System: Ubuntu 22.04.4 LTS running on WSL on Windows 10 with a successful build of Gramps 5.2.0 from source. However, this is the first time I’m building addons (gramps52 branch) and running into an error with the ‘init’ command to make.py: ```python ~/dev/addons-source$ GRAMPSPATH=/home/codefarmer/dev/gramps LANGUAGE='en_US.UTF-8' python3 make.py gramps52 init AllNamesQuickview make.py: LANGUAGE is en_US.UTF-8... good! Traceback (most recent call last): File "/home/codefarmer/dev/addons-source/make.py", line 214, in from gramps.gen.plug import make_environment, PTYPE_STR ModuleNotFoundError: No module named 'gramps' ``` The error is on [L214 of make.py](https://github.com/gramps-project/addons-source/blob/5eafdf9d85167c28480655bc9d261e7634ec544b/make.py#L214) which is accessing Gramps modules. I’ve set GRAMPSPATH to point to the root of the gramps source folder. What am I overlooking? BTW, I get the same error in the MSYS development environment. ---

This looks like a bug. I’ll investigate. I only tend to use the _build_ and _listing_ options myself, but _init_, _update_ and _compile_ are also important. ---

Thanks for your time on this, @Nick-Hall . Because it’s the first time I’m building addons I am not sure which of the available make commands are to be used, and in what order. I was simply going by intuition that `init` has to be the first step. `Build` command works without errors, although `listing` command fails and I wonder if it is because things aren’t initialized properly? ```python ~/dev/addons-source$ GRAMPSPATH=/home/codefarmer/dev/gramps LANGUAGE='en_US.UTF-8' python3 make.py gramps52 listing AllNamesQuickview make.py: LANGUAGE is en_US.UTF-8... good! Building listing for 'lt'... Traceback (most recent call last): File "/home/codefarmer/dev/addons-source/make.py", line 864, in fp_out = open(r("../addons/%(gramps_version)s/listings/") + FileNotFoundError: [Errno 2] No such file or directory: '../addons/gramps52/listings/addons-lt.json' ``` ---

OK, ignore the error on `listing` command - just needed to create the “listings” directory manually, i.e. `../addons/gramps52/listings`. ---

Actually, I think that there is a problem with the _listing_ option when a single addon is specified. There is also some tidying up required - black formatting and removing duplicate and redundant code. ---

I’ve fixed the _init_ command. There wasn’t a problem with the _listing_ command. The workflow for translations is to first run _init_ to create the `pot` file: ```sh python make.py gramps52 init MyAddon ``` Then run _init_ again with a language to create the corresponding `po` file: ```sh python make.py gramps52 init MyAddon fr ``` Finally the `po` files can be compiled into `mo` files using: ```sh python make.py gramps52 compile MyAddon ``` When changes are made to an addon, we run _build_ to create the `tgz` file: ```sh python make.py gramps52 build MyAddon ``` and then the listings can be updated using: ```sh python make.py gramps52 listing all ``` Set your `GRAMPSPATH` environment variable to point to your Gramps source code. I’ve never used any of the other commands myself. The _as-needed_ looks useful. I’ll look at creating some functions to remove some of the duplicate code. ---

Thanks, @Nick-Hall . Your change resolved the error, and the workflow description is very helpful. ---
