Runtime Library: OS Command Wrapping
This library has 122 classes.
ECF: os-command.ecf
Source code: directory list
Classes for creating cross platform wrappers of OS commands with about 30 "out of the box" commands provided.
General Features
- Command templates are based on the powerful Evolicity text substitution library.
- Support for command output capture, and error output capture.
- Automatic escaping of path arguments conforming to EL_PATH, namely EL_FILE_PATH and EL_DIR_PATH. All Windows paths are automatically put in quotes. Unix paths are automatically escaped with \ for reserved characters. This has some advantages over putting them in quotes.
- Designed for cross platform use, with special features for post-capture processing of output lines so they are consistent across platforms. See classes EL_FIND_DIRECTORIES_COMMAND_I and EL_FIND_FILES_COMMAND_I as an example. Here the Unix find command and the Windows dir command are made to appear exactly the same for specific tasks.
- Support for making "convenience wrappers" without any need to create a new class. These are classes: EL_OS_COMMAND and EL_CAPTURED_OS_COMMAND.
- Has factory class EL_OS_ROUTINES_IMP (accessible via EL_MODULE_OS) which contains factory functions for common OS system commands.
Information Commands
These are "out of the box" command for obtaining system information.
- Unix command to parse output of nm-tool to get MAC address of ethernet devices
- Unix command to obtain CPU name
