Allow spaces in image array filenames #1493

Sorry, I don't think that's possible at the libvips CLI right now. You'll need to use something like Python. Let's leave this issue open as an enhancement. |
|
(something like python, php, ruby, etc. should give you much better performance and IO behaviour too, so it might be worth investigating anyway) |
|
I`ll try out ruby-vips. |
|
Supporting \ as an escape character in strings should be simple. It's just this function: https://github.com/libvips/libvips/blob/master/libvips/iofuncs/type.c#L1292 |
|
Similar problem I`ve experienced when I wanted to use vips write_to_file. But ruby-vips worked as intended, I achieved solution |

/* compile with:
* gcc try305.c -g -Wall `pkg-config vips --cflags --libs`
*/
#include <vips/vips.h>
#define SIZE (100)
int
main( int argc, char **argv )
{
VipsImage *image;
int x, y, z;
VipsPel *mem;
if( VIPS_INIT( argv[0] ) )
vips_error_exit( NULL );
/* SIZE x SIZE rgba image.
*/
if( !(mem = VIPS_ARRAY( NULL, 4 * SIZE * SIZE, VipsPel )) )
vips_error_exit( NULL );
for( y = 0; y < SIZE; y++ )
for( x = 0; x < SIZE; x++ )
for( z = 0; z < 4; z++ )
mem[y * 4 * SIZE + x * 4 + z] = 2 * (x + y + z);
/* Wrap up as a 4-band VipsImage.
*/
if( !(image = vips_image_new_from_memory( mem, 4 * SIZE * SIZE,
SIZE, SIZE, 4, VIPS_FORMAT_UCHAR )) )
vips_error_exit( NULL );
if( vips_image_write_to_file( image,
"this is a filename with spaces.png", NULL ) )
vips_error_exit( NULL );
g_object_unref( image );
g_free( mem );
return( 0 );
}I see: |

Yes, that's the case. |
So: vips_break_token( "hello\ world", " " ) Sees a single token, `"hello world"`. This means you can now do things like: $ vips arrayjoin "k\ 2.jpg" x.png Where "k 2.jpg" is a filename containing a space. See #1493
|
OK, this works now: Where Sets a profile from a file called Thanks for the suggestion! |
|
Very useful. Thanks for update. |
|
And on windows where the backslash itself is a directory seperator, how to differentiate it in the path? |
|
You can use a double backslash, eg.: |
|
Hi, i'm failing to get a simple test file with a space to be found by vips... etc |
|
What's the exact command you are trying to run? I see: |
|
powershell: cmd: I right clicked on the file itself to confirm its existence -> copy path, and it gives the path: "D:\temp\BKLXSC 1696099971.tiff"
|
|
I tried in psh as well, it all seems to work here: |
|
I tried with tiffs and drive letters and that works too: |
|
There are two different ways of quoting backslash and space because there are two different things interpreting them. In plain command-line arguments, just use space and put the whole thing in quotes. PSH doesn't use backslash as escape, so you don't need to quote it:
I agree, it's confusing :( If you use something like python, all this shell craziness goes away. |
|
I came right, your examples helped, I was doing everything except the right thing, embarrassed |
I am trying to composite few images, but I need to use paths with spaces. How Can I escape them to use with vips command line?
Standard shell space escaping is not working.
vips composite "backgrounds\ additional/top.png backgrounds\ additional/bottom.png central.png" out.png 2 --x "3 10" --y "1 20"This command is not working either, because vips splits array by spaces.
vips composite "backgrounds additional/top.png backgrounds additional/bottom.png central.png" out.png 2 --x "3 10" --y "1 20"This command is not working, becuase ' is used explicitly
vips composite "'backgrounds additional/top.png' 'backgrounds additional/bottom.png' central.png" out.png 2 --x "3 10" --y "1 20"The text was updated successfully, but these errors were encountered:
