README

Description:

	FritzingCheckPart.py is a python script which checks parts files for
use by the Fritzing EDA program (fritzing.org). It started out to correct 
some of the issues that Fritzing has with the output from the Inkscape 
(inkscape.org) open source svg editor program. It then grew in to checking the
format of the various file (fzp and svg) that make up a fritzing part. 
	As a part of that it also prettyprints xml (with varying success), it 
does best with postprocessed fritzing svg files, because it understands their
format and has modified the xml (mostly moving CSS style commands in to inline
xml which as a side effect makes prettyprinting easier), to better suit 
fritzing. A standalone script PP.py, is included which will prettyprint a 
xml document without doing any of the fritzing related conversions.

Installation:

	The script uses python3 and the lxml library extensions to python.
Since Fritzing runs on Windows, linux and MacOS X the script should run on
those platforms too, and it may. I don't have MacOS X so I don't know that 
it will run there (although there is no reason that it shouldn't, I just
haven't done it.)

On Windows:

	I run the script from cygwin on Windows. It will likely run on one of
the native python implementations (you may need to use pip to install the lxml
extension) but I haven't done so. For cygwin you need to install cygwin 
(cygwin.org) using the setup program as detailed on cygwin.org. The basic 
install with the following additions does fine:

python3: Py3K language interpreter 
python3-lxml: Python XML2/XSLT bindings 

(and all their associated dependencies)

with that in place from a cygwin terminal copy the python scripts 

FritzingCheckPart.py
FritzingTools.py
PP.py
PPTools.py

to /usr/local/bin

chmod ugo+x /usr/local/bin/*.py

On Linux (Ubuntu 16.04 LTS):

copy the py scripts to /usr/local/bin via sudo:

sudo cp FritzingCheckPart.py /usr/local/bin 
sudo cp FritzingTools.py /usr/local/bin 
sudo cp PP.py /usr/local/bin 
sudo cp PPTools.py /usr/local/bin 

chmod ugo+x /usr/local/bin/*.py

The Ubuntu install appears to have lxml and python 3 already installed 

Note the script has problems with unicode under python 2.7 and probably won't
run there without modification (which I don't know how to make). 

Testing:

Assuming you have Fritzing installed the following will check (and complain
about!) the parts in core:

mkdir tst

FritzingCheckPart.py fritzing-0.9.3b.linux.AMD64/fritzing-parts/core tst

(replace the fritzing-0.9.3b.linux.AMD64/fritzing-parts/core with the path
 to your fritzing-parts core directory!)

which should produce output like this (in large volume) on the console:


**** Starting to process file 10x2-Epaper-Breakout-Board-v11.fzp


Error: File
'/cygdrive/c/fritzing/fritzing.0.9.3b.64.pc/fritzing.0.9.3b.64.pc/fritzing-parts/core/10x2-Epaper-Breakout-Board-v11.fzp'

Connector0 doesn't exist (connectors should start at 0)

...


Normal use:

PrettyPrinting:

PP.py xml_file [another_xml_file ...]

will pretty print the xml file to xml_file leaving the original file in 
xml_file.bak internally it sets the file type to svg so that it will split
blanks in lines such as attribute="value" attribute="value" in to 

attribute="value"
attribute="value"

with appropriate indenting. Since this is meant for post processed Fritzing 
svg file it may or may not do what you want. So try it and see. It won't 
split on blanks in text or quoted strings but may screw up on general xml 
sometimes, so use it if it is useful. 

FritzingCheckPart.py

There are several modes (selected internally by the number and type of 
the arguments to the script.):

1)

dir to dir:

FritzingCheckPart.py src_dir dst_dir

This processes all the fritzing files it finds in src_dir and writes their 
output in to dst_dir. Dst_dir needs to be empty to avoid damaging existing 
files. Subdirectories to match the fritzing file set up will be created in
the dst_dir. If you are processing part.fzp type files the output will go 
in to dst_dir at the top level and the svg and subdirectories will remain
empty. In the case of core in the example above the identical directory 
format will be recreated under dst_dir. To run this a second time you need
to empty the dst_dir via command like 

rm -R dst_dir/*

This is mostly used for testing (against core as a source of diverse files, 
many with errors) and to allow a mass correction of core if desired. Note 
you only want to run this mode against core as the other modes will change
files in core that are under git control and tend to break Fritzing. 

2)

FritzingCheckPart.py part.filename.fzp

part.filename.fzp format (from an unzipped .fzpz file which will have files
of the form 

part.filename.fzp
svg.breadboard.filename.svg
svg.icon.filename.svg
svg.schematic.filename.svg
svg.pcb.filename.svg

The input files will be renamed to filename.bak with the script output, the
fixed up (we hope) xml, written to the original file name ready to be rezipped
and loaded to fritzing. If something goes wrong, the original data is in the
.bak files (so long as you haven't run the script twice). First the fzp file
will be processed to get the connector information and the expected svg files,
then each svg file in turn will be processed. So you need to pay attention to 
the file name in the error messages, as it may not be referring to the input
file, but an svg file linked from the input file. 

3)

FritzingCheckPart.py parts/user/filename.fzp

the input file is in directory user/filename.fzp (and the user in the path 
is required to be present, the script will error out if it is not). The svg 
files are in 

user/svg/user/breadboard/filename.svg
user/svg/user/icon/filename.svg
user/svg/user/pcb/filename.svg
user/svg/user/schematic/filename.svg

which is the standard place where imported parts are stored by fritzing (in 
the core exampe at the start of this, the "core" directory is the same as 
"user" here). Again the fzp file will be processed followed by the associated
svgs. So again you need to pay attention to the file name in the error 
messages, as it may not be referring to the input file, but an svg file 
linked from the input file. 

4)

FritzingCheckPart.py filename.svg

this form does what checks it can on the svg file (which aren't that many as 
it lacks the data from the fzp file to know what connectors it should be 
checking for). What it does do is the original purpose of this script which
is to change the style(attribute:value;attirbute:value) commands to the 
equivelent inline xml attirbute="value" attribute="value" as parts 
of fritzing, (specifically bendable legs) don't support style type attributes 
and won't work if they are present. It changes font-size=3.5px to 
font-size=3.5 as the trailing px, required by CSS, causes font size errors 
in fritzing. It converts silkscreen (in pcb) items from the old standard 
white (which Inkscape with a white background won't display succcessfully) to
the new standard of black. It will discover and complain about (but not so
far, do anything about, due to positioning/scaling issues) terminals that 
have a zero height or width. These are not selectable by Inkscape making 
them difficult to move in the svg. Unfortunatly you need to manually change 
the size (which changes the position) and then move the teriminal to the 
correct position. It would be nice to automate this, but it isn't done now.
Last but not least, if this is a pcb svg file it moves stroke-width
commands which would be inherited by a lower level group in to that group. 
The scripts that produce gerber files are not able to access inherited values 
(as they aren't reading the xml) and thus if a stroke-width would be 
inherited from a higher level and thus is not present at the level the pad 
is generated at gerber production fails. I expect this will be the main use 
for this script. After modifiying a svg file with Inkscape you need to run 
this script to correct the modifications that Inkscape has made for CSS 
compliance before feeding it to Fritzing (which isn't CSS compliant in at 
least some cases). 

Configuration:

There are four internal configuration settings (you need to edit the listed
.py file and change these with a text editor):

1) in file PPTools.py

DetailPP = 'y'

Enabled by default. If detail prettyprinting of an svg appears to have screwed
up, set this value to 'n' to disable detail prettyprinting and try again. If it
works without the detailed prettyprinting please file a bug.

2) in file FritzingTools.py

ModifyTerminal = 'n'

Disabled by default because it will make a change that will change the spacing
of the terminal position in the svg, which you will manually need to correct 
using an svg editor, if the width or height is 0. I enable this (by setting the
value to 'y') and then pay attention to the modifed messages to tell when it
has changed a terminal from 0. If the terminal is 0 width or height at least
Inkscape (which I use) will not select the element to move it. You have to
manually select the element and change its position with the tool bar which
I find annoying. With the value set to 'n (the default) you will get a warning
message like this one from a current core part:

Warning 16: File
'/cygdrive/c/fritzing/fritzing.0.9.3b.64.pc/fritzing-parts/core/../svg/core/schematic/4071_4_x_2_input_OR_gate_multipart_schematic.svg'
At line 66

Connector connector6terminal has a zero height
and thus is not selectable in Inkscape

This warning is all that it will do. It is up to you to edit the svg and set 
the height/width to something other than 0 and correct the x/y positioning. 

	With the value set to 'y' on the same file (in this case changed to an
exported part so as to not change core which will break parts update, but the 
same file as above) there is a different message in a different place:

Modified 2: File
'svg.schematic.prefix0000_fa1ebd566edf2f3d943a0046711f2d3c_1_schematic.svg'
At line 23

Connector connector6terminal had a zero height, set to 10
Check the alignment of this pin in the svg!

This message tells you the script has made a change that is going to have moved
the x/y position of the connector (and depending on what the scaling in the svg
is set to, perhaps made the height/width incorrect, as 10 isn't an appropiate 
value for all scale factors). The warning message is no longer present as there
is now this change notification instead. As a result you need to edit the svg 
and check that the terminal is 10 thou (or your preferred size, 10 thou is 
mine) and in the correct x/y position as expected by the part. The upside is 
that Inkscape will now select the terminal and move it if you move the entire 
terminal which it wouldn't before. 

3) in file FritzingCheckPart.py

IssueNameDupWarning = 'y'

This value (enabled by default) if set to 'n' will supress the Warning 28:
message which indictes the name field is not unique. While it should be 
unique according to the parts file format document, Fritzing doesn't appear
to care and it seems to be only used for display in pin labels when hovered
over. It is fairly common to not be unique and thus clutters up the error
message display. I usually set this to 'n'.

4) in file FritzingCheckPart.py

Debug = 0

This value enables debug messages (set to 1 for file output to the console
but no further debug messages, set to 2 for enter/exit routine debug messages,
and to 3 for detailied but very verbose debug messages). It is used for 
debugging the script itself so you will normally leave it at 0 for normal 
operation. 



Likely bugs:

The most likely bug relates to prettyprinting. To prettyprint svg files the
lines are split on blanks (' ') and each element is indented and printed on 
a new line. Obviously (and for text, comments and referenceFile names so far,
detected and corrected for) lines with spaces that are supposed to be there
in the final document will get screwed up by the above and will need their 
tags added to the exemption regex in the code. 
	The original file(s) are saved in a .bak file (i.e. filename.svg will
be moved to filename.svg.bak with the script output in filename.svg). However
if you run the script a second time without copying the .bak file somewhere 
safe the original file will be overwritten without further warning, so be 
careful. In case of script error you will likely want the original file ...
	There also may be any number of other bugs I haven't found yet. If you
come across one please report it and I'll see if I can fix it.  

Known bugs:

1) Makeing a square pad in pcb via a path with a hole in it usually (but
   apparantly not always) works in Fritzing. This script however will toss

Error 74: File
'/cygdrive/c/fritzing/fritzing.0.9.3b.64.pc/fritzing-parts/core/../svg/core/pcb/DRV8825_breakout_pcb.svg'
At line 17

Connector connector136 has no radius no hole will be generated

   Which isn't correct (but also isn't easy to fix). You can either ignore this
   error as invalid (as long as the gerber export works which it does in this
   case) or replace the pad with a standard circle with a radius and stroke 
   width (which would be my choice in the matter!) which will remove this error.


Potential error messages and what to do about them:

First the dreaded trace back:

$ ./FritzingCheckPart.py Bean_revE.fzp
Traceback (most recent call last):
  File "./FritzingCheckPart.py", line 51, in <module>
    rc, FileType, Path, File = tools.ProcessArgs (sys.argv, Errors)
TypeError: 'int' object is not iterable

if you get a message like this, then I have screwed up and offended the python
gods and they have taken exception (this is basically a software error). The
best bet is to provide the call above and if possible a copy of the file that
caused it so I can try and fix it. 



now on to expected error messages:

Most (but not all, as the first few below show) error messages are of the 
form:

Error: File
'/cygdrive/c/fritzing/fritzing.0.9.3b.64.pc/fritzing.0.9.3b.64.pc/fritzing-parts/core/blend_micro1.0.fzp'
At line 444

which gives you the file name followed by the line number (if known, sometimes
it isn't) of where the error was detectd. 

	Of note is the filename will be blend_micro1.0.fzp.bak if you are 
processing an individual part (which will normally be the case). The reason 
for this is the output file 

blend_micro1.0.fzp

has been prettyprinted, and the line numbers won't match the input file 
(blend_micro1.0.fzp.bak) so you need to look for the error in the filename 
listed in the error message and then match it to the same text (which will 
have a different line number and possibly format very likely) in the output 
file if you need to. The input file will give you the place in the file that 
the error occurred and you should fix it there and then remove the .bak 
extension and re run the script in the corrected input file. 

Usage messages (which are a type of error as they are fatal, but don't have
numbers any more)


Usage: PP.py filename (filename ...)

	Indicates you didn't give a filename to the PP.py script. It wants 
	one or more xml files such as

	PP.py test.svg 

	or 

	PP.py test1.svg test2.xml test3.fzp


Usage: FritzingTools.py filename.fzp or filename.svg or srcdir dstdir

	Either no or too many arguments to the script. It wants either a 
	single file name or 2 directories. 


Usage: FritzingTools.py src_dir dst_dir

src_dir filename isn\'t a directory

	In this mode both arguments need to be directories and src isn't. 


Usage: FritzingTools.py src_dir dst_dir

dst_dir filename isn\'t a directory

	In this mode both arguments need to be directories and dst isn't. 



Error messages in the order they occur in the code so essentially random
but numbered so you can index by the number to get the error description
and an explaination of the errror (with the move of the Usage messages
above, some numbers are now missing though.)  


Error 1: Can not rename filename os_error_message (os_error_number)

	The os routines returned an exception when the input file was 
        renamed. Hopefully the cause is obvious from the os messages. 


Error 2: Can not open filename  os_error_message (os_error_number)

	The os routines returned an exception when the input file was 
        opened. Hopefully the cause is obvious from the os messages. 


Error 3: Can not write filename  os_error_message (os_error_number)

	The os routines returned an exception when the input file was 
        written. Hopefully the cause is obvious from the os messages. 


Error 4: Can not close filename os_error_message (os_error_number) 

	The os routines returned an exception when the input file was 
        closed. Hopefully the cause is obvious from the os messages. 


Error 5: ParseFile can't read file filename

	The xml parser got an I/O error trying to parse the named file.


Error 6: ParseFile error parsing the input xml file filename

	The xml parser found illegal xml at the line and column listed after
	this. Note the lxml parser is more strict than either Inkscape or 
	Fritzing and will report errors that both Inkscape and Fritzing 
	will accept as valid xml. If you look however, there really is an 
	error there and you should correct it. Below is an example from the 
	Bean_revE.fzp file currently in core:

	/cygdrive/c/fritzing/fritzing.0.9.3b.64.pc/fritzing.0.9.3b.64.pc/fritzing-parts/core/Bean_revE.fzp:161:90:FATAL:PARSER:ERR_SPACE_REQUIRED: attributes construct error
 
	line 161 from Bean_revE.fzp

	<p layer='schematic' hybrid='yes' svgId='connector81pin' terminalId='connector81terminal'hybrid='yes' /></schematicView>

	there are two errors in this line. There is a missing space between 
	connector81terminal' and hybrid='yes' and the second hybrid='yes is 
	wrong. The line should be corrected to this:

	<p layer='schematic' hybrid='yes' svgId='connector81pin' terminalId='connector81terminal' /></schematicView>

	which is correct xml and the complaints from parser will stop. You 
	will get a lot more errors, but again they are really there, even 
	though the part with these errors loads and runs happily in Fritzing. 


Error 8: filename isn't a file: ignored

	The file name provided either isn't a file or isn't readable and has
	been ignored. 


Error 10: There must be a directory that is not '.' or '..' in the input name 
for a fzp file in order to find the svg files.

	Indicates that it needs a directory (for example core/file.fzp) in
	order to figure out where the svg files are (../svg/core/... in this
	case). Supply the directory and it will be happy. 


Error 13: dst dir

dst_dir

must be empty and it is not

	The dst_dir isn't empty (perhaps from a previous run). If you are sure
	the directory is expendable rm -R dst_dir/* will fix this.


Error 14: Creating dir

dir_name  os_error_message (os_error_number)

	A problem creating one of the dst directories. Hopefully the os error
	messages will make the cause clear. 


Error 15: Can not rename

'src_file'

to

'src_file.bak'

'file_name_from_os'

os_error_message (os_error_number)

	A problem occurred trying to rename the src_file to src_file.bak.
	Hopefully the os error messages indicate why. 


Error 16: File
'filename'
At line 20

Id xxx present more than once (and should be unique) 

	The listed id is present more than once and should be unique (often
	Fritzing ignores this but it is incorrect) 


Error 17: File
'filename'

No connectors found for view viewname.

	This is one of those messages without a line number as after all the
	connectors have been processed, no connectors were found. 


Error 18: File
'filename'

Connector connector2terminal is in the fzp file but not the svg file. (typo?)

	This connector is specified in the fzp file, but isn't in the 
	associated svg file. Depending on what type of connector it is
	this may or may not be fatal (a svgId is fatal a terminalId is not).
	In either case it is incorrect.


Error 19: File
'filename'

File type xxx is an unknown format (software error)


	Another case of software error where the type isn't svg, fzppart or
	fzpfritz. Shouldn't happen.


Error 20: File
'filename.svg'

During processing svgs from fzp, svg file doesn't exist 

	The filename referenced for this view in the fzp file doesn't exist. 
	Fritzing will try and find something to substitute, but this is still
	an error. 


Error 21: Svg file

'Filename.svg'

Has a different case in the file system than in the fpz file

'filename.svg'

	This doesn't matter on Windows as the file system is case insensitive
	however it does matter on Linux and probably MacOS where the file
	system is case sensitive and the wrong case file will not be found. 
	Change either the fzp or the file in the file system to the same 
	case and all will be well on all systems. While I could correct this
	in the fzp file it seems better to do it manually because it isn't 
	clear whether the fzp file is incorrect or this particular file system
	is incorrect, and thus is better left to a human decision rather than
	a program.


Error 22: File
'filename.fzp'
At line 1

No ModuleId found in fzp file

	There isn't a moduleId in the fzp file. This is likely fatal as I don't
	think the part can load without a moduleId. Add a moduleId to the file
	(preferably export a new part to get a Fritzing approved moduleId).


Error 23: File
'filename.fzp'
At line 20

	A non empty Bus definition has already been seen. Fritzing won't 
	currently support both busess and schematic parts.

State error, expected tag tag not a view name

	There is something wrong in the fzp file (or this code). The tag we
	have doesn't match the expected state of a correct fzp file. Best bet 
	is to check the format of the fzp file against a known good version, 
	as there is probably an extra or missing line in this file. 


Error 27: File

	Didn't find any of iconView breadboardView schematicView or pcbView
	in the list of view names.


Error 37: File
'filename.fzp'

This is a smd part as only the copper0 view is present but it is on the 
bottom layer, not the top. If you wanted a smd part change copper0 to 
copper 1 at line 20 If you wanted a through hole part add the copper1
definition after line 19

	This is a smd part but it is on the wrong layer (and thus likely an
	error). If you really want the part to be on the bottom for something
	this error can be ignored.


Error 38: File

Connector connector1pad is an ellipse not a circle, (gerber generation will

	This indicates a connector in a pcb svg is an ellipse (i.e. has rx and

terminalId missing in schematicView (likely an error)

	There isn't a terminalId in the schematic connector definition. This

Connector connector1pin has a zero height or width
and thus is not selectable in Inkscape

	While connectors with 0 height or width work just fine, at least in 
	Inkscape they are not selectable by dragging a box around them and
	clicking on them. Thus you can't easily move them (you need to change
	their coordinates in the tool bar after selecting them in xml editor). 
	I prefer to use .01in by .01in rectangles for terminals because they 
	will select and move when selected with a dragged square in the gui. 
	Unfortunatly changing the height and width also changes the x/y
	position, so automatically correcting this will be more complex than
	just adding a value, so it is left for you to do at the moment. 

Warning 17: File

	there is no height attribute in the viewbox definition.


Warning 19: File
'filename.fzp'
At line 20

Height 200px is defined in px
in or mm is a better option (px can cause scaling problems!)

	While this is perfectly legal, it is unwise (but common!). If defined
	in px (and either no units or an explicit px is in px) fritzing will
	make a guess (and sometimes get it wrong) about how many px per inch
	the drawing used. Older Inkscapes (0.91 and older) used 90px per inch
	as of 0.92 they use the CSS standard of 96px per inch. Older copies 
	of Illustrator used 72px per inch. If you change this to being inches 
	or millimeters there is no guess required and it will scale correctly. 
	To do so in Inkscape do a edit select all and set the tool bar to in 
	or mm. Take the height and width (inches or mm) from the tool bar read 
	out and use xml editor to set those numbers in to the height and width 
	in the viewbox setting (with the in at the end to indicate this is in 
	inches). When you set them Inkscape will change the drawing to match 
	the new scale (note it is possible some part of the drawing may not 
	change correctly so visually check it). This is usually the cause of 
	a drawing that looks correct in Inkscape but is the wrong scale (i.e. 
	doesn't match the grid) in fritzing. To correct that, in Inkscape 
	you can recalculate the scaling like this: 
	
		heightpx * 72/90/96 = size in inches. 

	You will need to try the likely values 72, 90 or 96 til the scaling 
	in Fritzing is correct and then set the correct value in inches (or
	mm if you prefer) as the height and width in the first entry in xml 
	editor.

	is processed again in case there are errors relative to this fzp file
	that are different than the first processing instance. Because
