emacs-w3m help topics missing until accessing them via GUI help

[dylangleason]

Summary

After a fresh installation of scel, most help topics appear to be missing when using w3m. Running sc-index-help-topics interactively does not appear to resolve the issue, but viewing the same help topics in the GUI does cause those help topics to subsequently appear using w3m after restarting the interpreter.

Configuration

• OS: Linux 4.19.0-8-rt-amd64 #1 SMP PREEMPT RT Debian 4.19.98-1 (2020-01-26) GNU/Linux
• SuperCollider version: 3.10.0 (from the Debian repositories)
• scel branch: master
• Emacs: 27.0.91 (using helm and helm-flx)

SuperCollider Help paths

("/usr/local/share/SuperCollider/Help" "~/.local/share/SuperCollider/Help")

Note that I installed Supercollider via the Debian repositories, but not supercollider-emacs, since I am using an Emacs compiled from source. Not sure if this is related to the issues I am experiencing or no. Inspecting /usr/share/SuperCollider does reveal a HelpSource directory; I am guessing this is where the doc index is generated from and stored as HTML ~/.local/share/SuperCollider/Help...

Steps to Reproduce

1. Ensure sclang interpreter started: sclang-start
2. C-c C-h to search for "Pbind"
3. No help topic appears in helm buffer with: [No Match]
4. C-c h to search for "Pbind"
5. Help topic appears in helm buffer and hitting enter brings up GUI window with correct help topic.
6. Repeat step 2.
7. "Pbind" now appears in helm buffer, but pressing enter results in "SCLang: no help for Pbind"
8. Try refreshing index sc-index-help-topics, and repeat step 2: no change.
9. Shutdown sclang interpreter with sclang-stop
10. Repeat step 1-2: "Pbind" shows up in helm buffer and hitting enter brings up w3m buffer with correct help topic.

It seems that gui compiles files into "~/.local/share/SuperCollider/Help" so after reindexing they appear in sclang-help-topic-alist.

Having this issue too. reindexing help, but not so much. It looks like Supercollider is compiling the helpfiles into html on-demand. Meaning that the helpfiles aren't compiled to HTML until you access them via de GUI. (on MACOS)

Solved https://github.com/supercollider/supercollider/issues/5489 Run SCDoc.renderAll on the SClang server. Then sc-index-help-topics. Now you got all your help files.

Verified working with SCDoc.renderAll. Closing.
