From 9f6cba5c0370aee2f9803abbc35ab7e67f57ee84 Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Tue, 1 Nov 2016 06:58:18 +0100 Subject: globbing supports character classes now and ^EN string building construct to escape glob patterns * globbing is fnmatch(3) compatible, now on every supported platform. * which means that escaping of glob patterns is possible now. ^ENq has been introduced to ease this task. * This finally allows you to pass unmodified filenames to EB. Previously it was impossible to open file names containing glob wildcards. * this was achieved by moving from GPattern to GRegex as the underlying implementation. * The glob pattern is converted to a regular expression before being compiled to a GRegex. This turned out to be trickier than anticipated (~140 lines of code) and has a runtime penalty of course (complexity is O(2*n) over the pattern length). It is IMHO still better than the alternatives, like importing external code from libiberty, which is potentially non-cross-platform. * Using GRegex also opens the potential of supporting brace "expansions" later in the form of glob pattern constructs (they won't actually expand but match alternatives). * is_glob_pattern() has been simplified and moved to Globber::is_pattern(). It makes sense to reuse the Globber class namespace instead of using plain functions for functions working on glob patterns. * The documentation has a new subsection on glob patterns now. * Testsuite extended with glob pattern test cases --- lib/session.tes | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib') diff --git a/lib/session.tes b/lib/session.tes index 5f1ceab..598dbca 100644 --- a/lib/session.tes +++ b/lib/session.tes @@ -19,7 +19,7 @@ EU[session.path]Q[$SCITECOCONFIG]/.teco_session ' EJ< %.bEB ESGETFIRSTVISIBLELINEU.[fvline] ESGETXOFFSETU.[xoff] .U.[dot] - :@EU.[session]{EBQ* \.[fvline]ESSETFIRSTVISIBLELINE \.[xoff]ESSETXOFFSET \.[dot]:J^J} + :@EU.[session]{EBN* \.[fvline]ESSETFIRSTVISIBLELINE \.[xoff]ESSETXOFFSET \.[dot]:J^J} :Q*"= -1U.u ' > !
