$ escape sequence at build_rule.txt

$ escape sequence at build_rule.txt

[peter.kirmeier]

Hi all,

I tried to add a AWK replacement into the build_rules to become part of the generated makefiles:

    <Command>
        "$(TOOLS_DIR)\gawk.exe" "NF{gsub(/ *\\$$/,\"\"); print}" infile.in > outfile.out

Unfortunately I don't get it, how the dollar sign can be escaped to the doubled $$ which is used by make for placing a single $ at the command.

Can someone help?

Thanks,
  Peter

Peter,

Do you think the build_rules.txt parse is removing one of the $? I'm not sure if this will work but what happens if you use 4 $? 

What do you see in the generated makefile?

Re: $ escape sequence at build_rule.txt

[Peter Kirmeier]

Hi Andrew,

the line I wrote first..
    "$(TOOLS_DIR)\gawk.exe" "NF{gsub(/ *\\$$/,\"\"); print}" infile.in >
outfile.out
.. failed with this error message..
    makefile(527) : fatal error U1001: Syntaxfehler: ung³ltiges Zeichen "/"
in Makro 
       (means syntax error due to invalid character "/" in macro)
..and brought this result at the makefile:
    "$(TOOLS_DIR)\gawk.exe" "NF{gsub(/ *\\$/,\"\"); print}" infile.in >
outfile.out

Also with this line..
    "$(TOOLS_DIR)\gawk.exe" "NF{gsub(/ *\\$$$$/,\"\"); print}" infile.in >
outfile.out
.. I get exactly the same error and output (multiple dollars are stripped
down to a single one)

Tried to get some more details of how the macros work by looking at python
scripts.
All I see is that only fixed macros are supported like ${s_base} or
$(OUTPUT_DIR).
I couldn't find a way to actually espace the $(xx) sequence at all.

Here are some more tries to figure out how the $ is processed:

$() fails because no macro name is set but prints $() into the makefile,
$($) fails because second $ is unknown and prints $($) into the makefile,
${} fails because { is no valid character but prints ${} into the makefile,
$ or $$ or $$$ or $$$$ .. fails because next character "/" invalid and
prints a single $ into the makefile.

It seems there is one exception that multiple $ signs will not be printed
1:1 into the makefile. 
All other tries were printed correctly into the makefile.
So if $$ would be printed 1:1, too, it should work as I expected.
Unfortunately I don't get $$ with anyone of them.

Guess there is no support for any escape sequence yet, right?
Any idea to get this working and/or in case $$ should work in
build_rules.txt, would you plan to fix this?

Best Regards,
  Peter Kirmeier

PS: Maybe a quick and simple solution could be to add a predefined $(DOLLAR)
marco or anything like that into the python scripts?

Peter,

You can also looks at the makefile (GNUmakefile) produced by the build as they will live in the Build/ output directories.

Sorry I was just taking a guess. It looks like an issue in how the file is parsed hopefully the maintainer can chime in with more details. 

Short term can you make it work if you pass the pattern in via a file (awk -f)? You should be able to use the existing macros to point to a file checked into your source tree.

Re: $ escape sequence at build_rule.txt

[peter.kirmeier]

Hi Andrew,

in the meantime I will work around this issue by using a script file as AWK input, so the command is not part of build_rules.txt.
Thanks for your help.

Dear Yonghong, Liming,

first I thought that my issue came by myself (not knowing how to escape the dollar sign at build_rules.txt).
But now I think this is a real issue of the build tools and that build_rules.txt doesn't have the capability of escaping the $ sign.
Therefore I hope that you could fix the tools accordingly.
For example, by adding an "escape sequence" for the $ sign (or at least by adding a predefined macro like "$(DOLLAR)" which expands to "$").

Thanks,
  Peter

Re: $ escape sequence at build_rule.txt

I filed a bug report and assigned it to you initially.
Hopefully I did it right because BugZilla was a pain to me in entering this issue :)

Best Regards,
  Peter
