From fea1afaa5de642185dc899fad5666da249e2776a Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Sat, 7 Oct 2023 21:27:56 +0000 Subject: Include .EX/.EE in the MACRO OVERVIEW and improve its description. It is supported by all major man(7) implementations that G. Branden Robinson and myself are aware of, so calling it "non-portable" can no longer be justified. Using it becomes increasingly more common, so calling it "non-standard" is now misleading. It is certainly useful and not deprecated. While here, also remove the word "non-standard" from the descriptions of several other macros because it is slightly confusing. A formal standard for the man(7) language does not exist. Arguably, Version 7 AT&T UNIX used to be a de-facto standard, but its influence has been waning for 40 years, and various features that Version 7 did not support are now widely used. --- man.7 | 28 +++++++++++++++------------- 1 file changed, 15 insertions(+), 13 deletions(-) (limited to 'man.7') diff --git a/man.7 b/man.7 index b81a0f01..c9b8a5ec 100644 --- a/man.7 +++ b/man.7 @@ -97,10 +97,11 @@ but can be found in the alphabetical reference below. .It Ic SH Ta section header (one line) .It Ic SS Ta subsection header (one line) .It Ic PP Ta start an undecorated paragraph (no arguments) -.It Ic RS , RE Ta reset the left margin: Op Ar width .It Ic IP Ta indented paragraph: Op Ar head Op Ar width .It Ic TP Ta tagged paragraph: Op Ar width .It Ic PD Ta set vertical paragraph distance: Op Ar height +.It Ic EX , EE Ta display an example (no arguments) +.It Ic RS , RE Ta reset the left margin: Op Ar width .It Ic in Ta additional indent: Op Ar width .El .Ss Physical markup @@ -162,7 +163,9 @@ This has no effect unless the tabulator positions were changed with the .Ic ta request. .It Ic EE -This is a non-standard Version 9 +End an example block started with +.Ic EX . +This is a Version 9 .At extension later adopted by GNU.
