Brian Kernighan said hello, asked how their US visit was going, and dropped off <a href=\"https:\/\/github.com\/onetrueawk\/awk\/commit\/d322b2b5fc16484affb09e86b044596a2e347853\">hundreds of lines of code<\/a> that could add Unicode support for AWK, the text-parsing tool he helped create for Unix at Bell Labs in 1977.<\/p>\n<p>&#8220;I have tested this a fair amount but clearly more tests are needed,&#8221; Kernighan wrote in the email, posted in late May as a kind of <a href=\"https:\/\/github.com\/onetrueawk\/awk\/commit\/9ebe940cf3c652b0e373634d2aa4a00b8395b636\">pseudo-commit<\/a>&nbsp;on the onetrueawk repo by longtime maintainer Arnold Robbins. &#8220;Once I figure out how &#8230; I will try to submit a pull request. I wish I understood git better, but in spite of your help, I still don&#8217;t have a proper understanding, so this may take a while.&#8221;<\/p>\n<p>Kernighan is the &#8220;K&#8221; in <a href=\"https:\/\/en.wikipedia.org\/wiki\/AWK#Versions_and_implementations\">AWK<\/a>, a special-purpose language for extracting and manipulating language that was key to Unix&#8217;s pipeline features and interoperability between systems. A working <code>awk<\/code> function (AWK is the language, <code>awk<\/code> the command to invoke it) is critical to both Standard UNIX Specification and IEEE POSIX certification for interoperability. There are countless variants of <code>awk<\/code>\u2014including modern derivations with support for Unicode\u2014but &#8220;One True AWK,&#8221; sometimes known as <code>nawk<\/code>, is a kind of canonical version based on Kernighan&#8217;s 1985 book&nbsp;<em>The AWK Programming Language<\/em> and his subsequent input.<\/p>\n<figure class=\"image shortcode-img center full\"><img alt=\"Copies of <em>The C Programming Language<\/em> in their native campus bookstore environment, written by Brian Kernighan and Dennis Ritchie (RIP).&#8221; src=&#8221;https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2009\/03\/c-programming.jpg&#8221; width=&#8221;300&#8243; height=&#8221;169&#8243;><figcaption class=\"caption\">\n<div class=\"caption-text\">Copies of <em>The C Programming Language<\/em> in their native campus bookstore environment, written by Brian Kernighan and Dennis Ritchie (RIP).<\/div>\n<\/figcaption><\/figure>\n<p>Kernighan is also the &#8220;K&#8221; in &#8220;K&amp;R C,&#8221; the foundational 1978 book <em>The C Programming Language&nbsp;<\/em>he cowrote with Dennis Ritchie that sticks with programmers, mentally and in dog-eared paper form.

That book gave birth to &#8220;the one true brace style,&#8221; the endless debate that goes with it, and the structure underpinning every modern programming language.<\/p>\n<aside class=\"ad_wrapper\" aria-label=\"In Content advertisement\"> <span class=\"ad_notice\">Advertisement <\/span> <\/aside>\n<p>Kernighan also <a href=\"https:\/\/www.bell-labs.com\/institute\/blog\/invention-unix\/\">named Unix<\/a> and first demonstrated the &#8220;Hello, world&#8221; code example. He spoke with Ars Technica&#8217;s Richard Jensen for a <a href=\"https:\/\/arstechnica.com\/gadgets\/2019\/08\/unix-at-50-it-starts-with-a-mainframe-a-gator-and-three-dedicated-researchers\/\">50th anniversary history of Unix<\/a>.<\/p>\n<p>The <a href=\"https:\/\/github.com\/onetrueawk\/awk\">onetrueawk repository<\/a>, where Kernighan appeared in late May, is a relatively quiet place, with 21 contributors, 46 GitHub users watching, and commits coming every few months. As noted by <a href=\"https:\/\/www.theregister.com\/2022\/08\/23\/universal_unix_tool_awk_gets\/\">The Register<\/a>, Kernighan&#8217;s Unicode fix came to light mostly because it was mentioned in an interview with the professor by <a href=\"https:\/\/www.youtube.com\/watch?v=GNyQxXw_oMQ\">YouTube channel Computerphile<\/a>.<\/p>\n<figure class=\"video\">\n<div class=\"wrapper\"><iframe loading=\"lazy\" type=\"text\/html\" width=\"980\" height=\"550\" src=\"https:\/\/www.youtube.com\/embed\/GNyQxXw_oMQ?start=0&amp;wmode=transparent\" frameborder=\"0\" allowfullscreen>[embedded content]<\/iframe><\/div><figcaption class=\"caption\">\n<div class=\"caption-text\">Brian Kernighan speaking with Computerphile about his work, recent and historic.<\/div>\n<\/figcaption><\/figure>\n<p>&#8220;It&#8217;s always been an embarrassment that AWK only worked with ASCII, or maybe 8-bit inputs, but it doesn&#8217;t really handle Unicode at all,&#8221; Kernighan tells interviewer professor David Brailsford. &#8220;A few months ago, I spent some time working with (laughs) an incredibly old program. I have it at this point where it will actually handle UTF-8 input and output so that you can have regular expressions that, you know, pick up Japanese characters, things like that.&#8221;<\/p>\n<p>Kernighan, now 80, offhandedly mentions in the interview that he has also patched something &#8220;quick and dirty&#8221; to let AWK handle CSV files.<\/p>\n<p> READ MORE <a
