d.title with d.text does not insert title

[micha]

When using d.title combined directly with d.text, no title appears on the map display. The d.title flag -d does not create the tmp file with title text, and piping the output of d.title into d.text does not create any title.

i.e.:

GRASS 7.4.0 (WGS84):~ > d.title -d map=srtm_negev_3arc color=red     #
GRASS 7.4.0 (WGS84):~ > ERROR: Failed to run command 'd.text
input=/home/micha/GIS/grass/WGS84/PERMANENT/.tmp/TP480/11266.0
        at=50,50'. Details:

        GRASS_INFO_ERROR(11330,1): Unable to open input file
</home/micha/GIS/grass/WGS84/PERMANENT/.tmp/TP480/11266.0>
        GRASS_INFO_END(11330,1)

or

GRASS 7.4.0 (WGS84):~ > d.title map=srtm_negev_3arc color=red size=10 |
d.text align=cc
GRASS 7.4.0 (WGS84):~ >             # No error but NO title appears

The only option that works is to redirect d.title into a text file, then run d.text:

GRASS 7.4.0 (WGS84):~ > d.title map=srtm_negev_3arc > my_title2.txt
GRASS 7.4.0 (WGS84):~ > d.text input=my_title2.txt color=red at=75,75
# Text appears as expected

Can you try

d.title map=srtm_negev_3arc color=red size=10 |
 d.text align=cc input=-

? I'm on mobile and cannot test at time

[micha]

No difference on my setup. Using input=- does not give any error, but No title on the map display.

What works is redirecting d.title into a text file, then pointing to that file with d.text input=...

There are two problems:

1. d.title spawns d.text, but its input file gets deleted. d.text only creates a temp file for input=-, but not when a file is given. Please check r73883.

2. d.text input=- doesn't work. Looking into it.

[hcho]

One more problem:

d.mon start=wx0
d.text input=file

in one directory and change to another directory that has a different "file" and run

d.erase
d.text input=file

The monitor always picks up the file in the same directory where it got started.

I think this problem is GRASS_RENDER_IMMEDIATE vs. delegated rendering by render.py, but display modules should not care which renderer is being used.

[hcho]

For d.text input=-, please check r73884.

The last problem can be fixed by always creating a temporary file just like for stdin, but other display modules may have the same issue.

Ticket retargeted after milestone closed

Checked on 7.6, the prob persists.
