kandi X-RAY | perforator Summary
perforator is a Go library typically used in Performance Management, Monitoring applications. perforator has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.
Perforator is a tool for recording performance metrics over subregions of a program (e.g., functions) using the Linux "perf" interface. The perf tool provided by the Linux kernel only supports collecting statistics over the complete lifetime of a program, which is often inconvenient when a program includes setup and cleanup that should not be profiled along with the benchmark. Perforator is not as comprehensive as perf but it allows you to collect statistics for individual functions or address ranges. Perforator only supports Linux AMD64. The target ELF binary may be generated from any language. For function lookup, make sure the binary is not stripped (it must contain a symbol table), and for additional information (source code regions, inlined function lookup), the binary must include DWARF information. Perforator supports position-independent binaries. Perforator is primarily intended to be used as a CLI tool, but includes a library for more general user-code tracing called utrace, a library for reading ELF/DWARF information from executables, and a library for tracing perf events in processes.

QUESTION
Extract list items from a string
Asked 2021-Mar-02 at 22:49
I have a line like
"In this task, you need to use the following equipment:
- Perforator
- Screwdriver
- Drill
After finishing work, the tool must be cleaned."
How do I extract elements from this string? As a result, I need an array like {"Perforator", "Screwdriver", "Drill"}
...ANSWER
Answered 2021-Mar-02 at 22:39One possible way to do it would be to break the string into lines, then try to convert each line into a number plus text, and take only the lines where the conversion is successful.
