cabal-add

Extend Cabal build-depends from the command line.

cabal-add does not have limitations of cabal-edit: it works on any sectioned Cabal file, supports stanzas and conditional blocks, and preserves original formatting.

Install the executable with

cabal install cabal-add

To add a dependency on foo, switch to a folder with your project and execute

cabal-add foo

If you are using Cabal 3.12+ which supports external commands, you can omit the dash:

cabal add foo

Command-line arguments:

• --project-file FILE

  Set the path of the cabal.project file. Detect cabal.project or *.cabal in the current folder, if omitted.

• ARGS

  Optional target (wildcards such as exe, test or bench are supported) to update, followed by a non-empty list of package(s) to add to build-depends section. Version bounds can be provided as well, use quotes to escape comparisons from your shell. E. g., 'foo < 0.2'.
