15<title>Introducing Tablespoon</title>
16<description>&lt;p&gt;&lt;a href="https://git.peppe.rs/languages/tbsp"&gt;tbsp&lt;/a&gt; (tree-based
17source-processing language) is an awk-like language that operates on
18tree-sitter syntax trees. To motivate the need for such a program, we
19could begin by writing a markdown-to-html converter using
20&lt;code&gt;tbsp&lt;/code&gt; and &lt;a
21href="https://github.com/tree-sitter-grammars/tree-sitter-markdown"&gt;tree-sitter-md&lt;/a&gt;.
22We need some markdown to begin with:&lt;/p&gt;
23&lt;pre&gt;&lt;code&gt;# 1 heading
24
25content of first paragraph
26
27## 1.1 heading
28
29content of nested paragraph&lt;/code&gt;&lt;/pre&gt;
30&lt;p&gt;For future reference, this markdown is parsed like so by
31tree-sitter-md (visualization generated by &lt;a
32href="https://git.peppe.rs/cli/tree-viz"&gt;tree-viz&lt;/a&gt;):&lt;/p&gt;
33&lt;pre&gt;&lt;code&gt;document

36| | | atx_h1_marker &amp;quot;#&amp;quot;

44| | | paragraph
45| | | | inline &amp;quot;content of nested paragraph&amp;quot;&lt;/code&gt;&lt;/pre&gt;
46&lt;p&gt;Onto the converter itself. Every &lt;code&gt;tbsp&lt;/code&gt; program is written
47as a collection of stanzas. Typically, we start with a stanza like
48so:&lt;/p&gt;
49&lt;pre&gt;&lt;code&gt;BEGIN {
50 int depth = 0;
51
52 print(&amp;quot;&amp;lt;html&amp;gt;\n&amp;quot;);
53 print(&amp;quot;&amp;lt;body&amp;gt;\n&amp;quot;);
54}&lt;/code&gt;&lt;/pre&gt;
55&lt;p&gt;The stanza begins with a “pattern”, in this case, &lt;code&gt;BEGIN&lt;/code&gt;,
56and is followed a block of code. This block specifically, is executed
57right at the beginning, before traversing the parse tree. In this
58stanza, we set a “depth” variable to keep track of nesting of markdown
59headers, and begin our html document by printing the
60&lt;code&gt;&amp;lt;html&amp;gt;&lt;/code&gt; and &lt;code&gt;&amp;lt;body&amp;gt;&lt;/code&gt; tags.&lt;/p&gt;
61&lt;p&gt;We can follow this stanza with an &lt;code&gt;END&lt;/code&gt; stanza, that is
62executed after the traversal:&lt;/p&gt;
63&lt;pre&gt;&lt;code&gt;END {
64 print(&amp;quot;&amp;lt;/body&amp;gt;\n&amp;quot;);
65 print(&amp;quot;&amp;lt;/html&amp;gt;\n&amp;quot;);
66}&lt;/code&gt;&lt;/pre&gt;
67&lt;p&gt;In this stanza, we close off the tags we opened at the start of the
68document. We can move onto the interesting bits of the conversion
69now:&lt;/p&gt;
70&lt;pre&gt;&lt;code&gt;enter section {
71 depth += 1;
72}
73leave section {
74 depth -= 1;
75}&lt;/code&gt;&lt;/pre&gt;
76&lt;p&gt;The above stanzas begin with &lt;code&gt;enter&lt;/code&gt; and
77&lt;code&gt;leave&lt;/code&gt; clauses, followed by the name of a tree-sitter node
78kind: &lt;code&gt;section&lt;/code&gt;. The &lt;code&gt;section&lt;/code&gt; identifier is
79visible in the tree-visualization above, it encompasses a
80markdown-section, and is created for every markdown header. To
81understand how &lt;code&gt;tbsp&lt;/code&gt; executes above stanzas:&lt;/p&gt;
82&lt;pre&gt;&lt;code&gt;document ... depth = 0
83| section &amp;lt;-------- enter section (1) ... depth = 1
84| | atx_heading
85| | | inline
86| | paragraph
87| | | inline
88| | section &amp;lt;----- enter section (2) ... depth = 2
89| | | atx_heading

93| | | &amp;lt;----------- leave section (2) ... depth = 1
94| | &amp;lt;-------------- leave section (1) ... depth = 0 &lt;/code&gt;&lt;/pre&gt;
95&lt;p&gt;The following stanzas should be self-explanatory now:&lt;/p&gt;
96&lt;pre&gt;&lt;code&gt;enter atx_heading {

132build and run:&lt;/p&gt;
133&lt;pre&gt;&lt;code&gt;cargo build --release
134./target/release/tbsp --help&lt;/code&gt;&lt;/pre&gt;
135&lt;p&gt;&lt;code&gt;tbsp&lt;/code&gt; requires three inputs:&lt;/p&gt;
136&lt;ul&gt;
137&lt;li&gt;a &lt;code&gt;tbsp&lt;/code&gt; program, referred to as “program file”&lt;/li&gt;
138&lt;li&gt;a language&lt;/li&gt;
139&lt;li&gt;an input file or some input text at stdin&lt;/li&gt;
140&lt;/ul&gt;
