How to use MusicXmlParser in jFugue 5.0? - jfugue
I'm trying to parse a Staccato Pattern into MusicXml. However, it's not working, as the parsed MusicXml contains almost nothing. I don't know if it's due to something wrong with my Staccato string, or the MusicXmlParser.
Here's my code, including the Staccato string:
public class TestMusicXml {
public static void main(String[] args) {
Pattern p = new Pattern(

2017-07-16 05:36:16.674 1 D writing music xml:
JFugue MusicXMLRenderer
So the parsed musicXml result is:
<?xml version="1.0"?>
<!DOCTYPE score-partwise PUBLIC "-//Recordare//DTD MusicXML 1.1 Partwise//EN" "http://www.musicxml.org/dtds/partwise.dtd">
<score-partwise><identification><creator type="software">JFugue MusicXMLRenderer</creator></identification><part-list /></score-partwise>
All my notes are gone. What am I missing?
Thanks in advance.
It's buried too far in JFugue's Download page to be immediately obvious, but: "Please note that there is no current implementation for MusicXmlParserListener. JFugue still needs: a MusicXmlParserListener updated for JFugue 5.0, more thorough tests for MusicXMLParser, ..."
(I'll work on making that more obvious for others who download the code).
The MusicXML functionality in JFugue is contributed by volunteers, and there have been some gaps in updating the code for the most recent version of MusicXML and the most recent version of JFugue.

Find references to files, recursively
In a project where XML/JS/Java files can contain references to other such files, I'd like to be able to have a quick overview of what has to be carefully checked, when one file has been updated.
So, it means I need to eventually have a look at all files referencing the modified one, and all files referencing files which refer to the modified one, etc. (recursively on matched files).
For one level, it's quite simple:
grep -E -l -o --include=*.{xml,js,java} -r "$FILE" . | xargs -n 1 basename
But how can I automate that to match (grand-(grand-))parents?
And how can that be, maybe, made more readable? For example, with a tree structure?
For example, if the file that interests me is called modified.js...
show-referring-files-to modified.js
... I could wish such an output:
some-file-with-ref-to-modified.xml
|__ a-file-referring-to-some-file-with-ref-to-modified.js
another-one-with-ref-to-modified.xml
|__ a-file-referring-to-another-one-with-ref-to-modified.js
|__ a-grand-parent-file-having-ref-to-ref-file.xml
|__ another-file-referring-to-another-one-with-ref-to-modified.js
or any other output (even flat) which allows for quickly checking which files are potentially impacted by a change.

| | | | | | |__ahrufrp.xml
(...)
I'd use a shell function (for the recursion) inside an shell script:
Assuming the filenames are unique have no characters that need escaping in them:
File: /usr/local/bin/show-referring-files-to
#!/bin/sh
get_references() {
grep -F -l --include=*.{xml,js,java} -r "$1" . | grep -v "$3" | while read -r subfile; do
#read each line of the grep result into the variable subfile
subfile="$(basename "$subfile")"
echo "$2""$subfile"
get_references "$subfile" ' '"$2" "$3"'\|'"$subfile"
done
}
while test $# -gt 0; do
#loop so more than one file can be given as argument to this script
echo "$1"
get_references "$1" '|__' "$1"
shift
done
There still are lots of performance enhancements possible.
Edit: Added $3 to prevent infinite-loop.
lftp upload files inside different folders
I need to upload files in different folders with same name, recursively to a remote folder. Here a example. Local |-app1-1 | |-src | |-img | |-static | |-app1-2 <------Upload from this | |-file1-1 | |-file1-2 |-app2-1 | |-src | |-img | |-static | |-app2-2 <------Upload from this | |-file2-1 | |-file2-2 Here the remote result I need. Remote Result |-folder1 |-folder2 |-folder3 |-static | |-app1-2 <------Upload from this | | |-file1-1 | | |-file1-2 | | | |-app2-2 <------Upload from this | | |-file2-1 | | |-file2-1 I have testing with scripts like this: - > lftp -e "mirror --include ^static/ --exclude ^\.git.* -eRv $CI_PROJECT_DIR Remote Result/static; quit;" sftp://$CREDENTIALS But this generate a output not desired: Remote Result |-folder1 |-folder2 |-folder3 |-static | |-app1-1 <------Upload from this | | |-static | | |-app1-2 | | |-file1 | | |-file2 ...... (Same other folder)

I only zeropad the day and month (1/1/2016 -> 2016-01-01), not the hours or minutes. There is no sanity checking for missing or distorted datetimes. Add = to comparisons if needed (ie. > -> >=).
Using Closure_tree gem instead of Awesome nested set
Hi I followed the link to set up closure_tag gem.
When i tried to use closure_tree syntax in the following way (newStructure.find_or_create_by_path(parent) instead of newStructure.move_to_child_of(parent)) ... got the following error :
"Can't mass-assign protected attributes: ancestor, descendant, generations"
is this the correct way of using newStructure.find_or_create_by_path(parent) ?
def self.import(path)
newStructure = FileOrFolder.find(:first, :conditions=>["fullpath = ?", path])
if newStructure
return newStructure
end
newStructure = FileOrFolder.new
newStructure.fullpath = path
pathbits = path.split('/')
newStructure.name = pathbits.last
newStructure.save
parentpath = path.sub(/#{Regexp.escape(pathbits.last)}$/, '')
if parentpath.length > 1
parentpath.sub!(/\/$/,'')
parent = FileOrFolder.find(:first, :conditions=>["fullpath = ?", parentpath])
unless parent
parent = FileOrFolder.import(parentpath)
end
#newStructure.move_to_child_of(parent);
**newStructure.find_or_create_by_path(parent);**
end
newStructure.save
return newStructure
end

I'm the author of closure_tree. 4.2.3 is on it's way with the fix for attr_accessible. I'm just waiting for Travis to finish testing it.
It looks like your whole import method could be replaced with this line:
# Assumes that path is a string that looks like this: "/usr/local/bin/ruby"
def import(path)
FileOrFolder.find_or_create_by_path(path.split("/"))
end
This assumes you have this FileOrFolder setup:
class FileOrFolder < ActiveRecord::Base
acts_as_tree
before_create :set_fullpath
def set_fullpath
if root?
self.fullpath = "/#{name}"
else
self.fullpath = "/#{parent.ancestry_path.join("/")}/#{name}"
end
end
end
Please take a look at the spec directory. You'll find tons of other examples.
