V_REGEXFILES recursively searches for files matching a pattern tok=(regex,root)
Usage: (1) v_regexfiles('\.m$',[],'r') % find all files *.m in current folder tree
Inputs:
regex regular expression giving the pattern to match (not including root path)
root path to initial folder [default: current folder]
m 'n' non recursive search [default]
'r' recursive search through tree starting at root
Outputs:
tok cell array listing the file paths sorted alphabetically (not including the root path)
Regular expressions:
Each character matches itself except for +?.*^$()[]{}|\
Precede these by \ to avoid their special meanings
Use '/' for the separator in file paths
. Any single character, including white space
[xyz] Any character contained within the brackets: x or y or z
[^xyz] Any character not contained within the brackets: anything but x or y or z
[x-z] Any character in the range of x through z
\s Any white-space character; equivalent to [ \f\n\r\t\v]
\S Any non-whitespace character; equivalent to [^ \f\n\r\t\v]
\w Any alphabetic, numeric, or underscore character; equivalent to [a-zA-Z_0-9]
\W Any character that is not alphabetic, numeric, or underscore; equivalent to [^a-zA-Z_0-9]
\d Any numeric digit; equivalent to [0-9]
\D Any nondigit character; equivalent to [^0-9]
\oN or \o{N} Character of octal value N
\xN or \x{N} Character of hexadecimal value N
(...) Group
cat|dog Alternatives 'cat' or 'dog'
^ match start of full file name (if first character)
$ match end of full file name (if last character)
\< match start of word
\> match end of word
? match preceeding character 0 or 1 times
* match preceeding character or group >=0 times
+ match preceeding character or group >=1 times
{m} match preceeding character or group exactly m times
{m,} match preceeding character or group >=m times
{m,n} match preceeding character or group >=m and <=n times0001 function tok=v_regexfiles(regex,root,m) 0002 %V_REGEXFILES recursively searches for files matching a pattern tok=(regex,root) 0003 % 0004 % Usage: (1) v_regexfiles('\.m$',[],'r') % find all files *.m in current folder tree 0005 % 0006 % Inputs: 0007 % regex regular expression giving the pattern to match (not including root path) 0008 % root path to initial folder [default: current folder] 0009 % m 'n' non recursive search [default] 0010 % 'r' recursive search through tree starting at root 0011 % 0012 % Outputs: 0013 % tok cell array listing the file paths sorted alphabetically (not including the root path) 0014 % 0015 % Regular expressions: 0016 % Each character matches itself except for +?.*^$()[]{}|\ 0017 % Precede these by \ to avoid their special meanings 0018 % Use '/' for the separator in file paths 0019 % .
