<p>Download and uncompress a trace:</p>
<pre><code>wget https://holtrace.cr.yp.to/prime.50.gz
gunzip prime.50
</code></pre>
<p>Start a HOL Light session
(not reusing a pre-HOLTrace session):</p>
<pre><code>hol.sh
</code></pre>
<p>In that session, verify the trace:</p>
<pre><code>holtrace_restore !theorems "prime.50";;
</code></pre>
<p>The expected outputs are many lines that start <code>matching</code>
and then the following, with more lines in place of <code>...</code>:</p>
<pre><code>types: 597
terms: 176388
theorems: 91115
inferences: 91115
axioms: 3 = matching 3 + creating 0
typedefs: 6 = matching 6 + creating 0
constants: 82 = matching 82 + creating 0
named thms: 327 = matching 327 + creating 0
tag / 0.000000 seconds 327 occurrences
...
tag t 0.000000 seconds 91115 occurrences
total 0.000000 seconds
val it : unit = ()
</code></pre>
<p>You can also try <code>holtrace_restore_time</code> instead of <code>holtrace_restore</code>;
then there will be actual timings instead of <code>0.000000 seconds</code>.</p>
<p>Inspect the restored <code>ONE_OR_PRIME</code> theorem:</p>
<pre><code>holtrace_restore_name2thm "ONE_OR_PRIME";;
</code></pre>
<p>The expected output is the following:</p>
<pre><code>val it : thm =
|- forall p.
p = 1 \/ prime p <=> (forall n. n divides p ==> n = 1 \/ n = p)
</code></pre>
<p>Check that the restored theorem matches the theorem from the HOL Light standard library:</p>
<pre><code>equals_thm it ONE_OR_PRIME;;
</code></pre>
<p>The expected output is <code>val it : bool = true</code>.</p>
<p>Outside the HOL Light session,
verify the same trace from the command line:</p>
<pre><code>./holtrace-verify-simple < prime.50
./holtrace-verify < prime.50
</code></pre>
<p>The expected output is</p>
<pre><code>verified 2399423 bytes, 359543 lines, 597 types, 176388 terms, 91115 infs, 91115 thms, 6 typedefs
</code></pre>
<p>from <code>holtrace-verify-simple</code>,
and the same from <code>holtrace-verify</code>.</p>
<p>Check that the trace is already pruned
down to what is needed for the <code>ONE_OR_PRIME</code> theorem:</p>
<pre><code>./holtrace-prune ONE_OR_PRIME < prime.50 | cmp - prime.50
</code></pre>
<p>The expected output is nothing.</p>
<p>Convert the trace to a TeX file:</p>
<pre><code>./holtrace2tex < prime.50 > prime.tex
xelatex prime
</code></pre>
<p>The last theorem on the last page of the resulting <code>prime.pdf</code> is expected to say the following:
"Theorem (ONE_OR_PRIME). Fix <em>p</em> ∈ ℕ. Then <em>p</em> = 1 or <em>p</em> is prime if and only if we have <em>n</em> = 1 or <em>n</em> = <em>p</em> for each <em>n</em> ∈ ℕ such that <em>n</em> divides <em>p</em>."</p>
<p>Test some libraries used by the Python scripts:</p>
<pre><code>./type.py
./term.py
./ptparse.py
</code></pre>
<p>The expected outputs are <code>test type</code> and <code>test term</code> and <code>test ptparse</code>.</p>
<p>Try the built-in suite of test traces:</p>
<pre><code>./testtraces < testtraces.in | cmp - testtraces.exp
</code></pre>
<p>This takes 23 seconds
on <a href="install.html"><code>rome1</code></a>.
The expected output is nothing.</p><hr><font size=1><b>Version:</b>
