## Unreleased

### Changed
- Performance: the HTML report emits each page's code table in one awk pass and stops forking `cat` for every markup block — 9.5s to 4.5s for 128 files, and 58.7s to 4.5s together with the escaping fix (#1098)
- Performance: `--coverage-report-html` no longer forks twice per source line to escape it — 58.7s to 9.5s for 128 files here, with the escaping done once per file and the per-page `wc`, `basename` and `pwd` calls replaced by parameter expansions (#1096)
- Performance: the coverage report picks its colours without a subshell per file and per function — the text report over 128 files went from 387ms to 318ms, and 4042ms to 3116ms with `BASHUNIT_COVERAGE_SHOW_FUNCTIONS` on (#1092)

# HTML coverage report: the per-file page.

# The code table of one page, in one awk pass.
#
# The Bash loop that did this classified, looked up and echoed per source line:
# 8116ms for 128 pages over 22,405 lines, with no forks left in it -- Bash is
# simply the wrong tool for emitting 7MB of markup (#1098). Every input it
# needs is already a file: the aggregated hits, the per-line test list and the
# source itself.

# Composed with the classifier rules, which are included ahead of it.

## Unreleased

### Changed
- Performance: the HTML report emits each page's code table in one awk pass and stops forking `cat` for every markup block — 9.5s to 4.5s for 128 files, and 58.7s to 4.5s together with the escaping fix (#1098)
- Performance: `--coverage-report-html` no longer forks twice per source line to escape it — 58.7s to 9.5s for 128 files here, with the escaping done once per file and the per-page `wc`, `basename` and `pwd` calls replaced by parameter expansions (#1096)
- Performance: the coverage report picks its colours without a subshell per file and per function — the text report over 128 files went from 387ms to 318ms, and 4042ms to 3116ms with `BASHUNIT_COVERAGE_SHOW_FUNCTIONS` on (#1092)

## Unreleased

### Changed
- Performance: the HTML report emits each page's code table in one awk pass and stops forking `cat` for every markup block — 9.5s to 4.5s for 128 files, and 58.7s to 4.5s together with the escaping fix (#1098)
- Performance: `--coverage-report-html` no longer forks twice per source line to escape it — 58.7s to 9.5s for 128 files here, with the escaping done once per file and the per-page `wc`, `basename` and `pwd` calls replaced by parameter expansions (#1096)
- Performance: the coverage report picks its colours without a subshell per file and per function — the text report over 128 files went from 387ms to 318ms, and 4042ms to 3116ms with `BASHUNIT_COVERAGE_SHOW_FUNCTIONS` on (#1092)

## Unreleased

### Changed
- Performance: the HTML report emits each page's code table in one awk pass and stops forking `cat` for every markup block — 9.5s to 4.5s for 128 files, and 58.7s to 4.5s together with the escaping fix (#1098)
- Performance: `--coverage-report-html` no longer forks twice per source line to escape it — 58.7s to 9.5s for 128 files here, with the escaping done once per file and the per-page `wc`, `basename` and `pwd` calls replaced by parameter expansions (#1096)
- Performance: the coverage report picks its colours without a subshell per file and per function — the text report over 128 files went from 387ms to 318ms, and 4042ms to 3116ms with `BASHUNIT_COVERAGE_SHOW_FUNCTIONS` on (#1092)

# HTML coverage report: the per-file page.

# The code table of one page, in one awk pass.

# The Bash loop that did this classified, looked up and echoed per source line:
# 8116ms for 128 pages over 22,405 lines, with no forks left in it -- Bash is
# simply the wrong tool for emitting 7MB of markup (#1098). Every input it
# needs is already a file: the aggregated hits, the per-line test list and the
# source itself.

# Composed with the classifier rules, which are included ahead of it.

## Unreleased

### Changed
- Performance: the HTML report emits each page's code table in one awk pass and stops forking `cat` for every markup block — 9.5s to 4.5s for 128 files, and 58.7s to 4.5s together with the escaping fix (#1098)
- Performance: `--coverage-report-html` no longer forks twice per source line to escape it — 58.7s to 9.5s for 128 files here, with the escaping done once per file and the per-page `wc`, `basename` and `pwd` calls replaced by parameter expansions (#1096)
- Performance: the coverage report picks its colours without a subshell per file and per function — the text report over 128 files went from 387ms to 318ms, and 4042ms to 3116ms with `BASHUNIT_COVERAGE_SHOW_FUNCTIONS` on (#1092)

# HTML coverage report: the per-file page.

# The code table of one page, in one awk pass.
#
# The Bash loop that did this classified, looked up and echoed per source line:
# 8116ms for 128 pages over 22,405 lines, with no forks left in it -- Bash is
# simply the wrong tool for emitting 7MB of markup (#1098). Every input it
# needs is already a file: the aggregated hits, the per-line test list and the
# source itself.
#
# Composed with the classifier rules, which are included ahead of it.
