README allows localhost but fonts missing and setting offline with undocumented edit

[CoolGames]

"Error: Failed to Load Font:" when using TEXT on Ubuntu Studio localhost. next issue is error blocscad.js needs to be set offline true as revealed by phone call to developer Blockscad.offline = true; // true unless using a cloud service backend for file management

You need to run a local webserver to be able to load fonts. I usually use either a python webserver

python -m SimpleHTTPServer 9000

or the (faster!) node.js server

http-server -p 9000

then access the page at localhost:9000.

Does this fix your font loading issue?

I am running full Apache2

That's what we're using in production, a bog-standard Apache install. On Apr 28, 2016 9:59 AM, "Lee T. Davy" notifications@github.com wrote:

I am using both Ubuntu Studio and Beagle Bone Black with machinekit (LinuxCNC / EMC2) and neither is able to find the fonts in the subdirectory on BlocksCAD/fonts Is there packages required for truetype on Linux ?

Also uploaded to my GoDaddy domain in subdirectory using git clone and it also has the error

I'll try to check this against a fresh Ubuntu image tonight to figure out what dependencies are actually required. If memory serves, we're hosting on Ubuntu, but it could be centos. On Apr 28, 2016 10:16 AM, "Lee T. Davy" notifications@github.com wrote:

silly things to check:

1. are the font files actually in your filesystem?
2. if you run a node.js webserver, is it able to load the fonts?

[CoolGames]

Not sure how to run node.js webserver separately ? Fonts can be found in filesystem in BlocksCAD subdirectory and only ones offered !

Here is what I save from on line to localhost to get the error

//!OpenSCAD

translate([-50, 0, 10]){ color([0.2,0.8,1]) { linear_extrude( height=2, twist=0, center=false){ text("Cool Games", font = "Roboto", size = 20); }

} }

Save as OpenSCAD (can't attach)

if you have node.js installed, try this:

navigate to the top level directory of blockscad (it should contain index.html) http-server -p 9000

if you don't have node.js, but you have python, from that same directory you can instead run python -m SimpleHTTPServer 9000

then from your web browser, access BlocksCAD from http://localhost:9000

[CoolGames]

Python worked so what is difference from apache running the code ? Is there a need to reconfigure on localhost and GoDaddy ?

[yoderjen]

No idea. Hopefully Matt will have some ideas. If you manage to fix it, let me know what needed to happen so I can help others in the future.

I have nodejs 4.2.6 installed including dependencies with synaptic

leetdavy@leetdavy-StudioAir:/var/www/html/BlocksCAD$ dpkg -l | grep node
ii  nodejs                                        4.2.6~dfsg-1ubuntu4                                 amd64        evented I/O for V8 javascript

Closing this because I think it was not a BlocksCAD issue.
