how can I display all function name from cscope database?
cscope
Solution
Try the following:
cscope -R -L -2 ".*" | awk -F ' ' '{print $2 "#" $1}' | sort | uniq
- The command `cscope -R -L -2 ".*"` will output functions called by any function (see explanation of the options below). For each reference found, `cscope` outputs a line consisting of the file name, function name, line number, and line text, separated by spaces.
- Use `awk` to extract the function name `$2` and file name `$1` separated by `#`. Change `$2`, `$1` and the separator `#` if you need other output fields or separator.
- Sort the output with `sort`.
- Get unique items with `uniq`.
`cscope` options (see http://cscope.sourceforge.net/cscope_man_page.html):
`-R` Recurse subdirectories for source files.
`-L` Do a single search with line-oriented output when used with the -num pattern option.
`-2 ".*"` Go to input field num (here 0-based field 2) and find pattern (here `.*` for all). You can see the input fields in cscope's screen mode. This may vary depending on the version you are using. The fields for version 15.8a under debian are:
- 0: Find this C symbol:
- 1: Find this global definition:
- 2: Find functions called by this function:
- 3: Find functions calling this function:
- 4: Find this text string:
- 5: Change this text string:
- 6: Find this egrep pattern:
- 7: Find this file:
- 8: Find files #including this file:
Problem
I am trying to find a way to dump ALL the functions name and it's path from cscope database. Is there a way to do that from cscope CLI? Note: the cscope source code is available for download.
