All names of models & parts converted to CAPITALIZED LETTERS inside saved files (*.ldr, *.dat, *.mpd) about leocad

[leozide]

I've been meaning to do something about this for a while but was never high priority. Where did you see that names are case sensitive?

From http://www.ldraw.org/article/512 :

"While both upper and lower case letters are permitted in filenames, filenames are case-insensitive"

Where did you see that names are case sensitive?

I detect this thing when tryed import in Blender (using "ImportLDraw" addon) .mpd/.ldr produced by LeoCAD.

ImportLDraw addon is case sensitive, so can't import such files:

• LeoCAD output (UPPERCASED names of parts & models, but 0 FILE strings case-sensitive)

Inside LDraw library all names of .dat files inside ../ldraw/parts/ folder include only lowercase letters, but inside all ../ldraw/models/Note*.txt files there is mix of lower- & uppercase parts names (*.DAT mixed with .dat)

According all above I created two issues:

• for LeoCAD - keep case sensitive names of parts & models inside saved files (optional);
• for ImportLDraw - add option to ignore case sensitive naming of parts & models inside imported files (critical).

From http://www.ldraw.org/article/512

File Name

Filenames must not be longer than 25 characters (including the extension) and must only contain the following characters: a-z, A-Z, 0-9, _, and - (to avoid confusion with English grammar, comma is not a permitted character). While both upper and lower case letters are permitted in filenames, filenames are case-insensitive. Currently, all official parts are issued with upper-case only names.

Extension

All files in the LDraw Parts Library are required to carry the .DAT extension.

According this (space) not allowed in names of models (LeoCAD now allow "spaces" and non-latin letters, so this is issue and must be fixed)

For the parts naming .DAT look like correct (this is issue only for ImportLDraw).

According this (space) not allowed in names of models (LeoCAD now allow "spaces" and non-latin letters, so this is issue and must be fixed)

That's for file names in the library, not model names in MPDs or model file names.

model names in MPDs or model file names.

Partly, yes. I just tested ImportLDraw for import exported from LeoCAD single-model '.ldr' and its work well (there is some viewpoint issue, but its not related to naming)

But when try import in Blender multi-parts '.mpd', exported from LeoCAD, ImportLDraw read submodels...

0 FILE Sabah FreeStyle promotional set #1779.mpd
1 16 0 0 0 1 0 0 0 1 0 0 0 1 HELICOPTER #1779-1.LDR

... and expect that there is 0 FILE HELICOPTER #1779.LDR, but in exported from LeoCAD '.mpd' this entry case-sensitive

0 FILE Helicopter #1779-1.ldr

So, need test '.mpd' files produced by LeoCAD in other CAD's that support LDraw.

If this is issue only for ImportLDraw, then as workaround need allow ImportLDraw ignore case-sensitive naming on multi-parts documents import.

P.S.: As for me, it would be much better add restriction that inside '.mpd' format all letters must be ONLY UPPERCASED + not allow use "spaces" in submodels naming - use only A-Z, 0-9, _, -, . and (if needed) ,.

If need add "space" in submodels we must use _, because use of "space" in CSV-like documents ('.dat', '.ldr', '.mpd', etc.) is bad thing, especially for parsing those files.

@leozide, I tested latest version from OBS for case size fix that you made few days ago.

It still has issue in output files

If LDraw part has filename 2635c23.dat, then now in output file it writed as 2635C23.dat.

So, for now (comparing to 17.07 release) LeoCAD use same case size in part extensions text, but in name before extension text it still use UPPERCASE for all leters.

That change fixed a different bug.
