css

Some css code to create 16x16 circles.
(based on GitHub's colour codes)

.circle{height:16px;width:16px;border-radius:50%;display:inline-block}.ada{background-color:#02f88c}.awk{background-color:#ccc}.bat{background-color:#c1f12e}.c{background-color:#555}.clj{background-color:#db5855}.cs{background-color:#178600}.css{background-color:#563d7c}.cxx{background-color:#f34b7d}.el{background-color:#c065db}.erl{background-color:#b83998}.f{background-color:#4d41b1}.go{background-color:#375eab}.hs{background-color:#5e5086}.htm{background-color:#e34c26}.java{background-color:#b07219}.js{background-color:#f1e05a}.jl{background-color:#a270ba}.lua{background-color:navy}.m4{background-color:#ccc}.mak{background-color:#427819}.pas{background-color:#e3f171}.pl{background-color:#0298c3}.php{background-color:#4f5d95}.ps{background-color:#da291c}.ps1{background-color:#012456}.py{background-color:#3572a5}.r{background-color:#198ce7}.rb{background-color:#701516}.rs{background-color:#dea584}.sas{background-color:#b34936}.scala{background-color:#c22d40}.scm{background-color:#1e4aec}.sed{background-color:#64b970}.sh{background-color:#89e051}.sql{background-color:#ccc}.tcl{background-color:#e4cc98}.tex{background-color:#3d6117}.vb{background-color:#945db7}.vim{background-color:#199f4b}.xml{background-color:#ccc}

Neither CSS geometric shapes nor table layout render in Blogger's editor, only as viewed in Preview mode, for that reason I primarily utilise indexed .gif icons, and html 4.1 coding for the few tables found on this log; it goes without saying that terminal-based browsers, as links-2.7 and w3m-0.5.3, which include rudimentary table support, do not however support CSS.

As an example I appended the above CSS code with
'.black{background-color:#000}', and this now renders
the mobile version's "homepage" icon.

<b:widget id='HTML2' locked='false' mobile='only' title='' type='HTML'>
<b:widget-settings>
<b:widget-setting name='content'><![CDATA[<div style="padding: 10px; text-align: right;"><a href="http://nurmi-labs.blogspot.com/p/homepage.html?m=1" target="_blank" title="homepage"><span class="circle black"></span></a> </div>]]></b:widget-setting>
</b:widget-settings>

I infrequently add new content to this log - RSS and Atom Feed
being generated in real-time - I've changed the homepage head
element, to not load the former's link; commenting also on this
log being disabled, the OpenID server and delegate links seemed
superfluous.

<head>

<b:include data='blog' name='all-head-content'/>

the above theme code was modified as follows

<head>

<data:blog.feedLinks/>

<b:if cond='data:blog.url == data:blog.homepageUrl'>

</b:if>

with modification

sh-4.2$ perl -MLWP::Simple -e 'getprint "http://nurmi-labs.blogspot.com/"' > b.html

sh-4.2$ head -n 15 b.html | tail -n +7

quadcode

There is a package for compiling Tcl bytecode into LLVM IR.

This depends on the wrapper for the C interface written by J. Decoster.

Slackware-14.2 contains adequate clang, LLVM, and Tcl versions.

On MS using VS the minimum version of VS2015 (MSVC140) should
be adequate for, e.g., LLVM 3.8.0 installation, where I cite that release
as pertains to its availability also via the mentioned Slackware version;
if one is inclined to compare code generation from two different OSes.

A search on Hackage reveals various authors have implemented both
ffi and pure Haskell bindings for the LLVM; also analysis, pretty printer
and tools' packages

Wiki Page: https://wiki.tcl.tk/40985

Presently I'm running Slackware-14.0 and do not have access to a
recent MS release adequate for a VS2015 or newer installation, so
I won't be pursuing any testing, but I thought the development was
interesting enough to Post a log entry on the work.

xs

System: Slackware Linux (version 14.2)

Slackware-14.2 comes with sufficiently recent libffi and readline packages, and the remaining dependencies as gc, ninja (optional re2c), python3, and meson, can be created as packages
from the scripts available at SlackBuilds.org.

We'll see if boost-1.59 can work, as 1.60 is stated in the INSTALL file as the minimum version number.
