A simple script to upload OsmChange file #osm #changeset #script

README.md

Upload OsmChange file with script

Usage

# By default, changeset would be uploaded to test server: 
# https://master.apis.dev.openstreetmap.org
./osm.api.changeset.commit <OSC FILE>

# Use --serious to upload changeset to normal OSM server
./osm.api.changeset.commit --serious <OSC FILE>

# STDIN would be treated as comment, or a prompt shows up
echo "This is changeset comment" | ./osm.api.changeset.commit <OSC FILE>

# Set env OSM_USER_PASSWD as the following format, to skip prompt input:
# <USER>:<PASSWORD>
OSM_USER_PASSWD=<USER>:<PASSWORD> osm.api.changeset.commit <OSC FILE>

# Set env CHANGESET with the id of a open changeset
# Then script will not create a new changeset
# Instead, use existing one to upload OSC file and close it
CHANGESET=<ID_OF_CHANGESET> ./osm.api.changeset.commit <OSC FILE>

# Alternative way with online script
curl -fsS https://raw.githubusercontent.com/typebrook/helper/dev/bin/osm/osm.api.changeset.commit | \
bash /dev/stdin <OSC FILE>

# For development, use bats for testing:
# https://bats-core.readthedocs.io/

Okay. Then never mind the 'checkbashisms' script I was going to tell you about. Also curl has some --fail options you might take advantage of instead of examining the code manually.
As to the the /dev/tty stuff and -t ... just more asking for trouble.
case ... [0123456789]*[0123456789] esac could even check for valid changeset numbers... I'll leave the challenge of how to even check for one digit changeset numbers .... Anyway you would have the valid matches separated by a pipe and then you fail if it doesn't match any of them. I'm sorry I'm writing this on a cell phone otherwise I'd go in to more detail. Anyway even a shell from the '70s could work with that. I'm just saying like you see in the other user's comment... You never know what kind of shell simebody might have... it might even be a zsh. So there's no point making the whole script break. It's (or was) just such a short script. It should be just like one of those Debian system scripts that don't take any chances with the kid stuff.

Good to know this! I think I have heard this thing, now it is in my filesystem.

Also curl has some --fail options

This is just for case of no output, I think you mean --fail-with-body (Fail when status code >400)?
I think this is a good approach.

As to the the /dev/tty stuff and -t ... just more asking for trouble.

I prefer the workflow looks like sending a mail. User can make comment both by STDIN or terminal.

I use pattern check of bash in [[ ]] only because it is just there. If I need to do this in Bourne shell, I prefer grep.

I'm just saying like you see in the other user's comment... You never know what kind of shell simebody might have... it might even be a zsh.

Since shebang is marked as /bin/bash, I don't think it is a problem. @dy1owens 's issue is using bash v3. Check variable BASH_VERSION in script should be the solution.

It's (or was) just such a short script. It should be just like one of those Debian system scripts that don't take any chances with the kid stuff.

Okay...let me try if I can make it POSIX compatible. Should be a good practice for me.

@jidanni I think now it is POSIX compatible, bats is introduced for testing.
