tablerow in templates truncates strings

[NickVolynkin]

Describe the bug

A clear and concise description of what the bug is. Include version by typing gh --version.

I have this code that makes a table of repo's issues:

start_timestamp=$(gdate --date="$(gdate +'%Y-%m-%d') - 1 month" +'%Y-%m-%d')
echo "Looking for issues closed since $start_timestamp -> closed.log"
gh issue list --search "is:closed closed:>$start_timestamp" --json 'title,url' \
  --template '{{range .}}{{tablerow .title .url}}{{end}}' > closed.log

(Here gdate is the GNU implementation of date from the coreutils package)

Just a month ago it used to make a table with full titles and URLs. But now gh truncates the strings, making the output basically useless:

Docs: table of content and language ...  https://github.com/tarantool/taranto...
Make separate customer zone pages fo...  https://github.com/tarantool/taranto...

I haven't found a way to revert to the previous behaviour in the following docs:

• https://cli.github.com/manual/gh_help_formatting
• https://docs.github.com/en/search-github/searching-on-github/searching-issues-and-pull-requests

gh version:

gh version 2.17.0 (2022-10-04)

Steps to reproduce the behavior

1. Run the code above on a repository with at least a few closed issues.
2. View the output in closed.log
3. See the title and URL strings truncated.

Expected vs actual behavior

Same but in 3. you get full titles and URLs.

Logs

To alleviate the problem, you could experiment with --jq or an environment variable.

1. --jq

gh issue list --search "is:closed closed:>$start_timestamp" --json 'title,url' --jq '.[] | .title + "\t" + .url' > closed.log

2. Environment Variable

GH_FORCE_TTY=100% gh issue list --search "is:closed closed:>$start_timestamp" --json 'title,url' \
  --template '{{range .}}{{tablerow .title .url}}{{end}}' > closed.log

EDIT:
3. printf

gh issue list --search "is:closed closed:>$start_timestamp" --json 'title,url' --template '{{range .}}{{ printf "%s\t%s\n" .title .url}}{{end}}' > closed.log

Thanks @NickVolynkin for reporting and @LangLangBart for tracking down. This is indeed a bug from #6084 and will be fixed by #6421.

Note that tablerow will still truncate table columns to make the whole table fit in the current terminal viewport. The bug is that the terminal width was incorrectly measured when stdout was redirected. But, with tablerow you are never safe from truncation. If you don't want truncation, you might want to avoid using tablerow and just output values directly.

The workaround to avoid truncation is to force a really wide terminal with GH_FORCE_TTY=10000
