Are there SKILL functions to modify cds.lib?

MorrisDH

I am using shell commands to modify cds.lib because I've not found a skill command that will do this.

Add a library

shell("echo DEFINE myLib /path/to/myLib >> cds.lib")

ddUpdateLibList()

Delete a library

shell("cat cds.lib | grep -v myLib >> xx ; mv xx cds.lib")

ddUpdateLibList

Is there a SKILL funtion that will add or remove libraries from cds.lib?

  • Hi Morris,

    I did such thing long time ago, but i forgot where i put it, so a have re-did it for you.

    See below the function lib2 comment that use sed (stream editor ) as Aurel suggested. Although one can imagine a pure skill function that read cds.lib parse it and change the library pattern. I show you also an example if you use relative path to a global variable $PRJ_DIR for instance.

    There is an example with "grep -q " that checks if the string is allready in the cds.lib to put it in. Although, if you want to create a library, within cadence, you need to use the skill function dbCreateLib.

    _______________

    ;ddSetForcedLib("");=> Forece reference cds.lib to be ./cds.lib if not

defun(lib2comment (@optional (toinclude "DEFINE libA ./path/libA") (AA "")(BB "#") (cdslib "./cds.lib") (verb nil))
let((cmd fp)
cmd=strcat("cat " cdslib " |sed -e " "\"s,^" AA toinclude "," BB toinclude ",\" > ./tmp; mv ./tmp " cdslib)
fp=outfile("./toScript.sh") fprintf(fp "%s" cmd) close(fp)
when(verb  sh("cat ./toScript.sh"))
sh("./toScript.sh ")
))

lib2comment("DEFINE libB ./path/libB" "" "#"); => pattern does not exist => nothing commented
lib2comment("DEFINE libA ./path/libA" "" "#"); => comment
lib2comment("DEFINE libA ./path/libA" "#" ""); => uncomment
lib2comment("INCLUDE \\$PRJ_DIR/project.lib" "#" "")
lib2comment("INCLUDE \\$PRJ_DIR/project.lib" "" "#")
sh("cat ./cds.lib")

;(setq cdslib "./cds.lib")

defun(lib2add (@optional (toinclude "DEFINE libA ./path/libA") (cdslib "./cds.lib") (verb nil))
let((cmd fp)
cmd=strcat("if (! grep -q \"" toinclude "\" " cdslib "); then echo APPEND in cds.lib; echo " toinclude " >> "  cdslib "; else echo ALLREADY in cds.lib;fi ")
fp=outfile("./toScript.sh") fprintf(fp "%s" cmd) close(fp)
when(verb sh("cat ./toScript.sh"))
sh("./toScript.sh")
))

lib2add("DEFINE libB ./path/libB" "./cds.lib" t);=> nil
sh("cat ./cds.lib")
lib2comment("DEFINE libB ./path/libB" "" "#")

    Hi ebecheto, Your solution is far more flexible than what I need. For my usage the library name and location will be the same always.  I will run your example out of curiosity and to see the generated sed command but my final solution will definitely be much simpler.

    Thanks,
