COBOL#

Environment Variables#

To configure the COBOL provider you can use the following environment variables:

  • NIXPACKS_COBOL_COMPILE_ARGS: Provide custom cobc arguments
  • NIXPACKS_COBOL_APP_NAME: Provide the name the cobol file to compile

Setup#

The COBOL provider uses GnuCOBOL

Install#

GnuCOBOL and gcc are installed

Build#

the following command is used ( see section below to see how the arguments are generated ): cobc <cobcArgs> ./<appName> <path>

cobcArgs#

  • If NIXPACKS_COBOL_COMPILE_ARGS is set that is used`
  • Otherwise -x -o is used

appName#

  • First if NIXPACKS_COBOL_APP_NAME is set that is used.
  • next the source files are searched for the presence of an index.cbl. If one is found index is used
  • Lastly the source files are searched for any file with the cbl extension. If one is found the file name is used.

path#

  • The source files are searched for *<appName>.cbl if found that path is used.

Start#

./app-name is run

Caching#

GnuCOBOL and gcc are cached between builds
