- https://en.wikipedia.org/wiki/Text_editor - a type of computer program that edits plain text. Such programs are sometimes known as "notepad" software, following the naming of Microsoft Notepad. Text editors are provided with operating systems and software development packages, and can be used to change files such as configuration files, documentation files and programming language source code.
- https://en.wikipedia.org/wiki/TECO_(text_editor) - Text Editor & COrrector is both a character-oriented text editor and a programming language, that was developed in 1962 for use on Digital Equipment Corporation computers, and has since become available on PCs and Unix. Dan Murphy developed TECO while a student at the Massachusetts Institute of Technology (MIT).
According to Murphy, the initial acronym was "Tape Editor and Corrector" because "punched paper tape was the only medium for the storage of program source on our PDP-1. There was no hard disk, floppy disk, magnetic tape (magtape), or network." By the time TECO was made available for general use, the name had become "Text Editor and Corrector," since even the PDP-1 version by then supported other media. It was subsequently modified by many other people and is a direct ancestor of Emacs, which was originally implemented in TECO macros.
- https://en.wikipedia.org/wiki/QED_(text_editor) - a line-oriented computer text editor that was developed by Butler Lampson and L. Peter Deutsch for the Berkeley Timesharing System running on the SDS 940. It was implemented by L. Peter Deutsch and Dana Angluin between 1965 and 1966. QED (for "quick editor") addressed teleprinter usage, but systems "for CRT displays [were] not considered, since many of their design considerations [were] quite different."
- https://en.wikipedia.org/wiki/Ed_(text_editor) - a line editor for the Unix operating system. It was one of the first parts of the Unix operating system that was developed, in August 1969. It remains part of the POSIX and Open Group standards for Unix-based operating systems, alongside the more sophisticated full-screen editor vi.

- https://en.wikipedia.org/wiki/COCOA_(digital_humanities) - was an early text file utility and associated file format for digital humanities, then known as humanities computing. It was approximately 4000 punched cards of FORTRAN and created in the late 1960s and early 1970s at University College London and the Atlas Computer Laboratory in Harwell, Oxfordshire. Functionality included word-counting and concordance building.
The COCOA file format bears at least a passing similarity to the later markup languages such as SGML and XML. A noticeable difference with its successors is that COCOA tags are flat and not tree structured. In that format, every information type and value encoded by a tag should be considered true until the same tag changes its value. Members of the Text Encoding Initiative community maintain legacy support for COCOA, although most in-demand texts and corpora have already been migrated to more widely understand formats such as TEI XML
SGML descended from IBM's Generalized Markup Language (GML), which Charles Goldfarb, Edward Mosher, and Raymond Lorie developed in the 1960s. Goldfarb, editor of the international standard, coined the “GML” term using their surname initials. Goldfarb also wrote the definitive work on SGML syntax in "The SGML Handbook". The syntax of SGML is closer to the COCOA format. As a document markup language, SGML was originally designed to enable the sharing of machine-readable large-project documents in government, law, and industry. Many such documents must remain readable for several decades—a long time in the information technology field. SGML also was extensively applied by the military, and the aerospace, technical reference, and industrial publishing industries. The advent of the XML profile has made SGML suitable for widespread application for small-scale, general-purpose use.
- https://en.wikipedia.org/wiki/Document_type_definition - a set of markup declarations that define a document type for an SGML-family markup language (SGML, XML, HTML). A Document Type Definition (DTD) defines the legal building blocks of an XML document. It defines the document structure with a list of legal elements and attributes. A DTD can be declared inline inside an XML document, or as an external reference.
XML uses a subset of SGML DTD.
As of 2009, newer XML namespace-aware schema languages (such as W3C XML Schema and ISO RELAX NG) have largely superseded DTDs. A namespace-aware version of DTDs is being developed as Part 9 of ISO DSDL. DTDs persist in applications that need special publishing characters, such as the XML and HTML Character Entity References, which derive from larger sets defined as part of the ISO SGML standard effort.

- w3c: XQuery - a query and functional programming language that queries and transforms collections of structured and unstructured data, usually in the form of XML, text and with vendor-specific extensions for other data formats (JSON, binary, etc.). The language is developed by the XML Query working group of the W3C. The work is closely coordinated with the development of XSLT by the XSL Working Group; the two groups share responsibility for XPath, which is a subset of XQuery.
- http://www.xembly.org/ Xembly is an Assembly-like imperative programming language for data manipulation in XML documents. It is a much simplier alternative to XSLT and XQuery. Read this blog post for a more detailed explanation: Xembly, an Assembly for XML.
- XML Linking Language (XLink)
- https://en.wikipedia.org/wiki/XLink - an XML markup language and W3C specification that provides methods for creating internal and external links within XML documents, and associating metadata with those links.
- http://en.wikipedia.org/wiki/XSL - Extensible Stylesheet Language (XSL) is used to refer to a family of languages used to transform and render XML documents.

But flpsed lets you add arbitrary text lines to existing PostScript documents (PostScript is a registered trademark of Adobe Systems Incorporated). Added lines can later be reedited with flpsed. Using pdftops, which is part of xpdf one can convert PDF documents to PostScript and also add text to them. flpsed is useful for filling in forms, adding notes etc. GsWidget is now part of flpsed.
flpsed is released under the GPL.
- https://sourceforge.net/projects/pdfshuffler - a small python-gtk application, which helps the user to merge or split pdf documents and rotate, crop and rearrange their pages using an interactive and intuitive graphical interface. It is a frontend for python-pyPdf.
- https://github.com/2mol/pboy - a small .pdf management utility. It is borne out of the frustration of having a dowload folder full of PDFs with names like 'I08.pdf', '1412.4880.pdf' and so on. Since I want to save some of these files for later reading, it would be helpful to have more descriptive filenames. This tool helps with renaming those files. It will rename/move documents to a specified folder, and it even gives some filename suggestions by looking at the file content and the pdf metadata.

- Fountain - a simple markup syntax for writing, editing and sharing screenplays in plain, human-readable text. Fountain allows you to work on your screenplay anywhere, on any computer or tablet, using any software that edits text files. Taking its cues from John Gruber’s Markdown, Fountain files are eminently readable. When special syntax is required, it is straightforward and intuitive. Even when viewed as plain text, your screenplay feels like a screenplay. Fountain supports everything a screenwriter is likely to need in the early, creative phases of writing. Not included are production features such as MOREs, CONTINUEDs, revision marks, locked pages, or colored pages. Because it’s just text, Fountain is also a great format for archiving screenplays without worry of file-format obsolescence or incompatibility.
