# Script para actualizar librerías automáticamente
- 0 notificaciones de `shellcheck` en modo `POSIX sh`
- Solamente comandos estrictamente necesarios y utilidades/funciones de `POSIX sh (printf, while, case)`
## 1. Revisar comandos externos a shell, definir funciones para loggear
```sh
#!/bin/sh
# External dependencies:
deps="curl tar cd mkdir cmake make"
script_name="$0"
success() {
printf ' %s - \033[32mSuccess:\033[0m \033[2m%s\033[0m\n' "$script_name" "$1"
}
warn() {
printf ' %s - \033[33mWarn:\033[0m \033[2m%s\033[0m\n' "$script_name" "$1"
}
consolelog() {
printf ' %s - \033[2mLog: %s\033[0m\n' "$script_name" "$1"
}
error() {
printf ' %s - \033[31mError: %s\033[0m\n' "$script_name" "$1"
}
missing_deps="$(for dep in $deps ; do
! command -v "$dep" 1>/dev/null 2>&1 && printf '%s ' "$dep"
done)"
[ -n "$missing_deps" ] && error "Missing dependencies for $script_name: $missing_deps" && exit 1
...
```
## 2. Función para comprobar la última versión de wxWidgets
```sh
get_latest_wx() {
url="https://api.github.com/repos/wxWidgets/wxWidgets/releases/latest"
current_wx="$(for wx in lib/wx/wxWidgets-* ; do printf '%s' "$wx" ; done)"
current_wx="${current_wx##*-}"
current_wx="${current_wx%.tar.bz2}"
latest_wx_url="$(curl -s "$url" | while IFS= read -r line ; do
case "$line" in *browser_download_url*)
url="${line%\"*}" ; url="${url##*\"}" ; file="${url##*/}"
[ "${file##*.}" = "bz2" ] && [ "${file%-*}" = "wxWidgets" ] &&
printf '%s\n' "$url" && break ;;
esac
done)"
mkdir -p lib/wx
file="${latest_wx_url##*/}"
latest_wx_dir="lib/wx/${file%%.tar.bz2}"
latest_wx="${latest_wx_dir##*-}"
# Nor file nor new version can be determined
[ -z "$file" ] || [ -z "$latest_wx" ] && return 1
# wx is up to date, 0 if success
[ "$latest_wx" = "$current_wx" ] &&
success "wxWidgets-$current_wx is the latest version" &&
return 0
...
```
## ... o descargarla de lo contrario
```sh
# Download wx if not present or outdated, 0 if success 1 if fail
warn "wxWidgets-$current_wx is behind wxWidgets-$latest_wx, downloading..."
curl -sLO "$latest_wx_url" &&
curl -sL "$latest_wx_url" -o "lib/wx/$file" &&
consolelog "Extracting $file..." && (cd lib/wx && tar xf "$file") &&
consolelog "Deleting archive $file..." && rm -f "lib/wx/$file" &&
return 0 || return 1
}
...
```
## 3. Función para construir wx-config
```sh
build_wx() {
mkdir -p "$latest_wx_dir/autobuild"
(cd "$latest_wx_dir/autobuild" && cmake .. && make) 1>/dev/null || return 1
}
...
```
## 4. Ejecución
- Buscar última versión de librerías (únicamente wxWidgets por ahora)
- Compilarlas si es necesario
- Loggear y retornar códigos correctos
```sh
! get_latest_wx && error "Checking, downloading, or extracting failed." && exit 1
if [ "$latest_wx" != "$current_wx" ] ; then
consolelog "Building wxWidgets..."
! build_wx && error "Building wxWidgets failed" && exit 1
success "Built wxWidgets"
else
binary="$(find ./ -name 'wx-config')"
[ -n "$binary" ] && success "Found $binary, skipping building wxWidgets"
if [ -z "$binary" ] ; then
consolelog "Building wxWidgets..."
! build_wx && error "Building wxWidgets failed" && exit 1
binary="$(find ./ -name 'wx-config')"
[ -n "$binary" ] && success "Built wxWidgets"
[ -z "$binary" ] && error "Can't build wxWidgets" && exit 1
fi
fi
```
