What is pl file?
File type category:
Text file
Program executable file
Source code and script file
Date updated: December 31, 2024
File extension pl is sometimes used in Perl, a stable, cross platform programming language. It is used for mission critical projects in the public and private sectors and is widely used to program web applications of all needs. It is rare on the web, because Perl scripts are usually served as cgi.
Perl is popular enough that there are a few out there, though. Although Perl won't let you insert code into static HTML pages, it does have a library specifically for generating web pages.
Using the Perl CGI library, you can generate all the parts of each web page using a specialized function; a command to generate the tag etc. So, you don't have to use "print" to generate every single line of code, which must be handy.
MIME types:
text/x-script.perl
text/plain

PROLOG language source code file
File type category:
Source code and script file
Date updated: August 3, 2017
The pl file extension is associated with the PROLOG programming language. The .pl file stores Prolog source code.
Prolog is a logic programming language. It is a general purpose language often associated with artificial intelligence and computational linguistics. It has a purely logical subset, called "pure Prolog", as well as a number of extralogical features.
Having its roots in formal logic, and unlike many other programming languages, Prolog is declarative: The program logic is expressed in terms of relations, and execution is triggered by running queries over these relations. Relations and queries are constructed using Prolog's single data type, the term. Relations are defined by clauses. Given a query, the Prolog engine attempts to find a resolution refutation of the negated query. If the negated query can be refuted, i.e., an instantiation for all free variables is found that makes the union of clauses and the singleton set consisting of the negated query false, it follows that the original query, with the found instantiation applied, is a logical consequence of the program. This makes Prolog (and other logic programming languages) particularly useful for database, symbolic mathematics, and language parsing applications. Because Prolog allows impure predicates, checking the truth value of certain special predicates may have some deliberate side effect, such as printing a value to the screen. This permits the programmer to use some amount of conventional imperative programming when the logical paradigm is inconvenient.
The language was first conceived by a group around Alain Colmerauer in Marseille, France, in the early 1970s, while the first compiler was written by David H. D. Warren in Edinburgh, Scotland. Prolog was one of the first logic programming languages, and remains among the most popular such languages today, with many free and commercial implementations available. While initially aimed at natural language processing, the language has since then stretched far into other areas like theorem proving, expert systems, games, automated answering systems, ontologies and sophisticated control systems, and modern Prolog environments support the creation of graphical user interfaces, as well as administrative and networked applications.

TeX property list font metric file
File type category:
Various data file
Date updated: March 4, 2013
The PL file extension is also used by TeX, a typesetting system designed and mostly written by Donald Knuth. Together with the METAFONT language for font description and the Computer Modern typefaces, it was designed with two main goals in mind: to allow anybody to produce high-quality books using a reasonable amount of effort, and to provide a system that would give the exact same results on all computers, now and in the future. A *.pl file used in Tex contains property list font metric.
