@dr_ju_ju the G/M code at the beginning of the summary line is a link to the full entry.

@droftarts not for me it isn't.....

I don't know what has changed this morning, if anything, but I now see links to individual explanation pages from the GCode dictionary page (https://duet3d.dozuki.com/Wiki/Gcode#Section_G_commands), which at least gets me started in finding the info I need, but WHY are there no return links, to the dictionary page, on each of explanation pages ????

zapta

@droftarts, here is another example, searching the main gcode page for 'StealthChop' or 'Stealth' or 'Chop' brings nothing.

https://duet3d.dozuki.com/Wiki/Gcode

Searching that page for M569 doesn't help either since it has 8 entries which should be opened and searched individually, not to mention finding other commands that may mention 'stealthchop'.

I miss the old times.

I have noticed a fairly substantial change in my ability to use the GCODE page after this change.

As I try to help people in this forum, I search the GCODE page for things like:

current (Which Mxxx sets motor current.
idle (Which Mxxx sets the idle current)
endstop (how are endstops configured)
pullup (How are pullups configured for I/O pins)
leveling (which Mxxx are involved in bed/mesh leveling)

None of those get me where I have to be to help Duet users with their problems and I have to use duckduckgo.

Which potentially reduces my ability to help your customers solve their problems.

I wasn't opposed to the change in the beginning, but as I use the page more and more, I'm now feeling the issues of just having one-line summaries.

I like to help people, but when the burden gets too high, I ignore their problems and move on to something easier for me to do.

@alankilian I've half a mind of creating a "classic" GCodes library page which directly includes the individual entries, but I don't want to cause issues with the dozuki.

@droftarts if the gcode entries would be properly linked under "Gcodes/" rather than on the wiki root I could create a local copy every now and then for easy access. Since they do reside at the top level, this is more tedious since I'd need to parse the main GCodes page for links to get local copies.

@alankilian thanks for the feedback. We are looking at alternatives as I agree this change makes the gcode dictionary more difficult to use.

@oliof there is now an "individual gcodes" category. the Gn codes have been put in there. the M codes will follow soon.

@droftarts said in Gcode documentation change:

To maintain existing links (yes, they should all still work), the headings have to be shown in the new page, as they appeared in the old page, without a link in them. This lead to the layout with the link to the individual page and description on another line.

Nope, not universally true. There are MANY that are formatted like this one-

https://duet3d.dozuki.com/Wiki/Gcode#Section_M558_in_RepRapFirmware_Num_3

this one works, but not the above one

For what it's worth...

A script that puts a link at the top of the left hand menu, that if clicked, will re-assemble the single mega-page from all the separate pages.

It is written in a way that if included as a script tag in the wiki's root html template, it will only wake up on the correct page, and simply add a link to the menu. User can click it to assemble the mega page, or ignore it all together to leave it as-is. I'd recommend putting it in a file somewhere and referring to it so the browser can cache it so there's no download impact each page load.

For anyone that wants to run it themselves, just go to the gcode page, open JS console ( ctrl + shift + J for chrome, ctrl + shift + i for firefox ) , paste it in, press enter...

Works for me! (Using chrome/mac so had to open the console in a different way).

Can we have the official documentation page running this script automatically when opened? Loading time was very fast.

... also, is it possible to have links to this overall page? E.g. a link for G1 that will take you to the G1 in that page?

way above my pay grade to include it, but it is written in a way that has it do nothing if the user's not on the right page.

The page is inflated after loading, the browser doesn't know how to cope with sub-linking into a page that's altered after the main document as loaded, so some things are simply off the table.

That said, try the script I put here... https://forum.duet3d.com/topic/25459/mega-gcode-docco-page-gcode-file-navigator

...specifically the "cross linking" mentioned, and see if that's what you're after.

If the target section link is represented in the URL, the loader could potentially parse it after loading the parts and jump there, or something like that, but it's also above my pay grade.

See, then you went and made me feel bad

...script above is updated to reevaluate the hash link to re-bump into the correct location after the content injection.

It is also looking for "inflate content" in the URL query string, if it's there it will automatically inflate the content without needing to click.

@zapta said in Gcode documentation change:

I updated and tested the script in greasemonkey (firefox) / tampermonkey (chrome) plugins... so if you want it to work automagically, that's one way to do it without the wiki admins applying the script.

With the plugin, this link will automatically make the large page without needing to click:
https://duet3d.dozuki.com/Wiki/Gcode?inflateContent

And if the 'inflateContent' link is too much of a hassle, you can always have it build the page by changing the last part in the script from ...

// auto-trigger...

if (qstring === 'inflateContent') {
    processMegaPage();
}

...to...

processMegaPage();

@thekm Your script works beautifully and I wanted you to know how much your work is appreciated.
My workflow will probably be to run this whenever the dictionary is updated, and save the page locally for regular reference, since it's hammering the site for 45 seconds straight to load all of the content...
The crosslinking and gcode browser features are really great too, thanks for that. This is what the gcode dictionary should be.
