Installation step missing?

[Nielius]

I wanted to try this cool project out, but it looks like a step in the installation process is missing: it looks like you need to compile the fennel files. Is that right?

What I did

I didn't have luarocks or fennel installed, so I did this:

brew install luarocks
luarocks install fennel

git clone https://github.com/agzam/spacehammer ~/.hammerspoon

Then I reloaded the hammerspoon config with the button in the top-right. (Note I didn't reboot.)

Expected result

Cool spacehammer keybindings.

Actual result

What resolved it for me

I added this makefile:

SOURCES := $(shell find ./ -type f -name '*.fnl')

TARGETS := $(patsubst %.fnl, %.lua, $(SOURCES))

all: $(TARGETS)

%.lua: %.fnl
	fennel --compile $< > $@

and ran make all.
(One file actually filed to compile, but that didn't seem to matter.)

P.S.

Awesome project! I look forward to exploring it more.

Thanks for reporting this.

If you install luarocks and fennel, you should not need to compile the fennel into lua. You will need to reboot as our init.lua changes the load paths to support fennel on startup but doesn't change that on future reloads.

I'm not sure if this is the same issue, but I:

• Updated to the latest hammerspoon
• ran brew install luarocks
• ran luarocks install fennel
• ran git clone https://github.com/agzam/spacehammer ~/.hammerspoon

And I get this error whenever I reload the config:

Spacehammer was working ok prior to me updating hammerspoon

[jaidetree]

@tntmarket Can you please create a separate ticket for this? I just saw a new Hammerspoon was dropped and it's good to track these issues separately. Thanks! In the future, please report an issue like this as a separate issue. Thank you!

For others running into this issue, next fixed it for me:

-- ...
package.path = package.path .. ";" .. "/usr/local/share/lua/5.3/?.lua"
fennel = require("fennel")
-- ...

[PaulMorris]

I did the same steps as @tntmarket and got the same error. Thanks @larryskye , adding that line to init.lua fixed it for me.

[frenchy64]

I managed to fix this by upgrading to lua 5.4 via these steps, except I changed the last step install fennel to

luarocks install --local fennel

as otherwise it would not install fennel to ~/.luarocks.

[yqrashawn]

For me reinstall a latest hammerspoon fix the problem

[Grazfather]

The issue seems to be that fennel was not installed into the same version of Lua that Hammerspoon is using. Make sure to use the correct one and the issue should go away.
