user.

The default value of moduleDir is the relative directory "modules" that needs to be created by the user. The system searches the relative directory "modules" in the following order: home directory of the node, the working directory of the node, and the directory with the DolphinDB executable. Please note that in the single node mode, these 3 directory are the same by default.

saveModule enhances the confidentiality and the security of the code.

name is a string indicating the name of the module.

moduleDir (optional) is a string indicating the directory where the module files are located.

overwrite (optional) is a Boolean value indicating whether to overwrite the existing module dom file.

Assuming the directory "modules" under the node's home directory contains the module files "ta.dos" and "system/log/fileLog.dos", the following example serializes the module files to binary files.

saveModule("ta");

saveModule("system::log::fileLog");
