For Linux

[Miscni]

Any chance, for a proper guide, on how to set it up on Linux?

Because some of the information, seems to be missing some stuff.

I used this project as a template and was able to get it to work successfully using a SmartSVN Server installation on a CentOS 7 Linux server

The post-commit file should have this in the bottom:

REPOS="$1"
REV="$2"
TXN_NAME="$3"
WEBHOOK_URL="YOUR WEBHOOK URL HERE"
WEBHOOK_PATH="/<YOUR REPO DIRECTORY>/hooks/discordSend.py"
PYTHON_PATH="/usr/bin/python3.6"
LOCATION="trunk"

# Filter all commits so the webhook only sends messages when Trunk is committed to. If you want it to notify ALL SVN commits, then delete the whole IF statement below
if /opt/CollabNet_Subversion/bin/svnlook changed $REPOS -r $REV | grep -i trunk
then
	$PYTHON_PATH $WEBHOOK_PATH "$REV" "$REPOS" "$WEBHOOK_URL" "$LOCATION"
	exit 1
fi
exit 0

Here is my modified implementation of the discordSend.py file:

# Import libraries for HTTP requests, processing EXE output, and getting parameter values passed from our caller script (in VisualSVN)
import requests
import subprocess
import sys
import os.path

# Discord has a message length limit of 2000 characters, so we need to set some maximum string length limits
MAX_LENGTH_LOG = 200
MAX_LENGTH_CHANGELIST = 1700

# Base name to give our bot that'll post the payload message
botusernamebase = "SVN"

# URL of image to use for our bot's avatar (I recommend hosting this image elsewhere like AWS)
botavatarurl = "https://upload.wikimedia.org/wikipedia/commons/thumb/f/f4/Antu_smartsvn.svg/1200px-Antu_smartsvn.svg.png"

# Root directory in which the repositories are stored
reporootdir = "/svn/data/repositories/"    # CHANGE THIS TO POINT TO YOUR REPOSITORY ROOT DIRECTORY

# Local file path of svnlook.exe, which is used to get the commit's author, log, and changelist
svnlook = "/opt/CollabNet_Subversion/bin/svnlook"    # CHANGE THIS TO POINT TO YOUR SVNLOOK.EXE PATH

# URL of webhook to which we'll send our payload
webhookurl = sys.argv[3]

# Revision number of the commit
revision = sys.argv[1]

# Name of the repository that was committed to
reponame = os.path.basename(sys.argv[2])

# Name of the location that was committed to
location = sys.argv[4]

# Assemble the repository's file path
repopath = "{0}{1}".format(reporootdir, reponame)

# Get the commit's author with svnlook
process_author = subprocess.Popen([svnlook, "author", repopath, "-r", revision], stdout=subprocess.PIPE)
author, author_err = process_author.communicate()

process_log = subprocess.Popen([svnlook, "log", repopath, "-r", revision], stdout=subprocess.PIPE)
loglong, loglong_err = process_log.communicate()

# Set default message for when there's no commit message
if loglong.decode().isspace():
	log_decoded = True
	loglong = "<no commit message>"
else:
	log_decoded = False

# Get the commit's changelist with svnlook
# process_changelist = subprocess.Popen([svnlook, "changed", repopath, "-r", revision], stdout=subprocess.PIPE)

# Set default message for when there's (somehow) no changelist
# if changelistlong.decode().isspace():

#	changelistlong = "<no changelist>"
#else:

# Prune the new lines from the endings
author = author.strip()
loglong = loglong.strip()
# changelistlong = changelistlong.strip()


# Truncate end of log if it exceeds max length
if (len(loglong) > (MAX_LENGTH_LOG - 6)):
	log_decoded = True
	logparsed = loglong[0:(MAX_LENGTH_LOG - 6)]
	log = "{0} <...>".format(logparsed.decode())
else:
	log = loglong

# Truncate end of changelist if it exceeds max length
#if (len(changelistlong) > (MAX_LENGTH_CHANGELIST - 6)):
#	changelist_decoded = True
#	changelistparsed = changelistlong[0:(MAX_LENGTH_CHANGELIST - 6)]
#	changelist = "{0} <...>".format(changelistparsed.decode())
#else:
#	changelist = changelistlong


# Do some last-minute pruning for good measure
reponame = reponame.strip()
revision = revision.strip()
author = author.decode()

# Decode the log and changelist if they haven't been already
if not log_decoded:
	log = log.decode()
#if not changelist_decoded:
#	changelist = changelist.decode()


# Assemble our bot's username based on the base name and the author who made the commit (e.g., "Aaron (Subversion)")
botusername = "{0} ({1})".format(author, botusernamebase)

# Assemble our message to include in the payload
message = "**{0}:**  Revision {1} committed to {4} by {2}:\n```{3}```".format(reponame, revision, author, log, location)

# Construct our payload to send to the webhook
payload = {
	'username': botusername,
	'avatar_url': botavatarurl,
	'content': message
}

# Send our payload to the webhook with an HTTP POST request
r = requests.post(webhookurl, data=payload)
print(r.status_code, r.reason)
