Hi, is there an easy way to get a list of all features that a font has and typeset a sample text to see the result of every single feature? There probably is, but I couldn't find anything... All best Thomas

You'll get only the features with otfinfo in the terminal. For example: iMac:~ voss$ otfinfo -f `kpsewhich LibertinusSerif-Regular.otf` c2sc Small Capitals From Capitals calt Contextual Alternates case Case-Sensitive Forms ccmp Glyph Composition/Decomposition cpsp Capital Spacing dlig Discretionary Ligatures frac Fractions hlig Historical Ligatures kern Kerning liga Standard Ligatures lnum Lining Figures mark Mark Positioning mkmk Mark to Mark Positioning onum Oldstyle Figures pnum Proportional Figures salt Stylistic Alternates smcp Small Capitals ss01 Stylistic Set 1 ss02 Stylistic Set 2 ss03 Stylistic Set 3 ss04 Stylistic Set 4 ss05 Stylistic Set 5 ss06 Stylistic Set 6 ss07 Stylistic Set 7 subs Subscript sups Superscript tnum Tabular Figures zero Slashed Zero Herbert

Thank you, I was aware of that. But that's only the first step: you still have to use this list to define ConTeXt featuresets and then typeset. I was trying to build a cld document that automates this process, but can't get it to work. And I suspect that somewhere in the distribution, there is already a module that does exactly that. Thomas

You get a lot of information with mtxrun --script fonts --info <fontname> but no samples. You can also get font information via mtxrun --script server --start and then open the given address in your browser; AFAIR you get samples, but it doesn’t work for me ATM, because the server script is not found in the current directory (might be a misconfiguration on my side).

If you cd to .../tex/texmf-context/scripts/context/lua, start mtxrun --script server --start then open http://localhost:8088/mtx-server-ctx-fonttest.lua You should be able to check font samples with different features enabled. But I get another 404 on /mtx-server-ctx-fonttest-temp-02.pdf If it works for you, then it’s a problem of my installation, otherwise a regression in current LMTX... Hraban

No, I get the same error message, this looks promising but doesn't work. And at the risk of sounding grumpy, but all of this is too much manual intervention; I would like to have a completely automated script. So I'll show what I have and add a few comments: local Feature_Table = { } local Parsed_Features = { } local My_Font = environment.arguments["font"] local Font_Features = os.resultof("otfinfo -f " ..

If you run the file as context test.cld --font="/path/to/font" this works, and you get a table Feature_Table={ ["aalt"]="Access All Alternates", ["c2sc"]="Small Capitals From Capitals"} etc. CODE for name, _ in pairs(Feature_Table) do Context_Name = "f:" .. name Parsed_Features[name] = Context_Name context.definefontfeature( { Context_Name }, { name="yes" } ) end COMMENTS This should produce a lua table with ConTeXt fontfeatures and define those features. The table appears to be correct: Parsed_Features={ ["aalt"]="f:aalt", ["c2sc"]="f:c2sc"} etc. So I expected that this should be equivalent to \definefontfeature [f:aalt] [aalt=yes] and return a list of defined features. CODE local Test_String = [[ ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz 1234567890 1/4 2/8 3/9 ffi ft fi fl ffl ]] local Font_Name = os.resultof("otfinfo -a " ..

Expectation: this should return a list of all features and their descriptions as a lua table. If you run the file as

this works, and you get a table

Also, (4) you need to load the font without any features except the ones that enable node mode. So, now you need to wikify ...

Thank you, Hans! Yes, I had a hunch that most of this was unnecessary because the information is already there. I also thought it would be convenient to have a helper script that could display everything before I decide whether I want to add a font to my texmf-font tree... Will play with this and then wikify!
