tldr hangs indefinitely

[sebnyberg]

I'm using Doom Emacs

GNU Emacs     v27.1
Doom core     v3.0.0-pre
Doom modules  v22.09.0-pre

I installed tldr using the regular procedure (package! tldr).

Running M-x tldr-update-docs works just fine.

Running M-x tldr makes Emacs hang indefinitely.

Since I know nearly nothing about Emacs, Doom Emacs or Lisp, I turned to opensnoop and strace -f for clues and found these two syscalls:

renameat2(AT_FDCWD, "/home/seb/.emacs.d/.local/cachetldr-main", AT_FDCWD, "/home/seb/.emacs.d/.local/cache/tldr/", RENAME_NOREPLACE) = -1 ENOENT (No such file or directory)
newfstatat(AT_FDCWD, "/home/seb/.emacs.d/.local/cache/tldr/", 0x7ffe2d6596d0, 0) = -1 ENOENT (No such file or directory)

It appears that the source path is missing a /, i.e. cachetldr-main should be cache/tldr-main.

As a temporary fix, you can symlink the directory

ln -s ~/.emacs.d/.local/cache/tldr-main ~/.emacs.d/.local/cache/tldr
