bash - Sharing header file between a C program and a shell script -

-

How do I share a C header file with a shell script?

Communicates with C program through pipelines called shell script. Suppose that enum SAMPLE_ONE, which is defined in the C header file, pipe written by the C program. Shell script reads the value of enum from the pipe. What is a way to share the header file between the C programs and shell scripts - in such a way that I only need to update the header file once and do not have to write the same header string in the shell script?

See the following example: 

  $ cat foo.h #define ENUM enum #define COMMA, ENUM foo_t {FOO_VALUE1 = 11 COMMA FOO_VALUE2 = 22 COMMA FOO_VALUE3 = 33}; Include $ cat foo.c # & lt; Stdio.h & gt; #include "foo.h" # print_enum (x) printf ("% s =% d \ n", #x, x) int main () {enum foo_t foo = FOO_VALUE1; Print_enum (FOO_VALUE1); Print_enum (FOO_VALUE2); Print_enum (FOO_VALUE3); Return 0; } $ Cat foo.sh #! / Bin / bash shopt -s extension_allies alias ENUM = 'true' alias COMMA = source foo.h enum_names = ($ {! FOO_ *}) for name in $ {enum_names [@]}; Do echo $ name = $ {! Name} done $ gcc foo.c $ ./a.out FOO_VALUE1 = 11 FOO_VALUE2 = 22 FOO_VALUE3 = 33 $ bash foo.sh FOO_VALUE1 = 11 FOO_VALUE2 = 22 FOO_VALUE3 = 33 $

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
