From c222b08005a9a7e8e45bef8b074fd3ab12cd8a5f Mon Sep 17 00:00:00 2001 From: Kim Alvefur Date: Sun, 16 Jul 2023 21:21:37 +0200 Subject: util.human.io: Fix stray 'stty' error by only querying width of real ttys This adds a dependency on a binary and *nix-specific module but then stty is probably *nix-specific anyway so maybe that's fine. --- util/human/io.lua | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'util/human') diff --git a/util/human/io.lua b/util/human/io.lua index 542e4ceb..5af8d13e 100644 --- a/util/human/io.lua +++ b/util/human/io.lua @@ -1,4 +1,5 @@ local array = require "prosody.util.array"; +local pposix = require "prosody.util.pposix"; local utf8 = rawget(_G, "utf8") or require"prosody.util.encodings".utf8; local len = utf8.len or function(s) local _, count = s:gsub("[%z\001-\127\194-\253][\128-\191]*", ""); @@ -111,6 +112,9 @@ end local function term_width(default) local env_cols = tonumber(os.getenv "COLUMNS"); if env_cols then return env_cols; end + if not pposix.isatty(io.stdout) then + return default; + end local stty = io.popen("stty -a"); if not stty then return default; end local result = stty:read("*a"); -- cgit v1.2.3
