3 months ago Comparison of Understand and VS Code over other VS Code extensions:
Pros:
- Many languages are available with the same features.
- Understand: The C-like languages and others for a total of 13 languages
- Microsoft C/C++: Only the C-like languages
- The analysis errors and warnings are saved.
- Understand: Errors and warnings are there when opening the project.
- Microsoft C/C++: Must analyze all files each time the project is opened for errors/warnings (unless there's some setting I'm missing.)
- Much more information is available on hover.
- Header file paths:
<stdio.h>to seeC:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\ucrt\stdio.h - Arguments of K&R function:
void regerror(char *s) - CodeCheck detailed descriptions, usually with elaboration, examples, and other sources to read
- Header file paths:
- So many more customizable warnings (CodeChecks) are available.
- Understand: 3000+ checks, 99% MISRA rules coverage, 90% AUTOSAR rules coverage, Clang-Tidy and Clang warnings
- Microsoft C/C++: Clang-Tidy and chosen compiler warnings
- The startup time is fast.
- Understand: 17ms
- Microsoft C/C++: 51ms
- The analysis status is clear and thus feels responsive.
- Understand: "Analyzing 9 files 50%"
- Microsoft C/C++: "Parsing workspace"
- See even more information in Understand.
- Understand: Find out the underlying types of variables, view the control flow graph, organize an architecture, calculate metrics, etc.
- Microsoft C/C++: (No companion program)
- Faster analysis
- Understand: Full analysis of Apache without errors: 0:06
- Microsoft C/C++: Partial analysis of Apache with errors: 1:17
Cons:
- Not free
- Understand: paid
- Microsoft C/C++: free
- See issues
Robby, I would like to have a comparison write-up for VSCode against at least one other option. You verbally compared it to Microsoft's C/C++ plugin (I think that's the one it was) and I would like to have that as a written out comparison so we can use it on marketing materials, maybe the marketplace, front web page, support site, etc. If there are other VSCode tools or plugins to compare it to, that would be great as well to add more.
On the scitools.com home page we have a section about the plugin and I want to make sure that the paragraph is highlighting features that can't/aren't being done in VSCode that are more unique to Understand. If you have any suggestions for this that would be great (and this may easily come from the comparison request above).
